After refining the stele thoroughly, coupled with the fact that there was no news of the Bone Dragon Lord for several years, Locke was also in a good mood.

In the more than 100 years since he traveled to the undead plane, Locke can be said to have put all his energy on refining the stele, and at this time, completely refining the stele, Locke is equivalent to letting go of a little shackle.

The dwarf cave that had been inhabited for hundreds of years was completely abandoned by Locke.

Locke believed that he would never return to the dwarf cavern again.

Walking in the undead plane, Locke also secretly set several goals for himself.

The current primary goal is naturally to devour more soul fires suitable for undead creatures and increase their strength level. This is also the most reliable goal at present, walking in the undead plane, as long as the strength is enough, there is no need to worry about not being able to touch the undead creatures of the same level.

The second is that after his strength has increased to a certain level, he is trying to get rid of the shackles of the servant contract, and Locke does not want to exist as a servant of the bone dragon lord forever.

Of course, through the information obtained from the rules of the plane when signing the servant contract, Locke also knew the way to get rid of the slave bondage. In addition to the way for the owner of the contract to passively unravel the servant contract, as long as Locke is strong enough, he can also choose to actively break the contract and gain freedom.

However, all of this is based on strength, and Locke can feel that once he reneges on the servant contract at this time, he will immediately be eaten up by the rules of the contract and fall. Therefore, Locke naturally did not dare to hope to get rid of the shackles of the contract now.

Locke's third goal is naturally to leave the undead plane and enter other planes.

Entering another plane, in addition to having the opportunity to use the Flesh Altar, you can also see the wonderful world realm of the different planes. Rather than being a skeleton creature, Locke clearly wants to be able to enjoy the opportunity to be a normal human.

Moreover, once Locke leaves the undead plane, the servant contract based on the rules of the undead plane is equivalent to temporarily losing binding force on Locke, and Locke is also free in disguise.

This third goal, in Locke's view, is even more difficult to achieve than the second. Locke believed that with his own combat power, it would not take decades for him to be able to advance to the lord-level undead creatures, and when the time came, there would be no doubt that he would be free from the shackles of the contract.

And in the past few decades, whether he can be summoned to other planes depends on whether the pie falling from the sky can hit him, and the hope is naturally not very big.

As he moved forward, Locke also sensed the situation around him from time to time to detect whether there was a suitable target for him.

Judging from Locke's current strength, as long as it is a mid-level undead creature, it is suitable as Locke's target.

Although the number of undead creatures in the undead plane is extremely large, the undead plane is a higher plane, and the area is also extremely large.

In the undead plane, the number of zero-level undead creatures is the largest, and under normal circumstances, it takes almost a dozen zero-level undead creatures to encounter a first-level undead creature. And the probability of encountering a second-level undead creature is also one-tenth of the probability of encountering a first-level undead creature.

And so on, the higher the level of undead creatures, the smaller the proportion they occupy.

Therefore, in a short period of time, Locke had some trouble finding the undead creatures that were suitable for him to kill and devour.

Zero-level undead creatures, at Locke's current speed, can encounter one in as few tens of seconds as few as a few minutes or as many as a few minutes. And the first-level undead creatures, in tens of minutes, Locke can also find one, as for the second-level undead creatures, Locke may not be able to encounter them for several hours of rapid progress.

Not to mention the mid-level undead creatures that are suitable for Locke to slash and devour, the number is even rarer.

Although the number of mid-level undead creatures is large, they are scattered in the vast undead plane, and the density is much smaller.

At least, Locke had been moving forward at a rapid pace for a day, and he hadn't encountered a single undead creature above level four. It was a third-level undead creature, and on the way to it, two were found.

Along the way, some low-level undead creatures occasionally sensed Locke's approach, and they couldn't help but dodge in a hurry. The difference in rank makes the low-level undead creatures instinctively stay away from the higher-level existences.

For these low-level undead creatures, Locke naturally had no interest in the slightest. In an instant, he passed over these low-level undead creatures who were a little uneasy, and ran quickly.

The speed at which Locke hurried was no less than the speed at which a level 5 skeleton warrior ran at full strength.

In the blink of an eye, days passed. Over the course of several days, Locke had traversed a considerable distance, almost equivalent to the distance of the entire Bone Dragon's territory.

In the past few days, Locke's luck has not been ideal, and not a single mid-level undead creature has been encountered.

In a flash, dozens of days have passed. For dozens of days, Locke kept moving in one direction.

Fortunately, in these dozens of days, Locke was not without gains, but also encountered two mid-level undead creatures. These two middle-level undead creatures, naturally, Belok slashed and devoured them at will.

It's just that the two mid-level undead creatures that Locke finally encountered were only fourth-level undead creatures, devouring the soul fire of two fourth-level undead creatures, although Locke's soul fire has improved, but it is still far from being promoted to a fifth-level undead creature.

In a short period of time, the opportunity to encounter a large number of mid-level undead creatures is obviously not so easy to be encountered by Locke. At this time, Locke was also secretly glad that he had encountered the great battle that broke out between the previous two lord-level existences, otherwise it would take a lot of effort to advance to the fourth-level undead creatures.

"It seems that we are far away from the territory of the bone dragon at this time. Dozens of days later, Locke sensed that he encountered more and more undead creatures every day, and he couldn't help but think secretly.

Unknowingly, Locke found that the number of low-level undead creatures he encountered every day was more and more outrageous.

Moreover, these low-level undead creatures that Locke encountered were basically zero-level and first-level undead creatures, second- and third-level undead creatures were extremely rare, and as for the fourth-level and above undead creatures, Locke did not find any of them.

"What's going on. Locke wondered in his heart.

In terms of the number of low-level undead creatures that Locke encountered, the ratio of different levels of undead creatures was obviously abnormal.

A day passed, and Locke had encountered tens of thousands of low-level undead creatures, and he should have encountered a few undead creatures above the intermediate level. And the fact is that Locke, an undead creature above level four, has not encountered it.

For such an exception, Locke naturally felt a little puzzled.

What Locke didn't know was that he had inadvertently come to the Sea of Skulls, and it was a Sea of Skulls that had just arrived. The Sea of Skulls, as the name suggests, is the cradle of a large number of undead creatures born in the world of the undead, among which there are various types of undead creatures, but most of them are skeleton creatures, so it is called the Sea of Skulls.

Every Skull Sea is located, because there will be a steady stream of low-level undead creatures born in it, and there may even be a very small number of high-level undead creatures, so near the Skull Sea, a thriving area where many powerful undead creatures are entrenched will gradually form.

In the undead plane, although there are many Skull Seas, they are scattered in the huge undead planes, but they are extremely rare, and it is possible for a Skull Sea to appear in an extremely large area.

Undead creatures in most regions are born through small skull pits.

The vicinity of the territory of the bone dragon Gregory originally belonged to a relatively backward region in the undead plane, and the number of lord-level existences was extremely rare.

However, at this time, due to the appearance of the Sea of Skulls, a sufficient number of zero-level undead creatures will be born from the Sea of Skulls. These weak undead creatures, through continuous fighting, will evolve more and more high-level undead creatures.

You must know that more than ninety-nine percent of the powerful undead creatures in the Undead World Realm have evolved step by step from zero-level undead creatures, and the existence of powerful undead creatures as soon as they are born is extremely rare.

Although Locke was a little strange about why such a number of low-level undead creatures appeared in this area, he did not expect that a new sea of skeletons had descended nearby.

PS: In the new article, Locke will get rid of the contract shackles between him and the Bone Dragon Lord, and how to get rid of it will surprise you.
