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

"Ugh!!!"

The next day, Isaac roared and writhed on the bed, then slowly got up and yawned widely.

"Squeak~"

"Good morning."

Although he didn't know what the mouse was saying, Isaac still subconsciously replied. Just as he was about to walk to his desk as usual, he suddenly slapped his forehead, cast a spell to clean up, and then walked out of the laboratory.

My father is back, so I can't follow my old habit of starting my research as soon as I wake up; I need to have breakfast first.

Furthermore, it must be done in strict accordance with aristocratic etiquette...

Thinking about this, Isaac couldn't help but sigh. Coming home was just not a good thing...

And you can't not go...

Gaia is a high-ranking knight. If he were to capture a rookie who had just become a wizard, it would be a piece of cake.

So rather than waiting for your father to take action, it's better to be sensible and do it yourself.

"Squeak?" The bewildered mouse was picked up by Harmon and placed on Isaac's shoulder.

"Let's go eat."

As always, the mouse remained bewildered and offered no response.

Hamon sighed, seeing his dazed expression. It was all for nothing... a whole night of studying for nothing!

Although I've always been learning from the first page...

……

Amidst the guards' astonished gazes, Isaac arrived in a pumpkin carriage at a small castle behind the fortress. This was Isaac's and his companions' residence, where he also had a room.

In previous years, he would be brought here to live during the autumn and winter seasons, but he had never been allowed to leave the castle before.

Although he has separated from the family and moved out, that room is still reserved for him and has not been removed. After all, he is a top viscount and his family is about to become an earl, so it's not like they don't even have a room.

However, Isaac did not stay in this room this time. It wasn't that he minded anything, but mainly because running back and forth between the castle and the mage tower every day was too troublesome and a waste of his research time.

Upon arriving at the castle, Isaac slowed his pace and timed his arrival perfectly. By the time he reached the restaurant, everyone had just taken their seats, and he was the last one.

Same as before.

Sitting down at the table, Isaac looked at the breakfast in front of him and raised an eyebrow slightly. Compared to his own meager breakfast, the breakfast here was much more lavish—a pile of roast meat and exquisite pastries!

The delicate pastries were for him and his eldest sister, while the roast meat was for his father, eldest brother, and second brother. They were knights with strong digestive abilities, so it was fine for them to eat a little oily food for breakfast. Moreover, they had a very high energy requirement, and unlike wizards, they did not have a high utilization rate of magic, so most of the energy their bodies needed came from food.

Therefore, the biggest expense in raising a knight is not the knight's secret medicine for training, as you don't need that if you're not aiming for improvement. The biggest expense for a knight is food!

Not only is the demand huge, but the quality requirements are also high. Ordinary food simply cannot meet the demand; it must be the specially prepared high-energy monster flesh and blood.

Not taking medicine only results in little or no progress, but not eating enough can lead to a decline in strength at best, and even starvation at worst!

Noble wizards are different. Their physical condition is only average compared to knights, and they can extract nutrients from magic, so they only need to maintain their daily diet, or even not eat at all.

Therefore, Isaac and his older sister's breakfast consisted of only light and delicate pastries.

It's really exquisite, with small animal patterns on it.

The mouse's beady eyes widened as it watched Isaac devour the small cake with its own image on it!

ate!

They actually ate it like that!

Without the slightest hesitation!

"Hiss~~~"

Seeing the shocked and trembling mouse on Isaac's shoulder, Harmon popped out from behind Isaac's head, pointed a finger at the mouse, his palm cracked open, and let out a hoarse laugh.

Isaac smiled slightly, tapped the mouse's head with his finger, and then handed it a piece of cheese with a mouse head pattern on it.

The mouse hugged the cheese, looked at its own picture on it, opened its mouth several times, and finally gritted its teeth, but couldn't resist the tempting taste. It closed its eyes and took a bite!

"Squeak~"

Then it let out a satisfied squeak~

"hiss!"

Seeing this, Hamon became unhappy, floated in front of Isaac, and opened his blood-red maw, which spanned his palm, in displeasure.

Isaac shook his head helplessly, grabbed a plate of roast meat from his second brother, and poured it directly into the pot.

Watching Isaac interact with the claw and the rat, Gaia and his children were completely stunned. Their eyes told them it was terrifying, but in their hearts, they also saw a touch of warmth...

"My third brother is quite different from when you became a wizard, isn't he?"

"Nonsense! I'm an arcane mage! A truth wizard who believes in the truth! Not one of those weirdo wizards from legends!" Cheryl rolled her eyes after receiving a look from Caesar.

Gaia's lips twitched slightly; he was now somewhat worried about Isaac's mental state...

As for the second son, Remington…

He was right next to Isaac, watching Isaac's interaction with the Claw Rat up close. He'd completely lost his senses and was just sitting there, lost in thought...

Normally, Gaia would have scolded Isaac for bringing his pet to the table and grabbing food from others, and might even have given him a small punishment. But because the pet and the gentle smile on Isaac's face were so abstract, Gaia and the others only slowly realized what was going on after Isaac bowed and left the restaurant...

"Father... in the future... open a restaurant for my third brother separately... for their sake..." Caesar looked helplessly at the servants who were terrified. Some of the more timid ones had even rolled their eyes and were only standing there because of their superior professionalism.

Gaia paused for a moment, glanced at the horrified servants, especially those who had lost consciousness, his lips twitched slightly, and he silently nodded, making a decision that went against ancestral teachings…

We have no choice but to go against it!

Didn't you see that even those maids and butlers with special status were quite frightened?

Over time, one might get used to it, but it could also lead to strange psychological changes, just like Isaac's...

"...No wonder the High Princess wanted to live on her own...The legendary wizard...how terrifying!"

"The eldest princess also changed like the third brother... Is that abstract?" Remington's lips twitched slightly as he came to his senses.

"The eldest princess is also a legendary wizard. Naturally, legendary wizards are not very mentally stable, but mad wizards are even more abnormal. Unfortunately, as far as I know, that eldest princess is also a mad wizard, just like our third brother." Cheryl shrugged helplessly.

Upon hearing this, Remington's lips twitched again. How fortunate they were... to be in the same country as this pair of brilliant strategists...

Is it too late to run away now?
