After being strengthened by shaping, although Locke's height has not changed, compared with ordinary skeleton warriors, there are only a few more rows of bone spurs and the bones that make up the body are thicker, and there are no other changes.

After testing his general strength, Locke set out on his way home again.

Although Locke is not a skeleton creature that is not good at speed, but with the speed of his intermediate undead creatures, the average speed is not slower than the speed of the 100-meter sprint champion on the earth. After all, this is a fantasy world with magic weapons, and the incredible things on the earth are just ordinary here.

Moreover, undead creatures do not have the concept of physical exhaustion, and the only thing that is consumed by a long and fast journey is only the consumption of mental power.

As time passed, Locke got closer to where his cave was, and his connection to the mysterious stele became clearer.

Within a few days, the familiar entrance to the cave appeared in front of Locke.

Locke stooped and quickly crawled through the small hole.

Once inside, Locke still had to sit cross-legged, and the dwarf cavern was not large enough to accommodate Locke who was standing.

It was only a dozen days after leaving this cave, and Locke also experienced a life-and-death crisis, and his strength increased greatly.

Stroking the familiar stele, Locke immediately threw himself into refining the stele.

To refine the stone stele, you only need your soul fire to constantly consume spiritual power and constantly refine the stone stele.

Of course, because it requires constant consumption of mental power, Locke also needs to constantly recover mental power.

As a mage-type being, the best way to regain your mental power is naturally to meditate. Instead of the existence of a mage, the recovered spirit generally only needs to rest and sleep for a while.

After the soul fire was raised to the fourth level, Locke's spiritual power increased greatly, and it took a few days for the consumption of spiritual power to reach below the warning line, and he needed meditation to recover.

More than ten days ago, Locke refined the stone tablet, and he needed to meditate almost once a day to recover the consumed spiritual power. But now, he was able to persist in refining for several days, and the speed of refining the stone monument was naturally accelerated.

In constant meditation, Locke devoured a large amount of soul fire, and the hidden danger of skyrocketing strength quickly calmed down.

The fire of the soul was also tempered into a more integrated body, like a pale flame.

As time passed, Locke's refining of the stele became more and more profound.

On the way to refining the stone tablet, in addition to constantly meditating and refining his spiritual power, Locke also studied undead magic from time to time.

Bone spear shooting, Locke has fully mastered.

During this time, the necromancy that Locke studied was defensive necromancy.

The Bone Shield, which consumes the undead mana stored in the body, can summon a bone shield that can appear from any direction around the body to block attacks from all directions.

Of course, the Bone Shield is an undead type of defensive magic, regardless of rank. Several levels of necromancers, when they are cast, belong to several levels of necromancer defense magic.

Locke is a fourth-level mage skeleton, and the white bone shield cast is a fourth-level undead defense magic, which can withstand fourth-level attacks.

However, if the attack strength exceeds level four, the white bone shield will not be able to hold it and will be easily defeated. Of course, with the cushion of the Bone Shield, even if the attack exceeds the Bone Shield's capacity, the damage taken is smaller.

Therefore, it can be said that the Bone Shield is the necromancer's favorite defensive necromancer.

Of course, it's not the same as a bone spear shot. Despite the Bone Shield's good defense, it is suitable for almost all levels of undead creatures.

However, the Bone Shield can only be cast on one side at a time, and can only block attacks from one direction.

And bone spear shooting, as the level increases, not only will the power increase, but also the bone spear that can be cast will also increase, and eventually become a high-level undead attack magic, bone rain technique.

Although for Locke at this time, the white bone shield is of little significance, and it can hardly play a defensive role for Locke.

After all, Locke's body bones far exceeded Locke's level, and only the attack of a sixth-level undead creature could hurt Locke at this time, and as for the attack of a fourth- or fifth-level undead creature, Locke could almost ignore it, and he didn't need to cast a white bone shield to defend at all. The sixth-level attack, but the white bone shield cast by Locke could not resist it at all.

Fortunately, it didn't take much effort to study this undead defense magic.

In between refining fossil tablets and restoring his mental power from sleeping meditation, Locke easily mastered the most common and easiest undead defense magic.

In the plane of the undead, there is a lot of undead power that is inclined to death, that is, undead magic. Locke casts undead magic, and he doesn't have to worry about the consumption of his own mana.

It is far easier to restore one's own consumed undead mana than to restore the consumption of mental power.

Locke's mental power is too much and needs to be recovered through meditation. The consumption of his own magic power does not require Locke's special recovery, and the undead magic power that pervades the entire undead plane is spontaneously infused into Locke's body bones to supplement Locke's consumption.

