In terms of geographical location, the Ming Dynasty is located in the south of the Agni Dynasty, and when Changshan went straight south from the Daewoo Dynasty into the Ming Dynasty, the first city it passed through was Xichang City, which was located in the southwest corner of the Ming Dynasty, which was closest to the border.

Chang Shan was not familiar with the geography of the Ming Dynasty, but from the direction, he also knew that if he wanted to return to the area where the Earth Spirit Sect and Qiping Mountain were located, he should go to the southeast.

After entering Xichang City and having a big meal, and resting for a day, Changshan hurried towards the southeast.

After three days of travel to the southeast, Tsuneyama stopped in the middle of a very desolate mountain range.

The dozen or so mountains in the outer layer of this mountain range are very ordinary, but the middle one is located in the middle of nine mountains of similar size, which is a standard Jiuyang Suoyin Mountain.

Nine is the extreme, Jiuyang Suoyin Mountain is also the Xuanyin Mountain that the world often says.

The yin qi in Xuanyin Mountain is not necessarily richer than the yin qi in the Five Elements Lock Yin Mountain, however, in terms of the purity of the yin qi, the yin qi in Xuanyin Mountain is much purer than the yin qi in the Five Elements Lock Yin Mountain.

Yin Qi is pure, if there is Yin Ore in the mountains, then the quality of Yin Ore must be good.

There is a lesson from the past, Chang Shan didn't plan to do anything before taking revenge, but he left directly without investigating this Xuanyin Mountain, but he was a little unwilling in his heart.

"If this place is just an ordinary Xuanyin Mountain, then go to the top of the mountain and investigate. Anyway, this mountain is not big, and it won't take long to investigate. ”

Thinking about it, Chang Shan summoned his bone wings and flew into the air to observe the entire mountain.

Chang Shan observed the situation of the entire mountain and found that in the entire mountain, except for the mountain under him, the rest of the mountains were not distributed in a trace of regularity, and the mountain under him was just the most ordinary Xuanyin Mountain.

"The yin qi of this Xuanyin Mountain is not as strong as the yin qi in the Five Elements Lock Yin Mountain that I have seen before, and there should be no danger in the mountain. ”

Chang Shan pondered for a moment, and then flew directly to Xuanyin Mountain.

This Xuanyin Mountain is less than 100 zhang high, and its length and width are only more than 200 zhang, and there are no trees on the top of the mountain, only a few low bushes.

Although Chang Shan had already formed a soul bead, it was still not an easy task for him to use the power of the Yuan God to explore the underground ore veins. Therefore, he observed the entire Xuanyin Mountain with the naked eye, and then looked for the caves in the mountain, hoping to determine whether there was Yin ore in the mountain through those caves.

Chang Shan searched the entire Xuanyin Mountain, and found the deepest hole that was less than two zhang deep.

Unable to take advantage of it, Chang Shan could only slowly explore the entire mountain with the power of the primordial gods.

After exploring for a long time with the power of the Yuan Shen, Chang Shan did not find the Yin Mine he was looking for, but found something strange in the center of Xuanyin Mountain.

Chang Shan didn't know what he had found, but the yin qi emitted by that thing was very pure and very strong.

"That thing definitely won't be a living thing, otherwise, I've been observing it with the power of the primordial god for so long, and it will definitely fight back. ”

After pondering for a moment, Tsuneyama decided that there would be no danger and decided to figure out what that thing was.

"Let's see if there's a natural cavern around that thing!"

Chang Shan just tried it casually, he didn't want to, he used the power of the Yuan Shen to observe around that thing for a while, and really found a space that was enough for him to stay.

That space was more than sixty zhang away from where he was, Chang Shan hesitated for a moment, then took out the earth escape charm and used the earth escape technique to escape inside.

Chang Shan only felt that his body was heavy and light, and he came to a place where the yin qi was extremely strong.

Separated by more than sixty feet of earth and rocks, although Chang Shan sensed the existence of this space, he could not clearly observe this space. At this time, he was deep in this space, and he realized that this space was not a natural stone cave, but a stone chamber dug by people.

Chang Shan frowned, glanced around, hesitated for a moment, and walked to the door of this stone room.

Out of the stone room, Changshan came to a narrow passage with eight closed stone gates on both sides of the passage.

Chang Shan walked to a stone doorway, looked inside, and the power of the primordial god passed through a shield composed entirely of yin qi, and observed a small stone room.

There was only one stone bed in the stone room, and there was a person lying on the stone bed, and there was no trace of vitality in this person's body, but several kinds of dead energy.

"Zombies!"

Chang Shan was slightly startled in his heart, and investigated the other seven stone chambers at a very fast speed, and found that there was also a zombie in each of the other seven stone chambers.

Obviously, this is a corpse cave where zombies are raised.

"Who is cultivating these zombies? Is this the sect known for controlling zombies?"

Chang Shan pondered for a moment, and then began to think about what he should do with these zombies.

Although Changshan himself is also a zombie, however, his experience as a teenager made him not have any good feelings for zombies. He had the idea of destroying these zombies in his heart, but when the picture of these zombies being burned appeared in his mind, a sense of sadness appeared in his heart.

"If these eight zombies are really stiff, they will become zombies, and they must have great resentment, and they are all pitiful people, and if they are bitten by zombies and become zombies, they are also pitiful people. Should I really destroy them? But if I don't destroy them, and they go out and bite people, won't they turn more people into zombies?"

Thinking of the fact that the village was destroyed by zombies back then, Chang Shan hesitated for a while and decided to destroy the eight zombies.

