Travel Through Time and Become a Eunuch, and Sign in to the Indestructible Power of King Kong at the Beginning

I traveled through time but became a eunuch. What should I do? Wait online. Urgent! Fortunately, Su Ming has obtained the sign-in system. As long as the physical martial arts reaches the third level, he can obtain the magical power of "rebirth of severed limbs" and get back the symbol of man! "Then what are you waiting for? System, sign in for me!" Congratulations to the host for obtaining the physical martial arts technique Vajra Indestructible Kung Fu. Ever since he obtained the Vajra Indestructible Skill, Su Ming has lived a peaceful life of signing in and practicing every day, occasionally killing one or two thieves who wanted to come in and steal things, local leaders who wanted to take advantage of others, the Demon Sect leader who wanted to hold him hostage, and wanted criminals on the Red List who wanted to torture the skills... "Although those enemies were killed by me, this world is still too dangerous. Brother Xun is right. If you don't get stronger in silence, you will perish in silence, so..." "System, continue to sign in!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
