Land realized that these things were most likely products spawned by his own [Life Magnet Field].
Eating things spawned by oneself, of course, wouldn't have any effect.
The two little dragons, as his kin, naturally belonged to high-level life forms.
Their mutation manifestations wouldn't be too obvious either.
Whereas humans and these beasts, with their short lives and weak foundational strength, in a world containing gods, demons, giant dragons, angels, giants, Titans, and other advanced life forms,
had no advantage at all and being considered lower-level life forms was understandable.
It's like in past lives, some animals' excrement would be a delicacy to certain insects...
To continue his experiments, Land intentionally started feeding the Dragon Head Mushroom and Dragon Scale Grass to these Dragon People, while letting them rest near the edge of the volcanic crater where he lived.
