Protagonist gold fingers are given by me!

Qiang chu crossed into a fantasy world where people can become immortal destroy mountain and seas overturn the world!! But he is not the protagonist or villain! instead he bound the Synchronization system and can become protagonist’s Goldfinger make the protagonist stronger he can also be synchronised with the protagonist and can receive everything enchanting his strength. From then on Qiang chu started this road and became Ring Grandpa, system elf, Divine sword, powerful spirit, lord of reincarnation temple etc.......
