Lin Tianheng, who traveled through other worlds for 150 years, finally awakened the system in his twilight years.
"I have already become a grand master on my own. If I am going to die, come up with a family disciple training system for me. I have worked hard to build this large foundation, and now you want me to lead these little guys to level up? Do you really think of me as a tool?"
"What? You can extend your life by doing tasks! Can you also travel to all the worlds?"
"Ahem, it smells really good, no, I need to train the little ones at home."
"Practice your martial arts well, Ancestor, or else I won't beat you to death, you stupid grandchild!"
This is the story of an old time traveler who takes his son, grandson, great-grandson, great-great-grandson... To practice (pretend) in all the worlds.
