Ouyang Tianchen and the others never considered using a low-grade Immortal-Slaying Cannon to deal with the disciples of the Dao Saint Sect.

The cultivator is too agile; it is difficult to hit him when he is not under control.

However, using a low-grade Immortal-Slaying Cannon to bombard the Dao Saint Sect's formation is just right.

With a wave of his right hand, Ouyang Tianchen...

Ten low-grade Immortal-Slaying Cannons fired simultaneously.

Boom...

The Immortal Extinction Cannon shone with intense light as it headed straight for the Dao Saint Sect's mountain gate.

The Dao Sheng Sect disciples guarding the mountain gate all took action.

They used either supernatural powers or magical artifacts to intercept them.

However, the power of the Immortal Extinction Cannon is truly extraordinary.

The intense light broke through layers of interception and instantly struck the Dao Sheng Sect's defensive formation.

The pale blue light screen trembled slightly from the impact.

Then it returned to its original state.

Although the low-grade Immortal-Slaying Cannon is quite powerful, the second-tier defensive immortal array is even more formidable.

The Dao Sheng Sect's mountain gate formation has been maintained for millions of years.

It was already as solid as an iron barrel.

Unless Ouyang Tianchen and his group can obtain multiple mid-grade Immortal-Slaying Techniques for continuous bombardment.

Otherwise, don't even think about easily breaking through the Dao Sheng Sect's mountain gate formation.

Seeing that the attack effect of the low-grade Immortal Extinction Cannon was not satisfactory.

Ouyang Tianchen and the others were not disappointed.

They were already prepared.

If the Dao Sheng Sect's mountain gate formation were so easily breached...

That wouldn't have lasted until now.

They might have been wiped out long ago.

With a flick of his right hand, Ouyang Tianchen produced a long-handled hammer.

He mustered all his strength, and his immortal energy surged wildly.

The celestial weapon hammer rapidly expanded, and the enormous hammer phantom slammed down towards the mountain gate formation.

at the same time.

Ouyang Tianchen shouted loudly.

"If we all join forces, the destruction of the Dao Saint Sect will take place today."

Eight Golden Immortals and nearly a thousand True Immortal cultivators simultaneously employed their respective methods.

They launched attacks on the Dao Sheng Sect's mountain gate formation.

A great battle broke out instantly.

The surrounding seawater, due to the surging of violent immortal energy, stirred up towering waves.
