According to the seller, although this self-made "ID card" cannot be used as a real ID card, the chip in the card can still record relevant information. Whether it is a consumer card in the supermarket or a variety of VIP cards, it is very easy to use. It's a pity that Li Anran doesn't have enough manpower to maintain this system at the moment, so this kind of identity card can only play the role of a generation of ID cards for the time being.

Fortunately, even if there is no way to give full play to the functions of this IC card system, the material of the card itself, as well as the patterns and patterns on it, are not the industrial technology of Datang time and space that can prevent and control.

As for the problem of if someone comes to visit or the relatives and friends of the farmer visit, Li Anran also thought of a solution. All you need to do is get a few sets of radio intercoms, and the "toll booths" built on the road leading from the academy to the cottage will be used as a relay, and the news of someone visiting will quickly spread to the villa. When the time comes, it is natural that there will be an order to let go or block it again.

In the past half a month, Xiaoyao Villa and the academy have made such a big move, not to mention the Tang Emperor Li Shimin, and even the wealthy families headed by the eldest grandson Wuji have also paid attention to it. The difference is only that the eldest grandson Wuji and Cheng Zhijie know the inside story, and they also know how to restrain their subordinates not to mess around. And some other guys who don't know the inside story, after seeing the various benefits and potential benefits brought by the emergence of waterwheels, cement, and brick kilns one after another, there are a lot of red eyes.

All of a sudden, there are a variety of means to inquire about the news, send people to sneak in, buy relationships in private, etc., etc. These actions made by these big families who don't know the inside story are not only clear to the eldest grandson Wuji, but even the Tang Emperor Li Shimin is also very clear, but they all choose to sit idly by and let these people come blindly.

Regarding the prying eyes of these people, Li Anran's reaction at first was very calm. Anyway, the design drawings and production methods of the waterwheel, cement and brick kilns were only in the hands of a few craftsmen who had already signed the death deed. The rest of the helpers, at most, only know the local processing technology. And even if all the processes are taken away, there is no specific fire control, material formula, key parts, etc., it is still useless.

Take the waterwheel that is the easiest to imitate, for example, the core rolling bearings, gears and other components are all steel parts customized by Li Anran in modern time and space. If it is replaced with an ordinary bamboo and wood structure, it does not mean that it cannot be used, but once the waterwheel is too large and the water flow is too fast, it is easy to cause problems due to wear and tear, which will affect the efficiency and cause damage to the car.

As for the cement and brick kilns, not to mention, under the strict guard of the gag order and those guards, the possibility of leakage of specific processing technology and recipes is very low, even if it is not 100% unlikely. Moreover, the most important thing is that whether it is a waterwheel, or a cement or brick kiln, it doesn't matter if someone can give it up.

But as the actions of those big families are getting bigger and bigger, the construction site of Xiaoyao Villa is okay, after all, it is Li Anran's territory, plus the nursing home headed by Cheng Chuhei, no one dares to blatantly mess around. But some things happened one after another at the construction site of the academy, although the matter was not big, but the actions of these big families still made Li Anran very unhappy.

This is unhappy, and it is inevitable that there will be a few feelings when doing things. In addition, Li Anran is now an important person registered with Li Shimin, so he naturally does not have any big scruples about this kind of trivial matter.

Regardless of whether he was peeping on the periphery, or breaking into the inside of the construction site to find information, or relying on his own strength to deliberately come to the door to find trouble, Li Anran's reaction was very simple, and he grabbed it all and called it again. If the electricity does not die, let Cheng Chuhei be thrown to the county government of Lantian County to deal with crimes such as chicken crowing and dog theft. As for those who were electrocuted, I'm sorry, I can only blame you for your bad life.

For this work, Cheng is naturally very reluctant. After all, although the Cheng family is also the founding father, their status in the Tang Dynasty is indeed not low. But once you face so many big families with intricate backgrounds, not to mention any danger, it is more or less a trouble. can't stand Li Anran's use of a good war knife and his promise to help the Cheng family once.

At the beginning, Cheng Zhihei, who was sent to the construction site of the academy to be in charge of this matter, was still a little worried about whether this would cause the anger of Chang'an. Who would have thought that after dealing with a lot of these guys who were in the way and looking for trouble, not only did they not wait for the severe punishment from above, but they waited for a decree, which directly made those big families who were still thinking about whether to retaliate or not to coax them all instigated.

In fact, after Li Anran decided to take action against those big families who were spying on him, he had already sent the process and recipe of waterwheels, cement and brick kilns to the hands of His Majesty Li Shimin, the emperor of the Tang Dynasty, as soon as possible.

As for how the letter was delivered, it was very simple, after the letter was written, it was sealed with a wax seal. After placing it directly on the desk in the courtyard, he shouted around: "I have something important to start playing, and it is a matter of importance, please send it immediately." Then just turn around and leave.

In the letter, Li Anran not only handed over the technology and formula that he did not know how many generations had been eliminated, but also emphasized the importance of the two technologies of waterwheel and brick kiln to benefit the country and the people. As for the technology of cement, it emphasizes the role of military use in road construction and city construction. Finally, he also focused on the question of how much danger these three technologies, especially cement technology, would cause to Datang if they leaked to enemy countries.

After reading this letter, what Li Shimin thinks, Li Anran doesn't know and doesn't want to figure it out. Anyway, these three technologies are not important to me at all, and after they are circulated, they can also verify a certain relationship between time and space travel and historical change by further changing the historical trajectory of Datang.

But what Li Anran didn't expect was that Li Shimin gave a big reward while ordering those big families to be beaten and protecting the academy's project. Among these rewards, it doesn't matter if the money and silk gods and horses arrive, but if those ancient jade pieces that are said to have been passed down from the Han Dynasty are brought to modern time and space, even if the value of their antiques is not considered, the jade itself alone is enough to sell for a good price.

Knowing Li Shimin's reward this time should be a disguised appeasement of the previous events. In fact, as early as when he found out that someone wanted to be unfavorable to him, Li Anran immediately thought that the culprit of this matter was Li Er.

You think, if Li Shimin really doesn't want something to happen to the academy, he will definitely focus on protecting it like he did on the side of Xiaoyao Villa. Since those big families dare to stretch out their hands indiscriminately, they must not have received the warning they should have. Even, this kind of thing is just for someone to let it go, the purpose is to use this little thing to test their bottom line and more strength.

It was precisely because of these thoughts that Li Anran decided to use the "unpredictable" method of electric shock while deciding to give those guys a little color to see.

Electricity was called thunder in ancient times. It has been an object of fear and worship since the beginning of human memory, even in the Tang Dynasty. Therefore, after confirming from the bodies of those injured and dead that someone can actually control the thunder, even if the power of the thunder is really much smaller, it is enough to attract more attention from the Tang royal family and wealthy families headed by Li Shimin.

Without those guys who get in the way and find trouble, Li Anran's small life quickly became leisurely and fulfilling.

Every day, he either stays in the village courtyard to continue his great cause of teaching and educating people, or under the service of the sisters, he enjoys a beautiful life that is enough to make those otaku in modern time and space envious and jealous. And in the name of double cultivation, Su Xiaomei and Xiangyun, who were almost on their own pillows, were separated from each other, and lived a life without shame......

(These two chapters do have some running accounts, but because the wind is too tight in the end, a lot of the content can't be written.) For example, how Su Xiaomei and Xiangyun were pushed down, and how Li Anran let the two daughters serve together, and the plot of being **, etc., I really want to write words, and I can write several chapters gently, but unfortunately, this situation can only pass in one generation at the moment, please forgive me. ）
