The swishing cold air came to the face, and the more you went into the cave, the more cold and piercing it became, as if you had entered an ice cellar, making people shiver.

"Boom!"

A sharp and piercing thunder, lightning pierced the night sky, making the already quiet night a little throbbing.

Thunder and lightning, after half a pillar of incense, boom, boom, heavy rain poured, rain and wind, thunderstorm.

The lightning outside the cave illuminated the night, and unexpectedly, the ruins would enter the night when it was dark. The light was projected into the cave, and Zhang Ziyu and Yuyin walked cautiously inside.

Then the electric light, I saw that the rocks on both sides of the cave were strange and rugged, extremely steep, and each rock seemed to be a monster lurking there, especially some strange-shaped rocks, like a fierce beast that opened its mouth to reveal its white teeth, which made people shudder.

And the further you go into the cave, the more precipitous it becomes, the more difficult it becomes, and the colder it becomes. However, the two of them could only go to the cave. Because it is nightfall outside, and there is thunder and lightning storms, at least in the cave there will be no rain and beasts, even if it is cold, it is safe.

However, the more she went inside, the more Yuyin frowned, and a little uneasiness and trepidation lingered in her heart. For many years, she has been cultivating the Nine Secret Techniques in the "Back Yin Mountain", and the extremely cold place is no stranger to her.

However, the caves in this sacred mountain are much colder than those of the inherently dangerous places like Beiyin Mountain. There must be something weird, she silently told herself in her heart, and also told Zhang Ziyu. And there was a little fear in her heart, which she had no other way around.

It should be said that for her, who cultivated the Nine Secret Techniques, entering such a cold place was a joy for her. Her long-term cultivation has not only adapted to the cold place, but also made her body accustomed to the cold.

"Sword Spirit, I remember, before coming out of the Earth Dragon Sect, there was a doctor in a medical hall who went to find Shizun, the Heavenly Mandate Medical Hall, yes, that's the name!" Suddenly, Yu Yin remembered something and hurriedly said.

"Uh, didn't you say that this cave is weird, why did you suddenly think of the Heavenly Mandate Medical Pavilion again?" Zhang Ziyu asked suspiciously.

"It's because I think of the Three Realms, who else can make Shizun come out in person!" Yu Yin explained.

"Are you saying that the doctor of the Heavenly Mandate Medical Pavilion can make your master come out?" Zhang Ziyu was suspicious, remembering that the Black Tiger had said before that it was Yuan Shumu of the Heavenly Mandate Medical Pavilion who sent the Earth Dragon Sect to hunt them down.

This is exactly the same as what Yu Yin said, could it be that the mastermind behind the killer of the Earth Dragon Sect is really Yuan Shumu of the Heavenly Mandate Medical Pavilion, and the black tiger said that Yuan Shumu is not a disciple of the Dao Sect, but an immortal in the pot who is in charge of the strange time and space of the demon refining pot.

Yu Yin nodded, and then said, "I believe that Yuan Shumu, the self-proclaimed doctor of the Heavenly Mandate Medical Pavilion, must have something else to hide. Maybe he wasn't a doctor at all, but a legendary fairy in the pot. ”

Zhang Ziyu was stunned, a little unable to believe his ears, but asked rhetorically: "Why?"

"In addition to the cold moon in the Cold Moon Palace, there is this immortal in the pot, which the master is more concerned about. Cold Moon is the only Nine Tripod Power Emperor Ding level cultivation in the Three Realms, and her master's cultivation is far inferior to her. can only bow to the wind, and the immortal in the pot, it is said, has something to do with the master. ”

Zhang Ziyu thought to herself, if Yuyin knew about Hanyue and the Immortal in the Pot, then she must know a lot of information about Hanyue and the Immortal in the Pot.
