Jackie Chan: Because I Was Afraid of Pain, I Clicked on Defense

My name is Chen Fan, a time traveler with no great ambitions. My lifelong pursuit is just four words that will never hurt! Fortunately, the [Absolutely Safe Immortal System] satisfies me, as long as I get beaten, I can increase my defense! So, I resolutely embarked on the road of no return of full-point defense. Demonic flames spraying me? Um? Just in time to warm up. Dad's magic? "Oops! Why did daddy's magic fail?!" Sorry dad, maybe your magic power was absorbed by me. Jackie Chan: "Chen Fan! Run! It's dangerous!" Me: "Uncle Long, don't worry. Let him make technical adjustments and let him fight. We'll fight again when we're tired." Xiaoyu: "Cool! Brother Chen Fan is our strongest shield! No, it's a rebound wall!" Dad: "Oh! Why can such a good seedling just be a stone?! You can't fight away monsters!" Daolong: "Interesting, is this almost 'rule' defense some kind of lost ancient magical creation? Or is it a loophole in the world itself?" Holy Lord: "Impossible! Why can't my flames melt this mortal?! What on earth is he?!" However, the cold reminder of the system told me: My absolute defense is like a boulder thrown into the lake, causing huge ripples called chaos in this world. The corrective power of the world has been activated, and I, the walking Bug, seem to have become the new eye of the storm. But I'm really just afraid of the pain!
