I've Already Learned It Wrong

"This is really such a pity..."

Although he knew that even if a potion like this could not be consumed, its very existence still held immense research and academic value.

Severus could not help but feel a pang of heartache. That was an entire Re'em horn. Compared to that, even Re'em blood seemed less expensive.

"There's nothing to regret. What value does a single Re'em horn have sitting there on its own? Only by turning it into something that can provide value does it become useful to me."

But even so, a Re'em only had two horns. Even if brewing did not require adding a whole horn at the maximum dosage, the gap compared with a quarter-pint of blood was still far too great.

Manus was already considering making some biological modifications to the Re'em.

At first, he had merely wanted to make the horns bigger, but that might affect the Re'em's daily life, and besides...

Given a Re'em's size, regularly drawing a pint of blood would have almost no impact. When slaughtered for meat, it could yield around forty pints of blood. Of course, that figure might be slightly reduced after impurities were removed.

No matter how large the horns grew, they still seemed like a drop in the bucket compared to the amount of blood.

Rather than that, it would be better to change the hollow horns formed from keratinized epidermis into solid horns formed from ossified dermis—in other words, horns like a deer's, which could shed periodically every year and regrow.

Although that would completely alter the horn's material composition, as a Potions ingredient, its effect was related only to it being "a Re'em horn," not its precise material composition.

"Overall, this batch of Potions was very successful, but..."

Manus looked at Severus and could not help
