It truly wasn't anything precious. It involved some technical know-how, but to him, it was nothing special. These machines were only used to make Sacred Blessing Serum, which wasn't some kind of super-soldier serum.
The principle was to use the genetic similarities within the same species to extract the gene sequence with the greatest similarity, then replace the corresponding sequence in the recipient's body. According to Uchiha Brahman's calculations, that sequence was just right to turn the person receiving the blessing into one of his dependents.
This transformation was irreversible. At its core, it wasn't some advanced genetic modification—not an attempt to give the recipient powerful superpowers or add a special organ to their body.
It was a kind of infection, a transformation that began with the genes and spread through the whole being, body and soul alike.
Rather than calling it genetic modification, it would be more accurate to call it gene replacement.
In other words, even if someone captured a recipient and replaced all their genes and flesh, it would be utterly meaningless. Even if they underwent large-scale genetic modification and were changed from a human into a dog at the genetic level, they would still be Uchiha Brahman's dependent. The moment they were transformed, every change had already become irreversible.
What if the individual's soul were extracted and placed into a new body?
That wouldn't work either. The individual's soul had also been blessed. Once it was placed in a new body, it would in turn infect that body's genes. After all, chakra was a mixture of spiritual and physical energy.
Since no advanced, large-scale genetic modification was needed and all that was required was gene replacement, these machines had only one purpose for Uchiha Brahman: extracting the gene chains that could be considered common genes from
