A magical energy has entered the jade pendant, giving Ma Chao the ability to travel between two time and space. The four-dimensional storage space of the jade pendant's secondary belt allows the protagonists who travel between two time and space to more conveniently transport the materials they need in the two worlds. With the function of the jade pendant compressing time, Ma Chao can travel between two parallel worlds.
In one world, you can develop your power, build an army, establish a navy, fight in all directions, and eventually become king; in one world, you can accumulate wealth, buy islands, build a base, and become rich.
This book is worth recommending to everyone
