Lin Yu's expression couldn't help but change when he heard this, and he couldn't help but feel a little puzzled.

Li Zhensheng and others were also full of suspicion. They looked at the small box in Lin Yu's hand curiously. They were quite suspicious and felt that Yan Kun was a bit too boastful. Even if it was just an exaggeration, it was not exaggerated to this extent!

What can be packed into such a small box?

It is still worth thousands of troops. Even if it is filled with things that are as powerful as nuclear weapons, the damage is still limited!

"Senior, this is..."

Lin Yu asked hesitantly.

"You will know after you open it and see for yourself!"

The big bald man didn't explain much, and motioned to Lin Yu to open the box himself. The smile in his eyes was quite meaningful.

Lin Yu turned over and looked at the small box. He found that the small box was made of ebony and was exquisitely made. But what was surprising was that there was no gap to open the small box, and there were no cracks or cracks on the entire box.

Gaps can be used to open!

In other words, the entire box looks like a whole!

Lin Yu was a little surprised when he saw this, and couldn't help but look up at Yan Kun. Seeing Yan Kun's smile, he seemed to understand that Yan Kun was deliberately testing his feelings.

Li Zhensheng, Hu Qingfeng and others were also confused after seeing the wooden box clearly. They turned to Yan Kun and asked, "This box doesn't even have an opening position, how can you open it?!"

"If Mr. He can't even open this box, then he probably won't be qualified to ask for the contents in this box!"

Yan Kun held his head high and said with a smile.

Lin Yu couldn't help but shook his head and smiled. He looked at the wooden box carefully and found that there were no gaps or protrusions in the wooden box. It was impossible to open it.

"Sir, it's very easy to drive it, I'll do it!"

Bu Cheng said in a cold voice, then took out a dagger from his body, and then said to Li Zhensheng, "Old Li, go find me a hammer!"

Obviously, he wanted to pry open the wooden box directly.

Yan Kun was speechless for a moment, and hurriedly said to Lin Yu, "Boy He, let me tell you, if you smash or break it, you will destroy it, and this box has been circulated for hundreds of years. You really

Hope it is destroyed in your hands?!"

Although he had no right to control how Lin Yu opened the box, he did not want to see Bu Cheng open the box in such a rough way.

"How could I break such a beautifully crafted box?"

Lin Yu smiled and shook his head, waved his hand to Bu Cheng, and said, "Since this box can be opened, and there are no gaps or bulges on the surface, it means that it uses a very sophisticated mortise and tenon technique. It may require

It can only be opened with special techniques!"

Yan Kun smiled and said nothing when he heard this, and still looked at Lin Yu with a deep expression on his face. He had no intention of helping at all, and he did not judge whether what Lin Yu said was true or false.

Li Zhensheng and others looked at each other after hearing this. They all knew the mortise and tenon technique that Lin Yu mentioned. It was the main structural method of ancient wooden buildings, furniture and other equipment, because the protruding part is called a tenon and the recessed part is called a tenon.

, so it is called mortise and tenon structure.

The most superb thing about the mortise and tenon structure is that it can connect wooden structures without using nails.

Although the mortise and tenon structure is often used for mechanisms, the general mortise and tenon structure at least has places that can trigger the mechanism, such as concave seams or protrusions. However, the surroundings of this box look very smooth and solid, and there is nothing at all that can trigger the mechanism.

place, so there is no way to open it!

However, Lin Yu patiently took the box and sat on a chair nearby. He looked around the box carefully, then gently shook it next to his ear, and found that there was not much abnormal noise. It can be seen that the box

The space inside is not very big.

He held the box with his left palm, pressed the top of the box with his right palm, and then slowly applied force with both hands. He felt the changes inside the box, but he found that there was no loose sound inside the box at all. If he really used force, he might directly break it.
