Li Yi retreated again, to be precise, he retreated to study glass-making, this time he made up his mind, if he didn't succeed, he would play dead, the most fucked up thing is that he only has one month, now the solar calendar is October, but there was no solar calendar in ancient times, so, according to the lunar calendar, the end of August and the beginning of September. In other words, there are still three months to go before the Chinese New Year, and he has to develop the glass within a month so that he can catch up with the latest planting time.

Li Yi also gave Bingyu some tasks before the retreat, that is, to persuade tens of thousands of villagers around Jinling County to plant this kind of vegetable greenhouse, Li Yi means that Li Yi came out of the capital to build the shed, they only need to pay some labor, if they are not successful, they just pay some labor, but once successful, Li Yi can share thirty percent of the profit to them, don't underestimate this single profit, in ancient times, off-season vegetables are definitely profiteering, once successful, this is a lot of wealth. Moreover, Li Yi also gave them another choice, that is, they can choose to pay wages, that is, they go out of the land and labor, and Li Yi pays the wages, but in this case, once they succeed, they will not be given a little profit, and if they want to get rich, they must know how to make trade-offs.

These Li Yi and Bingyu are very clear, and Bingyu's tasks are not only these, she also has to make preliminary preparations, such as the preparation of bricks and cement, he needs to transport all the things that may be used to various villages in advance, to ensure that Li Yi can use it directly, when Lin Jiang came, he brought some craftsmen, these people are craftsmen who can make cement, so these things can be handed over to them, Bingyu only needs to make plans, and the rest is the preparation of some straw curtains and other things. These things seem simple, but they are quite tedious to do.

However, Bingyu is really energetic, she never dreamed that Li Yi would give her such an important thing to do, she has long envied Changle and Xue Yan and others who can do something meaningful every day. But she is just a girl, her task is to serve Li Yi well, if Li Yi does not propose, although he also yearns to do something meaningful by himself, but he can also see it.

But now that she has this opportunity, then he will cherish it more than anyone else, so this girl has taken out two hundred percent of her strength, and she seems to be more determined than the general's military order, Li Yi smacked his tongue for a while, and at the same time there was some indescribable feeling in his heart, Li Yi knew that this girl had always been lonely and boring, and it seemed that she would have to find more things to do in the future.

After instructing Bingyu's task, Li Yi asked people to go to Yangzhou to help him find some people who can make glass, although the shipping of Datang is very poor, but there are still many Western people who come to Datang by ship, so there will definitely be such people in Yangzhou, so Li Yi can only cast a wide net and fight luck, he knows that this kind of talent is rare, even in Chang'an, it may not be found, let alone Yangzhou, but it is still necessary to find it, what if?

In the end, Li Yi took Xie Junhao, Lei Gang and twenty generals to find an official kiln for refining ceramics, and a simple transformation can do the preliminary work.

Li Yi also doesn't know much about refining glass, but he still knows the most basic steps, these can't help but make him a science student, although he was a cynical rich second generation in his previous life, but he also graduated from college seriously, after all, exploration requires a lot of special gadgets, so he does general things by himself, so it is more convenient to use.

But modern things are different from ancient times, and he uses lathes and milling machines to make steel pipes in modern times. What now? He only has a wooden bed, and the glass he uses is ready-made, he has never done it himself, just out of curiosity, he has seen others do it, and now he is only a little impressed, so he can only cross the river by feeling the stones.

Ingredients (quartz sand, limestone, soda ash, boric acid, etc.), melting, artificial blowing and shaping, etc. This is the general step of refining glass, it is easy to say, but it is difficult to do step by step, the most difficult thing in this is about temperature control, each step has a specific temperature point, high or low will not work, these can only rely on Li Yi himself to experiment, so, a month's time, the task is really not generally difficult. However, Li Yi is like this, the more difficult the task and the greater the pressure, the more energetic he is!

