Du Chunxiao turned his back and left, only to feel that one of his hearts was pounding, and he didn't dare to look there.

The old man turned around, and then whispered to her: "This 10,000-year-old ice water in the Heavenly Immortal Pool, my skills are not weak, but I only have to stay here for half an hour at a time, this person is highly poisonous, at least I have to rely on this extremely cold ice water to soak for three days and three nights, in order to force out all the poison in my heart."

But whether he can withstand the extreme heat of his body and the extreme cold of this water, I can't imagine.

As a teacher, he is known as a medical saint, even if he can rejuvenate himself, he can only go so far. In the future, if the manpower is weak, he can only rely on this person's own survival**! We don't have to worry about him, and we can't care about it anymore. ”

When the old man had said this, he turned and left.

Du Chunxiao looked at Liu Yuxuan, whose eyes were closed and his face was already starting to turn blue, feeling uneasy in his heart, and whispered to himself: "Why do you want to block that deadly secret weapon?" Even if the lives of the people are innocent, how can your life not be precious? ”

Thinking so in her heart, she gritted her teeth, turned around and left quickly, bidding farewell to the old man and hurried back to the Youzhou Mansion.

The sky gradually changed, and it was already a cold wind, rolling up endless yellow sand, disturbing the sky and the earth dark and colorless.

The outside of the Tianxian Pond is dim, but the inside of the cave is shining, and it is the result of the stone wall in this cave, which is full of strange insects that inhabit here, and the body is constantly glowing like fireflies.

Half an hour later, Liu Yuxuan gradually felt a biting coldness on his body, constantly piercing into the bone marrow.

He snorted in pain, then opened his eyes slightly, looked around, and was disturbed in his head, and for a moment, he didn't know why he was here, and where he was.

Another biting cold invaded his limbs, and he suddenly came to his senses, trembling and looking around, and exclaimed in surprise, and was about to stand up, but he felt that his limbs were weak and weak, and with a little exertion, he felt even more cold to his bones, and he cried out in pain.

He vaguely remembered the hidden weapon in his body, falling down from the high platform, it seemed that someone below blocked the falling path with his body, but after that, it was all blank, and there was no memory anymore.

"Who saved me? Where am I now? ”

He thought about it desperately, and a big red figure flashed in his mind, but suddenly, he felt a sharp pain in his limbs, and he reached out and clung to the edge of the pool, trying to control the pain that kept incurring.

Who knows, as soon as he resisted the strange cold around his body, a stream of heat immediately poured out of his body, dispelling the cold around him.

When Liu Yuxuan was feeling comfortable with his body, the heat increased sharply, and he continued to swim around his body, gradually forcing all the cold air away, and replacing it with bursts of scorching heat, like a flame spewing out, wrapping him tightly, as if he was in molten lava, burning him in pain, and he didn't feel muffled.

He couldn't bear it anymore, so he hurriedly inhaled and dissipated the internal force in his body, and then gradually felt that the heat in his body had decreased a lot.

But it was only an instant, and when the burning sensation on his body disappeared, the cold feeling slowly recovered, and he was immediately thrown into the extremely cold ice cave.

But after some experience, he still understood that at this time, whether he was facing the scorching heat or the extreme cold, he could never resist with luck, and he could only let the heat of his body and the cold in this pool fight against each other, and he could only become the object of torture by the intertwining of these two extreme pains.

Liu Yuxuan was like this, repeatedly experiencing the constant burning and cold, and he gritted his teeth in pain and couldn't bear these two extreme tortures, and couldn't help but shout.

"What's wrong with me? Why is it so painful to be cold and hot for a while? ”

His cry of pain echoed in the empty Tianxian Pool, startling the insects on the cave wall and flying in all directions, hula and lala all flapped their wings and flew to the Tianxian Pool, circling around the surface of the water.

At this time, by chance, one or two insects flew to the pool where Liu Yuxuan was lying, touched Liu Yuxuan's head, and immediately turned into puffs of smoke, and he was burned alive by the heat on his body.

These insects had just turned into flying smoke, and the countless insects that were constantly circling over there, seeing that their kind had disappeared, they were immediately extremely angry, buzzing and making a noisy sound, and then they all turned their heads and came straight to Liu Yuxuan, obviously wanting to avenge their companions.

Liu Yuxuan was shocked to see that countless glowing insects surrounded his head, rushing towards his head desperately, and they all immediately turned into clouds of smoke and dissipated.

But when the rest of the insects saw this, not only did they not retreat timidly, but they flapped their wings and came at them one after another.

Countless insects were wiped out, but the burning sensation on his body suddenly eased somewhat.

