Chapter 715

Ren is very clear about Kerstagin's thoughts.

The King of the Hill covets the throne of the Highest Mountain Kingdom and wants to replace him, which has caused irresolvable hostility between him and Thorgreen, but his personal ambition does not affect his ideal of restoring the glory of the dwarves. The two are highly consistent of.

The powerful electro-optical cannon will undoubtedly greatly help Kerstakin realize this lofty ambition, even if he is loyal for life.

Other dwarves also realized the great effect of the electric light cannon.

Ren is not disgusted with the intentions of these dwarves. The two parties are still collaborators and allies. If they can help, they will help.

Unfortunately this is not possible.

The most important core component of the electro-optical cannon is the brain-splitting chip. With computing power far exceeding the limit of the human brain, it can precisely control the energy transmission and release of the Titan engine. Combined with optical knowledge, the spell of "electro-optical ray" has reached an incredible level.

All of these are the products of the mutated mobile phone and the heart of the mastermind. They are unique, and no one can make them except themselves, not even Master Ogulev.

Even if he told Kerstakin the exact method, he couldn't make an electric light cannon.

Facing the desire of the dwarves, Ren shook his head decisively.

"The core technology of the electro-optic cannon involves my demon soul." Ren said seriously: "Except for me, there is no other person in the world who can make electro-optical cannons."

Kerstakin looked disbelieving.

I am a majestic rune lord, the most brilliant craftsman and alchemist of Allen Erth, how could he not make it as long as he got the blueprint?

The dwarves thought that Ren was just making an excuse to refuse, but they could only sigh in a low voice.

Why should such a powerful invention be taught to the dwarves?

Ren saw through their thoughts at a glance, and said again: "I can give you a copy of the rune array and design of the electro-optic cannon, Kerstakin, you can try it yourself, but make sure you don't spread it outside."

Since it will never be possible to manufacture electro-optical cannons, they must give up their hearts from the very beginning.

"good!"

Kostakin was heartbroken, but at the same time full of confidence, he said loudly: "I swear in the name of Grimnir, I promise not to leak the design of the electro-optical cannon."

Ren shook his head in his heart and didn't say anything to hit him.

The rune array of the electro-optic cannon only plays a secondary role. After mastering it, Kerstakin will find that without the Titan engine and the brain-splitting chip, the power of the electro-optic cannon cannot be achieved at all, but it is just a mediocre rune method. The array is only capable of stimulating electro-optical rays.

Ren glanced at the turret, turned around and was about to leave.

Blestein stopped him, "My lord, do you want to send a team of dwarf warriors from the Three Hammers to strengthen the guard against the electric light cannon?"

"No need to waste manpower, just patrol the city wall normally." Ren shook his head and replied.

The dwarves froze.

Isn't there a special guard for such an important weapon?

Ren smiled and explained: "The electro-optical cannon has a self-defense mechanism. If an enemy approaches, it will automatically counterattack. If you haven't reached the legend, approaching the electro-optical cannon is a dead end."

The electro-optical cannon is essentially a clone of himself.

In addition to the three fire modes of long-range attack, it also has a strong protective ability. Although the electric shield activated by the Titan engine has only eight rings, with the support of huge energy, its defense ability is no less than that of nine-ring spells.

In addition, the "serial lightning" and "advanced thunder" that can be released when the enemy is approaching, the brain-splitting chip has its own telepathy, and is connected to the six "secret eyes", leaving no dead spots for detection.

The brain-splitting chip is always on standby, tireless and without rest.

It is more reliable than any guard in itself.

The dwarves looked at each other, they had never seen such a magical weapon, but Blestein was still worried: "What about legendary enemies?"

What he was worried about was that the electric light cannon was robbed.

"Don't worry, the electro-optical cannon will respond correctly." Ren patted the shoulder of the chief craftsman, "No one can steal the electro-optic cannon. If someone does this, the end will be miserable." The corner of his mouth raised A quirky smile.

Even if someone breaks through the protection system of the electro-optical cannon, wants to destroy it, or even loot it, the electro-optical cannon still has the last trump card - self-explosion!

The Titan engine model of the electro-optical cannon is different from that of the power armor. It is larger, more powerful, and consumes more source crystals.

It uses a medium-sized standard source crystal rod, which weighs a full eighty pounds.

With so many high-purity source crystals exploding, the lethality exceeds most nine-ring spells. The temperature and impact force at the center of the explosion are enough to kill holy-level powerhouses with insufficient protection or caution.

In other words, the electro-optical cannon is actually a magic trap.

If an electro-optical cannon can exchange the life of a holy-ranked powerhouse, it would be worth it! Not counting labor costs, the cost of an electro-optical cannon is more than 79,000 gold shields, which is close to 80,000. A mere 80,000 gold shield killed a holy rank expert, even if it only killed a legendary high rank, it was blood money!