Li Yi retreated to make glass, Chen Mo and Su Pan had already set off to find Zhancheng rice, Jiang Lichen was busy training the remaining fifty-odd generals to think about the movements of Jinling City at the same time, Bing Yu also began to take the dozen or so family generals bodyguards given by Li Yi to wander around and began her road of persuasion, Lan Wei had collected a large number of rapeseeds, and was now busy raising the business alliance to open a third branch alliance in Jinling, and Lin Jiang had also arrived in Yangzhou and was preparing for papermaking.

Jinling is now calm on the surface, but in fact, the people around Li Yi are already busy, however, when they succeed, it will shock the entire Tang Dynasty.

......

Chang'an, the palace of government.

Li Er and Empress Changsun are teasing Li Zhi and the little son, these two little guys are already six years old, and they have reached the age of studying, but they are still very playful, and Li Er is also very fond of these two children, so he let them play.

"Your Majesty, Boy Yi has been doing this for more than a month, right?" The eldest grandson, who was teasing her little son, suddenly raised her head and asked.

Li Er's heart moved, and he sighed a little. "Yes! It's been more than a month, this kid, not long after he came back from the expedition, he left again, this Chang'an is not there, it's really a lot less fun! ”

"Hehe, Your Majesty misses him?"

"Cut! Will I miss him? Joke! ”

Empress Changsun pursed her lips lightly, smiling slightly, she knew that Li Er was just hard-mouthed, and for the secret fight between Li Yi and Li Er, Empress Changsun only shook her head helplessly, just like the battle of two children, they refused to take a step back. But this is also the tacit understanding between the two is getting more and more sufficient, although Li Er can't say that he has completely let down his guard against Li Yi now, but at least he has regarded Li Yi as his own, but because Li Er is the emperor, the vigilance that should exist will always exist.

"I don't know how this kid stayed in Jinling? This child has been fatherless and motherless since he was a child, and it was Wang Daochang who raised him from childhood to adulthood, and Wang Daochang's death must have hit him very hard this time, right? ”

Li Er also sighed slightly. "The blow is indeed not small, I heard Xuan Ling say that after Wang Daochang died, this kid knelt in front of his master's grave for three days and three nights, and he didn't even eat, and the whole person lost a lot of weight. Alas! This kid is not easy! ”

"And this?" Empress Eldest Sun suddenly felt a heartache, because of Changle's relationship, he had already regarded Li Yi as his son, plus Li Yi was already fatherless and motherless, and he was indeed liked, so Empress Eldest Sun really loved Li Yi, and now I heard that Li Yi had suffered such a big crime.

"Hehe, but this kid is not so easy to be defeated, the talent who can be favored by my Li Shimin must have great wisdom and perseverance. This blow can't stop him! ”

"Yo, Your Majesty, haven't you always looked down on him?" Empress Eldest Sun said with a smile.

"Ahem, Guanyin, isn't that all a joke? Seriously, I really have to admit that this kid is a rare genius in a hundred years, let's not talk about his military exploits, let's talk about what he did in Chang'an, a small business alliance, stunned to drive the development of Chang'an's overall business, now Chang'an and Luoyang and other places are all based on business alliances as a template, and even a considerable number of groups have appeared, that's all, you can make Chang'an's business tax at least three times this year. Moreover, since there is a business alliance, these gentlemen in the capital seem to be reborn, they are busy with their own affairs every day, and they are becoming more and more cultivated, the Confucian merchants that Yi boy said, I also saw a shadow in them, I didn't listen to Xuan Ling's nagging, saying that their sons were sensible, knew filial piety, and had a future, they were all old and relieved! ”

"Is this kid's business alliance really so powerful?" Although Empress Changsun knew that Li Yi had done a lot of things, and had helped Li Er come up with a lot of ideas, and even had a lot of military exploits, she didn't know what it was, and today was the first time she heard Li Er say it, but it was just the tip of the iceberg, which had already shocked him, she really didn't expect that Li Yi would actually do such a big thing. "Is this kid really so good?"

"Besides, this kid has a lot to do! Although he has only been in Chang'an for one year, he has brought earth-shaking changes to Chang'an! ”
