Rise of the Otherworld.

Lin Yu, exhausted and laden with precious gains, embarked on his journey home. Along the way, he felt both excited and heavy. He was excited because he had successfully defeated the powerful monster and obtained the peerless skills and the mysterious inner elixir; but he was also heavy because the fierce battle had left him severely injured and nearly exhausted.

When he returned to the village, it was already late at night. The villagers had all fallen asleep, and the whole village was immersed in tranquility. Lin Yu tiptoed back to his residence, not caring about treating his wounds, and could not wait to take out the peerless martial arts book, wanting to explore the secrets within.

By the dim candlelight, Lin Yu slowly opened the first page of the technique. The text on it was ancient and obscure, as if it contained endless profound meaning. He frowned and read word by word, trying to understand the meaning.

As time passed, Lin Yu's expression became more and more focused. He found that the cultivation method described in this book was completely different from what he had encountered before. Its concept was profound and subtle, requiring extremely high understanding and perseverance to comprehend.

Unconsciously, the sky outside the window gradually brightened. Lin Yu had not slept all night, but his eyes did not show any fatigue. Instead, they flashed with excitement. After a night of research, he finally had a preliminary understanding of this technique.

However, understanding alone is far from enough. To apply the essence of the exercises to actual practice, you need to keep trying and exploring. Lin Yu took a deep breath, adjusted his breath according to the instructions in the exercises, and began to try to practice.

At first, everything went smoothly. Lin Yu could clearly feel the spiritual energy in his body flowing according to the route of the practice, and his body was gradually filled with strength. But as the practice deepened, problems arose.

A powerful force surged through his body, as if trying to break free from his control. Lin Yu's face turned pale in an instant, and beads of sweat rolled down his forehead. He gritted his teeth and tried desperately to control the force, but to no avail.

"Am I going to fail at the last moment?" A trace of despair flashed through Lin Yu's heart.

At this moment, the system's voice sounded: "Host, remain calm and try to guide this power to gather in the Dantian."

When Lin Yu heard the system's prompt, it was like seeing a ray of light in the darkness. He endured the severe pain and followed the system's instructions, trying to guide the out-of-control power.

After some hard work, the power was finally tamed and gathered in the Dantian. Lin Yu breathed a sigh of relief and collapsed to the ground.

After this setback, Lin Yu did not dare to practice rashly, but calmed down and carefully summed up the experience and lessons. He found that practicing this peerless skill required extreme caution, and the slightest carelessness could lead to obsession.

In the days that followed, Lin Yu continued to study the technique while recovering from his injuries. He constantly adjusted his training methods, and was cautious in every attempt.

Finally, after many failures and setbacks, Lin Yu gradually mastered the essentials of cultivation. His strength was also greatly improved without him realizing it.

At the same time, Lin Yu did not forget the inner elixir he got from the monster. By consulting ancient books and asking experts, he learned that this inner elixir contained powerful energy, which would be of great benefit to his cultivation if it could be absorbed properly.

But the energy in the inner elixir is too violent. If absorbed directly, it is likely to cause serious damage to the body. Lin Yu fell into deep thought, thinking about how to safely absorb the energy in the inner elixir.
