Zheng Yao (protagonist Shou) is sane on the outside but crazy on the inside. After all his relatives passed away, he quit his job and went on adventures in dangerous places around the world. He unexpectedly gained immortality. After a long time, in order to relieve the knot in his childhood, he traveled through a black hole and reached a parallel space. Zheng Changle (protagonist Gong) was abducted and adopted when he was young. He has no sense of security inside and relies on Shou. In order to be with Shou, he works hard to make himself stronger.
