Seeing the mysterious runes appearing on the stone door, Lao San was stunned.
"This stone gate is guarded by runes?"
In the more than a hundred years since he was born, he has been to this barren valley countless times. He never thought that this abrupt black stone would have such a secret.
Although he had already learned from his elder brother that there was a mysterious cave here, he only imagined a secret primitive cave or something like that, but he did not expect that it was a cave guarded by mysterious runes.
Seeing the surprised expressions of the second and third children, the boss smiled slightly.
The third child was anxious.
"Brother, please stop being so secretive and open the stone door quickly."
The third child's curiosity aroused, and all he could think about at the moment was that there were many treasures in the cave, and he was eager to take a look.
"Hey, you are so impatient, when will you change it?"
The old man laughed and said, his body suddenly rose up from the ground, flew to the stone wall dozens of meters high above the stone gate, and pressed down a protruding black rock with his hand.
Then there was a "rumbling..." sound, and the huge stone door slowly opened.
A cold air came out of the cave, with a slight musty smell.
Yang Xiao looked towards the cave. The huge cave was pitch black and nothing could be seen.
The third child laughed, walked quickly ahead, and rushed into the cave.
The second child followed closely behind, while Yang Xiao walked behind with the eldest child.
It was cold, damp and dark inside the cave.
The boss raised his hand, and a ball of fire appeared on his palm. The cave suddenly shone with light and became much brighter.
With the help of light, Yang Xiao took a look and found that the stone walls of the cave were the same as the rocks outside, dark and cold.
He secretly took a selfie with his hand. Although he could break the rocks, the rocks were relatively hard and he didn't know what material they were made of.
A group of four people walked about two kilometers in the cave. The cave suddenly became wider. As they continued to move forward, a huge hole appeared.
With the help of the fireball light of the Xuanbing Pterosaur boss, Yang Xiao made a visual inspection and found that the width of the cave reached five to six hundred meters, and it stretched forward with no end in sight.
This is somewhat similar to the mountain caves on the earth, except that the caves on the earth are all limestone, but the caves here are made of dark crystal-like stones.
Moreover, traces of artificial construction can be clearly seen in this cave.
"Brother, come quickly, there is light here!"
The third child's excited shouts came from the distance.
Yang Xiao and the eldest brother were walking behind, now hundreds of meters behind the third and second eldest children.
The boss of Xuanbing Winged Dragon was calm and said with a smile:
"Oh, the third child just has an impatient personality. He has been like this since he was a child."
Yang Xiao said:
"He may have forgotten that you, senior, have been to the cave a long time ago,"
As soon as he finished speaking, Yang Xiao suddenly felt a strange feeling in his body, his mind moved slightly, and he was very surprised.
Yang Xiao once practiced in the Ice Lake Cave and Windblade Valley of Shendu College, where there is strong evolutionary energy.
From the moment he entered the cave, he felt something different. At this moment, he was running his mind detection and felt a powerful wave of energy.
"Senior, this cave seems to have a powerful energy fluctuation,"
The boss of the Xuanbing Winged Dragon held a huge fireball in one hand, and the firelight illuminated his white beard. He laughed and said:
"Boy, do you feel it?"
"Yes, I felt it from the moment the cave door opened. But after entering here, I feel that this energy is getting stronger and stronger."
"Well, let's go to Lao San's place first to see what this guy is doing."
The figure of the Xuanbing Winged Dragon boss flashed forward and swept forward.
Seeing that the boss didn't elaborate, Yang Xiao couldn't ask further questions, so he could only follow him and fly forward.
A huge light appeared in front of my eyes.
Thousands of square meters of circular cave, with six watermelon-sized balls on the top of the cave, emitting bright light, illuminating the entire cave as if it were daytime.
The third and second children were looking around excitedly in the cave.
"Brother, come and tell me, what is this?"
Seeing the boss coming, the third child waved to the boss impatiently and shouted loudly.
Yang Xiao and the Xuanbing Winged Dragon boss walked over and stood next to the third child.
The third child pointed at the dark stone wall.
Yang Xiao took a closer look and saw some murals carved on the dark stone wall.
"Brother, what are these murals about?"
The second brother of Xuanbing Pterosaur also ran over.
The second and third children looked around in the cave and could not understand the paintings on the stone walls. They thought that since their father told the eldest brother before his death, the eldest brother must know the secrets on the stone walls.
The boss of Xuanbing Pterosaur no longer needed to drag the fireball. He put his hands behind his back, looked at the mural on the stone wall, and said with a smile:
"If you ask me, I don't know either."
"Didn't father tell you?"
"No, my father brought me in twice before he was alive. He just told me to take good care of this cave, and nothing else."
"that's all?"
The third child looked disappointed.
I ran in with eager curiosity and saw the paintings on the stone wall, but I didn't understand anything.
The third child suddenly looked at Yang Xiao and saw that Yang Xiao was looking at the mural seriously, so he asked:
"Brother Yang, can you understand?"
Yang Xiao was stunned for a moment, then turned around and said:
"I'll have to see it first to find out."
The Xuanbing Pterodactyl boss felt something in his heart. He knew that Yang Xiao was from another civilized planet, and his level of civilization far exceeded that of the three Xuanbing Pterodactyl brothers.
Objectively speaking, since the ancient continent was sealed, all the monsters in the continent have been monsters. Even if they have evolved into human form, their cultural level is still very low, and they lack understanding of many common sense knowledge, let alone words and pictures. .
The boss made a gesture to the third child, telling him not to disturb Yang Xiao.
Yang Xiao concentrated on looking at the mural.
The mural depicts rolling mountains, a huge Godzilla tribe living among them, and a red sun in the sky.
This should be a description of the life of the Godzilla tribe in the ancient continent tens of thousands of years ago.
After Yang Xiao finished reading this mural, he took a few steps forward and came to the second mural.
A huge round object fell from the sky.
Some people walked out of the round object.
This should be a description of tens of thousands of years ago, when similar aliens landed on the ancient continent, or landed on a dwarf star.
Among the information currently available to Yang Xiao, he does not know whether the humans on the dwarf star came from aliens tens of thousands of years ago or evolved naturally.
Immediately afterwards, Yang Xiao walked to the third mural.
On the mural, humans and Godzilla are at war.
In the melee scene, there is a man holding a giant sword and cutting off the head of a Godzilla.
A Godzilla spits fire, and the flames sweep through the human village.
Judging from the murals, this was a brutal melee of life and death between the two sides.
Yang Xiao walked to the fourth mural again.
