Autobiography of Li Yunfei, a time traveler

The vibrations in the ruins became stronger and stronger, as if the entire space was about to collapse. Li Yunfei and Lin Ya looked around vigilantly, their hearts filled with tension and anxiety.

Suddenly, a huge black shadow slowly walked out from the depths of the ruins. When the black shadow appeared in front of them, they both gasped. This was a giant beast that was several times larger than the previous monsters. It had a ferocious head, blood-red eyes that emitted a terrifying light, sharp fangs like giant swords, and thick limbs that seemed to be able to crush the earth easily.

"What...what kind of monster is this?" Lin Ya asked with a trembling voice.

Li Yunfei's face was solemn. "No matter what it is, we must fight to the end."

After that, Li Yunfei mobilized the spiritual power in his body again, and with a flash of his body, he took the initiative to rush towards the giant beast. He used his strongest boxing skills, and the shadow of his fist attacked the giant beast like a storm.

However, the strength of the beast was far beyond their imagination. It waved its claws casually and easily blocked Li Yunfei's attack, and then slapped out with a claw, and the powerful force directly knocked Li Yunfei away.

Li Yunfei fell heavily to the ground, spitting out blood.

"Yunfei!" Lin Ya exclaimed and hurriedly cast magic to treat Li Yunfei.

Li Yunfei struggled to stand up, a look of determination flashed in his eyes, "This guy is too strong, we can't fight him head-on."

Lin Ya nodded, "Then what should we do?"

Li Yunfei thought for a moment and said, "We need to find its weakness."

As he said that, Li Yunfei rushed towards the beast again. This time, he did not just attack with force. Instead, he used his flexible body to deal with the beast, trying to find its weakness.

Lin Ya was also constantly casting spells to interfere with the giant beast's actions.

In his fight with the beast, Li Yunfei discovered that although the beast was powerful, it was relatively slow in its movements. He gradually came up with a plan.

While dodging the beast's attack, Li Yunfei shouted to Lin Ya, "Ya'er, I'll attract its attention, and you can take the opportunity to attack its eyes."

Lin Ya responded: "Okay!"

Li Yunfei took a deep breath, and with all his strength, he rushed towards the beast. He deliberately exposed a flaw to lure the beast to attack him.

The beast was fooled, and opened its bloody mouth to bite Li Yunfei. At this moment, Lin Ya saw the right moment, and a beam of light shot out, accurately hitting the beast's eyes.

The beast roared in pain and swung its claws wildly.

Li Yunfei took the opportunity to launch another attack. He used his newly learned moves and a powerful stream of spiritual power blasted straight towards the giant beast.

Under the coordinated attack of the two, the giant beast finally began to show signs of defeat.

However, just when they thought they were about to defeat the behemoth, several equally powerful monsters appeared in the ruins.

"Oh no, there are still so many!" Lin Ya exclaimed.

Li Yunfei gritted his teeth and said, "Let's fight!"

They once again fought desperately with these powerful monsters, but as time went on, their physical and spiritual strength were gradually exhausted.

Li Yunfei and Lin Ya were covered with scars, and their situation became increasingly critical.

Just when they were about to despair, Li Yunfei suddenly felt a strange force coming from the crystal ball. He was moved and quickly took out the crystal ball.

The crystal ball now burst into dazzling light, and mysterious runes flew out of the ball and began to rotate around them.

After seeing the light of the crystal ball, the monsters seemed very frightened and retreated one after another.

Li Yunfei and Lin Ya looked at each other, both showing surprise in their eyes.

They held the crystal ball tightly and, with the help of its power, began to fight back against the monsters.

With the help of the crystal ball, their strength seemed to be infinitely enhanced, and those monsters that were originally extremely powerful became vulnerable in front of them.

Finally, after a fierce battle, they successfully defeated all the monsters.

Li Yunfei and Lin Ya sat on the ground exhausted, but their faces were filled with smiles of victory.

"We did it." Li Yunfei said softly.

Lin Ya nodded, "Yes, we did it."

However, before they had time to rest properly, a strange wave of vibrations came from the ruins again...
