Just as Mu Cangnan's car was about to leave the hospital gate, Captain Liu arrived on his sidecar motorcycle.

Captain Liu hurriedly stopped Mu Cangnan to inquire about the situation.

Mu Cangnan briefly explained the situation to Captain Liu.

Captain Liu said, "I'll go with you! You know you shouldn't get involved in this, but if I go with you, it won't be considered a violation."

He understood Mu Cangnan's current feelings, but given Mu Cangnan's status, Mu Cangnan did not have the authority to hear this case.

Mu Cangnan nodded and told Captain Liu to get in the car so they could go to the driver's house together.

The driver lived in a large courtyard.

They went into the courtyard and found the driver's room.

There was only one small bungalow, with a large padlock hanging on the door.

Without a key, Mu Cangnan simply kicked the door open.

As the door was kicked open, a musty smell wafted out of the room, causing both Mu Cangnan and Captain Liu to frown and instinctively cover their noses with their hands.

Captain Liu and Mu Cangnan entered the room, which was really small, only about seven or eight square meters.

The room was crammed full of random things, and there were unfinished steamed buns on the table...

Mu Cangnan called his driver to help clear out the useless things from the room. Although the person said the letter was hidden in the cracks between the bricks under the bed, how could they believe everything that person said?

If you're looking, search the entire room thoroughly!

Captain Liu said, "Our comrades have already searched the house. There wasn't anything useful in it, but we didn't know he had hidden the letter in the cracks between the bricks."

Mu Cangnan said, "Let's take out all the useless things and search inch by inch. We're sure to find some important clues!"

The three of them cleared everything out of the room; the useless tables and empty boxes were thrown into the yard.

They opened the wardrobe and took out the tattered clothes inside, searching them one by one.

There was nothing useful in the cabinets and boxes; everything was cleared out into the yard.

Many neighbors gathered at the door to watch the spectacle, wondering what else could be found in this dilapidated house.

Captain Liu and Mu Cangnan checked the bed as well. There was nothing wrong with the bed. The large iron bed was also moved to the yard, and now the whole room was empty.

Mu Cangnan immediately noticed that the wall under the bed was bare, with exposed red bricks.

He used a screwdriver to pry the brick out and, sure enough, found a strip of paper wrapped in oilcloth hidden in the crack between the bricks.

His brow furrowed slightly; the words on the note were crooked and illegible.

Captain Liu said, "Something seems off about this character."

Mu Cangnan said, "Something is definitely not right. This writing should have been done with the left hand. This person didn't use their right hand to hide their handwriting."

Captain Liu said, "It's such a pity, it could have been a breakthrough point."

Mu Cangnan said, "There should be more things. If it was just to hide these things, there would be no need to pry off such a large piece of wall plaster."

As he spoke, he pried open the bricks next to him, and sure enough, he could pry open the other bricks as well, but there was nothing behind them.

Mu Cangnan pried open all the bricks he could, and to his surprise, after removing all the bricks, he dug out a small box from under the bricks.

He opened the box and found a telegraph machine inside!

Captain Liu slapped his thigh and said, "There's a telegraph machine! This person must be a spy, and a big one at that. He's been lying to us all along. The telegraph machine was hidden underground!"

Mu Cangnan said, "This person needs to be interrogated carefully! We must pry him open."

Captain Liu said, "I'll report the situation to the police station again and have them continue the interrogation! This person needs to be highlighted!"

Mu Cangnan said, "Give me a note, I'll take it back and compare the handwriting."

Captain Liu hesitated for a moment. This was against the rules; no matter how much evidence was found, it had to be handed over to the Public Security Bureau.

He paused for a few seconds and said, "You can take one. Finding Li Xiyue is the most important thing right now. I'll take the remaining three and hand them over to the Public Security Bureau."

Mu Cangnan said, "Thank you!"

Captain Liu said, "I'm also worried about Li Xiyue. I hope we can find her soon! Let's move all our things back and go!"

Mu Cangnan and Captain Liu moved all the belongings back into the room and locked the door.

Mu Cangnan instructed the driver to take Captain Liu back to the hospital first, and then let Captain Liu continue the interrogation.

After Mu Cangnan and his driver returned to the military region, he handed the small note to Chief Zhao and asked him to identify the handwriting on it.

When Chief Zhao learned what had happened, he slammed his hand on the table in anger, "If I find out who arrested Li Xiyue, I won't let him get away with it!"

But I've never seen myself in that picture before, and none of our comrades here write with their left hand.

Mu Cangnan said, "Indeed, no one writes with their left hand..."

His gaze sharpened. Since no one writes with their left hand, he would find a way to get some people to write with their left hand!

He instructed his phone to fetch a kettle of hot water and told his driver to spread the word on the way to the water room.

Just as he was telling Chief Zhao about their search, there was a knock on Chief Zhao's door!

Song Haoqiang's voice came from outside the door, "Reporting to the commander!"

Commander Zhao said, "Please come in!"

Song Haoqiang pushed open the door and walked in, holding a stack of documents in his hand. "Sir, there are some documents here that need your signature!"

Chief Zhao said with a smile, "Just put it there! I'm discussing the case with Xiao Mu right now!"

Mu Cangnan said, "Xiao Song, please sit down!"

He gave the driver a wink.

Mu Cangnan's driver picked up a thermos and made Song Haoqiang a cup of tea.

The driver walked over with the tea, but it seemed he stumbled and kicked his right heel with his left foot.

His hand wobbled, and a cup of tea accidentally spilled onto Song Haoqiang's hand.

Even if the hot water that has just been brought back is poured into a cup, it will definitely stay at a high temperature of over 95 degrees Celsius!

Song Haoqiang's hand immediately became red, swollen, and peeling. He immediately became angry, "What happened to you? How did you burn my hand!"

Mu Cangnan's driver immediately said, "I'm sorry, Comrade Song, I lost my balance. I'll write a report; I was wrong!"

Mu Cangnan said, "Old Song, I'm sorry, my driver drives me every day and didn't sleep well last night. I'll take you to the infirmary!"

He pulled Song Haoqiang towards the infirmary.

Song Haoqiang looked dissatisfied but couldn't say anything. He glared at the driver, thinking that the driver's job was done for!

As expected, Song Haoqiang's right hand was wrapped in thick bandages, and the doctor even told him that he could no longer use that hand...
