Basically it was all the scientists fault, if he never found the statue in the first place none of any of that would've happened. (That's also how the mc changed the future with the help of the twin buddha)
Buddha attack/murder mankind and there was a future where all humans died, the older twin (mc) experienced a hell experience of fighting the buddha and having everyone die slowly, but has a power(with the use of the band from the younger twin buddha from the beginning) to travel back to five minutes before mass murder. In the end the older buddha twin made him go back four years to stop the scientists from finding the baby buddha statue. I read this in one go, skipped a few chapter and skimmed some (mainly reading for the twin's relationship). Kinda disappointing that no one got to remember everything but the main character, and what's with them both confessing in the end?? Bruh i wanted a bromance...*jk* it was pretty good. 9/10
