Standing in front of the mass grave, Liu Zhi looked at the corpses that wanted to crawl out of the ground, and suddenly had a feeling in his heart that he knew what the mass grave was for.

As he was letting his thoughts out, several corpses had already crawled out by force.

These corpses were all ordinary skeletons, they were directly dry bone racks, the color of the bones was a little dull yellow, and they looked relatively brittle.

After they climbed out, they did not leave the mass grave, but wandered aimlessly around the area.

Liu Zhi noticed that under their feet, there was always some black yin qi injected into their bodies.

After thinking about it for a moment, Ryuji walked towards the mass grave, and he noticed that in the mass grave, there were some arms with carrion that were trying to climb up.

This should be the zombie or walking corpse as previously suggested.

Before walking to the mass grave, Liu Zhi suddenly popped up a control bar in front of his eyes, this is a control bar for the mass grave, which can only be activated by standing in a certain position in front of the mass grave, and will automatically disappear after leaving.

Here Liu Zhi saw a pinching interface, on which there were already four different necromantic existences.

[Bone Creeper: Only the skeleton on the upper half of the body remains, which is of no use, and can only be used as a sacrifice or a material for repairing other skeletons. 】

[Wandering skeletons: Skeletons without souls, purely supported by yin energy, instinctively wandering in mass graves, only when ordered to complete some work, when there is no order, they will return to their original location to wander. 】

[Walking corpse: A wandering corpse, because the muscles on the body are not completely decomposed, it is less likely to disintegrate than a wandering skeleton, and can be used to do some heavy physical work. 】

[Skeleton Soldiers: Skeletons that slowly produce intelligence, they will kill their own kind to strengthen themselves, and they have a certain combat effectiveness. 】

Looking at the situation of these four types of necromancy, Liu Zhi generally understood the situation here in the mass grave, which is to give skeletons and walking corpses as materials and labor, as for what will be obtained in the end, it depends on each person's own research results.

The wandering skeletons and skeletons in front of them actually looked similar on the surface, except that the skeletons were carrying the bones of other wandering skeletons or bone-crusher creepers in their hands.

Ryuji noticed that many of the skeletons were clutching the spine of a bone creeper as if they were carrying a chain hammer.

Liu Zhi casually summoned a few skeleton soldiers and let them fight with each other, and finally found out a little helplessly that the combat level of these skeleton soldiers was like that, and they didn't care about any defense at all, and directly took the weapons in their hands to smash each other.

And their weapons were also forcibly torn from other skeletons, shattered after two smashes, there was not much advantage, the only good thing was that such weapons were everywhere.

Liu Zhi thought about it for a while, and understood in his heart that the skeleton soldiers recruited here are actually given a basic template, and after being summoned, weapons and equipment still need to be provided by the necromancer.

"That's okay, you can prepare a few obsidian spears and then you can change your outfit, skeleton soldiers are more flexible, whether they are spearthrowers or pikemen, they are all good choices."

Liu Zhi muttered to himself, and was ready to let the mass grave generate a group of skeleton soldiers, and first replenish his undead troops.

But at this moment, he suddenly discovered that there was a small plus sign under the four different necromancers.

Ryuji clicked on it, and found that there was an extra grave-like thing under the pinching interface, and when he focused his attention on it, he would see that there was a writhing skeleton inside.

Ryuji would then find that he seemed to be able to put something on the skeleton.

For example, directly give the skeleton a weapon or equipment, so that he will be armed as soon as he comes out.

Another example is to give the skeleton a certain amount of yin energy, so that he is naturally stronger than other skeletons.

However, this is not the most important thing, the most important thing is that Liu Zhi noticed that as long as he knows how to skill, he can consume a considerable amount of skill points and inject it into the skeleton.

For example, at the beginning, Ryuji consumed 30 points of experience to learn [Sailor Basic Swordsmanship Level 1], as long as he is willing to consume another 30 points of experience, then this skeleton will also master the Level 1 [Sailor Basic Swordsmanship]. 】

This made Ryuji think of a possibility.

He chose a skeleton that hadn't crawled out yet, and spent 60 experience points to upgrade the [Sailor Basic Swordsmanship] and [Sail Control Technique] to level 1.

Then, sure enough, a new prompt popped up.

[Hint: If the skeleton meets the standard of deputy position-sailor, whether it is trained as a skeleton sailor.] 】

"Yes."

Ryuji made his choice.

At his command, a new skeleton crawled out from under the grave, and a new image was fixed in the selection screen.

Ryuji took a closer look at the skeleton and found that he looked too different from the others, the only thing being that the arm frame was significantly thicker, and the bones were mostly rusty.

[Skeleton Sailor: A skeleton transformed from a dead sailor, remember the sailor's basic swordsmanship and sail control skills, which are more suitable for fighting on the water, and each recruitment costs 60 experience points. 】

Looking at this situation, Liu Zhi was somewhat moved, and then he turned his head to look at the other two swordsmanship skills he knew, and then looked at the rest of his experience, and then gritted his teeth and clicked on the selection bar again.

However, this consumption did not get any good results, the two new skeletons are still skeleton soldiers, but one of them has mastered the [Z Word Secret Sword Level 1], and the other has mastered the [Indigo Wind Chasing Sword Skill Level 1], which may be able to exert the effects of these two swordsmanship in battle, but usually they are just skeleton soldiers without a profession.

"Forget it, I thought there was a chance to train new troops."

After sighing, Ryuji began to check the production aspects of the walking corpse again, but compared to the more skeletons, there are not so many corpses that can be used to transform the walking corpse.

Liu Zhi searched for a long time, but only found two experiments, and in the end he only transformed one of them into a walking corpse sailor, which was considered to be a new class, and the other he wanted to turn into a swordsmanship type, but he found that the movement of the walking corpse was too slow, and both swordsmanship were wasted on them, so he had to give up this idea in the end.

However, this also made Ryuji know the use of mass graves, and it seems that in addition to the combat troops, there are many other deputy positions that can also be trained here.

This is also a good thing for Ryuji, at least he doesn't have to worry about his Hades being empty.