Ren suddenly looked forward to it.

After explaining a few words carefully, he made a tour of Gotham City, and then returned to Fort King Kong.

Kerstakin followed to get a blueprint of the electro-optical cannon, and immediately returned to Gotham's highland fortress as if he had found a treasure.

Ren once again buried himself in the research and development of power armor.

He himself was doing research, but the Thundercast Heavenly Soldiers didn't sit idle for a single day. They manufactured electric light cannons at a rate of almost one every day, and once they were completed, they were sent to Gotham immediately.

A quarter of the city wall has just been built, but this does not affect the installation of electro-optical cannons.

According to Rennes' request, Blestein first built a small section as a turret on the foundation where the city wall had not yet been built. The distance between the two turrets is controlled within two miles. This is the effective range of the electro-optical cannon in the burst mode. If the enemy exceeds two miles, the range in the bombing mode will reach 3,000 meters, which is enough to form a firepower network covering the entire city wall. .

Ten electro-optic cannons were installed on the twenty-mile-long city wall, but this was far from enough.

The west end of Shield Island is more than forty miles along the coast, and the northern half is a strait, the widest part is only more than 200 meters. The undead can easily cross over from Abraken on the opposite side, so a wall must be built.

The southern half is a wide bay, which is also one of the two best natural deep-water ports in the New World. It is shaped like a bottle with a narrow neck and a wide belly. For nearly three miles, it has been able to stop most of the army of undead who cannot fly.

But there are still some undead who can fly.

So, Ren asked Blestein to build a turret every two miles along the shore, and also installed electro-optical cannons to block the exit of the bay.

The wall turrets are a line of defense only against enemies from the west.

And the enemy will certainly attack from the east.

The wars of Arrenus are always inseparable from teleportation, and the actions of the Scourge are always inseparable from the liches and necromancers of the Knot Seal.

They will send the undead army directly to the shield island, bypassing the city wall and attacking from the east.

However, in larger-scale battles, the role of the portal will be more limited, because the number of troops is too large. If the teleportation array is not built in advance and only rely on casting spells to open the portal, it will be too late to transport many troops.

The Scourge's biggest advantage is numbers, which also restricts their mobility.

The optimal strategy is to send only a small number of elite troops, and let most of the troops march on a regular basis, forming a multi-faceted attack.

Therefore, the Scourge's offensive is also easy to judge.

Apart from the city walls, Gotham City's demarcated urban area is still a large area of ​​open space. The east side is flat and there is no danger to defend. The only thing that can attract the undead to attack is the high ground fortress in the city.

To the east of the highland fortress, Rennes selected a dozen points to build turrets, forming an arc-shaped defense line.

Finally, four electro-optic cannons were installed on the top of the highland fortress, covering a range of two miles around the fortress. Residents and dwarves artisans who migrated to Gotham one after another live here. The four electro-optic cannons are used to protect them .

It took more than a month, and the Thunder Cast Heavenly Soldiers produced a total of thirty-five electro-optical cannons.

This takes up thirty-five places for brain-distribution chips.

Ryan's chip quota is still enough. He just earned 5 million gold shields from Thorgreen, and he is not short of money now. However, considering the huge investment in Gotham City, he still needs to save some money, so he temporarily stopped making electric lights. gun.

Time passed day by day.

Nearly three months have passed since the day the construction of the city wall started.

Two-thirds of the tall city wall has been built, more than fourteen miles, and it was built from both ends at the same time, just like digging a tunnel, and finally joined together in the middle.

The gap in the middle of the city wall is nearly six miles, and it is closing every day.

During this period, every now and then, a small army of undead would attack across the water surface of the strait, trying to interfere with the construction of the city wall.

This is an obvious temptation.

The Thundercast Heaven Soldiers sent out were scattered in Abraken, and found that the army of undead was gathering, and the number had doubled compared to before, reaching more than 70,000. However, undead of this scale are not too many for the Scourge, or even a drop in the bucket.

Historically, the Scourge has dispatched at least hundreds of thousands, and millions are also common.

This made Ren a bit strange, and the Thundercast Sky Soldiers lurking in Abraken did not find that there were many legendary and above powerhouses among the undead.

Counting and counting, there are only a dozen legends, most of which are elementary and intermediate.

The ranks of the undead that make up this army are not high. They are mainly elementary and middle ranks, and the proportion of high ranks is less than 1%. It cannot be called an elite army at all.

All kinds of undead creatures are mixed together, like a motley army.

Ren secretly asked the Thundercast Heavenly Soldiers to expand the scope of investigation, circled a large circle around the Abraken area, and found that in this area of ​​thousands of square miles, the tombs of the undead were almost empty.

Obviously, these undead are just a vanguard.

The main force of the Scourge has not yet arrived.

