My Great-Grandfather Is Underage

I was an entrepreneur. While trying to save my son, I got into a car accident. When I opened my eyes again, decades had passed, and I was in the same class as my great-grandson. I just didn't know it at the time. A lot of things happened as a result. My descendants had become a family, and they were still striving to make their way. As for me, I went through all sorts of ordeals and nearly had my soul scattered. With no other choice, I had to hire bodyguards to protect me.
