"There seems to be some kind of mechanism hidden here." The clues that Yu Tong found were that a wooden barrel did not move at all, but one of the planks could move, which was not a normal situation at all.

Qiu Shaohu listened to what Yu Tong said, and after carefully checking it at the moment, and confirming that it was not a trap, he directly pulled the plank aside.

Throughout the cellar, there was a dull sound, like an elephant dragging its footsteps across the ground, bringing a heavy grinding sound.

After the sound of "creaking", a hole appeared in front of it again, and now it was extremely deep, and it was almost impossible to see the bottom at a glance along the old and dilapidated steps.

"It still doesn't taste good." Yu Tong sniffed carefully and said, "There must be something important hidden inside." ”

At this point, it is impossible to say that it is impossible to take a look.

One man and one dog, cautiously, took a step up the stairs and walked slowly down.

Although this staircase is old, it is very clean, the climate in the south of the Yangtze River is rainy, especially in tunnels like this, it is very easy to breed moss, but the whole staircase is very clean, obviously people often walk around here.

However, the slope here is very steep, and if you are not careful, you may fall.

"Are you alright?" Qiu Shaohu reminded him, after all, Yu Tong's body size is very small - the main reason is that his legs are not long enough, and it is easy to have an accident when he walks such a steep long ladder.

"You'd better mind yourself." After Yu Tong said this, he ran two more steps forward, and then he was silent.

Qiu Shaohu didn't mind, but after taking two more steps, he suddenly felt that something was wrong. It stands to reason that Yutong's side is too quiet, why is there no sound of walking?

As soon as he had this thought, Qiu Shaohu followed with a kick in the air, and then the whole person fell downward.

He immediately understood what was going on, and subconsciously wanted to shout, but he was afraid of being discovered by people outside, so he forcibly stopped screaming.

The whole staircase turned into a steep slope at some point, smooth as a mirror, and like a slide, Qiu Shaohu fell on it, and the whole body couldn't help himself, and he quickly rowed down to the bottom.

"Bang" and hear him fall to the bottom. It didn't hurt much, and it didn't hurt, but I was a little breathless.

In a sense, I was "secretly calculated", and because of a design that lacked virtue in this tunnel.

Looking back, you can see the clues. Except for the top few steps, most of the stairs are smooth slopes in the middle, and only the far right side is a little step for people to walk on. Guessing that it should be for the convenience of transportation, it is good to transport something down the slope directly, and the road next to it is used for walking.

Of course, this design saves a lot of effort to carry it, but the only problem is that it is easy for unfamiliar people to continue walking along the middle and then fall straight down like this.

"That's sinister intentions." Yu Tong said on the side, looking at her disgraced face, she obviously fell enough to save face.

"Oh, that's just right," Qiu Shaohu stood up and said, "There's another door here." ”

Qiu Shaohu and Yu Tong are both night eyes, even if they are in the dark, they can see everything.

The yellow-brown and blue-green eyes reflected a large iron door in front of him. It was poured whole from pig iron, and it was extremely strong and heavy, and when you hit it with your hand, it made a dull sound like an iron ingot, and you can imagine its terrible thickness. The cost of casting such a door and transporting it here and placing it under the tunnel, I am afraid that all the sheep and horses outside will not be enough to make up for this shortfall. It is conceivable that this entire ranch is probably a huge cover to cover up what is hidden behind this iron gate.

"I'm afraid I can't blow it up with explosives." Qiu Shaohu said.

"Is there really no way?" Rain Hitomi said.

"Not at all, unless," Qiu Shaohu looked at the complicated bracket in the middle of the gate and said, "I can find the key." ”

……

"Dad, you really have a way." Near the city gate, Cheng went to the warehouse first, and said to Cheng Tingdong: "In a few words, they really let us in." ”

"It's all human sophistication, you're still missing, you have to experience everything. Let me tell you, sometimes this aspect is much more important than martial arts. Cheng Tingdong was holding a cigarette pouch, a little proud.

The whole process was even simpler than the father and son expected, and now they were in front of the gate of the Sima family's warehouse, and what Sima Tingshen told them was right behind this gate.

"Oh no, Dad, they didn't give us the key!" Cheng Xiangxian saw that this gate was tightly locked, and said.

"Keys?" Cheng Tingdong frowned and took a closer look.

Suddenly, he understood something, and then took out the token he had asked for from Ru Ying, just in time to match the gap in the gate.

Using it as a key, the door clicked and slowly opened.

……

"No, no...... Not this, not this...... Is there really nothing else? ”

In the tunnel, Qiu Shaohu directly took down the compass and turned the things inside upside down.

Anyway, he looked for all sorts of things to see if he could help open the door.

