The first adjustment was very successful, even yielding results beyond Fang Zheng's expectations. However, as he anticipated, when power was completely unleashed, individuals would experience differences in transformations due to varying infections by the Intestinal Virus.
Senju Natsuyo, even when unleashing 100% of her power, wouldn't change in appearance. This was because the dolphin gene prioritized optimizing her brain and nervous system, resulting in almost no visible signs, and her Psionic Rank remained stable at Level 9, with the potential to reach Level 10—the standard of a High Tier Sanctuary Warrior. Fang Zheng classified Natsuyo, who wouldn't mutate even when fully unleashing power, as a "Cursed Child" with Mutation Level One.
