Han Li chanted an incantation, his ten fingers continuously flicking out a series of magic seals towards the void in front of him.

The formation immediately began to operate. The eight circular patterns within blurred, and from them emerged a series of mysterious golden runes, jumping up and down, intertwining and coiling together, condensing into spherical phantom images in mid-air.

As the magic seals in Han Li's hand changed, with a few "popping" sounds, the spherical phantoms burst open one after another, transforming into clusters of blue flames. The entire formation seemed to be burning.

Just at this moment, the magic seals in his hand shifted, and he uttered a low shout.

A great gust of wind arose!

Clusters of flames floated out from the formation, converging towards the location of the Heavy Water True Wheel.

The fireball enveloping the Heavy Water True Wheel rapidly grew, instantly becoming the size of a millstone. The temperature it emitted sharply increased, and the temperature in the nearby void suddenly rose several times over.

Under the searing of the scorching blue flames, the spiritual patterns on the surface of the True Wheel shone brightly, gradually becoming transparent.

Seeing this scene, Han Li urged the magic seals in his hands even more urgently...

Time flew by, and a month passed in the blink of an eye.

The Heavy Water True Wheel above the formation, enveloped in blue flames, had now become completely transparent, like a crystal-clear blue crystal, emitting bursts of dazzling blue light.

However, these blue lights swelled and contracted uncertainly, constantly rising and falling, as if the Heavy Water True Wheel was unable to support itself and could melt into liquid at any moment.

At the same time, the Water Dao patterns on the True Wheel appeared even more radiant, emitting a strong fluctuation of the Law of Water.

Seeing this, Han Li waved his hand, and seven or eight materials appeared in front of him.

These materials were all blue, but with different shades of color, and they all contained the Law of Water.

He formed a hand seal, and at the same time, flicked his sleeve.

The blue flames in the formation on the ground fluctuated, gradually converging towards the eight circular patterns of the formation.

After a few breaths, all the blue flames in the formation disappeared, gathering entirely within the eight circles, forming eight pillars of blue fire.

He waved his hand, and eight materials flew out, each landing within one of the eight pillars of fire.

Han Li chanted an incantation, and the eight pillars of blue fire began to spin rapidly, transforming into fiery tornado, emitting whistling sounds and a heart-palpitating scorching heat.

Within the fiery tornado, the eight materials melted one after another, transforming into clusters of blue liquid.

Within each cluster of blue liquid, a blue rune emerged, which was the power of the Law contained within the material.

Han Li watched all of this, nodded slightly, and changed the magic seals in his hands again.

The blue liquid in the eight pillars of fire flew out simultaneously, flashing into the fireball where the Heavy Water True Wheel was located.

Han Li took a deep breath, his expression becoming solemn, and he rapidly formed hand seals with both hands.

The fireball around the Heavy Water True Wheel also began to tumble, constantly rotating, forming a rapidly spinning vortex of flames.

The eight pillars of fire in the formation also converged, merging into the vortex of flames, causing it to grow rapidly and the temperature it emitted to rise sharply.

Han Li's expression became increasingly serious, his ten fingers changing like wheels, and beads of sweat began to appear on his forehead.

As the vortex of flames rotated, the eight clusters of liquid gradually merged into the Heavy Water True Wheel.

Each time a cluster of liquid merged in, the blue light emitted by the True Wheel would become brighter by a few points. Within the light, countless blue runes could be seen dancing.

However, this blue light looked very chaotic, and the various blue runes fluctuated in a disorderly manner, causing the entire True Wheel to tremble.

Just at this moment, the Earth Avatar sitting opposite him suddenly widened its eyes, formed hand seals, and the blue light on its body suddenly became several times denser. A thick blue crystalline thread emerged above its head.

Han Li gave a soft shout and pointed with a hand seal.

The blue crystalline thread above the avatar's head flew out and merged into the Heavy Water True Wheel.

Boom!

An incomparably dazzling blue light erupted from the Heavy Water True Wheel, as radiant as the sun, making it impossible to look directly at it. It illuminated the seabed within a radius of hundreds of miles, making it transparently bright.

Within the blue light, a strong Law of Water rippled outwards, causing visible ripples.

At this moment, the blue runes on the Heavy Water True Wheel suddenly stabilized, and then disappeared into the True Wheel.

Han Li raised an eyebrow and rapidly formed hand seals, sending them into it.

Buzz!

The Heavy Water True Wheel emitted a trembling sound, and the blue light it emitted also trembled slightly.

In the next moment, the sea surface within a radius of hundreds of miles fluctuated with the blue light, suddenly violently shaking, causing countless whirlpools to appear on the surface.

Within the originally gentle seawater, countless water blades, water arrows, and water edges suddenly emerged, rapidly rotating and cutting everything into powder.

Within a radius of hundreds of miles, all the creatures in the sea were instantly slaughtered, and a layer of the seabed was also scraped off fiercely.

Seeing this scene, Han Li was slightly startled, and then revealed a look of pleasant surprise.

He then took a deep breath, concealed the joy in his eyes, stopped spewing out azure Infant Flame, and at the same time formed a hand seal, immediately stopping the operation of the formation on the ground.

The Earth Avatar also retracted the blue Infant Flame it was spewing, and all the flames dissipated, leaving only the translucent Heavy Water True Wheel suspended in mid-air.

Han Li opened his mouth and spat out a mouthful of blood essence, which flashed and merged into the Heavy Water True Wheel.

The Heavy Water True Wheel emitted a "hissing" sound, and the translucent wheel body quickly turned black, the scorching temperature rapidly dissipated, and it completely cooled down in a few breaths.

Blue light flashed on the wheel body, and nine gentle blue lights lit up, transforming into nine clusters of Water Dao patterns.

