Bragging always comes at a price. In order to store fish, Li Mu started the "canning experiment". Unfortunately, there are all kinds of drawings in the system, but there are no cans, because in the game, the inventory is "preserved" and everything can be placed in the inventory, so there is no need to make it into canned food.

At first, Li Mu was very optimistic because in his consciousness, it was not difficult to canned food. Isn’t it just to put the food in, seal it up and prevent it from rotting? However, when he really started to do it, Li Mu found that things were not as simple as he thought.

Because of the lack of necessary sterilization links, his cans will always rot. The best record can only last for three or four days, and the shelf life of these three or four days is far from meeting his requirements.

Moreover, the taste of the food in the canned food will also have an impact. Even during the shelf life, the canned food poured out is very unpalatable and makes it difficult to swallow.

After several experiments, they all ended in failure. Li Mu had no choice. He couldn't waste all his time on this matter. He still had a lot of things to be busy with. He couldn't do it himself, and he had a way. If he didn't have time, wouldn't we have money?

Li Mu ordered someone to post a notice, offering a reward of 1,000 taels of gold to solve this problem. If anyone can find an effective solution, 1,000 taels of gold will be given. If multiple people cooperate to solve the problem, then the 1,000 taels of gold will be equally divided. If someone uses the same method to solve this problem, then it will be first come first served, which is very fair.

When the news came out, Yangzhou Port was in full swing again. Countless people were almost flattening the threshold of Yuelai Inn. Everyone had some local methods to go to sea. Sometimes, going to sea only takes a month, and it would not be possible to supplement vitamins. The people of the Tang Dynasty did not understand what vitamins were not vitamins. They only had a simple idea to store as much food as possible. Although everyone had different methods, the effects were basically not much different.

One of the most common methods is to first put the food into a casserole, then steam it with a plug, and then seal it with wax. The "canned food" made in this way will be stored on the sea for a month.

But the taste is still unavailable, at least Li Mu cannot eat it. But for sailors, it is not a problem, because they are used to it, and some of them are good to eat at sea.

Li Mu had also learned about this method before, and it did not meet his requirements. Of course, all those who proposed this method did not get the reward. After learning that the money was not available casually, fewer people came, but the attention did not decrease. Everyone wanted to know what the Marquis' standard was, and how delicious canned food was to get the bounty.

Famous chef in Yangzhou, Liu Sanshao.

After he successfully handled whale meat, Liu Sanshao became famous. He was also left at Yuelai Inn by Li Mu and became his specialty chef. Li Mu gave the prize, and he knew it and tried it as soon as possible.

At first, he used steaming and cooking methods like the method on the market, but the disadvantages of this method, even if he is a famous chef in Yangzhou, cannot be solved. Food stored for more than seven or eight days is very unpalatable. He is a chef with picky taste buds and he has to have a long nausea every time he tries.

But he was not discouraged. As a famous chef who could remove the fishy smell of whale meat, he believed that he would handle it well and that his efforts would be fulfilled. Finally, he found the key to the problem.

During the test, Liu Sanshao found that no matter how the casserole was treated, it would not reach the level of non-rot, and if a porcelain bottle was used, it would be much better. Liu Sanshao vaguely felt that this might have something to do with the texture of the vessel. The porcelain is airtight and should be better than the casserole.

Then, in an occasional attempt, he cooked the vessel first because of a mistake. This time the corruption time was greatly delayed, and the taste of the food could be preserved for a longer time. Liu Sanshao guessed that perhaps it was not only the food that needed to be boiled, but this vessel was also a major reason for the corruption.

After finding these two major reasons, Liu Sanshao's R&D work stagnated because he couldn't continue, because even if the reason he found was the right one, porcelain was expensive and it was not realistic to use it in cans.

After struggling for a few days, Liu Sanshao finally decided to tell Li Mu about his discovery. Maybe the Marquis might have a solution. So, Liu Sanshao took advantage of the time when he delivered vegetables to Li Mu for lunch and found the right opportunity to tell his discovery.

