"Why are the doors of these prisons open, some of them have bones in them, and some of them don't even have bones?" asked the spirit curiously, the doors of each cell here were open, and some of them were empty, and some of them had a white bone on the stone platform.

"Could it be that Ying Zheng's conscience was discovered when he died, so he released all the people locked up here?" Wang Xueling thought about it and said, her heart still maintained the kindness and beauty of the world......

Li Zimu shook his head, how could it be possible, with Yingzheng's temperament, even if he knew when he would die, he would definitely not release these people before he died, and then the descendants of his Qin family would be finished.

"There is only one possibility, that is, Xiang Yu came here and released all the people here, as for the cell with white bones, it may be because he was already dead when he came, so he didn't deal with the corpse, and it turned into white bones after a long time."

Li Zimu said lightly, there is only this one possibility, otherwise it would not be possible to explain why these cells are open and some of them still have some white bones left.

"It seems that this Yu is still a loving and righteous person, but unfortunately in the end it was a tragic death in Wujiang" Wang Xueling shook his head and sighed, such a heroic figure, but the final ending was so tragic, leaving only a beautiful biography of the overlord Farewell Concubine to future generations.

Li Zimu smiled and didn't speak, if he had been in the past, he really didn't have a good impression of Xiang Yu, but since he went to the Overlord Palace, he had a new understanding of Xiang Yu, this person didn't seem to be as reckless as he imagined.

"You see, there's a sign hanging on top of each cell," said the spirit, approaching a cell and shining a flashlight on an iron sign, some of which she knew, and some of which she couldn't read.

"This is a name plate, and it is written that the people locked up inside are still related to the time when they were brought in" Wang Xueling looked at the name plate hanging on the cell and said, she also studied history, not like Chi Ling's half-pot of water, her historical knowledge is still very good, at least she can understand these small seals.

"Hmm, wasn't Qi Wangjian exiled as a concubine? Why is his name written on this nameplate?" Wang Xueling frowned and wondered, the historical Qi Wangjian was exiled by Qin Shi Huang.

"Ying Zheng won't be so kind to let the tiger return to the mountain" Li Zimu shook his head and said, exile is just a rhetoric to the outside world, with Ying Zheng's temperament of retribution, he will definitely not let a figure of the level of King Qi go unchecked, the latter's energy should not be underestimated, he will definitely not be stupid enough to do such a thing as letting the tiger return to the mountain.

"Then there are no white bones in this, which means that he was also released by Xiang Yu?" Chi Ling touched his chin and said, combined with Li Zimu's inference just now, the living people here were all released by Xiang Yu, so this King of Qi should have died of old age, right?

"It should be" Li Zimu nodded and said, no wonder their Tian family was so fierce at the end of Qin, it seems that the King of Qi behind them has been released, no wonder so many people are willing to help Xiang Yu, even if Xiang Yu dies, his descendants can live safely, I think it should be those people who were rescued by him who were secretly protected.

"These iron pillars are actually made of iron mothers...... Zhang Jingyang said in slight surprise, but he didn't expect that even the iron pillars of these cells were all cast by iron mothers.

"The people who are locked here should be strong in martial arts, and the general iron pillar can't stop it" Li Zimu said lightly, raised his feet and walked forward, there is nothing to stay in here, the surroundings are getting hotter and hotter, he simply took off the cotton clothes on his body, anyway, it has been cut by the sword.

"Exactly fifty cells," the spirit said with a smile, at this time they had already reached the last cell of this prison, and there was still an iron door in front of them, exactly the same as the previous two, and they were no longer surprised.

Fifty cells, it is completely enough to hold the masters of the six countries, looking at the iron door in front of him, there is still a sword-shaped groove on the door, and Li Zimu put the sword in his hand inside.

"Huh?" Li Zimu touched this iron door, the two iron doors in front of him have no temperature, and this third iron door, why is it so hot? Li Zimu was puzzled, took off the Tai'a sword, pressed his hands on the door and pushed it forward.

"It's so hot!" Zhang Jingyang hurriedly retracted his hand and said, he was originally helping Li Zimu push the door like last time, but as soon as he put his hand up, he felt a blazing temperature coming over, which made him retract his hand directly.

"I'll come" Li Zimu said without replying, took a deep breath, pushed the iron door with both hands, and pushed it out little by little, this temperature is hot for them, he is not enough, at most it is just a little hot.

After a long while, Li Zimu pushed open a crack for one person to pass through, turned around and picked up the Tai'a sword, and Li Zimu took the lead to walk outside the iron gate.

"Go down again, how deep does this stone dungeon have to be cultivated down here, don't you panic......" The spirit said speechlessly, as if they had already gone down a long distance.

"There is a ventilation system here" Li Zimu said lightly, and took the lead to go down, this kind of dungeon has a ventilation system, and the Overlord Palace also has it, and this stone dungeon naturally has it, perhaps more than the ventilation system of the Overlord Dungeon.

The four of them walked down one after the other, the stone steps were not very long, the flashlight could shine directly to the bottom, and below was a flat ground, and then the front was invisible.

"We can't be in the volcano, why do we feel so hot......" The spirit frowned and said, although it was a little hot before, but it was not so hot, since passing the iron gate, the temperature suddenly rose a lot, and several people took off their coats, it couldn't be too hot, just like a sauna.

After a few people took off their coats and put them on, Li Zimu began to walk down again, and after a while, he reached the bottom of the stone steps.

At this time, there was a passage in front of them, and a little further out, there was an open place outside, and a faint red light could be seen.

"Ahh......h

This passage turned out to be an air passage, and there were no walls on either side to protect it, and this passage was about two hundred meters long, and from here you could see that there was also a large semicircular hole on the side of the passage, exactly like the one behind them.

Li Zimu walked to the edge of the passage, lowered his head and looked down, and the red light shone from below.

Where they now stand, underneath this aerial passage, is a crater with a radius of about 100 meters, from which you can see red magma.

It's an active volcano hidden underground!
