Autobiography of Li Yunfei, a time traveler

While Li Yunfei and his companions were still exploring the ruins, the foreign army had quietly approached the Sword Qi Great Wall.

Outside the city, a large mass of foreign soldiers came like a tide. They had ferocious faces and sharp weapons, and exuded a strong murderous aura.

The soldiers on the city wall soon discovered this situation, and the alarm sounded throughout the Jianqi Great Wall in an instant.

"Foreigners are invading!" the soldiers shouted and quickly entered combat status.

Li Yunfei, Lin Ya and others also hurriedly withdrew from the ruins. They looked at the foreign army outside the city with serious expressions.

"I didn't expect them to come so quickly." Li Yunfei gripped the sword tightly in his hand.

Lin Ya's eyes were firm, "No matter what, we must defend the Sword Qi Great Wall."

The man in black robe stood aside, silent, but the aura he exuded became increasingly deep.

The foreign leader rode on a huge strange beast and looked at the Sword Energy Great Wall with a greedy smile.

"Attack!" He gave the order, and the foreign army rushed towards the city wall like a tide.

The soldiers on the city wall fought hard and shot arrows at the foreign soldiers like rain, but the foreign soldiers were numerous and rushed up one after another.

Li Yunfei and Lin Ya led a team of elite soldiers down the city wall and engaged in close combat with the foreign soldiers.

Li Yunfei wielded the sword in his hand, and each sword could kill several foreign soldiers. Lin Ya performed a wonderful spell, and rays of light exploded among the foreign soldiers.

However, as foreign soldiers continued to pour in, they gradually felt that they were overwhelmed.

Seeing this, the man in black robes also joined the battle. He flashed and shuttled among the foreign soldiers like a ghost. Wherever he went, foreign soldiers fell one after another.

Under their tenacious resistance, the attack of the foreign army was temporarily curbed.

But the foreign leader was not reconciled, and he ordered a more violent attack again.

This time, the foreign race sent some powerful beasts and mysterious masters of magic.

The beasts roared and rushed towards the city wall. They were so powerful that they easily destroyed the fortifications on the city wall. Under the cover of the foreign soldiers, the magic masters cast various powerful spells, posing a huge threat to the soldiers on the city wall.

Li Yunfei and his men had to divert their attention to deal with these new enemies.

During the fierce battle, Li Yunfei suddenly discovered that a foreign magic master was quietly going around behind the city wall.

"Not good!" He was shocked and quickly chased after the magic master.

When the magic master saw Li Yunfei chasing him, he sneered and sped up to a weak point in the city wall.

Li Yunfei tried desperately to catch up, but he was still a step too late. The magic master successfully broke through the defense of the city wall and rushed into the city.

"Stop him!" Li Yunfei shouted.

The soldiers in the city rushed forward, but the magic master was too powerful and easily broke through their blockade.

Li Yunfei was extremely anxious. He chased after him desperately and started a desperate fight with the magic master.

After a fierce battle, Li Yunfei finally defeated the magic master.

But at this time, the battle outside the city was still very fierce, and the situation of the Sword Qi Great Wall was still very critical.

Li Yunfei, Lin Ya and others stood tiredly on the city wall, looking at the endless stream of foreign troops outside the city, their hearts filled with worry.

"This is not a solution." Lin Ya said.

Li Yunfei nodded, "We must find a way to break this deadlock."

Just as they were thinking about countermeasures, the man in black robe suddenly said, "I have an idea."

They quickly looked at the man in black robes, "What's the solution?"

The man in black robe smiled mysteriously, "We can use the power in the ruins."

Li Yunfei's eyes lit up, "The power in the ruins? But we haven't fully mastered it yet."

The man in black robe said: "There is no time now. We can only take a risk and try."

Li Yunfei and Lin Ya looked at each other and finally nodded, "Okay, I'll listen to you."

So they quickly returned to the ruins, trying to use the power in the ruins to fight against the foreign army.

In the ruins, they tried hard to find the power they could use. After some effort, they finally found a powerful formation.

"That's it!" the man in black robe said excitedly.

They quickly activated the formation, and a powerful force immediately spread out.

At the same time, the foreign troops outside the city also felt this powerful force and began to panic.

Li Yunfei, Lin Ya and others took the opportunity to rush out of the ruins with this powerful force and rushed towards the foreign army outside the city.

Under the horrified gaze of the foreign army, this powerful force swept past like a torrent, and the foreign soldiers fell one after another.

The foreign leader's face turned extremely ugly when he saw this. "Damn it! Get out of here!"

The foreign army retreated like a tide, leaving behind corpses and debris all over the ground.

Li Yunfei and his men successfully repelled the foreign army, but they knew that this was only a temporary victory.

"We must master the power in the ruins as soon as possible, otherwise we won't be so lucky next time." Li Yunfei said.

Lin Ya nodded, "Well, let's continue exploring the ruins."

So they returned to the ruins and continued their exploration.
