Arknights

At the summit of the Garden of Grotesqueries, where the rite takes place, a man with a beard reaching the ground plays weiqi with a white-haired elder dressed in black. The board is atop the altar that suppresses Sui, the stone stands where sacred vessels are placed, serving as benches. The two place their stones with ferocious speed, so before long, a victor is decided. It is the younger of the two.
