"The green solution is dissolved by a hundred evolutionary zombies. I named it the source of the etch. The raw material is the gastric juice of the giant black squid. The gastric juice will mutate after it dissolves the zombies. It is suspected that the virus reacts with the gastric juice. The more the virus, The greater the reaction, theoretically, that can cause absolute damage to the D2 zombies, but the skin bones of D3 can effectively resist this impure source.

I tried it again and again, and I couldn't refine it again. Even if I used the type 2 zombies as raw materials, we got an S3 zombie... ”

Zhang Xiaoqiang listened to Xu Jing’s remarks. He heard Xu Jing’s S3 zombies. Some doubts, the only one S3 was collected by doctors. It is said that the research value is greater than the D3 zombies. How could it be obtained by Xu Jing?

"You said it was S3? Is the doctor willing to give you the body of S3?"

Zhang Xiaoqiang can't understand what the doctor is doing. The doctor got the S3 pledge to say that there will be breakthrough results. Is the doctor's research successful? But why didn't you report it to him?

"Do doctors also have S3? What am I getting live?"

Xu Jing was asked to be confused. The doctor had a S3 zombie body. She really didn't know, and she went to the doctor to take the body back for research.

"Wait... I was confused by you. You said that the S3 you got is alive, but as far as I know, S3 has only appeared once, that is, the mysterious zombies that make the whole gathering place uneasy, you again Where did you get it?"

Zhang Xiaoqiang had to figure out this with Xu Jing. What do you mean by a living S3? The last time Zhang Xiaoqiang personally shot, there are four evolutionists in coordination, five evolutionists can only repel the S3 zombies, still dead, and finally rely on the police ambush to kill the S3, for no reason Xu Jing got a living, he couldn't believe it anyway.

"What is giving me is alive, the limbs are cut off, sent from the other side of the river, as if the soldier who sent the zombie said that it was caught by the serpent..."

Xu Jing said this, Zhang Xiaoqiang understood, it was the zombie with a blue color. It is said that the zombie could not stop even the puppy and Yang Keer, or the mutant snake bite, or die under its claws. It’s not just three people, but thirty people are all possible. Zhang Xiaoqiang didn’t take it seriously, thinking it was S2.

"Can you be sure? Is it really an S3 zombie, will it be close to S3?"

Zhang Xiaoqiang was not sure, Xu Jing nodded and said:

"I'm sure that the zombie's virus is ten times more than the S2 zombie, the S2 zombie is five times the S-type zombie, and the S-type zombie is..."

"Stop, don't explain, continue the topic just now."

Zhang Xiaoqiang interrupted Xu Jing, and his heart was horrified. The zombie who sneaked into the gathering place last time was not S3, but S4? At S4, the zombie's skin turns white and knows how to disguise. The speed can exceed his dynamic vision in a short time. The speed of the S3 zombie should be only twice as fast as that of the S2. It is similar to the curtain Pepe, knowing that the S2 zombie still Not enough to touch Zhang Xiaoqiang's dynamic vision. Obviously, the doctor won the grand prize. The legendary S4 is also the first type 4 zombie that Zhang Xiaoqiang killed. Of course, this is not good news, the S4 zombie came out, D4 type. Will the zombies be far behind?

"By dissolving the virus in the S3 zombies, we obtained a pure solution of etched source. The power of this solution is more than ten times that of the big fish stomach juice, and it is more pure than the big fish's gastric juice.

Has been tested, can melt the bones and skin of D3, in addition, can dissolve most of the organic objects, slow down the dissolution of the soil, but the purity requirements are very high, once added to other magazines, it will Reduced to gastric juice.

In addition, the source of the erosion is also lossy, and it will lose a certain proportion when dissolving D3. On the hardest bones and outer armor of the zombies, the loss is obvious. I just used the only source to corrode D3, and the recovery ratio is only a hundred. Forty points, according to the size of the zombies, should be more than 120% to more than 150%.

Therefore, in order to manufacture on a large scale, it is necessary to use a large amount of S3 and S3 to dissolve one at a time, and the source of corrosion that can be obtained can be increased by at least 60%. ”

Xu Jing’s remarks made Zhang Xiaoqiang have the most intuitive understanding of the so-called eclipse. This is a baby, but the restrictions are high. You must use the type 3 zombies as fuel to get more sources of erosion, but In use, when encountering a hard object, there is a loss, and care must be taken to avoid the addition of impurities.

Zhang Xiaoqiang and Xu Jing’s question and answer, Wen Wen listened to the ear, Wen Wen thought that the cat’s claws were scratching. He was eager to get an eclipse source. As a weapon to deal with the type 3 zombies in the future, let him fight this afternoon. Losing confidence in the high-level zombies, even the skin can not break, how to develop his natural selection in the future, to know that their goal is to become the pinnacle of the world, not as a mouse.

"The eclipse source in your hand can make two copies. You may use the ground tomorrow, plus the red arrow. If you are lucky, you can't clean up the remaining D3s."

Zhang Xiaoqiang took the attention of the source of erosion and saw that Xu Jing had a difficult color, and he comforted:

"Don't you say that the best material is S3? Don't worry, no matter how many S3s you catch, one does not give the doctor, all to you, are you satisfied? With S3, you don't want to do much..."

At this time, Xu Jing nodded ~ lightnovelpub.net ~ mind calculation, gave up the source of the hands, in exchange for Zhang Xiaoqiang's commitment, plus she deducted a little from the wall, there are thousands of zombie bodies behind the wall, Using a zombie to extract a portion of the impure source of erosion is enough for her to do other experiments.

Solved the source of the erosion, Zhang Xiaoqiang found Wang Le head.

"Wang Le, today your trebuchet and the burning bottle have made a great contribution. We have won a whole night for us. I will tell you to give priority to your raw material needs.

However, time is still not enough. Can you make more burning bottles in the night, I hope to use all of us to evacuate... ”

This time I changed Wang Le noodle and said it to Zhang Xiaoqiang with a hoarse voice:

"Hey, the gasoline is completely used up, and the rest are all non-movable vehicle reserve oil. If it is really necessary, it can only destroy the traps in the central area. There are incendiary bombs that are being rushed today."

The central area that Wang Le said is Zhang Xiaoqiang's final card, which is the guarantee that he can lead the troops back to the lake. Although Zhang Xiaoqiang will not let his soldiers die, he will not let his troops have too much wear and tear. These soldiers will fight again and again. The basic quality is much stronger than the left-behind units of the base. These soldiers are the capital of Zhang Xiaoqiang's life. Therefore, once it is at a critical moment that cannot be violated, Zhang Xiaoqiang is willing to abandon the entire gathering place and take these forces away.

Wang Le said this, Zhang Xiaoqiang hesitated for a long while, and said to Wang Le:

"Try to collect the used tires and all the things that can be burned in the gathering place, throw them across the wall with a trebuchet, do everything, listen to the fate, don't move the trap."

Just when Wang Le nodded and was ready to go to work, Huang Quan came back. With a few men, he pointed a gun at a burly man and walked to the front. The light illumined the man’s face, but Zhang Xiaoqiang gave it. Wang Bing of the wanted order.
