Carefully selected by the all-powerful Sariel, Qin Zan, Si Kong Ming, Yan Meng and Bai Ze, have been chosen to accept the title of “Mr. Time”. With no memories of their own, these four very special men are charged with harvesting the love, family, and friendships of A104, the region of the world to which they’ve been assigned. Going about their work, all of them, repeatedly cross paths with Xiang Ling Er, a girl who constantly seems to be in danger. While none of the Mr. Times can remember Xiang Ling Er, they can’t help but shake the feeling that she is somehow connected to them.
Luo Wu Zi helped Li Si Xiu to build the mound of Qin Shi Huang; the first emperor who united China. His disciples continued to build and safeguard the royal tombstone. In between lies the appearance of the Nine Great Tombstones, also known as Great King of the Graves. For thousands of years, the tombs were never robbed. The outsiders regard these guardians of the tombs like the Tomb Sect. After the death of Luo Wu Zi, the position of Grave King is transferred to his eldest disciple, Mu Rong Xiu.
