During the sacred Rite of Descension in Liyue Harbor, a silver-haired youth named Su Han makes a simple, cheeky wish for countless wives. Instead of ignoring him, the Geo Archon, Rex Lapis, dramatically descends from the clouds to declare Su Han the nation's newest 'National Treasure.' Shocked and bewildered, Su Han finds himself thrust into the spotlight before the Liyue Qixing.

To explain his sudden elevation, he reveals his secret cheat: the Heavens Mission Group. This mysterious system allows instant telepathic communication across the world and offers a shop where members can exchange mission points for terrifying treasures from other dimensions, such as the Flame-Flame Fruit. As Ningguang, Keqing, and Ganyu realize the strategic value of his abilities, Su Han integrates them into his group alongside his existing friends, Zhongli and Hu Tao.

Now possessing power that could shift the balance of Teyvat, Su Han must navigate his new status while preparing for the looming dragon disaster, all while wondering how his life became so unexpectedly chaotic.
