The rise of Hidden Palace in the world should be in recent years. The word "should" is used because no one can accurately say when such an organization appeared in the world. As for what this organization does and what its purpose is, no one knows. At that time, Yinjia was coming down from the mountain. A mask with hollow patterns covered his face, and he wore a bamboo hat on his head. The black veil hid him in the haze. A light blue robe, exquisitely made and well-tailored, with a few daisies on the hem and collar vividly outlining the otherwise extremely plain and elegant temperament. It was precisely because of the hardship of the people at the foot of the mountain that Yinjia personally went down the mountain. As for why he had to cover his face so tightly, Yinjia explained it this way when he was still on the mountain, "But Naijia has an ordinary appearance and an unremarkable temperament. Only this method can strengthen the mystery of the master of the Yin Palace."
