Wang Qiankun is the host here and he was the one who invited them here.

So they had to give each other some face, so Lin Han and the other party tacitly agreed not to continue arguing.

But getting them to work together would be difficult.

They can't cooperate!

"Please follow me!"

Wang Qiankun led the way in front, the couple followed behind him, and Lin Han and the other two were at the back.

Wang Qiankun took them to the door of a basement. The two-meter-high iron door in front of them was very heavy. If it was solid, it would weigh at least five or six hundred kilograms.

With such an iron door protecting it, there must be good stuff hidden in the basement.

The man and woman also understood this truth, and there was a strange light flashing in their eyes, expectant and greedy.

Wang Qiankun took out an ancient iron key from his pocket. It was as long as Lin Han’s middle finger, and there were two protruding iron rods at the end, which were used to twist the mechanism.

It seems that this iron door has been in this place for a long time, otherwise this kind of key would not be needed to open it.

Because this key is obviously a very old key, it is easy for others to imitate it. At the same time, even if you don't have the key, you can easily open this lock.

At times like this, a door with better security measures can be used for protection.

Electronic password doors and explosion-proof doors are fine, they are much better than this iron door.

So if it is not impossible to move it, this kind of iron door will definitely not continue to be used.

In other words, the things hidden underneath should be of the kind that cannot be easily moved.

However, Wang Qiankun had said before that it was something his great-grandfather had obtained, so it was indeed quite old.

Or maybe the location where they discovered the treasure was here, so they established a stronghold here to guard the treasure.

From generation to generation, this place became their home.

This possibility is still very high.

"Buzz~" Wang Qiankun slowly pushed open the heavy iron door, but it was pitch dark inside.

Wang Qiankun pressed the switch on the wall with ease, and immediately the entire basement passage lit up.

There is a chandelier every three meters above the head, making it as bright as day inside, which is different from the darkness and gives people a sense of reliability and security.

Wang Qiankun didn't say anything and walked down the stairs.

Lin Han and others followed behind him, looking around.

The walls around were not made of bricks, but rather seemed to be carved out of huge stone walls. Even the stairs under your feet were carved out.

This made Lin Han feel that his previous guess was correct. This place should be the place indicated on the treasure map.

They couldn't move the treasure, and they didn't want to give it to others.

So we could only establish a base here.

The walls were made of stone and the basement had no sunlight, so it was extremely cold.

The air they exhaled turned white. Xiaoxiang and Liu Qinqin, who were wearing short-sleeved shirts, kept rubbing their arms with their hands and trying to clamp their legs together.

Lin Han also got goose bumps on his arms, but he put his hands in his pockets and followed the three people in front of him down to the basement.

After seeing what was in front of him, Lin Han knew why they couldn't move, because there was a stone wall in front of them, and a door was embedded in the stone wall.

If this door is not opened, the things inside cannot be moved out, and Wang Qiankun’s ancestors certainly did not do that.

"Why don't you pry the door open? With today's technology, it shouldn't be difficult, right?"

Xiaoxiang asked curiously.

It’s just an iron door. With current technology, we can break down any door, even into space. What’s so difficult about it?

"Naive!" Before Lin Han could answer, the woman couldn't help but snorted with disdain.

"In ancient times, in order to protect treasures, people would take some measures to prevent violent breaking into the door, such as setting up mechanisms inside or placing explosives.

If you break in violently, everything inside will be destroyed. And we are underground, and we might be buried alive.”

Yes, she was right. Everyone could think of and do the violent method of breaking the door. The person who set up the mechanism would be the first one to think of it.

Breaking the door by force won't work.

Otherwise there would be no need to invite them.

"Yes, that's right. That's why I asked you to come here today to crack this door. This is the treasure map. Maybe you can find some helpful information from it!"

Wang Qiankun took out the parchment with the map printed on it.

The man and woman's eyes lit up when they saw each other.

"Is this the treasure map that points to here?" the man asked excitedly.

But Lin Han and the others didn’t know why they were so excited. What was so powerful about this treasure map?

"Of course, I bought this treasure map as you requested. I hope you can use it!"

Wang Qiankun handed the treasure map to them without caring. When he saw Lin Han who was very confused, he explained:

"Here's the thing. This isn't the first time they've come here, but they said they needed some 'keys' to open this door. Of course, they were abstract keys."

"I know what that means." Lin Han nodded. The "key" he was talking about must be the treasure map.

They hoped to get some clues, but the person who could provide the clues was definitely no longer in this world, so they could only find the treasure map pointing to here.

Hoping there would be some information on it to open this iron door.

Lin Han didn't have the treasure map in his hand, and he had just had an unpleasant argument with the two men, so he didn't get closer. Instead, he walked to the iron door and checked if there was anything different on it.

There are many patterns and marks on the iron gate. Maybe they have some meaning, or maybe they are just decorations and have no other function.

However, what made Lin Han curious was that there were six small holes the size of keyholes in the center of the two doors.

The six holes were arranged in a circle, with the two doors separated by a crack in the middle and three holes on each side.

"Is this the keyhole?"

Lin Han heard Xiaoxiang's voice in his ears, and they followed him over. When they saw the small hole on top, they couldn't help but ask.

"It should be, but it takes six."

Lin Han nodded slightly. Such a small hole is most likely a keyhole, used to open the door, but six keys are indeed a bit too many.

What if I lose one? I don't know what the people who built this thing were thinking.

"What? Do you know something?" When Lin Han turned around, he saw Liu Qinqin staring at those small holes, as if she knew them.

So I couldn't help but ask.

"No, I just think it's very interesting." After hearing Lin Han's words, she quickly shook her head and retracted her gaze.
