It's a Showdown, I'm the One Behind the Scenes

Gu Zihao travels through a parallel world. Activate the universal mall system. But he didn't expect that he could travel back in time to ancient times to revise history again and again... Unknowingly, Gu Zihao became an immortal, so Archaeologist: Why is this different from when I came to do archaeology before? Eastern Historian: Outrageous... He actually discussed the past and the present with Huangdi... Western historian: wtf? Gu actually used to be friends with Jesus... That's right, I showed off my cards and it was all my fault. I was also the one behind the war. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
