The Steady Wizard: From Heart-Switch Rat to Dimensional Demon

The next morning, a ray of golden sunlight passed through the window with simple window grilles and fell on Isaac's smiling face, which looked particularly bright.

Looking at the demonized rat that has grown twice as big on the operating table, its bulging muscles and sharp claws prove that it has been reborn!

This is the result of Isaac's all-nighter - a quad-core driven demonized rat!

Quad-core, that is, four hearts!

It sounds nonsense, but after an extremely detailed understanding of the body structure of the demonized rat through innate witchcraft, and supplemented by magical spells, Isaac was finally able to figure it out.

Four hearts, four times the magic!

Of course, this also means four times the blood supply...

Even if the quad-core demonized rat is blessed with a magic spell, it can only last for a maximum of three hours. If it exceeds half an hour, the body will begin to collapse and its strength will weaken. After an hour, it will be completely unable to move. If there is no magic blessing, then This time will be shorter!

The best combat effectiveness is almost twenty minutes.

But for Isaac, it was enough, because the flesh-to-flesh conversion lasted only one hour, and more magic power was needed to keep him alive in the future.

The most ideal state must be maintained for one hour, but Isaac can only go so far with his current knowledge base.

But that's enough. In a real battle, with the power of the demonized rat, it would be difficult to survive for more than five minutes, unless you were extremely lucky and avoided all damage.

"Tear~"

The ferocious claws came out from the back of the neck, and the back of the hand rubbed Isaac's cheek. Two sharp fingers gently picked up the unconscious quad-core heart-changing rat, gently threw it up, and then fell into the palm of his hand. In the big jagged mouth!

"Crack~Crack~"

Listening to the chewing sound of the devil's claws, Isaac's face turned pale, and then he breathed a long sigh of relief.

Familiar pets are really the best invention in the history of wizards!

However, Isaac was not affected for too long. After all, he had already swallowed a lot. His attention was quickly diverted by the flow of information coming from the claws. This was the latest body structure of the quad-core heart-changing rat.

Isaac narrowed his eyes slightly, and it was exactly as he expected. Although there is still some room for development, the effect will not be obvious. He needs to acquire more knowledge. For now...

It's time to research the blood essence potion.

The blood essence potion is a potion that strengthens the blood. It has a certain relationship with heart transplant surgery and can be regarded as its superior substitute.

After all, the original purpose of heart transplant surgery was to allow humans to possess the power of monsters. The correct way to use this witchcraft is to use it on humans.

After a normal human being is transplanted with a first-level demonized heart, his power will be greatly strengthened in a short period of time, and he will quickly rise to the level of a quasi-knight!

Each person can replace the heart three times in total. If the demonized heart replaced each time is upgraded by one level, then in the end, an ordinary person can become a strong man comparable to the Great Knight!

As long as the surgery is successful, everyone can!

Well, the premise is that the operation must be successful, and the success rate of heart transplant surgery is...

Anyway, there is still a possibility of failure for Isaac, who is pregnant, which shows how difficult this operation is.

The effect of the blood essence potion is the same as that of a heart transplant surgery. It gives the power of human monsters. The difference is that the blood essence potion gives purer blood. Although the effect is not as fast as a heart transplant, it is safer.

And it does not affect the potential, and it may even increase if you drink too much.

After generations of research and development, today's bloodline essence potion can even have an effect on the bloodline of monsters, and many wizards use it to cultivate magic pets.

Although for most wizards, a magic pet is just a partner that makes it easier for them to learn and cast spells, but if it can make the magic pet stronger, that would naturally be great.

However, because of this, the blood essence potion is not very valuable...

It doesn't matter, since he doesn't make money with this, as long as it works.

He is now hungry for all magical knowledge!

"Dong dong~"

"Master Isaac."

But just when Isaac was about to sit down and study the magic spells needed to brew the potion, Butler Smith knocked on the door, which made Isaac frown slightly.

Because he had already told him when he went out to eat before that he should not disturb him unless there was something important.

but……

Although he is said to be a lord, he is actually a manor owner. He only has a few pieces of farmland and manages a village of two to three hundred people. He can't even collect taxes, but he doesn't need to pay taxes. There are many things. Solomon is in charge.

"Come in."

"Master Isaac." After Smith came in, he bowed respectfully to Isaac. When he glanced at the blood stains on the operating table, he frowned slightly and sighed inwardly.

It still turned out like this...

In fact, with the power of the Solomon family, although wizard inheritance is difficult to obtain, it is not impossible. After all, he is a viscount, and his family also has a stable arcanist inheritance.

The reason why I didn't find it for Isaac was because I was worried that he would go astray. After all, the reputation of legendary wizards is very bad, and many witchcraft are extremely primitive and evil. It is very dangerous to delve into these things.

But no one expected that Master Isaac could become a legendary wizard with just a few messy books...

‘Hey~’

Thinking of this, Smith sighed heavily in his heart again, but there was nothing he could do. After all, he was just a housekeeper.

"What happened?" Isaac tapped the scroll lightly and asked indifferently.

"Master Isaac, the guards found goblins outside the castle today." Smith stood up and said with a frown.

Hearing this, Isaac also frowned.

Goblin, a classic and difficult magical creature, with green skin, ferocious face, and a height of about one meter. Although it is a magical creature, its strength is extremely poor. An adult, as long as he overcomes the fear in his heart, can beat a few to death with a stick.

But why do you say it is difficult?

Because the goblins in this world are the product of a legendary wizard, who gave them very terrible fertility. A pair of goblins can lay dozens of goblin eggs!

And the growth cycle is very short. It only takes a few days from hatching to full growth!

And according to legend, this thing has been implanted into the world's laws by the wizard. No matter how you clear and prevent it, every year when the goblins are breeding, goblins will come out from inexplicable places, burning, killing, looting, and doing all kinds of evil.

If it is not stopped in time, its number will increase rapidly in a short period of time!

So once the traces of goblins are found anywhere, they must be cleared up as soon as possible.

"Have you reported the territory?"

"It has been reported, but the guards alone may not be able to deal with them. Do you want to hire a goblin killer?"

"Please, safety is more important." Isaac sighed, and he didn't know if the money could be reimbursed.

Guards are also called militia. They are usually good at public security, and they are not very useful on the battlefield, even if they are facing weak goblins. Goblin killers are extraordinary people who have been given special powers by a legendary wizard. They are good at fighting goblins and can gain power from killing goblins.

Many wild knights survived the most difficult times by killing goblins before they learned the breathing technique.

When Isaac saw this document, he suspected that these two legendary wizards might be the same!

From left hand to right hand, win-win!
