To Upgrade and Gain Points, Start by Killing Sewer Rats.

Freshman Xu Yuan was looking for a part-time job during the summer vacation, but was unexpectedly taken abroad to work as a coolie by a sap. There is no end to the road, and a stick seemed to turn on a certain switch. Xu Yuan found that everyone had two more progress bars. What? Can you gain experience and upgrade yourself by killing rats, bugs, etc.? ! Since then. A mouse as big as a cat was chased by Xu Yuan and was scurrying around in the sewers! Mutated mosquitoes the size of butterflies filled the sky and were used by Xu Yuan to practice knife skills! The huge sea turtle that was devouring fishermen on the beach was cut open by Xu Yuan with a knife! ... A year later, creatures from another world arrived. Humans around the world have gained an upgrade point system, and Xu Yuan fell into deep thought as he looked at the more than thirty skill talent points he had not used yet.
