Rise of the Otherworld.

After communicating with the mysterious old man, Lin Yu became more determined to follow his path of cultivation. He knew that in order to become a truly strong person, he must constantly challenge himself and break through his limits.

In the following days, Lin Yu continued to explore every corner of the ancient Xuan Continent, encountered many powerful monsters and mysterious relics, and also made many like-minded friends.

During an expedition, Lin Yu accidentally discovered a mysterious relic hidden in a deep mountain, surrounded by a mysterious atmosphere.

Lin Yu's heart moved. He felt that this relic contained a powerful force. He decided to enter the relic and explore it to see if he could find some opportunities to improve his strength.

After entering the ruins, Lin Yu found that it was full of ancient buildings and mysterious runes. He carefully explored every corner, fearing that he would miss any important clues.

Deep in the ruins, Lin Yu discovered a huge stone door. The stone door was engraved with complex runes and exuded a powerful aura.

Lin Yu's heart was shocked. He knew that there must be something important hidden behind this stone door. He took a deep breath, used all his strength, and slowly pushed the stone door open.

After the stone gate opened, a powerful breath rushed in. Lin Yu looked closely and saw that behind the stone gate was a huge square with an ancient palace standing on the square.

The gate of the palace was closed, and it was engraved with mysterious runes. Lin Yu's heart moved, and he felt that this palace contained a powerful power.

He approached the palace cautiously, stretched out his hand and gently pushed the door. The door slowly opened, and a strong breath rushed towards him.

Lin Yu looked carefully and saw many precious magic weapons and mysterious skills placed in the palace. He was delighted, knowing that he had really picked up a treasure this time.

He couldn't wait to walk into the palace and began to select the magic weapons and skills he needed. In the corner of the palace, Lin Yu found an ancient scroll.

The scroll was engraved with mysterious runes, emitting a powerful aura. Lin Yu's heart moved, and he felt that the scroll contained a powerful power.

He carefully picked up the scroll and opened the first page. There were four large characters written on it: "Chaos Sutra".

Lin Yu's heart was shocked. He knew that he had really picked up a treasure this time. This Chaos Sutra was an extremely profound practice method. It was said that after mastering it, one could control the power of chaos and have the ability to destroy the world.

Lin Yu took a deep breath and began to study the Chaos Sutra seriously. He found that the Chaos Sutra contained many profound principles and powerful powers, which required him to constantly explore and comprehend.

In the following days, Lin Yu locked himself in the palace and devoted himself to studying the Chaos Sutra. He continued to practice and comprehend, and his strength continued to improve.

After a period of practice, Lin Yu finally cultivated the Chaos Sutra to the Great Perfection Realm. His strength was greatly improved, surpassing many powerful people on the Ancient Xuan Continent.

Lin Yu decided to leave the ruins and return to the True King Sect. He wanted to pass on what he had learned to the disciples of the True King Sect so that they could also become strong.

Before leaving the ruins, Lin Yu left his legacy in the palace. He hoped that one day, a destined person would come here, inherit his legacy, and become a truly powerful person.

Lin Yu left the ruins and embarked on the journey back to the True King Sect. He knew that his future was full of challenges and opportunities, and he had to work hard to achieve his goals.
