Time flies like an arrow, fleeting in an instant.
In the blink of an eye, six months had hurriedly passed.
Inside the secret laboratory of the Danzo's residence, the ninja researchers had already, according to the cloning technology data Danzo provided them, modified and created experimental vessels for cultivating clones and had successfully nurtured clones of Haruno Sakura and her companions, infusing them with Hashirama Cells to maximize experimental efficiency.
This mode of research was far from a normal experimental process, without control groups, without experimental variables, doing whatever came to mind.
But it wasn't the researchers' fault.
After all, they were racing against time, needing to produce results in an extremely short period. They had to run multiple experiments at once and attain a variety of results.
If an experiment went wrong, they would promptly root out the issue and start a new round, adopting an exhaustive method.
