From this, one could see how powerful the Black Heaven Race was.
And today, he finally saw cultivators of the Black Heaven Race.
A total of four Black Heaven cultivators were sent to Area C.
Their appearances were different from humans.
The members of the Black Heaven Race were a little small and skinny, about the same height as a twelve or thirteen-year-old human child.
Their entire body was gray, their head was very large, and they had no eyelids, as though they would never close their eyes.
Moreover, their eyes were large and pitch-black.
Their hair was like spikes standing on end like weapons.
Even on the dim 90th floor, there was a faint sharp glow emitted from these hair.
Right now, their bodies were covered in multiple layers of chains and their expressions were extremely dejected. Their bodies were riddled with torture wounds, so severe that their bones were visible.
Long black needles engraved with countless tiny runes were pierced into their heads.
While Xu Qing was observing them, the Sword Holders who escorted the Black Heaven Race prisoners completed the handover process with Ghost Hand. After noticing Xu Qing's gaze, Ghost Hand glanced at the four Black Heaven Race members and killing intent appeared in his eyes.
"The Black Heaven Race is rare in our Fenghai County."
As he spoke, he called out to the Pawns in Area C beside him and asked them to escort three Black Heaven cultivators into the small world.
When those Pawns from Area C looked at the Black Heaven Race, they revealed sinister smiles and there was even a savage glint in their eyes. Clearly, to them, such a rare item must be very fun.
"Remember not to kill them. Keep them for future people to practice with. Don't hog them all to yourself." Ghost Hand scolded. The Pawns didn't mind. They laughed and left with the three Black Heaven people.
Very soon, only Xu Qing, Ghost Hand, and a Black Heaven member were left on the 90th floor.
"Come, Xu Qing. The lesson during the secret training was lacking specimens. Let's continue your lesson today."
Ghost Hand licked his lips and looked at the dying Black Heaven. He walked over with a sinister smile and lifted him up.
"The Black Heaven Race doesn't like sunlight. This is their fatal flaw. However, don't be deceived by this saying. This doesn't mean that they can't withstand the light at all. After all, there's a moon in the Black Heaven Race."
"In reality, the sunlight must be extremely dense for it to be fatal; otherwise, it will at most make them uncomfortable."
Ghost Hand's eyes were filled with cruelty as he explained to Xu Qing in detail.
"Pay attention to the eyes of the Black Heaven Race. Countless imprints have gathered there. Most of the cultivation methods of the Black Heaven Race are related to the eyes. They are best at enslavement art."
As he spoke, he grabbed the right eye of the Black Heaven cultivator. Amidst its mournful cries, he dug out its eyeball.
As black blood splattered everywhere, Ghost Hand threw the eyeball to Xu Qing.
Xu Qing calmly caught the eyeball. After observing it carefully, he clearly saw countless runes in the black eyeball. They were densely packed, as though they were arranged into some kind of array formation.
"This thing can be used as a magic artifact. I'll give it to you as a souvenir."
Xu Qing knew that this item was definitely precious. He expressed his gratitude by bowing and cupping his fists, and carefully kept the eyeball.
"It's precisely because the Black Heaven Race's cultivation and talent are special that the divine sense of the Black Heaven Race's cultivators is ranked at the top even among the myriad races. Their divine sense is so strong that it can kill without leaving a trace, control all things, and enslave countless races."
"As for the experts of the Black Heaven Race, they can materialize things out of nothing."
Ghost Hand continued to poke around the Black Heaven Race cultivator in his hand and introduced it to Xu Qing in detail.
"Due to this, there will be brain crystals in the brains of the Black Heaven Race. Their value is even greater."
"The brain crystal is also the key for cultivators of this race to absorb anomalous substances and use them for cultivation. There were once humans who took it out and tried to fuse it into their bodies, but they all failed."
"What I'm saying is only the foundation power of this race. Black Heaven Race is extremely huge, so there are many sects and families inside with countless paths and spells of all kinds."
"In addition, there's their hair. This is also the most basic weapon of the Black Heaven Race. It contains poison that can dim and extinguish souls. If you encounter them in the future, you have to be careful."
Ghost Hand was about to continue when Xu Qing hesitated for a moment before speaking softly.
"Senior, can you give me a strand as a memento?"
Ghost Hand laughed. He directly broke off three of the Black Heaven Race's hair spikes and threw them to Xu Qing. After that, he continued to explain the Black Heaven Race to Xu Qing.
Towards the end, he simply spoke while dissecting the Black Heaven Race cultivator.
Xu Qing's expression didn't change from the start until the end. He didn't have any pity because he knew that if he was captured by the Black Heaven Race, there was a high chance that the same thing would happen to him.
The mortal feud between the two races was known by everyone in Wanggu.
However, he felt that this time, Senior Ghost Hand didn't seem to be teaching a lesson. Instead, he seemed to be using the lesson as an excuse to satisfy his hobby.
However, Xu Qing pretended not to see it and listened very carefully.
Just like that, two hours later, under Ghost Hand's unsatisfied gaze, the lesson ended.
"It's a pity that there are too few specimens. I'll explain it to you properly next time." Ghost Hand licked his lips and took out a wine flask to take a big gulp. He hummed a small tune happily and walked into the small world.
There were no longer four Black Heaven cultivators in Area C but three.
Xu Qing cupped his fists and bowed, watching as the other party left.
