It is assumed that Marco gained Devil Fruit abilities when he was a child. After taking the Phoenix Fruit, he came to a strange world. And met a "benefactor" who has a profound memory.
After spending thousands of years with Yun Ze, he returned to the day when he took the Devil Fruit, and those past became blurred. Later, he became the captain of the first team of the Whitebeard Pirates and the first mate of the Four Emperor Whitebeard, and he met his "benefactor" again.
Note: The heroine's atypical time travel involves cultivating immortality.
The heroine is a mermaid and has lived for a long time. After meeting the phoenix Marco, they became friends and made a promise. The heroine was in the navy in the early stage and adopted two children! ! ! ! [There are many private devices! ]
Purpose: I like the character of Marco
