Zheng Dong did not immediately have Ling'er release the one-eyed demon. Instead, he reduced the intensity of the purifying flames, fearing that if he burned the one-eyed demon to death too quickly, he wouldn't be able to get any information.
"If you don't kill me, you can tell me how strong the Night Demon General is?"
The one-eyed demon hesitated for a moment before saying, "The Night Demon General's strength is above mine. He is a Overlord!"
"Compared to the Night Demon General, who is stronger, the Demoness?" Zheng Dong continued to ask.
"This..."
Seeing that the one-eyed demon was reluctant to talk about matters related to the Demoness, Zheng Dong had no choice but to have Ling'er increase the intensity of the purifying flames.
Unable to bear it any longer, the one-eyed demon continued, "The Demoness, she is a True Blood Demon. Of course, her strength is above the Night Demon General's."
True Blood Demon!?
True Blood Demons were further divided into three ranks: King, Emperor, and Supreme.
Supreme True Blood Demons were the strongest bloodline among demons and were destined to become God-tier existences.
However, the one-eyed demon did not know which rank the Demoness's bloodline belonged to.
Zheng Dong frowned.
If the Demoness was an Overlord, he might not be able to obtain the authority to control the relic space from her.
What should he do?
Should he go to the inner city and seek help from the angels, the demons' archenemies?
But angels were not necessarily benevolent.
Zheng Dong couldn't make up his mind for a moment.
He looked at the one-eyed demon and asked again, "Besides the Demoness and the Night Demon General, who else is an Overlord?"
"The Gold Demon General, the Spirit Demon General. We have four Overlords on our side, while the angels only have three: the Saintess, the Light Angel, and the Fire Angel." This time, the one-eyed demon answered readily without hesitation.
Since he had already revealed information about the Demoness, it didn't matter to him whether he said more or less.
Right now, survival was more important.
Of course, if there was an opportunity to kill Zheng Dong, that would be even better.
The one-eyed demon pondered in its heart, but outwardly it appeared completely submissive to Zheng Dong.
Zheng Dong also asked for more information about the Saintess, the Light Angel, and the Fire Angel.
The conclusion was that the Saintess's strength was comparable to the Demoness's, but she had greater control over the relic space, putting the Demoness at a disadvantage in a fight.
The Light Angel and the Fire Angel were both very strong. Together, they were not afraid of the Night Demon General, the Gold Demon General, and the Spirit Demon General.
In addition, the one-eyed demon also mentioned that the strength of the Emperors on both sides was not much different.
The demons had eighteen Emperors, while the angels had seventeen.
As for the one-eyed demon, it was the weakest among the Emperors on the demon side.
Of course, this was all according to the one-eyed demon.
Zheng Dong listened with a skeptical attitude.
After roughly understanding the strength of both sides, Zheng Dong still had a question about the Sinful Lightning.
Unfortunately, the one-eyed demon did not know much about it.
The Sinful Lightning was not controlled by either side. It was like a natural disaster within this relic space. No one could say for sure whose head the Sinful Lightning would strike next.
However, every time the Sinful Lightning erupted, the black mist around the Divine City would become denser.
Prolonged exposure to this black mist would stimulate the evil power within one's body, causing a loss of reason and berserk states.
Even demons like the one-eyed demon were unwilling to be exposed to this black mist for extended periods.
The black mist also hid many monsters that had completely lost their minds.
These monsters might have originally been demons, angels, or other extraordinary creatures. Once they turned into monsters, their strength would surge, making them difficult to kill.
Pure-blooded demons were unwilling to operate outside the city. Only mixed-blooded demons would venture outside the city, but they would return to the city periodically.
The one-eyed demon did not know about the ambush by mixed-blooded demons like the Demon Zombies when Zheng Dong and his group first entered the relic space.
All it knew was that the Demon Zombies were very loyal to the Demoness and only obeyed her orders.
And the one-eyed demon was under the command of the Night Demon General.
It was under the Night Demon General's orders to eliminate the Beast Tamers like Zheng Dong who were teleported here within its responsible area.
Zheng Dong frowned.
Since the Demoness had the Demon Zombies and other mixed-blooded demons ambush them, she must have known they would enter beforehand. What was going on?
To figure all this out, he would probably have to find the Demoness or the Saintess.
"One-eyed demon, what else do you know? If not, I'll send you on your way!" Zheng Dong said.
"Can't you let me go? Do we have to fight to the death?" the one-eyed demon said with a ferocious expression.
"If it were you, would you let such a good opportunity pass? As for fighting to the death..." Zheng Dong said, taking out a medium-sized forbidden bomb and summoning Youyou, releasing the King-tier Hell Bull Head.
This time, the one-eyed demon was completely stunned.
While answering Zheng Dong's questions, it had been accumulating power. If Zheng Dong refused to let it go, it would have taken Zheng Dong with it.
