After breakfast.

Fang Hao took black Jing and twenty bone dragons, loaded with skeleton trolls, to the edge of the bloody mountains.

After about an hour's journey.

Finally arrived at the destination.

First, I sat in the bone dragon and flew down the mountain. I observed it carefully one by one.

"Sir, if the blood throat tribe in your mouth wants to attack, this is their only way."

The bone dragon fell, and Heijing pointed to the map and said.

The map records the nearby mountains. There are continuous mountains around. Only at the foot is a mountain path, which is also the way they went to the buried Dragon Cave last time.

In fact, there is another one, which is the secret road in the mountain when they come out of the Dragon burial cave.

Fang Hao has arranged for people to go back to get the black powder and plans to block it directly.

"Yes."

Fang Hao opened the Lord's book and turned to the page of architecture.

Find the [fortress] drawing from it.

[first class fortress: Wood 3000, stone 2000, stone brick 1500, iron 500, metal parts 120.]

Between the two mountains, choose to build directly.

The light flashed and a fortress was built.

Directly upgraded the fortress to level 6.

[level 6 fortress]

[category: defensive building]

[ability: Fortress]

[fortress: building defense durability increased by 1%.]

[materials required for upgrading: Hardwood 3000, stone brick 5000, iron 3200, metal parts 500.]

After rising to level 6, the ability of Fortress appears, which can increase durability by 1%.

Nothing is better than nothing. I hope I can stop the troll's attack on the battlefield.

In Fang Hao's view, the fortress is like a medieval castle in the West. The wide and thick walls connect the mountain walls on both sides to form a defensive barrier.

In the center of the city wall is a tall and heavy gate, which can ensure normal walking on weekdays.

It is more than 5 meters wide above the city wall. Archers and mages can be arranged above it, or some weapons and instruments for guarding the city can be placed.

Military barracks, civilian houses and blacksmiths can be built inside without any restrictions.

It's not much different from a small city.

by the way!

Fang Hao patted his head.

Since these can be built, the arrow tower and defense magic tower should also be built.

Open the Lord's book again and build arrow tower and defense magic tower.

When the light appears, two kinds of defense towers have appeared.

If you raise the arrow tower and magic tower on the city wall to level 6, you'll have to place the corresponding arms.

"Black wattle."

"My Lord." Black Jing came over.

They stood on the wall and looked at the depths of the mountains in the north.

"What else do you think needs to be arranged to resist trolls here?" Fang Hao said.

Black wattle's skills include city guarding skills, and he was also the commander of the orc army all the year round. He should have sufficient experience.

I hope Nelson didn't get rid of his knowledge.

Black Jing stood aside, thought briefly, and said, "my Lord, the troll's advantage lies in its size and strength. The height of the city wall is enough for defense, but we should try to delay the troll's speed near the city wall and increase the time to attack."

"Then build some roadblocks? But they are also easy to be damaged. I'm afraid they won't be blocked for long." Fang Hao thought of resisting the horse and shook his head in self denial.

Fang Hao has been in contact with ogres and knows some of their combat characteristics and physical advantages.

It has great strength and thick skin.

Unless you attack their vital points, even if you stab them, the effect is not great.

Those mass-produced roadblocks are still suitable for hindering human body size.

Blocking trolls must also work, but the effect is much less.

"No, my Lord, I mean we can dig a trap that trolls can't cross to hinder their attack speed." Black Jing looked down, "but I'm afraid the quantity of this project will be larger."

This is the cold wind mountains.

Even the ground under your feet is hard rock.

If the fortress is not built with drawings, it is difficult to dig out the foundation if it is built by manpower.

Excavation and stone planing are two different quantities.

Moreover, the enemy's attack was right in front of him. He dug a big pit to hinder the troll. Heijing was worried that there was not enough time.

But Fang Hao feels very good about this proposal.

Who says the quantities are big, he doesn't feel big.

"That's a good proposal. You study the location and length of the trap, and I'll transfer people." Fang Hao said.

"Oh, OK."

Heijing promised, walked down the wall and began to plan the location of the trap, as well as the depth and width that could hinder the troll.

Fang Hao opens the Lord's book and contacts Zhang Bin.

"Zhang Bin, are you there?"

"Boss, get up so early."

"Wait, I'll send someone to pick you up and bring all the iron clawed rats."

"Oh, OK."

Then Fang Hao hung up their chat.

Soon, the Blood Hunter flew over on the bone dragon, just landed and jumped off the bone dragon's back.

With a barrel of explosives in his arms.

"My Lord, where are these explosive barrels?" Asked the Blood Hunter.

"Here, I'll take you."

Fang Hao took the blood hunting to the mountain tunnel that can lead to the outside world.

The explosive barrel was thrown in.

After the huge roar, the tunnel collapsed and was completely blocked.

"Blood hunting, go to Zhang Bin's territory and pick him up with the iron clawed rat." Fang Hao continued.

"Yes, my Lord."

Blood hunting left again with the bone dragon and went to Zhang Bin's territory.

About two hours.

When the bone dragon returned again, Zhang Bin also came with groups of iron clawed rats.

When the barrel was put down, the iron clawed mouse scattered in an instant, stretched its neck and looked at Fang Hao, who had not been seen for several days.

Fang Hao also looked at the iron clawed rat curiously.

These little guys are very different from the first time we met.

Some wear rings around their necks, some wear leather helmets, and some even fit clothes.

Anyway, everyone is different. It's a lot more lovely.

"Boss." Zhang Bin came over.

Now I'm used to riding bone dragon. There's nothing wrong with it.

"Is this an animal beauty contest?" Fang Hao looked at the iron clawed rat with a curious face and stretched his neck to one side.

"Oh, isn't this distributed to the residents door to door? Everyone made some marks in order to identify their iron clawed rats." Zhang Bin explained.

The iron clawed rats are almost the same. The residents are afraid that they will not recognize them when they are fattened.

They marked their hats, rings, and shaved the hair on their hips as identification.

"All right, you command them. Start digging traps according to Heijing's plan. Finish digging and finish work quickly." Fang Hao pointed to the black wattle.

"Oh, OK." Zhang Bin went out with the iron clawed rat and began to dig traps on the ground according to the plan.

The scene of earth and rock flying and more than 500 iron clawed rats digging the ground is still quite spectacular.

……

At this time.

Two more bone dragons fell from the air.

Anja jumped off the dragon's back, followed by Patty.

On the back of the second bone dragon, nine orcs were thrown down.

As soon as he got down, he knelt down on the ground with his legs soft.

"Here, this is the slave contract. There are nine tribes in total. Four have just been destroyed." Anja handed over a pile of slave contracts.
