Yun Xu had already been scorched by the heat of Neidan at this time, and his mind was a little unclear, and he was reluctantly using his internal force to fight against the heat of Neidan.

He watched in a daze as Mo Yan took out a cloth bag from his arms, this cloth bag looked very familiar to him, and he couldn't remember it for a while. I saw Mo Yan pour out some bits and pieces from the cloth bag, and put them together into the shape of a hand. Yun Xu suddenly realized, a thousand machine hands! Mo Yan wants to use thousands of hands to open this cave wall.

His current physical condition is very bad, his physical strength is seriously overdrawn, and if he uses such a domineering thousand machine hands again, the consequences will be unimaginable.

"Mo Yan, don't!" Yun Xu wanted to stand up to stop him, but his whole body was out of his control, it was sour and numb, and the inside of his bones seemed to be burning.

"It's okay! Don't worry, you'll be fine with me! Mo Yan took Qianji Hand in his hand while comforting Yun Xu.

"You ,......" Yun Xu was worried that something would happen to him, not that something would happen to him, why didn't he understand. Another wave of heat hit, and Yun Xu didn't have a chance to say anything more, so he could only concentrate on confronting Neidan.

Mo Yan looked at Yun Xu, who was struggling on the edge of life and death, and gritted his teeth, how could he not know his thoughts, but he pretended not to know. There are some things he can't afford, and he doesn't want to drag others down.

Retracted his mind, probed the cave wall with his fingers, found the weakest point, and gathered all the strength of his body on his right fist, one punch! Boom! The whole cave was shaken, and the cave wall was cracked with several cracks, and a lot of earth fell, and then the whole picture of the cave wall was clearly seen.

Originally, this place was supposed to be connected to the ice cave, but at some point, the mountain collapsed, and some boulders blocked the entrance of the cave, and the soil gradually blocked the gaps between these boulders over time, forming the current airtight cave wall.

Just now, Mo Yan shook the soil between the boulders, so the boulders were also exposed, and the cold wind in the ice cave also blew in, which was cold and biting.

This was a lot more comfortable for Yun Xu, but it was even more cold and biting for Mo Yan. His teeth chattered, and he shivered with cold. Hurriedly picked up the clothes that Yun Xu had just taken off and put them on himself, because there was only the night pearl illuminated in the cave, so Mo Yan didn't see how heavy the injuries on Yun Xu's body were before, and only when he put on Yun Xu's clothes did he see that there were a lot of blood stains in the clothes, and some of them had dried up. Because the clothes are thicker and have a strong ability to absorb water, there is already a lot of blood inside, but it looks only a shallow one on the outside.

Mo Yan only realized at this time that when Yun Xu flew up to block the ice for him, he was fighting with several swords in his body. I can't help but feel a pain in my heart, but also a warmth, what more can I ask for if I have a friend like this.

Mo Yan was even more determined to open this cave wall, and put on his clothes, although Yun Xu's clothes were much bigger than he wore them, but they were better than nothing, and he felt that his body was warmer a little, Mo Yan was regaining strength, this time he found the most powerful boulder, used all his strength, and punched it, the boulder was moved, and the surrounding boulders also moved, and the entire solid structure was destroyed in an instant, and the entire cave wall composed of boulders suddenly turned into countless boulders and rolled down.

Mo Yan didn't expect that his punch would knock down all these boulders, and he admired it a little when he looked at his right hand!

Immediately, a large cold wind blew in, the wind was very strong, and Mo Yan was about to retreat, he looked at the bottom of the cave against the wind.

This cave is not too high from the bottom of the cave, about a zhang or so, but this cold ice cave surprised Mo Yan too much, there are vertical icicles in it, like mushrooms after a rain, and there are countless holes scattered all over the city.

There are several caves around that blow strong winds inward, which should be the entrance of the earth wind, and the entire cave is shrouded in white cold air, like a fairyland.

"Yunxu! I'll take you in! Mo Yan dragged Yun Xu up hard, pulled him and jumped down together, fortunately, it was not very high, and although the two fell on the ground, it was not very heavy.

Yun Xu obviously felt much better when he entered here, the heat on his body quickly dissipated here, and the red color on his body gradually receded.

Mo Yan helped him to sit down within three icicles in a relatively flat "ice seat", and Yun Xu began to use internal forces to reconcile the heat and cold in his body with the cold in the outside world. Every second is like walking on the tip of a knife, and the slightest carelessness can lead to a madness, or a serious death.

This is the best place for Yun Xu, but for Mo Yan, it is like a cold hell, he is already afraid of cold and cold, and now his body is injured and his blood is insufficient and he does not rest enough, in short, when his body is extremely poor, he is still in this extremely cold place. I felt that my blood was so cold that I couldn't get through, and my body was numb and painful, but I didn't dare to leave, for fear that I would miss it when Yun Xu encountered a key need for help.

I could only grit my teeth and jump beside Yun Xu, running, walking, trying to move as much as possible to keep myself from freezing.

I don't know how long it took, but just when Mo Yan felt that he couldn't hold on, Yun Xu's face suddenly turned purple, and his chest rose and fell faster, as if he couldn't get stuck in one breath.

Mo Yan knew that this was caused by the poor flow of qi and blood, he had suffered internal injuries before, and at that time, Moon Shadow used a silver needle to save his life.

Mo Yan gritted his teeth, there was no moon shadow here, only him, only to do it himself from memory.

Pulled out a silver needle, closed his eyes and recalled, yes, it was Tanzhong acupoint, strength, depth and ......

When he opened his eyes, he pierced with a needle, and while twisting his fingers, he paid attention to Yun Xu's face, which gradually eased and his breathing gradually smoothed.

The silver needle was suddenly pulled out, and Yun Xu also opened his eyes, and spit out a mouthful of black blood with a few ice cubes. He closed his eyes and took a long breath, then exhaled again. When I opened my eyes again, my eyes were a little brighter than usual, and my face was a little whiter than usual, as if I had been reborn, although I was wearing a few blood-stained underwear, I looked a little more fairy.

"You, are you alright?" When Mo Yan saw such a Yun Xu, he knew that not only had his internal injuries healed and the cold qi was expelled, but his internal strength had risen by at least one layer. It seems that this Neidan really has a miraculous effect, and it has not wasted his efforts. I couldn't help but smile with relief.

Yun Xu's mind was clear at this time, and his body was also refreshed like never before, and the internal strength in his body was surging, as if he had inexhaustible strength. He knew that this was the effect of Neidan, and although it was not his intention, he was still grateful to Mo Yan.

"It's okay, I'm fine now!"

"That's good, it didn't hurt you......" Mo Yan's hanging heart finally let go, and the last trace of strength in his body seemed to be drained, and he lost consciousness as soon as it was dark in front of him.
