355 Things Left behind by the Deceased

Han Sen had only passed the easiest mode of Sprint. By adjusting and adding the metal walls, the difficulty could be further improved. In addition, gravity inside the device could also be increased.

From level I to level X, Han Sen had only passed level I, which was the easiest among them all.

"Sprint is much better than an ordinary gravity trainer. It must be great for me to practice Overload." Since Han Sen discovered this interesting device, he had come to the lab more and more often.

He mainly came to the lab to use Sprint and was not interested in other tests. He always waited for the researchers to leave the lab before he started to use Sprint to train himself.

As Han Sen had expected, Sprint was not only harder than a gravity trainer, it was also more effective and comprehensive when it came to training his entire body.
