Aikai was Aili's admirer, and they were frequent “partners”. Now that Aili had found herself a new lover, how could Aikai accept it? Aikai was stronger than Aili. The moment he attacked, not even Money could react before the pitchfork stabbed into Xiang Shaoyun's body.

During this moment of crisis, Xiang Shaoyun finally decided to no longer stay still and released his Nether Soul Domain. He had recovered considerably and could now use his Nether Soul Domain. In addition to Aikai, all the feathered beastmen in the area were trapped within the Nether Soul Domain.

"You will think a tiger is a cat if it doesn't show its might." This time, Xiang Shaoyun truly intended to kill.

He found that these beastmen couldn't be reasoned with. Only by showing sufficient strength would he be able to restrain them.

Imperial Nether Prison.

Numerous chains shot out from everywhere, attacking all the trapped feathered beastmen. Before the feathered beastmen even realized what was happening, the chains shackled them all.

"What are these? Get away from me!" Aikai roared as he flapped his wings, forming numerous blades that sliced at the chains.

Unfortunately for him, his strength was greatly suppressed in the Nether Soul Domain. Furthermore, the chains were far tougher than anything he had imagined. Those chains had reached a Sovereign's level. How could they break free from them?

"Handsome human, what are you trying to do?" Aili asked in alarm. She was similarly shackled by the chains.

"Nothing much. I just want to kill all of you," said Xiang Shaoyun with a grim tone.

"No, please don't. I don't want to die!" some feathered beastmen started begging.

The beastmen were the same as humans. They had complex emotions, and in such a helpless situation, it was natural for them to plead for leniency. Even Aikai, who was still struggling to break free, became flustered.

"Are you worth sparing?" Xiang Shaoyun questioned in a calm and unruffled manner instead of directly killing them.

"You humans are only here at the Sinister Wind Den for the yin wind grass, right? We know where you can find some!" said Aili.

"Do you?" Xiang Shaoyun questioned.

The feathered beastmen hastily nodded.

"Apart from the yin wind grass, do you have any other good stuff?" Xiang Shaoyun asked after giving it some thought. "Just the yin wind grass alone is not enough for me to spare all of you."

His final sentence frightened some of the beastmen so much they started trembling.

Aikai answered, "Apart from the yin wind grass, we also have yin wind stone. In fact, we took this trip to search for yin wind stones. Those stones can help us increase our wind power."

"Yin wind stone? Is it the stone capable of gathering yin wind?" Xiang Shaoyun asked in excitement.

"That's right. Each time the Yin Wind Devil Face appears, yin wind stones will appear as well. Things should be the same this time," said Aikai.

"Good, that is decent information. I will spare your lives," said Xiang Shaoyun. "However, you may have escaped death, but you still need to be punished. Swallow these poison pills. After you gather yin wind grass and yin wind stones, I will give you the antidote. Otherwise, none of you will live."

He then released them and gave them the poison pills. At that moment, one of them tried to slip away. He was confident that without the Nether Soul Domain, he would be able to escape easily. However, he had only gone a few steps before the Nether Soul Domain swallowed him again. When he reappeared, he was already a corpse.

"You can try escaping if you want," said Xiang Shaoyun toward the others with a sneer.

The range of his Nether Soul Domain was no longer small. Within the distance his senses could reach, killing someone was as easy as flipping his hand. His actions frightened the other feathered beastmen, and they immediately swallowed the poison pills.

They were actual poison pills. Xiang Shaoyun had obtained them from the Emperors he had killed in the past. He had kept them with him and had not gotten any chance to use them.

Now, he could use them to make these feathered beastmen work for him. If he had to personally search for the grass and the stones, it would take a lot of time. If he could actually use the Nether Dragon Soul Headband on them, he wouldn't have to put so much effort into controlling them.

After swallowing the poison pills, they headed off and started working for Xiang Shaoyun unwillingly. Before they left, Xiang Shaoyun warned that if they did not return in seven days with what he wanted, the poison would erupt and they would die.

And thus, Xiang Shaoyun obtained a period of peace. With Money standing guard, he continued to heal himself. After three days, he was finally fully healed. He started studying his surroundings, and he learned that this place was very far from the Sinister Wind Den.

He had not expected that a gust of wind would bring him this far. Some wind elemental plants could be found in the area, but it was too bad their grades were low. The beastmen had probably harvested the high-grade herbs long ago.

After making sure there were no dangers in his surroundings, he entered meditation again instead of roaming around. He was going to increase his wind power and comprehend the profundity of wind.

After witnessing the inhalation and exhalation of that devil face, he had a feeling the profundity of wind was much deeper than what he had originally thought. Speed was not the only aspect of wind. Destruction was also an aspect of it, and it was worth studying.

Xiang Shaoyun tried to empty his mind and comprehend the profundity of wind. But for some reason, the devil face kept appearing in his mind like a vengeful spirit, making it hard for him to stay calm. He kept having a feeling that the face was everywhere in this cultivation zone, and he was unable to calm his mind.

"What was it exactly? They called it the Yin Wind Devil Face. Is that the source of the yin wind?" Xiang Shaoyun wondered.

He then recalled the sight of the beastmen and demonic beasts heading toward the Sinister Wind Den without a care for their lives. Eventually, they were all swallowed by the devil face. They were then spat out in the form of blood. Just from that, it was obvious something terrifying was behind that face.

Xiang Shaoyun was unable to make sense of it, and he sensibly decided to forget about it.

After getting the yin wind grass and the yin wind stones, perhaps he could use them to comprehend the profundity of wind. After two more days, Aikai returned. He was badly injured, his appearance giving Xiang Shaoyun a shock.

"Aikai, what happened?" Xiang Shaoyun asked.

"Dead, all dead," Aikai answered, intense fear plastered all over his face.

"What all dead? Speak clearly!" Xiang Shaoyun said with a frown.
