Autobiography of Li Yunfei, a time traveler

The powerful force suddenly pushed Li Yunfei and the other two back several steps. They steadied themselves and looked at the mysterious formation in front of them with shock on their faces.

"The power of this formation is so strong!" Ye Ying said, covering his chest.

Li Yunfei frowned, "It seems that this formation is not simple, we have to deal with it carefully."

Lin Ya nodded, "Let's observe and see if we can find a way to crack it."

They walked slowly around the formation, carefully observing every detail of the formation. The formation was engraved with complex runes and lines, flashing with strange light, as if it contained endless mysteries.

After some observation, Li Yunfei found that the formation seemed to have some subtle connection with the surrounding environment. "I think this formation may rely on the surrounding energy to operate." He said thoughtfully.

Yeying's eyes lit up, "What if we cut off its energy source?"

Lin Ya thought for a moment and said, "This is a solution, but we have to find a channel to transfer energy first."

So, they began to look for possible energy transmission channels in the palace. After some efforts, they finally found some hidden lines on the walls of the palace, which seemed to be the energy transmission paths.

Li Yunfei looked at the lines and said, "Let's look along these lines, maybe we can find the key."

They followed the lines and finally found a huge crystal in a corner of the palace. The crystal was emitting strong energy fluctuations, which was obviously the energy core of the formation.

"That's it!" Li Yunfei said excitedly.

They approached the crystal cautiously, but just as they were about to touch it, the crystal suddenly emitted a dazzling light, followed by a powerful force sweeping towards them.

Li Yunfei and the other two hurriedly used their skills to dodge, but the force was so fast that it still hit them. They were knocked out and fell heavily to the ground.

"Cough cough..." Li Yunfei coughed up a mouthful of blood and struggled to get up.

Ye Ying and Lin Ya were also injured, but they still stood up firmly.

"We can't give up, we will definitely be able to break this formation!" Lin Ya said firmly.

They rushed towards the crystal again, this time they were more cautious. Li Yunfei used his sword skills, and sword energy flew towards the crystal, trying to weaken the power of the crystal. Ye Ying assisted from the side, using his sword to resist the attack released by the crystal.

Lin Ya concentrated her energy on finding the flaws in the crystal. After a fierce battle, Lin Ya finally found a weakness in the crystal.

"Li Yunfei, attack there!" Lin Ya shouted loudly.

Upon hearing this, Li Yunfei immediately concentrated all his strength on one sword and stabbed in the direction Lin Ya pointed.

With a "crack" sound, a crack appeared on the crystal. The light of the crystal began to flicker, and the power of the formation weakened.

"It works! Keep attacking!" Yeying shouted excitedly.

The three of them launched an attack again, continuously attacking the weak points of the crystal. Finally, the crystal was completely shattered under their attack, and the formation stopped working instantly.

"Success!" Li Yunfei shouted excitedly.

However, before they could celebrate, the palace suddenly began to shake violently.

"Oh no, this palace is going to collapse!" Ye Ying's face changed drastically.

Li Yunfei hurriedly shouted: "Go!"

The three of them quickly ran out of the palace, and just as they ran out of the palace, the palace collapsed with a loud bang, raising a cloud of dust.

They stood in the distance, looking at the collapsed palace, their hearts filled with emotion.

"Where are we going next?" Yeying asked.

Li Yunfei thought for a moment and said, "Let's continue to explore this holy land and see if there are any other secrets and challenges."

Lin Ya nodded in agreement, "Okay, let's go."

The three of them set out on an adventure again, continuing to explore unknown areas in the Holy Land...
