Autobiography of Li Yunfei, a time traveler

Li Yunfei and his companions had a fierce battle with the mysterious black shadow. The black shadow was extremely fast, shuttling among the crowd like a ghost, making it difficult to catch its figure.

"Everyone be careful!" Li Yunfei shouted loudly, and at the same time used his unique skills, and sharp sword energy attacked the black shadow.

The black shadow easily avoided Li Yunfei's sword energy, and slapped out a powerful palm force with his backhand, directly knocking Li Yunfei back several steps.

Seeing this, Lin Ya quickly waved the staff in her hand and released a series of magic attacks. The shining magic balls hit the black shadow like meteors, but the black shadow just waved his hand lightly and all the magic balls were dissipated.

Ye Ying relied on his agility to constantly look for Black Shadow's flaws, trying to give him a fatal blow. However, Black Shadow's defense was extremely tight, so Ye Ying could never succeed.

"Damn, this guy is so difficult to deal with!" someone couldn't help but complain.

"Don't panic, if we work together, we will definitely be able to defeat him!" Li Yunfei encouraged everyone.

Everyone gathered their spirits and attacked the black shadow with all their strength. They each used their strongest moves, and for a moment, light shone and energy overflowed.

Under the siege of the crowd, the black shadow gradually felt the pressure. He roared, and the aura on his body surged again. A black mist surged from his body and quickly spread.

"Oh no! This fog is poisonous!" someone shouted.

Everyone hurriedly used their spiritual power to resist the erosion of the poisonous gas. However, the poisonous gas was very strong and many people still felt dizzy.

Li Yunfei was extremely anxious. He knew that he couldn't drag it on any longer and had to find the shadow's weakness as soon as possible. He concentrated his energy and carefully observed the shadow's every move.

Suddenly, he discovered that the shadow would pause briefly every time it attacked. Although this pause was extremely subtle, it was still captured by Li Yunfei.

"Now!" Li Yunfei shouted, and with a flash of his body, he rushed towards the black shadow.

At the moment when the black shadow attacked, Li Yunfei seized the opportunity of pause and stabbed the black shadow in the chest with a sword. The black shadow was shocked and it was too late to dodge. He could only watch Li Yunfei's sword pierce his body.

"Ah!" The black shadow let out a scream, and his breath quickly weakened.

Seeing this, everyone took the opportunity to attack. Under the combined siege of everyone, the black shadow finally couldn't hold on and fell to the ground.

However, before everyone could breathe a sigh of relief, the shadow's body suddenly began to change. His body gradually dissipated, turning into a ball of black mist, and then quickly merged into the surrounding air.

"Oh no, he's not dead yet!" Li Yunfei shouted.

Sure enough, the black mist condensed into a black shadow again and appeared in front of everyone.

"Hahahaha, do you think you can kill me like this? Too naive!" The black shadow sneered.

Li Yunfei and the others looked solemn. They did not expect that this black shadow would be so difficult to deal with.

"Don't be afraid, we will definitely find a way to defeat him!" said Li Yunfei.

They fought with the black shadow again, and this time, they were more cautious and kept looking for the black shadow's flaws.

After a tough battle, they finally discovered a fatal weakness of Black Shadow. Every time Black Shadow launched a powerful attack, there would be a short period of energy gathering, and during this process, his defense would become very weak.

Li Yunfei and others seized this opportunity and began to attack the black shadow in a targeted manner. Whenever the black shadow was about to launch a powerful attack, they would concentrate their firepower on his weaknesses.

Under the attack of everyone, the black shadow gradually fell into trouble. His breath became weaker and weaker, and finally he could not hold on any longer and completely dissipated into the air.

"We finally defeated him!" everyone cheered.

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

"Oh no! The ruins are going to collapse!" someone shouted.

Li Yunfei and others hurriedly ran towards the exit of the ruins. During the escape, huge rocks kept rolling down, causing them a lot of trouble.

But with their tenacious will and agility, they finally managed to escape from the ruins.

When they walked out of the ruins and looked back, they saw that the ancient ruins had completely collapsed due to the shaking.

"This adventure was so thrilling." Lin Ya said with emotion.

"Yes, but we also gained a lot." Li Yunfei said as he looked at the secret book and artifact in his hand.

After a short rest, they set out on their return journey. They knew that there were more challenges and opportunities waiting for them...
