Technological Empire of the City

Next to the poisonous forest, Zhang Yu, who started to develop products to resist poison gas, felt the stone devil, touched the contract signed, and was tortured by the power of the contract, and suddenly showed a disapproving smile. The stone devil thought too much, how could he be Died in the hands of the mere dragons.

"Perhaps we can force more alien beasts to sign contracts to protect the human race." Zhang Yu was thinking about this good solution, but there is no way to implement it for the time being. He can only put it aside and try his best to develop products that resist poisonous gas.

The poisonous gas in the poisonous forest has a very complex composition. It has biological toxicity, physical toxicity, and even strange poisonous energy, which together attack any creature that approaches. If you want to resist the poisonous gas, you must resist all the characteristics of the poisonous gas at the same time.

Therefore, the developed products must be taken orally to suppress the biological toxicity and strange toxic energy of the poisonous gas. As for the toxicity of the body, it can also have resistance at the same time, which is much better than the resistance drugs applied externally. After all, the drugs applied externally , can only defend the body surface, not the internal organs.

Take out a lot of various grasses picked up in the four-dimensional world. Grass is sometimes medicine. The easiest way to develop medicines is to fight poison with poison. The most difficult thing is to completely detoxify. Choose one of the two options and choose the attacking poison with poison scheme.

"When there is more time in the future, we will develop a complete detoxification plan." Zhang Yu sighed and started the research and development of mixed poisons.

The members of the dragon clan who blocked all the exits of the poisonous forest thought they had not been discovered by Zhang Yu, but unfortunately, although their dragon might was very weak, they were still discovered by sensitive alien beasts, so Zhang Yu also discovered their lurking.

The Dragon Clan never thought that there would be alien beasts around Zhang Yu, and was overwhelmed, revealing the information of Long Wei, and Zhang Yu knew that the Dragon Clan was coming, and the plan to sneak attack was impossible.

Waiting left and right, the dragon clan members found that Zhang Yu refused to leave the poisonous forest, as if he wanted to stay in that place and never come out for a lifetime, which made the dragon clan members very irritable, but they did not dare to take risks easily Close to the poison forest.

"Damn, why won't you come out? That human doesn't come out. How can we sneak up on him, catch him, and kill him." Longhou Ao Huang vented impatiently.

"Be patient, maybe that human is just where he recharged his energy, so he stayed a little longer. It doesn't matter if he waits for two or three days. Anyway, we all guarded the exit, and he can't escape." Long Hou Aozhi comforted with a smile on his face.

"That's right, then wait, he will come out." Longhou Ao Huang was stunned, lying on the ground and resting, but his mind was on the embankment, ready to deal with Zhang Yu at any time.

Dragon Palace, Dragon King Ao Ying waited, half a day passed, no news at all, a day passed, still no news, this made Ao Ying very upset, it has been so long, even if Zhang Yu became stronger, he was also caught That's right.

"Come on, ask what's going on and why that human hasn't been caught yet." Dragon King Ao Ying roared.

"Yes". The Dragon Palace guard responded and went to contact Ao Huang on the front line to wait for the dragon.

Soon, the disappearance was communicated back, and then the Dragon King Ao Ying knew that it was Zhang Yu who hadn't left the poisonous forest and didn't catch him, but when Ao Huang waited for Long to answer, he would definitely not let Zhang Yu run away again.

"Really, then wait a little longer, Zhang Yu is already a turtle in a urn anyway." Dragon King Ao Ying muttered happily with a face full of joy.

It's a pity that the idea of ​​the dragon family is going to go bankrupt. Zhang Yu has no thoughts and ideas to leave the poisonous forest at all. He is dedicated to developing mixed poisons to resist the poisonous gas of the poisonous forest, various venoms brought from the three-dimensional world, and in the dragon world prison. , The poisons found in the Sun and Moon Continent were mixed together.

A brand new super-poison was formed. The mouse became a test product. It was injected with a new type of mixed poison, and then put into a glass jar full of poisonous gas. Zhang Yu observed the reaction of the mouse. At first, The mouse's body was still fine, but after a few minutes, the mouse suddenly turned into a pool of blood.

"how come". Seeing this scene, Zhang Yu was stunned, and quickly put the mouse, which had turned into a pool of blood, into the detector. Through the magnifying glass, he saw that the cells of the mouse had all been ablated.

Zhang Yu analyzed that it may be because the mixture of poisons is not stable enough that the poison and gas in the mouse collapsed. The combination of the two caused the mouse to instantly turn into blood. It’s a pity, it’s about to succeed. .

"Go ahead."

Cheering himself up secretly, Zhang Yu continued his next R&D work.

The ingredients of various poisons were differentiated to the finest detail by Zhang Yu. The ingredients of each poison were blended together according to the optimal ratio, and then fully stirred with a centrifuge, in order to make the mixture of poisons more stable.

Finally, a bottle of dark black mixed poison was held in Zhang Yu's hand, and he carefully observed the poison with his eyes. When the poison stopped bubbling, Zhang Yu started the mouse experiment.

