Was it ever explained why his older self is so much older than the women? In this timeline, there is only a 5-10 years difference at most between MC and the girls, but elder MC appears to be at least 20-30 years older than the grown versions of the girls.
Yes, he was doing a lot of time travels, lived sometimes at sametime 2 or more times, then aged
If radioactive materials are available then nukes will be making a return soon enough.
Yes and not, in Dr stone explained that the humanity used the surface resource, and maybe will can not recuperate the old technology because there isnt surface material and without tech, we cant reach the deep resource
A good story, was very logic why they meet, only a small problem, how they can create resource (food/water) to sustain 8 billions if the farm is a slow process, they was sending by 2 years, but how .... Dr Stone is more logic in this side
P11, Kiyomi ghost ... the MC dont understand xD, she die at 9 years old (chapter 33, p16) but she is 11 years old, but she is in the black hole zone
Ok .. now I understand about the tiger, the phantom was protecting the MC, but I dont understand the first phantom encounter where the MC did a Jump
But why the human phantoms wanted hug the MC?
