Li Chengqian's bizarre behavior is actually a backlash brought about by being an emperor. In any case, he became the emperor with a hint of resistance, so after unloading the emperor's errand, he became a bit nonsense.

Just like Emperor Taizong at the beginning, the entire Tang Dynasty was tolerant of Li Chengqian's Hu Lai. An emperor who has continued to live for twenty years, or even further, will be tolerable in whatever he does after retirement.

A year after Li Jiyuan became emperor, Leng Feng was even more free. In this year, except for the first court meeting, Leng Feng only showed his face at the annual court meeting, and never interfered in court politics.

As long as they don't play with their prestige, people still respect the auxiliary king. This one is also a veteran of the Three Dynasties and the founder of the Academy of Literature, so the necessary respect is indispensable.

When the role of the emperor became more and more diluted, Li Jiyuan finally no longer had to be trapped in the palace, and he was able to walk out of Chang'an and wander around. Or go to my father to do my filial piety, or go to the emperor's uncle and brother to see the excitement.

During this period, I don't know what Li Chengqian said to Li Jiyuan, anyway, Li Jiyuan came to the world's manor more and more often.

Knowing that Li Chengqian planned to let his son choose a commoner's concubine to try, Leng Feng didn't intervene. When Li Jiyuan gets married, he, the auxiliary king, will be able to retire honorably. Being in a position where you can easily be suspected of rebellion is not the same thing after all.

Aside from the court, what interests Leng Feng the most is Li Tai's laboratory and the testing ground of the Thunderbolt Division.

After the engine was developed, Li Tai ruthlessly studied the knowledge of electric lights and electromagnetics, and delusionally thought that he would make a leap forward in Datang's science and technology again with his own strength.

After visiting Li Tai's laboratory, Leng Feng didn't say anything, just told Li Tai when the electric light was researched, and he would power his house first.

As long as the research is in the right direction, it is only a matter of time before electric light appears. Before this, Leng Feng had never imagined that he would be able to see electric lights in his lifetime. However, with the unremitting efforts of Li Tai and others, the fantasy may not be unrealized.

Three years is actually a very short time, not long after the electric light research of Li Tai's laboratory came out, Li Jiyuan announced his wedding, and the canonized queen was the daughter of a Liu family in the manor of the world.

The people are extremely supportive of such a thing, which shows that the royal family really looks up to the commoners. However, the noble group is not very happy. The emperor's behavior obviously conveyed a signal, that is, in the future, the channel for Xungui to expand his family's power through marriage with the imperial family was completely blocked.

The world has been peaceful for so many years, and maintaining the status quo in the power circle is the most stable way.

There are those who acquiesce, and naturally there are those who try to oppose it. But before these opposing voices could be spoken, they were frightened back by Leng Feng.

Chu Suiliang is also dead, and now the two people with the highest rank in the Tang Dynasty are the old immortal Cheng Yanjin and Leng Feng.

In front of the auxiliary king, even if there is even a word "no", they dare not say it at will.

After settling the matter promised to Li Chengqian, Leng Feng relieved himself of the errand of the auxiliary king and completely returned the court to the young man.

The seedlings of decentralization and the people have sprouted, and if this continues, they will grow and blossom one day.

The nobles of the Zhenguan period, in addition to Fang Yiai and others who still guarded the title of "Guogong", many have begun to decline. Coupled with the peace of the world, it is even more difficult to obtain a knighthood. The influence of these wealthy families will eventually fade in the circle of power.

When the commoners occupy a place in this circle, it will be the time when Li Chengqian's idea will be completely realized.

A piece of paper, written and torn off, written and torn again.

Leng Feng has been in a tangle for three days, and during this period, Li Chengqian has to come to visit every day.

On the fourth day, Li Chengqian finally couldn't hold back his curiosity and went to his master's desk to look at the things on the paper.

He knew everything, but he was confused about what "aggregation" and "fission" were.

