In the last days, I will become stronger through synthesis

Chapter 220 Upgrading the City Wall
Ye Chen, who had already left the room at this moment, did not leave the gate of the base, but went directly to the top of the city wall.

Here, you can directly overlook his entire base, and make a reasonable layout. More importantly, of course, it is still enjoyable.

For the current plan of the base, Ye Chen already had a blueprint, but because he didn't have time, he just put it on hold.

But now the interior of the base is stable, and there is nothing he has to do outside, so he can finally realize his own vision.

However, he was not in a hurry, but directly issued a message to all the new citizens through the ID card, telling them to leave the building and bring their valuables with them.

This notification is an urgent notification. After Ye Chen sends it, everyone's ID card will make a ticking sound.

And when everyone made the sound of ticking in unison, Ye Chen had a panoramic view of how spectacular the scene was.

Everyone was taken aback when they saw Ye Chen's notification, but when they saw the countdown time limit on the notification, most of them walked out despite being helpless.

Naturally, Ye Chen didn't worry so much. When half an hour was up, a three-dimensional perspective of the entire base immediately appeared in front of Ye Chen's eyes.

At the same time, with a wave of his hand, Ye Chen included countless buildings in the school, and then, Ye Chen chose to sell these buildings directly!
【Ding!You sold the cluster building and got 1000001 synthetic coins]

Before the system's prompt was over, Ye Chen suddenly saw that the house in the distance made a violent roar and exploded!
Think about it, in the entire base, dozens of high-rise buildings were blasted in an instant. How shocking is that scene!
Not to mention ordinary newcomers, even Kong Yishan, who just came out of the cafeteria, and Ye Chen himself were startled by this sudden scene.

"Haha! This is really cool! No wonder everyone likes to destroy, it's so sour, how cool!"

Ye Chen made a loud noise, he was the only one on the top of the city wall at this moment, so he didn't have to care about his image and had no scruples.

But looking at the vacated venue, Ye Chen showed a smile at the corner of his mouth.

But Ye Chen's transformation is not just a piece of building, but the entire base!

So, standing on the city wall of the base, Ye Chen kept gesticulating, and then, the buildings inside the base were blasted one by one and turned into rubble.

Ye Chen had a good time here, but he probably didn't expect that the whole base would go crazy because of his actions!
When Ye Chen stopped the demolition contentedly, there were only three buildings left in the base, the teacher's apartment, the library and the gymnasium.

The teacher's apartment, because it was Ye Chen's house and it was next to the power supply room, so he didn't demolish it.

The library was left because there were still many books in it, and he didn't have time to synthesize skills, so he stayed.

And as one of the few activities after Doomsday lost the Internet, Ye Chen needs to keep it to add a little entertainment to the people in his base.

Otherwise, the crime rate of the entire base may increase a lot by then.

As for the gymnasium, it's even simpler. The four Quanlu and Li Qiu who may ask for information about the new human base are locked inside.

As for the others, Ye Chen naturally had no worries, so they were all demolished to make room for the entire base.

In fact, Ye Chen didn't even spare the street lamps and flower beds on the ground at this moment, and recycled them all.

But after this recovery, Ye Chen suddenly discovered that the amount of his synthetic coins had soared to tens of millions!
Seeing this, the smile on Ye Chen's face became even more joyful. There are too many things that can be done if there are ten million synthetic coins.

But the first thing to do is the defense facilities of the base.

So at this moment, Ye Chen directly clicked on the city wall without saying a word, and upgraded again.

【Ding!Whether to upgrade the city wall, the current cost: 5 0 0 0 0 0 synthetic coins. 】

50 synthetic coins is like drizzle, promote him!
After His Highness confirmed, the entire base began to shake again, and Ye Chen, who was standing on the city wall, felt that he was constantly rising.

Not only that, but at this moment he found that the wall he was standing on was not only taller, but also wider!

When the shaking stopped, Ye Chen was even more surprised to find that the height of the city wall of the entire base had reached a hundred meters!
At this moment, the width of the city wall, even at the very top where Ye Chen was standing, was a full six meters wide.

Because the entire wall is a trapezoidal shape that keeps going up, the thickness decreases from bottom to top. Therefore, looking at the city wall below, Ye Chen can clearly see that the overflow distance of the city wall may have exceeded 15 meters long ago!
If you look at it from the side, the entire wall of the New Order base looks like a round turtle shell, and the bottom of this "turtle shell" is as thick as 15 meters!
With this thickness, let alone hero-level zombies, I am afraid that now epic-level zombies are coming. Ye Chen also dares to say that this city wall can withstand a single resistance.

However, at this moment, Ye Chen suddenly discovered that the top of the city wall in front of him actually emitted a faint white light.

Ye Chen poked forward curiously, and was surprised to find that the surrounding wall actually had a protective layer on the top!

Ye Chen's eyes flashed with surprise, and he took out a handkerchief from the system space and threw it over.

In the end, something unexpected happened to Ye Chen. The handkerchief was actually blocked by this light curtain!
Ye Chen stretched out his hand to touch it, and was surprised to find that the film of light in front of him still had a body!

Ye Chen's eyes lit up, and after a little thought, he boldly stretched out his feet and stood directly on top of this light curtain!
After walking back and forth and finding that there was no problem, Ye Chen was even more determined and couldn't help laughing.

At this moment, it is completely certain that this upgrade of the city wall not only widens and heightens the city wall, but also adds a layer of nano protective film to the sky above the base!

In this way, the entire base became a fully enclosed base, not to mention alien zombies, I am afraid that even flies would not be able to enter.

Thinking of this, Ye Chen returned to the edge in satisfaction, and opened the system mall again.

The city wall is over, so the next thing is naturally the defensive building.

There are too many gaudy defensive buildings, but according to his current base level and materials, Ye Chen can't even afford the Vulcan Machine Fort.

Therefore, he could only settle for the next best thing, and chose a cheaper machine gun turret [Full-automatic heavy machine gun turret]
