When Locke is promoted to a high-level undead creature, he can obtain the inheritance of the undead magic of the undead sacrifice, which is extremely rare among many undead creatures.

Thinking about it in his heart, Locke immediately understood the true purpose of this necromancer organization to collect a large number of corpses in several countries and a large number of cities. It should be to give a necromancer named Mingzun in the organization a chance to gain the opportunity to comprehend the origin of the undead plane, so as to comprehend the law in one fell swoop, break through the current level, and advance to become a powerhouse in the holy realm.

The thought of the number of corpses needed to perform the undead limit once made Locke feel a pang of horror.

Fortunately, these corpses were collected by many high-level mages in the organization and a large number of mid- and low-level necromancers, and they could also be collected. It is important to know that the collection of corpses in the Dao is the responsibility of the senior necromancer, a large number of middle and low-level mages in various city areas to collect the dead corpses, if the number of corpses collected is not enough, it is also necessary to kill or secretly carry out conspiracy, so that a large number of professionals fight each other and fall, so as to collect enough corpses.

After carefully studying the inheritance information of the Sacrifice of the Dead, Locke naturally had a plan for his future path to strength.

Of course, now that Locke has just been promoted to a high-level undead creature, he is still a few levels away from advancing to the Sanctuary level, so there is no need to rush to prepare for the undead sacrifice. Moreover, unlike necromancers, it is not easy for undead creatures to collect enough corpses for sacrifice. As a result, the way in which undead creatures are sacrificed is also different from that of these necromancers.

After reading all the inheritance information, it only took Locke less than an hour.

Feeling the magic stored in his body, Locke immediately planned to leave here and enter the space full of corpses to refine the dead qi to restore the magic in his body and refine his body.

Within minutes, Locke was once again in front of the stone wall of the passage. With a little force, the heavy stone door was pushed open by Locke, and a dodging Locke rushed into the stone door.

To Locke's surprise, in the stone wall space, Locke did not see the necromancer Zhen, only three undead creatures sat in it.

When several undead creatures saw the stone door being pushed, they immediately became vigilant, and only after recognizing that the person who had entered was Locke did they sit up again. These necromancers are all seventh-level lord-level existences, and although they have little potential, their intelligence is not low.

The task of these undead creatures is to guard these corpses, and if other strange beings break into them, a fight is inevitable. When Locke enters here, as long as these corpses are not touched, these undead creatures will not be bothered, and if Locke hits the attention of these corpses, these undead creatures will inevitably stop Locke.

After entering the space, Locke originally planned to immediately refine the death qi and restore the magic power in his body, but suddenly he had an idea and made a new move.

With a movement of his mind, the Locke Sutra took out the things stored in an inconspicuous corner of the magic bag. These things don't take up much volume, but they are not low, and they are all magical materials. It was the thirty copies of the magic materials that Locke had spent thousands of gold coins to refine the alchemy potion of the undead.

Placing the materials in the magic array according to a certain rule, Locke used his spiritual power to attract the magic array, and a large amount of dead qi quickly merged into the magic array, and with the undead dead qi as the source of power, the magic array immediately began to operate spontaneously.

Under the operation of the magic array, the magic materials placed in the magic array began to quickly melt into a liquid state that flowed into the groove in the center of the magic array. The rich dead qi that was integrated into the magic array, through the action of the magic array, was constantly integrated into these magic materials that turned into a liquid state.

Seeing that the magic array was already operating, Locke no longer paid attention to the refining of the alchemy potion of the undead.

As time passes, more and more death qi is integrated into these liquids, and the undead alchemy potion will also be successfully refined, and once consumed, the undead qi integrated into it will be immediately transformed into the magic of the necromancer.

The biggest difficulty in refining the alchemy elixir of the undead is the establishment of the alchemy magic array, and the rest needs to have enough concentration of dead qi and magic materials to be able to refine it.

Immediately, Locke randomly selected a corner and began to refine the rich dead qi in it.

