Leng Xuan found that he was in a cave. The cave was not big, about ten meters in diameter, with hard stone walls on all sides, with fiery red, and a hint of heat coming out of it. The ground was covered with cracks, and the flames erupted from it before. Leng Xuan walked to the stone wall, reached out to knock, and then moved to another place to try to find a way to escape. Seeing this, Hongwu said, "Boy, don't waste your energy. If you can go out, why should I waste thirteen years here? I advise you to save some energy, the flames under the ground will erupt soon."

Leng Xuan heard this, but was unmoved and still searched the cave seriously. However, more than ten minutes passed, as Hongwu said, he found nothing. The cave was like a barrier, without any flaws. He shook his head helplessly, and then sat cross-legged on the ground. At this time, he suddenly remembered the slurry he saw when he came in before, and couldn't help asking: "Senior, is this slurry built in a volcano?" Hongwu closed his eyes slightly and said calmly: "No." Leng Xuan said strangely: "How is the slurry here formed?" Hongwu snorted softly: "You ask me, who am I going to ask? Okay, don't disturb me anymore."

Seeing that he refused to pay attention to him, Leng Xuan couldn't help but smile bitterly. At this time, he felt the ground getting hotter and hotter, and a stream of hot air gushing out of the cracks. Obviously, the flame was about to erupt again. He took a deep breath, then closed his eyes, held his breath and calmly waited for the impact of the flames. If he could use the Nine Yangs God Forging Technique to resist the invasion of the flames, but now the Dantian and meridians are sealed and he cannot use the exercises at all.

When the flames erupted from the crack, Leng Xuan suddenly felt a piercing pain coming through his skin. Although he was mentally prepared, the severe pain was still unbearable. He opened his eyes and glanced at Hongwu not far away. He saw the other person sitting cross-legged on the ground, looking calm, as if the surging flame had no effect on him.

Leng Xuan took a few deep breaths and forcibly endured the pain that seemed to have penetrated into the depths of his soul. But after enduring it, he couldn't help but wail. At this time, his mind was already a little confused. A sense of self-protection was running rapidly in his mind without being controlled. Then, deep in the dantian, there was a trace of true energy that was so weak that it could be ignored that it broke through the restraint and slowly moved into his body.

Feeling the operation of this true qi, Leng Xuan was surprised to find that the operation route of the faint true qi was actually the operation route when practicing the Nine Yang God Forging Art, which surprised and happy. Due to his confusion in consciousness, in order to concentrate his attention, he couldn't help but murmuring the mantra of the Nine Yang God Forging Art.

Suddenly, Hongwu, who had been sitting in peace with his eyes closed, opened his eyes and looked at Leng Xuan with a little surprise, his eyes full of confusion.

Time passed by little by little. Under the pain, Leng Xuan felt that his consciousness gradually became blurred and he was already facing the verge of collapse. At this moment, a "其" scream suddenly came from his ears. Although the sound was small, it exploded in his ears like thunder, making his drowsy consciousness wake up instantly. At the same time, Hongwu's voice came: "Boy, hold on, there is still one minute."
