Chen Feng found himself with a rich younger sister from the start, all thanks to a stroke of luck, and successfully activated a System.
Now watch as he pins his opponents to the ground and crushes them.
"Ding! Congratulations! Your grateful heart has triggered this System!"
"The System is giving you a Guide to the Martial World. You can use it once a day. Its effect: grant top-master proficiency in a chosen field for one day. When the effect ends, you will gain a certain amount of proficiency yourself! You can also complete missions assigned by the System to upgrade the Guide to the Martial World and unlock even greater rewards."
