"A small soldier under his command, born in a farmer's household, has a lot of ghost ideas." Wei Changfeng said with a smile, this moment is a bit freehand.

"It's really good." Li Yi watched the mutant rat retreat and said sincerely.

On the other three walls, the fighting continues. But at the main entrance, it has stopped. The fire is not so easy to extinguish, so it is still burning. The soldiers stole their free time, but they were also solemn and did not dare to stay away from the battle line.

The strong fireworks roasted for a long time, and Li Yi and them were like roast suckling pigs on the fire rack, but what came out of the roast was sweat instead of grease.

"Oh no." Suddenly, a small soldier noticed the situation and shouted loudly.

"What's wrong?" Wei Changfeng's military uniform was wet with sweat, and in order to be decent, he didn't take off any of it, which was much hotter than Li Yi. But the good mood is still the same, even at this time, he asked calmly.

"The walls are cracked!"

"What? How so? Wei Changfeng, who heard the news, couldn't calm down anymore and exclaimed.

"It must have been so hot that the soil of the city wall was burned." Li Yi frowned suddenly, he didn't expect this. It's just that I didn't learn chemistry well and forgot the principle of thermal expansion and cold contraction.

Under the high temperature, even the cement wall tiles will be burned to the brimble. It's also normal to burn into cracks!

"Go check it out!" Wei Changfeng immediately asked people to lead the way.

Really. In one place on the city wall, I saw cracks like the back of a turtle, crisscrossing and criss-crossing. Not far away, there is a doorway opened by mutant rats. If this piece is completely shattered, the entire base will be like a hole, and the army of mutant rats will flood in.

"Let the fire be extinguished!" Wei Changfeng was shocked, but he couldn't be surprised at the moment, and hurriedly asked someone to extinguish the fire. Otherwise, if you continue to grill, the crack will only get bigger and bigger.

"Also, let the masons repair this place immediately, and the gap on the side is also strengthening the blockade."

The gap has already been filled, but Wei Changfeng needs him to consolidate it again. Lest the cracked walls affect the gaps and leave hidden dangers!

"Commander, what are you going to use to extinguish such a big fire?" Li Yi asked, but in his heart, he was ready to break the city wall and fight in the alley with the mutant rats.

"Artificial rain!"

Li Yi had long heard of artificial rainfall, and the principle used was nothing more than to lower the temperature of the clouds so that the water vapor in the air reached the dew point in advance.

I just know it, but I really don't know how it works.

Soon Wei Changfeng asked people to bring a box of things, and when they opened it was a cannon barrel similar to a bazooka, and there were two shells on the side. Apparently this is the device of artificial rainfall!

"This is a rain bomb, and it costs 200,000 yuan each." Wei Changfeng saw that Li Yi was curious, so he explained.

"Hurry up and launch." Wei Changfeng said again, time waits for no one, so Wei Changfeng asked them to launch quickly.

"Huh~" adjusted the angle, and the rain bomb whistled away.

"Smack"

The sound was not sensational, but the sky was rapidly darkening, and there were already signs of rain.

The time did not wait too long, after all, the original weather was already drowsy enough, and the sky was already full of clouds, and the rain bombs only accelerated them.

"Wow-"

The rain fell suddenly, without a hint of premonition. Li Yi was drenched, originally thought that it would take a little time to brew, but he knew that he would go down directly.

"That's it!" Wei Changfeng smiled, but the rain fell on his raised face, but he was smiling.

"Let's go to the city." Li Yi shrunk his body, it was still a little hot, but after the rain fell, the coolness followed. The sudden change from hot to cold is so fast!

Back in the city, Li Yi picked up the clothes he had thrown away before and put them on, and he suddenly warmed up a lot. There were also shelters from the wind and rain in the city, but Wei Changfeng did not hide directly, but leaned on the edge and looked towards the heel of the city wall.

The flames under the city gradually decreased in the heavy rain, and the corpses of the mutant rats below were also burned out of shape, and the previous fire was very large, many mutant dead rats were burned to ashes, and only the bones remained on the top surface, and only the bottom color retained the intact corpses. The city wall is half a safe height, and at least for a while, the mutant rats will not be able to attack.

The fire gradually became smaller and gradually extinguished. The temperature in the air has also returned to its original state, even a little lower than before. The rain continued to fall, and it did not stop because the fire was extinguished. The yellow dirt outside the city gradually became muddy because of the rain and the feet of mutant rats.

The mutant rats attacked again, and hundreds of mutant rats tentatively stepped forward. Although the ground becomes muddy and difficult to walk, the soldiers' vision is also blocked. Both sides have their own advantages and disadvantages, even if the humans ask the mutant rats to postpone the battle, I am afraid that the other party will not agree.

Wei Changfeng had no choice but to force the war, but he ordered: "Now there are only a few hundred mutant rats, the number is not much, and the scale is not cheating." Save bullets and make sure you can shoot and shoot again! ”

However, the vanguard is only tempting, but with the wisdom of the mutant rat, they don't know what they want to test. So when the tentative mutant rats are about to destroy the light, the other mutant rats are also on the way.

Patches of mutant rats pressed down, and the soldiers stopped saving bullets, and the machine guns began to fire. The human voice is inaudible, and if you don't listen carefully or get closer, you can't hear it at all.

"Captain!" At this moment, Kang Weilong returned, followed by a man.

This person Li Yi has seen it, it is Long Shengrui, who has met once as a waiter in the world that day.

"Sheng Rui, how is the research in the laboratory?" As soon as they met, Wei Changfeng couldn't wait to ask Long Shengrui, and even ignored his first-class henchmen.

"Uncle Wei, the experiment can only be regarded as a semi-success." When Long Shengrui saw Li Yi, he greeted him with a smile, and then replied to Wei Changfeng.

Li Yi didn't expect Long Shengrui to be involved with the laboratory, and he knew a little bit about the laboratory in the base. If there is anyone who is the core of the entire base, it must be this laboratory, which gives the people of Rao City hope to live. If there is no such laboratory, and there are no talents in the laboratory, no one will be able to develop new research and development, even if the country sends over new research and development.

If the army is the king of this base, the laboratory is like the king's right-hand man. Even the status is higher than that of the army, and there is no doubt that if the Grim Reaper is supported by the laboratory, even if he overthrows Wei Changfeng, it is possible to establish himself as king.

No wonder Long Shengrui's status is so high, it turns out that he has such a relationship. Li Yi also understood Qin Peng's attitude at the beginning, but who was Long Shengrui in the laboratory?

This is purely out of curiosity, after all, no matter what Long Shengrui's identity is, it has nothing to do with him!

The topic over there didn't stop because Li Yi opened a small guess, and Wei Changfeng asked curiously, "Semi-successful?" What do you mean? ”
