To Li Qing's surprise, the mural on the fourth stone wall is actually a map, yes, Li Qing can be sure that this is definitely a map, and it is also a world map, although this map is not complete, but Li Qing can still vaguely distinguish that the territory of this map has reached Europe, crossed the Mediterranean Sea and the Alps.

"Could it be that Lao Tzu really went to the West when he sent a letter to Guguan? Why did he go to the West? Is it because of the silkworm bush? I remember that Qing also said that Silkworm Cong went to the West at the invitation of a friend, and now Lao Tzu has also gone to the West, the West, what is there, why do they all go to the West? What's in the Alps? ”

Li Qing fell into deep thought, and Old Man Gao and Zhang Hu couldn't understand this map at all, they saw Li Qing's solemn expression, and they didn't dare to ask more for a while, Old Man Gao moved to the side of the futon by himself, and sat down to rest.

Li Qing carefully studied the map and found that there were several strange flame marks on the map, Li Qing felt that this mark must have some special meaning, and hurriedly wrote them down in his mind.

"Mount Kunlun, the Alps, Mount Olympus, why do these three mountains have flame marks, and does this have any special meaning?"

Li Qing thought in his heart, Kunlun Mountain, known as the ancestor of ten thousand mountains, Kunlun Mountain Range, is the dragon vein of the whole of China, the status can be described as supreme, and the Alps is the highest mountain range in Europe, there must be some connection between the two, as for Olympus, it is known as the origin of Western civilization in later generations, can it be said that this flame symbol has any special meaning.

"I'm so hungry, there are tigers guarding the entrance of the cave, how can we get out?"

Zhang Hu rubbed his stomach and said with some concern.

Zhang Hu's words brought Li Qing's thoughts back to reality, the three tigers at the entrance of the cave can't be defeated, and in this cave, there is no food and water, and the three of them will starve to death and die of thirst in a short time.

"Zhang Hu, let's find out if there are any other exits."

After Li Qing finished speaking, a wry smile appeared on his face, this stone room was very simple, it was simply a boxy box, except for the round ball of light above, there was no other place that could be an exit.

Zhang Hu also looked up at the sky above, and Zhang Hu noticed the magical scene in the sky as soon as he came in, but compared to Li Qing, Zhang Hu didn't have any concept of planets in his mind at all, he just felt magical, and nothing else.

"Sir, why do you think they move?"

Zhang Hu pointed to the round ball that radiated light in the sky and asked, and the old man on the side smiled when he heard this: "This is the means of the gods, how can Li Xiaozi understand." ”

Li Qing didn't pay attention to the old man, according to Li Qing's understanding, the ball of light above should be a magical meteorite, I don't know what method the owner of this cave used to get rid of the shackles of gravity, and then they can still rotate according to the predetermined trajectory, this kind of thing, if it happened in the later generations, with the technology at that time, it was not difficult to do this, but in this ancient world, it can really be called a fairy means.

Li Qing said: "This should be a meteorite, as for why the meteorite can be suspended in the air, I don't know, but it doesn't matter, we don't have wings, and it is impossible to fly to it, let's see if there is any other place to go out." ”

The old man pointed to the big tripod in the middle and said, "Well, this tripod has not been opened, maybe there is something in this tripod that can help us get out." ”

Old man Gao's words were not completely unreasonable, but looking at Da Ding, Li Qing felt a headache, because Da Ding had no way to open it with brute force, and the only way to open Da Ding was to find the mechanism on Da Ding's body.

"Huh?"

Li Qing suddenly looked at the Tai'a sword on his waist, the Tai'a sword was as sharp as clay, and he might be able to use the Tai'a sword to forcibly split this big ding.

Li Qing thought about it, pulled out the Tai'a sword, and slashed at Da Ding fiercely, only to see the firelight splashing, Li Qing felt a numb palm, and then looked at Da Ding, there was no damage at all, not even a small scratch.

"It's hard."

Li Qing exclaimed, but fortunately, the Tai'a sword was not damaged, otherwise, Li Qingke would have cried.

Li Qing stroked the big ding, before Li Qing only noticed the tripod cover, but now Li Qing found that this tripod body was actually engraved with strange words.

"Even the Tai'a sword can't leave a mark on this big ding, what are these words engraved with? Isn't that scary? ”

Li Qing carefully identified the words on it, and after a while, Li Qing could only spread his hands helplessly, although Li Qing had studied ancient characters for a period of time, but the words on this Dading were not ordinary hieroglyphs at all, it was more like a kind of ciphertext, and if you couldn't find the right way to interpret them, it was impossible to interpret them.

"Sure enough, archaeology isn't that easy."

Li Qing said self-deprecatingly, now he really looks like an archaeologist, but the things he investigates are a little appalling.

"This big tripod won't be the same as the big tripod on the mural."

Li Qing suddenly had such a thought in his mind, after all, there are not many things in this world that are harder than the Tai'a Sword, this big tripod should be considered rare in the world in terms of hardness, such things should not be many, and with the volume of this tripod, it is impossible for ordinary people to get this kind of hard material and use it to cast the tripod.

Li Qing came to the mural again and watched the big ding on the mural, on the mural, the man who was suspected of being a silkworm bush was adding fire to the ding.

"No, it's not adding fire."

Li Qing suddenly noticed that something was wrong, the silkworm bush on the mural stretched out his hand, it did look like he was adding firewood to Dading, but after looking closely, he found that it didn't seem to be so simple, it seemed to have a different meaning.

Li Qing had an idea, came to Da Ding, learned the appearance of the silkworm cong, reached under Da Ding, and then touched his hand to the bottom of the Ding.

"There's something."

Li Qing couldn't help but show joy, and then asked Zhang Hu to bring an oil lamp, Li Qing wanted to see what was depicted on the base of this big ding.

Zhang Hu brought an oil lamp, and I don't know what the oil in this oil lamp is made of, I don't know how much time has passed, but it can still burn, and there is still half a full half of the lamp oil in the entire oil lamp, which shows the degree of burn resistance of this lamp oil.

With the light, Li Qing saw the bottom of the big tripod, the bottom of the big tripod actually happened to be the solar system and the nine planets, but their positions were out of order.
