No one is really not afraid of death.

It's just that some people can sacrifice their bodies for more reusable things.

But the more important thing here obviously doesn't include the use of the bathroom.

Some people here do not include the nobles in the palace.

Therefore, this problem of the eldest grandson Wuji is actually very vicious.

As long as it is true that the septic tank is dangerous, and Li Kuan has not said this before, then whether it is ill-intentioned or ulterior motives is not clear.

"Zhao Guogong, there are choking people to death when you eat, and there are choking people when you drink water, do you think there is any danger in eating and drinking water? There are also people walking on the street, walking and falling to their deaths, is it dangerous to walk? There are even more people who can't wake up when they sleep, isn't it better not to even sleep? ”

Li Kuan did not answer the question of the eldest grandson Wuji, but directly scolded back.

There are some questions that you answer yes or no, and none of them are good answers.

Rather than answering, it is better to leave the person asking the question speechless.

"Hmph, His Royal Highness the King of Chu, you are messing around! The harem of Daming Palace is the place where His Majesty lives in the dragon, how can such dangerous things as septic tanks be allowed? The most important thing is that you know that this septic tank is in danger of exploding, why have you never warned it? ”

It's no secret that the relationship between the eldest grandson Wuji and Li Kuan is not good.

However, seeing that the eldest grandson Wuji was so eager to deal with Li Kuan, Fang Xuanling couldn't help but shake his head.

This Zhao Guogong, such a wise person, why does he always make people feel that he has not played at a normal level when facing Li Kuan?

Could it be that there is something hidden between them that I don't know?

"Okay, let's solve the problem first, if this septic tank is actually likely to explode, then the danger must be eliminated before it happens. However, Kuan'er also said that the septic tanks in the Daming Palace have special vents, and they will not explode when they are idle, but why there was an explosion in the Hanbing Palace, this matter needs to be clarified. ”

While Li Shimin was talking, he glanced at Li Zhong, which naturally meant that he would arrange someone to find out more.

However, before Li Zhong could arrange manpower, new news came over.

"Concubine De wants to eat kebabs, so let the palace maid barbecue in the backyard?"

Li Shimin looked at the eunuch in front of him speechlessly.

"Your Majesty, it's true, the queen mother also went to the Hanbing Palace just now, and learned everything about the situation before the incident. The queen also knew that Her Majesty must be anxious to know the reason for the matter, so she arranged for the slave maid to come over and explain the situation, maybe it would be helpful to investigate this matter. ”

The little eunuch saw Li Shimin looking at him with questioning eyes, and he was terrified in his heart.

The eunuchs and maids who have been in the palace for a long time know that this kind of thing is the most dangerous when it comes to it.

Whether it is to extinguish the mouth or be implicated, there are often a bunch of unjust souls in the palace.

"Your Majesty, if this is the case, then this matter is probably explained. Weichen estimated that the explosion occurred because the carbon fire or other fire sources from the barbecue detonated the biogas in the septic tank.

In addition, Your Majesty, you can arrange for someone to check again, to see if someone has moved the soil above the septic tank behind the Ice Palace, or if you just barbecue above the septic tank, it will not cause an explosion. ”

Li Kuan also felt a little unlucky.

The explosion of the septic tank occurred occasionally in later generations.

However, on the whole, the probability of such a thing is very low.

I didn't expect to let myself touch it.

The most critical thing is that the location of the explosion is also very unfortunate is the harem of Daming Palace.

What's even more unfortunate is that the palace that exploded is still the residence of Concubine De.

It's a bit of a blur.

"His Royal Highness the King of Chu, since this septic tank is in danger of exploding, then solve it immediately, otherwise wouldn't you put Your Majesty in danger?"

The words of the eldest grandson Wuji were rarely recognized by everyone in the palace.

Except, of course, Li Kuan.

"Wuji's concern is also reasonable, Kuan'er, although this time it was an accident, everyone is worried about whether there will be another accident, don't make the palace restless because of this septic tank. In addition, if I remember correctly, your Chu Palace, as well as the Guanshishan Academy, and many nobles in Chang'an City also have this septic tank, right? ”

Li Shimin did not deliberately target Li Kuan.

Now, he knows very well that today's incident should really be an accident.

Li Kuan: This is a good intention, and he has done a bad thing.

"Your Majesty, to solve the problem of septic tank explosion, it is actually very simple. If you don't want to make any changes, just arrange for someone to regularly check that the septic tank vents are clear. If you want to actively consume the biogas in the septic tank, you need to make some appropriate changes. ”

Li Kuan said while thinking about the biogas digesters that were widely used in rural areas for a period of time in later generations.

Although the final popularity of this thing is not very high, after all, the initial investment is not low, and many farmers find it unacceptable.

However, the production and utilization of biogas digesters are not such a big problem.

"How do you actively consume the biogas in the digester?"

Li Shimin is also concerned about the explosion just now.

This kind of thing full of uncertainty is the last thing the emperor wants to see.

Especially the emperor, who has become accustomed to having everything in his own hands.

"The biogas produced in the septic tank can be burned. As long as the appropriate device is used to draw the biogas from the septic tank and burn it as fuel, it can turn waste into treasure, and at the same time reduce the consumption of honeycomb coal in the boiler room, and even make biogas lamps for lighting everywhere. ”

As soon as Li Kuan's words were finished, Fang Xuanling looked at him with admiration.

For so many years, what Fang Xuanling admires most about Li Kuan is that no matter what the situation is, he can always find a way, and he can always solve the troublesome things easily.

"Biogas lamps?"

Lighting is one of the big problems of our time.

Although the advent of whale oil candles has made this big problem not so difficult.

However, high-brightness and low-cost lighting are still a problem that plagues everyone.

Li Kuan suddenly came up with a "methane lamp", and Li Shimin couldn't help but be interested.

"That's right, the biogas can be burned, and if it is guided by the right device, a lamp can be lit."

Li Kuan never thought of making the complex structure of the biogas lamp in later generations.

He just wanted to build a simple biogas ignition device, so that this "biogas lamp" can be lit all year round, day and night, which not only solves the danger of biogas explosion in the septic tank, but also solves part of the lighting problem.

"You can talk about this matter specifically, if you can really turn waste into treasure, then today's explosion is not entirely a bad thing."

Although one palace maid died, one was injured.

But Li Shimin didn't care very much.

In these years, Li Kuan, an outlier, will attach so much importance to people's lives.

Other nobles, where do they care so much?

"Your Majesty, the situation is like this......"

Li Kuan saw that everyone was very interested, so he gave everyone a literacy literacy of the little knowledge related to the biogas digester and biogas lamp in his stomach.

After the mouth was dry, he finally eliminated this catastrophe from heaven.

This is really a person sitting at home, and woe comes from heaven.
