Chinese martial arts: From human punching bags to martial arts mastery

Waking up, Chen Feng found himself transported to 1930s Shanghai, a poor man in Zhabei, forced into a human punching bag at an underground boxing ring. The Axe Gang ran rampant, a cannibalistic world that only recognized fists and guns. Fortunately, he awakened the destiny of "Heaven rewards diligence, success is inevitable!" While others relied on talent to train in martial arts, he trained by enduring beatings and sheer willpower! Every heavy blow was experience points for "Hard Qigong"! Every drop of sweat increased his proficiency in "Tongbei Quan"! As long as he practiced, he would become stronger! There were no bottlenecks, no limits! From "Hard Qigong" to "Indestructible Vajra," he could withstand a Maxim machine gun with his bare body! From "Tongbei Quan" to "Tiger and Crane Double Form," he could shatter a cruiser's armor with a single punch! "My name is Chen Feng, the 'Feng' of 'sharp'!" "I don't understand any of the rules of the underworld, I only know—your bullets can't penetrate my skin, but one punch from me can blow your head off!"
