He could do nothing.
He watched helplessly as the uncles were killed by the thugs Jiang Feng had summoned, and saw the junior brothers create a commotion, divide the family estate, seize the master's relics, and even violently attack him, adding injury to injury.

The injuries he had painstakingly nurtured worsened, his dantian and meridians ruptured, and he barely escaped with his life. Most despairingly, the two junior brothers took away his Qiankun Bag.
He wasn't distressed about the cultivation treasures inside, but what truly shattered his last psychological defense was the lost relics.
