The fluctuation of Locke's soul fire transformation and promotion was fully emanating from hundreds of meters away, and the undead creatures on both sides around Locke knew that there was another undead creature on the battlefield who had been promoted to the third level of undead creatures.

However, in a short period of time, there is not only one undead creature that has advanced on the battlefield, but more than a dozen, and most of the undead creatures have been promoted from level three to level four, or level four to level five. Locke was promoted from level 2 to level 3, and he couldn't attract the attention of these undead creatures at all.

After being promoted to a third-level undead creature, Locke's overall combat power increased a little again. The most obvious improvement is that Locke's spellcasting ability has been greatly enhanced, and the bone spear shooting magic he casts is not only more powerful, but also has more shots at a time, and the number of bone spear shots that can be cast has also increased a lot.

Of course, because Locke's original melee combat power was not weaker than that of a fourth-level skeleton warrior, this time there was no improvement in the strength of Locke's body bones, and the increase in speed was also minimal.

After the soul fire metamorphosed, the surging sensation also disappeared.

For ordinary skeleton creatures, after being promoted, the strength of the bones of the body will not increase instantaneously in a short period of time. Instead, driven by the soul fire, he uses the power of the undead to refine the bones and increase the strength of the bones, so that the strength of the bones is equivalent to their own level.

Of course, in the undead plane, there is enough undead power, and after these undead creatures are promoted, it does not take long to use the power of the undead to temper the strength of the body, and a few days are usually enough.

And because of Locke's cultivation of bone alchemy, Locke's bone strength originally exceeded the level, and he didn't need time to use the power of the undead to temper and improve his bone strength. Moreover, even if Locke uses the power of the undead to temper it, his strength will not increase in the slightest, and may even decrease.

Therefore, after the promotion, Locke also does not need time to temper the strength of his bones.

Bone alchemy is able to refine powerful bones into essence to increase bone strength. So that as long as Locke finds stronger bones, he can improve his strength. As for other undead creatures, without bone alchemy, even if they get the bones of other powerful existences, it is impossible to increase their combat power by replacing their own bones.

Because the replaced bones do not fit into their own bodies, they need to be tempered by their own undead power to make them contract the body, and while using the power of the undead to temper them, the bone essence in the replaced powerful bones will also be transformed into the power of the undead and pass away, and eventually become a bone with the same hardness as the undead creature's own bones.

After advancing to the third level of undead creatures, Locke's soul fire had increased considerably, and he was already able to sense the situation within fifty meters of his surroundings.

At this time, the soul fire that devoured the third-level undead creatures had a much smaller effect on Locke's soul fire.

In Locke's Soul Fire Perception, there were no intermediate undead creatures above level four around, only hundreds of second- and third-level undead creatures.

Because these undead creatures are all contract servants between two lord-level beings, even if the battlefield is disorderly and chaotic, the division between the two camps is very transparent, and any undead creature on the battlefield can easily distinguish between friend and foe.

Among the hundreds of undead creatures, nearly a hundred are third-level undead creatures, and there are only dozens of second-level undead creatures. Most of the third-level undead creatures are on the opposing side, and most of the second-level undead creatures are also on Locke's side.

As time passed, the number of second-level undead creatures on the battlefield decreased at an extremely rapid rate.

Locke immediately slew towards the nearest third-level skeleton creature in his soul perception.

Although the soul fire of a few third-level undead creatures is not much for Locke, no matter how small the mosquito's legs are, they are also meat, as long as they can improve their soul fire, Locke will also kill and devour them, and there are hundreds of third-level undead creatures on the battlefield, which is enough for Locke's soul fire to increase his level.

Among the undead planes, skeleton creatures belong to the largest number of undead creatures, and they are also ordinary undead creatures with generally low combat power. Level 3 skeleton creatures are also the easiest for Locke to kill.

Around Locke, the number of second- and third-level undead creatures was constantly decreasing.

Almost every minute, two or three third-level undead creatures were easily slashed by Locke and devoured the soul fire.

A few minutes passed, and Locke went on to slay more than a dozen third-level undead creatures, devouring the soul fire of these third-level undead creatures.

At this time, in Locke's perception, there were already all third-level undead creatures around. The second-level undead creatures on their own side, including the second-level skeleton warriors who were saved by Locke before, have all been quickly killed under the attack of the enemy's stronger third-level undead creatures.

More than a dozen third-level undead creatures on their own side were also besieged by beings of the same level who were several times their own.

Under the attack of a party of the same level that was several times their own, no accidents occurred, and these third-level undead creatures had no hope of continuing to exist at all.

Even Locke was besieged by nearly a dozen beings of his kind.

Unlike other third-level undead creatures on his side, Locke had an absolute advantage in battle, even if he faced the siege of many existences of the same level.

During the battle, Locke continued to use the only undead attack magic bone spear he mastered.

Although the first-level undead magic alone can't hurt these third-level undead creatures at all, once combined with Locke's terrifying hand-to-hand combat ability, it can completely crush these third-level undead creatures.

The bone spear shot can easily restrain the attack of these third-level undead creatures. In the face of an attack from Locke, even if it was just a bone spear, these third-level undead creatures would instinctively dodge.

Because he can consume the soul fire of these undead creatures from time to time to replenish the mental power consumed by casting the undead attack magic, Locke does not have to worry about the consumption of mental power.

And the attacks of these third-level undead creatures, as long as they did not hit Locke's joints, could not cut off any of the bones that made up Locke's body with one blow.

Because Locke's body has been shaped and transformed by bone alchemy, the slender and fragile bones on his body have been thickened and strengthened by bone essence, even if it is a fourth-level attack, it may not be able to break Locke's body bones with one blow.

Moreover, Locke's speed and dexterity are far superior to these third-level undead creatures, although he can't dodge the siege of nearly ten existences of the same level, but it is still easy to move his body slightly and dodge the attacks that fall towards his joints. After all, these low-level undead creatures don't have the same intelligence as Locke, and they know how to attack the joints on Locke's skeleton's body.

The siege of nearly ten undead creatures did not reduce the speed at which Locke slashed the third-level undead creatures.

Although it was a bit troublesome, Locke didn't need to go out of his way to the location of other third-level undead creatures, and he was still able to devour the soul fire of several third-level undead creatures in one minute.

As several third-level undead creatures on the side of the bone dragon lord near Locke were besieged and killed, more and more third-level undead creatures sensed Locke's existence and rushed towards Locke's location.

As a result, even if Locke continued to kill the third-level undead creatures around him, the number of undead creatures besieging him around him not only did not decrease, but continued to increase.

Nearly ten minutes have passed, and Locke has devoured dozens of third-level undead creatures soul fire, and the number of third-level undead creatures gathered around Locke has also increased to dozens, so it can be said that Locke has been besieged at this time.

In the face of the siege of more than a dozen third-level undead creatures, even a fourth-level skeleton warrior will be at an absolute disadvantage, and it is very likely that they will be defeated and fall.

However, Locke's physical strength itself is not weaker than that of a fourth-level skeleton warrior, and after the shaping and transformation, the bone defense is stronger than that of a fourth-level skeleton warrior, plus Locke is also a third-level mage skeleton, and has lord-level wisdom, so under such conditions, Locke naturally occupies an absolute advantage.

At the time of the battle, Locke was always intact, at most there were some cracks in the thick bones on his body, which did not damage Locke's own combat power at all.
