Yang Guozhong was not very satisfied and left the Right Prime Minister's Mansion, but this trip was not for nothing, and he still learned some things, for example, he already knew more about the crown prince Li Heng, and knew that this guy was a turtle with a shrunken head, shrunk in his shell all day long, making people unable to put his mouth down.

Another is that we must try our best to cultivate a prince who can replace the current crown prince, so as to replace the crown prince at the right time, as for which prince to choose, it depends on his own vision.

In history, Yang Guozhong has always been the vanguard of opposition to the crown prince Li Heng, not only when he framed Li Heng with Li Linfu, he acted as a pawn, and after Li Linfu's death, he also kept suppressing Li Heng, if it weren't for Li Heng's forbearance and forbearance, he was a turtle with a shrunken head, it is estimated that he would have encountered an accident a long time ago, in addition, when Xuanzong proposed to hand over the world to the prince and Xiangguo to take care of, Yang Guozhong was also strongly opposed, and even, even his sister Yang Guifei tried his best to dissuade him, for fear that the prince Li Heng would really take the throne.

Of course, this is just a temptation of Xuanzong, how could Xuanzong, who is extremely obsessed with power, hand over the power in his hands to his son? How can he do whatever he wants, what he wants is that everyone around him is loyal to him, and Yang Guozhong strongly opposes the crown prince in power, and he is also sincere, he is afraid that after the crown prince Li Heng takes power, with the gradual improvement of his prestige, there will be more and more cronies and supporters, and his life will become more and more difficult.

"Father, when the child came back just now, he seemed to see Yang Guozhong, what did he come for?"

Li Xiu went home after handling political affairs, because his father was not in good health and was the right minister of the court, so colleagues in the same position would naturally share more business, so as to free up more time for Li Xiu to go home to serve his old father, and the human touch was quite strong.

Li Linfu was resting with his eyes closed, and said softly when he heard the words: "It's for the prince's affairs, he came to ask for advice, His Majesty is sick, which makes him nervous." ”

"Father thinks that Yang Guozhong can deal with the prince, can he really bring the prince down?"

Li Xiu asked suspiciously.

Li Linfu sighed and said: "The prince seems to be timid and afraid of things, but in fact he is thoughtful, not much worse than the ancient Goujian, and His Majesty does not seem to have the intention of abolishing the prince, and wants to deal with him, but his father can't do it, Yang Guozhong can't do it even more, if this fool doesn't know how to restrain himself, I'm afraid that sooner or later he will die at the hands of the prince!" ”

This worry is not unreasonable, Yang Guozhong in history did have no way to take Li Heng, just like a lion seeing a turtle, there was no way to say it anyway, and in the end, during the Anshi Rebellion, the prince planned the Ma Weipo Incident, killed all Yang Guozhong's family, and even killed the concubines around the emperor, and finally took a bad breath.

"Since Yang Guozhong can't count on it, how should we deal with ourselves?"

Li Xiu asked.

Li Linfu said helplessly: "Count on him, don't even think about it, it's not bad if he doesn't rush up and bite us to death, can you still expect him to help us?" Ay! Let it be! ”

After saying that, I closed my eyes and recuperated, and I didn't want to continue talking.

Yang Guozhong, a traitorous minister, is still thinking about how to frame the prince, Li Linfu is thinking about what is behind him, and Li An is thinking about how to take the emperor's grandsons to play in the mountains where he becomes.

The emperor and grandson are all baby bumps, once there is any personal accident, the consequences are not generally serious, although Li An will only receive some responsibilities at most, and it is the attendants and guards who suffer and are beaten, but as long as there is an accident, his face will not be able to hang up, so if the accident can be avoided, it must be avoided as much as possible.

The environment of the mountains and forests is complex, the road surface is not as smooth as in the palace, and from time to time you can encounter raised stones and dead tree roots, which can easily cause people to fall, and once you fall, it may lead to injury, and the emperor and grandson are injured, so you have to go.

Therefore, before leaving, it is necessary to prepare protective gear for these emperors and grandchildren, and the armor worn by ordinary soldiers is too heavy, so that the emperors and grandchildren wear such heavy armor, their small bodies will be crushed, besides, many emperors and grandsons are still relatively young, and their figures cannot reach the size of the armor, so they can't wear it at all, and it is extremely unrealistic for them to wear armor to play outside the city.

