The stone walls change their textures almost at a visible speed, and the colors gradually darken. This is a representation of the fusion of stone and yin qi, so far, the four walls of the grotto can not only further limit the erosion function of yin qi, but also can borrow yin qi and transform into a new material.

It is conceivable that if this place of gathering yin lasts forever, thousands of years later, the monks who occasionally come here may be able to find an ore that has never been found in this world.

After doing this, Yang Zhao squatted down and looked at the dense small holes on the surface, and the blue and white light reflected his face deep blue, like a jade carving.

The concentration of yin qi in the ground is extremely high, constituting a huge source of interference, making the search of a qiēqi machine like a mud cow entering the sea, and there is no news.

Yang Zhao tried to use the earth to explore the surroundings, just as he thought back then, this place of gathering yin was because of the changes in the earth's crust, rising from the extremely deep ground, and was locked in the belly of this mountain, and its yin qi origin was steamed up through the heavy earth and stones, and it became a trick.

Look at the location, where the origin is...... Is it really in the realm of the Nine Shades?

The dividing line between the Great Thousand World and the Nine Shadows Realm was indeed not so obvious, but it was the first time Yang Zhao had seen it like this, which was connected up and down with yin qi.

If this was really the Nine Shadows Qi Vein, it was no wonder that those people in the Succubus Palace had been searching for so long without seeing results, they would never have imagined that such a precious Pure Yin Qi would really flow out of the Nine Shadows Realm.

Yang Zhao's palm swept over the Yin Fire unhurriedly, feeling the unique qi pulsating in it, and he firmly memorized its characteristics. Then the figure shrank. Follow the Yin Qi veins and drill into the ground.

It's been a terrible journey.

Although it is said that the yin fire in the place where the yin gathers above is extremely spectacular, it is the external manifestation of the natural cultivation of the earth vein aura, and the real nine shades of the earth qi are slightly blurred, seemingly absent, extremely restrained, and it is not easy to find out its true source from the interference of several yin veins around.

Yang Zhao walking through the earth and rocks. The flow of time in the outside world has been completely forgotten. He also completely lost his sense of direction, he didn't sleep or eat, but was engrossed in sensing the direction of the yin qi. After a long time, he even felt that the feeling of his five senses was lost. Only a wisp of yin qi remains. Even clearer.

So. When a ray of spiritual light flashed in his mind, Yang Zhao stopped suddenly.

In a moment, the five senses of eyes, ears, nose and tongue returned. This monotonous and dark underground world is also enriched in an instant. The jerky smell of earth and stone and the low sound of water merge in one place, silent and eerie.

"Underground river?"

Yang Zhao took a step forward, and suddenly retracted suddenly, and a long sound of "Zi" sounded in the muffled space, followed by a "pop", and the loose soil cracked a small hole without warning.

Yang Zhao snorted lowly, the speed of his body infiltration accelerated, and he stretched out his hand like lightning, and the surrounding soil and stones did not have any impact on his movements, and the three-finger kickback, the feeling of the tentacles was extremely slippery, and he struggled endlessly.

But when he pushed harder, there was no reaction.

In the rise and contraction of the yin fire, a limited space was opened for Yang Zhao, and when he rubbed his other hand, his fingertips ignited a little blue and blue fire.

In the light of the fire, Yang Zhao saw the prey he had just acquired.

It is a long strip-like creature that cannot be seen as an earthworm or a snake, dark gray, with no head and tail, covered with scales, and a bright red line on its body, which runs through the front and back. His entire body was half-burned by the yin fire through Yang Zhao, and he was already dead.

"It's ...... Bloodshot?"

According to the records of the classics obtained by Yang Zhao in that desperate situation, Dripping Blood is a kind of monster that lives in the depths of the earth, is yin-loving and fire-fearing, highly poisonous, often lives near the pure yin veins and yin orifices, lives by sucking yin qi, and often mixes with another creature.

His mind moved slightly, Yang Zhao's body was on one side, and at the same time, the yin fire swelled, the tongue of fire swallowed, and it rolled among the soil and stones, and there was a little more burnt smell between his noses. He then reached out and pulled something out.

"Sure enough, the blood is not far away, and there will be cold oysters. ”

Between Yang Zhao's fingers was a small insect that had been burned into beads, only the size of a fingertip, the life of this thing was much tougher than a drop of blood, although it had been burned by the yin fire, it wrapped its body in a ball, and used a layer of hard shell to survive.

Yang Zhao was not in a hurry to kill him, but continued to grope in the soil and rocks until he caught a dozen of these small insects, and then put them in the palm of his hand and burned them with yin fire.

In this case, no matter how tough the cold oyster was, it was also roasted at high temperatures, and finally left a few fine ashes in Yang Zhao's palm.

With a light blow, the ashes were sprinkled out, but under the reflection of the firelight, Yang Zhao clearly saw that a few faint points of luminous light, he wiped them in the air, and a few faint lights were all in his palm.

After rubbing a few handfuls, when Yang Zhao's palm was spread out again, a small spar that was not much bigger than the dust particles appeared.

Carefully put his eyes up, observed from multiple angles, and after looking at it for a long time, Yang Zhao finally took a long breath: "Cold oysters eat gas and condense...... Look at this purity, it should be right!"

With the cold oyster as a guide, Yang Zhao no longer had to work hard, and it only took a quarter of an hour to find the source of the Yin Gathering Land.

With just one glance, Yang Zhao understood that at least until now, God was still on his side—otherwise, he wouldn't have found this place so easily.

What catches the eye is a piece of cyan jade, although it is under the nine places, but it is self-generated and misty, and it is a few zhang around it, and it is also natural to open up a vacant land, and the blue light is churning in a small space, overlapping and overlapping, so that the sediment is fog, and the light and shadow are sufficient.

This light mist looked gorgeous to the extreme, but Yang Zhao stood here for a while, and then he saw countless cold worms, crawling towards the light mist, and then evaporating in an instant, like moths to a fire, endlessly.

The earth and rocks around the light mist have clearly been alienated, and it looks full of holes, but it seals the light mist tightly, and the occasional oozing bit will soon be attracted by the surrounding yin qi, blend into the leylines, and go downstream.

Taking a deep breath, Yang Zhao tore off a corner of his robe and cautiously poked into the light mist.

There was no vibration, and the corners of his robe, which were made of fog and pine iron, were silently reduced by half, and there was no time to even be burned.

"Good! Sure enough, it's Nine Shades of Earth!"

Yang Zhao rubbed his hands, feeling a little sweaty in his palms.

Perhaps due to the influence of the jade itself, the purity is not enough, but this must have flowed out of the Nine Shadows Realm, and in the process of flowing, I was attracted by this naturally born jade, so that I could exist in it. (To be continued......)
