Looking at the girls who were still busy in the distance, Lu Yu began to scan carefully around the waterhole, looking for the entrance of this underground building, through careful scanning, Lu Yu found that this underground building may have been abandoned for a long time, and the ground inside was covered with a thick layer of dust.

Finally, the entrance was found near the mountain wall not far from the south side of the waterhole, but at this time, the entrance was completely buried in the ground, and at a glance it was clear that it had been abandoned for many years.

But fortunately, the burial was not too deep, Lu Yu took out the mountain knife from the space and began to dig little by little at the entrance.

Yan Ruoxi, who was in the distance, saw that Lu Yu was busy and asked suspiciously, "What are you digging there?" Are there any treasures? ”

Lu Yu didn't look up, "That's right, there are indeed treasures, come and dig with me." ”

When a few girls heard that there was a baby, they immediately came over curiously and watched Lu Yu digging little by little with a knife.

"Brother, is there really a treasure here?"

"Of course, otherwise I'll have nothing to do and dig and play with my food."

"That might be."

"If you don't help pull it, don't blame me for finding the baby and not giving it to you when the time comes."

"Hee-hee, I'm just saying, come, I'll dig with you."

With the addition of three girls, the speed suddenly became much faster, and after a while, something was dug up, which was a big square rock. There is also a carved pattern on the top, and it looks artificial.

Now the girls are more excited, and there are really things, and they dig harder.

Suddenly, Lu Yu smelled a burnt smell and exclaimed, "Oh, it's not good." ”

"What's wrong?" Several girls looked at him suspiciously.

"It's a mess." Lu Yu pointed to the smoking rice pot in the distance and said with a smile.

Yan Ruoxi waved her hand indifferently, "At this time, where can I still take care of the rice pot, hurry up and dig to see what treasure is hidden inside." ”

"That's it, that's it, hurry up and dig it, and then you don't care about what to eat."

What you said makes so much sense, I don't know who it was just now, saying that I was hungry and worried that I didn't have anything to eat.

The entrance to this underground building is very large, and several people dug for an afternoon, digging down more than two meters deep, before digging out the entire entrance, which can be regarded as a few people who have cultivation, otherwise it will take several days to dig so deep with a sword.

This stone door is about two meters high and about three meters wide, it looks very heavy, and some patterns are carved on each door, but it may be that the time has passed, and these patterns have been blurred.

The stone door was closed, and there were two handles on it that could no longer be seen of any material, Lu Yu observed the entire stone door, turned to a few girls and said:

"You go up first, and I'll open the stone gate and see."

"Then be careful."

"Hmm."

After several girls went up, Lu Yu pulled the stone door lightly, and found that he didn't pull it, and increased his strength a little bit, and suddenly the stone door made a creaking sound, but it still didn't pull it open.

"Brother, why don't you push it and try it?" Lu Xiaoxiao suggested above.

"What nonsense? Whose door do you see pushing in? There is no common sense of life at all. As he spoke, he pushed it with his hand, so as to prove to Lu Xiaoxiao that the push could not be pushed. As a result, I didn't expect to be slapped in the face.

As a result, Lu Yu pushed, I wiped it, and it was really open, and it didn't bother at all. This face hits, snaps. Several girls couldn't hold back their laughter.

Lu Yu's face darkened, Nima, who didn't play cards according to the routine, held his breath, and after pushing the two stone doors open, Lu Yu jumped up and jumped up directly.

"Let's go in after a little ventilation." This kind of place that has been closed for a long time, the smell inside must not smell, and there are a lot of toxic gases, if you rush in, it is very likely to be poisoned, although Lu Yu is not afraid, but it will not be okay to be poisoned.

About half an hour later, under the anxious urging of several girls, the group walked into the stone gate, Lu Yu lit a torch for lighting, and as soon as he entered the door, a smell of decay and decay suddenly came to his nose.

After entering from the stone gate, it is a short stone passage, walking along the passage for about four or five meters, after passing the passage, it is a small circular hall, the small hall can be about 100 square meters.

There is a painting hanging on the wall facing the passage in the small hall, this painting is a little conspicuous in this dimly lit little hall, as soon as you enter the room, you can see at a glance, in the painting is a woman, holding a sword, is dancing a sword, although it may have been a long time, but this painting is still clear as new, and the woman in it is also lifelike, as if to fly out of the painting.

Underneath the painting is a stone table with a teapot and several cups, which are already covered with dust and look like they were. There is a closed stone door on the left and right sides of the stone table, and it looks like it should be a room.

Lu Yu looked around the entire small hall and found that there were a total of five stone doors, and he didn't know what they were used for.

In the center of the small hall, there was a round stone, the size of a basketball. Lu Yu stepped forward to wipe the dust off the stone. When I looked at this stone, my jaw almost fell to the ground in shock.

What kind of stone is this, this is actually a Neng Yuan Stone, but this Neng Yuan Stone has been cracked, and with a light touch, it has broken into several pieces, even so, it is worth a lot of money.

"Wow, Neng Yuanshi, get rich, get rich." Lu Xiaoxiao looked at Neng Yuanshi on the ground with a look of wealth and exclaimed, she has always cherished the piece that Lu Yu gave her, but unfortunately that piece is too small for her now, it is not enough, I didn't expect to meet so many here.

Yan Ruoxi also squatted on the ground, picked up a piece and looked at it, "Is this the Neng Yuan Stone?" It's the first time I've seen it. "She'd heard of it, she'd seen it in pictures, but it was the first time she'd seen it.

"If it's a whole piece, it's worth something unimaginable." Lu Yu sighed and said.

Although the Nengyuan Stone will automatically recover, if the spiritual power in the Nengyuan Stone is consumed in an instant in a short period of time, then they will be broken, and the larger the Nengyuan Stone, the more energy, so it is naturally a big piece of money.

"Brother, look here, there are a few smaller ones." Lu Xiaoxiao picked up a fist-sized Neng Yuan Stone on the edge of a wall and said.

Not only her, but there were several pieces near the wall, Lu Yu counted them, there were a total of 5 small ones around, and there was such a big one in the middle. What does that mean? Could it be the legendary big formation?