Therefore, the undead creatures of the undead plane generally do not need to accumulate undead mana to advance, and only need to improve their spiritual power to be able to continuously advance. And the improvement of spiritual power, in addition to meditation, is to devour and fuse the soul fire of other undead creatures of the same level to improve.

This is also one of the rules of the undead plane.

The best way for the undead creatures in the Undead World Realm to advance is also to improve by devouring the soul fire of the same level of existence. Although meditation can also improve mental power to a certain extent, it is not suitable as a way for undead creatures to advance.

After all, the soul fire is not a real soul, if it is not constantly devouring other soul fire supplements, it will also continue to burn and consume, making the efficiency of meditation extremely low, and it is almost impossible to improve spiritual power.

Therefore, at the beginning, Locke did not devour the soul fire, meditated for decades, and was still only a zero-level undead creature, until the soul fusion with Zhang Feng after the most retreat, and after meditation, he broke through the bottleneck at the beginning and was promoted to a first-level mage skeleton.

You must know the Dao, in the normal plane that contains infinite vitality. Among them, ordinary human beings, after decades of uninterrupted meditation, can definitely reach the first or second level of spiritual power, and those with slightly better talent can reach the intermediate level.

Because, normal living creatures have a physical body, and the soul can continue to grow through the nourishment of the flesh and blood, and through meditation, it can naturally improve its spiritual power.

Of course, such a creature with a living existence cannot be advanced by measuring and improving its spiritual power. Instead, you still need to work hard to absorb the magic power that suits your physique in order to be able to advance to a stronger mage.

And although the existence of warriors does not require magic power, they also need to constantly cultivate and strengthen the fighting energy in the body.

Therefore, the strength of other dimensional creatures needs to consume a lot of precious resources. In the undead plane, to improve strength, only enough soul fire is needed.

Although Locke knew the undead plane of the Dao and was not the only worldly realm, he also did not know the situation of the other planes of the Dao.

......

While Locke was refining the stone tablet, the Bone Dragon Lord didn't rest.

However, it took dozens of days for the bone dragon Gregory to digest the soul fire of the ghost he had devoured.

During this time of Bone Dragon meditation, the Bone Dragon gradually recovered from the injuries he suffered from the attack of the Zombie Lord.

When all the cervical vertebrae on his body had grown, the bone dragon Gregory left his territory to find trouble with the zombie lord. As for the dozens of contract servants he still had left, Gregory the bone dragon consciously ignored them.

And these contract servants of the bone dragon have also gained freedom in disguise.

Of course, there is also a limit to the freedom of contract servants such as Locke, once the strength of a contract servant increases and breaks through to the lord level, it will also attract the attention of the contract master, and he will be killed and devoured by the soul fire.

Fortunately, it is not easy for a sixth-level undead creature to advance to the lord-level existence, and among the hundreds of sixth-level undead creatures, there may not be one who has advanced to the lord-level. As for Locke, who only has a fourth-level strength, it is naturally impossible to attract the attention of the bone dragon under normal circumstances.

Therefore, in the past few years, Locke has also been refining the stele constantly, without being disturbed in any way because of the servant contract, but it also made Locke temporarily forget the constraints of the contract.

"It's coming. In the past year, when refining the stone stele, Locke has been constantly reminding himself in his heart.

A year ago, only one percent of the mysterious stone tablet had not been refined. And the remaining one percent, Locke has been refining for more than a year, and he has not completely refined the stone tablet and controlled the core of the stone tablet.

And the mysterious stele, the more difficult it is to refine, the more Locke looks forward to this treasure stele.

Moreover, after hundreds of years of continuous refining, Locke found that in the process of refining the stone tablet, his spiritual power was also tempered more tenacious and mellow in the continuous consumption and recovery.

The more tenacious mental power also makes Locke's ability to control his own skeleton and body stronger, which is also the most important reason why Locke's dexterity is stronger than other existences of the same level.

At the lower level, Locke has not yet discovered the benefits of tempering his spiritual power, only knowing that the path of meditation can stabilize the foundation of undead creatures, but after being promoted to an intermediate undead creature, Locke found that his speed has improved significantly compared to a few years ago, whether it is dexterity or running, the speed has increased a lot.

In the past few years, Locke's level has not improved, and the increase in dexterity and speed naturally comes from Locke's meditation.

A few years ago, Locke's speed was not as good as that of a sixth-level undead creature, but after several years of meditation and improvement, Locke's speed has obviously broken through the threshold of a fifth-level undead creature, and is comparable to an ordinary sixth-level skeleton warrior.

Therefore, after a few years, although Locke did not devour other soul fires, his strength has also improved to a certain extent.
