Genshin Impact.

Lin Feng and Li'er, under the guidance of the old man, continued to move forward in the dangerous ruins. The surroundings were filled with an ancient and mysterious atmosphere, and strange runes flashed on the walls.

"The ruins here were left by ancient immortals, and they contain a powerful power of inheritance. But to obtain this inheritance, one must pass many tests." The old man's voice echoed in the empty ruins.

Lin Feng's eyes were determined, and the immortal power in his body surged slightly: "No matter how difficult it is, we must give it a try." Li'er also nodded and followed Lin Feng closely.

They walked along the dark passage, the stone slabs under their feet were engraved with complex patterns. Suddenly, a strong pressure came from the front, and a huge stone door slowly rose up, and a dazzling light shone inside the door.

The three of them stepped into the stone gate, and the scene before them shocked them. A huge martial arts arena appeared before them, surrounded by ancient statues, each of which seemed to contain endless immortal power.

"This is the first test. You need to comprehend a secret of immortality in this martial arts arena." After the old man said this, he stepped aside.

Lin Feng took a deep breath and stepped into the center of the martial arts arena. In an instant, the statues around him seemed to come alive, and beams of immortal power shot towards him. Lin Feng's figure flashed, and he began to fully comprehend the fluctuations of the immortal power around him.

Li Er was not to be outdone. She closed her eyes and tried to feel the mysterious power in this space. As time passed, a faint golden light gradually appeared on Lin Feng's body, and a powerful immortal pattern appeared on his palm.

At the same time, Li'er opened her eyes, and a ball of blue immortal power condensed in her hands. They successfully comprehended the secret of immortality and passed the first test.

Next, they entered a room full of traps. Flames were constantly spurting out from the ground, and sharp spikes popped out from the walls. Lin Feng and Li'er cooperated with each other, using the magic they had just learned, and carefully avoided one trap after another.

At a corner, a huge guardian beast suddenly appeared. It was as big as a mountain, its eyes flashed with fierce light, and it spewed blazing flames from its mouth. Lin Feng was not afraid at all, he flew up with the fairy sword in hand and started a fierce battle with the guardian beast.

Li'er performed magic to support Lin Feng. After a hard fight, the guardian beast fell to the ground under Lin Feng's fatal blow. They continued to move forward and passed the tests of one room after another.

Finally, they arrived at the core area of ​​the ruins. A huge fairy platform appeared before their eyes, on which was placed an ancient scroll, emitting powerful fairy power fluctuations.

"This is a heritage item, and only those who are destined to have it can obtain it." said the old man.

Lin Feng walked up to the immortal platform slowly. When his hand touched the scroll, a strong immortal power surged into his body. His body was enveloped by golden light, and countless immortal secrets and ways of cultivation emerged in his mind.

Li'er looked at Lin Feng, her eyes full of expectation. In the light, Lin Feng's aura continued to rise, and his immortal power was qualitatively improved.

However, at this moment, there was a sudden violent vibration in the ruins. A black crack appeared in the space, and an evil force surged out of it, rushing towards Lin Feng and the others.

"Oh no, the evil power in the ruins has been awakened by the power of inheritance!" The old man's face changed drastically.

Lin Feng opened his eyes, and a trace of determination flashed in his eyes: "No matter what, we must protect this inheritance!"

The three of them stood side by side, fighting against the evil force together. The immortal power and the evil energy collided with each other, and the entire ruins trembled.

In the fierce battle, Lin Feng gradually mastered new immortal skills. He condensed his immortal power into a huge lightsaber and slashed at the evil force. Li'er also exerted her full strength, and her immortal light echoed with Lin Feng's lightsaber.

With their joint efforts, the evil force was gradually suppressed. Finally, with a flash of powerful light, the evil force was completely eliminated.

The ruins returned to peace, and Lin Feng and Li'er smiled at each other. They knew that this journey of inheritance would be an important turning point in their immortal journey.

The old man looked at them and nodded with satisfaction: "From now on, your immortal path will be broader. But remember, the immortal path is long and arduous, and you must not forget your original intention."

Lin Feng and Li'er nodded solemnly. With new strength and mission, they walked out of the ruins and continued on their way to the immortal world in the future...
