The Earthly Avatar pinched its fingers, operating the Black Sea Heavy Water Sutra.

Streaks of blue light emanated from the blue filaments, within which countless minute blue runes could be faintly seen, illuminating the layer of heavy water in its hands.

The layer of heavy water immediately roiled, beginning to condense and refine, slowly transforming into second-layer heavy water.

However, the speed was extremely slow.

Han Li sighed softly upon seeing this.

The speed of condensing heavy water was already very slow, and with the avatar's Law of Water greatly damaged, naturally, the speed wasn't going to be any better.

But if this was the speed, not much second-layer heavy water could be condensed in three years.

After a moment of contemplation, he flipped his hand and took out the palm-sized bottle, inside which was a drop of green liquid.

Han Li pinched his fingers, and two streaks of azure light shot out from his hands, entering the bottle.

Rumble!

The sky above the sea area changed color, and countless dark clouds appeared, with the earthly spiritual Qi boiling as if it were being stirred…

Several days later.

Han Li's expression was as usual as he twirled a Time Crystal in his hand.

With his current profound immortal spiritual power of the Late-stage True Immortal Realm, condensing Time Crystals was no longer a burden.

After a moment of contemplation, he waved his hand, and the Time Crystal flew to the top of the Earthly Avatar's head. The golden filaments within the crystal flashed and merged into the blue light filaments.

The blue light filaments immediately shone brightly, with a layer of golden light appearing on the surface.

Dazzling blue light emanated from the light filaments, illuminating the layer of heavy water.

The layer of heavy water immediately roiled violently, rapidly condensing and shrinking, transforming into second-layer heavy water at a speed many times faster than before.

Before long, all of this layer of heavy water had been transformed into second-layer heavy water.

The Earthly Avatar put it away, then waved its hand again, taking out another layer of heavy water and continuing to refine it.

Han Li breathed a sigh of relief upon seeing this.

Fortunately, Time Crystals were also useful for condensing second-layer heavy water, otherwise, he would have had a headache.

His figure flickered, and he flew upwards, quickly arriving at the surface of the sea.

Han Li scanned his surroundings, then flew towards the vicinity, landing on a sea reef near U Meng Island.

Although the seabed was quiet and safe, sunlight and moonlight couldn't penetrate there, making it impossible to condense the green liquid.

He waved his hand, and rows of array flags shot out, landing near the reef.

This place was remote, so Han Li didn't bother with elaborate arrangements, stopping after setting up a few formations. He sat down cross-legged, taking out the palm-sized bottle and placing it beside him.

Han Li pondered for a moment, then waved his right hand.

A row of materials appeared before him, precisely the materials for refining the Gold Soul Pill.

The materials for the Gold Soul Pill had already been collected, but he had been busy before and had no time to refine it.

Now that he had nothing to do, he could take the opportunity to refine the Gold Soul Pill, in case he needed it in the future.

Han Li closed his eyes and sat quietly for a while, adjusting his breathing. Then, he flipped his hand and took out the silver pill furnace. He opened his mouth and spat, and the Silver Flame Boy shot out, landing at the bottom of the pill furnace, transforming into a raging silver flame.

After doing all this, he flipped his hand, took out Tao Yu's Nascent Soul, which was bound by layers of restrictions. After removing the restrictions, he threw it into the pill furnace.

He opened his mouth and spat out a stream of azure Infant Fire, which merged with the silver flames. The temperature inside the pill furnace immediately increased greatly.

Enveloped by the two-colored flames, the Golden Immortal Nascent Soul was fiercely tempered, with faint wisps of spirit snake-like golden light flowing up and down its surface.

Han Li nodded slightly upon seeing this, focusing his attention on the changes occurring on the Nascent Soul while constantly pinching his fingers, urging and controlling the two-colored flames within the pill furnace.

Time passed bit by bit, and in the blink of an eye, more than half a month had passed.

The Nascent Soul inside the pill furnace had shrunk by more than half, transforming into a fist-sized golden bead. Strands of crystalline light waves flowed on the bead, making it look quite special.

After a moment of contemplation, Han Li took another material and threw it into the pill furnace…

In the blink of an eye, another half month had passed.

The earthly spiritual Qi above the sea suddenly roiled, and various phenomena appeared in the void.

Streams of golden light emerged, condensing into golden flowers that bloomed in competition.

At the same time, these golden lights emitted celestial music that lingered for a long time.

Han Li's face lit up with joy as he looked at the pill furnace in front of him.

A golden pill the size of a dragon's eye floated above the pill furnace, emitting dazzling golden light. It was the Gold Soul Pill.

Although the Gold Soul Pill required harsh spiritual materials for refinement, the refinement process itself was not complicated. With Han Li's current pill refinement skills, he successfully completed it in more than a month with full concentration.

Full of spirituality, a faint human figure vaguely appeared on the pill, as if the pill had a soul.

A strange medicinal fragrance emanated from the Gold Soul Pill, making one feel refreshed.

Han Li felt his mind's soul power fluctuate after the medicinal fragrance entered his nose, with faint signs of a breakthrough.

"As expected of a pill that can transform the soul," Han Li praised, taking out a jade box, placing the Gold Soul Pill in it, and then affixing several talismans before putting it into his storage bracelet.

He then waved his hand towards a certain void to the side, and the palm-sized bottle flashed and floated in front of him. He cast a spell, sending a stream of magical power into it.

