"The black is the immune agent, the white is the buffer drug, it will be more comfortable to use, if you don't use it, the user's body will maintain a slight burning sensation for up to eight hours, this feeling will not be fatal, it will only bring slight damage to your body, of course, if the person with enough recovery can ignore it, if not, you will have to inject the buffer agent afterwards. ”

Zheng Yichen quickly explained.

"Injection?"

The person in charge keenly heard the special place in Zheng Yichen's words.

"Well, injection, this medicine can only work quickly through the blood, because injection is the best way, and it can effectively reduce costs, after all, with the way of drinking, it takes twice the dose to exert enough effect. ”

"Okay, I see, the church will be put into use in a certain range after testing...... By the way, what did you inject it with?" the person in charge nodded, and put away the two vials of sample elixir, with the recipe for this black and white immunity elixir next to it.

"Well, do you want to buy and order? After you have syringes, you can reuse them as long as they are cleaned, and you can buy a lot of needles, which are disposable consumables, and those things are not easy to clean. Zheng Yichen took out a few syringes of different specifications, cleaning up or something is not casually talked, there is no sterilization cabinet in the other world, and the disinfection cabinet is not necessarily good for this kind of thing.

But they have magic, and through magic, they can be sterilized aseptically.

"......" looked at the syringe that Zheng Yichen had prepared, the person in charge couldn't help but look at him more, and resisted the urge to say You are really a profiteer, this kind of thing is cheap at first glance, and it is something that needs to be produced in large quantities, speaking of which Zheng Yichen seems to be very good at producing these fine things in large quantities, and other alchemists can also do it, but after all, it is a waste of time, and it is impossible to put all your energy into such production.

Even if it takes ten seconds to produce one, sixty is ten minutes! A day is almost over for thousands of dollars, and what about the cost of such a thing? A few copper coins are cheaper, which means that the price of a few thousand syringes is only about one gold coin...... The price couldn't be lower, so how could those alchemists be idle and toss this kind of thing?

Spend a whole day making something better, and it's not just this price, their time is really gold.

So I don't know how Zheng Yichen is a large number of rapid production of this kind of thing, the relevant market competition is very low, basically no one fights with Zheng Yichen, which also creates that Zheng Yichen's online store has a lot of small profits and quick sales of goods has always been in a state of monopoly, and the inventory of those goods is unlimited, which also leads to some businessmen can't help but 'buy' on Zheng Yichen's side.

Again, when others think that the money of a copper coin is not money, the merchant attaches great importance to the interests of this copper coin.

Zheng Yichen is even more advantageous in the development of many aspects, the same is true of this kind of needle now, isn't it just thrown away after using the low price? As for using magic disinfection to restore to the original sterile state, I think too much, it is better to buy two new ones with magic skills!

In addition to this kind of thing, there is also a plastic bag thing, this kind of thing is also a hot sale commodity in Zheng Yichen's online store, after all, that thing can also be used when you take it out, although it is not like an expansion bag, but the applicability is very extensive, you can use it when you buy some bits and pieces, and you can also use it when you buy some breakfast.

The major shops are prepared, for businessmen they like this kind of thing too much, in the past, some people buy things, especially groceries, buy more stores will basically send a bag, but those bags are not cheap plastic bags, but cardboard bags or cloth bags, even if it is not a good material, but when it comes to the price, the price of a cardboard bag can also buy ten plastic bags, as for cloth bags, it is a dozen!

In this comparison, those shops like these plastic bag consumables made by Zheng Yichen too much, as for the problem of pollution...... Hawkers, anyway, there is no pollution here in the other world, after all, there is free elemental power in the air, and there is earth element in the ground, and after things are buried, they will be affected by the elemental power, and there will be two situations for dead things, either the retention time is far greater than that of the earth, or the speed of decay is faster than that of the earth.

Plastic bags are not made in strict accordance with the way on the earth, and they are also magically involved, although they are not considered magical products, but because of magic, they attract more free energy than conventional dead things, so the existence time of this thing is at least ten times shorter than that of plastic bags on the earth, and it will almost decay in about ten years.

