"That green liquid was purified by dissolving hundreds of evolved zombies. I named it the corrosive source. The raw material was the gastric juice of a giant black fish. After the gastric juice continuously dissolves the zombies, it will mutate. Initially, I suspected that it was a reaction between the virus and the gastric juice. The more the virus, the stronger the reaction. Theoretically, that thing can cause absolute damage to the D2 zombies, but the D3's skin and bones can effectively resist this kind of impure corrosive source.
I tried many times, but I couldn't purify it again, even if I used a type 2 zombie as the raw material. Later, we obtained an S3 zombie … "
Zhang Xiaoqiang listened quietly to Xu Jing's explanation. When he heard Xu Jing mention the S3 zombie, he was a little confused. The only S3 was kept by the doctor, and it was said that the research value was even higher than the D3 zombie. How did Xu Jing get it?
"You said it was an S3?
The doctor was willing to give you the S3's body? "
Zhang Xiaoqiang couldn't understand what the doctor was doing. The doctor had gotten the S3's guarantee that there would be a breakthrough. Could it be that the doctor's research was successful?
But why didn't he report it to him?
"The doctor also has an S3?
What I got was a live one? "
Xu Jing was confused. She really didn't know that the doctor had an S3's body. She wanted to find the doctor and take the body back for research.
"Wait a minute … I'm confused. You said that the S3 you have is alive, but as far as I know, the S3 has only appeared once, and it was the mysterious zombie that caused chaos in the entire colony. Where did you get it?"
Zhang Xiaoqiang had to clarify this matter with Xu Jing. After all, what did a living S3 mean?
Last time, Zhang Xiaoqiang personally fought with four evolvers. The five evolvers could only force the S3 to retreat, and some of them died. In the end, they had to rely on the police's ambush to kill the S3. For no reason at all, Xu Jing got a live one. He couldn't believe it no matter what.
"They gave me a live one with all four limbs chopped off. They were sent from the other side of the river. I think the soldier who sent the zombies said that they were caught by the snake …"
Zhang Xiaoqiang understood. It was the green-colored zombie. It was said that even the puppy and Yang Ke-er could not stop it. It was bitten by the mutant snake. Otherwise, the number of people that died under its claws would not only be three, but thirty. Zhang Xiaoqiang did not think much of it at that time, thinking it was an S2.
"Are you sure?
Is it really an S3 zombie? Could it be close to an S3? "
Zhang Xiaoqiang wasn't sure, but Xu Jing nodded and said,
"I'm sure, that zombie's virus content is ten times that of an S2 zombie, an S2 zombie is five times that of an S zombie, and an S zombie is …"
"Stop. There's no need to explain. Let's continue the topic."
Zhang Xiaoqiang interrupted Xu Jing. He was shocked. The zombie that sneaked into the base was not an S3, but an S4?
When it comes to an S4, the zombie's skin would turn white, they would know how to disguise themselves, and their speed would be faster than his motion vision. An S3 zombie's speed should only be twice as fast as an S2, about the same as Mu Peipei. It must be known that an S2 zombie was not enough to trigger Zhang Xiaoqiang's motion vision. Obviously, the doctor had hit the jackpot. It was the legendary S4. It was also the first type 4 zombie that Zhang Xiaoqiang had killed. Of course, this was not good news. Now that the S4 had appeared, would the D4 be far behind?
"By dissolving the S3 zombie's virus, we have obtained the Source Erosion Solution. This solution is ten times stronger than the stomach juice of the big fish, and it is even purer than the stomach juice of the big fish.
It has already been tested, and it can dissolve the bones and skin of a D3 zombie. It can also dissolve most organic substances, slowing down the erosion of the soil. However, the requirement for purity is very high. Once other substances are added, it will be reduced to gastric juice.
In addition, the Source Erosion also has a loss. When dissolving a D3, a certain amount will be lost. On the hardest parts of the zombie's bones and armor, the loss is obvious. Just now, when I used the only Source Erosion to dissolve a D3, the recovery rate was only 40% higher. According to the size of the zombie, it should be 120% to 150% higher.
So, to mass produce it, we need a large number of S3s. Every S3 that is dissolved can increase the amount of Source Erosion by at least 60%. "
Xu Jing's words gave Zhang Xiaoqiang a direct understanding of the so-called Source Erosion. It was a treasure, but it had high limitations. It needed to use Type 3 zombies as fuel in order to obtain more Source Erosion, and when it came into contact with hard objects, it would be lost. So, it had to be used carefully and not add impurities.
The conversation between Zhang Xiaoqiang and Xu Jing was heard by Wen Wen. Wen Wen's heart felt like it was being scratched by a cat. He desperately wanted to obtain a Source Erosion as a weapon against Type 3 zombies. This afternoon's battle had made him lose confidence in high-level zombies. If he couldn't even break their skin, how could he develop as a Chosen One? Their goal was to be at the top of the world, not to be a mouse.
"Then can you make two portions of the Source Erosion in your hand? Tomorrow, we might use it on the ground. With the addition of the Red Arrow 8, if we are lucky, we might be able to take care of the remaining D3 zombies."
Zhang Xiaoqiang was thinking about the Source Erosion. Seeing Xu Jing's troubled expression, he comforted her:
"Didn't you say that the best material is S3?
Don't worry, no matter how many S3 we catch, we won't give any to the doctor. We'll give them all to you. Are you satisfied?
With S3, you can make as many as you want … "
At this time, Xu Jing nodded. She planned to give up the Source Erosion in her hand in exchange for a promise from Zhang Xiaoqiang. With the addition of some of the Source Erosion, there were still thousands of zombie corpses behind the wall. Using the zombies to extract some of the impure Source Erosion would be enough for her to do other experiments.
After solving the problem of the Source Erosion, Zhang Xiaoqiang looked for Wang Le.
"Wang Le, today, your Catapult and Molotov Cocktail did a great job. They bought us an entire night's time. I will give the order to prioritize your material needs.
However, there is still not enough time. Can you make more Molotov Cocktail overnight? I hope they can be used until everyone is evacuated … "
This time, it was Wang Le's turn to look troubled. With a hoarse voice, he said to Zhang Xiaoqiang:
"Zhang Xiaoqiang, the gasoline is completely used up. The rest is reserved for vehicles that can't move. If we really need to use it, we can only destroy the trap in the central area. There are Molotov Cocktail made today."
The central area that Wang Le mentioned was Zhang Xiaoqiang's final trump card. It was the guarantee that he could retreat to the lake with his troops. Although Zhang Xiaoqiang led his soldiers to fight to the death, it would not cause too much damage to his troops. These soldiers had fought many battles, and their basic quality was much better than the troops left behind at the base. These soldiers were the capital that Zhang Xiaoqiang could rely on. Therefore, when it came to a critical moment, Zhang Xiaoqiang was willing to give up the entire colony to bring these troops with him.
After hearing Wang Le's words, Zhang Xiaoqiang hesitated for a while before instructing Wang Le:
"Try to collect the old tires and flammable things in the colony and throw them over the wall with the Catapult. Do your best and leave the rest to fate. Don't touch the trap."
Just as Wang Le nodded and was about to get busy, Huang Quan returned with a few subordinates. He walked over with a burly man at gunpoint. When he got close, the light illuminated the man's face. It was Wang Bing, whom Zhang Xiaoqiang had issued a wanted order for.
