"Xu Fu, why is it him again..."Lin Xiaoxiao couldn't help but say, a few people went on an expedition before, it was the clue left by Xu Fu, and now the treasure map placed in the Qishuang unit building has not been cracked, and I can't imagine that the Mausoleum of Qin Shi Huang, who was explored first, is inseparable from Xu Fu.

"Is there any problem?" asked Meng Na, keenly sniffing some information.

Lin Xiaoxiao explained vaguely, "We explored two treasure places before, which were also left by Xu Fu, so we were surprised. "

"Is that where you got the treasure that allowed you to form an alliance?" Meng Na asked quietly.

"That's right..."Lin Xiaoxiao nodded.

"Oh," Meng Na surprisingly didn't say anything more.

Lin Xiaoxiao looked at the mermaid and continued to ask, "Why did Xu Fu turn you like this?"

"He made us take a pill and said we would live forever, and then we became like this. "Mermaid Road.

"Just let you wait here?, could it be that you just guard the immortal fruit tree?" Lin Xiaoxiao muttered secretly, Leng Yulu and Qi Shuang were also thoughtful, but they couldn't think of anything after all.

On the other side, Zhao Longtian killed almost the fish, and the floating in the waterhole was full of those mermaid corpses.

"It's finally done..."Zhao Longtian let out a turbid breath, saw that nothing appeared again, and began to work hard to pull out the immortal fruit tree. Not long after, Zhao Longtian pulled out the immortal fruit tree from the black water pool and transplanted it to the storage ring.

Under the immortal fruit tree, there is a black stone slab. There is a sword hole on the black stone slab, which looks more consistent with the Dingqin sword.

"The entrance lock of the Mausoleum of the First Qin Emperor was so easy to find?" Zhao Longtian was a little incredulous, did happiness come too suddenly. After being surprised, Zhao Longtian took out the Dingqin Sword and inserted it into the sword hole.

A white light emitted from the Dingqin Sword, and soon enveloped the stone slab and the Dingqin Sword, the black waterhole began to roll, the surrounding fog slowly gathered in this direction, and wisps of black gas on the mermaid's corpse also floated over.

When the vision appeared, Qi Shuang was asking the mermaid why he didn't eat the longevity fruit. After the mermaid's explanation, she finally knew that Xu Funa's elixir could make them live for 5,000 years, and the longevity fruit was chicken ribs for them, and it was useless at all. Besides, they have long wanted to die because their heads are too hard to touch the wall, and their companions can't bear to do anything to each other, so everyone is afraid of dying in the end, lonely and have no playmates.

According to the mermaid, everyone wants to live forever, but in the face of endless lonely years, they are uglier than ghosts, and it is more painful to live than to die.

"What's going on over there?" Qi Shuang noticed everything that happened in Heishuitan and couldn't help but ask.

"Zhao Longtian found the entrance mechanism of the Mausoleum of the First Qin Emperor. Lin Xiaoxiao spoke, staring at the direction of Heishuitan without blinking. She noticed that the mermaid killed by Zhao Longtian had melted into a black liquid. At the same time, the mermaid in the energy shield hissed, and its body slowly melted.

"What's going on?" Lin Xiaoxiao said, looking back at the mermaid.

The merfolk screamed in pain, and little by little, its body melted into a black liquid that flowed towards the edge of the energy shield.

When the black liquid touched the energy shield, it corroded the energy shield, but it did not corrode the ground.

Leng Yulonely sighed, "I don't know what Xu Fu did in its body before." This kind of immortality is really meaningless. "

"It's not that unbearable, I have lived for thousands of years, and it is nothing to suffer from this, you see ordinary people live old and sick and die, and some are still tortured by illness after living for decades. "

Lin Xiaoxiao spoke, and suddenly said, "What is that..."

Following Lin Xiaoxiao's gaze, he saw a few dark golden particles floating, those particles were square, about a cubic millimeter, and the black liquid that corroded everything did not corrode it.

