Before following the zombie lord to break out this battle, the ghost had already killed more than ten level six undead creatures, and at this time, in just ten minutes of battle, the ghost had once again obtained the soul fire of more than twenty level six undead creatures.

In an instant, this highly gifted ghost had the intention of advancing to the seventh level of undead creatures.

Although the ghost knew that if he waited a little longer to advance to the rank seven undead creatures, he would be able to obtain a few more soul fires of the sixth-level undead creatures, but the ghost was also worried that once he waited too long, it would cause the bone dragon lord to retreat, and his hopes would be disappointed.

After all, with his own cooperation, his contract master, the zombie lord, occupies an absolute advantage, and the battlefield is almost one-sided, once after a while, the bone dragon lord does not escape, he will face a dangerous situation of falling.

Therefore, after sensing the surge of his soul fire that was about to advance, the ghost immediately stepped aside and began to fuse and absorb the soul fire of the sixth-level undead creature stored in his body.

With several soul fires, integrated into his own soul, the ghost instantly began to advance to the lord level.

The fluctuation of the promotion spread by the soul fire also became stronger and stronger.

Zhilu Dao, this nasty ghost, was about to be promoted to the lord level, and the bone dragon lord had just had a hint of retreat, and he immediately became firm.

Because, the bone dragon Gregory knew that as his most important cervical vertebrae broke more and more, his injuries became more and more serious, and he was closer to being completely fallen.

Originally, even if the ghost did not advance to the seventh-level lord level, he would not be able to fight for long, and he would have to retreat. At this time, the ghost has been promoted, and he naturally can't continue to stay, otherwise, when the time comes, facing the siege of two lord-level existences, his situation will only be more dangerous.

Of course, for the arrogant and powerful bone dragon Gregory, even if he was besieged by several beings of the same level, he could easily escape as long as he wanted to.

The powerful talent of the dragon clan is not Gaide, not only the normal dragon clan, even after death, the bone dragon that turns into an undead creature also inherits a lot of strong talent of the dragon clan.

As a bone dragon, Gregory mastered the ability to fly as soon as he was born.

For most lord-level beings on the undead plane, less than half are able to master the ability to fly. Except for a few undead creatures with special flying talents, most of these lord-level existences who have mastered the ability to fly off the ground rely on casting a kind of undead flying magic unique to undead creatures - levitation.

However, unlike those undead creatures who are born with the talent for flying, the undead flying magic levitation is not as fast as it can run on the ground.

However, the flying talent of the bone dragon is faster than that of the vast majority of undead creatures of the same level who have the ability to fly, and naturally it is not something that those of the same level who can cast undead magic can catch up.

Among the dozens of undead creatures besieging the Bone Dragon Lord, except for the ghosts, none of them, including the Zombie Lord, had the ability to fly, so it was naturally impossible to leave the Bone Dragon Lord who could fly away.

Because the ghost does not have a physical body, it can perform undead magic, and it has the talent of flying, so it is naturally able to fly. Moreover, when the ghost is at the intermediate level, it has the ability to fly, and once it is promoted to the lord level, the flight speed is not necessarily worse than that of the bone dragon lord.

The extremely high talent has made the ghost have already found the direction of advancing to the lord-level existence before, and now that it has obtained enough soul fire to devour and absorb, it will naturally begin to advance to the lord-level existence in an instant.

In just a few seconds, the ghost had completed the most important step of the undead creature's advancement, the transformation of the soul fire.

For a moment, a sense of control over a tremendous amount of power filled the ghost's mind.

For ghosts, the transformation of the soul fire represents the improvement of spiritual power.

Because, because of the spiritual talent attack magic, as soon as the ghost was promoted to a high-level undead creature, it immediately had the powerful strength of a truly senior seventh-level lord.

"Ghost, you really lived up to my expectations and advanced to become a level 7 undead creature, and now cooperate with me to kill this skeleton. "When the soul fire of the ghost had just completed its transformation, and before it had time to adapt to the powerful power that had increased since the renewal, the command of its contract master came from the soul fire.

Although the owner of his contract, the zombie lord, did not reveal his malice, but the ghost could faintly sense that the zombie lord at this time still had a desire to devour himself, although he covered it up well, but he couldn't hide it from the ghost.

However, the ghost who has been promoted to a lord-level existence will not continue to be a contract servant of the zombie lord, but intends to take this opportunity to get rid of the shackles of the servant contract and restore the free soul fire.

After being promoted to the lord level, the wraith already has the ability to resist the backlash of the servant contract.

After all, the servant contract is a relatively lenient kind of soul contract witnessed by the rules of the undead plane. Only if it is a lord-level existence, even if it encounters a contract backlash, it will not fall directly, at most it will only fall in level. The great drop in strength also gave the contract servants a chance to regain themselves.

You must know that some strict soul-like slavery contracts can even enslave the soul and mind of living beings, so that the enslaved creatures completely lose themselves and everything becomes the owner of the contract. Such contract creatures will not even have the intention of rebelling, and once the owner of the contract falls, they will be directly wiped out under the rules of the slave contract.

At this time, the zombie lord still didn't know that his contract servants already had plans to betray him.

Most of the contract servants, when they first started to advance to the lord level existence, have just gained extremely high wisdom, and when they first crave freedom, they will be immediately killed and devoured by their contract masters. These undead contract creatures don't have the intention of rebelling before they advance to the lord level.

Although the Zombie Lord is the contract master of the ghost, he can only use the servant contract and order his contract servants to do anything, but he cannot sense the thoughts of his contract servants.

At this time, he still had the idea of making himself a contract servant ghost who had advanced himself to a lord-level existence and besieged and killed this bone dragon lord by himself, and then he was devouring the soul fire of the ghost, and he didn't know that he had miscalculated.

At the command of the zombie lord, the ghost immediately drifted towards the bone dragon. After advancing to the lord level, the speed of the ghost increased greatly, and the speed of short-distance movement far exceeded that of its contract master, the zombie lord, and even faster than the bone dragon.

Seeing that the ghost of the existence that had been promoted to the lord level was chasing after him, the bone dragon lord immediately flapped his huge bone wings and prepared to start flying away from here.

Creatures such as skeletons and undead creatures naturally do not fly by the reverberating air currents brought about by the flapping of bone wings. Flapping the bone wings is just an instinctive reaction of the bone dragon when it flies, but the real reason why it can fly is that it casts flying undead magic, which belongs to the flying talent of the bone dragon.

"Great Bone Dragon Lord, I don't want to be your enemy, I had to attack you because of the servant contract before, but at this time I have become a lord-level existence, and I am completely able to fight against the servant contract, so I hope to be able to cooperate with you to deal with this hateful zombie together. Just as the bone dragon Gregory spread his wings and fled, a thought entered the soul of the bone dragon Gregory.

Intelligent, undead creatures are able to communicate with each other through soul fire, and the more powerful the undead creatures, the farther away they can communicate with other undead creatures.

After all the ghosts were promoted to the lord-level existence, they were able to communicate with the souls of undead creatures who were thousands of meters away from them, and they were naturally able to communicate with the Bone Dragon Lord's thoughts that were only a few hundred meters away from them.

"You can work with you, but you're going to use the same mental attack you just used on me to attack that rotting zombie. "The arrogant Bone Dragon Lord Grigory, upon learning of the soul transmission of this abominable ghost, immediately agreed without hesitation and made his own request.

Although the Bone Dragon Lord was arrogant, he was not without wisdom, and he instantly understood that this ghost wanted to use his own strength to break free from the constraints of the servant contract.
