Chapter 87

Since the battle against Jiang Taimo as a three-headed demonic hound, it has been more than three months.

During these days, major forces have been searching in Black Dragon City. As time passed, with no clues, more and more forces and martial artists seeking opportunities gradually left.

In the underground mine beneath Peach Source Valley.

Yitian and his Reincarnation Team were mining essence stones on a large scale.

Hundreds of tribal warriors were mining day and night, and their mining area was near the core of the mine, extracting high-grade essence stones.

It's important to know that the essence contained in a high-grade essence stone is much more condensed and substantial than that in ten thousand low-grade essence stones.

Mining a single high-grade essence stone is definitely more efficient than laboriously mining thousands of low-grade essence stones.

However, although they had already dug a tunnel leading to the core of the essence vein mine,

Due to the central area and its surroundings of the essence vein mine being continuously refined by essence over time, the rocks had become as hard as metal, making the mining speed very slow.

More importantly, the air near the core tunnel was extremely thin, making it impossible to work for long periods. Even though they were all high-level martial artists, they couldn't last long.

Therefore, they took turns entering to mine for a short time and then came out. The rest of the time, they mined medium-grade essence stones in the inner area of the essence vein mine, occasionally finding high-grade essence stones.

Medium-grade essence stones are different from low-grade essence stones. They contain extremely dense essence, which can be seen from their appearance, emitting a jade-like luster. High-grade essence stones are the most perfect top-grade jade in the world, crystal clear, naturally formed, and without any impurities.

For the tribal warriors mining in the essence vein mine, as long as they could absorb, they could absorb essence stones without limit, but they were not allowed to keep them privately.

Yitian was the same during these months.

Faced with such a treasure trove, Yitian would not let it go easily.

Almost all the essence stones he mined were absorbed by his Star Mud Avatar.

The Star Mud Avatar absorbed tens of thousands of medium-grade essence stones and hundreds of high-grade essence stones, gradually transforming from a deep red to a blackish red, with a faint black light shining.

Yitian saw the hope for the Star Mud Avatar to continue advancing and transforming, which gave him even more motivation.

This was a once-in-a-lifetime opportunity.

During the months in the underground mine, Yitian went out to hunt three times, and the rest of the time he was mining essence stones on a large scale.

His Supreme Yang True Qi was undoubtedly powerful, and the sword qi he wielded was incredibly sharp, making his mining speed several times faster than others.

Thus, another two months passed.

In these six months, the major forces and various experts who had found nothing all left, and the land of Black Dragon City returned to peace, much to the relief of the city lord and the major forces.

After all, the appearance of experts from all over the Tianfeng Imperial Kingdom, with human-rank experts occasionally showing up, could destroy their forces with a single hand. During this period, the major forces in Black Dragon City were always on edge, fearing that they would offend an expert and face a catastrophic disaster.

After months of frenzied absorption, the Star Mud Avatar finally advanced to a blackish red.

On this day, Deputy Leader Yizhen gathered Yitian, Yifeng, Yishan, Yili, Yikuang, and Yihong.

"After six months of searching, the major forces have all withdrawn, and the news of the heavenly treasures has been forgotten. Therefore, today we will enter the core area to mine essence crystals."

Yizhen said to Yitian and the others.

He had been looking forward to this day for a long time, and today it was finally happening.

If they mined essence crystals, it would be a huge surprise for the tribe.

The tribal leader and the great elders had been at the peak of the ninth rank for many years. With just one or two essence crystals, they could greatly accelerate the refinement of spirit acupoints, refine their true qi to the extreme, and break through to the human rank, condensing true essence.

If they had essence crystals, their cultivation speed would be incredibly fast, and they could almost skip the refinement of true qi.

Just like the other elders, Yizhen, and Yitian, if they used essence crystals to cultivate, they could reach the peak of the ninth rank in less than ten days, with their true qi extremely refined, equivalent to the results of decades of hard cultivation.

This is the preciousness of essence crystals.

If a force had a strong foundation and used essence crystals to cultivate their descendants, they could reach the peak of the ninth rank or even the human rank in just one or two years, mass-producing human-rank experts.

Yitian and the others were all delighted.

If they had essence crystals, they were confident they could reach the human rank in just a few months.

The human rank is the true entry point of martial arts.

Since the essence concentration in the core area of the essence vein mine had reached an unimaginable level, the rocks in that area were as hard as spirit weapons, which ordinary martial artists could not destroy.

Therefore, Yizhen had Yitian and his Reincarnation Team go to mine the essence crystals.

Yizhen led Yitian and the others deep into the core area, which had not been entered until now.

In front of them were huge rocks blocking the way.

When Yizhen and the others mined to the core area, the immense essence pressure inside exploded, causing the essence light to shoot up to the sky. Later, Yizhen and the others blocked it up.

Yizhen led Yitian and the others to start clearing the tunnel.

Boom! Boom! Boom!

The large rocks were continuously moved aside.

When Yitian and the others moved the last rock, a surge of essence rushed towards them.

They took a light sniff, and it seemed as if the essence was absorbed into their lungs, bringing a cool, refreshing feeling, invigorating their spirits, and filling their bodies with strength. At the same time, they could feel a powerful impact, boundless and endless.

The essence continued to pour out like a flood, rushing into the mine and spreading out.

"Fortunately, it has already exploded once before, so the essence in the core area has been mostly released. Otherwise, the impact of the essence tide would be too strong for us to withstand!"

Yizhen explained to Yitian and the others.

This was the residual essence in the core area of the essence vein mine, which would not cause the same kind of celestial phenomena as before.

In front of Yitian and the others was a type of luminous rock, refined by essence for countless years, with a hardness comparable to low-grade spirit weapons.

This had been tested by Deputy Leader Yizhen before.

Thus, in the following days, Yizhen, Yitian, and the seven members of the Reincarnation Team, including Yifeng and Yishan, began mining in the core area. Sword qi and blade qi crisscrossed, cutting into the rocks, continuously chopping off fist-sized pieces.

They worked hard for half a day but only managed to mine less than ten feet deep.

At this moment, Yitian slashed at the rock in front of him, and with a loud boom, a dozen rocks exploded. A faint light suddenly shone, illuminating the cave clearly.

A fist-sized crystal was mostly embedded in the rock layer.

"Essence crystal!"

Yitian, Yizhen, and the others were all elated.

This was the first time they had mined an essence crystal, so they all sped up, continuously breaking the rocks around the essence crystal.

Finally, the essence crystal fell out of the rock.

Yizhen rushed over like a leopard, picked up the essence crystal, and the fist-sized crystal was like the most beautiful treasure in the world, emitting a soft, dazzling light.

Yitian and the others could even see a small pool of essence liquid inside the crystal, sparkling like stars in a sky of azure, with countless stars shining together.

The most precious part of the essence crystal is the essence liquid inside, which is extremely pure and refined, containing immense energy, enough to significantly increase the cultivation speed of any cultivator in a very short time.

Yizhen carefully stored the essence crystal in his storage bag.

After that, Yizhen and all the members of the Reincarnation Team worked even harder.

This was the legendary essence crystal!

Even in Jingmu County, there had never been a report of an essence crystal appearing. Major forces would never exchange it, and it was likely that only the capital of the Tianfeng Imperial Kingdom would occasionally see the appearance of an essence crystal, each time causing a significant stir.
