Dedicated to the tomorrow that can never be reached again. (This book is also called The Journey of Days Gone By in Another World.) The protagonist, Bai Yi, died suddenly while grinding in Days Gone By. By chance, he transmigrated to a parallel world, only to discover that Days Gone By was thriving there. He then became bound to the Days Gone By Assistant System and took it with him to conquer a new server, grind levels, raise his combat power, climb to the T0 tier, and become an unknown creature on the new server. While pursuing greater combat power, he also made time to fish and cook with his live-in companion, take in the beautiful scenery on the Days Gone By map, contribute to their camp, and work with its members to build a beautiful, peaceful retirement retreat. In this life, he would do his best to make up for the regrets he had from missing out on things in Days Gone By in his previous life.
