The passage is hundreds of meters long. Passing through the passage, Lu Ming finds a yard.

It turns out that the passage just now is just a side path. Here, it is the main courtyard.

Boom! Boom! ...

outside the courtyard, there are bursts of noise. It is obvious that outside the courtyard is the gate of the building. The master of Yuanluo hall and others are bombarding the gate.

They never expected that someone had entered the building ahead of time before they broke the array of opening the gate.

"I'm going to speed up!"

As soon as Lu Ming's figure flashed, he went toward the courtyard.

Inside the courtyard is a hall.

Lu Ming's eyes swept at once.

The hall is empty and there is nothing. Lu Ming is a little disappointed.

However, after the main hall, there is an inner hall. Lu Ming enters the inner hall.

The inner hall, a bit messy, has a huge platform.

Lu Ming carefully identified and recognized the platform, which should be used for weapon training. Around the corner, some materials were randomly piled up.

Bang bang bang bang!

The ball had already begun to eat, stretched out two tentacles, grasped the material and began to eat.

"This is star silver, black sky gold..."

as soon as Lu Ming glanced, he found two extremely precious materials for refining utensils.

Star Silver and black sky gold are all materials that can be used to refine medium-sized artifact. They are very precious.

"Wait!"

Lu Ming rushes over, grabs the star silver and the black sky gold in his hand and puts them away.

This is only what Lu Ming knows. There are many others that Lu Ming does not know. It is estimated that the level will not be low.

Lu Ming and ball, like the wind and the clouds, collected all these materials.

Bang bang bang bang!

The ball glares at Lu Ming, as if to say that Lu Ming robbed him of his rations.

"You guy, these materials are not cheap. I'll give you something else to eat!"

Lu Ming laughs.

The materials for refining medium-sized artifact are absolutely valuable.

However, apart from these materials, no other valuable things have been found.

Lu Ming speculates that this place should really be a strongman's cave. The strong man is refining tools here. Some of the useless materials are thrown on the corner of the wall, that is, the materials collected before Lu Ming.

However, what the strong man doesn't look up to is of great value to others.

Lu Mingxi Zizi looked at it for a while, and never found it again.

He left the inner hall and went back to the outer hall. He found a corridor on the side of the outer hall. Lu Ming walked along the corridor and came to the back. There was another yard. In front of the yard, there was a tall building, but the gate of the yard was closed. On the gate, there was also a large array.

Lu Ming tries, and finds that he can't get in at all and is blocked by the big array.

"It seems that another detour is needed."

Lu Ming pondered for a moment, then returned to the way he had come to the side of the channel, from the ball bit the gap, exit here.

"How do you close this gap?"

Lu Ming pondered.

Later, if Yuanluo hall masters break through the array, enter here and search, I'm afraid they will find this gap.

The ball seemed to see Lu Ming's idea. It opened its mouth and a black liquid gushed out, like a kind of black liquid metal.

Black liquid metal rushes into the gap and solidifies rapidly, blocking the gap completely.

"This..."

Lu Ming was a little confused and speculated that the black liquid metal was the impurity eaten by the ball?

Anyway, anyway, the gap is blocked, and Lu Ming is very happy.

Then the ball continued to refuel, nibbling at the old gold vein, and went to the inside of the building.

The ball began to bite the black wall again as the distance passed the gate.

A few days later, the ball bit through the wall, and Lu Ming enters through the gap. Sure enough, he finds himself in the building inside the gate.

Here, there is a secret room. Lu Ming begins to search.

At first, several secret rooms were empty.

It was not until we came to the largest Chamber of secrets that we found.

Around the secret room, there are several shelves, some jade bottles on the shelves.

"Shendan!"

Lu Ming's eyes lit up.

What has a great effect on the martial spirit realm is Shendan.

Here, there are some magic pills.

Lu Ming picks up a jade bottle and finds that there are runes on it. These runes are used to seal the jade bottle to prevent the loss of medicine.

However, it should have been many years since the seal's power had weakened, and Lu Mingyun soon broke the seal.

Then open the jade bottle, suddenly, a strong smell of medicine diffuse out."And it's effective!"

Lu Ming was overjoyed.

However, Lu Ming did not know what the magic pill in the jade bottle was called and what its effect was.

Lu Ming knew nothing about Shendan.

"No matter, put it away first, then go out and identify it slowly!"

With a wave of his hand, Lu Ming collected all the jade bottles. There were more than 50 jade bottles.

After putting it away, Lu Ming looks at the secret room.

In the middle of the chamber of secrets, there is a trace of dark color.

"This should be a alchemy chamber, and the trace in the center should be the place where the alchemy furnace is placed!"

Lu Ming speculated.

Although Lu Ming knows little about Shendan, he is also a master of alchemy in heaven. He is very familiar with the habitual steps of alchemy. If he looks at the layout of the secret room, he can speculate on many things.

Obviously, this is a alchemy chamber, but the owner left later and took away the furnace and most of the pills.

Perhaps, some pills which are not very important to the master of the cave were left behind, which was obtained by Lu Ming before.

But I'm afraid the owner of this cave is very important. The owner of the cave can't look up to him. Maybe Lu Ming can't.

Out of the secret room, Lu Ming searches again. Then, he finds a passage, but the channel also sets up an array. Lu Ming can't make it.

"This cave is really big. There are still some inside, so... Go on!"

Lu Ming is smiling.

This cave was obviously abandoned by its owner, and almost all the good things were taken away. But even if it is not important for the owner of the cave to leave it, it is also a treasure.

Lu Ming goes out from the gap where they came in again. The ball ball plays the same trick again, ejecting liquid metal to block the gap. Then they continue to dig and go to the deep of the cave.

After a while, the ball continues to bite a gap in the stone wall, and Lu Ming enters it.

This time, there was something special about the place they entered.

They seem to have entered a passageway, which is very large, with a diameter of at least 100 meters, and is surrounded by smooth walls.

In front of the passage, it's dark. I don't know where to go.

Lu Ming pondered for a moment and then walked along the passage.

Whoosh...

all of a sudden, there was a terrible roar in the channel, and then a strong attraction was generated in the channel, which sucked Lu Ming in the past.
