Technological Empire of the City

To launch a counterattack against the monster beasts, it is necessary to accumulate strength. Chenjin robots have been manufactured in large quantities, and the assembly line operation makes the speed very fast. A Chenjin robot quickly fills the laboratory warehouse.

Every Chenjin robot is equipped with a Chenjin knife, but it still won't work. Zhang Yu knows that without long-range attack ability, it will be very disadvantageous in the face of fast orcs. There are so obvious weaknesses.

"Teacher, why don't you add an electromagnetic gun to the Chenjin robot." Shi Xi suggested.

"The battery energy is not strong enough to increase the lethality of the electromagnetic gun, and it cannot deal with the thick skin of the orcs." Zhang Yu shook his head and explained.

"What about energy weapons?" Xu Bodao.

"It's the same, these won't work unless the upper limit of battery energy is breached. The skin of the alien orcs is comparable to steel, unless you use weapons of mass destruction - nuclear bombs, which may be useful, but in this way , will also accidentally injure the Chenjin robot." Zhang Yu frowned.

After hearing the words, Shi Xi and others were all troubled, but Shu Qiaoqiao had an idea and said, "Teacher, if you use needles as weapons, what do you think, it's like the rainstorm pear flower needle of the power of martial arts films, as long as you use needles as weapons, what do you think? The needle is sharp enough to pierce the skin of the Orcs, right?"

"The idea is very good, but it is clever, the lethality of the needle is very small." Shi Xi reminded.

"No, I think it makes sense. Although the lethality of the needle is very small, its penetrating power is very strong. We can add a strong poison to the needle. For example, the corpse of Xiang Liu The wreckage, it's useless to keep it anyway, just use the waste." Zhang Yu smiled sinisterly.

"Good idea, let's get started." Shi Xi and the others were suddenly stunned and couldn't wait to say.

As for the use of poison needle weapons, whether it will hurt Tianhe or not, Shi Xi and the others don't care. Anyway, the enemy has gone to live alchemy. What about using poison needle weapons?

The transformation of the poison needle weapon does not require a lot of changes at all. It only needs to make the launching device of the electromagnetic gun smaller and make the bullet become a poison needle. The transformation is completed easily, and the transformed electromagnetic gun is lighter and smaller. some.

The transformation of the poison needle is a little more troublesome. It is necessary to add the powder of the Xiangliu wreckage into it, but it is found that this is very wasteful. When the poison needle is shot, the powder will fall, because the poison needle is flying too fast.

Therefore, it was changed to melt the powder in water, and then soak the poison needle in it, wait for the poison needle made by Chenjin to absorb the toxin, and then take it out to dry in the shade. After that, it becomes a poison needle, Chenjin poison needle. There are toxins in it.

A week later, all the mountains in the poisonous forest were excavated, and all the Chenjin inside was hollowed out. A total of 10 million Chenjin robots were built, and then Zhang Yu became depressed because the investigation found that the alien beast's The number is hundreds of millions of times that of Chenjin robots.

"No, the strength is not enough, we must find more Chenjin, so that when the war begins, we can have enough strength to fight against the large number of orcs." Zhang Yu was very worried.

"But where to find Chen Gold Mine, and there are orcs outside the poisonous forest, we can't get out." Shi Xi said helplessly.

"Yeah, teacher, or take it slow, it's okay to get rid of some of the orcs first." Xu Bo suggested.

"I think too much, I ask you, if your opponent has a weapon like the Chenjin robot, would you like to see the enemy have more." Zhang Yu asked back.

"Of course not." Shi Xi and others blurted out their debut.

Immediately, Shi Xi and others fully understood that if the orcs knew that the human race had so many Chenjin robots, and they were so powerful, they would definitely join forces to eliminate this unsafe factor.

Therefore, when the strength is not enough, you must not expose the fact that you have Chenjin robots. Otherwise, the consequences are already doomed, that is, the poisonous forest is surrounded and attacked by trillions of orcs, and they are not afraid of death, because the orcs do not It is possible for the human race to rise, just like in the past, it is impossible for the human race to let the beast rise to become the master of the earth.

Since the Chenjin robot cannot be activated for the time being, because the numerical advantage is not large enough, it can only continue to increase its comprehensive strength, and finding the Chenjin mine is the fastest way and the best way.

After thinking about it, Shi Xi and others realized it and said, "Teacher, what should I do?"

"It's fine for me to find Chen Gold Mine by myself. You stay here to mislead the orcs outside and make them think I'm still here. Otherwise, I'm afraid that my actions will be hindered, which will be troublesome." Zhang Yu ordered.

"Are you going alone? It's too dangerous. Bring Yas and the others. They are all members of the expedition team. Even if they are not strong, their survivability is the best." Shi Xi suggested worriedly.

"No, there are so many people, it's hard to avoid the orcs, I'm the most suitable person." Zhang Yu shook his head and said.

