"All right, we understand. Please begin," Uchiha Madara said.
"Generally speaking, the core of a first-rank spirit herb is white, the core of a second-rank spirit herb is orange, the core of a third-rank spirit herb is yellow, and the core of a fourth-rank spirit herb is green. Uchiha Madara, Silier, take a look. These four are the low-grade spirit herbs I was talking about," Vastiya said.
"Vastiya, did you forget that I have no spiritual energy and can't see the colors of spirit herb cores?" Uchiha Madara said.
"Oh, I'm sorry, my dear Uchiha Madara. It was my mistake—I forgot. Wait a moment. I'll let you see the colors of the spirit herb cores right away," Vastiya said.
With that, Vastiya poured his spiritual energy into the spirit herbs. A miraculous sight appeared: the four unremarkable spirit herbs immediately began to emit different colors.
"Wow, Vastiya, you're incredible! How did you do that?" Silier said.
"Silier, it's not that amazing. I merely infused those spirit herbs with spiritual energy," Vastiya said.
"So that's how it is. Vastiya, I have spiritual energy too. Can I make those spirit herbs emit different colors like you did?" Silier said.
"I'm afraid you can't, because your spiritual energy can't make those spirit herbs emit different colors," Vastiya said.
"Why not? I don't believe it," Silier said.
"Silier, if you don't believe me, you can try it yourself," Vastiya said.
"How do I try?" Silier said.
"Use these same four spirit herbs in my hand. I'll give them to you now. Try pouring your spiritual energy into them and see whether they emit different colors," Vastiya said.
"All right, give them to me. I want to try," Silier said.
Silier took the spirit herbs Vastiya handed over and poured her spiritual energy into them.