However, plastic bags are this kind of thing, and the speed of replacement is very fast, so ten years should be a long time, anyway, after this cheap thing is sold in large quantities, there is no need to consider the problem of hoarding, and the out-of-stock shops are directly purchased in the online store in the Demon Soldier Summoning Book, and there is no need to store more at all, and even the village has stored more than ten years without using up the weight.

In addition, there are things like water pipes, the material of that thing is better than plastic bags, as long as it is not malicious damage, the time that can be used can be said to start for decades, whether it is a pipe or something else, all kinds of daily consumables or something, Zheng Yichen has tossed out a lot, and has been subtly changing the style of many details in the other world......

Well, the process of the invasion of the earth style does not need someone to vigorously promote anything, as long as there are many details on the change bit by bit, these details can start from the daily necessities or convenience, with a certain degree of convenience, in the slow improvement of this 'convenience', just like boiling a frog in warm water...... I don't need to give you any special stimulation at the beginning.

What kind of hell is this thing so powerful, how did you get it...... Zheng Yichen said that he has time, and it is not a problem to have a hundred-year plan, so the problem of incompatibility of the painting style can be changed bit by bit, and when more and more powerful things gradually appear, no one will think that the painting style is any different.

For example, I saw a little sister three years ago, and after three years, I will have a feeling that I have grown really fast and changed a lot, but if I contact it every day, I don't have such a feeling.

All in all, Zheng Yichen said that he drove very steadily, and he would definitely not overturn at some point because the speed was too fast, after all, there are many big forces in this world, and Zheng Yichen has not had much contact with the dark church, and he can't ignore it, the Templar church is more like the protagonist of the times.

It was not Zheng Yichen's original intention to stop me from dying, so naturally I had to stabilize and change the style of painting, the power of habit is strong, take the current earthlings as an example, suddenly the mobile phone was completely paralyzed, the computer was scrapped, and I don't know how many people will be uncomfortable and want to run away.

After that, the water and electricity are cut off, and if you want water, you need to carry it yourself, and if you want electricity, you need to pedal the generator to generate electricity...... Who wants to experience that life without being fine?

Take the current situation as an example, whether it is the water pipes and faucets that can be connected by cheap civilians, or the convenient plastic bags that are used, if there are no more, those who are used to these things will feel very inconvenient, in addition to these, there are too many other sundries in Zheng Yichen's online store, those folding chairs, school bags, shoulder bags and the like...... Well, it won't make people feel abrupt.

After all, those things are all there, but the style and design will not seem very convenient, Zheng Yichen makes it biased towards the terrestrial style to greatly increase its practicality, but this kind of thing is easy to imitate, such as schoolbags, shoulder bags, travel bags, such things, excellent tailors can make it, folding chairs, carpenters can easily do it, some Zheng Yichen still doesn't want to admit that others do better than their own!

Tut!

As long as the road is paved and the power of inertia is there, even if he does not become a guide in the future, according to the power of inertia, the style pattern is already there, and there will not be much deviation in the subsequent development.

Therefore, Zheng Yichen is improving the 'puzzle' bit by bit from the basics, and when doing certain things, as long as there is an opportunity, he will let a 'novel' thing appear in the eyes of people in the other world, these things are taken out with the needs of the time, giving people the biggest feeling that in addition to novelty and convenience, Zheng Yichen's creativity is high enough, and he can always create the convenience products he needs when he needs something.

The syringe was taken out at the right time, and it started from the Templar Church, which was equivalent to getting a legal certificate...... And according to Zheng Yichen's previous experience, I believe that after this thing is circulated, the people of the other world will develop new usages.

For example, something like an infusion set, after all, the plastic is already there, and Zheng Yichen has already guided out the basic plates, so that others can give full play to their IQ and take these basic plates to spell out new pictures.

"This thing...... Okay, it looks pretty good, I'll report back. The person in charge of the quarantine camp took a look at the syringes and put them away, muttering to himself, how can the more I look at this thing, the more I think those researchers in the field of life will like it?

They also have similar things, but they are not as simple and convenient as Zheng Yichen came up, and the cost is not low...... This thing,I'm afraid it will not be sought after by those deputies in the future.,After all, this thing looks not only simple and convenient.,There's a scale on it.,Not to mention the degree of accuracy.,It's better than nothing.。
