Blood dripped from Sarloy's elbow, gathering on the ground into drops of blood, like crimson pearls, untouched by dust.

Boom! Two forces compressed to their limit were finally detonated, and the explosion's shock wave swept across the entire City Lord's mansion, even spreading beyond it.

The mist that shrouded the City Lord's mansion was swept away by the shock wave, revealing the scene of the City Lord's mansion before everyone's eyes once more.

The Array at the entrance of the Earth Vein had already vanished, destroyed by the aftereffects of the battle, although no one cared about the Earth Vein entrance right now.

The only person remaining in the City Lord's mansion was the Gale Hall Master, who had lost his rationality and gone berserk; he alone suppressed the Four Symbols Infinite Array composed of four Core Formation Realm generals.

After the explosion's shock wave dissipated, Lu Yu discovered that Sarloy and the others had already retreated.

The White Tiger Slaughter Array hosted by Song Ming also headed in the direction of the Flame Demons, to support the four suppressed Core Formation Realm generals.

The violent Qi Blood within Lu Yu gradually calmed down, while the golden light in Chu Tiange's eyes also converged, exhaustion showing on his somewhat youthful face.

Despite his massive energy expenditure, Chu Tiange hurried back to the Earth Vein, wanting to recover the planetary apparatus and continue the transformation of Black Sand City's Earth Vein.

Standing before the Earth Vein, Chu Tiange's face appeared somewhat pale; the recent battle had heavily drained him. The risk of entering the Earth Vein now was immense, with the slightest misstep leading to assimilation by the Earth Vein.

Lu Yu volunteered, saying: "Why not let me go."

At the moment, none of the tasks had been completed, and among them, the Earth Vein was undoubtedly of utmost importance.

Chu Tiange hesitated for a moment, understanding that in his current state it really wasn't suitable for him to enter the Earth Vein, so he shared how to control the planetary apparatus with Lu Yu, allowing him to activate its transformation of the Earth Vein once located.

As for leaking the control method of the planetary apparatus, it wasn't a big deal.

The planetary apparatus could only be activated by royal blood; what Lu Yu received was merely an operational method. Without royal blood, even if he obtained the planetary apparatus, he would be unable to activate it.

Previously, Chu Tiange had already activated the planetary apparatus using his bloodline. Now, as Lu Yu entered the Earth Vein, he merely needed to issue a command to continue the task upon finding the planetary apparatus.

After memorizing the control method, Lu Yu entered the Earth Vein, disappearing from Chu Tiange's sight.

This time, entering the Earth Vein did not lead to the desert world created by Wanyan Shahe. Lu Yu released the extinction power in his right hand, isolating himself from the Earth Vein's effects, and began searching for the planetary apparatus in the boundless chaos of the Earth Vein.

Unable to employ perception for a broad search, Lu Yu could only explore bit by bit, feeling his way toward the planetary apparatus's location.

After an unknown amount of time spent exploring the Earth Vein, Lu Yu sensed a particular fluctuation and instinctively moved in the direction from whence it originated.

In the liquid Spiritual Qi world, Lu Yu was constantly absorbing the surrounding Spiritual Qi, causing his Spiritual Power cultivation to increase rapidly and passively.

This was not necessarily a good thing. Without the extinction power protecting his body, his body might have already been assimilated by the extremely dense Spiritual Qi, turning into a mass of liquid Spiritual Qi.

Even with extinction power protection, the cost of this Spiritual Power increase manifested as blackness quickly spreading through his right-hand bones, with consequences unknown.

Up to now, Lu Yu had yet to understand what impact the blackened bones would have on him.

Having witnessed the tragic results after Wang Hong employed similar power, Lu Yu understood that this influence was likely not beneficial.

To gain powerful strength, a corresponding price must inevitably be paid, and this accumulating unknown cost remained a thorn in Lu Yu's heart.

Like a ticking time bomb with uncertain time left, it made Lu Yu nervously anxious.

Yet, he had no choice but to frequently utilize this power with unknown costs.

In light of this, Lu Yu also thought of a solution: obtain a Seed of Demons to gain another chance at life, coping with the unknown cost.

With a plan in mind, Lu Yu no longer resisted the rapid growth of his Spiritual Power cultivation.

"I see it."

Lu Yu noticed an incongruous golden light emerging from the chaotic Earth Vein, realizing he had found the planetary apparatus, having previously inquired Chu Tiange about its appearance.

The planetary apparatus restored to its four-dragon-jeweling-pearl form, staying put without moving.

When Lu Yu approached, he saw several blurred human faces, with the planetary apparatus positioned below them.

Looking at these expressionless human faces, Lu Yu reached out to grab the planetary apparatus, without any hands suddenly emerging to seize him.

In the Earth Vein, besides a half-dead Wanyan Shahe, Lu Yu was likely the only living person.

The few human faces before him were of those not yet fully assimilated by the Earth Vein, their bodies blocking the planetary apparatus from drifting aimlessly.

If it weren't for them blocking the planetary apparatus, who knows where it might have drifted, and how long Lu Yu would have had to search before finding it.

"Thank you," Lu Yu expressed his gratitude to the few individuals about to vanish completely.

He grasped the planetary apparatus and headed toward the center of the Earth Vein, where a bright sphere shone through the thick chaos, visible even to Lu Yu.

That was the Sun within the Earth Vein, the core of the Earth Vein.

Having obtained the planetary apparatus, Lu Yu did not activate it immediately.

Arriving before the sphere, inside it floated a body formed of crystal, the body Wanyan Shahe left for himself, now floating motionless within the sphere, eyes vacant.