Li Mu had an impression of Liu Sanshao. The cook was not old, but was the first person to find a solution to the fishy smell of whale meat. In order to reward him, Li Mu specially spent money to buy his patent and kept him to cook. After contacting him, Li Mu increasingly felt that Liu Sanshao was a talent. He had the rare spirit of research in this era. He did not stick to the rules in cooking and could always come up with some new tricks.

This time, Liu Sanshao's discovery made Li Mu look at him even more. Liu Sanshao has basically found the root of the problem. The two most important points of canning are sealing and sterilization.

Actually, Li Mu didn't know that he just didn't remember it for a while. After Liu Sanshao reminded him, he remembered everything.

The problem now is how to solve this problem.

First of all, the problem of can material. There is no doubt that iron, tin, and other metals are the most suitable for cans. However, it is impossible to do it at present. With limited mining volume and time to supply weapons and armor, how can there be a surplus for cans? This idea only went around Li Mu's head and was abandoned by him.

Then, I can only find a way to find a way on the clay pot. Li Mu could understand why Liu Sanshao said that porcelain bottles are better than casseroles because of their sealing properties. The porcelain bottles have glaze on them, which is the biggest difference. If you can also wrap a layer of glaze outside the clay pot, can the problem be solved?

When he thought about it, Li Mu found a potter and asked them to try it. The effect was as feasible as Li Mu thought, and the cost was not high.

The first problem is solved, and there is only one problem of sterilization left.

The method of steaming porcelain bottles that Liu Sanshao mentioned is actually external sterilization, which can play a certain role, but it cannot play a fundamental role. If you want the things in the canned food to not rot, the most important thing is how to sterilize the food.

Just thinking alone can't find a solution. Li Mu came to the kitchen for the first time and conducted an experiment with Liu Sanshao. After countless rounds of failure, he finally found a solution for them.

This method is relatively complicated. It is not enough to rely on them alone, but you have to get a potter.

The specific implementation steps are as follows: First, make a wide-mouthed can, steam and sterilize it, and reach the level of sterility inside and outside. Then put the prepared dishes, sauce meat and fruits into the jar and add appropriate amount of boiling water.

Next, add a lid of the right size on the clay pot. This lid must also be steamed and disinfected to ensure sterility. Use a screw port, that is, screwed on, so as to achieve maximum tightness and save wax when sealing with wax.

After doing this, you must put the canned food on the fire and roast it.

The lid has a small hole. When heating the tank, the water inside the food will evaporate. The evaporated water vapor can only be discharged through the small holes. In a narrow space, the high-temperature water vapor will change the pressure and reach a high temperature and high pressure state, and most of the bacteria will be killed. Then, the small hole is sealed with wax, and the bacteria outside cannot enter, so that the maximum sterility can be achieved, and the nutrition of the dishes will not be lost.

"It's done!"

More than ten days later!

Li Mu tasted the dishes in the canned food, patted Liu Sanshao on the shoulder, and said, "Congratulations, I can apply for another patent. With this thing, I don't have to worry about the rest of my life, and I will definitely spend endless money."

After almost a month, after dinner every day, he spent experimenting with Li Mu. Liu Sanshao's knowledge was not comparable to that of the past. He understood many things from Li Mu, such as how patents turned into money, etc. He knew that what Li Mu said was not false. If he applied for a patent for canned food, in the next twenty years, every canned food in the Tang Dynasty would theoretically give him some patent fees. Without further ado, it would be hard to imagine how much money it would be.

But he doesn't want this money, and he can't ask for it either!

Only Liu Sanshao knew in his heart how much he had contributed to the secret method of this can.

Did he solve the problem? He didn't solve anything. In about a month, he only did one thing, which was to cook repeatedly. What should we do, how to solve the problem, and how to come up with ideas were all thought out by the Marquis himself. He just did what a chef should do, that's all.

But the Marquis never mentioned what he did. Now that the canned food research has been successful, he also put all the credit on himself.

This, no!

How can Liu Sanshao, a famous chef in Yangzhou, be a shameless person?

Although that may be a money that can never be spent in a lifetime, what is the use of money if you lose your duty and money?

What's more, I am a famous chef in Yangzhou and have the skills to do so, so I will never be hungry in this life. No matter how much money I have, what can I do?

