End of World's Businessman

The vaccine formula provided by Jingcheng also used the extracts of mutated plants. In addition, they also used special parts of several mutated animals and mutated bugs. Although the effect of the formula was not as good as that of Lancheng, it brought Li Yuan and the others A great inspiration.After further improving the formula, the vaccine produced by Lancheng now has a cure rate of 45% for ordinary people and 60% for people with supernatural powers. The cure rate is already quite high.

With the further development of research and a large number of clinical trials, Li Yuan and other researchers found that the cure rate of the vaccine continued to decline with the increase of the level of zombies. Every time the level of zombies increased, the cure rate of the vaccine would drop by 5% or even More, according to their data model prediction, the effect of their upgraded vaccine is close to zero when dealing with wounds caused by level 6 zombies.At the same time, the fusion-infected zombie virus is highly resistant to the vaccine. Even if it is only bitten by a first-level fusion zombie, the vaccine is only half effective in curing it. approaching zero.

However, the perfect vaccine provided by Wu Ye still has a 100% healing effect, and there is a certain chance of awakening the ability.However, it is a pity that they have not been able to research two or three of the main ingredients, and the substitutes they have found have always been unsatisfactory.

After the Li family was forced to announce the vaccine formula, the Corpse Hunter Union in Lancheng set up a long-term task of purchasing mutated plants, animals, and mutated bugs on the formula. Because the task rewards were very generous, many people were willing to take risks and go to the mountains near Lancheng. Look for mission targets on the periphery.Lancheng's geographical location is relatively good, and the surrounding area is very suitable for plant growth, and most of the raw materials for medicines are quickly gathered.

If you really can’t find the part, let the caravan help you find it, and communicate with each other’s settlements.

More than a month later, Lancheng's upgraded version of the D virus vaccine was successfully launched, and each vaccine was clearly priced at 3500 crystals.If the injured person who is a permanent resident dies during the treatment, he can pay nothing; citizens of the second level and above are allowed to buy on credit; many.

It is difficult for the survivors of Lancheng to question the citizen hierarchy proposed by Wu Ye. After all, the real benefits are all visible.

Wu Ye unified the price of 3500 crystals/bottle to Lancheng, and then sold it to the survivors in Lancheng.After all, Wu Ye is not doing charity. He has invested a lot of cost in the research institute and the raw materials produced by the samples and systems, and his hands are always tight.The credit system will inevitably accumulate a lot of funds, and the later collection will have to go through Lancheng's financial system. He simply trades directly with Lancheng, and then Lancheng will trade with the survivors, a win-win situation for all parties. The 1500 crystals/bottle of the vaccine, after excluding the cost and expenses, and the rewards and dividends to Li Yuan and others, can only earn 1500 crystals in his hands at most.

On the other side of Lancheng, there is capital to manage it there, and the city lord promised that the deceased would not have to pay any fees, and the profit margin was very small.Therefore, Lancheng can only find ways to reduce the risk of death.

According to Li Yuan's research, after being injured by a zombie, the sooner the vaccine is injected, the higher the recovery rate will be.Corpse hunters with spare money will buy one or two vaccines on their bodies for emergencies. However, credit purchases are not allowed for vaccines purchased in advance, but there is a special device on the vaccine syringe that can monitor whether the injector is dead. Immediate family members can apply for a refund based on the DNA of the deceased and the information on the syringe.

Lancheng did not announce the cure rate of the upgraded vaccine. In fact, after the Li family’s vaccine formula was forced to be released, many scientific researchers in large and medium-sized settlements used the formula they provided as the mother, and more or less compared the formula. Improvements have been made, and the cure rate has been improved compared with the original formula.

The prices of vaccines in different settlements are also different, and the price of vaccines in Lancheng is considered to be very expensive among them, but the dead do not need to pay any fees, which largely dispels everyone's dissatisfaction.In the eyes of ordinary people, the cure rate of the vaccine is only [-] to [-]%. After careful calculation, they are actually making a profit.

Such a price is unfair to survivors?It's good enough to recover a life from the mouth of a zombie, what else do you want?

For the first batch of upgraded vaccines, Wu Ye directly traded 1W finished products to Lancheng, earning 300W transparent crystals in one go, and the income is very considerable.After Lancheng put the vaccine in the hospital, it sold more than 2000 pieces in just one week.Among them, most people buy them there just in case.It has to be said that Qingmin County's pioneering action made some corpse hunters in Lancheng rich first, and accumulated some surplus money in their hands.

Wu Ye has worked hard for a year, and finally he has his own "industrial enterprise" in this plane, which can bring him long-term and rich benefits.After the vaccine factory was completed, the corners of Er Shao's mouth were raised high for several days, and the invisible little tail behind his buttocks almost turned up into the sky.

The good mood didn't last long, and a new situation appeared.

