"Humph!"
Seeing his elder brother speaking, Tobirama didn't say much else, only asking, "Orochimaru, what are we supposed to dig up? Surely you didn't bring us here just to dig a hole?"
However, Hashirama said, "It might be a treasure hunt."
"Treasure hunt?" Tobirama's gaze followed Hashirama's line of sight, landing on the mural in the cave, his eyes narrowing, "The legend of the Sage of the Six Paths? The nine tailed beasts were separated from one monster? Yin-Yang orbs?"
"Humph!"
"Such fanciful mythical stories!"
"Orochimaru, you can't possibly believe this, can you?"
Orochimaru did not respond to Tobirama, perhaps already understanding his character—proud on the surface, looking down on everyone, but deeply respectful towards his elder brother, Hashirama.
Thus, Orochimaru simply looked at Hashirama and slowly said, "What does the First Hokage think?"
"I think a treasure hunt sounds quite fun, I can help," Hashirama said.
"Big brother!"