A force of the Law of Water, several times stronger than before, emanated from the newly formed Heavy Water True Wheel.

Seeing this scene, Han Li revealed a look of joy.

After more than a month of hard work, he had finally succeeded.

He looked somewhat tired. He took out a pill and swallowed it. After a flash of azure light on his body, his complexion gradually recovered.

After Han Li breathed a sigh of relief, he looked up and down at the Heavy Water True Wheel in front of him, and the look of satisfaction on his face grew stronger.

This time, the refinement was unexpectedly successful, greatly increasing the power of the wheel. Although he had not really tried it yet, he estimated that its power was at least four or five times greater than before.

The reason for this was, on the one hand, that he was willing to invest heavily, incorporating seven or eight materials containing the power of the Law of Water into the Heavy Water True Wheel at once. These materials were all rare items containing the power of the Law of Water. Many of them were treasures he had acquired over the years through skillful plundering. If used to refine Immortal artifacts, they could also refine one or two Immortal artifacts that were not weaker than the previous Heavy Water True Wheel. Now that they were all incorporated into the Heavy Water True Wheel, the increase in its power was conceivable.

In addition, there was another important reason: the Earth Avatar also injected the thread of the Law of Water condensed through the power of faith into the Heavy Water True Wheel, greatly increasing the power of the Law of Water within it.

Although the thread of the Law of Water condensed by an Earth Immortal is not as pure as that of a True Immortal who has truly comprehended the Law of Water, it should not be underestimated.

While pondering, Han Li summoned the Heavy Water True Wheel into his hand.

Now, holding this wheel in his hand, it was as if he had grasped a vast ocean between his fingers. With just a thought, he could easily mobilize the power of water within a radius of tens of thousands of miles, forming a vast expanse of water.

Han Li tossed the Heavy Water True Wheel into the air and waved his hand, sending out a magic seal.

The Heavy Water True Wheel emitted a dazzling blue aquatic light, and all nine clusters of Water Dao patterns shone brightly, forming a mysterious blue halo.

He closed his eyes, carefully sensing the mysterious changes in the blue halo, trying to comprehend the Law of Water.

Although he was currently mainly practicing the Law of Time, one of the three Supreme Laws, it would naturally be better to comprehend as many Laws as possible if he could.

Now that he had just reshaped this True Wheel, he had gained some insights into the Law of Water during the process, so he naturally wanted to try it while the iron was hot.

Unknowingly, a force of the Law of Water spread out, and the nearby seawater, as if summoned, began to roll and fluctuate again, stirring up huge waves.

At this moment, the water pouch at the Earth Avatar's waist flashed with black light, and a mass of pitch-black Heavy Water shot out from it. It was the Second Layer Heavy Water condensed by the Earth Avatar.

As soon as this mass of Heavy Water flew out of the water pouch, it plunged into the Heavy Water True Wheel like a swallow returning to its nest, quickly merging into it.

The aquatic light emitted by the Heavy Water True Wheel suddenly fluctuated slightly, becoming slightly denser.

This situation was the same as when the Heavy Water True Wheel absorbed First Layer Heavy Water in the past.

"Eh!" Han Li opened his eyes and exclaimed softly, but did not try to stop it.

The Heavy Water True Wheel continued to rotate gently, and one mass after another of Second Layer Heavy Water flew out of the water pouch, successively plunging into it and merging with it.

Due to the limited time, the Earth Avatar had not condensed much Second Layer Heavy Water, and it was soon all flown out.

After absorbing this Second Layer Heavy Water, the blue light emitted by the True Wheel became brighter and clearly heavier.

Han Li's eyes flickered, and he was both surprised and delighted.

When the Heavy Water True Wheel was first refined, its power was not very great. After absorbing a large amount of First Layer Heavy Water, its power soared, and it became one of his trump cards.

Unfortunately, the Heavy Water True Wheel later reached a limit and could not absorb more Heavy Water, stopping its growth.

Unexpectedly, after being re-refined at this moment, the Heavy Water True Wheel began to absorb Heavy Water again.

The power of this wheel is already extraordinary. If it can go a step further...

At the thought of this, Han Li waved his hand, and a stream of First Layer Heavy Water flew out of the water pouch on his body, wrapping around the Heavy Water True Wheel.

The Heavy Water True Wheel was surrounded by blue light, but it seemed to resist somewhat, not absorbing this First Layer Heavy Water.

Seeing this situation, Han Li frowned slightly. After thinking for a moment, he quickly discovered the reason.

The Heavy Water True Wheel was re-refined this time, not only greatly increasing its power, but also greatly purifying its internal vitality.

Compared to it, First Layer Heavy Water was already on a lower level. Absorbing it would not only not increase its power, but would also hinder it.

"It seems that I have to refine all the First Layer Heavy Water..." He muttered, and immediately flipped his hand and took out a water pouch, handing it to the Earth Avatar.

There were only about three years left before the Immortal Mansion was born, and time was very tight. The more Second Layer Heavy Water he could condense, the more the Heavy Water True Wheel's power would increase.

The Earth Avatar took the water pouch and waved his hand, summoning a large mass of First Layer Heavy Water from it.

At the same time, he activated the cultivation technique, and a dazzling blue light appeared on his body. Streams of power of faith were transmitted through the air, and a hair-thin blue light thread emerged above his head.

Han Li looked at this blue light thread and smiled wryly.

The Earth Avatar had injected all the Law of Water that he had condensed bit by bit over thousands of years through the power of faith into the Heavy Water True Wheel. Now, his cultivation had been greatly damaged, and if he wanted to re-condense the power of the Law, he would have to start all over again.