"Yaojin, most of the ancient refining pills used cinnabar (mercury sulfide) and medicinal gold (composed of gold and copper) to color, I think this should be the medicinal gold left in its body after it consumed the pills. Meng Na said.

"I'm not asking what kind of substance it is, I'm saying that you have noticed that there is a breath of life and a bit of death on those medicinal gold..."Lin Xiaoxiao explained, it was medicinal gold, how could she not recognize it, Lin Xiaoxiao was not unreadable, no matter how she said that she was also a child of a big family.

"The breath of life and the breath of death?" Leng Yuliao sensed it carefully for a moment, and said, "That thing can live for thousands of years just now, isn't that what it does?"

"I'm afraid, why don't we take this thing out and study it?" Meng Na's face was full of yearning.

"How can we study it? Xu Fu is the Sect Master of Qin Shidan, and there are very few people in the contemporary era who can do it, and it is impossible for us to meet those people, let alone give them something to study. "Cold rain lonely waved his hand...

The black liquid that corroded the energy shield finally corroded the energy shield of Leng Yu and several people into a hole, and through this opening, the black liquid flowed into the black pool. Tumbling with the liquid in the black pool, like boiling water.

After a long time, the black water pool calmed down. The light of the Dingqin Sword also subsided, and it actually melted slowly.

The dark energy around was almost surging, and the entire cave had a wide field of vision, and at a glance they could see the end, Zhao Longtian, Lin Xiaoxiao and the others finally saw the stone gate and the stone man that Ye Xiangqi said.

The stone doors are all closed, and the stone people are all closed.

The Dingqin Sword was still melting, and Zhao Longtian vaguely saw a touch of golden light, as if there was something wrapped in the Dingqin Sword.

"What the hell is it?" Zhao Longtian stared at Ding Qin Jian with a good face, and a few people from the bored Lin Xiaoxiao flew over. Lin Xiaoxiao carried Qi Shuang and hovered beside Zhao Longtian, Zhang Shudong carried Lao Hei, Meng Na carried Ye Xiangqi, and Leng Yulu was alone.

Finally, the Dingqin Sword melted in the eyes of several people, and what was wrapped in it was a golden key. The golden key was about ten centimeters long, and it was carved with some strange patterns.

"Leng Yulone, don't you think this is a bit like the medicine just now?" Lin Xiaoxiao couldn't help but say.

"It's a bit like, there is the breath of life and the breath of death. Leng Yuliao nodded secretly and said, "I think Xu Fu trapped those three-born fish here, I'm afraid he is hiding this key, what is he doing so carefully, and making it so cumbersome." "

Leng Yulonely naturally thought of the chain of secret places they explored, one link after another, and they couldn't break some of them at all. Otherwise, you won't be able to find the ultimate goal.

"This can only be known if we crack it step by step, it's really a little bit of a little expectation, what treasures have been left to us by the former heroes. Lin Xiaoxiao sighed.

Meng Na waited for Lin Xiaoxiao to finish speaking, and said, "Xiaoxiao, can you take me and Xiao Zhang with you when you crack the secret?"

"This..."Lin Xiaoxiao hesitated slightly, and glanced at Zhao Longtian, no matter how much it was a treasure, bringing two more people would weaken his own interests.

"I know you're having a hard time, if you don't, forget it. Meng Na said with a slight disappointment.

"I can take you with me, but I can only give you a share of it every time. Zhao Longtian spoke, he felt that such an opportunity could increase his strength, so that Meng Na and Zhang Shudong would be more willing to help him in the future. Besides, if you think about it carefully, most of the things left by Xu Fu have a treasure map, and there may be one for this tomb visit. Even if the treasure map in Qi Shuang's house is not mentioned, the treasure map here must be taken out and shared, and no matter what, Meng Na and Zhang Shudong have to be brought together, so that now it is agreed to leave a good impression on Meng Na and Zhang Shudong, so that they can be grateful to themselves from the bottom of their hearts...
