After walking for a long time, the two finally walked to the gate of Qingfengyuan in the center of the city.

Zhuang Yu looked at the place where he was attacked and pierced his belly with some emotion, his eyes slightly different.

After so many years, he didn't know who the person who attacked him was.

The retreat of Qingfeng Garden is still built with a black stone architectural style, and some purple wood is exposed from time to time.

The entire Qingfeng Garden tall building was shining with colorful inspiration, which was somewhat inconsistent with the black stones.

After a moment, Chen Qinghan walked over slowly.

Just as she was about to say something, a token on her waist suddenly flashed.

Chen Qinghan took the token in surprise and put it in front of her eyes and looked at it, with a red light flashing in her eyes.

She frowned for a moment.

"Sister Han, what's wrong?" Yun Ling'er was a little surprised.

"The Deacon Hall sent a message. Something happened to the Ming Tomb just before, and there was another abnormal movement in the formation just now!"

Zhuang Yu frowned and suddenly said, "Why don't we go directly to find it? There should be specific information about the Deacon Hall in it?"

Chen Qinghan nodded after hearing Zhuang Yu's words.

"Okay, news came from the Deacon Hall that someone had fought near the ancient battlefield, killing several spiritual vein-stage cultivators in succession, and were chased by the law enforcement elders of Gu Feng City. At this moment, they had fled to the area of ​​the Nether Tomb!"

Chen Qinghan explained to Zhuang Yu and Yun Ling'er as she walked.

Yun Ling'er was a little surprised and said, "Aren't the Ming Tomb guarded by the people of Gu Feng City? How dare you run to where?"

Zhuang Yu also looked surprised.

After a while, the three of them rushed out of the gate of Gufeng City.

Soon, the flying boat buzzed and flew towards the south.

In less than an hour, Chen Qinghan had already activated the flying boat to the vicinity of the Black Water River.

After walking out of the flying boat, Zhuang Yu looked at a black water river in front of him, looking surprised.

The air around was still the same as before, with a light black gas everywhere, looking gray.

The river water has cut off, leaving only mines of different sizes, with many black stones piled up at the entrances.

The three of them were about to go forward to check the entrances of the mines, and a ray of light flew down from the air.

The escape light dissipated, and a guardian in armor appeared.

The guard felt the spiritual power and momentum of Yun Ling'er's body and immediately became respectful.

"Senior, this mine vein had some accidents a few days ago. From tomorrow, a master of formation will come to completely seal this mine vein. I will leave you here to inform the monks who are coming to mining!"

When Chen Qinghan saw the guard appear, she didn't wait until she finished speaking, she handed him the prepared green token in her hand.

"We received the task commission from the Deacon Hall and were looking for this person. It is said that he escaped here. We wanted to go in and see, what happened? "

After seeing Chen Qinghan's token, the guard's nervous expression eased a little, and then respectfully returned the token to Chen Qinghan.

"It's such a senior sister. You should have heard of it here. Although a small earth fire sand ore vein was discovered, it is also a dark tomb for the cultivators of the Nether Ghost Sect. Although it had been abandoned for hundreds of years when it was discovered, there were still many ghosts infected by demonic energy inside, and they were then removed by all the elders of the Deacon Hall of Gufeng City!"

"Who knew that during the mining of earth fire sand last month, three skeleton demon pets at the peak of the spiritual vein stage suddenly appeared in the deepest part. Then a large number of enhanced ghosts completely infected by demonic energy continued to emerge from the deep part. There were countless. Although the Deacon Hall sent people to kill the demon pet in time, those ghosts were like endless. After that, the elders of the Deacon Hall ordered the place to be completely sealed, and the monks who came to mining were just expelled today!"

The guard said respectfully, Chen Qinghan listened and frowned.

"So, can we go in and check it out?"

"Yes, senior sister, you have the spiritual guide from the Deacon Hall, you can pass at will, but the demonic energy inside is a bit weird. Please be careful. As soon as there is an abnormality, you can get out immediately. More than ten spiritual veins in our guard team have disappeared inexplicably when they are setting up the formation base!"

The guard said this, a hint of fear appeared on his face, and then he moved his wrist and handed Chen Qinghan a jade slip.

"This was discovered when our guards set up the formation base. It is a relatively familiar and safe route. Senior sister, you can give a brief reference!"

"So, thank you, let's go in and check it out!"

After Chen Qinghan finished speaking, she put away the jade slip and walked towards a mine cave.

The guard looked at Zhuang Yu and the other two who disappeared outside a cave entrance, shook their heads, turned around and flew into the air.

"Zhuang Yu, you know a little about ghost pets, what do you think?"

Chen Qinghan asked Zhuang Yu while looking at the route inside the jade slip.

"The refining of ghost pets must require a ghost pool with extremely strong ghost power. The demon pet is no exception. At least it needs a place where the demonic energy gathers itself or is condensed with great magical powers to condense and refine it with acquired powers. Demon energy is more difficult to control than ghost energy. An important purpose of earth fire sand is to seal the demonic energy. If the earth fire sand ore veins here are slightly transformed and utilized, it is a good demonic energy gathering formation!"

"Then, use some extremely powerful magic weapons at the core of the ore vein to slowly develop a magic pool. This is a conventional refining method similar to the ghost pool. However, this method takes too long and it takes more than a hundred years to nurture it. In addition to the time and energy required to refine the magic pet, countless spirits of ghosts are needed as materials. Such methods can only be supported by at least one medium and large sect!"

Zhuang Yu shook his head and said while exploring the situation around him.

"If you really need a magic pool, it may not be possible!"

Chen Qinghan was originally looking at the jade slip attentively, but when she heard Zhuang Yu's last sigh, she suddenly frowned.

"Sister Han, you?" Yun Ling'er glanced at Chen Qinghan with some surprise.

"A long time ago, a branch of the Nether Ghost Sect fled to the southern country. Senior Brother Qingmu was ordered to come and clear it out. He said that at that time, the Demon Cultivation line of the Nether Ghost Sect had a treasure that could be refined into the treasure. You can choose a location to relocate it at any time. Although it still takes a lot of time and energy, it is much faster than finding the mineral veins to breed the Demon Pool!"

After Chen Qinghan finished speaking, Zhuang Yu suddenly remembered Mingfengzhu and muttered in his heart.

Just as he was about to say something, he suddenly thought of it, and a purple light flashed slightly on his body, and a faint purple film enveloped it.

In an instant, the faint black demonic aura floating around began to move closer to the purple membrane on Zhuang Yu's body.

As soon as the demonic energy touched the purple light film, it actually turned with the spiritual power flowing in the purple film. Before it could turn, it had completely turned into purple spiritual power.

Chen Qinghan and Yun Ling'er both stared at Zhuang Yu with wide eyes.
