I Really Have a Cheat!

After the spiritual energy was revived, the whole world changed. Sun Zi, an originally ordinary high school student, was suddenly thrust into the spotlight because he was accidentally bound to the dog-licking system, accidentally obtained an invincible "experience card", and accidentally killed the "strongest cultivator". According to the normal traditional "process", one should easily conquer a group of licking dogs, gain the admiration of various bosses, and then reach the pinnacle of life. But... Invincibility is temporary, dog-licking is not something you can do, and no one admits it is serious. I really beat that big guy to death. What, you don't believe it? I really have a cheat. … A-level expert: "You brat, what kind of skills are you practicing? You can actually be as good as me." Sun Zi said: "Old guy, it's not my fault. If you want to fight with me, you can practice for hundreds of years. I am a man with cheats." "What melon?" "... Plug-in." "Outside what?" "A plug-in!" "Melon what?" "What the hell, do you know about the plug-in? It's a system plug-in." The A-level expert said thoughtfully: "I didn't expect that there are mysterious techniques in this world that I have never heard of." "..." From then on, Sun Zi embarked on a journey of subduing licking dogs with a less serious style. Of course, this is also a story about mortals killing gods.
