Genshin Impact.

After learning part of the truth, Lin Feng and Li Er's sense of mission became stronger. They knew that the road ahead was full of thorns, but for the sake of the people of the world and to explore the ultimate truth, they had no way out.

The old man looked at the two people's determined eyes, his heart full of relief and worry. He knew that the two children had decided to go on, and no matter how difficult and dangerous the road ahead was, they would not back down. But he also understood that the road ahead would be more rugged, full of unknowns and dangers. "Children, the road ahead will be more difficult, you must be prepared." The old man's voice was solemn.

Lin Feng clenched his fists tightly, with a determined light in his eyes: "Don't worry, senior, we will do our best." Li'er also nodded in agreement: "No matter what we encounter, we will not back down." There was a determination in her eyes, as if she was ready to face all difficulties.

In the following days, the three began to prepare for the upcoming war. Lin Feng practiced day and night, constantly honing his immortal skills, striving to use every spell to the extreme. He was immersed in the world of practice, forgetting the passage of time, and devoted himself to the process of improving his strength. Li'er focused on improving her spiritual perception ability, and tried to break through her limits through meditation and perception. She hoped to be able to see the enemy's movements in advance in the battle, so as to better deal with various situations.

The old man silently observed the progress of the two, giving some guidance and advice from time to time. He felt extremely relieved as he watched their increasingly powerful auras. He knew that the two children were gradually growing into real strong men, capable of facing future challenges. However, he also clearly realized that the scale and complexity of this war far exceeded their imagination. They not only needed strong strength, but also wisdom, courage and teamwork.

During the intense preparation period, Lin Feng and Li Er did not forget the emotional exchange between each other. They often discussed their training experiences together, encouraged and supported each other. In this process, their feelings became deeper and they became each other's most important support. Although the future is full of uncertainty, they believe that as long as they work together, they will be able to overcome all difficulties.

As time goes by, Lin Feng and Li Er finally face a major test in their lives. A thrilling battle is about to begin, and they must face an unprecedentedly powerful enemy and use their own strength to protect the people of the world.

The old man was not idle either. He relied on his many years of experience and profound knowledge to develop a detailed strategic plan for the two. At the same time, he also ran around to collect various intelligence and understand the enemy's weaknesses.

In his spare time, Lin Feng often stood alone on the top of the mountain, quietly looking into the distance, his heart filled with endless thoughts. He knew that the upcoming battle was not only related to the fate of himself and Li'er, but also determined the future direction of the entire world. Li'er keenly sensed Lin Feng's inner worries. She silently walked to Lin Feng's side, gently placed her hand on his shoulder, and gave him silent support and encouragement.

"Lin Feng, no matter what awaits us ahead, I will fight alongside you without hesitation." Li'er's voice was as gentle and firm as the spring breeze.

Lin Feng turned around and held Li'er's hand tightly, his eyes gleaming with affection: "Li'er, as long as you are by my side, I will have nothing to fear."

As time went by, the atmosphere of the war became more intense, and the whole world seemed to be shrouded in a tense atmosphere. People felt heavy-hearted, as if they could sense the coming storm. However, Lin Feng, Li Er, and the mysterious old man had already made full preparations, and they quietly waited for the moment of the decisive battle.

At this critical moment, everyone knows that this battle will be a life-and-death contest. But they firmly believe that as long as they unite as one, they will be able to defeat the dark forces and protect this beautiful world.
