Runeterra: I Transmigrated with the Ultimate Spellbook!

Yan Chuan was an otaku sitting in front of his computer. After waking up, he found that he had transmigrated to Runeterra, and even brought along a System called the Ultimate Spellbook!

Basic abilities, ultimate abilities, and the heroes themselves: I'll take them all!

Looking at the turmoil across Runeterra caused by Viego, the Ruined King, Yan Chuan decides to step forward, save countless female heroes from peril, and hold them close before they fall!

Lucian: "What? My wife Senna just got away from Thresh, and now she's run off with some punk!"

Senna: "Yan Chuan is way better than Lucian and his toy pistol."

Ashe: "When is Brother Yan Chuan coming over today? I've had more than enough of that barbarian's five short seconds."

Miss Fortune: "The only man who can become King of the Pirates with me is him."

Sona: "When will the brother who taught me to play the zither come back?"

Under the Spellbook System, all abilities can also be fused and upgraded!

Looking at the countless beauties lying beside him, Yan Chuan thinks to himself: I'm definitely going to save Valoran!
