Half a month ago, his subordinates had already found out that among the palace maids, eunuchs, grandmothers and others who were serving in Yonghe Palace, the most likely problem was Shi Lan.

This matter is very difficult to investigate, and Mu De and the others really took a lot of effort.

Shi Lan's mother's family looked like everything was normal on the surface, and when they investigated by conventional methods, they didn't find anything suspicious.

Until the fourth master gave the death order, even if a dog died in the family of these palace people, how and when it died, it had to be found out clearly.

Mu De and the others gradually discovered the unusual features of Shilan's mother's family.

Shilan's mother's family is an ordinary coat, and her life is not very hard, but she is not rich. A family of more than a dozen people was crammed into a small courtyard in the east of the city.

Even now, their family still looks like business as usual, except that the cooking time is a little longer than before every day.

In the past, everyone ate and drank about the same amount, but lately her family seems to have been cooking for a longer time than usual. I cook one or two more dishes than others every day.

This is what Mu De summed up after comparing the population and food situation of several families next to Shilan's mother's house.

And one of her native dogs died suddenly.

Ordinary people have dogs at home, and they are generally kept to take care of the home, and if they are not old or sick, they generally will not die suddenly.

The dog of the Shilan family died suddenly.

After sending someone to inquire, Mude learned that the smell of dog broth had wafted from his house.

Later, Mu De personally went out and quietly touched in the middle of the night, and finally found the clue.

There is a black dress and a pair of black boots hanging on the bamboo pole of her house, the material is extraordinary, and it looks like a person who practices martial arts.

After all, Mude, a martial arts practitioner, also wears such materials, which can be recognized at a glance.

The matter was finally clarified, and Shilan's mother's family was threatened.

And the person who threatened her mother's family lives in this courtyard at this moment. and have been living for at least a month and a half.

Because since a month and a half ago, he had already sent people to start keeping an eye on him, and during this time, there were no outsiders in Shilan's mother's house.

When did this person who threaten Shilan's family start staying here, Mu De didn't know, but this kind of threat method of living directly in someone's house and not leaving, he really saw it for the first time.

According to his observations, this man must be a master. It can be inferred from the wear and tear on the bottom of his boots.

In order not to startle the snake, and in order to think of countermeasures as soon as possible, Mu De went back to Baylor Mansion overnight to report to the fourth master.

Before failing to find out the identity of the other party, the fourth master chose to stand still.

Coincidentally, a few days after knowing that Shilan's family was threatened, Coincidentally, the stupid rabbit's body recovered.

The fourth master calculated in his heart, released the news that her body was safe, and then found a way to find out who the person behind Shi Lan was.

It's just that the people behind Shilan are too careful, and he has to find out the people behind Shilan without startling the snake.

If you want to start with the dead soldier who is in Shilan's mother's house, there is no possibility at all, so you can only start from Shilan's side in the palace.

The fourth master quickly made a decision, he wanted to shake Shilan a few shots solidly, so that she had to report to the master behind her, and if she had many times, she would naturally show her fox tail.

And the key to this few shots is naturally a stupid rabbit.
