After the meeting.

Huang Wuji, Jiansheng and Yiye Guzhou are walking with Zhang Yi on the street of purgatory city.

At this time, Huang Wuji didn't understand: "can these defense towers really resist the ghost army?"

"After all, the defense function of this temporary defense tower is certainly not as high as that of the secondary main city. Why don't we start defense directly in purgatory city and choose to build a defense tower?"

"That's a good question!"

Zhang Yi said, "because the purgatory city is too big, our next preparation can't cover the whole purgatory city."

"But the defense tower is small and can enter a comprehensive defense posture."

"Next step?" the swordsman asked, "what else to prepare?"

"These defensive towers alone can't stop the invading army of the ghost clan."

Zhang Yi said, "if you inject some element spar, it will be different."

"This is the last step we need to prepare before facing the ghost clan."

With the introduction of Zhang Yi, everyone learned that.

The original Apocalypse world, there is a mysterious prop that can be used to restrain the ghost family: Elemental crystal!

However, elemental spar can only be used with buildings, not directly against ghosts.

It's the same as sprinkling salt water on the city wall, which can prevent ghost wizards from directly penetrating the city wall.

If the elemental spar is strengthened, the defense of the building against the ghost clan will be more powerful!

Even through different kinds of element spar, it can bring offensive effects to buildings!

Hearing Zhang Yi's remark, the crowd immediately became interested: "where can I get this element spar?"

"Elemental spar, guarded by goblins."

Zhang Yi said, "this is the product of the goblin kingdom."

Lin Xi didn't understand: "goblins? What's that?"

"I know! Goblins living underground!" the sword Saint raised his hand and shouted.

As a result, it attracted people's eyes.

Unexpectedly, Zhang Yi said, "yes, goblins are underground goblins."

People were shocked: "do you want to be so hasty..."

"Goblins live underground all year round, so it is difficult for ordinary people to see them."

In fact, goblins can also be understood as a race in the apocalyptic world!

But this race is too weak to compare with Terrans, demons, aliens, dragons and ghosts.

They have lived underground for generations to produce elemental spar, and then sell elemental spar to other races to earn some food.

Under each player's main city, there are goblin territories.

But to find them is not to dig three feet.

Because they live thousands of meters underground, ordinary excavation can't dig that deep.

They all have special underground passages leading to the goblin kingdom!

Naturally, the reason why Zhang Yi knows this is from the memory of the previous life.

In the last generation and later generations, when building the main city, some players found that the main city built with the combination of elements and crystal stones had an amazing super defense effect against the ghost family when the ghost family invaded on the ghost festival!

But elemental spar is very scarce.

In order to snatch the elemental spar, the players of all major families even broke out battles repeatedly!

At this time, Yip Guzhou said to Zhang Yi, "Sir, do you know where the channel to the goblin kingdom is? I'll take someone to the goblin kingdom to buy elemental spar immediately!"

Zhang Yi shook his head: "I don't know."

"However, we don't have to look for it deliberately. When the time comes, the goblins will send the elemental crystal to each main city."

"Is there such a good thing?" they thought strangely.

Through Zhang Yi's description, we learned.

Originally: goblins, in addition to being weak, have a special ability to predict disasters!

This year is the first year of the ghost invasion. All major races are completely unaware of the upcoming ghost attack.

The goblins predicted the coming danger!

Just as: if God closes a door for you, it will open a window for you.

And they foresee that elemental spar can be used against the coming enemy!

Therefore, every year, the goblins will bring the elemental crystal stone to the main city of the three races three days before the ghost festival. They want to help the three races fight the ghost race. At the same time, they also exchange the elemental crystal stone for some food.

This is also the reason why Zhang Yi did not look for the goblin kingdom in advance and reserve elemental spar in advance.

Unfortunately, those goblins can't speak.

At least for the first three years, the three races will not realize that the elemental spars produced by small goblins can be used to effectively fight against powerful ghosts!

Therefore, according to the historical progress, in the past few years, every year, there were ugly goblins with an earth bag in the main cities, and players and NPCs would drive them away directly.

Zhang Yi looked at the time and said, "goblins should appear in the city the day after tomorrow or the day after tomorrow. Then all of you should pay attention."

Huang Wuji, Jiansheng and Yiye Guzhou answered one after another: "understand!"

At the same time, Zhang Yi also forwarded the news of goblins and elemental spar to the dragon family in Liuguang city.

Liuguang City, although there will no longer be a crisis of ghost invasion.

But goblins will appear on time.

When you go to the first level main city to create a city in the future, you need a lot of elemental crystal stones to make the city have absolute power to defend against ghosts.

Therefore, it is necessary to collect elemental spar in advance!

So for the next two days, nothing happened until the goblins appeared.

Zhang Yi is nothing more than brushing monsters, practicing grading and teasing minibuses.

The intimacy of the minibus seems to be stuck at 99%, and it can't rise!

This is really a headache.

In addition, Zhang Yi stays with Lin Ruo and Lin Yi every day.

After seeing their sisters meet again, their feelings are getting better and better, and a trace of hesitation can't help but appear in the bottom of my heart.

During this time, Zhang Yi deliberately contacted Lin Ruo several times through various opportunities and used the heart of memory to copy Lin ruo's memory.

Found that her memory is very pure, without any bad heart!

Is it because Zhang Yi tampered with some of the history of this life that Lin Ruo will not get worse in this life?

Zhang Yi still can't believe this. He cheated his woman for seven years in the last life!

It's better to be on guard.

But even if it's revenge against Lin Ruo, Zhang Yi must wait until she helps the fat man through the last life-threatening crisis!

In the suffering and waiting, I spent two days like this.

The time came on July 12 of the lunar calendar.

That night, Zhang Yi was practicing alone in a 190 level senior wild area outside the city.

Suddenly I received a private message from Yu Jiansheng: "boss, the Goblin you said seems to have appeared!"
