When there is something, time always flies quickly, especially for education, it is a long-term thing, this time seems to be faster, but in the eyes of learners, this time is very slow, although they want to learn, but after all, this age is not enough, the progress of natural learning is much slower, but their comprehension ability is much stronger.

However, after four months, it can be regarded as a preliminary meeting of the requirements, all the people have learned the numbers, and even some simple calculations, that is, some words, have also learned a lot, especially those who can read and interpret some texts at the beginning, their learning progress is particularly fast, in this way, the fast can be slow, Yang Heng couldn't help but feel proud of his own arrangement at that time, fortunately brought three assistants in, otherwise Yang Heng would not be exhausted.

However, during the day, Yang Heng was not idle, because when he was looking at the bark of the eucommia trees, he also found some fresh branches of the year, and naturally there were some mature seeds in it, so Yang Heng naturally remembered that he planted it, if this thing is successfully tested, then a large number of raw materials are needed to use it, but it is not possible to only collect wild ones, that is, wild ones are enough, maybe there will be powerful people to control the origin of some raw materials, so if there are a large number of orders, Without raw materials, Yang Hengke will be blind, and seeing these branches, and even these seeds, Yang Heng is happy, maybe he can study the cuttings of these branches, and even the planting of seeds, although now is not the time to take cuttings, but the climate in this mountain can not be compared with the outside, maybe it can be done. Especially Yang Heng found. It looks like the grapes will be transplanted next year. Yang Heng plans to build a vineyard first, which is a bit far away, Yang Heng and the old farmers began to test the cuttings, if successful, he can buy some mountain land to plant a large number of things, after all, Yang Heng does not dare to plant these things on good land now, you must know that Lu Dao, his cotton planting has been successful for several years. But I don't dare to let Li Er popularize, one is afraid that the magnates will use good land to plant, and the other is also worried that Li Er will not promote, and Yang Heng has not had time to tidy up a piece of mountain land to plant, maybe the next cotton thing can also be solved, you must know that no one likes mountains at this time, but Yang Heng does not have the ability to plant mountains, first of all, this water is a problem, although there is a waterwheel. But it can't raise the water too high, can it make a reservoir. It's a joke, if there is no reasonable plan, it is not a blessing, but a curse, you must know how many reservoirs are inappropriate in Yang Heng's previous life, at this time, let the powerful learn this trick, and not directly destroy the environment.

And now, Yang Heng has such an opportunity, first of all, if he builds a water pipe, he can use it himself, and even be able to advertise, when someone realizes that the eucommia tree is related to the water pipe, then Yang Heng's plantation will also grow, naturally Yang Heng will not worry about someone pinching his neck, and even he can buy some raw materials at a low price, you must know that once the raw materials are mastered by the magnates, and there is no output, if Yang Heng buys it, then they will sell it at a low price. However, he may not sell it, and would rather destroy it than sell it, but Yang Heng thought that if he was a powerful family, if he was angry with others, maybe their family would not be far from breaking the family.

But if someone partners to resist Yang Heng's goods, then Yang Heng can not sell them to them, first of all, he still has a lot of partners, as long as he waves his small hands, there are many people who come to hold stinky feet, this is to master the skills, and also grasp the benefits of the right to speak, and even have his own strength, this is the guarantee of his existence in this world, otherwise, it is difficult for Yang Heng to guarantee that he will not be pinched to death, and he wants to play Tai Chi among the powerful, which is not something that this traverser can do. Otherwise, you wouldn't be a time-traveler.

However, the effect is good, when Yang Heng finished the night school, he also got the good news of the old farmers, not only the cuttings of the branches germinated, but also the seeds germinated, now everything is available, only the east wind is owed, and the two Taoist chiefs are also ambitious and promised Yang Heng that in the next year, at the latest, Yang Heng will definitely put forward the glue that Yang Heng said, Yang Heng not only explained some physical knowledge, but also explained some simple chemical knowledge to several Taoist leaders and some blacksmiths, Even those old farmers also listened to these explanations, they at least knew what acidic soil was, what alkaline soil was, and the blacksmith also knew that the biggest enemy in steel was sulfur, and how to desulfurize had become their primary task, that is to say, in addition to the molecular formula Yang Heng did not teach, some simple things he could remember were explained.

Also, before Yang Heng went out of the mountain, he had already promised them that if they did a good job, they could become the offerings of Yang Heng's family, and several Taoist leaders, Yang Heng would build a Taoist temple specifically to let them study the immortals, so everyone was even more excited, as slaves, they couldn't help but be excited, to know that their little lives were held in Yang Heng's palm, Yang Heng said that if anyone was killed, no one would be held accountable, this is the benefit of this era, but Yang Heng is also disgusted with this kind of thing, How can you manipulate people's lives casually, but for the sake of secrecy, Yang Heng has to use this method, and what Yang Heng is waiting for is that it is best to have a country's patent law introduced in the future, so that some patentees can benefit, instead of using human life to restrain them, and even use a lot of secret guards.

"Brother-in-law, it's finally out, it's fun to be fun, but after playing for a long time, it's not fun, fortunately, there is your so-called trial, that's the most fun thing." "Okay, Yuzhang, don't say anything about the test, didn't you say it inside, you must not say anything about the test after you come out, that is, we don't say anything about the things your brother-in-law said, otherwise it will cause some people to covet it." "What about the father, the father can't say it, and the queen mother, the queen mother can't say it." "Ha Luha, let me explain this to you, don't you always feel that there are people around us watching us, there are really people, there are my people in it, and there are also people from your father, do you say that Your Majesty can not know what we are doing inside, so, as long as Your Majesty doesn't ask, it's better not to say it, so as to prevent what you say is not the right time, so that irrelevant people listen. Otherwise, His Majesty may also kill people. "Killing, then I won't say it, I won't say it at any time, only when my father asks, I will say it." "Well, that's right." All in all, Yang Heng's daughter-in-law and a princess befriended, these two are the two princesses with the best hearts in the Tang Dynasty, by the way, maybe there is a princess with a pocket, I don't know when she was born?

"Xuewen concubine, Princess Changle, Princess Yuzhang, and Princess Yang Shu, Your Majesty has a Xuan, please enter the palace immediately to meet you." Yes, Yang Heng and his party have just arrived home, and they haven't sat on their hot butts yet, Li Er's message is here again, although it is not a holy decree, but what is the difference between this and a holy decree, Li Er is calling, can you not go.

"This father-in-law will wait, we will enter the palace with you as soon as we freshen up, butler, take this father-in-law down to rest." Yang Heng gave the housekeeper a look. "This father-in-law, please have tea inside," said him, and a purse was stuffed into the eunuch's hand. The eunuch pinched the purse with his hand, and his face bloomed. "Don't freshen up, don't groom, now Your Majesty is happy, maybe I like to see you like this, this proves that you have something to do during this time, and you are not idle." Yes, this society is so realistic, just a few pieces of gold, let this eunuch say some more words, and also know Li Er's intentions, Li Er is not concerned about Yang Heng's actions during this time, maybe he wants to ask Yang Heng some questions about techniques.

"Alright then, thank you, father-in-law, butler." Okay, I'll give you another purse, for the sake of the face you said so much, Yang Heng didn't want to do this, but what if he didn't, although it was good to travel to this era, but the emperor of this era killed people whenever he wanted, maybe let Li Er find something to deal with, it was better to spend some money to prepare early, and if he knew the state of Li Er, he would have a good way to deal with it, right? (To be continued......)