But it is necessary to play, and the armor cannot be worn, and the emperors and grandchildren cannot be injured, which puts forward higher requirements for Li An, and must immediately invent and produce a lightweight protective gear, which can make the emperor's grandson not injured when he falls, and it is not very heavy, in addition, because it is the emperor's equipment, so, it must also be good-looking and decent, if it is too ugly, it will lose the royal face, and the emperor will refuse to wear it.

What Ang Lee can think of, the lightest protective gear is the skate protective gear system of later generations, however, it is necessary to make certain improvements on this basis, for example, the style of the helmet can be improved, so that its heel is more in line with the aesthetic standards of the Tang Empire, and the problem of knee pads and wrist pads is not big, after all, Datang's clothing has long sleeves on top and skirts below, and knee pads and bracer pads are difficult to see from the outside even if they are worn on the body.

But knee pads and wrist pads must be light and comfortable, if it is uncomfortable to wear, the emperors and grandchildren will also have resistance, and the standard of comfort is not too heavy, let alone affect the freedom of movement of the leg joints and elbow joints, otherwise, it will lose the meaning of the protective gear.

The research and development of the helmet should use the lightest and high-grade materials, and the weight must not be very high, otherwise, after wearing such a helmet for a long time, you will feel neck pain, which is very bad.

It is a very good idea to take a lighter sponge material, but if it is a pure sponge, there will be no protective effect, or there is a hard protective material, a hard and light hard protective material, which is undoubtedly a new type of synthetic plastic, at least it cannot be made of steel, otherwise, it will be too heavy.

Fortunately, after so many years of industrialization, plastic can still be produced, and it can already be used to produce some industrial supplies, for example, various machinery industries need plastic and rubber materials.

In order to further reduce the weight, even if the material is plastic, some hollow styles must be designed, so that the weight can be further reduced, and at the same time, the strength of the helmet will not be too damaged.

Although there are still many problems to be solved in the Wanli Transsion Project, there is no difficulty in developing this kind of protective gear for Ang Lee, and it can basically be completed quickly.

"Li Shilang, this is also related to the Wanli Transsin Project?"

A subordinate looked at the drawings drawn by Li An, as well as various technical parameters, and asked curiously.

Li An didn't answer directly, and directly ordered: "You don't have to worry about this, you have to make these things as soon as possible, the sooner the better, and complete this task at all costs." ”

"Yes, Li Shilang."

The subordinate answered.

Li Ang made a good protective gear, and then continued to solve the problems such as the tuning fork encountered in the Wanli Transsion Project, and overcame the difficulties little by little, and together with many researchers, most of the problems were solved.

Li An, who was tired for a day, when he returned home, found that there was a guest at home, it was Yan Ruyu's uncle Yan Zhenqing, a great calligrapher, and a very upright Qing official.

However, although Yan Zhenqing is an honest official and has outstanding ability, he has not been reused, after all, he is a person who is not good at drilling, and he doesn't know who to please anyone, for example, his relationship with Li An is already so close, and it is still okay to ask Li An for help, but his arrogance will not agree, he would rather always do nothing in a very low official position than ask for help.

And this time I came to visit Ang Lee and the little baby at home, and I also brought some sweets and other snacks to make the children happy.

"Oops! Uncle is here, I haven't seen you for a long time, and I miss it so much! ”

As soon as Li An saw Yan Zhenqing, he approached him affectionately.

"Haha! Uncle misses you too! Your next trip to the south, it's been nearly two years, and you miss your uncle to death. ”

Yan Zhenqing said with a smile, and was also very enthusiastic.

"It's just to serve the imperial court, it's okay to work hard, and my uncle has worked hard all these years."

"It's all as it should be, it's not hard, it's not hard, hahaha!"

After greeting each other for a while, the two talked about the current situation.

The treacherous minister Li Linfu is about to die, but Yang Guozhong, who is about to succeed him, is not as good as Li Linfu, he is simply mentally retarded, which makes a loyal minister like Yan Zhenqing very worried in his heart.

"Uncle don't worry too much, Yang Guozhong's ability is mediocre and he can't set off any big storms, besides, isn't there still me?"

Li An said confidently.

