Gu Yun walked over and touched it with his hand, which was considered to be abnormal.

Liu Ruyan saw Gu Yun's movements and asked curiously, "Gu Yun, what did you find?" ”

"I found that the recessed stone walls here are hotter than the surrounding stone walls, and there must be something on the other side of the stone wall that can heat up!" Gu Yun explained, then took out the tiger tooth saber and tried it, but he couldn't dig it at all.

"I'll try!" Liu Ruyan volunteered to come over.

Gu Yun stepped aside. I saw Liu Ruyan standing still in front of the stone wall, lifting a breath of true qi, and slamming her palm on the hot stone wall. However, apart from some dust being knocked out, the stone walls did not move at all. Liu Ruyan didn't believe in evil and tried it with both palms again, at most, she let some stone slag fall around, and the stone wall was not damaged at all.

Gu Yun was going to try it with a grenade again, so he said, "Senior sister, you go over there and hide, I'm going to use something very powerful." Stay away, but don't hurt you! ”

"Gu Yun, what are you going to use again?" Although Liu Ruyan asked, she still walked away obediently.

"Senior sister, you step back a little further! Cover your ears! Gu Yun commanded Liu Ruyan, and he was not relieved until she retreated nearly 80 meters.

Liu Ruyan hid to the side, Gu Yun took out a grenade and tried it on the edge of the recessed stone wall, which could be put on. So, he relieved himself to pull the ring of the grenade, put the grenade on it, and then instantly traveled back to Earth.

Boom –

There was a powerful explosion, a puff of smoke and stone dust, and a crack was blown into the hot stone wall.

At the same time, the ancient clouds on Earth immediately activated the altar and prepared to travel back to the cave. I saw that in the projection around the altar, as the bomb blew a crack in the stone wall, the projection of a square passage was displayed there, and there were many oil lamps lit on the wall of the passage.

Seeing the projection behind the crack, Gu Yun knew that he could "teleport" over. The projection around the altar is equivalent to a 360-degree panoramic view of the place that the human eye can see, centered on the crossing point. If you can't see it, you can't locate it, and you can't "teleport" it, which is also a major disadvantage of "pseudo-teleportation".

Gu Yun walked back to the cave first, and then shouted, "Senior sister, it's okay!" ”

However, there was no response from the place where Liu Ruyan was hiding. Gu Yun hurriedly ran over, where was Liu Ruyan's figure!

"Forget it, let's go over there and take a look at the passage over there!" Gu Yun was worried about the strangeness on the other side of the passage and decided to go over to visit first. Anyway, Liu Ruyan's skills are good, and she has the guns and ammunition he gave her, so there shouldn't be any danger.

After figuring it out, Gu Yun immediately teleported to the opposite side of the stone wall.

This is a passage, and the location where Gu Yun teleported over is the middle of the passage. He chose the direction to the left, and trotted along the passage.

Not long after Gu Yungang teleported over, two people immediately came to the stone hall where he and Liu Ruyan were resting, one of them was a white-haired old man, and the other was a white-clothed young man about twenty years old.

"Grandpa, this is the place where the bang just now!" The young man in white lit a torch and looked around the stone hall.

"It's here! Look at the stones falling over there! The old man nodded, and then said "Huh": "There is light over there!" ”

The young man followed the old man's gaze, and sure enough, he saw a faint fire in the crack in the stone wall, and immediately said in surprise: "Grandpa, it seems that this is really a treasure!" ”

The old man stood in front of the stone wall and ordered, "Ren'er, get out of the way, let the old man try this stone wall!" ”

Seeing the old man's movements, the young man knew that his grandfather was going to use internal force to forcibly break it. He hurriedly stepped aside, then stared at it deadly.

Boom - Boom -

The old man threw out a few palms, then rested for a while, and then blasted out a few more palms, and after about half an hour, the stone wall was blasted open with a hole for people to pass through. The old man took the credit, and then said: "This stone wall is a little loose, it seems that someone has tried it, I don't know why the road has stopped!" ”

"Grandpa, why do you care so much, let's go in and find out!" The young man stared at the entrance of the cave and said fieryly.

"Let's go!" The old man nodded, and went into the cave first.

Not to be outdone, the young man climbed in.

Gu Yun followed the passage and came to a stone chamber at the end.

This stone chamber is about 3 meters high, 5 meters wide, and about 7 meters long.

On the right side of the stone room, several long windows have been hollowed out, and there are weapons in them, about a dozen of them, almost all of them are swords.

Gu Yun was not interested in these cold weapons, and did not move them, but turned his gaze to the left.

On the left side of the stone chamber are nine small windows. Gu Yun walked in and saw that there was a book of martial arts cheats in every small window. Gu Yun casually took out a book and flipped through it, and found that the words in the martial arts secret book were all written in Han Li, and the graphics attached to it also had some flavor of ancient China.

Gu Yun looked at the past one by one and found that except for one internal strength and one palm technique, the rest were all swordsmanship and knife skills. It made him feel that maybe this was not the whole treasure!

Gu Yun casually received the internal strength, palm technique and a swordsmanship cheatbook in his bag. Looking at the other 6 cheats, he thought about it, and finally greed prevailed and stuffed them all into his bag.

Putting away the cheats, Gu Yun looked at the stone wall facing the gate of the stone chamber, because there was still a skeleton there.

The skeleton was sitting cross-legged against the stone wall. Although his clothes were rotten, he could still see the luxurious color of the past. And that posture of sitting cross-legged is the most common posture for a martial artist to cultivate internal strength.

Gu Yun walked over to take a closer look, and found that there was a line of small writing on the wall where the skeleton was leaning. The text is written in Han Li, which is quite beautiful.

"Those who come can be recognized by blood, if they are descendants of my descendants, they will have infinite benefits!" Gu Yun read the words out and thought: Could this be the mausoleum of the Zhenwu Emperor, why is it so shabby? Blood test? Where to drop blood and confess relatives?

Gu Yun searched carefully, and finally found that behind the stone wall where the skeleton was leaning, there was a small hole with a small mechanism embedded in it. I didn't see it just now, but I was blocked by the skeleton.

"Do you want to drip blood or not? Will I be a descendant of Emperor Zhenwu? Isn't that too bizarre? If you have tested it, you will know the way, even if there is any danger, just flash back to the earth! ”