After filling the medicine and throwing it into the gas tank, the movements were done in one go. The mouse screamed in terror and ran wildly in the gas tank. A few minutes later, the mouse was still safe and sound.

"Is it successful?" Zhang Yu is not sure, after all, there is too little time, unless he can try it with his own body.

After thinking for a moment, Zhang Yu felt that he would try it himself. After all, if it didn't work, there was also a real fire of the sun, which could burn off all the toxins in the body. It was just a little burn, and it would soon recover.

"Guru~".

After swallowing the mixed toxin, Zhang Yu ran out of the lab, and his skin turned black under the attack of the mixed toxin. When he ran into the poisonous forest and the poison gas enveloped Zhang Yu's body, the uncomfortable feeling disappeared.

A delicate balance appears in the body and the body. It should be the antagonistic effect of the mixed toxin and the poisonous gas. The two do not give way to each other, but no one can gain the upper hand. However, when the mixed toxin is not supplemented by external force, Zhang Yu It was found that the mixed toxin was defeated by the poisonous gas, and the time was one hour.

"not good".

With a cry of exclamation, Zhang Yu ran out of the poisonous forest, but there was no poisonous gas package. The mixed toxins began to invade Zhang Yu's body, and the skin began to turn black again. Zhang Yu turned and returned to the poisonous forest. The mixed toxins retreated and the skin recovered. , but the poisonous gas of the poison forest began to invade Zhang Yu's body.

Whether leaving the poison forest or standing in place, Zhang Yu will be attacked by poison.

"Enough data collection, let's get rid of toxins". Zhang Yu murmured with a wry smile, and activated the true fire ability of the sun.

"boom".

The bursting flames came out of the body, and the toxins were burnt up, but Zhang Yu's clothes were also burnt out, and the skin was dry, cracked and charred. He quickly left the poisonous forest and turned off the real fire of the sun. Zhang Yu vomited hot gas, I was relieved, every time I used Sunshine Fire, it was an act of self-harm to myself, but Zhang Yu couldn't refuse.

Back in the humble laboratory, Zhang Yu said with bright eyes: "The mixed poison is successful, the next step is to delay the duration of the mixed poison, and the antidote has been researched, otherwise, not everyone will have their own real fire of the sun and burn them out. toxins in the body".

When the effect of the poison is over, it will inevitably lead to a dilemma. If you leave the poison forest, you will be poisoned by the mixed toxin. If you don't leave the poison forest, you will be poisoned by the poisonous gas of the poison forest.

Zhang Yu kept records of every ingredient in the mixed poison, and then extracted the antidote using herbs with the opposite composition of the poison.

To prolong the time of the mixed poison, it is necessary to use biological toxins, and the creatures can multiply, which can extend the mixed poison for more time.

"start". Zhang Yu shouted excitedly, and couldn't wait to start research and development.

At the same time, in the Xingyueguo No. 1 villa in Zhang Yu's body, the birthday party has passed, but Zhang Yu has never come back, which makes Tang Yan and others very angry, and the eldest daughter Zhang Yue is even more chanted.

"Bastard dad, it's too much to even come back for his son's daughter's birthday."

With a wry smile, although Tang Yan was also very angry, he couldn't let Zhang Yu lose points in front of the children, so he comforted: "Maybe your father has something important to do, so please forgive him once, okay?"

"No, I have forgiven him many times, but the result is still the same." Zhang Yue was dissatisfied.

In the hall, Zhang Yu's children, Zhang Kewei, Zhang Lixuan, etc., shouted resentfully.

"That's right, don't forgive Baba."

"I don't like Baba anymore."

"Baba is bad."

"---".

"Hehehe~". Zhang Qiang and Zhao Yan, the elders, smiled bitterly. This time, their son Zhang Yu was indeed a bit too much, and it was not easy for them to speak for Zhang Yu.

Outside, Zhang Yu: "Ah... sneeze, ah... sneeze".

Touching his itchy nose, Zhang Yu didn't care if he was being talked about by someone. Shuangyang stared at the experimental table, the newly developed mixed poison. At this time, the mixed poison was dark red and thin. It looks like it will still move.

This is biological poison. If there is no antidote, it will multiply in the body of the organism, and finally become a hotbed of biological poison, and it will not die until it encounters the air.

"Gollum".

After drinking the mixed poison, Zhang Yu couldn't wait to walk into the poisonous forest. He closed his eyes and felt it. He found that the mixed poison in the body and the poisonous gas from the outside had formed a stable equilibrium state. The mixed poison broke out, Zhang Yu drank the antidote, and the biological poison was eliminated.

After perceiving his body, he found that nothing happened. Zhang Yu said with ecstasy, "I succeeded."

But there was no one around, and the joy of success could only be enjoyed by himself. Zhang Yu finally bred a large amount of mixed poison in the laboratory, and then put away the simple laboratory, entered the poison forest, and completely disappeared in the In the induction of the dragon shark.

The dragon shark leader who surrounded the poisonous forest shouted with a mad face: "No, that human breath has disappeared in the poisonous forest."

"What, how is this possible". After hearing the words, Ao Huang, the Dragon Marquis, waited for the dragon and roared in surprise. ..