But now, even if it died, it couldn't do anything to Zheng Dong.
"If you let me go, I'll take you to find mythical-tier resources," the one-eyed demon pleaded.
"If there were mythical-tier resources, why wouldn't you use them yourself?" Zheng Dong said dismissively and was about to make a move.
The one-eyed demon hurriedly opened its mouth and spat out a black crystal the size of a fist.
"It's not that I don't use them, it's that I don't dare to take too many."
Zheng Dong did not recognize the black crystal, but the dark elemental spirit beside him became very excited upon seeing it.
At this moment, Mona also struggled to get up from the ground and said, "This... this wouldn't be Dark Marrow Divine Crystal, would it? Such a large piece, its value is probably even higher than an eighth-tier resource."
Dark Marrow Divine Crystal was produced at least after the death of a God-tier dark extraordinary creature and could rapidly increase the strength of dark elemental extraordinary creatures.
The one-eyed demon had also rapidly grown to Emperor-tier because it had obtained the Dark Marrow Divine Crystal.
Zheng Dong was a little surprised that Mona even recognized Dark Marrow Divine Crystal.
He immediately felt that this woman's background was probably not simple.
"Thank you for saving me. If I can get out alive, I will definitely thank you properly. You can let your dark elemental spirit use this Dark Marrow Divine Crystal. Perhaps it can grow to King-tier. However, you are only a high-level Beast Tamer, and you probably can't contract King-tier pets yet," Mona continued.
In the one-eyed demon's grand hall, the one-eyed demon was wrapped in a forest cage. On Zheng Dong's left hand, Ling'er appeared in the form of vines. The dark elemental spirit stood to Zheng Dong's front left, picking up the Dark Marrow Divine Crystal from the ground.
However, without Zheng Dong's permission, the dark elemental spirit did not use the Dark Marrow Divine Crystal. Mona also did not know that the dark elemental spirit was not Zheng Dong's contracted pet, but an elemental spirit condensed by Ling'er.
Youyou, in the form of Taji, sat on Zheng Dong's shoulder. The Hell Bull Head it released blocked Zheng Dong's front right. On Zheng Dong's right hand, he still held a large medium-sized forbidden bomb.
After listening to Mona's words, Zheng Dong communicated with Ling'er about whether to let the dark elemental spirit use the Dark Marrow Divine Crystal.
Ling'er indicated that even if the dark elemental spirit grew to King-tier, it would still be under its control and would not betray it.
This was because the dark elemental spirit was condensed by Ling'er and existed by relying on Ling'er. Without Ling'er, it would also disappear.
Even if the dark elemental spirit grew to Emperor-tier or Overlord-tier in the future, it would be the same.
However, as the dark elemental spirit grew, Ling'er's own strength would also increase. It was unknown if it would break through to King-tier.
Zheng Dong did not hesitate too much and let the dark elemental spirit try.
Immediately, the dark elemental spirit took the Dark Marrow Divine Crystal back to the Dark Elemental Dimension Sea and began to absorb and refine it.
The entire absorption process was very smooth, as if the Dark Marrow Divine Crystal was tailor-made for the dark elemental spirit.
In less than a day, the dark elemental spirit had completely absorbed the Dark Marrow Divine Crystal and fed back into the Dark Elemental Dimension Sea.
This caused the Dark Elemental Dimension Sea to expand by more than ten times, making it larger than other elemental dimension seas.
The dark elemental spirit also grew to King-tier, resembling a pure-blooded demon even more, with a bloodline purity even higher than the one-eyed demon.
Ling'er did not receive much feedback power and did not break through to King-tier.
This was not a bad thing for Zheng Dong.
Seeing the Dark Elemental Dimension Sea expand, Ling'er no longer had to worry about its stability, so it condensed ten more dark elemental spirits.
These ten dark elemental spirits, led by the first dark elemental spirit that had reached King-tier, would also quickly grow to General-tier.
While the dark elemental spirit was absorbing the Dark Marrow Divine Crystal, Zheng Dong also learned from the one-eyed demon about the origin of this Dark Marrow Divine Crystal.
Originally, this relic space was a divine kingdom built by a lower-tier divine angel.
It was invaded by another lower-tier divine demon.
The two sides fought a great battle, and in the end, they annihilated each other.
After countless years, the Demoness and the Saintess were born from their corpses, and the Night Demon General, the Light Angel, and other powerful demons and angels were born from the corpses of their subordinates.
And there were also many extraordinary creatures that were influenced by them and turned into mixed-blooded demons or angels.
Thus, the battle continued to the present.
As for the Dark Marrow Divine Crystal, it was secretly dug up by the one-eyed demon from under the demon mountain formed by the lower-tier divine demon's corpse.
If the Demoness found out, the one-eyed demon would surely die.
This was equivalent to digging up the Demoness's ancestral grave.
In fact, the Demoness simply regarded the demon mountain as her private property and did not want other demons to covy it.
