After crossing the world of the Mysterious Lord and becoming Amon's twin brother, Rosen began his journey through various timelines. He summoned Zhou Mingrui to the Third Age, and played online games with him in the Old Age. Rosen arrived in the Fourth Age with the Red Angel, joyfully beating up Adam, creating the madman Tudor, and helping Azik escape his wicked father. In Sefirah Castle, Rosen enthusiastically aided Zhou Mingrui in beating up the Celestial Lord, allowing Mr. Fool to land as an Angel upon his death, thus achieving the true "Return of the Fool" in the Fifth Age. Rosen was also Roselle's magical pen pal and helped Amon enjoy a complete and chaotic childhood. He left a profound mark in every era, rising to the pinnacle of the Old Age through these traces. P.S.: The protagonist is the son of Shab, following a self-created path, with no syndicate.

"Law Lin's Time Travel Diary":

On the first day of the time travel, I met Amon. I used special skills to summon the projection of the ancient sun god and personally gave Amon a big cunt. I hope Amon likes this heavy fatherly love.

On the second day of the time travel, I received an offer from the Aurora Club. I told them that I wanted my looks, brains, and martial arts, and invited them to join the "Fun Club" I created.

On the third day of the time travel, I met Leonard, recognized my relationship with Grandpa Pales, and rejected Leonard's enthusiastic proposal for Grandpa to move. After all, I don't want to be pointed at by the elders when I go to the toilet.

On the fourth day of the journey, I told Klein that I was going to pray to the god named Fool. I watched his pupils tremble and asked him considerately if he needed eye drops.
