"That green solution is purified by dissolving hundreds of evolutionary zombies, I named it the eclipse source, the raw material is the gastric juice of the giant big black fish, the gastric juice will mutate after dissolving the zombies, the initial suspicion is that the virus reacts with the gastric juice, the more viruses, the greater the reaction, theoretically speaking, that thing can cause absolute damage to the D2 type zombies, but the skin and bones of D3 can effectively resist this impure erosion source.

I tried and tested, but I couldn't purify it again, even if I used Type 2 zombies as raw materials, and then we got an S3 type zombie ......"

Zhang Xiaoqiang Jing listened to Xu Jing's narration, and when he heard what Xu Jing said, he was a little puzzled, the only S3 was treasured by the doctor, and it was said that the research value was greater than that of the D3 zombie, how could it be obtained by Xu Jing?

"S3, you say? Is the doctor willing to give S3's body to you? ”

Zhang Xiaoqiang couldn't understand what the doctor was doing, and the doctor was assured by S3 that there would be breakthrough results, could it be that the doctor's research was successful? But why didn't it report to him?

"Does the doctor have an S3 too? What I got was alive, huh? ”

Xu Jing was confused when asked, the doctor had an S3 zombie corpse, she really didn't know, and she had the heart to go to the doctor again to snatch the corpse back for research.

"Wait...... I'm confused by you.,You said that the S3 you got was alive.,But as far as I know.,S3 only appeared once.,It's the mysterious zombie that made the whole gathering place uneasy.,Where did you get it? ”

Zhang Xiaoqiang had to figure this matter out with Xu Jing, to know what a live S3 means? Last time, Zhang Xiaoqiang personally took action, and there were four evolutionaries who fought together, and the five evolutionaries could only force the S3 zombies to retreat, and there were dead people, and finally relied on the police ambush to kill the S3, for no reason, Xu Jing got a live one, and he couldn't believe it anyway.

"What I gave me was alive, my limbs were cut off, and it was sent from the other side of the river, as if the soldiers who sent the zombies said that it was caught by the snake......"

As soon as Xu Jing said this, Zhang Xiaoqiang understood, it was the blue-colored zombie, it was said that the zombie couldn't even stop the puppy and Yang Keer, or the mutant snake bit it, otherwise it was not just three people who died under its claws, thirty people were possible, Zhang Xiaoqiang didn't take it seriously at the time, thinking it was S2.

"Are you sure? It's really an S3 zombie, it can't be close to S3, right? ”

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

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

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

Zhang Xiaoqiang interrupted Xu Jing, horrified in his heart, the zombie that sneaked into the gathering place last time was not S3, but S4? When it comes to S4, the zombie's skin turns white, knows how to disguise, and the speed can surpass his dynamic vision in a short time, and the speed of the S3 type zombie should only be twice as fast as S2, about the same as Mu Peipei, you know, the S2 type zombie is not enough to touch Zhang Xiaoqiang's dynamic vision, obviously, the doctor won the jackpot, the legendary S4, it is also the first Type 4 zombie killed by Zhang Xiaoqiang, of course, this is not good news, the S4 type zombie is out, will the D4 type zombie be far away?

"By dissolving the virus in the S3 type zombies, we obtained a pure solution of the eclipse source, which is more than ten times more powerful than the gastric juice of large fish, and more refined than the gastric juice of large fish.

It has been tested to melt the bones and skin of D3, and in addition, it can also dissolve most organic matter, slowing down the dissolution and erosion of the soil, but the purity requirements are very high, and once other magazines are added, it will be reduced to gastric juice.

In addition, the erosion source is also lost, a certain percentage will be lost when dissolving D3, on the hardest bones and outer armor of the zombie, the loss is obvious, just now I used the only erosion source to corrode D3, and the proportion of recovery is only 40% more, according to the volume of the zombie, it should be more than 120% to 150%.

Therefore, if you want to manufacture it on a large scale, you must use a large amount of S3, and for each dissolved S3, the amount of erosion source that can be obtained can be increased by at least 60%. ”

Xu Jing's words made Zhang Xiaoqiang have the most intuitive understanding of the so-called erosion source, this is a treasure, but the limit is also high, you must use type 3 zombies as fuel in order to get more erosion sources, but in use, there will be loss when encountering hard objects, you must be careful when using it, and you can't add impurities.

Zhang Xiaoqiang and Xu Jing's Q&A was listened to by Wen Wen, Wen Wen wanted to scratch like a cat's paw in his heart, he was eager to get an eclipse source, as a weapon to deal with type 3 zombies in the future, this afternoon's battle made him lose confidence in high-level zombies, and he couldn't even break the skin, how to develop his chosen one in the future, you know, their goal is to become the pinnacle of the world, not to be a mouse.

"Then what eclipse source in your hand can you make two copies, tomorrow it may be on the ground, plus red arrow eight, if you are lucky, you can't clean up the remaining d3 together."

Zhang Xiaoqiang paid attention to the source of erosion, and saw that Xu Jing's face was difficult, so he comforted:

"Didn't you say that the best material is S3? Don't worry, no matter how many s3s you catch, you won't give any of them to the doctor, all of them will be given to you, satisfied, right? With S3, you're not doing as much as you want......"

At this time, Xu Jingcai nodded, thinking in her heart, giving up the eclipse source in her hand, in exchange for a promise from Zhang Xiaoqiang, plus she deducted a little from it, there were thousands of zombie corpses behind the wall, and using zombies to extract a part of the impure eclipse source was enough for her to do other experiments.

After solving the matter of the eclipse source, Zhang Xiaoqiang found Wang Le's head again.

"Wang Le, your trebuchet and Molotov cocktail have made a great contribution today, buying us time all night, and I will order you to go down and give priority to your raw material needs.

However, there is still not enough time to make more Molotov cocktails overnight, and I hope to use it until we all evacuate......"

This time, Wang Le's face was embarrassed, and he said to Zhang Xiaoqiang in a hoarse voice:

"Brother Cockroach, the gasoline has been completely used up, and all that remains is the immovable vehicle reserve oil, if you really want to use it, you can only destroy the trap in the central area, where there are incendiary bombs that are being made today."

Wang Le said that the central area is Zhang Xiaoqiang's last hole card, is the guarantee that he can lead his troops to retreat to the lake, although Zhang Xiaoqiang with his soldiers will not retreat, but will not let his troops have too much attrition, these soldiers have fought again and again, the basic quality is much stronger than the base of the remaining troops, these soldiers are Zhang Xiaoqiang's capital to settle down, so, once it comes to the critical moment that it is impossible to violate, Zhang Xiaoqiang is willing to give up the entire gathering place, but also to take these troops away.

When Wang Le said this, Zhang Xiaoqiang hesitated for a long time and explained to Wang Le:

"Do your best to collect the waste tires and everything that can be burned in the gathering place, throw them over the wall with trebuchets, do your best, obey the fate of God, and don't move the trap."

Just when Wang Le nodded and was about to go to work, Huang Quan came back, walked over with a few subordinates, pointed a gun at a burly man, and approached, the light illuminated the man's face, but it was Wang Bing, who was wanted by Zhang Xiaoqiang.
