This sentence is really lovely, for Yang Qingfeng's things made by zuò, even if there is a problem, Zhang Yuntian can't find it.

Zhang Yuntian took these materials back to the dormitory and studied them carefully, the vaccines and antibodies naturally needless to say, after improvement, they can be perfectly adapted to the human body, the key is the information of the disintegrator.

How long does it take to decompose the brains of zombies, this is the most important thing, if even Yang Qingfeng can't shorten the working hours of the decomposers, then the people who can do it in the entire federation can basically say that they will not be able to survive anymore.

Zhang Yuntian opened the disintegrator's profile, which also included a demonstration of the results of the simulation system.

Since zombies belong to corpses, the circulatory system and respiratory system in their bodies have all stopped functioning, and the disintegrators cannot reach the zombies' brains through these channels, and the decomposers are so small that they can't "crawl" to the brains from other parts of the zombies, and even if they can, the speed must be so slow that even a microscope can hardly observe.

Therefore, it is best to spray down from a high place to release the disintegrator directly to the zombie's head, and then it only takes a maximum of an hour to dissolve the zombie's brain into thick juice.

And that's not all, the disintegrators are fungi, they will grow like mushrooms from the holes in the eyes and mouths of zombies, and after five hours of maturity, their spores will continue to infect other zombies until all zombies are disintegrated!

Zhang Yuntian looked at the screen dumbfounded, this kind of thing is too domineering, it is simply a plague among zombies, if they are thrown into tens of millions of corpses, and then find a way to hinder their progress, then in a few hours, the sea of corpses will become a sea of mushrooms, I just don't know if this mushroom can be eaten, if it can be eaten, even the problem of food will be solved.

He thought about it for a while, at this time the sun was just setting in the west, Chen Lu, this kid didn't know where to run again, Zhang Yuntian was bored, thinking of the contribution of more than one million yuan he had, he decided to try his luck in the second-hand market, after all, such a thing as spraying disintegrators must not be operated with a watering can.

After the start of the school year, the second-hand market is obviously more popular than ever, not only the main thoroughfares, but also some side roads have been utilized, the streets are bustling with people, most of them come to have a look, by the way to buy some strange antiques to go back, another group of people come here like a shop pù to sell their small inventions, hoping that they can have a place on the counter to subsidize expenses.

Zhang Yuntian wandered around the street with great interest, most of the shops on the street sold some medical instruments and equipment, such as weapons and armor, and they did not dare to sell them openly, as for some contraband, he also visited several large and small shops, all of which were very careful, and the last time he was able to find an artifact like the Mother Cultivator, it was completely due to luck.

Suddenly, he was attracted by the noisy sound in front of a shop across the street, a boy of the same age as Zhang Yuntian, who was holding a canister-shaped object in his arms and carrying a huge backpack about the size of his body.

The student looked at the invention in his hand dejectedly, regained his spirits, and came to a shop next to him, before he could speak, the boss in the shop pù directly shouted with a straight face: "Go, go, we don't buy any inventions, take advantage of my good mood now, hurry up, don't block the door, delay my business!" ”

The student still did not give up, put the invention on the counter, and began to introduce it in detail, he spoke in a small voice, but the boss's voice was very loud, and it sounded like the boss was whining in person.

The owners of these second-hand stores are all human spirits, and what kind of things have a market and what kind of things can't be sold can be seen at a glance, so if the bosses reject them, even if they are placed in the store, it is difficult to sell them, but they occupy a seat for nothing, affecting income.

Zhang Yuntian couldn't help but sigh, thinking of the dilemma that he couldn't even contribute to the game before, he felt a little more sympathy for this boy.

"What do you want to see?"

An old man with a smile asked at Zhang Yuntian, who noticed that he had accidentally blocked in front of other people's shops and was about to apologize, when he suddenly found that the layout of this shop was very antique, but it had both the decoration of the classical gold tiles and red walls of the Huaxia Kingdom and the Western-style Roman-style buildings, which felt a little nondescript.

Zhang Yuntian walked in and said casually: "Just take a look!" ”

Probably there are few customers in this shop, the boss followed behind Zhang Yuntian diligently, and kept recommending while walking, "Our store pù is the most distinctive on the whole street, about the information related to ancient buildings, the equipment is not available in other people's homes except for our home, if you want to find something in this area, you can be regarded as the right place!" ”

"Look at this building restoration equipment, it can convert any holographic architectural drawings into holographic images, so that people can immerse themselves in the unique charm of different buildings, if you buy it, I can also send you twenty sets of holographic drawings of ancient buildings, and you will be able to enjoy the leisurely and comfortable life of the ancients at home in the future..."

The old man kept chattering in Zhang Yuntian's ear like a mosquito, which made the latter feel that the desertion of this store was mostly related to the old man's nagging, if he hadn't adapted to being harassed by sales calls in the main world, I am afraid that he would have had a psychological breakdown at this time.

"Okay, okay, I see, can you let me watch quietly for a while?"

Zhang Yuntian impatiently interrupted the old man's words, the latter was stunned for a moment, and then said: "Okay, of course, but I strongly recommend that you take a look at this device..."

In fact, the product introduced by the old man just now really made Zhang Yuntian excited, but he was afraid that the old man's words would escalate, so he deliberately put on an indifferent attitude, ready to go around, and then buy it.

Suddenly, a huge storage box on the shelf attracted Zhang Yuntian's attention, "What's in here?" He was afraid that the old man would commit an occupational disease, so he added, "Long story short, thank you!" ”

"This is an architectural scanning device!" The old man was obedient, so he jumped a word, and he didn't even have an explanation.
