I! Banished Immortal in the Human World

What is it like to awaken the upgrade system after traveling to another world? There is a master who seems to be very strong, but after practicing for so long, he is still a mortal? Lin Ye was a little confused! If this continues, the monsters on the mountain will no longer be satisfied with their upgrades. But this world is too dangerous. There is great terror outside, and only in the mountains can I feel safe. Going down the mountain? It is impossible to go down the mountain in this life! Life on the mountain is so comfortable, protected by a master, and the public speaks so nicely, why should we go down the mountain? Isn't it just cultivation? It's not a big deal for me... Wait, you can actually upgrade the system? ... I'm just a mortal, and you want me to go down the mountain and die! Fireflies, big-headed wasps, strange fishes: this pest is finally dead!
