Xiang Liyu had mixed feelings at this moment.

After making peace with the imperial court, Xiang Liyu was appointed as the Minister of Education, in charge of the education of the Han Dynasty.

If he had been in the past, he would have been very happy to be able to promote Mohism's products in this position.

But it doesn't work now. Even he can't make a decision at will. The Minister of Academic Affairs does not mean that he can do whatever he wants.

What they develop must also be reviewed by the three provinces.

Of course, there are benefits. After all, in this position, although I can't obviously do too many things that benefit myself, I can still add some secrets.

Just don't go too far and don't touch the bottom line.

In the days that followed, Xiangliyu watched with his own eyes some craftsmen who originally belonged to the Mo family were divided up by the imperial court.

Although my heart hurts, there is nothing I can do.

At this moment, seeing the former disciple of the Mohist family walking into the main hall, Xiang Liyu felt a little confused, but it was just a weird feeling.

"Your Majesty, when the students were in Shu, they discovered a characteristic. Wherever crops grow well, there must be a mountain around it, and on this mountain, there must be certain grasses and crops.

It is difficult to survive if you go up there. Only within a certain distance around this mountain can the food production be the highest. However, the weeds here also grow very vigorously, so we need to constantly remove the weeds."

"The students also had exchanges with Yi Ji, and found that the situation in Jiangxia is similar, but one difference is that the area involved in Jiangxia will be larger, and there are no mountains around some places..." Liu Ji

Know your identity and your status.

Being able to ascend to the Great Han Palace is naturally not something you can do just to show off.

Someone had already told him the purpose of coming to him in advance, so there was no need to push him too much, just talk about the business when he came.

Hundreds of big guys are sitting here. Who has time to listen to your theory?

What everyone wants is results and some necessary processes.

Wang Buxuan frowned slightly.

If it is just the increase in grain production, it may also be a problem with grain types.

But the weeds are also growing quickly, which means it is not a problem of grain seeds.

It should be a problem of land, or to be precise, a problem of land fertility.

Because they have enough fertility and can provide so much nutrition, they all grow well.

As for the situation in Shu, there are also regional restrictions and the locality of some places.

This seems to prove another problem.

Things that don't grow well in places close to mountains should be because the surface soil is not thick enough and the soil fertility is too strong, so the crops cannot enjoy this kind of treatment.

Any further distance would probably be beyond the radiation range of this mountain, so the fertility of the land would not benefit them.

The best growth should be in a just right location with just the right thickness of surface soil to maintain a steady stream of fertility and at the same time, the crops can withstand it.

Therefore, this should be near a phosphate mine. Phosphate rock is originally one of the raw materials for making fertilizers. It is not unusual to have this situation.

But what is the situation over in Jiangxia?

Although there are no mines, there is still such a high output, and the radiation range is even wider.

Why does this sound like something is wrong?

Is it an underground phosphate mine?

It's not impossible, but the question is, if it is really an underground phosphate mine, how big should it be?

"How big is the area over Jiangxia?" Wang Buxu asked directly.

"There are several counties as big as this, but not all of them are like this. The students suspect it has something to do with water," Liu Ji said.

"Is it related to water?" Wang Buxuan was stunned for a moment.

"Yes, first of all, Yi Ji found during his visit that the high-yield areas of grain are all related to a river, that is, along both sides of the river. Anyone who draws water from this river will grow well. But at the same time, he also discovered a strange phenomenon. This

The water in the river is not drinkable. After people drink it, some strange symptoms will appear over time, such as headaches, inability to eat, general fatigue, and even yellowing of skin color, blood in urine, etc. "

"These situations have existed for a long time, and local people even spread the saying that drinking the water here will not cure them."

"It is said that there was a drought one year, and only this river still had some water. We couldn't bear to see all the crops die due to drought, resulting in no harvest."

"I thought that everyone would die anyway, so I might as well use the water here to irrigate. But later I found that after using it for farming, not only did the crops grow well, but people ate it without any problems, even the previous symptoms.

Already."

"By the way, one more thing, the water in that river has a bit of a smell, but it's not obvious. You can still smell it if you smell it carefully."

Liu Ji said blatantly.

But when we got here, Wang Buxian basically understood.

"Is there a certain time period where ghost fires are more likely to appear at night?" Wang Buxu asked with a smile.

"Yes...that's it. How did you know, Your Majesty?" Liu Ji was suddenly startled and froze.

Nowadays, human beings are still quite afraid of gods and ghosts, but as a scientist, Wang Buxu does not believe in these.

Of course, whether he believed it or not, he would not deliberately violate things like some idiots.

I don’t believe it, I don’t care, I don’t care, I just don’t touch you on purpose.

"I have seen relevant records in ancient books..." Wang Buxu blurted out.

Below, Xiao He, Chen Ping, Guan Ying and others couldn't help but look at each other. Which ancient book is the special one?

What exactly is recorded in this ancient book of yours?

Why is there such a mess?

Can you take it out for everyone to study?

In case there is something you missed, wouldn't it be great if we discovered it together?

However, Wang Buxu was too lazy to pay attention to this group of people, and directly educated them on science: "Ancient books say that the so-called will-o'-the-wisp is a place where corpses are buried, and the second is a place under the underground stone mountain."

"???" Many ministers scratched their heads and said, "Don't fool me. I don't have enough education. Why do you still say this?"

"Your Majesty, there are rumors among the people that will-o'-the-wisps will appear in this burial place. It is said that they often appeared in Changping in the early years, but they have rarely appeared in recent years." Xiao He said suddenly.

Wang Buxu smiled and said to himself that human beings have a lot of taboos. Otherwise, if they could grow food directly on the tombs, the fertility of the land would definitely be sufficient.

Of course, even if the king is not hungry, he cannot do this kind of sexual behavior. The most he can do is to put food on top of the animal's grave.

The principle is actually the same. Phosphorus will be produced during the decomposition of corpses, and phosphorus will spontaneously ignite when it escapes from the tomb and encounters air.

Therefore, the probability of a will-o'-the-wisp being generated in a pile of thousands of people is always higher than that in a solitary grave.

Similarly, sometimes, some phenomena cannot be observed.

For example, when visiting a grave, you pick up a stack of paper and bend down, and the paper immediately ignites on its own. This is an invisible "will-o'-the-wisp".
