The first two murals made Li Qing have some guesses about the owner of the cave in the murals, and in the third one, Li Qing verified his guess.

In the third mural, the picture changes, three humanoid figures with swords surround the person preaching on the stone wall, and on the ground, there are several people lying down, as if there is a battle between them.

In the fourth mural, an exaggerated tiger pushes three sword-wielding figures to the ground, and on the tiger's back, sits the preacher, and behind them, some other strange beasts can be faintly seen.

After looking at the mural, Li Qing touched his chin and said: "I probably know what the mural wants to express, that is to say, the owner of this cave once accepted a lot of apprentices here, but I don't know why, these apprentices suddenly rebelled and wanted to kill the owner of this cave, but they were later killed by the strange beasts raised by the owner of this cave, it seems that the owner of this cave is also a ruthless person." ”

"Why would they want to kill the cave's owner?"

Zhang Hu asked suspiciously, in Zhang Hu's opinion, the owner of the cave was obviously their master, and it was too rebellious to kill the master with his apprentice.

Old man Gao suddenly pointed to the mural at this time and said loudly: "I know, it's because of immortality, you see, the difference between these people in this second mural and the third mural?" Look, are there three lines under their heads? If this represents a beard, it means that these people are old, but if you look at the owner of the cave, he has not changed in the slightest from beginning to end, which shows that the owner of this cave is really an immortal, he can live forever, but he has not passed on his immortal skills, so his apprentices will rebel and want to kill him. ”

After listening to Old Man Gao's words, Li Qing's heart moved, and sure enough, all the human figures in the mural would have slight changes, but the owner of the cave had not changed in the slightest.

Li Qing walked quickly to the north stone wall, on this stone wall, there are still four murals, the first one, the cave owner is sitting alone on the edge of a cliff, behind him, only a big tiger is accompanied, and the other strange beasts have disappeared.

In the second picture, the owner of the cave is cutting his arm with what looks like a dagger, and in front of him, the tiger is lying on the ground, hanging its head, according to Li Qing's understanding, it should mean that the tiger is dying.

The third mural is a picture of the tiger roaring in the forest, the tiger in the mural looks very majestic and mighty, on the back of the tiger, the cave owner sits cross-legged.

In the fourth mural, the tiger stands alone in front of a cave where the owner of the cave is riding a cow towards the place where the sun rises.

"What does that mean, sir?"

Zhang Hu couldn't understand the meaning of the mural, so he couldn't help patting Li Qing's arm and asked.

Li Qing was taken aback by his thoughts, and even showed a hint of horror on his face, he didn't answer Zhang Hu's words, but looked at Old Man Gao and asked, "Elder Gao, do you know how many years old is the legend of the Immortal Cave?" ”

When the old man Gao heard this, he said with a smile: "The history is old, according to my grandfather, the earliest is in the Eastern Zhou Dynasty." ”

"Eastern Zhou period!"

Li Qing's heart was beating violently, if the legend is true, then that is to say, the owner of this cave is likely to be a character in the Eastern Zhou Dynasty, you know, the Eastern Zhou Dynasty lasted more than 500 years, Li Qing thought of the huge white tiger outside the cave, and his heart was secretly speechless, if the tiger in the mural refers to the white tiger outside the cave, isn't that white tiger has lived for hundreds of years?

"Wait, bull riding, bull riding, the master of bull riding in history, could it be that the owner of this cave is Lao Tzu?"

Li Qing's heart moved, if the image of the owner of the cave in the mural is indeed very consistent with the Taoist record of Lao Tzu.

"Come and see, look here."

Originally, Li Qing thought that since the murals on the north side had recorded the departure of the cave owner, there should be no murals on the other two stone walls, but he didn't expect that on the stone wall of the west gate, Zhang Hu found the murals again.

There are still four murals, but compared with the previous murals, the murals on this stone wall are relatively simple.

The first mural is a man wearing a strange mask and a silkworm coiled over his shoulder walking in a place that looks like a tribe, and everyone is worshipping and worshipping, except for one person who looks like a child looking at the masked man.

In the second mural, a group of men with the heads of wild beasts are slaughtering the original tribe, and everyone in the tribe is dead, except for a child crouching at the bottom of a well.

In the third mural, the masked man reappears in the tribe, burying all the corpses, and the child, on his back.

In the fourth mural, a tripod appears, and the man wearing the mask is adding fire to the tripod, and the child has disappeared and is replaced by an adult, apparently, the child has grown up.

"Look at the meaning of this mural, this should be the cave owner's childhood, the cave owner was born in one tribe, his tribe was slaughtered by another tribe, this masked man rescued the cave owner who was still a child, and then raised him."

Li Qing said, suddenly looked at the mask man carefully, Li Qing found that this mask man was very similar to the statue of the silkworm cong he saw in the Tang Valley, especially the silkworm coiled on his shoulder, which made Li Qing confirm the identity of the mask man on the mural, the silkworm cong.

Li Qing didn't explain the story about Silkworm Cong to Zhang Hu and Old Man Gao, but in his heart, there were already waves, Lao Tzu was actually Silkworm Cong's apprentice.

Li Qing already knows that Silkworm Cong is a human being from the future, and has mastered the real method of prolonging life, and judging from the murals, Silkworm Cong should indeed be able to prolong people's life, which is why Lao Tzu's apprentices are old, and Lao Tzu is still young.

"This Ding ......"

Li Qing and the three of them set their eyes on the big tripod in the middle of the stone room at the same time, this tripod is the same as the tripod in the mural, so that is to say, inside this tripod, it is really very likely that it is an immortal medicine that can make people immortal.

Even Li Qing scoffed at the so-called immortality, but at this time he couldn't help but have some doubts, maybe there is really some kind of substance in this world that can make people live longer and stay young forever, after all, the white tiger outside the cave has confirmed the authenticity of the murals in the stone room.

"By the way, look at what the last mural records, maybe there is a way to open the big ding."

Li Qing said, walking towards the stone wall in the west, wanting to see what kind of story the mural on the west side recorded.
