Sang Lan's father said annoyed: "Nonsense, I have never seen this thing before!"

Seeing Ji Yayun throwing my backpack beside the bed, I went over and picked it up and pulled out the wooden box containing a copper lock from it.

"What I gave you is a lock, not a ring key."

I smiled, opened the wooden box, took out the copper lock first, then flipped the wooden box, pinched the two ends of the wooden box with two fingers, and pressed it gently.

When I turned the wooden box back, I looked at it and it had changed.

The wooden box itself is not exquisite, and it even looks a bit old, but it has a red velvet lining inside. Judging from the size, it looks like it was tailor-made for copper locks.

With my action, when the wooden box was turned over again, the velvet on the side was still there, but the bottom turned into a wood color.

Not only that, there is an annular groove in the middle.

I took off the Ruyi ring and put it in, which happened to be stuck in the groove.

I repeated the action just now. Once when I flipped over the wooden box, the ring disappeared, and the inside of the box became what I saw first, with a velvet padding.

"There is a secret lattice in this box!" Sang Lan's father finally reacted.

I nodded, "I want to say that the original purpose of this box is to hold Ruyi rings. Placing copper locks on the surface, or other items of similar size, is just a concealment."

Sang Lan's father murmured: "The box was given to me by Han Sheng. What does he mean by handing me the copper lock and fingertips?"

I couldn't help but smile and said, "You're thinking too much. Although this copper lock is a bit old, it's not rare depending on the style. He gave it to you as a birthday gift from his father, but he wanted to buy it from you. Most of the time, he didn't know that this wooden box has something unique."

Seeing that Sang Lan's father was still suspicious, I simply told the details of Lin Fu and Professor Lin and the other three visiting the ancient house at night.

Finally, I said to Sang Lan’s father:

"When I heard the two professors tell this, I felt strange. Lin Fu was definitely not upright, but even if he was willing to steal and had a bit of a crooked talent, the process in this process was too seamless.

Not only did he succeed, except that he was almost beaten to death by Professor Gu when he saw something temporarily, but the two professors wanted to report him because of concern. How could ordinary thieves have such a scheming?

Now I finally understand that Lin Fu is probably a thief, the most despicable thief among the eight thieves! This Ruyi Ring, who is visiting the door, is the best proof!"

Ji Yayun couldn't help asking: "As you said, Ruyi's finger ring should be a thief stealing a family heirloom. Why didn't Lin Hansheng know that the finger ring is hidden in this box?"

I smiled: "There are a few thieves who steal things, except for a very special pathological mentality, and most of them are not for money. In a specific era, the wealth that Lin Fu stolen from the South Pearl was enough to turn him into a wealthy man. With money, how could he let his son become a thief again?"

Sang Lan's father nodded and suddenly frowned again:

"When you asked me for this copper lock, you already knew there was a ring hidden inside? You sneaked in at night to confirm that this ring can open the door of my house?"

As he said that, he became angry again: "Even if that's the case, what's your intention to run into my sister's house?!"

The "sister" he mentioned refers to Ji Yayun.

Through my previous contacts, I have seen that Sang Lan's father is indeed very good. After his ex-wife passed away, he only treated Ji Yayun as his own sister, which was nothing more than a single thought.

It is precisely because of this that he is resentful of my "rogue" behavior.

At this moment, I have figured out some joints because of the pictures that flashed in my mind.

Immediately said to him: "When I got this copper lock, I never knew there was a mechanism in the box. Now, I admit that I opened the door of your house with the Ruyi ring and the second door, and slipped into Ji Yayun's room. But... I only thought of the mechanism in the box after seeing this ring, and the whole thing was going on."

"Aren't you inconsistent about what you said?" Not only did Sang Lan's father look unhappy, but Ji Yayun and Dong Yaru also showed confusion.

I turned to Ji Yayun: "What happened after I fell asleep at the inn?"

Ji Yayun bit her lip, "I only remember that Lao He suddenly got angry and said that letting you fall asleep will kill you. Then, you really fell asleep. Then... and then the station disappeared suddenly. I returned to reality... What I said... do you understand, right?"

"I understand. Do you remember that someone walked towards me before I fell asleep?"

"Is it another you?" Ji Yayun widened her eyes, "Little Grass-headed Fairy?"

I nodded, "I really don't know what happened after that. I only know that I slept for a while and when I woke up, I was already holding you in your bed.

Until I just held Ruyi’s fingertip in my hand, some pictures suddenly appeared in my mind. That feeling was like a drunk person who was thinking back to some details one after another.”

Speaking of this, I handed the wooden box to Sang Lan's father and "take out the ring."

Sang Lan's father followed my gesture just now, pinched the ends of the wooden box with his fingers, and pressed it hard, but the wooden box did not respond.

He was definitely not stupid. After thinking about it for a moment, he immediately turned the wooden box back and pressed it again.

However, there was no change in the box.

I took the wooden box back, put the copper lock in, took it out, flipped the wooden box, pressed it, and then turned around, and the dark grid in the wooden box really appeared again.

"How could this happen?" Sang Lan's father was stunned.

I said: "A long time ago, the eight outer lines had a period of integration. Although they were separated, they had more or less mastered some of the skills of other companies between them.

This small box looks ordinary, but it is the design of the machine door. It includes at least a pin, a spring, a spring, a flip plate, four and even more mechanism designs.

Let’s putting a copper lock or something of similar volume and weight into it is the first step to turn on the mechanism; turning the box in reverse is the second step, pressing both ends is the third step.

But among them, there is another crucial and clever design. That is, there is a spacing for opening the mechanism. You can use the above steps to open the dark grid for the first time, but you have to be separated once in the middle, and then you can open the dark grid for the third time."

Before I could finish speaking, Sang Lan's father was already breathing continuously: "Who has such superb skills? If I ask me, the value of this box itself is much higher than that of this copper lock."

I said, "This is not the point. I am talking about this. I want to tell you that I used to be an ordinary poor student, but now I am an ordinary person. I don't understand these mechanisms. I really mastered the mechanism, discovered the secret of this box, and used the Ruyi Ring to sneak into your house, and there was someone else."

This time, before Sang Lan's father could tell me that I was contradictory, Ji Yayun blurted out: "It's the little grass-headed fairy!"

I nodded, "When the Shepherd Gu took away my consciousness and refined it into a small grass-headed immortal, in order to find the heavenly spirit and earth treasures for him. Although I don't know the specific process of refining, I can be sure that the small grass-headed immortal must have followed him to find many treasures.

Perhaps it was during that process that the little grass-headed immortal had seen similar mechanisms, and the little grass-headed immortal had a keen sense of the treasure itself. Together, it would be no surprise that the secret in the box was discovered."

I paused and flew my eyebrows at Ji Yayun:
Chapter completed!
