It had only been a few days since Locke left the undead plane, and the soul fires of the fifth-level undead creatures that had been devoured had already exceeded ten. With Locke's current speed, he can summon three or four existences of the same level every day, which is much faster than the speed at which he can find the existence of the same level alone on the undead plane to slash and devour.

Moreover, devouring more than ten soul fires of the same level in a row, Locke's own soul fire was also strengthened by two or three times, and his spiritual power was also greatly enhanced compared to when he was in the undead plane.

In the future, if Locke summons the undead of the same level to slash and devour his soul fire again, his spiritual power will basically not be consumed much, because when Locke devours the soul fire, he will be able to restore the spiritual power consumed when Locke releases the undead summon.

With the enhancement of Locke's spiritual power, the enhancement effect of Locke's soul fire every time he devoured the same level of existence was also constantly weakening, and Locke's spiritual power had already reached more than three hundred meters away from the outside of the body, and every time he devoured a soul fire of the same level, the range of Locke's spiritual power emitted outside the body would expand a little.

Days passed, during which Locke spent some time practicing his epera during the day, and at night he sneaked into the nearest burial place outside the city gates, and began to summon undead creatures to come out and devour the fire of his soul. After more than half of the undead mana in his body is consumed, Locke will refine the dead qi into his body to replenish the undead mana consumed in his body.

Of course, Locke didn't practice epee all day. For Locke, practicing epee requires a lot of physical energy, and every day Locke needs to eat Warcraft meat to replenish his physical exertion.

Almost every day, Locke would practice epee for three or four hours. The rest of the time, Locke occasionally plays with his sister Rowling, or meditates for a while.

After devouring the soul fire of the undead creatures, although Locke does not need to rely on meditation to restore the consumption of spiritual power, he needs to use meditation to digest the surging spiritual power and purify his soul fire, making his foundation more solid.

Under such circumstances, Locke was able to devour the soul fire of four undead creatures every day, and in many cases, he even summoned five undead creatures in a row to slash and devour.

And as Locke continues to summon level 5 undead creatures, the success rate of Locke releasing undead summoning magic is also increasing. In just a few days, the chance of Locke succeeding in summoning a level 5 undead creature has reached more than eighty percent. Such a high success rate is enough for Locke to always maintain his mental power in the best state when he releases the undead summoning magic, and there is no need to rely on meditation to recover the consumed mental power.

"It's a pity that my current mental power is not enough, if I can summon a sixth-level undead creature to slash and devour, I believe I would have already advanced to a sixth-level skeleton mage. Locke felt the surging state of the soul fire in his body, and secretly thought to himself.

As early as a few days ago, Locke had already sensed that his soul fire was showing signs of imminent promotion and transformation, and in a few days, Locke had devoured the soul fire of ten fifth-level undead creatures, and Locke's soul fire still had not transformed and advanced.

This is also normal for undead creatures. Although Locke's current state still meets the criteria for promotion, he may not be promoted at any time, but he is stuck at the door. At this step, Locke can devour more soul fire again and forcibly break through the promotion, or with the help of long-term meditation, continue to purify his spiritual power and build a stronger foundation.

Today is the sixth day that Locke has gone out of the city to the place of burial, and just after a while, Luo has already summoned three undead creatures, sensing the surging soul fire in his body, Locke continues to summon it.

This time, Locke had a hunch that he should break through his current level and advance to the sixth level tonight. Although Locke's knowledge is that even if he is promoted to the sixth-level mage skeleton, his strength will not be raised to the level of a high-level professional, but the strength will increase significantly. When the time comes, in the face of a seventh-level existence, he may have the possibility of fighting back.

The fourth, the fifth, and two more undead creatures were summoned by Locke. After devouring the soul fire of two beings of the same level again, the feeling of Locke's soul fire surging even stronger.

Summoning five undead creatures, the undead mana consumption in Locke's body was just over half. With the rapid improvement of Locke's spiritual power, the upper limit of the undead magic stored in Locke's body is also slowly increasing. Compared to a few days ago, if Locke's body is full of mana, he can summon a level 5 undead creature at one time than a few days ago.

When the magic power in Locke's body was consumed a little again, another undead creature was summoned.

As soon as this undead creature appeared, Locke's heavy sword was directly slashed at the skull of the undead creature. The benefits of Locke's daily practice of the epee are revealed, and now when Locke swings the epee again, he can not only hit the target accurately, but also be able to apply ninety percent of his strength to the epee, making the power of the epee three percent stronger than before Locke practiced the sword.

With a single blow, the skull of the undead creature was instantly reduced to pieces, leaving only a flickering soul fire.

Locke's spirit locks the soul fire, and just by sucking it, the soul fire of the undead creature involuntarily merges into Locke's soul fire.

Summoning and slashing devoured more than thirty fifth-level undead creatures, Locke was already familiar with the process of killing fifth-level undead creatures, and he couldn't allow this fifth-level undead creature to react at all.

As soon as the soul fire of the undead creature was integrated into Locke, he felt that his soul fire suddenly increased. The soul fire of this undead creature is much stronger than that of a general level 5 undead creature, and among the level 5 undead creatures summoned by Locke, the strength of the soul fire can be ranked at least in the top three.

It worked.

Locke was overjoyed in his heart, and after devouring six soul fires of the same level in a row, Locke's soul fire finally broke through the original limit and began to advance and transform.

At this moment, Locke could sense that his spiritual power began to skyrocket rapidly. Originally, Locke's spiritual power that could extend more than three hundred meters away broke through four hundred meters in an instant, and then began to skyrocket at a faster speed.

Every time Locke devours the soul fire of the same level, his own spiritual power will increase slightly, but as he devours more and more, Locke's spiritual power will increase less and less. The reason is that although Locke's soul fire meets the requirements in terms of quantity, it is still lacking in quality.

Now that Locke's soul fire has metamorphosed, it has broken through the original limit qualitatively, and its spiritual power will naturally increase dramatically.

Soon, Locke's spiritual power extended to more than five hundred meters, and it was not until it extended nearly six hundred meters that the growth of his spiritual power stopped.

The soul fire transformation is over, and Locke at this time is already a sixth-level necromancer.

After advancing to the sixth level necromancer, Locke could feel that his strength had improved a lot. Although the increase in strength was minimal, in terms of reaction speed, Locke sped up a little again.

Continuously summoned sixth-level undead creatures, and the undead mana in Locke's body was also consumed a lot, and the mana in his body was only less than forty percent of what it was in its heyday. Moreover, after Locke was promoted, the magic power in his body was not replenished because of the increase in strength.

On the contrary, because of the increase in strength, the upper limit of the magic power that can be contained in Locke's body has increased several times, and the undead magic power in Locke's body at this time is even less than one percent of its heyday.

Locke, who had just broken through, was able to sense the hunger and thirst in his body, which appeared because of the lack of magic power.

Immediately, Locke began to refine on the spot, absorbing the dead qi in the surrounding environment. Under the control of Locke's mind, the undead qi in the surrounding environment moved towards his body at a faster speed, integrating into his own body, and constantly recovering the undead magic in his body.

The speed at which mana is restored is not only related to the concentration of undead energy in the surrounding environment, but also to the strength of the necromancer's mental power. Locke's spiritual power has increased greatly, and the speed of refining death qi will naturally increase accordingly.