Yan Zhenqing sighed and said: "My nephew's prestige is naturally higher than Yang Guozhong's, but what Yang Guozhong is about to grasp is the power of the imperial court, and you are nesting in the R&D center all day long to work on machines, so you can't affect him!" ”

Obviously, Ang Lee did not like to participate in court politics, and rarely participated in court politics, and had little influence on the policies of the imperial court, but the impact on industrialization was very large, and almost the entire imperial court listened to Ang Lee.

And what Yan Zhenqing is worried about is that after Yang Guozhong takes control of the political affairs hall, he will try his best to squeeze out people who are not all the way to him, and vigorously develop his henchmen, so that the entire court will be filled with his henchmen, so that his position can be more stable.

Li An said with a smile: "Uncle is too worried, although I don't like to participate in court politics, but I still have a lot of influence on the court, as long as I want to check and balance, there is no one I can't check and balance." ”

"Alright! Uncle naturally believes in you, I don't know what happened recently, Your Majesty is sick, all the kings have moved, but His Royal Highness the Crown Prince has always refused to see us, and he is not even willing to communicate with us, I haven't seen the Crown Prince for several months. ”

Yan Zhenqing said suspiciously.

Li An hurriedly said: "Uncle is too worried, His Royal Highness the Crown Prince is just to protect you, it's not that he really doesn't want to see you." ”

"I'm just an eight-rank Beijing official, and I don't have military power in my hands, even if the prince sees me, what can I do? Could it be that there are still people who dare to frame the prince for rebellion. ”

Yan Zhenqing said.

"Uncle is not a high position, so naturally he will not attract the attention of others, but after the prince meets his uncle, what if his uncle goes to see someone else? The framer will find an excuse. ”

Ang Lee said with a smile.

Yan Zhenqing patted his head and said, "It's true, isn't my nephew a high-ranking official?" If you see the prince and come to your nephew's house to sit down, won't you be framed, these hateful villains have no other skills, and the ability to frame them is self-taught, hum. ”

After speaking, he snorted angrily, which shows his hatred for these people who frame power.

Subsequently, Yan Zhenqing talked with Li An about some topics of the imperial court, and it can be seen that Yan Zhenqing, who has a small official position, is still very concerned about the imperial court, he is the firm support of the prince, he believes that only if the prince is stable, the Tang Dynasty can be stabilized, if the prince's position is not stable, the Tang Dynasty will be easily unstable, and even, the country may fall into chaos.

Since ancient times, anyone who adheres to orthodoxy and supports the crown prince is basically a loyal minister, and only the villain will provoke the struggle of the court, thus plunging an empire into endless civil strife.

And an empire, the most serious civil strife, is not a peasant uprising, nor thieves and bandits are rampant, but from the fierce struggle within the imperial court, as long as the internal strife within the imperial court is endless, it will cause extremely terrible internal friction to an empire, which will lead to the demise of the empire.

The most serious internal strife is undoubtedly the era of Wuhu Chaohua, that era is really terrible, first the rebellion of the eight kings within the Jin Dynasty, the government is a chaos, and then the various regimes are rotated on the stage, among them, since the death of Shi Hu in the Later Zhao Empire, the emperor has been changed extremely frequently, almost every year to change the emperor, not to mention the ministers, whether it is the emperor, the ministers, or ordinary people, no one can predict what bad luck they will encounter tomorrow.

Since the founding of the Tang Dynasty, every time the heir ascends the throne, it is accompanied by bloody storms, and there is no emperor who easily sits on the dragon chair, and even, there is a female emperor Wu Zetian, who can be said to be unprecedented and unprecedented, and even, has become an example for later generations of feminists to promote their rights and interests.

The women of later generations, all of them have a dream of being an empress, arrogant don't want it, they will turn their faces if they don't agree, who made them all empresses? Coupled with the fact that there are more men and fewer women due to a certain policy, this makes these women even more arrogant, it is really too difficult to serve, Li An in the previous life, would rather be single for the rest of his life, than serve these empresses, and his life is not as good as that of a slave.

After some comfort from Li An, Yan Zhenqing's mood is much better, after all, although there are traitors in the Tang Dynasty who control the government, there are still virtuous ministers like Li An, in addition, although the prince has been suppressed, he is also a person who can endure humiliation and burden, and sooner or later he will defeat the traitors and ascend to the throne himself.
