Lin Shen hastily retreated to dodge, while Instructor Mu deliberately controlled his power and speed, maintaining punches just like Qing Jia, yet with force and velocity only slightly more than Lin Shen's.
Instructor Mu's fists descended like a hurricane, leaving no time for Lin Shen to think or space to dodge, forcing him to block with his arms solely based on reflex.
The relentless onslaught, like the fury of a raging sea, showed no signs of abating, pushing Lin Shen into a continuous retreat, his arms feeling as though they were about to break under the unceasing barrage.
With no chance to counterattack, and even blocking requiring a herculean effort, he could only retreat to mitigate most of the attacks.
However, retreating did not free him from Instructor Mu's offensive, which swept forward like a torrent, the punches growing increasingly fierce, faster, and stronger.
