I'm Learning How to Kill People in the City

After waking up, Lin Mo found that he had traveled to another world. With a warm little home and a "kind" "mother" on her face, Lin Mo strives to play the role of "son" well. It wasn't until "Mother" turned into a terrifying monster in front of his eyes that he realized that the world was full of danger and death. The old man who had died long ago but was inexplicably resurrected, the orphanage that was completely isolated, the town that was wiped off the map, the weird ringtone from the cell phone in the middle of the night... When the world gradually fell, weirdness began to revive, and human beings were struggling in death, Lin Mo, armed with a three-foot green sword, suppressed all the weirdness in the world alone!
