Di Renjie guessed correctly, although this gathering had been as low-key as possible, it was still leaked to the emperor. Even, every sentence of each of them was written on paper, and now it is placed on Li Chengqian's desk.

Looking at the information sent by the secret guards, Li Chengqian had a mocking smile on the corner of his mouth: "You really think it's safe to go downstairs." ”

For those who meet secretly, the private room downstairs is indeed a good place, because it is private enough and has a unique soundproof room, as long as there is a guard at the door, people outside can't hear it even if they lie on the wall.

However, just because you can't hear it from the outside doesn't mean it's safe from the inside.

Among the crowd attending the rally, there were three people who were Li Chengqian's people, and even an honest man sitting not far from Di Renjie was one of them.

It's just a temptation, but I didn't expect it to provoke such a big reaction, and the reverse scales of the traditional noble group, even if they are not directly touched, are dangerous.

If it is really exposed, Li Chengqian can imagine what kind of hateful faces these people will show. Although the current situation will not attract the chaotic scene like the end of the Sui Dynasty, it will definitely have an impact on the thriving and prosperous times.

Li Jiyuan pushed open the door of the imperial study and walked in, and there were only two people in the entire palace who could walk in without notification.

"Father, what are you thinking?"

Li Chengqian put away the secret report on the table, threw it into the trash can, stretched out his hand and patted his son's head and said: "Father is thinking about some stupid things, Xiaohong, you remember, no matter what good things are, in front of the entire Datang, there is no comparable value, and any idea of slightly losing the interests of Datang to achieve the goal is stupid!" ”

Li Jiyuan nodded: "My master also told me this, I think it's very correct." ”

Li Chengqian smiled and tried to recall, but he couldn't remember when the master had said such things to him.

Now that he is old, he is bothered by some trivial things all day long, causing him to forget many interesting things from his childhood, especially the interesting things he experienced with his master and brothers.

"You came just in time, you go back to the palace for two days a month, and although today is only the next day, you can go out. Today is the day of the gathering between my father and your uncles, and you just happened to follow it. I heard that you had a fight with Di Yuan a few days ago? This is not good, from your master's point of view, you are his senior brother, you have to let him a little when you should let him. ”

Li Jiyuan nodded, and then diligently helped his father take off his dragon robe. He knew what day it was, and the reason why he came to his father was to get a ride out of the palace.

He was used to living with his master, and now that he returned to the palace, he felt uncomfortable.

The queen mother always made him motivated, and he was favored in front of his master and father, and the palace maids and eunuchs were full of fear when they saw him.

In comparison, Shigong's place is much more interesting. In the past, after missing his father and queen mother, he longed to go back to the palace for a few days every month, but now, he was not satisfied with even two days.

There was no emperor to travel, and under the escort of more than 100 guards, Li Chengqian and his son left the palace in a very ordinary carriage.

Today is the annual teacher's meeting day, so Leng Rui also asked for leave from the Academy of Literature and waited for the arrival of the senior brothers and sisters at home.

Li Tai's family has always been casual, Feng Yu didn't need to be accompanied by her husband, she took the child to the door, and not long after Li Tai also walked into the mansion in an embarrassed experimental linen clothes, he didn't visit the master directly, but went to the housekeeper to change clothes first, just like his own family.

When Leng Feng arrived at the bath, he didn't go in to see Li Tai, but first picked up Li Tai's clothes and smelled them.

He doesn't have any disgusting hobbies, but he is very familiar with this faint sour smell when he dismantles the battery as a child. Not surprisingly, Li Tai did study in the right direction.

Walking into the bath, Leng Feng brought Li Tai a pot of wine to relieve his fatigue.

After thanking Master, Li Tai, who had lost a lot of weight, leaned on the edge of the bath and said, "Master, you always told me that physical chemistry is a twin, and both are indispensable. I didn't care about it before, but now I don't care about it. Those guys who are simply studying physics, after two years of tinkering, have not made any progress, but they have studied the glowing lamp. And those who tinkered with chemistry quickly found the right direction.

They overlapped copper and zinc plates, piled them up with cloth soaked in salt water, and connected the two ends with wires, which actually generated an electric current. Since this principle can generate electricity, if you work backwards, you will definitely find a way to store electricity. Now they're working on an acid, and it's going well. I believe it won't take long to get the stuff out of the storage point. ”

Leng Feng nodded and said to Li Tai: "Although Master remembers it and is embarrassed to say this, their direction is right, that is, they need to continue to study and improve. ”

Li Tai said excitedly: "I have always believed that electricity must not be a simple force, before I reversed the generator, found that electricity can be converted into power, if the power is large enough, the motor is good enough, it is not a problem to replace things driven by steam engines with electric power." Steam engines also need to consume fuel, but this is not the case with electricity, as long as the generator is mounted on the windmill, the wind can bring a lot of electricity! ”

I didn't dare to imagine that Datang was full of neon lights, Leng Feng found that in fact, the development of science is lacking one opportunity after another, as long as the opportunity is provided, human beings, a species full of curiosity, can dig out all kinds of truths between heaven and earth.

And what about the ancients? They are not lacking in curiosity, and they are more able to keep their hearts in the midst of all kinds of earthly temptations, and concentrate on studying what is really beneficial to Datang, rather than spending a lot of time researching eating, drinking, playing, and entertaining.

Involuntarily patted Li Tai, Leng Feng said: "I won a lot of gold coins from your father and emperor that day, and I will take them away when you leave in a while, and those who have contributed to the study of electricity should also be rewarded." ”

Li Tai cracked his teeth and smiled: "If you can get a compliment from you, they will be able to dance, but since you want to add a monetary reward, then the elder will not dare to resign, and the apprentice will thank the master for them first." ”

Leng Feng nodded, not feeling reluctant. This kind of pure scientific research needs support, and if this support is purely verbal or paper, it is a bit too chilling. Words of encouragement a thousand times are not as real as gold coins.

"This kind of thing will become a permanent practice in the future!"

I don't know when, Li Chengqian also got in.
