More than three months have passed since the incarnation of the three-headed demon dog fought against Jiang Taimo.

For so many days, the major forces searched in Black Dragon City, and as time went by, there was not a trace of clues, and gradually, there were constantly forces and warriors who rushed to find opportunities to leave.

In an underground mine under the Taoyuan Valley.

Yitian's reincarnation team, they are all mining Yuanshi on a large scale.

Hundreds of warriors of the tribe are also mining day and night, and their mining area is near the core of the mine, and all they mine are pieces of high-grade Yuan stones.

You must know that the vitality contained in a high-grade yuan stone is larger and condensed than that of 10,000 lower-grade yuan stones.

Every piece of high-grade yuan stone is definitely more efficient than painstakingly mining thousands of low-grade yuan stones.

However, they had already dug a core hole leading to the Yuanmai Mine.

However, due to the central area of the Yuanmai Mine and its vicinity, the quenching of the Yuan Qi has been endured over time, and the rock has become comparable to gold and iron, extremely hard, and the speed of mining is very slow.

More importantly, the air near the core mine was extremely thin and could not work for a long time, even if they were all high-level martial artists, they would not be able to last long.

Therefore, they all take turns to mine for a short period of time and then withdraw, and the rest of the time they mine medium-grade Yuanshi in the inner perimeter of the Yuanmai Mine, and occasionally there will be high-grade Yuanshi.

The middle grade yuan stone is different from the lower grade yuan stone, they contain the vitality is extremely rich, it can be seen in the appearance, exudes a jade-like luster, the top grade yuan stone is the world's most perfect top jade, crystal clear, as if natural, without a trace of impurities.

For the tribal warriors who mine in the Yuanmai Mine, as long as they can absorb it, they can absorb the Yuan Stone without restrictions, but it is forbidden to keep it privately.

Yi Tian did the same during these months.

In the face of such a treasure, of course, Yitian will not let it go lightly.

Almost all of the Yuan Stones he mined were devoured and absorbed by the Star Clay clone.

The Star Clay clone absorbed at least tens of thousands of medium-grade Yuan Stones, hundreds or thousands of high-grade Yuan Stones, and it gradually transformed from dark red to black red, with a trace of black light shining.

Yi Tian saw the hope that the Xingchen mud clone would continue to advance and transform, so he was even more motivated.

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

In the few months in the underground mine, except for the three times he went out to hunt, the rest of the time Yi Tian was mining yuan stone on a large scale.

There was no doubt about his Extreme Yang True Qi, and the sword qi he cast was extremely sharp, and the speed of mining was several times faster than that of everyone else.

In this way, more than two months passed.

In the past six months, the major forces that have gained nothing, the strong people from all sides, etc., have left one after another, and the land of Black Dragon City has returned to calm, which makes the city lord of Black Dragon City and the major forces breathe a sigh of relief.

After all, the strong people from all over the Heavenly Wind Emperor are infested, and the strong people of the human rank appear from time to time, and their forces can be wiped out with one hand, and for a period of time, the major forces in Black Dragon City are all terrified, for fear of offending the strong and encountering a catastrophe.

After these months of crazy devouring, the Star Clay clone has finally advanced back to black and red.

On this day, the deputy leader of Yi Zhen gathered Yi Tian, Yi Feng, Yi Shan, Yi Li, Yi Mad and Yi Hong together.

"After half a year of searching, the major forces have already evacuated, and the news of the heavenly and earthly treasures has faded away, so today, a few of us will enter the core area to mine Yuanjing. ”

Yi Zhen said to Yi Tian and the others.

This day, he has been looking forward to for a long time, and today can finally begin.

If the Yuan Crystal is mined, it will definitely be a huge surprise for the tribe.

Patriarch, the elders of the great clan have been at the peak of the ninth order for I don't know how many years, as long as one or two yuan crystals, they can greatly speed up the speed of condensing the spirit acupoint, refining the true qi to the extreme, breaking through in one fell swoop, condensing the true yuan, and achieving the human level.

If they have Yuan Jing, the speed of cultivation is simply a thousand miles a day, and it can be said that the time for condensing true qi can already be saved.

