Gravekeeper of the Old God Paradise

The first thing Chen An did after escaping from the dimensional space was to go to the tomb! That's right, go beyond your own tomb! However, after Chen An came out, he realized that this was a new era and a new god was established. I was just dust from the old era, until my phone rang. "Chen An, I finally contacted you. I have been out of contact for more than half a month. Are you trying to kill us?" "Professor, what year is it now?" "It's 2028, you kid don't want to say you've traveled through time, right?" "Professor, this is the year 533 of the New Calendar." --- Can't the new era ship carry the old era wine? Then destroy the ship! I, Chen An, sail by myself! New God: Offender, you are breaking the rules of the New Era! Chen An: Did you set the rules? Just call it! They all laughed at me as a relic of the old era, but they didn't know that the system of the new era was just a game I made.
