Most people rely on upgrading+
Physical strength can only have a greater impact on you in the advanced stage.
You think of 300 now because you want to build your own house, right?
I suggest you don't learn fitness.
Wait until 50J, and your physical strength reaches 300.
Besides, I don't advise you to build your own house.
It's not good to make your own feng shui.
Find a master or buy a house.
If you don't build a house to get married, I suggest you apply for a trumpet.
In service
Give you something to pack.
Not bad ~ ~ ~
