Is the eldest brother an official? These words are just like a talisman, when the backer in the mouth of the leopard master came to the scene, he originally wanted to play majestic, but when he looked at the young man, this guy was immediately scared stupid, my Sanqing Daozun Guanyin Bodhisattva, how did His Royal Highness the King of Han get to this place of three religions and nine streams?

After settling the case, Li Chengzong immediately apologized to the people, and after a wave of fame, Li Chengzong left here with Pei Fuer.

The two walked and walked to the loading and unloading area, Li Chengzong saw that the ships here were loading and unloading goods, these goods are boxes of canned food, yes, it is canned, speaking of which can also be related to Li Chengzong, in order to build this prosperous single city, Li Chengzong vigorously developed marine trade, but the sea is so big, the seafarers who have lived on the ship for a long time began to get sick because they could not eat fresh vegetables, fruits and other foods, and some also suffered from serious life-threatening scurvy, Even if the Chinese people come up with such a miracle as growing vegetables on a ship on the sea and sending bean sprouts, it is a drop in the bucket after all, and people urgently need a food storage technology that can keep it fresh for a long time.

Therefore, Li Chengzong and Yang Rong took out a huge bonus of 12,000 silver to solicit a way to store food for a long time.

It is said that there must be brave men under heavy awards, and many people have invested in research activities in order to win awards. Among them, Hu Peisong and his wife, who are originally from Mingzhou, Datang Dynasty, who deal in candied food, have used all their energy to carry out continuous research and practice, and finally found a good way: that is, to put the food into a wide-mouth glass bottle, plug the mouth of the bottle with a cork, put it in a steamer to heat, and then plug the cork tightly and seal it with wax. In this way, the first cans appeared. Mr. and Mrs. Hu Peisong were received and rewarded by Li Han's young couple, and were also warmly welcomed by the seafarers.

This is simple, in fact, these two people have spent a lot of effort to invent the canned food in the mouth of His Royal Highness the King of Han, Hu Peisong has worked as a worker in a sauerkraut factory, a winery, a candy store and a restaurant since he came to the Han Kingdom. Later, he and his wife Zhang Xiaoman ran a candied food store, and when they were selling fruit pulp, wine and other foods, he found that some of them often went bad, while others did not go bad. He told his wife Zhang Xiaoman about his discovery, and Zhang Xiaoman told his man about one of her accidental discoveries, that is, as long as the food sealed in a glass container is properly heated, it is not easy to deteriorate, and the two of them remembered the huge reward they saw in the Qindao newspaper not long ago, well, there is a door, Hu Peisong kissed his mother-in-law hard, "Gua mother-in-law, there is really yours, I see that there is a door!! In this way, the two began to conduct special research on food preservation methods.

After more than a year of unremitting efforts, they finally succeeded, they processed the food, then put it into jars, put it all in a pot of boiling water, heated it for about half an hour, corked it tightly while it was hot, and then reinforced it with thread or sealed with wax, this technology won the unanimous praise of the imperial supreme couple, and Hu Peisong and his wife also obtained a patent. With the help of Li Chengzong and his wife, they opened a factory to provide all kinds of canned food for the Han army, Hu Peisong's Hu family glass cans came out not long after, and Li Chengzong had a very good relationship with a writer Tian Qing developed an iron cans made of thin tin iron, and also applied for an imperial patent, and because of the continuous progress of technical equipment, a doctor in medical school published a paper in the famous "Nature" journal of the empire, Clarify that food spoilage is caused by bacteria. Therefore, under the coordination of the Li Han government, the canning factory adopted steam sterilization technology, so that the canned food met the food safety and hygiene standards of absolute sterility previously promulgated by the government.

In this way, all kinds of canned food were produced, especially because of the development of the whaling industry in Li Han, a lot of whale meat and water were crushed to make canned meat, and these canned foods were sought after after they were put on the market. It is simply in short supply, and even some merchants from the Tang Dynasty and Persia took this kind of canned food as a luxury and gift, and brought it to them to give away. All of a sudden, this kind of canned food became popular in the upper class of countries such as Datang, Persia, Tianzhu and other countries. Especially when some small nobles and lords' homes hold some parties, if you don't put such a little bit of tin can, you are embarrassed to meet people, and the taste is really good, so everyone flocks to it.

Of course, some people see the greater advantages of this kind of canned food, that is, it can be used in the military, because this kind of canned food is simple to carry, and it is also very convenient to eat, so if each soldier brings such some canned food in the battle, basically the logistical pressure will become much smaller, and these canned foods have a lot of canned meat, don't care what whale meat is inside, meat is meat, and eating meat will have combat effectiveness, right?

When Li Chengzong saw this canned food, the first thing he thought of was to buy it and distribute it to his soldiers, and as far as he knew, those soldiers ate this kind of canned whale meat, and they also thought it was very good, Emma, Your Highness is benevolent, and even gave us the old man this kind of canned food that is called 'full of meat'. Everyone thought that Li Chengzong would eat meat for himself, how could they not be grateful in their hearts. Li Chengzong wants to get it, and the rulers of several other countries can also want it as long as they are not stupid.......

According to Jinyiwei's news, Li Er even used his own private money to buy a lot of canned food, and he even learned from his good nephew Li Chengzong to personally distribute canned food one by one, and it is said that the effect is very satisfactory to Li Er.......

Li Chengzong accompanied Pei Fuer to go shopping, and after wandering for a while, Li Chengzong couldn't help but lament, even if it was an ancient girl like Pei Fuer, the momentum of shopping was not much worse than that of a modern girl, and in the end, a few military reports rescued Li Chengzong.

"Huh? Pei Xingyan was seriously injured? My cousin....... I knew he was going to be underestimated...... Anyway, who made you my cousin, I'll wipe your ass again......" After Li Chengzong saw that Pei Xingyan suffered a big loss in the battle of Baihua Mountain, Li Chengzong was not angry, on the contrary, he saw this as a good opportunity for him to strengthen the quality of officers and defeat the arrogance of the troops.......

Li Chengzong knew that because his own army had won successive battles, from top to bottom, almost the entire army had become arrogant soldiers........
