With the force of a sudden enlightenment, ten thousand years of cultivation poured into Gu Xuan's meridians, limbs, and bones like a surging river.

In the blink of an eye.

His aura gradually became unpredictable.

The colorless spiritual energy within his body was rapidly transforming into immortal energy containing a trace of golden light!

The bottleneck of the Remnant Immortal Realm can be broken with a single touch!

Gu Xuan, having started from the half-step remnant immortal realm, naturally stepped into the remnant immortal realm and did not stop there.

They only stopped when they reached the peak of the Remnant Immortal Realm.

In this realm, the vast spiritual power surrounding the body gradually begins to transform into immortal power, and it is also known as the terrestrial immortal realm.

Possessing the power to create heaven and earth, it can unintentionally bring prosperity to a region, or instantly plunge it into destruction.

A single word uttered can affect hundreds of millions of lives.

Furthermore, reaching the peak of the Remnant Immortal Realm grants one the qualification to ascend to the Upper Realm.

At that time, the Heavenly Gate will open, and one will ascend to immortality!

This moment.

Gu Xuan finally became the greatest immortal in the mortal realm!

......

Liu Ruyan and Jiang Qingqing also instantly felt an extremely terrifying pressure descend upon the thatched hut!

This gave the two of them the feeling of facing a deity, and they turned to look at their master, Gu Xuan, who was standing in the center of the courtyard.

At this moment, the master seemed to have entered a state of deep meditation.

That terrifying aura, like the mighty power of heaven, was continuously emanating from Master!

At the same time, the two of them suddenly realized that their master was different.

His entire being appeared and disappeared, as if a celestial being had descended to earth, giving people a feeling of being detached from the mortal world, pure and flawless, and transcending the past and present.

The two women were startled!

Master, this is... another breakthrough?!

Right now.

The once cloudless sky was suddenly covered with dark clouds and a strong wind was blowing!

Thunder rumbled through the thick clouds.

It seemed as if countless thunder dragons were rolling and roaring within it.

Boom!

Click—

Streaks of blue lightning, like spider legs, suddenly exploded in the sky!

The dazzling lightning instantly illuminated the entire sky, its brightness even surpassing that of daytime.

Immediately afterwards, countless bolts of lightning rolled in, like a galaxy falling from the sky, rushing down for thousands of miles!

Along with the thunder, a majestic divine might emanated, startling the small animals in Medicine King Valley into scattering in all directions!

Above the sky.

A terrifying vortex of thunderclouds is slowly forming...

This strange phenomenon once again astonished the two women!

Master, what level has this breakthrough reached that has triggered the legendary tribulation of lightning?!
