Even for Di Tou, who had a literal gold mine at home, the loss of a High-Tier Spirit Stone still hurt him a little emotionally, as his normal expenses were rather low. Not even to mention a Middle-Tier Spirit Stone, he was barely using Low-Tier ones as all of his recent problems had been solved by basic copper and silver coins!
But at the end of the day, it was a small price to pay for his life and more than anything, Di Tou was happy that the High-Tier Spirit Stone was there, as if it was simply a pile of Low-Tier and Middle-Tier Spirit Stones he had tossed out, there was no telling if he would have directly died before waking up.