In an instant, the countless cute insects turned into clouds of smoke and disappeared, and the burning heat on Liu Yuxuan's body gradually dissipated, and the cold feeling around him became more and more intense.

After more than two hours, the cave walls were already dark, but most of the insects had died and disappeared.

Seeing this, the remaining thousands of insects had to turn around, flutter their wings and return to the cave wall, and they actually overlapped each other and began to mate.

In less than half an hour, the females flew to a cold place and began to lay eggs in the water.

The eggs of these insects were also slightly fluorescent, and immediately the water on the Tianxian Pond was shining, and the blue was very charming.

After another half an hour, the eggs began to change, and countless small insects that had formed struggled out of the water, and immediately spread their wings when they touched the air, and then they grew up a lot, and immediately shook their wings and flew to the cave wall, and began to mate in pairs and lay eggs.

After just over an hour, the walls of the cave around the Heavenly Immortal Pond were fluorescent again, and there began to be a little bit of light.

When Liu Yuxuan saw this, he was already amazed, and he felt incredible, so he tried to move his body in the water, but he no longer had the feeling of hot and cold, he simply felt the cold in this pool.

Liu Yuxuan could no longer bear the cold breath in the pool of water, and stood up from the water with a shout, but his body was already full of strength, and he didn't seem to feel any discomfort anymore.

He pulled his feet out of the pool, **naked** standing on the edge of the Tianxian Pool, only felt extremely cold, and did not feel secretly lucky to adjust the cold around him, but there was no abnormality, so he simply found a smooth stone and sat down, sat down cross-legged, and began to concentrate on luck.

Gradually, he felt that the cold around him was no longer as unbearable as it had been.

"It's strange that these little worms have played such a big role, trading their own lives for your life! You're so endless! ”

Suddenly, in the silence of the cave wall, there was a sound of surprise.

Liu Yuxuan hurriedly got up and went along with the voice, but suddenly saw a person standing at the entrance of the cave, covered in a big red robe, with a red turban on his head, and he couldn't see what his body looked like at all, and a name came to his mind: "Du Chunxiao!" ”

The red figure trembled clearly, and stood silently for a long time before turning to leave.

"Don't go! I ......"

When Liu Yuxuan saw that she was about to leave, he was anxious and shouted at her, but unexpectedly, a scorching breath suddenly gushed out from his body, swallowing him up and drowning him in an instant.

He fell to the ground in pain, only to feel that he was about to be scorched and suffocated by the scorching flames of the underworld again. At this time, suddenly a red figure flashed in front of him, he had been picked up by Du Chunxiao vigorously, walked quickly to the pool, was carefully put into the water, and lay down again against the pool.

Liu Yuxuan didn't have time to react, Fang Cai's torture of his life and death was not as good as the two heavens of water and fire, and it was again and again, and he began to torture himself fiercely.

He bit his lips in pain, and a little bright red dripped from his mouth, dripping into the water, staining it crimson.

Du Chunxiao was caught off guard, looking at Liu Yuxuan, who was screaming in pain in the pool, he only felt that he also felt the same way, and the pain in his heart was unbearable, and he was already in tears unconsciously.

"Ah, what's wrong with me? Why did I return here in a hurry after only half an hour, and I was so worried about him that it was difficult to feel at ease, so I hurriedly returned here? Seeing him in pain, I felt the same way, but it was really the first time in my life! What's wrong with me? Is it ......?"

Du Chunxiao didn't dare to think about it anymore, seeing that he was already in pain and was about to faint, and was about to reach out to point his acupoint to stop the pain around him, but suddenly he heard the sound of wings flapping in his ears, and hurriedly raised his eyes to look, but saw that the small insect on the wall of the cave was buzzing and screaming desperately, and flew towards Liu Yuxuan.

In an instant, the top of Liu Yuxuan's head was covered in a dense air.

Du Chunxiao was dumbfounded, so he had to take a few steps back, seeing that as soon as countless small insects touched Liu Yuxuan's head and body, they immediately turned into clouds of smoke and disappeared.

Du Chunxiao hurriedly hurried a few steps over, leaned over to look at Liu Yuxuan in the pool, but was pleasantly surprised to see that his manic pain had completely disappeared, and his hot face had begun to turn white, knowing that the burning sensation in his body at this time had been temporarily dissipated, and the cold qi in the water had prevailed again, so he hurriedly reached out and helped him out of the pool and sat on the stone.

"You...... Get lucky! Beware of the cold invading your heart and lungs! ”

She suddenly saw that Liu Yuxuan in front of her turned out to be naked, and she was in a panic, just thinking about saving him, but she didn't pay attention at all, but at this time, she was looked at by herself, and she didn't wake up, her heart beat violently, and she hurriedly turned around with a blushing face, and reminded him loudly.