But without exception, whether it is darts, crossbow arrows, or powder guns, it is impossible to hurt this gate in the slightest, let alone open it.

This made Qiu Shaohu quite frustrated.

"If it doesn't work, I'll call my people, and let's dig holes from somewhere else and see if we can dig into them." Yu Tong said to Qiu Shaohu.

"Forget it, you think it's just an iron gate? I'm afraid that in the entire secret room, there are steel interlayers of the same thickness on all sides, and needles can't be inserted or water splashed in, so how can a hole be dug in. ”

Qiu Shaohu said this, and saw the slender hilt. The broken knife was inside the box, hiding the light of the blade.

With the sharpness of the Beacon Dragon Knife, you can give it a try, maybe......

"Hey, what is this?" Qiu Shaohu only realized at this time that there was a strange thing in his large pile of luggage.

It looks boxy, angular and angular, and the whole body is made of pieces of wood intertwined and patchwork, and they are bitten together with similar mortise and tenon joints, which is extremely dense, and looks like a peculiar lock.

But Qiu Shaohu couldn't remember when he had seen him for a while.

Until he suddenly remembered that just a few days ago, in the Shengong Gate, he met the blind old monk.

"Open Lock...... Helps to open up all body and mind...... Don't be too closed......"

"Minghao's unlocking lock for me?" Qiu Shaohu thought about it at this time, a little surprised, and said in his heart: "The previous one was either an automatic wooden fish or an automatic Buddha bead, and this thing he made is really useful?" ”

Just as he was thinking like this, he suddenly noticed that the lock in his hand trembled slightly.

Originally, Qiu Shaohu noticed that although the whole lock is a mortise and tenon structure, it is extremely dense, and no matter where the splicing point can be found, that is to say, the whole lock is called "open" but it can't be opened at all.

However, at this time, there was a slight change, and from the outside tremor, a little crack appeared at the splicing point.

Then Qiu Shaohu moved lightly and found that the piece was opened by himself.

The second piece of spliced mortise and tenon was loosened along with it, and it was also easily removed. Then the third and fourth blocks ......

It wasn't until the end that he opened the entire lock that he could discover how amazing the interior of the entire lock was, and how meticulously carved it was to create such an ingenious thing.

however

"What's the use of that?" Qiu Shaohu reacted suddenly, and said helplessly: "Isn't this just a children's educational toy?" Do you think I'll be happy when I'm done? ”

"Hey, this door ......" On the side, there was a surprised voice from Yutong, "This lock, how ......?"

Qiu Shaohu looked back and found that he didn't know when, the frame of the iron gate in front of him had been opened, and the heavy door had cracked a gap.

"It's actually ...... like this" Qiu Shaohu looked at the open lock in his hand, and he was really surprised.

Yu Hitomi didn't know that he had so many thoughts, and at this time he couldn't help it, and squeezed in through the open gap, wanting to see what was inside.

"Huh, what are these?"

Her confused voice came from inside.

……

"Father, what is this?"

The door of the warehouse opened, and Cheng Fuxian looked at this group of piles of things, and was also a little stunned.

Everything in front of him was black, slender like hair, shriveled and like a tree branch, exuding a pungent smell more like medicinal herbs. No one has ever seen what the hell this is. Even if it's a guess, there's no clue.

"It's a bug, dried, but I don't know what breed." Cheng Tingdong was still well-informed, picked up a slender black "branch", and immediately made a judgment.

"What are you going to do when you find the dried corpses of so many bugs? The Sima family is reselling medicinal herbs? These made Cheng go to the first puzzled.

"Looks like things are getting a little in trouble." Cheng Tingdong said suddenly.

"Why?" Cheng Xiangxian still didn't understand.

"All medicinal herbs are either to cure diseases or to strengthen the body. Sima's family is wealthy, if someone in the family is really sick and needs rare medicinal materials, there is no need to hide it so much. There are so many medicinal materials, but it makes me think that when practicing martial arts, I always need various prescriptions as an aid in order to better improve my physique. ”

So, you mean ......" Cheng went to the first moment of enlightenment.

"I'm afraid these things are all Sima Yin's preparations for improving the realm! And it was also procured by the Sima family for her, which means that the Sima family not only knew everything about what she did, but even acquiesced and even supported it! ”

The courtyard building is as heavy as water.

……

"These are, Gu worms?"

The massive amount of sun-dried insect corpses in front of him made Qiu Shaohu extremely surprised.

It naturally recognized that these insects were those worm Gu, and if they were alive, they would be twelve points weird. After all, he had suffered from this in the resting place before. However, the insects in the resting place, and the ones in front of them, are still somewhat paradoxical.
