Technological Empire of the City

The robots that attacked the killer vines did not have the flesh and blood sucked by the killer vines. The killer vines that could not get nutritional supplements on the robots had to prey on the creatures from the worm star, so the residents of the worm star suffered.

After getting nutrients from the insect star, the killer vine's cane grows quickly again, and the cane that was frozen and broken by the robot grows out in an instant, and the growth rate is faster than the speed of the robot to destroy the cane.

Soon, the robot not only did not move forward, but was slowly forced back by the fast-growing cane. The two sides were in a stalemate. The robot quickly reported the situation to Zhinao, and Zhinao Xiaowen quickly reported it to Zhang Yudao.

"Brother Yu, the growth rate of the killing vine has suddenly accelerated, and the speed at which the robot can destroy the killing vine can't keep up with its growth."

"Damn, the killer vine will definitely **** a lot of nutrients from the other side of the wormhole. This is bad." Upon hearing this, Zhang Yu instantly analyzed the reason.

If the killer vine cannot be eliminated as soon as possible, the killer vine will grow again in the cracks around the building. The cracks are passed through the walls by the rattan, which will cause the building to cause another damage, and the building will definitely collapse by then.

"Teacher, the engineering robot has a drill, let it get in and close the door to the starry sky." Shi Xi suggested.

"It won't work. In the underground plaza, the gravity near the gate of the starry sky must be very strong. Once the robot gets there, it will definitely not be able to move. How can you close the gate of the starry sky?" Upon hearing this, Zhang Yu dismissed Shi Xi's suggestion.

"Teacher, how about injecting a lot of liquid nitrogen gas into the underground plaza." Xu Bo thought hard for a long time and suggested.

"Well, you can try it." Zhang Yu heard the words and nodded in agreement.

"Then I'll make arrangements." When Xu Bo heard his suggestion accepted, he immediately responded with joy and went to work.

"---". Shi Xi and others immediately looked at Xu Bo who was busy with envy, and they also wanted to prove themselves in front of Zhang Yu.

Under Xu Bo's command, several robots dragged a huge tube into the headquarters building, and when they came to the corridor leading to the laboratory, the robot pushed the tube out and stuffed it into the gap in the rattan.

At the other end of the tube, it was connected to a huge liquid nitrogen tank on the street outside. After Xu Bo received the signal from the robot, he immediately opened the gate of the liquid nitrogen tank, and immediately, the liquid nitrogen gas was transported through the tube. Go inside the building.

In the corridor outside the experiment room, gas was ejected from the outlet of the pipe, making a sound of "Sisisi". Because of the high density of the refrigerated gas, it descended and floated all the way into the underground square.

The killer vine's vines slowly began to freeze, and the killer vine's burl felt the rapid change in temperature, and quickly found the source. In an instant, the killer vine controlled the other vines and desperately blocked the corridor of the laboratory.

"Sisisisi".

The freezing gas froze the rattan, sticking the rattan tightly together, but also sealed the crevices of the rattan. The freezing gas that could not pass through the laboratory emerged from the lobby of the building, and the frost was in the air. On the ground and the walls, layer after layer was formed.

On the street, seeing the frozen gas coming out, Zhang Yu stopped Xu Bo and said, "Stop it, the frozen gas can't enter the laboratory anymore."

"how so". After Xu Bo turned off the air-conditioning tank, he was confused.

"Think of other ways." Zhang Yu sighed.

"---". Shi Xi and others thought hard.

There are thousands of ways in my mind, but there is no one that can successfully eliminate the killing vine without destroying the headquarters building. The killing vine, which is supplemented by the creatures in the insect planet, can grow continuously.

Therefore, the nutrient source of the killer vine must be cut off, and then the killer vine can be slowly cleaned and eliminated. But how to close the door of the starry sky, Zhang Yu hasn't thought of a good way to do it, and the indecisive Zhang Yu looked aside Two-headed dragon.

Heilong was stared at by Zhang Yu, shaking his whole body, and shouted: "I can't do it, I can't beat that plant monster."

"Neither can I". Honglong's face turned white, and he hurriedly shrugged.

"Initially there was no hope for you." Zhang Yu despised.

"Will you be able to speak, you will die if you are tactful, it hurts too much". The two dragons were embarrassed and turned their heads bitterly.

Looking at the two dragons, Zhang Yu suddenly remembered that he still has a little brother, the plant guardian-a small sapling. As a magic plant, it should be able to close the door to the starry sky without disturbing the killing vine, and the small sapling It should still be in the laboratory now.

Thinking of this, Zhang Yu said with joy, "I have a way."

"any solution". Shi Xi and others asked curiously.

"Niannian, hurry up and wake up." Zhang Yu didn't answer, but lightly patted his jacket pocket.

After waking up, the elf Niannian yawned and said uncomfortably: "What's wrong, don't you know I'm sleeping?"