The earthly spiritual Qi near the reef violently roiled, converging towards the palm-sized bottle like a tide.

Upon seeing this, Han Li took a deep breath, and two extremely pure azure light beams shot out from the palms of his hands, entering the bottle…

Several days later, the roiling earthly spiritual Qi near the reef returned to calm.

Han Li waved his hand, dispelling the azure light beams shot from his hands. The palm-sized bottle slowly fell, and the green liquid inside transformed into a Time Crystal.

After putting away the bottle, he flipped his hand and took out a pill, swallowed it, and then waved his hand, releasing a stream of azure light, wrapping the Time Crystal and flying towards the seabed.

A moment later, the azure light shot back from the seabed, carrying a black bag, which was the water bag.

The azure light flew somewhat sluggishly, as if carrying a large mountain.

Han Li reached out and caught the water bag, feeling his arm sink slightly.

He released his spiritual sense and scanned it, discovering that the bag was filled with about a pond's worth of second-layer heavy water.

Han Li was overjoyed. It seemed that with the acceleration of the Time Crystal, even with the Earthly Avatar's Law of Water greatly damaged, the speed of condensing second-layer heavy water was still quite fast.

While pondering, he mentally urged a spell, and the Heavy Water True Wheel emerged behind him, flashing and flying in front of him, gently rotating.

Han Li pinched his fingers at the water bag, and a fist-sized ball of second-layer heavy water shot out from it, wrapping around the Heavy Water True Wheel.

The nine groups of Water Dao patterns on the Heavy Water True Wheel emitted a shimmering blue light, which suddenly brightened, illuminating the vicinity with a bright blue color.

The blue light emitted by the nine groups of Dao patterns stretched and contracted, like nine large mouths, rapidly devouring the second-layer heavy water.

Before long, all of this ball of heavy water had been devoured, and the water light emitted by the Heavy Water True Wheel brightened again.

Han Li's hands moved non-stop, pinching his fingers again, and another ball of heavy water flew out, merging into the True Wheel.

Blue light flashed on the reef, and balls of second-layer heavy water flew out, continuously merging into the True Wheel.

This continued for about a night, and finally all the heavy water in the water bag had been completely merged into the Heavy Water True Wheel.

The current True Wheel emitted dazzling blue light, and as it gently rotated, it burst out with a shocking force, causing the nearby void to tremble slightly.

Han Li's eyes lit up with joy. After absorbing this heavy water, the True Wheel's power had obviously increased by a notch.

Moreover, unlike when he absorbed first-layer heavy water, this time he absorbed almost a pond of second-layer heavy water, and the Heavy Water True Wheel still did not show the kind of unbearable burden or sudden disconnection of his mind that it had before.

Han Li's gaze shifted, landing on the nine groups of Water Dao patterns on the True Wheel, and a thoughtful look appeared on his face.

The Water Dao patterns on the True Wheel had greatly increased after re-refining, so its ability to withstand heavy water had also greatly improved.

In this way, he was saved from having to slowly refine it with Dan Fire.

He waved his hand, put away the Heavy Water True Wheel, and closed his eyes.

……

Three years later.

On the reef, Han Li sat cross-legged, as if he hadn't moved at all during this time.

A dazzling blue light was floating in front of him, next to a ball of heavy water.

Enveloped in the blue light was naturally the Heavy Water True Wheel.

Han Li was not casting a spell to activate it at the moment, but just letting it float in the air. However, one could clearly feel a terrifyingly heavy aura emanating from the light sphere, causing the nearby void to hum and tremble, and visible ripples appeared, as if the void could not bear the weight of the True Wheel.

Han Li pinched his fingers and pointed, and the Heavy Water True Wheel began to rotate slowly.

The nearby void trembled more and more violently, making drumming sounds. The nearby sea area stirred up a huge commotion, with the seawater roiling and the wind howling, sweeping out in all directions. However, the area around the reef was not affected because it was covered by a restriction.

The blue light of the Heavy Water True Wheel stretched and contracted, enveloping the surrounding heavy water and rapidly absorbing it.

In just a moment, the last bit of heavy water was also absorbed into the True Wheel.

The blue light on the Heavy Water True Wheel suddenly swelled and shrunk, as if it had burped.

Upon seeing this, Han Li waved his hand.

The Heavy Water True Wheel immediately stopped rotating, and the dazzling blue light on it disappeared, landing in his hand.

As the True Wheel stopped spinning, the void also stopped trembling, and everything returned to calm. The nearby sea area also quickly returned to its original state, as if nothing had happened before.

The Heavy Water True Wheel looked no different from before, but the nine groups of Water Dao patterns on it had clearly grown larger, with blue light swirling around them. At first glance, they looked like nine blue vortexes.

A much stronger Law of Water fluctuation emanated from the nine groups of Water Dao patterns.

The nine Law fluctuations were mixed together, converging into a vast Law torrent.

Such a huge Law power, in terms of quantity alone, far surpassed all of Han Li's other immortal artifacts.

In this way, he would have more survival guarantees in the upcoming Immortal Mansion journey, which was full of uncertainties.

A hint of excitement appeared on Han Li's face as he looked up and down at the True Wheel. After three years of continuous absorption of second-layer heavy water, this wheel obviously still had spare capacity, and even the absorption momentum had not weakened in the slightest. In the future, as long as there was enough heavy water, he could continue to make it stronger.
