If those two women really had come to deliver food, then there should be dishes and chopsticks, or leftovers.

However, the house was only this big. He had walked around for a bit, but he hadn't found anything.

With her experience, Su Mu suddenly thought of a possibility. The two women had indeed left from here. If there was no food in this room, then it meant that there was a mechanism or some secret room.

Generally speaking, there was an unwritten trade secret within the Great Fu Empire. They would have a habit of putting mechanisms on the bookshelves for those who built secret chambers.

Hearing this, Su Mu looked towards the bookshelf. She slowly searched for a long time from the first shelf. When she reached the last shelf, she finally gave up. This meant that this bookshelf didn't have any mechanical buttons.

However, other than the bookshelves that could be used to design mechanisms, there were probably no other places that could do so.

Just as Su Mu was wondering, Zhuo Qingfeng suddenly shouted, "Su Mu, hurry and come here, Su Mu."

Su Mu looked towards the direction Zhuo Qingfeng shouted but found that Zhuo Qingfeng was standing in the middle of the floor and said, "Su Mu, do you feel that this floor is empty?"

Su Mu walked over and jumped for a bit. He used his hand to knock on the floor lightly. The sound of 'Tong, Tong, Tong' came out from the floor. It was as if there really was a hollow space down there!

Su Mu then said, "That's right, there is something wrong down there, but who would set up a secret room down there? It doesn't matter if the secret chamber is located at the bottom, but the key point is, where will the mechanism be located? "

"Where is the mechanism? "I can't possibly move this piece of floor up, right?" Zhuo Qingfeng muttered to himself.

Su Mu stood up and touched his forehead, beginning to recall if there were any related matters in the cases she had solved …

At that time, on the second day of her stay in Wu City, a similar thing had happened to a large family. At that time, a murder case had been committed in a secret chamber, but fortunately, Lin Yi had been more calm and collected than Su Mu.

Thinking up to here, Su Mu walked under the table. Then, he stretched out his hand and touched under the table. Sure enough, he touched a protruding spot.

She turned left towards that place, and a rumbling sound came over. There really was a mechanism.

However, Su Mu was pregnant and it was inconvenient for him to squat. Zhuo Qingfeng walked over and said to Su Mu, "I'll take care of my brain. Leave the matter to me. Don't worry."

Su Mu smiled at her in thanks.

Zhuo Qingfeng was focused on the loose floor, and after a while, the floor was completely cracked. Looking inside, there was something like a ladder placed below. Su Mu couldn't help but touch her lower abdomen.

However, there was only Zhuo Qingfeng here and it was not safe for Zhuo Qingfeng to go down alone. After taking a deep breath, Su Mu said, "Okay, let's go down together!"

Zhuo Qingfeng quickly stopped Su Mu and said helplessly, "Esteemed wangfei, you should naturally let me take the limelight. Your body is different now, you should stay here to rest first."

After Zhuo Qingfeng finished speaking, he winked at Su Mu. Seeing her playful look, Su Mu let out a sigh and said, "That's fine, but …"

Zhuo Qingfeng knew of Su Mu's worry as she was worried that she was alone. However, other than Zhuo Qingfeng, there was no one else that could rely on her and no one else …

Zhuo Qingfeng stood there with one hand supporting a depression in the floor above and one foot pointing downwards.

She only walked a few steps before shouting loudly. Then, with lightning speed, she climbed up and said to Su Mu, "No, I still don't dare go down. I heard something below …"

Su Mu patted Zhuo Qingfeng's shoulder to comfort him and then looked down. It was pitch black, Su Mu originally didn't agree to Zhuo Qingfeng taking the risk alone, but after going through all this, how could he agree?

Su Mu said, "Qingfeng, let's go down together. You go down first, I'll come down soon too. Don't worry, the child in my womb is very weird. He must be very sensible, he must know that his mother is doing something big."

However, right now, she was also at a loss and could only end up with Su Mu's thoughts. As Su Mu climbed down, it was as Zhuo Qingfeng had said, there should be something loud and powerful …

At this time, Zhuo Qingfeng was already down there, but Su Mu heard someone arguing from above the stairs, it seemed like the abbot had already entered. Su Mu thought, this was bad, it would be hard for her to get down from this position, and with the floor open, she would be caught red-handed, and at that time, she might not be able to kill everyone here.

If he could block the wooden board on top of it, he could also deal with the abbot for a while …

At this time, Zhuo Qingfeng found a mechanism button below and said to Su Mu, "Su Mu, be careful, I will close the floor soon!"

Zhuo Qingfeng exerted his strength and immediately heard the sound of the floor closing. The moment the floor closing, the abbot came in!

The abbot had just presided over the morning meeting, and was feeling extremely tired. When he saw the teacups on his table, he frowned and did not say anything. He just slept on the bed as usual, as if nothing had happened.

When Su Mu heard that there was no movement from above, she slowly climbed down. Just climbing down took her a lot of time.

Zhuo Qingfeng was naturally very worried and asked her quickly: "Su Mu, how is it, how is it?"

Su Mu smiled back at her, indicating that she was fine. The two of them walked side by side until they reached the passage to the secret room. They became more nervous, or perhaps it was because there were no torches …

Therefore, the two of them had no choice but to stay close to each other. After walking for a while, they finally found an opportunity. There was a torch stuck in the wall in front of them, and there were also flint stones placed at the side.

Zhuo Qingfeng quickly stepped forward and with a little strength in his hand, he opened the fire stone and placed it on the torch. The fire immediately lit up!
