No one knew what Yan Ruo and Xu Qingzhu said in the carriage, they only knew that after the carriage stopped, the relationship between the two people who came out of the carriage one after another seemed to be much better.

Even if Yan Ruo's body has the name of "grinding mirrors", most people do not doubt the relationship between them.

The son of a general, even if he is a dog, he doesn't dare to do anything to the princess, right?

After entering the palace, the two of them really didn't forget their business, and began to discuss the serial murder case in Kyoto.

The serial murder case was originally not a big case, and it would not have been possible for a royal daughter to investigate this matter. The problem is that those officials have been checking for a month or two without finding results.

And every once in a while, someone dies.

No one found the pattern, and the people were extremely worried, fearing that when it would suddenly be their turn to be killed.

At the feet of the Son of Heaven, of course, this matter is panicking, and it is impossible to ignore it.

In the end, the empress handed over the case to Xu Qingzhu, and she also valued him.

……

Although it is the first time for the two to work together, they also cooperate very well.

A smart mind with a mind of its own.

The other is to pay attention to details, consider and improve the problems that have not been considered, and then do a good job of cooperating.

This case, which had been circulating in Kyoto for almost two months, took only six days to solve the case with the cooperation of the two.

- The murderer was an inconspicuous young man, skilled in medicine and very intelligent.

The young man was down, ridiculed and abused, and his loved ones also lost their lives due to the cold treatment of others, and the seeds of hatred were planted in his heart.

Many years later, when the teenager returned from studying medicine, those people had long forgotten that they had bullied such a pitiful person, and they didn't notice anything unusual.

He used medicine and stratagems to kill the people who had ridiculed and bullied him one by one, and disguised himself as a pitiful little who didn't know anything.

Probably because his appearance is too loyal and honest, and his methods of committing crimes are very novel, no one has ever doubted him.

Yan Ruo and Xu Qingzhu also took a lot of effort to dig out this person.

As soon as the case was solved, the fame of Su Yingxuan and Xu Qingzhu soon spread throughout Kyoto.

Empress Dayue naturally named Xu Qingzhu as the crown princess - that is, the prince.

Once the prince is decided, he is generally not easily deposed.

As long as Xu Qingzhu doesn't make any obvious mistakes, after the empress dies, he will be the next emperor.

This news is not good news for Xu Qingzhu's competitors, and it is also not good news for the world's male protagonists.

Xu Huai'an is an ambitious person.

Even if he is a man, he wants to be an emperor.

For him, all the imperial sisters and imperial sisters are his enemies, and the most threatening of them are his third and fifth imperial sisters.

However, the third emperor sister is only a powerful mother, and she is not very smart, so she died not long ago.

Only the Five Emperor Sisters......

Xu Huai'an's eyes darkened slightly, the Fifth Emperor Sister has a cold personality and acts on her own, can such a person really be a good emperor?

In Xu Huai'an's view, the answer is no.

When it comes to governing the country for the people, Xu Huaian confidently believes that he will not be worse than anyone else.

The only pity is that he is not a daughter, and he can't compete for that position openly, let alone directly reveal his ambitions.

He had to do something now......
