Grandpa wad literally to chad to die, I wish we could see some interaction between him and the grandson.
Another thing that miss is about the middle easter child taken by the terrorist.
basically French Revolution and Marie Antoinette, to remind: Marie Antoinette was innocent, they make up accusations and execute her. If we go there, the Queen was a good person even her war at monsters was made up.
if this is close to the end and we don't known anything about her mother and father if not that she died (the father nothing at all). The author will put out something about them right at the end to resolve everything...
this world has no where to settle for now there are just isolated groups that only the MCs can reach because they are immortal (the grandpa has just a ordinary old man), plus the grandpa didn't go to the graves for work, but to visit the graves of his son and wife's son.
