In fact, Nawaki had been well aware of the success rate of Wood Release cell transplants from the very beginning. After all, his own Wood Release had been obtained through transplantation, and he had even specifically checked the success rate of Wood Release cell transplants through the system back then. (For details, see Chapter 11 of the original.)
Even with a perfect Asura Bloodline like his, combined with his status as Hashirama's grandson, the success rate was only 90%. For ordinary people, the chance of success was a pitiful 0.1%!
The method Nawaki used to save the failed subjects was not some so-called bloodline fusion. Instead, he directly used the system's "Repair" function to remove the Wood Release cells while repairing their bodies. Naturally, that produced no results. To obtain the Wood Release Kekkei Genkai, they would have to undergo the modification again.
With such a low success rate, Nawaki naturally could not spend a huge amount of Wish Power on repeated experiments.
Moreover, the Wish Power System was Nawaki's most fundamental secret. He could not casually expose it, so he deliberately used "secret technique" as an excuse to conceal it.
Yamato was the lucky one among that 0.1%, and that was the fundamental reason Nawaki valued him so highly!
One had to know that the Wood Release Kekkei Genkai was extremely special. Even for someone like Yamato, whose Kekkei Genkai template did not include Yang Release, exchanging it through the system would still cost a full hundred million points of Wish Power! This alone showed that Yamato's potential was anything but ordinary!
That was why Nawaki had gone to such lengths to save all forty-nine other test subjects: to ease Yamato's inner burden.
Looking at Yamato, whose fighting spirit had now returned, Nawaki felt that everything he had done
