Chapter 902: Insect Tide Invades

Near noon, a long black line appeared on the distant horizon.

Dong, Dong, Dong!

Three bells rang on the city wall, and all the monks gathered on the city wall almost at the same time, holding various magic weapons, and looking at the distant Ghost Desert vigilantly.

Li Zhou stood by the city wall and said solemnly: "The insect fog is coming! Quickly form a formation!"

As soon as the voice fell, a group of monks standing behind Li Zhou pinched the magic formula with their hands and formed a formation to wait.

At the same time, the light of the magic formation continued to light up on the west city wall, but in the blink of an eye, all the monks guarding the west city wall had completed the formation, and the insect fog in the distance was closer to the city wall.

It was not until this time that Ye Zhou and others were able to see the full picture of the insect fog.

Hundreds of millions of flying spirit insects were like locusts passing through, covering the sky and the sun, and the buzzing sound shook the ground slightly.

Various auras, such as those at the Great Perfection of the Jindan Realm and those at the Foundation Establishment Realm, were released from the insect fog. Even with the city defense array to resist, some monks with lower cultivation were still shocked by these auras and became pale and listless.

Wherever the insect fog passed, heavy yellow sand was rolled up, forming a sandstorm, blocking the monks' vision.

Soon, the insect fog and the sandstorm were only a hundred feet away from the west city wall.

The insect fog had entered the attack range of the array.

"Pass my order, attack!"

The old man in Taoist robes had led people to the city wall to give orders without knowing when.

With his order, various arrays on the city wall began to operate with a bang, and countless colorful array lights lit up on the city wall one after another.

Tens of thousands of ice cones, fireballs, poisonous fog and other attack methods flew out from the city wall and crashed into the insect fog like missiles. Soon, a dense layer of spirit insect corpses piled up on the ground.

However, most of these dead spirit insects were in the foundation building stage, and only a few were in the core forming stage.

The spirit insects that made up the insect fog seemed to be unable to sense the danger. The death of their companions could not stop them, and the insect fog continued to approach the city wall.

Seventy feet, fifty feet, thirty feet.

Seeing the insect fog getting closer and closer, the old man in Taoist robes waved his sleeves and said, "Do it!"

The voice was like thunder, resounding throughout the entire western city wall.

On the city wall, more formations began to operate with a bang, and the monks urged the magic weapons to form formations to attack the insect fog.

Outside the city wall, the insect fog had already covered the sky and the sun, and all the light was blocked by the insect fog and the sandstorm. With the bright light of the formation as bright as day, it was still possible to see clearly. Countless spirit insect corpses fell to the ground like a rainstorm.

Not long after, the ground was covered with a thick layer of spirit insect corpses, and no trace of yellow sand could be seen.

Under the intensive attack of various formations and magic weapons, the speed of the approaching insect fog was obviously slowed down a lot.

But before the monks could catch their breath, several clear and strange whistles sounded from the depths of the insect fog, and the insect fog stopped moving forward.

A monk saw this scene and said with joy: "Is the insect fog going to retreat?"

No one around answered him, because everyone's mind was attracted by a dull rustling sound.

This sound was not unfamiliar to the monks who often went in and out of the Ghost Desert. It was the sound of spirit insects devouring food.

As the rustling sound approached, a monk who practiced pupil skills exclaimed: "Insect tide! It's an insect tide coming!"

Insect tide!

The faces of the monks changed drastically, and they were all on high alert.

Soon, a swarm of various spirit insects was seen crawling over the densely packed spirit insect corpses on the ground, devouring the spirit insect corpses while approaching Xianliu City.
