This bone was from a powerful unknown demon, so it was of course very precious. Not even the stomach of the Old Dragon could digest it. Its effect would show up after being ground to powder.
Jing Jiu was pleased with this decision, because he thought the bone wouldn't be wasted and he could also repay the service provided by the Lu family over the years in a small way.
The Zhao family and the Jing family were taken care of by Gu Qing, who sent the magic pills to them every year; so Jing Jiu had no need to worry about it.
Having done this, Jing Jiu turned and walked out of the room, on his way looking for the next whetstone.
State Duke Lu was certain that Jing Jiu forgot what he had said at the Fruit Formation Temple. "The Emperor is really under a lot of pressure right now; should you go to the palace to check it out?" He felt hopeless, but still tried his best to obtain Jing Jiu's help for the Emperor.
