Rise of the Otherworld.

Lin Yu and Lin Xiaotian continued to walk towards the depths of the Death Valley, carefully avoiding various dangerous traps and monsters.

Finally, they came to a mysterious ruin. This ruin looked very ancient, and the walls were engraved with various mysterious runes and patterns.

"This relic looks very unusual, we need to be careful," said Lin Xiaotian.

Lin Yu nodded. He also felt that this relic was unusual. So they slowly walked into the ruins.

The ruins were very quiet, with only the sound of their footsteps echoing. Suddenly, a ray of light shot over from the front, and Lin Yu and Lin Xiaotian hurriedly stopped.

"What is this?" Lin Yu asked.

Lin Xiaotian frowned and observed the light carefully. Suddenly, his expression became serious.

"This is a seal. It seems that there is something important hidden in this relic." Lin Xiaotian said.

Lin Yu nodded. He also felt the power of this seal. So, they began to look for a way to break the seal.

After some effort, they finally found a way to break the seal. Lin Yu used his unique skills, and a long sword appeared in his hand and stabbed towards the seal.

The seal emitted a ray of light, blocking Lin Yu's sword. Lin Xiaotian also displayed his unique skills. A huge axe appeared in his hand and chopped towards the seal.

The seal emitted a ray of light again, blocking Lin Xiaotian's giant axe. Lin Yu and Lin Xiaotian looked at each other. They knew that this seal was not something they could easily break.

"We must find a more powerful force to break this seal." Lin Xiaotian said.

Lin Yu nodded. He also knew Lin Xiaotian's thoughts. So, they began to look for a more powerful force in the ruins.

After searching for a while, they finally found a mysterious treasure chest. The treasure chest was engraved with various mysterious runes and patterns, and it looked very precious.

"There must be something important in this treasure chest." Lin Yu said.

Lin Xiaotian nodded. He also felt that this treasure chest was unusual. So, they opened the treasure chest carefully.

Inside the treasure chest was an ancient book engraved with various mysterious runes and patterns. Lin Yu and Lin Xiaotian carefully observed the book and found that it contained a powerful power.

"This is a powerful force. We must learn it before we can break the seal." Lin Xiaotian said.

Lin Yu nodded. He also knew Lin Xiaotian's thoughts. So, they began to learn this powerful power.

After some effort, they finally learned this powerful power. Lin Yu exerted this power, and a ray of light appeared in his hand and shot towards the seal.

The seal emitted a ray of light, blocking Lin Yu's light. Lin Xiaotian also exerted this power. A ray of light appeared in his hand and shot towards the seal.

The seal emitted a ray of light again, blocking Lin Xiaotian's light. Lin Yu and Lin Xiaotian looked at each other. They knew that this seal was not something they could easily break.

"We must use this power together to break the seal." Lin Xiaotian said.

Lin Yu nodded. He also knew Lin Xiaotian's thoughts. So, they exerted this power together. A ray of light appeared in their hands and shot towards the seal.

The seal emitted a ray of light, blocking the light of Lin Yu and Lin Xiaotian. However, this time the light of the seal became much dimmer.

Lin Yu and Lin Xiaotian used this power again. A ray of light appeared in their hands and shot towards the seal.

This time, the seal was finally broken. A ray of light shot out from the seal, illuminating the entire ruins.

Lin Yu and Lin Xiaotian walked into the seal and found a huge treasure inside. The treasure was filled with various precious items, including weapons, magic weapons, pills, and so on.

"The things here are very precious, we must make good use of them." Lin Xiaotian said.

Lin Yu nodded. He also knew the value of these things. So, they began to collect these precious items.

After some effort, they finally collected all the precious items. They left the ruins with these items and headed towards the exit of Death Valley.
