"Hmm!" Looking at the performance of the little skeleton, Obsidian was very satisfied, it seems that he still has his heart set on the demons!"Demon skeletons, demons first and then skeletons, you will definitely be the first demon in everything in the future! Even if you become an undead, you don't have to fall into the reputation of the demons!"

"Your Highness put it down, I care about the demon clan, so I naturally respect you!" the demon corpse returned respectfully.

"Very good! It just so happens that His Highness is also unfamiliar with life here, and he needs the help of a demon skeleton like you very much!" Seeing him so superior, Obsidian looked at him with a smile on his face.

The demon skeleton immediately knelt down on one knee and pledged allegiance to Obsidian: "I am willing to be the forefoot of His Highness and sweep away all obstacles in the way ahead!"

"Haha! Don't worry! Wait for His Highness to ascend to the throne of the Demon Emperor! You are the master of the abyss of the undead! It's time for the abyss of the dead to return to the embrace of darkness!" Obsidian looked at this bone body, which was not much shorter than himself even if he knelt on the ground, and laughed happily, and did not hesitate to reward himself, and drew a big pie for the little skeleton!

The little devil is the little devil, although he has been transformed into an undead, his wisdom has not been improved in the slightest! The demon skeleton listened to Obsidian's words, and his simple heart was very excited! His Royal Highness the Emperor promised himself the position of the Lord of the Abyss, didn't he say that only His Royal Highness the Emperor inherited the throne of the Demon Emperor, and he was the Great Lord of the Abyss of the Undead?

The naïve little devil, too pitiful? He thought that the throne of the Demon Emperor had been passed down from generation to generation! Thinking that the Great Lord of the Abyss was appointed by the Demon Emperor, the trembling bones did not hide the excitement in his heart, and the demon corpse bowed down deeply, and his attitude was humble and pious to the extreme.

"I am willing to be loyal to His Highness!

"Really?" obsidian asked him softly,

Although the demon remains were a little wise, they could see the situation in front of them clearly, and replied without hesitation: "Dare not die?"

"Good!" Obsidian was very happy, "In that case, you are willing to accept the dark mark of Your Highness and protect and be loyal to me forever!"

The demon skeleton glanced up at Obsidian, knocked his chest hard with his right hand, and said, "Yes!"

Obsidian nodded with satisfaction, although the demon skeleton swore allegiance to him, but he was very disdainful of this method in his heart, how could verbal words be as powerful as the control of life and death?

Obsidian directly forced out a drop of blood with his left hand, using blood as ink and fingers as pens, directly carved a magic pattern in the void, borrowing the rules to directly form a slavery rune! Forcing the rune into the iron black bone body of the demon remains, watching the blood pattern spread to the entire body of his body, in the center of his eyebrow bone, a black sun mark faintly appeared, and Obsidian was relieved. However, his right index finger was pale and weak, but it was also trembling!

The demon skeleton only felt that the blood-colored rune was submerged into his bone body, and even directly fed back into the soul fire with the help of the bone body, but he felt as if he was bound by something, but this feeling was only fleeting, but he felt that his connection with obsidian was tightened......

"With blood as a medium, form the most intimate bond. Obsidian explained to him, "The Dark Mark is a special rune formed by the rules of my soul's invocation, and with him, you are my closest guardian. You will give me strength, and my strength will bless you. ”

As Obsidian slowly spat out the words, his spirit gradually recovered, and his index finger was full of blood again, but because the power of the demon remains was far inferior to Obsidian, the effect was not so obvious. However, the feeling of the demon remains is very strong, as if his power has been stolen, and the soul fire seems to be extinguished!

Seeing his situation, Obsidian knew that this was due to the fact that he was not a lord, although he reluctantly used the power of the bloodline to exert the power of the rules, but it caused the weakness of the qi and blood, and the power of the demon skeleton began to feed back to him under the traction of the rules.

And this kind of power feedback usually only happens when he advances, but now it happened in advance, which makes Obsidian feel bad, and the hands he just had just now won't die because of his carelessness. Looking at the soul crystals everywhere, Obsidian shouted, "Hurry!

Listening to Obsidian's words, the demon remains took action, and the soul power was weakened, which could only be made up for by refining the soul crystal. In front of Obsidian, the demon remains were not hidden, and directly manifested the soul fire to search for and refine the soul crystal on this battlefield. As the soul crystals were refined, and the soul power was integrated into his soul fire, his soul fire gradually returned to normal, and he was heading towards the seventh order!

The root of the undead is soul fire, and the bone body only exists as a carrier of soul fire, and it is also a means for them to defend themselves. Their advancement only needs to increase the level of soul fire, and they will naturally be able to advance successfully, and feedback to refine their bones and improve their strength.

To see that the soul fire of the demon skeleton has advanced to the seventh order, obsidian hurriedly took out the soul crystals he had obtained before, after all, only if the demon skeleton advances successfully, he will also get benefits. And the soul crystal in his own hands, it really won't play a role for a while. After all, it is risky to use it to temper the will, so it is better to leave it to him.

After Obsidian used up all the soul crystals he had accumulated, the soul fire of the demon skeleton finally turned cyan, and his bones were also glowing with jade. As for Obsidian, the power of the demon remains transformed into a seventh-order undead spirit was fed back to him, which only allowed his spiritual power to expand by a small circle.

The demon skeleton knew what was the reason why he was able to successfully advance to the seventh-order undead this time, so he directly prostrated on the ground: "Thank you Your Highness for the grace of recreation!

"Well, okay. Obsidian gently lifted him up, "You have accepted my mark, and you are my person." Hurry up, there's still something important to do!"

The demon skeleton got up from the ground respectfully, but found that he was a lot taller than obsidian, but he was a little hesitant.

Obsidian smiled easily: "Haha, it is worthy of my dark knight, it is really tall and mighty!"

"Demon Skeleton, why am I so close to your undead that it won't take long for me to meet us?"

"Your Highness, your huge and vigorous qi and blood are as dazzling as the sun in the darkness in this sea of bones, and naturally it can attract countless undead!" the demon skeleton explained. "You can only hide your own qi and blood so that you don't attract attention. ”

"I see! Your Highness still thinks how popular he is!" Obsidian suddenly realized, and then a faint black mist gradually swallowed his body, "What about this?"

"Your Highness is really talented!

Obsidian was a little surprised, this imperfect guy just learned to pat himself on the back as soon as he was promoted to a high-level undead?