"If you are in a hurry, please contact the young sapling in the laboratory. If I want to let it do it, hurry up." Zhang Yu urged.

"Ok". The elf thought and answered.

The little fairy Nian Nian, who was eloquent, quickly got in touch. The little saplings playing in the laboratory, the little saplings with magical powers, were not affected by the freezing gas, and plants naturally have a good impression on the saplings, let alone Will hurt it.

On the street, the elf looked at Zhang Yu and said, "I got in touch, what should I do next."

"Let the young sapling follow the passage to the laboratory and return to the underground square." Zhang Yu ordered.

"understand". The elf nodded Niannian.

After hearing Zhang Yu’s conversation with the elves, Shi Xi and others finally understood what Zhang Yu’s method was. I have to say that this method is the most labor-saving. As long as the door to the starry sky is closed, the killer vine, which has no source of nutrition, is just The meat on the chopping board is nothing more.

"The teacher's idea is still so eclectic, and this method can be thought of." Shi Xi admired.

"Hmm". Xu Bo and others nodded wildly, agreeing.

In the laboratory, the grove gently danced the leaves, the roots squirmed, and walked towards the underground plaza. The young saplings that came to the Xingyue Institution for so long have only been to the underground plaza and the laboratory, so they didn’t leave. Wrong way.

On the way, the young sapling bumped and bumped. I don’t know how many times it has hit the killer vine, but the killer vine in the corridor did not show any dissatisfaction. Let the young sapling be on his own. walk around.

It took a long time for the young sapling less than one meter to reach the end of the passage. In the underground plaza, Zhang Yu was the commander. The young sapling quickly found the energy equipment to supply the Star Gate.

On the street, Zhang Yu couldn't wait to say: "Niannian, quickly let the young sapling press the red button on the panel."

"I know". The elf replied, using magic to contact the young sapling.

In the underground plaza, the young saplings who can only perceive the world with magical powers do not know which button is red. The hesitant young saplings waved their branches messily and the leaves rattled.

In the street, the elf Niannian relayed the words of Sapling: "Brother Yu, Sapling said it doesn't know which button is red."

"Oops, I actually forgot that the young sapling is invisible. By the way, you can ask the young sapling to pull the cable away. The cable is stuck on the device and can be easily pulled away." Upon hearing this, Zhang Yu quickly changed his way of thinking.

"Ok". The elf replied, and informed the young sapling.

In the underground square, the young tree sapling sensed it and found the cable under the equipment. The small, hard tree branch was wrapped around the cable, and then it was pulled hard. With a soft sound, the cable was separated from the energy equipment. .

"Zizzi".

The electric arc flickered on the starry sky gate, and then it went out. The starry sky gate without energy supply also slowly stopped operating. I saw a stable wormhole and began to collapse. It was too late to take back the killer vine of the rattan, and lost it. Most of the rattan.

"Shoo, hoo,".

The furious killing vine, waving the cane, made a loud "bang, bang" when it hit the ground and walls, turning the surrounding area of ​​the underground square into a mess.

The frightened young sapling hurriedly hid behind the starry sky gate, the murderous vine that became angry, but the six relatives did not recognize it, no matter how strong the plant affinity was, it didn't work, and the starry sky gate of unknown material was not afraid of the killing vine's impact.

"Wow!" The young sapling trembled with fear, and the leaves trembled.

On the street, the elf Niannian hurriedly said: "Brother Yu, the young sapling has succeeded. Now the killer vine has gone mad. It asks you to save it."

"I know". Zhang Yu said in ecstasy, and told Zhi Nao: "Xiao Wen, let the robot attack."

"Yes". Wisdom Xiaowen responded.

The killer vine without a source of nutrition can no longer recover quickly after being crushed by the robot's freezing of the rattan. The violent killer vine whipped the robot, drawing dents on the robot.

The painless robot attacked the Murder Vine regardless of his recklessness. The Murder Tang, who began to retreat, was soon chased by the robot and came to the underground plaza. The huge tree tumor was inconvenient to move and became a burden.

"Sisisisi".

The robot surrounding the killing vine activated the freezing gun, and a large amount of freezing gas was sprayed on the tumor of the killing vine, and it slowly condensed into the icy tree tumor. The rattan also lost its vitality and was motionless. The robot was allowed to break it.

On the street, Zhinao Xiaowen reported good news: "Brother Yu, the killing vine has been wiped out."

"Go, go in and see how big our losses are." Hearing this, Zhang Yu couldn't wait to say.

The group of people entered the headquarters building. The messy scenery made Zhang Yu's face unsightly. After arriving in the underground plaza, the young tree sapling squirmed out quickly and hugged Zhang Yu's calf, obviously frightened.

"Okay, don't be afraid". Zhang Yu stroked the leaves to appease.

Looking at the underground square that seemed to have been destroyed by the earthquake, Shi Xi said helplessly: "It seems we are going to rebuild the headquarters building."

"I think so too". Xu Bo and others agreed with gloomy faces.
