What the Hell, I've Become an Immortal and Still Have to Be a Security Guard

Hello everyone, my name is Ye Fan, Ye from Ye Zi, Fan from Mortal. In the original world, I was a social beast. I squeezed into the subway every day, ate takeout, and painted cakes for my boss... No, I was painted by my boss. Until one day on the way to work, a truck completed an epic meeting with me - I flew. When I opened my eyes again, I came to Cangxuan Continent. Everyone here cultivates immortality, and everyone is a scroll king. Others used swords to fly, but I climbed mountains on foot; others used magic elixirs, but I chewed tree bark to satisfy my hunger. Five hundred years, a whole five hundred years! I survived the sect competition, escaped the secret realm to kill people and seize treasures, survived the golden age when the geniuses fell, and survived from the first level of Qi training to the great perfection of the Tribulation Stage. Today is the day I ascend. Nine days of thunder struck me for three days and three nights, but I just didn't say a word - mainly because I was afraid that the thunder would pour into me when I opened my mouth. Then, I came up. The immortal energy is fluttering, the golden light is shining, I, Ye Fan, have become an immortal! The guide from the fairy world looked at me, his eyes were moist, and he held my hand: "He's a new guy! Can you stand guard?" Me: "?" "It's like this" The guide wiped the non-existent tears. "There have been too many people ascending recently, and there is a mix of fish and dragons coming up from the lower world. There is a serious shortage of manpower in the fairy world, so your job is to guard the ascension passage and protect the safety of the new ascendants." "Speak humanly." "Security." After five hundred years of hard training and thirty-nine heavenly tribulations, I, Ye Fan, overcame the tribulations and became an immortal, just to stand guard with a certificate in the immortal world...? And what's even more outrageous is that I actually have a performance appraisal. It wasn't until the arrival of the system that I had expectations for my future life.
