Li Shi naturally thought of taking himself into the Portable Space!
In that case, it would be like having an absolute personal safety house. Whenever he encountered any danger, he could just hide in the space with a thought, wait for the danger to pass, and come out again.
Moreover, in some special circumstances, this method could even turn danger into safety!
For example, when falling from a great height, if his falling speed became too fast to bear, he could enter the space with a thought, then come out again, and the velocity on his body would be reset to zero. In that way, even if he fell from ten thousand meters high without any equipment, he wouldn't have to fear being crushed to death!
Thus, he could frivolously play with those high-altitude activities, and sit in airplanes and hot air balloons with ease.
"However, before taking my physical body into the space, I need to do a live experiment first."
