Steadfast Wizard: From Heart-Swapping Rat to Dimensional Demon God

Looking at the battle that was about to end below the city wall, Isaac silently shook his head. Sure enough, in the world of the extraordinary, individual power can surpass that of the group!

Caesar was merely a half-step high-ranking knight, not even a high-ranking knight. Facing over ninety quasi-knights, more than ten knights, and over a hundred monsters that didn't even reach the rank, he wiped them out in the blink of an eye, as easily as cutting melons and vegetables.

One can imagine how powerful he will be once he becomes a high-ranking knight...

Therefore, although the battle was still far from over, he had no intention of watching any longer. He would rather go back and continue his research. Although his research on flesh-and-blood mimicry had hit a bottleneck, fortunately he had many projects on hand and could switch to another one.

However, just as Isaac was about to turn back to the mage tower to continue his research, he was stopped by his older sister Cheryl.

"Let's go back later. Father will be here soon. Let's go greet him first." As she spoke, Cheryl suddenly noticed the demon rat on Isaac's shoulder and couldn't help but show a surprised expression. "Power? You rat have power?"

Upon hearing this, Remington, who was still in disbelief, suddenly turned his head and stared at the mouse on Isaac's shoulder with even greater disbelief, his eyes wide open!

What is that?

power?

Isn't that something only high-ranking knights and high-ranking wizards are qualified to master?

Compared to the shocked Remington and Cheryl, Isaac was much calmer. He put away the little pumpkin he was about to throw, reached out and scratched the nose of the demon rat on his shoulder, and said with a smile, "It is power, but it's not as magical as you think. It was created based on the special characteristics of the divine species and cannot be replicated elsewhere. Moreover, the effect of the power is quite good; it can only summon and control rats."

"..." Cheryl opened her mouth slightly. How could a divine species be so simple?

Whether it's legendary wizards, truth wizards, or even witches who rely on innate abilities, there are quite a few who study the divine race. After all, no matter what, the divine race is indeed a lower form of the gods, even though the difference between the two is very large.

But it still has great research value.

To this day, Cheryl has not heard of anyone successfully cultivating power from a divine being...

How did you do that?

Cheryl was very curious, driven by a wizard's inquisitive nature, and wanted to find out the truth, but her reason made her restrain this impulse, because it was Isaac's secret.

but……

"Can you show it to me?" Cheryl looked at the demon rat on Isaac's shoulder with some curiosity.

Power is what she is currently striving for. Once she successfully condenses her own power, she will be able to smoothly advance to the rank of high wizard, officially embark on her own path, and be crowned with the title of great arcanist!

Although the method by which the Truth Wizard gathers his own power is different from that of the legendary wizards and the divine species, they are all powers after all, so what if we can get some inspiration from them?

"What are you showing?" While everyone was talking, Caesar had already killed all the black orcs and returned to the city wall. He asked curiously as he took off his battle robe, which was stained with the blood of the black orcs.

"My third brother has cultivated his demon rats to possess power!"

"Oh? That's very..." Caesar was about to give Isaac his usual compliment when he suddenly realized what he meant, and his smile froze. "What? Power? This rat?"

"Yes!" Cheryl nodded emphatically.

Then, Caesar's burning gaze fell upon them...

Isaac: "..."

Isaac watched the three approaching slowly, speechless. He sighed and looked at the demon rat on his shoulder. The demon rat also turned its head to look at Isaac with a bewildered expression, then tilted its head.

"Come on, show us!"

"Rip~"

At Isaac's command, a demonic claw emerged from the back of his neck. After wriggling around for a moment, the claw turned towards the demon rat on Isaac's shoulder, revealing a mouth full of serrated teeth.

"Hiss~"

"Squeak?" The demon rat belatedly paused for a moment, then nodded. It raised its two small front paws and gently rubbed them together, and a peculiar wave immediately spread out from it.

"Swoosh swoosh~~"

"Squeak squeak squeak~~~"

"Rat! So many rats!"

"Holy crap! They're coming up the city wall! Have the rats gone mad?"

"Is it a spell cast by a black orc wizard?"

……

Hundreds and thousands of rats swarmed from all directions toward where Isaac was standing, leaving everyone dumbfounded.

"Let's disband."

"Hiss~"

"Squeak? Squeak squeak!"

Then, with another ripple, all the rats were stuck in place for a moment, and then they retreated like a tide. This scene was enough to send chills down one's spine!

"Hiss!!! It really is power?!" Caesar gasped. He was only one step away from becoming a high knight, so he was the one who knew the most about power among them. Therefore, he recognized at a glance that what he had just seen was indeed power!

"You can't control it?" Compared to Caesar, Cheryl may not know as much about powers, but she has a wealth of knowledge and excellent eyesight. She thoughtfully looked away from the demon rat and then asked curiously.

"Well, because it hasn't been a divine species for very long, its intelligence has improved a bit, but only a bit. We still can't communicate with it. Right now, only the Demon Claw can communicate with it," Isaac said with some helplessness.

Although there are some spells that can promote brain development, Isaac dares not use them on it casually. As the only experimental subject at present, this demon rat is quite precious.

Cheryl nodded, then asked, "Have you named it? Although it's a demon rat, it possesses power, so its potential is quite high. It's worth nurturing."

"A name... I haven't thought about it yet, but I really should, emmm." After a moment of contemplation, Isaac's lips curled into a slight smile. "I've got it! Let's call it Ruicheng! My little mouse will definitely like this name!"

"Squeak? Squeak~" Ruicheng tilted his head, not understanding what everyone was talking about, but since they were all laughing, it must be a good thing, so Ruicheng also smiled.

Suddenly, the demonic claw flew in front of Isaac, baring its fangs and hissing, "Hiss!!"

"Do you want a name too?"

"Hiss!" The Demon Claw tapped its paws. It was clearly the one that arrived first, but the mouse got a name first. It was not happy about it!

"Hmm, that makes sense... Let me think... I've got it! From now on, your name will be Hamon, how about that?"

"Hiss!" Harmon tapped his paw heavily, then excitedly twisted his five fingers in the air, looking utterly sinister...

This bizarre scene also silenced Caesar and his two companions, who were full of curiosity...

In the end, it was Caesar who interrupted Isaac's interaction with his magical creatures. The surprise attack by the black orcs was dealt with, and it was time to go and greet his father.
