In My Dungeon, You Are Worse Than a Slime

I, Lin Qi, was scolded so badly by my customers that I missed my footing while delivering food and fell down the stairs into a weird space! Bite! Congratulations on binding the [Dungeon System] and becoming the 9527th City Lord! Your mission: build this desolate land into the most powerful dungeon in the world! [Critical vital signs are detected and all initial points are automatically consumed to create a healing slime. The mobile phone is gone, the takeaway is gone, and you are still trapped in the underground city, with only a clingy and coquettish blue jelly slime in your arms? Lin Qi was about to cry but had no tears, so she could only roll up her sleeves and get started! Four years! Finally, the dungeon door opened with a bang, and the white light was dazzling! Just... Is there still the original world outside? People with superpowers are flying all over the sky. Some people wave their hands to create a flame, and some people raise their hands to summon ice picks! What's even more outrageous is that he disappeared for four years and only two months have passed in reality! "Hey! Who are you? Which ruins did you come from?" Me? He's just the strongest dungeon lord!
