Li Yichen carefully closed the last door, making sure that no details were missed, then took a deep breath and slipped into the space.

I checked on the two unconscious people first. They were still asleep. Grandpa Wu and I carried them out of the room and placed them in the place where they had fainted. They should wake up in three or four hours from the injections they had received. It had already been an hour and a half.

Before leaving, he restored the door to the way it was when Li Yichen first came in. After everything was ok, he entered the space and said loudly: "Suihe, it's done." Suihe, who was driving, heard it and knew that Li Yichen had succeeded. He stopped hesitating and stepped on the accelerator to drive back quickly.

When Li Yichen entered the space and went to the small kitchen to get the roasted lamb, he met Grandpa Li who had been waiting there for a long time. Seeing Li Yichen's expression, he knew that this trip would be fruitful.

Old Master Li happily pulled them out of the space and lit a fire in the yard to heat up the whole lamb. He expected Suihe to arrive soon. Li Yichen went inside and changed his clothes, creating the impression of having been home all day. Indeed, who would have thought that they could travel over a hundred miles in such a short time? This plan was truly brilliant.

The three of them sat around the fire, and Li Yichen was whispering to Old Man Li. Old Man Li was quite surprised by what he had found in Mian Liu's room. "Besides the obvious cash and gold bars, the most important thing is that we found the account books, and we've copied them all. Many of Mian Liu's men are drug addicts, which is a clue. One of his former subordinates must have come with him. If we follow this line of inquiry, we'll definitely find a clue."

“Have you seen the account book?”

"I've seen it, and there's only the name of the person. I don't know which province they're from or what they do, but this is still a big improvement. I'll finish dealing with it tonight and then figure out how to understand the account book."

"The information says that Mian Liu doesn't have a high level of education, so this account book certainly isn't too complicated. First, you should summarize the account books and see if we can find any clues."

"Okay, Grandpa, with this evidence, we have enough leverage to catch them all in one fell swoop."

After a while, Suihe arrived by car. They were all drunk again today. After a busy night, Suihe and Li Yichen used the excuse of being too drunk to drive to successfully keep them and get some information. They only sent Mian Liu's three men back on the third day.

Then they did not go back, but went directly to the garrison troops in Tibet. The troops sent by Yuan Zhengjian to assist will arrive in the next few days, so they need to contact the garrison troops in advance, otherwise there will be problems if the timing is not right.

Li Yichen did not hand over the evidence. Not to mention the garrison troops in the same province as the Cotton Six den who were completely unaware of it, even his old superior Yuan Zhengjian did not believe it.

Why didn't he believe it? Because Yuan Zhengjian's name was on the account book, and the money he'd been collecting began fourteen years ago, when nineteen-year-old Li Yichen had just been transferred to the border for defense. Unexpectedly, Yuan Zhengjian had already been acting as a protective umbrella for Mian Liu. Suihe shared Li Yichen's sentiments: he didn't believe anyone.

Last night I looked at the names on the account book, but there were actually few people I recognized. However, because there were too many names, some of the amounts were huge, and some were relatively small, I couldn't figure out what was going on.

The account book is probably over a decade old, and the dates show that it's still occasionally recorded. When Suihe and Li Yichen assassinated Mian Liu, they didn't instruct them to take anything from him, so this account book must have been taken by Mian Liu after he escaped, otherwise it wouldn't be there after over a decade.
