Wan Lin listened to the voice and involuntarily walked outside.

I saw that the surrounding city wall was piled up with groups of materials, and it actually formed a small wall up to 5 meters high, which surrounded the entire base area.

The place where it used to be a fence gate has been turned into a steel gate, and there is a button on the side of the gate, which is supposed to be the switch to open the door.

At the same time, a thin layer of blue light shrouded the top of the city wall, like a protective shield.

Wan Lin was amazed, then flashed his eyes and rushed back into the foundry, starting to check the details of the level 3 city wall.

The Level 3 wall has the function of maintaining the air in the base area because of the fusion of protective shields, and at the same time, when the city gate is opened, it will also have the function of protective shields.

However, the protective shield and the city wall are integrated, and its own protective effect is only used in the blank space of the entire base area.

However, the city wall is fused with the armor of mutant creatures, which greatly enhances its defensive effect, and it will no longer be attacked by thousands of mutant creatures like a protective film, and it will be so badly lost.

Moreover, 4 towers can be built on top of the level 3 wall, and the original tower can also be upgraded to a level 3 tower without the need for additional drawings.

"Ding! Congratulations to the host for building a level 3 city wall independently and opening the mall blueprint module! ”

Wan Lin was stunned for a moment, then clicked on the mall, and sure enough, he saw an extra label on it, and when he clicked on it, it was all architectural drawings.

A lot of the drawings are grayed out and don't meet the conditions for unlocking.

But at the same time, he saw that all kinds of drawings of level 3 were lit up.

The wall blueprint is already in possession, and it can no longer be purchased, and there are many other drawings for the rest.

Workshops, foundries, and domestication workshops are all available.

Wan Lin looked at these drawings excitedly, and then saw the price marked below, "500 pieces of brilliance!" ”

It's so dark!

A single blueprint sells for 500 Radiance!

He has worked so hard to earn glory, won't he squander it immediately!

"Ding! Trigger Side Quest: Expand Base (1)! ”

"Mission content: A basic base area has been built, but in order to better survive on the earth and better complete the task of planting the sun, the base area must be expanded! First of all, you need to get the upgrade items of the herb seeds in your hands here! Ore source: Lava Crystal Source*1, Teareye Stone Source*1! ”

"Reward for completing the mission: Unlock the level 1 mine blueprint, 1000 brilliance!"

Wan Lin took a deep breath and looked excitedly at the rewards of the new mission, which doubled again and became 1,000 Glory!

Sure enough, the rewards of the mission are getting better and better, and he can already foresee that he will soon be able to raise Little Sun to level 1.

Wan Lin wanted to do this task right away, but he hesitated.

Because on his task page, there is another task, which has been sent out a long time ago, and there has been no progress so far, that is, the task of saving mutants.

Xiaoqing's upgrade is still there, and it will be completed soon, but this task of saving mutants has not been done at all.

Seeing that the number of mutants has dropped to 18,670, it is more than 6,000 less than before.

Wan Lin frowned, before the siege, he had also seen the mission layout, the mutants of this mission had not been sharply reduced so much, but after the siege, it had been sharply reduced to this point.

Could it be that those mutant creatures will also attack mutants?

Thinking of this, a strange look appeared on Wan Lin's face, could it be that those mutated creatures were not only attacking their base at that moment, but also other mutated creatures in other places on the earth were attacking other places?

Wan Lin then couldn't sit still, if this was the case, then although those humans had mutated, they were still alive, and it was impossible for him to watch those people lose their lives.

Wan Lin decided to do this task of finding mutants first.

He looked at the surrounding city walls, first defended his base area, and then went to other cities to look for it.

Wan Lin returned his attention to the virtual building in front of him again.

He had to build all four level 3 towers first.

To upgrade to level 3 towers, you only need to add some more stone just now.

Wan Lin immediately clicked on the existing tower to upgrade, and by the way, the other 3 towers were also upgraded.

The current base looks like a small castle from a distance.

It is surrounded by a 5-meter-high city wall, on which people can stand, and there are stone steps behind the city wall to walk up.

At the same time, there is a tower at the corner of each wall, and the range of the tower's arrows covers an area of 800 meters around the entire base area.

Wan Lin looked at his base proudly, walked into the toilet with satisfaction, washed up, and changed into clean clothes, he took Xiaoqing, packed his luggage, and prepared to embark on a new journey again.

This time, he is going to save the mutated humans on the earth, and save those who are still in dire straits!

Although Wan Lin is still a little worried.

He feared that the mutated humans no longer belonged to the same race as him.

In other words, he is afraid that those mutants have lost their minds, and human beings without intelligence can no longer be called human after all.

Wan Lin shook his head, let's not talk about human righteousness, let's talk about the task.

Then even if those humans lose their minds, since the system has issued this mission, there must be a way to bring some people back to the base area.

In the same way, if you want to live in the attached base area on the edge of the base area, you should at least be able to take care of yourself, right?

Wan Lin thought about many possibilities, but he couldn't guess why, so let's take one step at a time, first of all, he had to find out the mutant first.

Wan Lin took out the space shuttle door and chose it for a long time, which city should he choose?

He recalled the news from the past.

Twilight is a new city, most of the people come to work, and then live here, there are fewer elderly people here, and because they are all workers, elites from various industries gather.

This leads to Twilight's order to forcibly relocate the entire city.

But in some cities, there are also many people who do not agree with the evacuation of humans, such as Wenyan City.

The news mentioned that the citizens of Wenyan City had clashed with law enforcement officers on several occasions, saying that they would not evacuate the earth and would not let the law enforcement officers move supplies.

This time there was a lot of trouble.

It's a pity that in the news later, Wan Lin didn't pay attention to it anymore because he was busy with work.

But that didn't stop him from deciding to go to the city first.

"I chose Wenyan City!"

Wan Lin searched for the city on the space shuttle door, then clicked OK, and waited until the prompt light of the space shuttle door turned green, he opened the door and walked in.

In a dark and lightless city, a door appeared in one of the squares, and the door gradually opened, revealing a bright light.