Under the control of Locke's powerful spiritual power, a large amount of death qi surged towards Locke, and the speed at which Locke refined the dead qi of the undead was much faster than the speed at which the magic array absorbed the death qi.

After a large amount of dead energy was integrated into his body, Locke could clearly sense that the magic power in his body was increasing. The speed at which the magic power in Locke's body was restored was dozens or hundreds of times faster than when he was refining death qi in the past. This is not only because Locke's spiritual power is stronger after he is promoted, and he can refine more dead qi, but most importantly, the concentration of dead qi here is extremely high.

However, even if Locke recovers his mana, it will take a while, because after Locke is promoted to the seventh level of undead creatures, the mana that can be stored in his body has also increased a lot.

"I didn't expect that my magic in my body would be completely restored so quickly. Locke sensed that the bones in his body were already full of magic, and Locke thought happily in his heart.

After being promoted to a high-level undead creature, Locke's body bones also continued to slowly strengthen due to the refining of rich magical power. After each promotion of the undead creatures, the soul fire will first transform, and the spiritual power will be greatly increased, and then the body will be able to store more pure and rich death qi, which needs to adapt to the body bones of the undead creatures, so that the bones can be continuously strengthened.

Ordinary mid-level undead creatures are promoted to high-level undead creatures, and it takes about a year to complete the Death Qi Quenching Bone Enhancement. A year is just a time for other undead creatures to sleep and meditate, and for undead creatures, time has no meaning. Time is equally meaningless to Locke. However, because Locke already has a flesh and blood body, incarnated as a human, and the vitality in his body can only last for a year or two, time is a little urgent.

Fortunately, Locke strengthens his body, in addition to using death qi, he can also use bone alchemy to strengthen his bones by refining the bone essence of seventh-level undead creatures and even seventh-level lifeforms of only the Loki plane, shortening the time for bone strengthening.

Previously, Locke obtained two broken bones, and after refining them into bone essence, Locke's body has been strengthened a lot, and now it only takes Locke more than half a year for the bones to be strengthened to the strongest state.

"It seems that it is time to see how strong you really are. Locke's mind turned. Promoted to the high-level undead creatures, although they did not reach the strongest state, Locke's strength improvement was also earth-shattering. Of course, Locke didn't have a bottom line about whether his melee combat power had reached the level of a high-level warrior.

Although he had just been promoted, among the seventh-level professionals, Locke summoned the seventh-level undead creatures with the undead summoning magic, and his strength immediately reached the top level among the seventh-level professionals.

After recovering the magic in his body, Locke secretly left the base of the necromancer organization.

More than half an hour later, Locke appeared in the middle of the wilderness.

As soon as his mind moved, a familiar spell sounded, and Locke began to summon undead creatures.

No sooner had the spell ended, an undead creature appeared in front of Locke. Locke verified his melee combat power, and the summoned creatures were naturally high-level undead creatures.

The heavy sword had already been held by Locke, and as soon as this high-level undead creature appeared, Locke immediately raised his sword and attacked.

The Skeleton Lord responded to the call of the necromancer from the other world, and as soon as he appeared, he found that the necromancer who had summoned him had actually raised his sword to attack him.

The Undead Lord was a little surprised by the people who summoned the contract that attacked him. The Skeleton Lord didn't know what to do, and the necromancer in front of him was also an undead lord like himself.

However, the Skeleton Lord did not retreat, but attacked directly against Locke.

In the different plane, the skeleton lord is not afraid of enemies of the same level, even if it is a higher-level existence, the skeleton lord dares to come forward to fight, after all, even if he is not defeated, he can escape back to the undead plane at any time.

Although there is no fighting energy in his body, and his strength is not as strong as that of a high-level warrior, but with the heavy sword in his hand, Locke did not fall behind in the fight with the Skeleton Lord.

In terms of speed, Locker's Skull Collar is much more flexible, and he has weapons in hand, and he is an undead creature himself, not afraid of the undead life carried by the Skeleton Lord's attack, all kinds of advantages, so that Locke has the upper hand in the battle.
