Ran Su picked up a round key from an icicle next to him and turned it on the door.

The door opened, and an icy chill, with frost and light, rushed towards him.

A circular ice cave, surrounded by walls made of ice, the cold air on the wall turned into bursts of white smoke, wandering in this ice cave, here is about three zhang wide, there is a one-zhang sized ice pool in the middle, there is countless broken ice. The roof is made of luminous stone and white jade, which illuminates the whole house transparently, and you can clearly see that the top of the roof is a piece of water, and the water reflects the shaking light through the luminous stone and white jade.

The shocking project, Mu Lingtian and Luo Xue were dumbfounded.

Ran Su put down the lantern in his hand and walked into the ice cave.

"It's incredible that there is such a room, dare to ask my mother-in-law, is this under the Shattered Star Lake?" asked Luoxue in amazement, looking at the roof.

Ran Su nodded and said, "That's right, we are at the bottom of the Shattered Star Lake. ”

"Could this be the rumored craftsman Zhang Qianyan?" asked Luoxue in surprise.

"That's right, this is indeed built by the craftsman Zhang Qianyan. I am afraid that no one in the world can complete such a masterpiece except him. Ran Su also sighed, looked at Luoxue and asked, "The girl also knows Zhang Qianyan?"

Luoxue smiled, "I once heard people mention his name, and it is said that there is nothing he can't do. So, does my mother-in-law know Zhang Qianyan?"

"Once by chance, I saved his life, he had to repay me, I didn't know he was Zhang Qianyan at the time, and I thought he was very annoying, in order to get rid of him, I casually said, I want a room made of pure ice. Then he built the house for me. Ran Su explained.

Mu Lingtian touched the wall and asked curiously, "Why does this ice not melt when it is hot?"

"These are Kunlun Xuan Ice, and here is the bottom of Shattered Star Lake, which is enough to make these Xuan Ice not melt for a hundred years. Ran Su said.

"Mother-in-law brought us here, but we want to detoxify Childe?"

Ran Su shook his head and said: "The poison in Mu Shaoxia's body is very domineering, and my internal strength is yin to cold, although it can restrain the toxicity in his body, but it may only be able to remove part of it. If you want to learn my internal skills, it's not that simple. ”

"If your mother-in-law asks for anything, just say it. ”

Ran Su shook his head and smiled: "Mu Shaoxia misunderstood, I don't have any requirements, kung fu is something outside the body, everything I care about in this life has been lost, what else is there to care about." It's just that I said that my internal strength is from yin to cold, so the requirements for the body are also extremely high. So I want to see if Mu Shaoxia can learn it. ”

Mu Lingtian hurriedly bowed his hand and said, "Ling Tian is reckless, please forgive my mother-in-law." ”

"It doesn't matter, I am also entrusted by others to be loyal to others, if you can learn, it is your creation, if you can't learn, it is no wonder to me. Ran Su pointed to the ice pool, and then said to Mu Lingtian: "You need to stay in this ice pool for three days and three nights, and you can only use your internal force to protect your heart, if you can't bear it or have any physical condition, you can come out by yourself, but it also means that you can't practice my internal strength." ”

"Three days in this ice pool!" said Luoxue in surprise and worry.

Ran Su nodded and said, "Yes, three days, you have to guard him for these three days, and if he can't bear it or when something happens, you have to help him get out of the ice pool." ”

Luo Xue looked at Mu Lingtian and nodded, "Well, I understand, thank you mother-in-law." ”

"Don't thank me, let's see if he can survive these three days. Ran Su said to Mu Lingtian again, "Are you ready?"

"Hmm. Mu Lingtian nodded, then put the remnants on the edge of the ice pool, and jumped into the ice pool without any hesitation.

The ice pool was several times colder than here, and the instant coldness was like the feeling of freezing the wind and frost, quickly wrapping Mu Lingtian, and in just a few seconds, Mu Lingtian could already feel that his hands, like ice cubes, were frozen in an instant, and then a stream of coldness, from the soles of his feet to his whole body, spread. It was as if his consciousness and thinking had begun to be slowly frozen, becoming slow, and becoming out of his control, and the coldness could be imagined.

"There is also this room, there are only two keys inside and outside the door, the inside can only be put inside, and the outside can only be put outside, otherwise if you lock yourself in here, even the Da Luo Immortal will not be able to save you. Okay, I'll go out first. After the snow fell from Ran Su's advice, he glanced at Mu Lingtian and turned to leave.

Wrapped in a mink cloak, Luoxue squatted next to the ice pool, poked his hands, sighed, and had some white frost on his eyebrows, and asked, "Childe, you..."

Mu Lingtian looked at Luoxue and said with a faint smile: "I'm fine, you don't have to worry." I can still handle the cold. It's you, it's so cold, or you can go out too, I'm fine, if something really happens, I'll come out by myself. ”

Luo Xue pulled the mink cloak on his body, wrapped himself more tightly, and said with a smile: "It's okay, I can still hold on to the cloak given by my mother-in-law, and my son doesn't have to worry about me." ”

According to what Ran Su said, Mu Lingtian did not use any internal force to resist except for protecting his heart with internal force, and soon Mu Lingtian's whole body was frozen to the point that he was almost unconscious, he could even feel that even the flow of blood became very slow, and the qi of the whole person seemed to be coagulated and frozen, and everything became like ice.

Slowly, Mu Lingtian's whole person seemed to have entered a very wonderful realm, and the inexplicable feeling was indescribable, as if something was very close to him, but it was far away, he wanted to get closer, but he would only get farther and farther away, he wanted to leave, but he was by his side. That kind of subtlety seems to awaken a trace of madness and mania in my heart, I want to struggle, I want to resist, but I want to grasp my floating heart, restless qi, let myself hover between these forces, and my body is constantly repulsed and fused with the cold in the ice pool.

Mu Lingtian began to close his eyes and recuperate, allowing himself to completely integrate into the ice pool, several forces in his body collided with each other to balance each other, and he entered that critical point.

And Luoxue has been silently guarding Mu Lingtian's side, she is very cold, she is firmly wrapped in a mink cloak, her cheeks have been frozen red, and the frost between her eyebrows has already covered those eyebrows, but she stared at Mu Lingtian without blinking, she was afraid that Mu Lingtian would not be able to hold on, she was worried about Mu Lingtian.
