With the help of calculations from the 'Star Chart', Im determined that the 'five stars merged into the sea', and the gravity change process was extended to thirteen years.
That is to say.
It’s the year 1520 of the Haiyuan calendar.
The starfish's gravity will be about ten times as strong as it is now.
And the year 1520 was when Luffy went to sea in the "original timeline".
besides.
The 'Star Chart' calculated that the 'Five Stars Combined with the Sea' will make the starfish's natural energy more abundant.
Many things happened that had never happened before or were relatively rare.
The most important thing is that it will inevitably lead to a significant improvement in the physical fitness of life around the world.
This in turn allows the starfish to withstand a greater gravity environment.
The two almost complement each other and form a virtuous cycle.
Im reminded of a word that is a bit strange in this Japanese comic universe.
