"Sigh..."

Looking at the shadow behind me that was like a follower, I let out a long sigh.

It had been seven days since I found Regulus standing beside me that morning.

During these seven days, Regulus had been following me like a tail. I couldn't shake him off no matter how hard I tried.

For the longest time, I tried to chase him away.

I couldn't stand the thought of a man I had killed hanging around me every day.

He just had to follow me.

I felt bad so much that I was even in so much discomfort.

As a result, I made him go to the woods a few miles away.

I hoped he would get lost or eaten by some predator in the woods.

But every time I wake up from my bed, I would see a horrifying face staring at me.

It was so annoying...

That afternoon, I was directing the Knight King to cut down trees in the woods to make the hut stronger.

Once again, Regulus followed me like a tail.

I turned to look at him, and I suddenly remembered what had happened a few days ago.

It followed me all the time, even when I sometimes wanted to solve a physiological issue.

And every time I slept, I would always be woken to the sight of this scary face.

And...

All these things, at this moment, appeared in my mind like a movie.

Gradually, I felt that I could no longer suppress the anger in my heart.

I picked up the weapon beside me and prepared to give this disgusting guy a vicious sword blow.

When Regulus saw that I suddenly had a sword in my hand and was fiercely looking at him, he also started to feel a little uneasy.

He started to back down.

As he retreated, his hands and feet moved as if doodling, as if attempting to make me give up the idea of killing him.

However, it was as if I couldn't see him. I continued to hold my sword and slowly approached him.

In the end, after forcing him into a corner where he couldn't retreat, I raised the sword in my hand.

When he saw the sword in my hand, Regulus seemed to know that his doomsday had arrived. His hands and feet swayed even more violently.

I fiercely swung down the sword in my hand.

"Bong——"

This sword didn't strike Regulus, but it still made a sound upon impact.

It turned out that while Regulus was randomly rocking his limbs, he had suddenly summoned a spell.

A fireball spell!

A very ordinary magic.

A spell that even an apprentice magician could cast.

He communicated with the fire elements in the outside world, then condensed it into a fireball. Finally, he used his own hand gestures and mind to control the direction of the fireball.

In this world, there may not be a hundred thousand people who could use this magic, but there may be more or less 50,000 people who could use this spell.

This wasn't a rare spell.

However, I was still stunned when I saw Regulus cast this magic.

There was nothing strange about the fireball spell.

However, a zombie who could cast a spell was really rare.

It could even be said that there was only one in this world.

The sudden change in Regulus made me give up on the idea of making a move.

It even made me want to study him.

That was because, a long time ago, when I had just become a Necromancer, I had a thought.

If I were to combine the zombie virus on Earth with the Necromancy magic of this world, what kind of sparks would be produced?

Would I become a new undead species, or would it be impossible?

However, this idea had always been buried deep in my heart, and I didn't implement it.

Because I was the only zombie in this world, I couldn't use my own body and life to carry out this experiment.

If the experiment were to fail, wouldn't I just die?

I wouldn't joke about my own life.

So, this plan had been put on indefinite hold.

But as I looked at Regulus in front of me, the idea resurfaced in my mind again.

Although he had now become a zombie, he was first a person from this world he had become a zombie. He wouldn't reject the power of this world too much.

These conditions meant that the experiment in my heart might have a very high success rate. 

As such, because I hadn't thought of a modification plan yet, I started to accept that Regulus would be following me like a tail every day.

Three days later, in the afternoon.

"Hahaha—"

I, who was sitting on the bed and meditating, suddenly opened my eyes and laughed out loud.

I couldn't hide the joy in my eyes.

Because after such a long time since obtaining the Knight King, I had finally broken through my current realm.

I was already an intermediate Necromancer.

When I had just obtained the Knight King, I could already speak like a human. Now that I had broken through as an intermediate necromancer...

Thinking of this, I immediately stood up and prepared to walk around the room.

I wanted to see if my limbs had returned to the level of a normal human.

When I opened my eyes, I was again taken aback by the sight before me.

A mangled face was staring at me with a pair of lifeless eyes.

Looking at Regulus, I felt helpless.

Even though this had happened for more than ten days, I still couldn't get used to it. I would wake up every morning, open my eyes, and then see such a disgusting face.

Looking at such a disgusting face, the joy of breaking through to become an intermediate Necromancer disappeared from my heart.

I sat down again, closed my eyes, and started to read the [ Necromancer, Research Notes ] in my mind.

I wanted to see if there were any modification plans in the notes that I could learn from. I wanted to start the transformation plan for Regulus as soon as possible.

After all, it wasn't a pleasant thing to see such a disgusting face every morning upon waking up.

The [ Necromancer, Research Notes ] and [ Necromancer, Training Notes ] had the same information about Necromancers that Regulus had in his memories. Every level up, one would be able to flip to the next page.

However, compared to [ Training Notes ], [ Research Notes ] was more focused on the research aspect, with records of the various Necromancers' processes and methods of creating undead.

The level of the intermediate Necromancer that I had broken through this time was an important watershed for Necromancers.

This was because some Necromancers could only remain at the intermediate level for the rest of their lives. This time, there was too much information in the notes.

And because the Necromancers' researches were interlinked, nothing could be skipped.

I could only flip through the pages one by one.

When I was about to finish flipping through the contents, I finally found a feasible plan for Regulus' transformation.

The Lich assistant, as Necromancers called them.

It was a high-level undead and a low-level form of a Lich.

Legend has it that every Lich would have many Lich assistants by their side. They would help the Lich get rid of most of the trouble.

They could release some simple spells and awaken more spells as they grew until they evolved into the high-level undead, the Lich!
