Twenty times the gravity had little impact on Shi Feng; during his time in the Yunlai Empire, Long Chen had created a Gravity Stone Cave for him. At that time, Shi Feng's Dantian was shattered but his Power of Physical Body was just as it is now, having reached the Martial Master Realm. He had stayed in a fifty-five times gravity room for three sticks of incense's time.
Moreover, his Dantian was still intact and even fused with the Sacred Flame, naturally granting him Martial Arts Power stronger than that of an average martial master.
