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

"What are the costs? What are the profits? Is it complicated?" Caesar's eyes lit up as he quickly asked.

"The cost... should be over a hundred gold coins. It includes bloodline essence potions and some other strange things, probably things that Third Brother researched himself. As for the profit... the price will decrease with large-scale production, around thirty gold coins. If we can breed dragon lizard cubs ourselves, the cost will be further reduced. As for whether it's troublesome, you'll have to ask Third Brother."

After saying that, Cheryl turned to look at Isaac.

Isaac looked at his older sister with some emotion. As expected of a big shot who was about to become a high wizard, her eyesight was truly amazing. She could see almost everything with just a glance.

"It's pretty much like what my older sister said. It's not troublesome at all; normal breeding is fine." Isaac shrugged.

Although awakening the dragon blood requires his cheat ability, it only requires a trip during feeding and won't be too troublesome.

Moreover, once his skill level improves further, he can completely integrate the steps to awaken dragon blood into potions, at which point a single potion will suffice.

Caesar did a quick calculation, then nodded excitedly: "Alright! Third brother, go and organize the data, write down all the necessary resources, and we'll take over this project!"

Out of caution, Caesar did not directly state how much money he would receive. After all, he was still only the first in line to the throne, not the real Viscount Solomon, and the specific amount would have to wait for his father to decide.

But we're all family, so it's not like we'll be missing anyone.

Isaac understood this, so he didn't dwell on it. Instead, he lifted the black cloth covering the second carriage, which mainly contained his various experimental subjects.

"Huh? Heart transplant, blood transplant... your arrangement..." Cheryl immediately noticed the four somewhat listless demonic rats and the numerous surgical scars on their bodies. After a moment's thought, she looked at Isaac with some surprise, "You're catalyzing demonic hearts and demonic blood?"

"Yeah, just trying it out." Isaac nodded with a smile, much calmer about this.

Compared to the dragon lizard, the experiment of catalyzing the demon heart and demon blood is child's play. This technology is not actually very technical. The main difficulty lies in the idea and its complexity.

Whether it's a heart transplant or a blood transfusion, surgery is required, and the procedure is very complex and quite dangerous.

This is at least true for other formal wizards in the current era. Limited environment and immature surgical techniques are the biggest risks of surgery. Although these risks can be mitigated with spells, this only increases the complexity of the surgery.

In the end, all they get are demonic hearts and blood, and naturally no wizard would do something so counterproductive.

But Isaac was different; he was poor!

So he's willing to study any method that can make money!

Besides, it's only complicated now. Once he's skilled enough, he can try to optimize it into witchcraft or ritual, making it much more convenient.

This is not Isaac's fantasy; in fact, modern witchcraft and arcane magic originated in this way, simplifying complex concepts and increasing their practicality.

For example, Arcane Missiles in the three basic arcane spells, in its most original version, requires a complex process to cast, including preparing an appropriate amount of arcane energy, a spell to maintain the arcane energy structure, and a spell to lock onto the target. Although it is a combat spell, it cannot be used in combat.

Now, however, Arcane Missiles no longer require chanting spells. They can be released directly by using magic and mental power to activate the spell model in the mind, making them many times more convenient!

He firmly believes that sooner or later, he will be able to simplify this technology!

The demonized rat experiment didn't hold Cheryl's attention for long. Its technical sophistication and value were mediocre, with only the idea being somewhat interesting. But it was something only a poor person would make, and she didn't care about such a small amount of money.

Her gaze was quickly drawn to another demon rat quietly sitting in its cage. After looking at it for a while, she said uncertainly, "Is this a divine species?"

"Yes, I learned it from the witchcraft manuscript my older brother gave me."

Cheryl: "..."

Cheryl was silent for a moment, then turned to Isaac and sighed heavily, "Third brother, it's such a pity you don't have arcane talent!"

She had read that witchcraft manuscript. Although she hadn't read it carefully, she could still tell that its contents were obscure. The alchemy recorded in it was extremely complex, and even she might not be able to learn it.

And now, Isaac, who has only recently become a wizard, has actually mastered the wizarding manuscript and transformed the alchemy within into surgical modifications...

Isaac smiled slightly and did not reply; those were all things of the past.

"What's the value?" Caesar couldn't discern the technical sophistication involved. After being provoked by the dragon lizard, all he wanted to know was whether he could make money, and how much!

"From a purely magical knowledge perspective, it's priceless, but from an economic perspective, it won't make much money. Spreading it across a large area might not even be as profitable as planting Silvermoon Grass," Cheryl shrugged and said casually.

"Isn't there some kind of divine species? Why is it so low-class?" Remington asked, somewhat puzzled. Dragon species are so valuable, how could divine species be inferior?

"This is different. Dragons are treasures from head to toe. A divine species is at most a special kind of monster. Its strength is unpredictable and it is extremely difficult to tame, so its value is not high. The value of a divine species lies in the knowledge it contains, but this one cannot be sold." As she spoke, Cheryl looked at the divine species, the demon rat, again.

"Third brother, why did you think of transforming the demon rat into a god-like species? It's such a waste that it's so weak."

"..." Isaac was somewhat speechless. "I'm not as rich as you, big sister. What right do I have to choose?"

"That makes sense." Cheryl thought about it and nodded in agreement.

She knew just how difficult it was to be a wild wizard.

"Alright, we've looked enough. Let them keep it for now. Come on, let's go eat." Caesar clapped his hands and said.

The other three siblings nodded, handed the things to Smith, and went with Caesar to the fortress canteen.

……

"From now on, you can conduct your experiments here. Just throw the magical waste you produce into the trash can, and the tower spirit will have the puppets clean it up."

After they had eaten and drunk their fill and finished chatting about everyday matters, Cheryl led Isaac to her mage tower and temporarily gave him the vacant third floor to use.

Looking at the much emptier laboratory, Isaac nodded with a sigh. This was quite a leap forward!

"Thank you, big sister."

"Say that." Cheryl smiled and shook her head, then took a spellbook from her sleeve and handed it to Isaac. "Have you finished reading the spellbook I gave you before? If you have, you can learn from this one."

"This is... The Truth Wizard's Combat Manual, Volume 1? Can I have this?" Isaac looked at Cheryl in surprise after glancing at the title.
