Li Chong can only say this, and if he says it, he doesn't say it.

But......

After watching the song and dance performance, Li Chong did take Li Chengqian to visit the things he was interested in.

For example, in his fertilizer experiment, he heard that under ideal conditions, the yield of one mu of wheat could be increased from one stone to eight stones, which is a full eightfold increase.

Li Chengqian's whole person was also directly stunned.

Let's ask, in this world, there are still things that the teacher can't do.

"Can you really increase the yield of one acre of wheat to eight stones?"

Li Chong said: "That's just an ideal state, but, I estimate, at least three or four stones will definitely be no problem." ”

"Three or four stones, that's not a lot. Then teacher, why didn't you say it earlier? ”

"Not yet, one, the yield of this fertilizer is too low, take it to plant a few acres, more than a dozen acres, it may be okay, but if you want all the people of Datang to be able to use it, at present, it can't be done."

"Also...... Whether the crops with chemical fertilizers can be eaten or not, and whether they will be poisoned after eating, this cannot be known after a period of experimentation. ”

"Uh...... So what kind of tests will be conducted? ”

Li Chengqian asked.

"For example, human trials are specially given to some people who don't want to die, to see if there will be anything wrong with eating."

"Uh...... Have you found such a person, teacher? ”

Li Chong said: "Didn't you see it just now." ”

“？”

Li Chong: "It's those five Japanese girls." ”

“……”

Li Chengqian understood.

"That'...... Teacher, don't you want a man to do the test? ”

Li Chengqian asked again.

"Because I don't like men."

“……”

All right!

Li Chengqian understood.

"That means that you don't really want those girls from the Japanese country, teacher."

Li Chong raised his head and said, "You can't say that!" After all, you know your teacher my dreams, if I am invincible...... Ahem! ”

"In other words, it's okay to do the test and whatever."

Li Chengqian said.

"You know me."

……

When it comes to this year......

Since the sucrose of Tianzhu was also transported to Luoyang in large quantities, Li Chong naturally tried to add these sugars to the black powder.

Although, this is not an authentic white sugar.

But......

If you use the naked eye to distinguish it, it still feels like the black powder has some more power.

Of course!

He still needs to continue to study and study this problem of proportion.

gave Li Chengqian a brief sentence that this sugar is a strategic material, and then Li Chong devoted himself to the research of how to produce white sugar.

In the evening, a large pot of braised pork was stewed.

When the five Japanese girls smelled the fragrance, their saliva almost flowed out.

After all......

They had never seen anything so fragrant.

Li Chengqian also stayed in the princess's mansion and went back after dinner.

In the end, Li Chengqian looked at the Japanese girls.

All I can say is......

This can be regarded as the luck of these Japanese girls.

After all......

It was his teacher who met him.

……

Seeing that his teacher also had something he was interested in, Li Chengqian did not continue to bother.

And Li Chong's side......

After Li Chengqian left, he thought about it, and let one of the Japanese girls wash his name and then go to bed.

……

Liaodong.

In the fourteenth year of Yuan Heng, August.

The fleet has been exploring the east for two months, and still has not seen the legendary New World.

This time they went to sea, it can only be said that it was a little dangerous, because they encountered a certain degree of bad weather.

On this sea, to be honest, there are still some dangers at times.

Of course!

Fortunately, this time, they narrowly avoided it.

At last......

Their ship was probably eighty percent damaged, and then they returned to port.

Li Zhi told Li Chong all these navigation data.

Li Chong felt ......

This must be related to what the sub-height is, if you can cleverly design a safe route, then the safety of future navigation may be more guaranteed.

Of course!

This requires a lot of nautical data to support it.

Li Zhong asked Li Zhi to pay attention to this.

And Li Tai's side, this year, also sent Li Xin to Luoyang to pay tribute.

Of course, while paying tribute, he must also discuss things with Li Chengqian.

After the discussion was over, Li Xin found Li Chong.

Because......

His father seemed to be going to send him to Australia to develop Australia, and Australia seemed to be the only place that Li Zhong knew more clearly.

"Your father sent someone to Australia?"

Li Xin also said uprightly: "If you are talking about those kangaroos, indeed, we have found it." ”

Li Chong said: "Then your father is really hidden." So...... What do you want to ask? ”

Li Xin said: "I want to ask, how is the situation over there, if nothing else, my father should want me to go there to build a country." ”

Li Chong also said: "Actually, I don't know much about that place, but ...... That place is a good place. ”

"In addition to the fact that the wildfires may be more frequent, it is very good to raise cattle and sheep, as well as to develop large-scale mechanized agriculture."

"The only downside is ...... The place may be far away, and even if there are cattle and sheep, it may not be possible to transport the goods out. ”

"The cost of this transportation may be a bit high."

"That's right! There's hardly any population over there, so ...... This is actually a big disadvantage. ”

Li Xin wanted to say something in the end, but ...... He still didn't say it after all, after all, Li Chong couldn't manage that far.

It depends!

If he didn't say well, he would raise troops when he returned, and then turn against his father.

Over the years, Li Tai's health has also begun to be a little worse.

No way!

He is too obese, and maybe he has a little high blood pressure and hyperlipidemia by now, but fortunately, he should not have noticed the symptoms of wind disease yet.

It's Li Zhi's side......

Li Chong has never heard whether Li Zhi has suffered from wind disease.

All I can say is......

Be careful.

Li Zhi is also forty-eight years old this year, and Li Zhong estimates that according to his age, it is very likely that he will have symptoms of wind disease in the next few years.

Of course!

It depends on his usual eating habits or something, as well as rest or something, whether he is healthy or unhealthy.

"Be reasonable!"

"It's almost time."

After sending Li Xin away, Li Chong said to himself.

It's still Li Xiang's good!

A proper crown prince.

No one will fight him next.

Now he just waited for his father to die, and then succeeded to the throne smoothly.

Unlike this Li Tai and Li Zhi, this son has given birth to a lot.

And......

Sometimes, this disease is probably related to my son.

After all......

A lot of the time, I was angry with my own son.
