When the last dot representing Han Xin of the Han army also fell, Li Zimu's side also fell a lot, and the two generals in Zhang Jingyang's hands also fell, which also had the reason why he was a step slower, after all, this was not Li Zimu's own operation, like the two dots representing Long and Zhong Liwu in his hand did not fall.

I only heard the sound of gears turning inside the metal door, and all the dots in front of Li Zimu fell down at the same time, and after a while, the heavy metal door slowly lifted up.

Li Zimu and Zhang Jingyang glanced at each other, and at the same time took a step back and leaned against the stone walls on both sides to prevent a hidden weapon from attacking, and did not forget to push the spirit to let her lean against the root of the wall on her side.

Before the latter could react, he was directly slammed by Li Zimu to the wall. Chi Ling's face turned red as he coincidentally rested his arm on her chest......

Seeing that Li Zimu kept looking at the situation inside the door, Chi Ling breathed a sigh of relief and did not speak, the latter did this for her good, although it was a little embarrassing to put this position, but it should be unintentional.

"Let's go" After waiting for the metal doors to shrink to the top, Li Zimu put down his arm and said without looking back, and slowly walked inside, Zhang Jingyang and Chi Ling followed him.

"Boom!" After the three of them just walked behind the door, the metal door that had been shrunk up suddenly slid down and closed, and several people hurriedly looked back, in case they were locked in like this, it would be too wrong......

"Fortunately, there is a switch that opens directly, I thought we were going to be locked inside" Chi Ling said with a sigh of relief, a switch is set up behind the door to open the door directly, which should be convenient for the people inside to go out, which is also understandable, after all, it is a secret room and not a tomb, specifically to prevent future generations from entering and setting up a dead mechanism.

"This ...... Is this a luminous pearl?" Zhang Jingyang said in shock as he looked at the glowing fluorite on the wall, and more than a dozen fist-sized luminous beads illuminated the originally dark secret room, and the entire space looked green and a little seeping.

"Well, it should be a luminous stone" Li Zimu approached a luminous stone and nodded and said, he knew what Zhang Jingyang was shocked, this thing is very rare, a natural luminous stone can be sold for tens of millions of Huaxia coins on the black market, which shows how rare and valuable it is.

In fact, luminous stone is not as mysterious and precious as people imagine, Huaxia is a big country that produces luminous stone, this thing is not rare in ancient times, but because of the passage of time, more and more digging leads to the end has been rarely seen, which is rare and precious.

This kind of ore will shine on its own after absorbing heat, a real natural luminous stone can keep a thousand years of the same dazzling light, and the imitation of fake luminous stone is a year or two before the flame, and the fake luminous stone is very harmful to the human body, long-term close contact will fall a lot of roots.

There is no doubt that the dozen or so in this secret room are true, because this is also two thousand years old, but it is still working, and the fake one does not have this effect, but Li Zimu is not very red-eyed, there are hundreds of this thing in his Swiss bank safe, which is much more than these, and after so many years, money is really not too important to him.

"Listen! there's like the sound of water!" said the Spirit, who hadn't paid attention to the luminous stone on the wall, but instead turned her attention to her surroundings.

Li Zimu listened carefully, there was indeed the sound of running water that the spirit said, he raised the flashlight in his hand and walked in the direction of the source of the sound, not far away.

"There is an undercurrent here, I said why is there no poisonous gas in the air" Li Zimu said with the corners of his mouth slightly raised, in this position under his feet in front of him, there is a gurgling stream, where the source is flowing and where it is going, you can only see this small section.

He didn't think it was strange to see this phenomenon, it was normal for there to be an undercurrent in the mountain, and some of the artesian wells on the mountain were dug by taking advantage of the continuous flowing water in the mountain, and this undercurrent should lead to the Wutang at the foot of the mountain.

"There's so much space in here, shouldn't it be a hollowing out of the entire mountain......" The spirit opened his mouth and exclaimed, the height of this secret room is seven or eight meters high, and there are rockeries and flowing water around it, which is the same as the park outside.

"There shouldn't be a hollow out, but there should be a lot of digging too" Li Zimu looked around and nodded, this is the middle part of the mountain, so there is a lot of room to dig. This should take a lot of time and manpower to build, and only people of Xiang Yu's level have this kind of appeal, and a lonely person like him Li Zimu is completely impossible......

"Let's go, go over first" Li Zimu shone the flashlight in front of him and said, although there are a lot of luminous stones inlaid in this cave, but it is completely impossible to see clearly, and you have to rely on the spotlight flashlight, at this time, the three of them built a stone bridge in front of them, and the undercurrent under the bridge is to wade through.

His right foot gently tested the stones on the bridge, but he didn't expect that after so many years, it was still very strong, so Li Zimu was relieved to step on the stone bridge with both feet, although it was okay to fall......

After crossing the stone bridge, there is a slender stone road winding forward, surrounded by artificially carved passages, and finally carved into the shape of tree branches, and there are pavilions and stone tables and stone benches next to it, where is this secret room, it is simply a large cave, and it is almost the same as a park, and there is no problem at all for the residents, of course, if they can withstand this darkness and loneliness.

"Look at this yellow thing, this can't be an iron mine, right?" Zhang Jingyang shone his flashlight behind the artificially carved tree, and saw that the whole piece of rock was not built artificially, but was pure and natural, concave and convex and yellowish-brown, which looked similar to soil.

Li Zimu approached and took a closer look, gently touched the stone with his hand, rubbed off a layer of yellow with black powder, put it on the side of his nose and smelled it gently, a little pungent, and there was a smell of sea salt, this is the original natural iron ore.

"That's right, this should have been an iron mine before, but it was dug up a lot by the people of the Xiang clan, and there is only a small part left here, and the taste is not very strong" Li Zimu nodded and said, I didn't expect this to be an iron mine, which is understandable, otherwise the Xiang clan spent so much energy digging such a big pit, which is obviously not worth it.
