Survival: the System Takes Me to Be the Ultimate Adventure King

[No heroine + Ozaki eight events + restricted area adventure + wilderness survival + extreme sports + live broadcast] I have endless wealth and seven god-level sisters, but somehow I traveled to a parallel world and became an orphan. I also suffered from two terminal diseases and was about to die. Just when I was about to kill myself and travel again, the system appeared! From then on, in order to survive, I embarked on a career of extreme adventures. The Ozaki eight events... The forbidden land of life... Fighting alone with a pack of wolves... Survival in the wilderness... Extreme sports... All will be adventures I want to complete! The introduction is short and weak, readers and readers, please come and take a look!
