The entire Han Mansion covers an area of about 100 acres, which of course cannot be compared with the mansions of the city lords and big families outside. However, the resources of the Overwatch Valley are scarce, and the land is not much, so the scale is still quite large.

Under Wang Meng's guidance, Chen Hao learned to use his divine thoughts to guide the aura to explore along the ruins.

"The focus is still on the original study, bedroom and the like, and most of the entrances to the secret rooms will be arranged in this kind of place. Wang Meng reminded.

After exploring for a while, Chen Hao arrived at the inner courtyard of the original Han Mansion, which was originally a garden. When he searched the rockery in the garden with his divine thoughts, he unexpectedly found that his divine thoughts were cut off.

Although this is more unexplored, this is a doubt in itself. So Chen Hao called Wang Meng, and after Wang Meng explored, he said, "Most of them are here!"

He called the Zhuang Ding he had brought with him and asked them to dig up the collapsed rockery, and sure enough, they found something strange.

Under the rockery, where it should have been dirt, there was a layer of flat stone slabs that were not gold or jade, and at a glance it was clear that it would not be a natural occurrence.

"There's a formation ban here. Wang Meng said.

The villagers dug along the stone slabs until they found a trace of a seam, and Wang Meng told them to stop.

This layer of slate didn't look very strong, but Chen Hao took an iron pickaxe and smashed it hard, but there was no crisp sound of iron and stone intersecting, as if it had smashed on some kind of tough and thick material.

"That's the effect of prohibition, it's not so easy to break by violence. Unless the force applied exceeds the upper limit of the forbidden formation, even then, the contents may be destroyed. Wang Meng said to Chen Hao.

Then he began to deduce calculations, preparing to use technology to break the ban.

As a formation expert, the prohibition that Han Sui was able to make in the Overwatch Valley was difficult for him!

He was going around and using various materials to form a larger formation, and then connected them with aura. This formation began to operate, and Chen Hao could see the endless flow of aura, which was withdrawn from the formation arranged by Wang Mengxin, and then dissipated outside.

After about an hour, Wang Meng happily said, "It's done!"

He took the shovel in Zhuang Ding's hand and pried it at the seam of the stone slab, and the stone slab loosened, which proved that the prohibition was no longer in effect.

The Zhuang Ding quickly pried a large hole in the stone slab. Sunlight streams through the hole, and you can see that the illuminated section appears to be a square passage, and the four walls are made of the same kind of stone that has been pried open.

Wang Meng took the lead and jumped down, if there was any mechanism, he would have much more experience in dealing with it than Chen Hao.

Chen Hao also followed Wang Meng from the passage to the end. The farther away from the hole, the darker it became, and Chen Hao casually cast a lighting technique.

This secret room does not seem to be of a large scale, and the two of them walked out of less than ten zhang before they encountered a door.

Strangely, the door was not locked, and there were no mechanisms attached to it. Wang Meng pushed it casually, and the door opened.

It seems that the original prohibition is the only protection in this secret room. After all, this secret room is in the City Lord's Mansion, and it is itself under protection, and it is enough to have a prohibition to prevent unsuspecting people in the palace from discovering it.

In the soft light of the illumination, the scene in the chamber was unobstructed.

I saw that this secret room was about three zhang square, and there was a table and a chair in it, as well as a large bookcase. In addition, there is a stone platform on which several books and materials are randomly placed, and next to it is a furnace for refining tools.

There was an incense burner on the table, and some paper on which I had written. The door of the bookcase was also open, and there were a lot of books inside, as well as a few jade slips.

"This is where Han Sui studied refining weapons?" Wang Meng said suspiciously.

Chen Hao looked forward, and on the other side of the entrance, there was a small door. He took two steps forward and pushed open the small door, which contained a room that was smaller than the outside.

There was a bed in the room, but nothing else, and it looked like a bedroom.

The only thing that was more special was that the four sides of the hut were arranged with things that looked like formation components, made of some metal and jade, and inlaid with gems and spirit stones. Chen Hao glanced at it and found that there were a total of sixteen identical devices, which were extremely evenly distributed. But at this point these things are not activated, and it is impossible to see what they are for.

The two of them were careful not to touch anything, so as not to inadvertently destroy the message that these objects could convey, and carefully observed and recorded the layout of the room one by one.

"This is not Han Sui's secret room for refining, it should be Han Mo's residence. Wang Meng said.

He carefully observed the sixteen identical devices in the hut and said, "This is to keep out the evil spirit...... Ritual weapons, but they can't be considered ritual weapons, but they are just a bit like ritual weapons, and they seem to have some connection between them. ”

Chen Hao walked to the table and looked at the paper on which he had been written.

The handwriting on the paper is flying and dancing, but the end of each stroke is a little stiff and abrupt, as if because the size of the paper is not enough, so every word is still unfinished, and the size is forcibly limited, which looks like people have an indescribable sense of grievance.

"This is a note on refining magic weapons. Chen Hao carefully looked at the contents of the first piece of paper and found that it recorded refining materials such as cloud mud stone and gas gathering sand, and also marked the size, size, weight and other parameters.

He reached for the first piece of paper, flipped through a few more sheets, and sure enough, it was a note on the refining weapon.

There was a drawing of the Spirit Gathering Array on the paper below, but Chen Hao had never seen the other magic circles connected around it. But just by relying on the Spirit Gathering Array, I knew that this must be a blueprint for refining weapons.

After flipping through the papers one by one, Chen Hao said with some surprise: "Han Sui is indeed imitating the iron wall bricks, but he didn't do it himself. It should be his grandfather Han Mo who did this!"

Then the matter is already clear, this is the hiding place of Han Sui's grandfather Han Mo for so many years.

It may seem that the defense is not tight enough, but this secret chamber is located in the city lord's mansion. If it weren't for the sudden accident of the Ding family, who would dare to offend the city lord who was high up on weekdays? Who would be able to search this mansion at will?

"I didn't expect Han Mo to have some unique features in refining weapons. After Chen Hao finished reading those few pieces of paper, he suddenly felt that Han Mo's level was much higher than his own.

He had also tried to study the damaged brick in his hand, trying to see if he could make it himself. But after collecting a lot of materials from the White Horse Cave, he felt that it was impossible to complete this task.

However, judging from the notes left on the table, although Han Mo is also an imitation of iron wall bricks, he is almost successful!
