Why Is It so Difficult Without the Halo of the Protagonist?

Lin Chen, a veteran bookworm, once traveled through time and fell into the online universe on his bookshelf. I thought that with the script in hand, I could punch Xiao Yan, kick Ye Fan, and seize all the opportunities in the world. But the reality is, do you want to grab the strange fire? Yihuo thinks he has poor qualifications! Want to steal the fairy grass? The grass jelly will run away on its own! Want to cut off the opportunity? Always being forcibly corrected by the will of the world! He watched helplessly as those stupid protagonists jumped off a cliff to gain inheritance, broke through desperate situations, and had confidants all over the world. And he himself is just a "chosen background" who is slow in cultivation, isolated from opportunities, and always running with him. This year's protagonist is so cool, why is it so difficult without a halo! Until one day, he suddenly looked back—— The unknown soldiers he saved became heroes who protected the country; the simple skills he improved ignited the fire of civilization inheritance; the ordinary formations he set up once protected the future Emperor of Heaven from the catastrophe... Those sons of destiny were composing legends, and he, on the back of the legends, was weaving his own epic called "Mortal".
