"Oh?" Ye Feng was slightly surprised.
According to his understanding, any authority would envy a genetically modified person with such strength.
Professor Dachto gestured for Ye Feng to taste his coffee before explaining, "Because the genetic modification technology for genetic warriors has an invisible limitation from the start, it is very difficult for people over forty years old to be modified into genetic warriors above C-class."
"It's not just genetic warriors. Even a large portion of the genetic modification technology in the medical field cannot be used on people who are too old."
"Because once a person reaches a certain age, the change of cells and the expression of genes in the body will be suppressed. Even if we modify their genes with manpower and technology and use various means to urge the expression, the final effect will be very weak."
Ye Feng heard this and understood a lot.
