Experimental Materials

Watching Si happily play by herself, Li Ziming was at a loss for words. "This is our only success?"

"Yes." Seeing his reaction, Nemu frowned, which was rare for her. "Did you think this kind of experiment was easy? Having even one success like Si is impressive. Ancient Zoans and Mythical Zoans are incredibly hard to come by, and the ones we get through Devil Fruits are too limited. We can only use them once..."

"Wait. If someone eats a Devil Fruit, can't that person keep using its power?" Li Ziming interrupted.

"Yes, but do you think anyone capable of eating one would willingly become our test subject? We need a large amount of experimental material at a time. We're lucky if they let us extract cells from them once. There's no way they'd let us do it without limit..." Nemu shook her head helplessly.

Li Ziming had to admit she had a point. If someone asked Sengoku for flesh and blood to run an experiment, Sengoku would probably flatten him on the spot. But it also told Li Ziming that Drake's connection to this laboratory ran deep. There was a Tyrannosaurus there, dead but intact.

"Wait, then what's the story with Si?" Li Ziming interrupted Nemu again.

"You should know that Zoans are common, but their nature can give people some of an animal's wild instincts. It's even more pronounced with Mythical Zoans and some Ancient Zoans. Most people can't control those bestial instincts at all. We made Si directly through biotechnology using the Slime Devil Fruit. Since Slimes aren't particularly dangerous, we felt safe doing it. But other species..." Nemu shook her head. "They're far too difficult to control..."

"I see..." Li Ziming understood her reasoning. He still remembered Kaku of CP9. When Kaku had first eaten the