The Demoness herself also used a lot of Dark Marrow Divine Crystal for her cultivation, and she often rewarded Night Demon Generals and other demons with Dark Marrow Divine Crystal.
The one-eyed demon had obtained the Dark Marrow Divine Crystal by chance during a mission, discovering a secret passage into the demon mountain.
But it only dared to refine and absorb it secretly, not daring to be too ostentatious. It had only gone three times, and after growing to Emperor-tier, it had not gone again.
This piqued Zheng Dong's interest.
The Demoness was leading the demons in another battle with the angels in the inner city, so she should not be able to pay attention to the movements of the demon mountain.
What about Mona? How should she be handled?
Mona's pets were all dead. During this day, she had relied on the healing potions she brought to treat herself, and her external injuries had almost healed, but she still looked a bit weak.
Zheng Dong did not want to bring a burden.
Although she had expressed that she would thank Zheng Dong properly after getting out, bringing a burden made it uncertain whether they could get out at all.
Moreover, Zheng Dong preferred tangible things and disliked empty promises.
Mona, however, was very clever.
She took out a Mimic Crystal Stone and said, "Zheng Dong, as long as you save me and get me out, I'll give you this Mimic Crystal Stone. I know that three Mimic Crystal Stones can be used to awaken a mechanical pet. Don't worry, as soon as I get out, I'll give you the other two. My father prepared these for me, and he is a titled legend."
This surprised Zheng Dong a little.
There were not many titled legends in the Northern Feng Kingdom. Each of them held high positions and power, so it was normal for them to obtain Mimic Crystal Stones.
Mona said this for two reasons: first, to show that she could afford Zheng Dong's reward, and second, to show that her father was extraordinary, and it would be troublesome for Zheng Dong if he killed her and took her possessions.
Seeing the Mimic Crystal Stone in Mona's hand, Zheng Dong thought for a moment and said, "I don't do things I'm not sure about. I don't even know if I can get out myself, so how can I take you out? How about this, you stay in the one-eyed demon's palace for now, and I'll come back for you after I find a way out."
Mona immediately felt a sense of danger.
If Zheng Dong was unwilling to take her, and if demons came looking for the one-eyed demon, wouldn't she be doomed?
What should she do?
"How about you let one of your pets protect me until you come back, and then this Mimic Crystal Stone will be yours."
In fact, if this were outside, it would be simple. Mona could enter the relic space within the relic bead.
However, within the relic space, one could not open the relic space inside the relic bead.
Finally, after much consideration, Zheng Dong left behind avatars of himself and his pets, Youyou, and others.
After all, he still really wanted the Mimic Crystal Stone.
This was because Jingjing still needed Mimic Crystal Stones to evolve.
Mona also lowered her demands, no longer insisting on getting out, but only asking Zheng Dong to protect her and help her find other Beast Tamers from the Northern Feng Kingdom.
Afterward, Zheng Dong had the one-eyed demon take him to the demon mountain.
To prevent the one-eyed demon from causing trouble along the way, Zheng Dong had Ling'er release purifying flames to wear down the power the one-eyed demon had just managed to recover.
The demon mountain was not within the city, but it was not far from the Divine City.
There was a passage from the Divine City leading to the demon mountain.
It was unclear what this passage was originally built for, but it seemed to be for setting up a grand formation.
And when that lower-tier divine demon died, its corpse happened to land on this passage, forming the demon mountain.
The backyard of the one-eyed demon's palace happened to lead directly into this passage.
Upon entering the passage, Zheng Dong saw that both sides of the passage were carved with mysterious patterns, and there were many slots for embedding various elemental crystals.
Zheng Dong had the one-eyed demon walk in front, and he followed behind.
Several vines extended from his left hand and wrapped around the one-eyed demon.
If the one-eyed demon moved even slightly, Ling'er would make the vines release purifying flames.
After walking for a long time in the passage, winding and turning, he didn't know how many times he had circled before arriving below the demon mountain.
He saw that the passage ahead was collapsed by the demon mountain.
And on the demon mountain, the one-eyed demon had also dug out a mine shaft.
In order to obtain the Dark Marrow Divine Crystal, the one-eyed demon was also very determined, digging hundreds of meters by itself.
The demon mountain was not easy to dig, and the surrounding rocks were very hard.
Zheng Dong did not rush to dig for Dark Marrow Divine Crystal.
He summoned Xiao Zi.
How could treasure hunting be without Xiao Zi?
Xiao Zi was very excited as soon as it came out.
"Master, this is simply a treasure mountain! I feel like there are vast amounts of God-tier resources beckoning to me."
"Don't get excited, hurry and find out how to dig."
Xiao Zi confirmed the direction for mining. Zheng Dong had Youyou release the Hell Bull Head and the Skeleton General, two undead puppets, to start mining along with the one-eyed demon.