It's like the other clan elders of the tribe, Yi Zhen, Yi Tian and the others, they are using Yuan Jing to cultivate, I am afraid that they will not be able to cultivate to the peak of the ninth order in more than ten days, and their true qi is extremely condensed, which is equivalent to the results of decades of hard cultivation.

This is where Yuanjing is precious.

If there is a huge amount of power, and Yuan Jing is used to cultivate future generations, I am afraid that it will only take a year or two to cultivate to the peak of the ninth order, or even the human level, and you can easily build a human level powerhouse in batches.

Yitian, they are all happy.

If they have Yuanjing, they are sure to hit the human level in just a few months.

Human level, this is the introduction to martial arts.

Since the concentration of Yuan Qi in the core area of the Yuan Vein Mine had reached an unbelievable level, the rocks in that area were simply as hard as spiritual weapons, and ordinary martial artists could not destroy them.

Therefore, Yi Zhen asked Yi Tian and his reincarnation team to mine Yuan Jing together.

Yi Zhen took Yi Tian and the others all the way into the core area that they had not yet set foot in.

In front of them were boulders, blocking the road ahead.

This is when Yi Zhen and they mined to the core area, the incomparably huge Yuan Qi pressure inside exploded, leading the Yuan Qi to soar to the sky, and was later blocked by Yi Zhen and them.

Yi Zhen led Yi Tian and a few people to start opening up the excavation channel.

Boom! Boom!

The boulder was constantly being moved.

When Yi Tian and the others moved the last stone away, a majestic vitality rushed to their faces.

They sniffed lightly, as if they were all inhaling vitality into their lungs, a burst of coolness, overflowing spirit, as if their bodies were full of strength, and at the same time, they could also feel a powerful impact, boundless.

The majestic vitality was still pouring out like a flood, rushing into the mine, and constantly spreading.

"Fortunately, it has already erupted once before, so the vitality of the core area is almost exhausted, otherwise, I am afraid that even we will not be able to resist the impact of this vitality tide!"

Yi Zhen explained to Yi Tian and them on the side.

This is some of the remaining vitality in the core area of the Yuan Vein Mine, and it will not cause the same vision of heaven and earth as before.

What appeared in front of Yi Tian and them was a glowing rock, which had been tempered by the vitality for an unknown number of thousands of years, and its hardness was comparable to that of a low-grade spiritual weapon, a spiritual soldier.

This is what Deputy Leader Yi Zhen has tested.

So, in the following days, Yi Zhen, Yi Tian, Yi Feng of the reincarnation team, Yi Shan and other seven people mined in the core area, one after another, sword qi, sword qi vertical and horizontal, slashing on the rocks, constantly cutting down fist-sized stones.

They worked hard for a long time, but they only mined less than a foot deep.

At this moment, Yi Tian slashed at the rock in front of him with a sword, and more than a dozen stones exploded with a bang, and a misty light suddenly lit up, illuminating the cave very clearly.

A fist-sized crystal is mostly embedded in the rock formation.

"Yuanjing!"

Yi Tian, Yi Zhen and others all lit up.

This was the first time they had mined the Yuan Crystal, so they all sped up one by one, constantly breaking through the rocks around the Yuan Crystal.

Eventually, the Yuan Jing fell out of the rock.

Yi Zhen rushed over like a leopard and picked up the Yuan Crystal, the fist-sized Yuan Jing was like the most beautiful treasure in the world, blooming with a soft, blurry brilliant light.

Yi Tian and the others could also see through the crystal clear crystal that there was a small amount of Yuan liquid inside the Yuan Crystal, dotted with stars, as if it was an azure sky, and ten thousand stars were shining.

Yuan Jing, the most precious thing is the Yuan liquid in Yuan Jing, which is incomparably pure, condensed, and contains majestic energy, which is enough to make any cultivator's cultivation speed increase greatly in a very short period of time.

Yi Zhen cautiously put this Yuan Jing into the storage bag.

Next, Yi Zhen, everyone in the reincarnation team mined more energetically.

This is the legendary Yuan Jing!

Even if Jingmu County had never heard of the appearance of Yuan Jing, it was impossible for the major forces to exchange it, I am afraid that only the imperial capital of the Heavenly Wind Emperor Kingdom would occasionally have Yuan Jing's appearance, and every time it might cause quite a stir.