After understanding this section, Liu Sanshao mustered up the courage and said, "Marty, I can't take this patent. I didn't do anything, I feel ashamed of it."

"Oh?" Li Mu swallowed the food in his mouth, looked at Liu Sanshao, and said, "You have to think about it. This is not a small amount. A rough estimate of twenty years is that it is hundreds of thousands of yuan. Are you sure you are not moved?"

When Liu Sanshao heard the number of hundreds of thousands of guan, his eyes shook. He was also a human being. How could he not be moved when facing such a large number? But after a change of thought, he figured it out that he would not be at ease even if he wanted it. Moreover, he had determined to be a good chef in his life. Yangzhou famous chefs are not enough, so he had to be a famous chef in the Tang Dynasty. These are accomplished by constantly improving his skills, and they are definitely not done by how much money they make.

"The Marquis' kindness, the villain has received it, but the canned patent was completed by the Marquis. The villain did not do anything and dared not take credit for this patent. The villain cannot ask for this patent."

Li Mu smiled and said, "I won't argue with you, don't want to be idle..." Seeing that Liu Sanshao still shook his head, Li Mu said, "Are you sure you don't want it?"

"don't want!"

"Then I don't want it either." Li Mu spread his hands and said, "You don't want it, I don't want it either. No one wants it anymore?"

"Justice Marquis will do it. It has nothing to do with the villain anyway." Liu Sanshao was also a stubborn person. He packed up his things and saluted Li Mu, saying, "Justice Marquis is slow to use, the villain needs to prepare the ingredients for dinner."

As he said that, he was about to leave. Li Mu stopped him and said, "What are you going to do? You don't want it, either, I don't want it, but there must be a place to go, right? Since this matter is a cooperation between you and me, I have to discuss it with you. It's better to set up a charity association and donate the money to this charity association. If a sailor encounters an accident in the future, this money can help him maintain a family. It is up to to treat it as doing good deeds and accumulating virtue. What do you think?"

"The Marquis does good deeds and accumulates virtues, which is a good thing. This is the Marquis' own business. Just a villain only cares about cooking." Liu Sanshao looked clear and wanted to leave. Li Mu grabbed him and said, "I didn't expect that you are quite stubborn and don't even want money for you? Okay, you don't want the money for patents, you can always keep the money for business, right? Can you always keep the money for cooking?"

Liu Sanshao thought for a while and said, "The villain is a chef, so of course he can get the money for cooking."

"That's all!" Li Mu let go of him and said, "Look soon, the fleet will go out to sea. You know, it will take several months to go out to sea, and the supply must be kept up. It would be fine if there was no conditions before, but now you can make canned food, you must prepare it for your brothers. Tomorrow, I will allocate 50,000 guan to build a canning factory. You are responsible for grabbing this piece, not limited to canned meat, canned vegetables is the top priority, and all kinds of fruits can be arranged. Aren't you cooking? All of these are left to you. In short, there must be many types and delicious, the faster the better. If you don't have enough people, you don't have enough money, you don't have enough money, you don't speak enough materials, just speak, I just want fast, speed, efficiency, understand?"

"As long as it is cooking, villains can do it!" Liu Sanshao patted his chest and promised that cooking was learned from other things. He could make one can of a flavor and make a second taste. Thinking that people went to sea in the future and ate the cans he made, Liu Sanshao suddenly felt that his chance to become famous. From now on, as long as he was a sailor going to sea, there would be no one who did not know him Liu Sanshao.

"Mr. Marquis, the villain will definitely live up to his entrustion!"

Li Mu finished his last bite of canned beef and said, "It's up to you, too, don't tell anyone about canned beef. If someone asks, what do you know?"

"I understand, the cow fell to death."

"Stupid!" Li Mu corrected: "There is no such thing as beef at all. My husband eats whale meat. Can you get rid of the fishy fish? You can't tell me this?"

"Ah..." Liu Sanshao suddenly realized, and said, "The villain is not good at using his brain. Remember to mess around. The Marquis has never eaten beef, it is all whale meat."

“It’s almost the same.”
