Genshin Impact.

Lin Feng followed Amber into Mondstadt. The city had a unique architectural style and was full of a free and romantic atmosphere. The streets were bustling with people and their faces were filled with smiles.

Amber brought Lin Feng to the headquarters of the Knights of Favonius and introduced this new friend from another world to everyone. The members of the Knights welcomed Lin Feng's arrival and were curious about his life experience and the reason for his appearance in Teyvat.

In the Knights, Lin Feng met important figures such as Acting Leader Qin, Librarian Lisa, and Cavalry Captain Kaia. Qin told Lin Feng that in Teyvat, if one wants to master elemental power and achieve success in the path of cultivation, one must go through continuous learning and trials.

In order to help Lin Feng understand and master the elemental force, Qin arranged for him to receive basic elemental force training in the Knights. As a magician of the Knights, Lisa was responsible for teaching Feng Feng the theoretical knowledge of elemental force.

"Elemental force is the basic power of the continent of Teyvat. It is divided into seven basic elements: fire, water, wind, thunder, ice, rock, and grass. Each element has its own unique characteristics and abilities." Lisa sat at the desk in the library, patiently explaining to Lin Feng.

Lin Feng listened carefully and asked some questions from time to time, and Lisa answered them one by one. After a few days of theoretical study, Lin Feng had a preliminary understanding of elemental power.

Next, it was practical training. Kaiya was responsible for guiding Lin Feng in the practical application of elemental power. They came to a training ground outside the city, and Kaiya took out a wooden sword for training and handed it to Lin Feng.

"First, you must try to feel the elemental force in your body, and then channel it into the sword," Kaeya said.

Lin Feng held the wooden sword, closed his eyes, and tried to feel the strange power in his body. With his concentration, he gradually felt a trace of warm power flowing out from deep inside his body, slowly gathering on the wooden sword in his hand.

A faint flame flickered on the wooden sword, and Lin Feng opened his eyes excitedly.

"That's a good start, but it's far from enough." Kaia said with a smile, "Next, try to use this power to attack the target."

Kaiya set up some scarecrows on the training ground as targets. Lin Feng took a deep breath, raised the wooden sword burning with fire in his hand, and chopped at the scarecrows. The flames instantly spread to the scarecrows and ignited them.

"Very good, but the use of elemental power is not just about attack, it also includes defense, control and other aspects." Kaeya said as he demonstrated it himself.

Under Kaia's guidance, Lin Feng continued to practice various techniques for using elemental power. After a period of hard training, his use of elemental power has made great progress.

However, the real challenge has just begun. Qin told Lin Feng that in order to test the results of his training during this period, he needs to participate in an elemental trial. This trial will be held in a mysterious ruins in the Whispering Forest.

On the day of the trial, Lin Feng came to the entrance of the ruins accompanied by members of the Knights. Qin encouraged him, "Lin Feng, believe in your efforts during this period, you will definitely be able to pass the trial."

Lin Feng nodded, took a deep breath, and walked into the ruins. The ruins were filled with an ancient atmosphere, and mysterious runes flickered on the walls.

Lin Feng walked forward cautiously, and suddenly, a group of elemental monsters rushed out from the shadows. There were flame slimes, ice mist flowers, lightning firefly warlocks, etc. They attacked Lin Feng.

Lin Feng quickly raised his wooden sword and used the power of fire to fight back. The flames burned fiercely on the sword, and he swung the sword, and a stream of flaming sword energy shot towards the monsters. The monsters were hit by the flames and retreated one after another.

But the monsters did not give up the attack, they kept changing their attack methods. Lin Feng flexibly used the elemental force skills he had learned and started a fierce battle with the monsters.

During the battle, Lin Feng discovered that there seemed to be some kind of elemental resonance between these monsters. If he could cleverly utilize this, he would be able to defeat them more easily.

He began to try to guide the interaction between different elemental forces. When the flames met the ice mist flowers, a steam explosion would occur, causing damage to the surrounding monsters; when the lightning elemental force hit the water surface, a conductive effect would be produced, paralyzing nearby monsters.

Relying on his wisdom and courage, Lin Feng gradually mastered the rhythm of the battle and defeated the monsters one after another.

After a hard battle, Lin Feng finally came to the depths of the ruins. Here, he found a huge elemental core. The core was surrounded by powerful elemental energy. If it was not properly handled, once this energy exploded, it would cause a huge disaster.

Lin Feng knew that this was the last stage of the trial. He calmed down, recalled the knowledge of elemental power he had learned, and began to try to control and absorb the elemental energy.

He slowly injected his elemental force into the core, communicating and integrating with the energy in the core. At first, the energy in the core resisted his power, but Feng Feng did not give up and kept adjusting his elemental force output.

Finally, the energy in the core began to stabilize and was slowly absorbed by Feng Feng. When the last bit of energy was absorbed, a dazzling light flashed in the ruins.

The trial was successful!

Lin Feng walked out of the ruins, and the members of the Knights were waiting for him at the entrance. Seeing him return safely, everyone cheered.

Qin walked forward, patted Lin Feng on the shoulder, and said: "Congratulations, Lin Feng, you have successfully passed the trial. From now on, you have taken an important step in mastering elemental power."

Lin Feng wiped the sweat from his forehead and smiled happily. He knew that his journey to becoming an immortal in Teyvat had just begun, and there were more challenges and opportunities waiting for him...
