The construction of Daming Palace was undertaken by Nanshan Construction Engineering, and Li Kuan was very familiar with the various structures in the palace.

The loud noise just now, others may not be able to tell what the sound is, but Li Kuan is very sure that it is the sound of an explosion.

There was an explosion in the Daming Palace?

Is this still worth it?

No matter what the situation is, the explosion in the Daming Palace alone is already a shocking event.

I wonder if there will be another bloody storm in Chang'an City.

In the Xuanzheng Palace, there was an eerie tranquility.

No one dares to express their opinions until the situation is clear.

If you say the wrong thing, the consequences can be very serious.

"Could it be that someone wants to do wrong?"

Fang Xuanling's face was worried.

For example, the conflict between Zi and King Wei today is becoming more and more obvious, and it is a bit like before the change of Xuanwumen.

Besides, he also knew that there was a gunpowder bureau under the Ministry of Industry, which specialized in black powder, and the power was very amazing.

This "boom" sound is very similar to the sound of black powder explosion I heard at the beginning.

The most important thing is that the sound comes from the harem, and the Xuanwu Gate of Daming Palace, like Daxing Palace, is in the direction of the harem.

"Whether it's the King of Wei or the Prince, no matter who did it, everyone will be greeted by a bloody storm."

The eldest grandson Wuji's face also kept changing.

In recent years, his attitude towards Li Chengqian has also been rather ambiguous.

In the past, he was a staunch supporter of Li Chengqian, but in the past few years, he has been leaving, and it is obvious that people can feel that the eldest grandson Wuji is not very optimistic about Li Chengqian.

"Your Majesty, Weichen has ordered the palace gate to be closed, and everything is fine at present, Danfeng Gate, Wangxian Gate, Jianfu Gate, and Yanzheng Gate are all fine."

Soon, Li Junxian's arrival broke the silence in the hall.

Li Shimin secretly breathed a sigh of relief.

Although he didn't quite believe that this explosion would have anything to do with Li Chengqian or Li Tai, he didn't have 10,000, so he was afraid of what happened.

Now that Li Junxian came over with Qianniuwei, and said that all the palace gates in front of him were under control, and there was no abnormal phenomenon, he could finally breathe a sigh of relief.

"Wait a little longer and see what news Li Zhong has there."

Li Shimin has been a golden iron horse for many years, and he still has this calming ability.

"Your Majesty, there was an explosion in the backyard of the Han Bing Hall in the harem, one palace maid was injured and one palace maid was killed."

Soon, Li Zhong returned.

"An explosion in the Ice Temple?"

Li Shimin frowned, and couldn't help but glance at Li Kuan.

The Ice Hall is the residence of Concubine De.

Speaking of Concubine De, everyone may not have any special feelings.

But when it comes to Yin, many people probably have some reactions.

As an important minister of the Sui Dynasty, Chang'an was the daughter of the Yin Shishi, and her father, the Yin Shishi, not only did his best to prevent Li Yuan from attacking Chang'an.

What's even more vicious is that the Yin Shishi also personally ordered the killing of Li Yuan's son Li Zhiyun, that is, Li Kuan's nominal father.

Not only that, but the Yin Shishi also asked people to dig up the ancestral graves of the Li family, and the methods were not vicious.

On the day of the destruction of Chang'an City, the Yin family was naturally raided, the men were killed, and the female dependents were thrown into the Yeting Palace. One eight

However, because of his good face, the Yin family was loved by Li Shimin, who was still the king of Qin at the time, and was able to escape the catastrophe.

Later, because she gave birth to the fifth son of the emperor, Li You, she was named Concubine De and became one of the four concubines in the palace.

Now that there was an explosion in the Hanbing Hall where she lived, Li Shimin couldn't help but look at Li Kuan more.

There are so many palaces in Daming Palace, why don't other palaces explode, but Hanliang Hall explodes?

"Your Majesty, it's true, the explosion destroyed nearly thirty percent of the buildings of the Ice Palace, but the reason for this explosion is very strange, that place seems to be an open space in the courtyard of the Ice Palace, and the explosion came from underground, making people confused about the situation for a while."

Li Zhong's pressure is still quite high.

Such a thing happened in Daming Palace, but he still didn't know what the cause of the incident was.

Because of the special situation, he also went to the explosion place of the Ice Temple, and he couldn't think of any other situation where the explosion would explode except for burying the explosive pack.

And as Concubine De's residence, there will be no idle people waiting to enter it, let alone burying explosives.

Besides, if someone really wants to make trouble, there is no need to spend a lot of trouble in the courtyard, and it will be detonated directly inside the Ice Palace, wouldn't the effect be better?

"Li Zhong, you said that the location of the explosion was in the courtyard of the Ice Palace?"

Li Shimin's meaningful eyes, Li Kuan saw it.

At this time, it is natural to stand up.

Don't say that you didn't think about dealing with Concubine De, even if you really wanted to make trouble, you wouldn't do such a low-level thing.

There are many ways to make Concubine De leave this world normally.

"That's right, I personally confirmed that there is a pit two feet wide in the backyard of the Ice Palace."

"Was that place a septic tank originally?"

"Septic tank?"

Li Zhong didn't react for a while, and he didn't realize what Li Kuan meant by the septic tank.

This thing was excavated when Nanshan Construction Engineering built Daming Palace, as for what role it is used for, because it is not a thing that can be put on the table, so there is no fanfare.

Therefore, everyone only knows that there are spacious and bright sanitary napkins in Daming Palace, and there is floor heating for heating in winter, but few people know the septic tank behind it.

"Yes, it's a place to collect and store the sewage that comes out of sanitary napkins."

As soon as Li Kuan explained this, Li Zhong understood in seconds.

He had also wondered where all the sewage in the bathroom had gone.

Will there be any pipeline leading to the outside of the Daming Palace, which will bring hidden dangers to the defense of the palace.

So the existence of septic tanks, he is aware.

It's just that he forgot the strange name after hearing it once, and only knew that there was a pool dedicated to storing sewage.

"Your Royal Highness the King of Chu, you say this, the place where the explosion occurred seems to be really a septic tank, although it was blown up in a mess, but some filth is still left at the scene."

Li Zhong thought for a moment and answered Li Kuan's question.

"His Royal Highness the King of Chu, the explosion of this Ice Palace, could it be related to the septic tank?"

Fang Xuanling asked on the side.

"That's right, although I haven't been to the scene to confirm, but nine times out of ten, the explosion has something to do with the septic tank. However, this septic tank will not explode in general, and there are special vents from the palace to each septic tank, unless the vents are blocked, and then there happens to be torches or other flames that are thrown into the septic tank, and the explosion will occur. ”

Li Kuan saw that everyone's eyes were focused on him, and quickly explained.

Otherwise, Li Shimin would have to worry that he would live in the Daming Palace, and whether he would be bombed inexplicably.

"So, this septic tank, it's dangerous?"

The eldest grandson Wuji frowned and looked at Li Kuan with an unkind expression.