"This thing Qingque may be able to understand a little, you can forget it."

Leng Feng didn't stop Li Chengqian from watching, or rather, now he hopes that Li Chengqian will help come up with ideas.

After completely retiring, it is impossible to say that he will no longer worry about Datang. In the end, it is his own destiny, although Datang is now the most terrifying country on the planet, Leng Feng still does not want Datang to be overtaken in the future.

Especially after Hao Wencai and Fan Fall passed away one after another, Leng Feng couldn't help but worry about the future.

Nuclear bomb.

This is a demon that only exists in Leng Feng's mind, and with the current mainstream research direction of Datang's science, I am afraid that it will not be studied here in a short period of time. The ground-level thunder of the Thunderbolt Division and the gunpowder weapons such as the thunder cannon that appeared later are already the most terrifying things in the world. Leng Feng was wondering if he was right to leave the nuclear bomb in his research ideas.

With the ability of the current group of madmen in the scientific community, as long as their thinking is put on the right track, the appearance of nuclear bombs may not take more than a hundred years.

In the end, Li Chengqian still saw the phrase he understood on the paper - "heaven-level thunder".

Although he was prepared, he still took a breath when he learned that Master was preparing to write down the research method of Heaven-level Thunder.

Although he knew that the master knew how to make a heaven-level thunderbolt, Li Chengqian did not take the initiative to ask. Because the current force of Datang is enough, even if there is a heaven-level thunder, it is just the icing on the cake.

"Do you want to leave a legacy for future generations?"

Thinking of the master's entanglement, Li Chengqian easily guessed the master's thoughts.

Leng Feng nodded: "That's right, I always want to leave something, but this thing is really dangerous, and I don't know if it's good or bad to stay." Power can always stimulate people's ambitions, Datang's current territory is enough, if someone has the intention of continuing to expand in the future, I am afraid it will be a curse rather than a blessing. ”

Li Chengqian suddenly picked up the pen, handed it to Leng Feng and said, "Master, if you want to stay, just stay, we don't need to worry so much about the affairs of the future generations." Leaving a guarantee is already the ultimate that your ancestors can do, and there is no need to think too much. ”

Looking at Li Chengqian's determined gaze, Leng Feng finally nodded his head and wrote down everything he still vaguely remembered on the paper.

The words on the pile of paper would eventually be carved onto porcelain, which would then be sent to the research institute and cordoned off. It cannot be opened until the time of the death of the country.

After leaving this last thought, Leng Feng completely lost his concern for Datang. Although he is now less than seventy, his heart is completely calm....

Time passed quickly, and when Leng Feng was shocked to realize that the person who served him had become Xiao Xiaoyuan, he remembered that he was already in his nineties.

Age was a little concerned at the beginning, but when it was really close to death, it was no longer so concerned.

Every day when he woke up, Leng Feng felt the boredom emanating from his bones.

Li Chengqian passed away in the end, and Cheng Yanjin, Sun Daochang and others also passed away. Even the next generation of Fang Yiai went to another world not long ago.

Walking to the empty dining table, Leng Feng sighed.

Liu Shuwen and Xiaocai couldn't beat time in the end, obviously they had an appointment to be together for a lifetime, but now it seems that it is themselves who don't count.

Xiao Xiaoyuan is only twenty-five this year, it was when he was young, after drinking a bowl of porridge, Leng Feng put down the dishes and chopsticks, and said: "I don't know what your father thinks, among your brothers, you are the smartest, and you don't want to be an official, but you come to serve me, a bad old man." ”

Xiao Xiaoyuan said with a smile: "At the beginning, grandpa was your housekeeper, and my father was also your housekeeper, but now that my father has passed away, the only people in our family who can continue to serve as your housekeeper are naturally the only ones in our family." Being an official is just a reputation, and now serving your work, but others can't blush. ”

Seeing that Xiao Xiaoyuan insisted, Leng Feng didn't say anything more.
