"Phew, success. Somehow managed to complete the circle," he said.

Looking at the rat, he saw a gleam in its eyes. It seemed intelligent and looked at him with hostility. But it didn't move. And the past was like a sick chicken on its deathbed. Sitting and sitting, it could fall any moment. Its eyes were unfocused, how did he know? It just sat there, but its eyes kept darting around. He ordered it to look at one point, and it did, but its eyes still occasionally moved, looking around. It was creepy.

And this weirdo was staring at me, I even felt his bloodlust. I ordered it to look at one point. And now he's still looking while I'm creating new undead. At the same time, I began to wonder what was wrong with this rat.

Suddenly, a book appeared, and it said, "Congratulations on subjugating the first soul."

"Well, well, I started to come up with all sorts of things. But how is this possible?" he thought.

The letters in the book began to slowly change, and new words appeared along with them: "You have taken the first step in understanding souls. You have subjugated a soul that tried to revive a corpse. But, like a true necromancer, you have imprisoned it. You have made its body a prison. However, be warned that the circle you used for the enslavement process is not good enough. It can free itself. It cannot attack you because of the gift, but it can interfere with you. Here is a new gift for your success. Please add these two runes to the already created circle."

The letters disappeared from the book, and two runes with descriptions appeared. The first rune controls the soul, and the second one keeps it in check.

When he tried to draw the runes, he realized he had not yet reattached his left hand. Tapping the book twice, he said, "Hey, how do I reattach my hand?" Taking his severed hand, he hit the book three times with his remaining working hand, causing the book to close.

The book opened again, and on the blank pages, it said, "Restoring Limbs for Dummies."

"Any self-respecting necromancer must know human anatomy. And as strange as it may sound, necromancers are often good doctors. By studying thousands of corpses to create various types of undead, a necromancer must know the anatomy of different body types, creating, so to speak, chimeras of all kinds. This circle initially helps to connect the limbs of different creatures, including even the severed limbs of living and rational humans. This rune is useful both for creating chimeras and for healing."

Reading the introduction, he began to read the main part, about the circle and the runes. Strangely enough, this circle was easy to remember, unlike the previous one. And it works very simply and clearly.

You need two circles: one on the body and one on the severed limb where you need to connect them. After placing the limb in the right place, we connect both circles. And they begin to connect the bones and muscles between them. If the limb was already there, and you just want to restore it, for example, the hand, it will take a few seconds. Quick and convenient.

But if I want to create a chimera from a human with six arms, I'll have to work as a surgeon. If I want to speed up the process, I can add a rune that will create nerves and bones. But this process takes a lot of time.

As it turned out, this method is good for healing, especially for restoring limbs if they exist. But for other purposes, it is too slow and laborious.

Drawing runes on the wounds of his hands, shoulders, and body, he noticed that they were no longer completely black, but had some shade of gray. Perhaps this is a change due to him becoming a necromancer with a heart of death.

Thinking about the last thoughts, he threw them into the cold sweat. No longer thinking about it, he continued to draw the circle. This doesn't mean he gave up on it and became gray. But it's not the right moment now. My sixth sense screams that I'm in danger, and in anime, heroes are often attacked in such moments. Yes, even in movies and games too.

"That's it, it's as if my hand was there from birth. Not a single wound, everything healed before my eyes. If this were in my world, how much money could I earn and find more opportunities. Although, fuck dreams, I need to work."

Closing my eyes and focusing on my hearing, I can barely hear the sounds of battle. And birds chirping, and howling? Am I hallucinating?

Better add those two runes to the circle for this rat quickly. Wait, where was the soul in the corpse? Shouldn't it have already flown into space straight to the rat paradise? If she had just died, I could think that it takes some time for the body to die completely. If you don't know, when a person stops breathing and their heart stops, they are not yet dead because the brain is still alive, but not for long, um, for 1 or 2 or 3 minutes. I'm not sure, I don't remember, I think 1 minute he'll still be alive, until oxygen runs out in the blood.

But I'm sure it's more than one... well, let's say 3 for certainty. He died more than three minutes ago, and the soul is still there. And how resilient these rats are!

No, there's something else here. Ahh... It's not time to build conspiracy theories now. I need to work.

With great effort, I drew the symbol and looked at this creature, it was fighting with all its might. But the hostility disappeared, and now it looks at me like a dog at its owner.

There were several dead rats on its back. One of them stood up and attacked the motionless undead rat, which was rolling its eyes. Terrible, I can't get used to it.

