At the court the next day, not only did the new commercial tax law be announced, but also ordered Lingnan Feng Ang to attack the Nanban, the reason for which was that the Nanban did not respect the Tang Dynasty and did not pay tribute to the court for so many years.

This reason is very far-fetched, but no one opposes the emperor, because Fang Xuanling and others have not reacted, that is, Wei Zheng, who has always opposed the sword soldiers, did not come out to admonish the emperor this time, which means that there must be an inside story!

The hard work of the past three years has now borne fruit, and because of this credit, Fang Xuanling and Leng Feng each received a reward of 10 million gold and 100 silk horses. Leng Feng, in particular, actually got an official food of 1,000 households for the first time.

You must know that before this, Leng Feng did not have a food town, the Duke of Xi, and there was no duke of the country called "Xi" anywhere. Without a fief, there is naturally no food estate, but this time Li Shimin divided the world manor and the surrounding area of the Academy of Literature into his food estate.

In addition, the area around the Academy of Literature was also rezoned as "Shengshi County", which belonged to Chang'an County like Chang'an, Wannian, and Lantian.

Taking a county as a food, then Leng Feng's Guogong has become the treatment of the county duke, such a contradictory approach is really a bit absurd.

Leng Feng studied for a long time and couldn't figure out what Li Shimin wanted to do, so he simply ignored it and returned to the busy life of the military department.

The morning was his regular work on the steam engine, and the afternoon was spent studying the steam engine with Li Tai.

The sealing of the steam engine studied by Li Tai was a very serious problem, and without rubber, Li Tai used cowhide.

Although cowhide also has a certain flexibility, it is still not suitable for sealing. In the absence of rubber, the study of the steam engine is to accumulate the experience of failure in the future.

The principle of the steam engine is very simple, but when it comes to things such as mechanism pressure, it is extremely difficult, and with the help of the Gong family, it took a long time to rebuild a new model of the steam engine.

Looking at the slowly moving parts in the smoke, Leng Feng said helplessly: "No, the power consumption is still too large, this is still related to poor sealing, let's study the steam engine now, at most we can explore how to set the external structure, and the internal steam engine still can't be used!" ”

Li Tai said helplessly: "However, if I don't study the steam engine, I have nothing to do recently!" ”

In the past three years, Li Tai still secretly researched airplanes, but none of his planes could fly into the sky, so he could only change to research steam engines.

Leng Feng patted Li Tai on the shoulder: "Qingque, Master knows that you want to create your own achievements, but you can't always stare at some ethereal things!" When Master left Chang'an, he put the composition of a seeder on his desk, and you definitely saw it, but why didn't you study the seeder? ”

Li Tai scratched his head: "The seeder is the kind of thing that cultivates the land, how can it be as important as the steam engine?" ”

Leng Feng patted Li Tai: "This is not good, not to mention that farming is the most important thing, it is better to invent and create, and it is also in line with the reality of life." If you study the sowing engine, not only will you be worshiped by the people, but you will also be able to help your father and emperor gain the love of the people, why not? ”

Li Tai thought about it, only to find that this was indeed the case, he called his team and said to Leng Feng: "Then, Master, I went to study the seeder, when the rubber is ripe, you must urge Feng Ang to send it to Chang'an!" ”

Looking at Li Tai who ran away, Leng Feng shook his head.

Li Tai, this guy, if he had the opportunity to shoot the emperor's father's ass, he would never let it go, so Leng Feng said the above words. Sure enough, this guy immediately gave up the steam engine and went to study the seeder with peace of mind.

After leaving the scientific research institute, Leng Feng decided to go to the academy of literature to meet a prodigy from Taiyuan, Bingzhou.

At the age of seven, he completed his studies at the Academy of Letters and was admitted to the Academy of Letters.

However, what attracts Leng Feng more is his name.

Di Renjie. The word Huaiying.

Detective Di Renjie, one of the most famous prime ministers in history!

can fight with him, it is estimated that only the iron-faced selfless Bao Qingtian is this....

This needs to be seen!

Through the window of the Academy of Literature, Leng Feng saw Di Renjie sitting on a raised stool and a group of young people in the front row.

At the age when his peers were still learning to grasp the pen, this guy was admitted to the Academy of Letters, and it seems that some people are really born smart!

When the bell rang for the end of class, Han Chongwen led Di Renjie out and introduced him: "Haven't you always been curious about what Gong Xi Guo looks like?" That's it! ”

Di Renjie looked Leng Feng up and down a few times, and said suspiciously: "Didn't you say that Gong Xi is the richest man in the world?" Why is he so skinny? ”

Although his knowledge is enough, his way of judging things is still so childish.

Leng Feng squatted down and said to him, "Who told you that a rich businessman must be a fat man?" I'm still a general, why don't I have a beard?"

Di Renjie scratched his head, and then said: "I heard that the Duke of Xi Guo is the smartest person in the world, if you want to prove that you are the Duke of Xi Guo, you have to answer me two questions." ”

What Han Chongwen said is not enough to explain its authenticity?

Leng Feng smiled slightly, this kid was obviously convinced that he was the Duke of Xi Guo, but he had to ask him questions, either he really wanted to know and wanted to get answers, and the other possibility was that he wanted to test himself and prove his cleverness.

Either way, this kid isn't as innocent as he looks!

"Just ask."

Putting away his smile, Leng Feng wanted to hear what questions he had to ask himself.

Di Renjie stretched out his first finger: "First, you should know the story of the two children arguing in "Liezi", do you know the answer?" ”

Leng Feng laughed: "I thought it was a problem, but it turned out to be this, I know the answer." The difference in the size of the sun is due to the different references, like a person who is neither fat nor skinny, he looks fat when he stands next to a thin person, and he looks thin when he stands next to a fat person. It's the same thing.

As for the difference between hot and cold, this is because of the different angles of illumination, and the temperature is also different depending on the time of day when the sun shines. Okay, you can ask the next question. ”

After Di Renjie thought for a while, he found that Leng Feng's answer was impeccable, so he quickly stretched out his second finger: "Then tell me, how fast is the speed of light?"

In Di Renjie's view, no matter what kind of light it is, it appears in an instant, and the answer to this question cannot be known to anyone.

Leng Feng smiled slightly, this question is tricky enough, but he just knows the answer.

"In the blink of an eye, it can run 30,000 steps, which is almost that step!"

After speaking, Leng Feng took a step of almost one meter on the ground in Di Renjie's stunned.