After Ren made a judgment, he only let the Three Hammers and the Ultramarines eliminate the small group of undead who came to interfere, and did not let the electro-optical cannon fire, so as not to attract the attention of the Scourge. During the electro-optical cannon test that day, Ren deliberately chose a relatively remote location and opened fire after making sure that there were no undead lurking around.

An army of 70,000 to 80,000 undead is hiding in a river valley north of Abraken, more than 30 miles away from Shield Island.

Since they are not moving in large groups, Ren is also happy to do so, not to startle the snake.

With each passing day, the city is getting closer to completion. After the city wall is built, it will be very difficult for the Scourge to break through Gotham City, and the difficulty will increase by at least ten times!

However, Ryan did not take it lightly.

There is also a possibility that these undead are just illusions released by the Scourge. Maybe one second is calm, and the next second, the Xinxiang Floating City they control leaps to the sky above Gotham.

As the city wall was built day by day, the gap in the middle gradually narrowed.

Suddenly, Ren, who was immersed in research, looked up.

In the river valley north of Abraken, the originally silent ground suddenly rolled violently, the river became turbid, and countless undead came out of the underground and hidden caves. Soon, the mountains and plains were crowded with dense undead creatures.

Zombies, skeleton warriors, skeleton shooters, ghouls, water ghosts, nerubians, soul weavers, ghost servants, bone structures, ghost cavalry, ghost sentries, shadow lurkers...

Thousands of gargoyles, wraiths, and ghostly bats soar into the sky, casting shadows that block the sky.

On the east side of the valley, a Thundercast Heavenly Soldier merged into a thick withered tree trunk invisibly, monitoring the movement of the valley.

He found the leader among the undead army.

A legendary high-level death knight, beside it, there is also a haggard lich in gorgeous robes. The eyes of the soul are too far away to see clearly, and it can only be roughly judged that the level of the lich is 18 or 19 , but it must not be the Holy Soul Lich.

The death knight rides a ghostly steed that can fly through the air, and directs the army forward.

They headed south, aiming at Shield Island.

Everything that the Thundercast Heavenly Soldiers saw, Ren also saw at the same time.

He immediately stopped his work, teleported to Glamorgan, and notified the teacher through the Wezeland badge. At the same time, he sent a message to the ancient red dragon with the magic communication stone given to him by Hell Flame, asking it to tell Elder Titan. Get ready for battle.

At the same time, more than twenty Thundercast Celestial Soldiers in the mechanical alchemy room also stopped working, quickly put on golden armor, and jointly opened the portal.

The Ultramarines and Spearwing Knights who stayed in Fort Vajra entered the portal in an orderly manner.

The portal to Glamorgan also opened.

The two extraordinary legions teleported step by step at the fastest speed, using Jianwan Town as a transfer point, and they all arrived at the highland fortress of Gotham City in just a few minutes.

Ryan arrived in Gotham one step ahead of schedule.

The Thundercast Sky Soldiers stationed here have already told Kerstakin about the movement of the undead army. The King of the Hill acted vigorously, and the 5,000-strong Dwarf Legion moved. The dwarf craftsmen and the more than 10,000 human residents who have moved here are all concentrated in the direction of the highland fortress.

Ren teleported to the city wall and appeared next to Kerstakin.

The King of the Hill looked at Abraken on the other side of the river, and saw only the dry and twisted black forest, which was still silent.

The undead army is still far away.

But Kestakin didn't relax at all, his eyes were full of dignity, he looked back at the Highland Immortal Fortress in the city, and tall Ultramarines were pouring out of the fortress. There are also flying horses that seem to be made of bronze, vibrating translucent wings and flying into the sky, flying towards the east.

As planned, the Ultramarines stayed behind at the fortress.

After the Ultramarines finished teleporting, they found that the teleportation array was still in operation, and the Thundercast Celestial Soldiers hidden in golden armor appeared one after another. They were holding bolters and lightning hammers, and the aura emanating from them made even the Ultramarines look sideways at them .

The Ultramarines knew that the Primarch had cultivated a new legion, and they had all seen the Stormcasters, but they didn't expect there to be such a large number, there were more than a hundred!

On the city wall, the Three Hammers are already in place.

Iron Shield Guards and Wildhammer Warriors are at the forefront, Musketeers and Hunters are at the back, and there are Dwarven Mage and Priests. Some priests who have gone out to purify the land are rushing back.

In addition, there are more than 60 Wezeland wizards, which are already members of half of the Wezeland wizard group, and there are many legendary wizards among them.

These superhumans gave Kerstakin great confidence.

Of course, the greatest confidence comes from Rennes around him.

Kerstakin looked at Ren, the young man's face was still calm, without the slightest fluctuation, as if everything was under control. Ren's strength and complete preparations eliminated the last trace of uneasiness in the hearts of the dwarves.

A moment later, a shadow appeared on the northern horizon.

The undead are coming!