"What the...?" - he watched as the revived rat attacked his first toy... Ahem, undead.

"Don't just sit there. Attack the rat that's hurting you," I gave a precise order to avoid accidentally attacking me or the second toy... undead.

Having received the order, the undead rat turned around and bit the first rat it came across. The other rat didn't expect a retaliatory attack, especially not one so strong. In the next moment, the undead tore a chunk of flesh from the rat, taking its left paw. The undead might have been clumsy and slow, but as it turned out, it was stronger than its brethren. Paw didn't stop there, she tore and ate chunks of flesh.

"Stop," he said in a commanding tone. But she didn't stop and continued to eat.

"Stop eating and step three paces away from the corpse," the order was given again and this time it was obeyed. The undead rat stopped and stepped back, as instructed.

"She didn't listen to my command the first time, but obeyed the second time. What's the difference between these two orders? The second one was more detailed than the first. Maybe that was the reason," he said, tapping his left hand that had already been restored. "Do you know why she didn't obey my first command?"

The book opened again, and on the white page was written, "Everything has its price. The circle you use is insignificant on its own. And for coming back to life, you'll have to pay with complete control. That means giving simple and clear commands."

"But at first, when he was created, he was obedient, and now he didn't obey the order. What does that mean?" the book asked, looking at him expectantly.

"Undead is a walking corpse that can come in various types, ranks, and thousands of races and classes. This soulless undead is a walking bag of bones and flesh. The lowest form of undead. In every undead, no matter what rank, type, class, or race it is, it will always strive to improve its status. And as a soulless undead, it wanted to evolve by devouring souls, becoming undead with a soul, like the second undead."

"Understandable and unclear. I can already guess why he disobeyed the order. But ranks, classes, types, and so on - what does it all mean? And why do some rats have a soul while others don't?"

"I suggest not asking questions right now. If you want to survive by creating undead, you need to increase your chances of survival."

"Well, that scumbag changed the subject... Okay, I'll create undead."

Taking the rat corpses in his hands, he began drawing runes, then connecting them. With each passing minute, 2-3 creatures appeared. The best part about it was that he became more experienced and drew circles faster. If at first he created 2 or 3 creatures, now he was making 5-6 per minute.

Taking a tube in his hand, he wanted to draw a rune to bring it to life, and pounced on it. He barely scratched it before he was caught. Watching the rat struggle, an idea came to his mind.

He broke the rat's legs and then threw it right over the first rat creature.

"Eat and become stronger," he vaguely ordered, hoping that the dead rat would find a way to evolve. I don't know how all this works, but I want to find out what will happen.

The rat began greedily eating the newly resurrected rat. At first, it resisted, but it was quickly killed. Meanwhile, to not waste time, I drew runes, sometimes looking at what the rat was doing.

To my surprise, after eating the first rat, it pounced on another one that was still moving very slowly. As a result, it sat next to other dead kin.

This undead ate one after another. And I didn't even know that there were so many rats hiding.

At one moment, he distinctly heard someone trying to create a passage.

"Everyone gather here," he ordered, pointing to where they should gather.

As one, they moved towards the indicated point, all gathering in a heap. At the same time, a rat's head protruded from the heap of corpses. The wolf's head looked at it greedily. It was ready to attack as soon as it saw the mass of rats pushing each other, but this stunned it. He didn't feel them.

"Catch him and bring him here," pointing a finger at the enemy, all the rats turned their heads towards him.

Instantly, they all rushed at him. The wolf's head looked on in surprise as a crowd of rats pounced on him. Wanting to pull his head out, he realized with horror that he was trapped. At the same time, the first rat bit him on the snout and pulled him towards its master.

Then came the second rat, then the third, and so on. They all bit him on the snout: one on the nose, another on the ear, and two even on the eyes. As they dragged him, some of them tore at his flesh. The wolf's head began to become more grotesque with each passing second.

Rats did not expect or stand still in the face of an enemy like a wolf. The wolf struck at the rats with his front paws, but it was very difficult for him because he was in a narrow makeshift tunnel made of rats.

Inserting his tail between his legs, he began to fight, jabbing and hitting with his tail.

But rats did not know fear or pain, they slowly dragged the wolf, obeying their master's command. Once a rat had been jabbed, it stopped for a moment before continuing to pull. Another flew into the wall with a chunk of flesh in its mouth. After eating the flesh, it ran back towards the enemy. It was all in vain to prevent the actions of this pitiful creature.
