The City Lord's mansion has turned into a wasteland, shrouded in thick mist, resembling a ghostly realm.

In a corner of this ghostly realm-like City Lord's mansion, Lu Yu and Chu Tiange stood at the edge of a pitch-black hole, with Chu Tiange peeking into the dark abyss and then turning to look at Lu Yu.

"Is this the place?"

"Yes." Lu Yu nodded in response.

The earth veins naturally merge with the ground, not emitting any fluctuations; only by seeing and touching them personally can one feel the earth veins.

Just standing at the edge of the hole, Lu Yu could not see the earth veins beneath the ground.

After receiving Lu Yu's affirmation, Chu Tiange jumped into the hole. Lu Yu stood at the edge, vigilant of the surroundings, preventing others from disturbing Chu Tiange as he cut off the connection between the earth veins and the sand giant army.

Wanyan Shahe was able to control the enormous sand giant army spanning over a thousand miles by relying on the earth veins to harness the spiritual qi of the land.

Under his deliberate activation, the power of the earth veins was released, affecting the area's spiritual qi and thus spawning an enormous sand giant army. The key elements were the earth veins, sandy soil, and the secret technique for shaping the sand giants.

As long as the power of the earth veins is returned to its original converged state, the spiritual qi supply to the sand giant army can be cut off, causing the entire sand giant army to collapse.

The treasure garment on Chu Tiange's body radiated golden light as he hovered above the entrance to the earth veins, unaffected by its power, and directly descended into the earth veins.

He took out the most crucial treasure of this operation—the Earth Vein Planetary Instrument.

A slowly rotating globe was surrounded by four golden dragons; numerous fine lines sparkled on the globe, forming the image of a divine dragon, representing the dragon pulse of the Dazhou dynasty.

Chu Tiange performed a ritual with the Earth Vein Planetary Instrument, a crack splitting open on his fingertip from which a drop of blood glimmering with golden brilliance flew out, dividing into four parts that landed in the mouths of the four golden dragons.

The dragon eyes moved, becoming lifelike as if they had gained life.

The four dragons swirled, forming the stance of a divine dragon playing with a pearl, escorting the core of the Earth Vein Planetary Instrument towards the chaotic-colored earth veins.

Falling into the earth veins, the four golden dragons connected head to tail, rotating around the Earth Vein Planetary Instrument, which vibrated, releasing a special power that spread through the earth veins.

An extremely thin, inconspicuous white line gradually formed on the Earth Vein Planetary Instrument.

Judging from its position, it was merely an unnoticeable whisker on the divine dragon of Dazhou, and even one in the outermost corner.

When the white line, representing the earth veins beneath Black Sand City, fully formed on the Earth Vein Planetary Instrument, it meant this earth veins would be included within the range of the Dazhou dynasty's dragon pulse, becoming one of its dragon veins.

For nature near ten thousand miles around Black Sand City, connecting to Dazhou dynasty's dragon pulse was a good thing.

The weaker dragon veins would receive nourishment from the powerful ones, increasing the concentration of spiritual qi within ten thousand miles around Black Sand City, raising the output of natural treasures, making it easier for monsters to gain intelligence and for Martial Cultivators to break through their ranks.

But for those wishing to independently control a kingdom, it was a bad thing.

This meant that the area within ten thousand miles of Black Sand City, influenced by the earth veins, fell under the control and supervision of the Dazhou dynasty.

The Dazhou dynasty has a department that specifically monitors changes in national fortune through the dragon pulse.

If someone wanted to establish an independent nation, it would certainly disrupt the Dazhou dynasty's fortune, be detected by the Dazhou government, and be snuffed out in the cradle.

Like this time, with the "Ten Thousand Miles Cliff Great Wall" orchestrated by the Sand King Hall, if the earth veins beneath Black Sand City had become part of the Dazhou dynasty's dragon pulse, the fortune would change as soon as they entertained the thought, alerting the Dazhou government.

They would be given no time to plan and the Sand King Hall would be directly destroyed.

Chu Tiange hovered above the earth veins, quietly watching as the Earth Vein Planetary Instrument integrated this earth veins into the Dazhou dragon pulse range. Once succeeded, severing the connection between the earth veins and the sand giant army would be effortless.

What puzzled him was that this earth veins should have been under someone's control, so why was there no resistance when the Earth Vein Planetary Instrument operated?

This situation usually only occurred during the process of assimilating ownerless earth veins.

However, this was also a good thing; he didn't need to expend any effort, simply waiting for the Earth Vein Planetary Instrument to complete the assimilation of the earth veins.

Chu Tiange's presence in Black Sand City was not solely out of concern for Chu Tianhe's danger, but this mission was also a major contribution undertaken by the Chu King Residence on his behalf.

Assimilating a dragon pulse, regardless of the scale of the earth veins, was undoubtedly a significant achievement.

Completing this task would earn him enough merit to access the imperial palace treasury and acquire something of great importance to him.

Success was the only option; failure was not permissible.

At this moment, at the core of the earth veins, Wanyan Shahe was struggling to resist the control of the Sand King Hall, having no time to deal with Chu Tiange.

His body had already merged with the earth veins; by controlling his body, he could indirectly control the earth veins.

It's unknown what method the Sand King Hall had used to contest for control over his body.

In the Sand King Hall, within the Earth Vein Eye Stone Chamber, High Priest Sha Qian stood before the Earth Vein Eye. Within the Earth Vein Eye was Wanyan Shahe's body, already appearing a chaotic color.

Sha Qian's eyes erupted with astonishing divine light, battling for control over Wanyan Shahe's body.

Within the food Wanyan Shahe had consumed at the Sand King Hall was the presence of Sha Lingzi, a byproduct of Sha Qian's divine soldiers.

Sha Lingzi had thoroughly merged with Wanyan Shahe's body, enabling Sha Qian to control Wanyan Shahe's body through Sha Lingzi.