Some mutated insects also grew energy crystals. The crystals were similar to the transparent crystals in both color and size, but the energy contained in them was only half of that of the transparent crystals, and some of them were even less than that.The energy of these crystal nuclei can also be used by supernatural beings, but the difference in energy content is so large that no one wants this kind of crystal nuclei.

After Wu Ye received the information, he went to the research institute with Qin Wuhua to find Professor Li. After exchanging pleasantries, he explained the general situation and asked, "Uncle Li, can you help me make a test that can identify the energy content of crystal nuclei?" tools come out?"

After looking at the mutated insect crystal for a while, Professor Li said, "I'll try it first, and I'll give you an answer as soon as possible." The performance of the upgraded version of the brain is very good, and it can help Professor Li model and analyze, saving a lot of trouble. It's not that the data in the database is not enough, it can do more things.

Wu Ye nodded: "Okay, then you are busy first, and Daqin and I will go to the plantation."

This year's weather is very dry, and the situation in Lancheng is not bad. The groundwater resources are abundant. Not only have no crops died of drought, but because the sunshine is higher than the previous temperature, the growth of plants is very good, and more crops have mutated.

After Wu Ye and Qin Wuhua walked around the plantation for half a circle, they walked to the tree of life that made Wu Ye's heart ache, and Ji Chong happened to be there.He just finished casting the power on the tree of life, and the tree of life looks very good, with many small flower buds, but before it reaches adulthood, these flower buds will not bear fruit.

After a brief exchange of pleasantries, Ji Chong told Wu Ye: "...I found that the probability of crop mutation near this tree is much higher than that in other places. Young Master Wu, can you tell me what is going on with this tree? ah?"

In addition to the fruit that can be made into various medicines, the tree of life itself contains pure and powerful vitality, which can promote the growth and mutation of plants.It was for this reason that Wu Ye had the heart to exchange two packs of high-energy fertilizer for it.At present, the research institute is actively researching the high-energy fertilizer he provided. They have never seen many ingredients before, and the progress is not much.

"If it's useful, you can give it more powers every day, and keep it close, so that no one can hurt it or steal it." There are thousands of survivors coming and going in and out of the plantation every day. In the season, more people come in and out, and safety issues must be taken seriously.

Ji Chong didn't hear the answer he had been curious about for a long time, so he curled his lips and said, "That's up to you."

Just as he was talking, the sky suddenly darkened. The place where the sun fell in the sky was covered by darkness, and an invisible black cloud was moving rapidly towards the direction of Lancheng.

The system finally released the first mandatory task in this period of time: [Mutated insects are attacking, guard Lancheng. 】Wu Ye's face darkened, and he focused on two tasks while communicating with the system, and at the same time called Ji Xiang, asking him to let people fully open the energy shield immediately.

Two minutes later, a layer of translucent energy shield wrapped Lancheng.

Outside the city, a few corpse hunters who had just returned from the hunting area saw the densely packed insects in the sky, and could hear the humming of their wings in their ears. Everyone's expressions changed drastically in fright, and they rushed back to Lan as quickly as possible. city.

At this time, it was already 07:30 in the evening. Since it was getting dark late, the corpse hunters would extend their working hours in order to hunt more zombies. At 08:30, there were as many as ten thousand corpse hunters outside the city at this time.These people rushed to the city gate desperately, the detection at the gate was too late, and many conflicts had already occurred at the gate, if this continued, the corpse hunters might force their way in.There is nothing wrong with letting these corpse hunters in, but I am afraid that some of these people will be infected with zombie virus or be parasitized. Once these people are let in, the consequences will be disastrous.

When Wu Ye received Ji Xiang's anxious report, he frowned so much that he could kill a fly.Qin Wuhua heard it clearly from the side. He frowned and said, "Aye, this is not going to work. Whether it is a conflict breaking out or locking these people out of the city, it will not be conducive to the next action." Breaking out of conflicts will cause chaos Not to mention that keeping those people outside the city will also cause chaos. These people will definitely not wait to die obediently, and will definitely attack the energy shield, causing unnecessary losses.

Wu Ye directly asked the system: [How long will it take for those bugs to reach Lancheng at the earliest? 】After the cosmic mercenary system is upgraded to a certain level, it will open the function of assisting combat. System monitoring is one of them, and system warning is another function.Wu Ye's exchange quota has already reached the level where the early warning function can be activated, but like monitoring, early warning also needs to consume points and energy. A single early warning requires 1000 points and 6 red crystals.

After the system made a quotation and agreed to deduct the points and red crystals of the stupid host, the cold mechanical voice began to report the situation of the mutated insect swarm: [Tens of millions of low-level insect swarms are still 40 kilometers away from Lancheng, and it is expected to arrive in 30 minutes. In Lancheng, the swarm of insects is very likely to detonate the swarm of corpses. Please prepare for the battle. 】
