Slay the Gods: I Have a Magic Phone

Lin Feng transmigrates to the world of Slay the Gods and obtains a magical phone. Its functions include time travel, spatial jumps, energy conversion, and an avatar mode. Completing System missions can also upgrade its capabilities. Lin Feng thought his golden finger was already powerful enough, but then his grandfather, who had been missing for thirty years, suddenly returns at the Klein Realm and passes on to him the Great Heavenly Immortal Art, the Sword-Controlling Technique, the ability to turn one sword into three thousand, and the power to split open the Heavenly Gate with a single strike.
