As night fell, Locke changed his outfit again, put his whole body in a black robe, and left Damo City alone. Out of the city gate, Locke had already prepared and rushed towards a target, which was the place where Locke had used a few silver coins to find out a few places where a large number of corpses might exist from the low-level civilian children in Chengda Mo City a few days ago.

Ten minutes later, Locke stopped at the nearest mass grave to Damo City. Mass graves, as the name suggests, are precisely the places where buried bodies are disposed of.

In the mass grave, there is a lot of yin qi, and these yin qi are the dead qi released after the death of life, and it is also the undead dead qi that Locke needs to restore his magic power. Locke sensed it a little, and found that the undead in it was a little thicker than in his own altar space.

Sensing this situation, Locke was overjoyed, but Locke did not come this time for the death qi that permeated it, but for the large number of corpses buried in it. For Locke, having the altar space and piling up these corpses in it can make the altar space give birth to a richer amount of dead energy, and it may even be comparable to the concentration of dead energy in the undead plane.

Locke's soul perception radiated, and he wanted to try whether he could sense the existence of the corpse.

However, in Locke's soul perception, there were only a few fragments of bones on the ground around him. There were no intact corpses, not even larger skeletons. Moreover, there is not much dead air in these bare bones, and the dead air in the bone fragments has basically been emitted into the surrounding environment.

Locke's spiritual power cannot penetrate the ground and detect the situation deep underground.

"How so. In Locke's soul perception, many places in this mass grave area have signs of being turned over by others, and the ground is full of pits, and the corpses in them should have been taken away by others.

However, Locke still pulled out a normal weapon from his magic bag and dug through the area, hoping to dig up some corpses from it.

The ground in this mass grave area was extremely loose and easy to excavate, and Locke believed that the people of the city were burying the corpses of corpses, and it was impossible to bury them very deeply.

With Locke's powerful strength comparable to that of a sixth-level warrior, the speed at which he dug up the ground was naturally extremely fast, and after dozens of minutes, Locke dug up a lot of land. However, apart from the excavation of a few scattered bone fragments in the soil, nothing else was found.

Under such circumstances, Locke couldn't help but feel a wave of disappointment.

Immediately, Locke rushed to another place where many corpses might be buried. More than half an hour later, the place where Locke had arrived was still not much different from the previous mass grave landscape, and the soil and stones on the ground had also been renovated.

Although there are still many fragmentary bones in the mass grave, these bones have been stored for a long time, and the dead air in them has basically been released. In fact, when the corpse is buried underground, it can also gather dead qi and slow down the release of dead qi, but if it is long enough, even if it is buried deep underground, the dead qi will slowly run out.

For necromancers, the best corpses are undoubtedly those that have just died and have just begun to decompose. The death aura contained in such corpses is also the strongest. The corpses that have been rotting for too long have too much dead air in them, and the corpses that have not yet decomposed, the vitality contained in them has not yet been transformed into dead gas.

After passing through two places where the corpses were buried, no corpses were found, and Locke was naturally able to guess that the corpses in them might have been taken away by other necromancers first, after all, only necromancers needed a large number of corpses.

The easiest way for me to collect a large number of corpses has been broken, and if I want to collect a large number of corpses at this time, I can only rely on killing.

The few remaining places where corpses might have been found, Locke had no intention of going any further, and in Locke's mind, the situation in the other three places should be similar to this. The other two places are more than half an hour away from where they are. Outside of Da Mo City, around Da Mo City, there are five places where a large number of corpses are buried.

Locke went out of the city on this trip, and although the purpose of collecting corpses was not achieved, he also found that the concentration of death qi in these two burial places was much richer than in his own altar space, and it was not without gain.

This means that after Locke's mana is consumed in his body, he directly absorbs and recovers his undead mana in this burial place, which is much faster than recovering his mana in the altar space.

Previously, with the help of the undead alchemy potion, the undead magic in his body had recovered to ninety percent of his heyday. At this time, he did not immediately start to absorb mana and restore his own consumption, but planned to release the undead summoning magic in this burial place, summoning undead creatures to come and kill the soul-devouring fire, and after the mana was consumed, he began to refine and absorb the surrounding dead qi to restore the undead mana consumed by himself.

After continuously releasing undead summoning magic to summon level 5 undead creatures, Locke's success rate in summoning undead creatures is also increasing. In order to conserve magic and mental power, Locke only summoned one undead creature at a time. You must know that with Locke's spiritual power, it is possible to succeed in summoning three or four undead creatures of the same level at the same time.

However, Locke's summoning of undead creatures is not used to fight enemies, but to slash and devour, and it naturally makes no sense to summon more than two at the same time, with Locke's strength, even if there is mental arithmetic and unintentional, it is difficult to instantly solve two existences of the same level.

In just a few minutes, Locke managed to summon two undead creatures of the same level and successfully devoured their soul fire. After devouring the soul fire of these two undead creatures, the spiritual power consumed by Locke's summoning of the undead creatures also recovered a lot, making Locke's consumption of mental power almost negligible.

However, the magic power in Locke's body was consumed by about thirty percent again, leaving most of the magic power stored in Locke's storage.

Sensing that night had just fallen, and that he had plenty of time to recover his undead magic, Locke summoned an undead creature again to slash and devour.

Three existences of the same level were summoned in a row, and the magic power in Locke's body had just been consumed by half. After more than half of the mana in his body was consumed, Locke did not continue to release the undead summoning.

Locke knows that the environment around Da Mo City is not safe now, and he is single outside, so it is best to have a certain amount of magic in his body, so that he can only be used from time to time. Anyway, for Locke, after the undead magic power in his body recovers more, he will continue to summon undead creatures, and he will not delay the improvement and transformation of his soul fire.

Sensing the bones of the three undead creatures on the ground that were defeated by himself, there was a large amount of dead qi in the corpses, and Locke naturally would not let them go.

With a thought, Locke opened the magic bag and put into it the three corpses that had just been killed by himself on the ground. In the field, Locke didn't arbitrarily use the stone tablet inside him to load items.

After collecting the corpses, Locke began to refine the dead qi of this mass grave on the spot.

Under Locke's strong spiritual power, the surrounding dead qi was also gathered by Locke, and slowly merged into Locke's body. Although the speed at which the death qi merged into Locke's body was not fast, it was continuous, at least in Locke's perception, much faster than when he relied on the altar space to recover his magic.

Although Locke was concentrating on refining the dead qi, he did not lose his sense of the surrounding environment, and once an accident occurred, Locke was able to react immediately.

As time passed, the undead magic in Locke's body continued to recover.

"It was so quick to recover. "When the first rays of light appeared on the Loki plane, Locke stopped sucking in death. At this time, the undead magic in Locke's body had recovered to more than ninety percent of its heyday, which was slightly more than the undead magic consumed by Locke's summoning of three existences of the same level. Its mana recovery speed was nearly ten times faster than Locke's speed in the altar space.

Such a speed at which the undead mana in his body was restored meant that Locke was able to summon three to four level 5 undead creatures every day to devour his soul fire.

Sensing the speed of his soul fire's enhancement, Locke believed that it wouldn't be long before his strength could improve again and advance to the sixth level of undead creatures.
