Although Su Cheng had no evidence, Su Cheng's actions since entering Chang'an have already proved his ability. Since he could make Su Cheng treat him seriously, he is somewhat sure.

For a time, Princess Changle was in a mess. The position of crown prince was still stable. Although the King of Wei also wanted to compete for the crown prince, she always felt that the possibility of her father being easy to be crowned was not high.

Moreover, even if the father and emperor are easy to crown, the crown prince was demoted to the king, at least he would not have any worries about his life.

The nature of rebellion is completely different.

The situation in the court today is not as strong as before.

Princess Changle grabbed Su Cheng's hand vigorously and said in a panic: "Should I remind my father? Or persuade the prince to do my best?"

Su Cheng explained calmly: "If the prince really intends to rebel but does not tell His Majesty, it is a deception. But if you want to remind Your Majesty, we have no evidence. Your Majesty will think that I am sow discord, and may even suspect that I have stood on the side of the King of Wei."

Princess Changle was just panicked at first, but now she calmed down and figured it out. She really can't act rashly in this kind of thing.

The question facing Princess Changle now is, choose father or prince brother?

Or this is not a choice for Princess Changle, of course it is to choose the father!

For her, the father was closer, and for Su Cheng, the same was true.

After all, it was a princess who grew up next to Li Shimin and Empress Changsun. Princess Changle quickly calmed down and analyzed: "If the prince's brother wants to rebel, it is impossible for him to have no clues. As long as you investigate, you will definitely find evidence."

"But the husband is not easy to get involved. After all, the father will inevitably feel a grudge in his heart when he investigates this matter for no reason. Therefore, it is better to tell the fourth brother that the matter is not revealed. The fourth brother will definitely investigate it to the end!"

I have to say that Princess Changle's plan is really good. She picked herself out and let Li Tai charge in a hurry.

Su Cheng pondered: "The firearm surveillance lost a batch of gunpowder, and I have sent someone to investigate."

Princess Changle heard this and said quickly: "Mr. Langjun went on the battle with him. The responsibility for losing the gunpowder in the firearm surveillance is not on Langjun!"

After saying that, Princess Changle reacted and said in a lost voice: "My husband suspects that the prince sent someone to steal the gunpowder?"

Su Cheng whispered: "It's because of this suspicion that gunpowder is useless. Who would steal gunpowder from a warehouse? Who could make the firearm prisoners take a big risk?"

After hearing Su Cheng's analysis, Princess Changle also felt that Su Cheng's suspicion was not unreasonable.

"Then you really have to check it carefully. The power of gunpowder is so powerful that it is really dangerous to spread it!" Princess Changle said worriedly.

If it was just a mutiny, she was not worried. After all, her father and emperor were very talented and would not be able to deal with a mere mutiny.

But it is hard to say if you use gunpowder. Even the majestic cities of Goguryeo were easily destroyed by firearms.

Su Cheng was not worried much. If he was using gunpowder, he could overturn the entire palace. However, when Li Chengqian used gunpowder, it was not that Su Cheng looked down on Li Chengqian, but Li Chengqian would be good if he could set off fireworks.

Su Cheng hugged Princess Changle in his arms and comforted him: "It's just a guess now. Even if the prince really rebels, it will not cause any storm. Today is different from the past. The prince and His Majesty are several different from Li Jiancheng back then! So, don't worry, I didn't tell you at the beginning, just because I was afraid that you would worry."

Princess Changle nodded slightly. She felt very relieved lying in Su Cheng's warm arms.

But when she thought of the prince's rebellion, she still felt sad, after all, it was her biological brother.

And she really couldn't imagine how sad her father and mother would know, especially her mother.

Thinking of this, Princess Changle felt so uncomfortable that she said quietly: "I really hope that the husband's guess is wrong. I hope that the prince's brother can wake up, otherwise how sad the mother would be."

Su Cheng couldn't help but be silent after hearing this. If Li Chengqian rebelled, the hardest thing to do was Queen Changsun, one of his husband and one of his son.

"Don't show any strange things in front of His Majesty and the Queen!" Su Cheng reminded.

Princess Changle nodded and said, "I naturally know that the husband should also pay attention to it. Whether the gunpowder is lost to the prince or not, it is ultimately a great danger."

Su Cheng patted her smooth and delicate pink back and comforted her: "Don't worry, go to bed quickly!"

In the following time, Su Cheng still had social engagements, and the entire Chang'an officials and people were still immersed in the excitement of destroying Goguryeo, so the banquet was particularly refreshing.

However, Su Cheng's mind was all focused on investigating theft of gunpowder. What made Su Cheng relieved was that Zhang Chunning finally checked and confirmed that neither the musket nor the cannon had been circulated.

Then what did Li Chengqian do when he got gunpowder?

Buried under the palace?

Not to mention whether Li Chengqian has the brain to think of blasting. The palace is so big, where can Li Chengqian be buried?

It’s useless to bury somewhere else, but how can you bury your Highness Liangyi without knowing it?

Over the past year, Empress Changsun has been in the palace?

Unless Empress Changsun supports Li Chengqian's mutiny, how is this possible?

Then Li Chengqian could only secretly build muskets or cannons, but it was so easy to build muskets or cannons.

Although it happened last year, as long as you check it carefully, you can always find some clues.

Starting from Zhang Chunning's investigation, Su Cheng was still a little relieved that all the firearms prison officials were removed from the list of suspicions. After all, all these people were promoted by Su Cheng.

The supervisor, chief clerk, left school, right school, lieutenant colonel, Zhen official, etc., had no problems. Su Cheng was relieved and doubted whether he was too suspicious.

If you look further down, you will be the supervisory work, but the supervisory work is not even at the level. Can Li Chengqian be attracted to it?

Su Cheng finally decided to investigate. Although the supervision work was not included in the product, it also had real power in the firearm supervision and was involved in the warehouse.

This is something that Su Cheng is very sure about Li Cheng!

Could it be that Li Chengqian has not planned to rebel yet?

Could that batch of gunpowder really gets damp?

Just when Su Cheng was wondering if he was too suspicious, Chen Shan ran over excitedly.

"Master, I found it!" Chen Shan said excitedly.

When Su Cheng heard this news, he felt relieved. It was not pleasant to guard against thieves for thousands of days. Even though he knew that Li Chengqian would rebel, he still hoped to finish the matter soon. As the saying goes, die early and get reborn soon.
