Chapitre 256: Chapter 161: Unexpected Letter (Two-in-One Mega Chapter)_4

Experimental content: Study on the changes in muscle strength and endurance of horses after taking a mutated growth potion.

Test subjects: Two equally strong black and brown horses.

Experimental process: Recorded the differences over seven days between the black horse, whose feed was supplemented with the mutated growth potion, and the brown horse, which was not.

The day before departure.

Rein obtained the experimental conclusions.

Experimental conclusion: After seven days, no prominent mutations were observed in the black horse, but it is estimated that the black horse's muscle strength and endurance have increased by about 20%.

Clearly, the mutated growth potion could not only be used on dogs but could also strengthen animals to a certain extent.

That afternoon, someone Rein knew well but had not expected at all visited his home—Shadia, the Chief Maid from the Habsburg estate.
