Final Iron Castle

The bifurcation of time has caused earth civilization to take different evolutionary paths. Maybe there are ferocious descendants of dinosaurs living there, maybe there is the extremely powerful Qin Dynasty, maybe there is a super-tech battlefield, maybe there is a world of cold weapons. The endless history of evolution makes everything possible. What Gu Zhi has to do is to breathe the equal air brought by the magical rules of the 'Iron Castle', arm himself with various legendary equipment created by countless splendid civilizations, use his fists and wisdom to run wild among various earth civilizations for his family and friends, solve the mystery of the bifurcation of time, resist the invasion of alien creatures like a tide, and pursue the truth of the end of the original world. The final iron castle, the last refuge of mankind.