"Okay, then teacher, be careful." Knowing that they could not persuade Zhang Yu, Shi Xi and others agreed.

After cleaning up, when Zhang Yu was about to leave, Song Bao and Zhang Yue came running. They learned from Shi Xi that Zhang Yu was leaving, so they rushed over and finally stopped Zhang Yu. It made Zhang Yu very helpless, because Zhang Yu didn't plan to take anyone with him at all.

"Dad, you want to leave me again, right?" Zhang Yue's face flushed with anger.

"That's right, Brother Yu, it's not right for you to do this. What is our relationship? We share blessings. Of course we have to be together when we are in trouble. Needless to say, add me and I will go wherever you go." Song Bao said righteously.

"I don't dare, I want to be with you wherever you go anyway." Zhang Yue said spatly.

Zhang Yu, who sighed, said speechlessly: "Please, if you can be stronger, I will take you there, but if you are so weak, taking you out can only hinder me. You should stay and practice hard."

"But, but~". Zhang Yue wanted to defend himself with a face full of reluctance, but found that the defense was indefensible, because it was a fact, and there was no human rights if the strength was weaker.

After the impulse, Song Bao calmed down and smiled bitterly: "Yes, it is a little weak, and I will hinder you, Brother Yu, but next time, it will definitely not be like this, we will practice hard."

"That's the best, then~". Zhang Yu, who was just about to leave, was interrupted by Zhang Yue: "Dad, let me go into the small universe inside your body. You can let me out when there is no danger. I'll follow you anyway."

Seeing the resolute expression on his daughter's face, Zhang Yu also knew that he had neglected his daughter a little since he was a child, so he softly agreed: "Okay."

It doesn't matter if I promise, anyway, I don't remember it soon, it's impossible to let my daughter out, there is no dangerous thing, it doesn't matter if I promise, and after that, I can use the road to be very dangerous to prevent my daughter from coming out. Excuse, perfect.

Song Bao didn't join in, because he couldn't cultivate after entering the small universe in his body, so he stayed to cultivate, and when his strength became stronger, he could justifiably help Zhang Yu, which would be better.

"I'll leave it to you here." Zhang Yu bid farewell to Shi Xi and Song Bao and the others, left the poisonous forest, and his daughter Zhang Yue was also taken into the inner universe.

"it is good". Shi Xi and his party responded and watched Zhang Yu leave.

After returning to the villa of Xingyueguo, Zhang Yue and her mother reported their whereabouts, and they have already said everything Zhang Yu has done, until when Zhang Yu promised not to be dangerous, let yourself go out to Zhang Yu. Adventure together.

"Pfft". Tang Yan smiled and said, "Xiao Yue, you were deceived by your father, whether it is dangerous or not, it is actually your father who has the final say."

"That is to say, Dad didn't think at the time that he would let himself go out on an adventure with him." Zhang Yue was full of anger.

"It must be, you are so clingy, how could your father let you out." Angela teased.

"Hmph, I won't pay attention to my father again." Zhang Yue shouted angrily and ran back to his room, the one who couldn't coax well.

I didn't know that Tang Yan and the others had debunked Zhang Yu's plan, and was disliked by his daughter. He was tiptoeing to the edge of the poisonous forest. blocked.

The dense number of alien beasts also blocked the way out. Even if it is invisible, it will inevitably touch the orcs. At that time, it will definitely attract the dragons and phoenixes, which is even worse, so Zhang Yu plans to use wisdom. escape.

"The ground is blocked, but the underground will never be blocked, so just leave the underground." As soon as Zhang Yu rolled his eyes, he had an idea.

From the underground of the poisonous forest, it is not very difficult to dig a hole leading to the outside, because Zhang Yu has a small universe in his body, and he didn't put all the soil that he didn't need in, so he dug a hole quietly. Out.

Without making any sound, a tunnel led from the bottom of the alien orc encirclement to the outside world. Just in case, Zhang Yu dug a distance of dozens of kilometers, which greatly reduced the chance of being discovered.

In the dark tunnel, the eyes with night vision helped a lot, so that Zhang Yu did not dig in the wrong direction and digged under the feet of the alien beasts.

"almost". Zhang Yu was delighted and kept digging the cave.

The soil collected into the microcosm of the body is all turned into soil resources and collected. These aura-filled soils can be used to grow potted plants, and can also be used to grow the treasures of the four-dimensional world. wasted.

Deep underground, Zhang Yu didn't know where he was digging, he just digged by feeling.

"Crack".

After a large mass of soil was collected, a huge cave appeared in front of Zhang Yu out of thin air, and Zhang Yu was a little dumbfounded, because there were traces of human life left in this huge cave.

"A lot of secret passages". Immediately, Zhang Yu found dozens of secret passages in the huge cave. ..