"These eight zombies are most likely a sect known for controlling zombies, and it is better to free them from being refined into puppets than to let them be refined. ”

Chang Shan muttered to himself, and then raised his hand to push the stone door in front of him.

When Chang Shan observed the stone chamber just now, he didn't find any formations, but after his hand was placed on the stone door, a layer of black protective formation appeared on the stone door.

This layer of protective formation not only removed Chang Shan's thrust, but also infused a very pure Yin and Cold Qi into Chang Shan's body.

In a moment, Changshan was frozen in place.

At the moment when Chang Shan was frozen in place, in the narrow passage where he was, a large number of yin spirits suddenly appeared on the wall. There are thousands of these ghosts, most of them are animal spirits, but there are also some human spirits.

As soon as many yin spirits appeared, they rushed towards Chang Shan together, and submerged into Chang Shan's body in a moment.

Chang Shan was horrified in his heart, and he didn't have time to think about it, so he used the power of the Yuan Shen to contact the Ten Thousand Ghost Banners, and controlled the Ten Thousand Ghost Banners to devour the Yin Soul that invaded his body.

There are thousands of yin souls that have invaded Chang Shan's body, and although Wan Ki Banner restrains the yin spirits, he can't collect all the yin spirits in a short period of time.

After most of the yin spirits entered Chang Shan's body, they all drilled into Chang Shan's sea of knowledge and attacked Chang Shan's primordial spirit.

When these Yin Spirits attacked Chang Shan's Yuan Shen, Chang Shan discovered that the layer of blue brilliance on the surface of his Yuan Shen actually had the effect of protecting his Yuan Shen.

There are nearly three thousand Yin Souls who have entered Changshan's Sea of Knowledge, but the attacks of these Yin Spirits are not consistent, and they can't hurt Changshan's Yuan Shen at all.

The Ten Thousand Ghost Banner is a magic weapon that can evolve, and the more Yin Spirits it devours, the more powerful it becomes.

After devouring the Yin Soul in front of him, the Ten Thousand Ghost Banner, which had greatly increased its power, devoured the Yin Soul that had invaded Changshan Zhihai in less than a stick of incense.

The quality of the Ten Thousand Ghost Banners refined by Chang Shan is not bad, but after devouring thousands of Yin Souls at one time, the Ten Thousand Ghost Banners still can't suppress the Yin Ghosts in it.

Feeling that the primordial spirit of the ghost fox that he had originally taken in was attacking the Huangquan Yin Mansion Great Array, Chang Shan's eyes flashed with cold light, and he didn't hurry to dissolve the cold qi on his body, and tempered the Ten Thousand Ghost Banners with soul fire.

On top of the refining of Changshan's soul fire, the quality of the Ten Thousand Ghost Banners has improved a little, and the power of the Huangquan Yin Mansion Great Array has also increased a little.

The ghost fox felt that he could not break out of the Huangquan Hell Array, so he stopped resisting.

After stopping resisting, the ghost fox still did not settle down, devouring the other ghosts in the Ten Thousand Ghost Banners.

"If you use it against the enemy at this time, the yin spirits inside will definitely not cooperate, no wonder there is a saying in the "Soul Sutra" that ten thousand ghost flags need to be tempered a thousand times before they can be used freely. ”

Thinking about it, Chang Shan urged the soul refining array to refine the ghost fox, and then used the soul fire to refine the ten thousand ghost flags.

Half an hour later, when the ghost fox was separated, Chang Shan found that most of the yin souls collected by the ten thousand ghost flags had been devoured by the ghost fox, and there was not a single human yin soul left.

With a frown, Chang Shan then used the soul refining array to refine the ghost fox.

It wasn't until he refined most of the yin qi in the ghost fox's body into the Ten Thousand Ghost Flags that Chang Shan stopped refining the ghost fox.

After eliminating the Yin Soul of the Ten Thousand Ghost Banners, Chang Shan began to refine the Yin and Cold Qi in his body. With the help of the blood of the spirit beast, it took Chang Shan less than half an hour to dissolve the cold qi in his body.

Glancing at the eight stone gates, Chang Shan sighed and took out the earth escape talisman. After Chang Shan urged the earth escape talisman, the yellow light on his body flashed, and he disappeared in place.

When he got outside, Chang Shan didn't think much about it, and left Xuanyin Mountain directly.

Out of the mountain where Xuanyin Mountain is located, Chang Shan stopped in a hidden place and recovered the power of the Yuan Shen.

Chang Shan tempered the Ten Thousand Ghost Flags, and consumed a lot of the power of the Yuan Shen, and it took him ten days to restore the power of the Yuan Shen to its peak state.

Opening his eyes, Chang Shan just wanted to get up and stood up, his brows furrowed.

"Why is there a little tightness in your chest?"

As soon as this thought appeared in Chang Shan's heart, he coughed violently.

Since entering the cultivation realm, Chang Shan has never been sick, and he never thought that he would cough again one day. But now, he couldn't suppress the thought of coughing, and could only keep coughing violently.

Chang Shan coughed while concentrating on the situation in his body, and after a while, he understood the reason for his violent cough.

In Chang Shan's right chest, there was an extremely cold xenomorph spiritual power among several meridians, and this xenomorphic spiritual power was pulling a very uncomfortable area around his chest, and only coughing could relieve that uncomfortable feeling, so he couldn't help coughing violently.

"I didn't even melt all the cold qi in my body just now!"

Chang Shan's brows furrowed slightly, and he forcibly pressed down the uncomfortable feeling in his chest, and the true yuan was used to refine the yin qi.
