After accepting some quest, Lei Feng started to farm crazily, for a few days he finished every quest he could, letting him promote from bronze to silver, to gold, to platinum, to diamond, when finishing slaying a dragon, people jaw where dropping to the ground, "Bro! Are we playing the same game?!?" Most of the people would be struck at silver because the requirement is to figth against a lvl300 mutated monster to promote to gold, so killings a lvl 1500 dragon was pretty ridiculous for now when only a week passed.
We can ask, why would Lei Feng chose to farm his ranking ? Because he want to make friend! To be famous! So he could forgot his thousand years of loneliness, killing monster around his region, by majority of crushing them to death he got the nickname of the Smasher. He could have used a sword, but it will break if it's a random one, and no monster could have made him ressort to his own sword.
Also, he learned the identity of the player, they are from a world called earth, where they technology is pretty similar to his own, except that most of the country are pretty tense in a economic war.
The receptionist name is Alice, she is not a player but an npc from a system, not really, it's more someone that contracted the system to be safe but her own progress will be slow, something like a remuneration of money and level but only until level 500.
Alice liked to discuss with Lei Feng, he was handsome and always hardworking, as a husband, he could be a responsible father, unknown to Lei Feng, Alice already started to think of their future.
The problem is that Lei Feng don't want any relationship, because he is a thousand years old, but also his sight is not here, he want to find the people of his own world, so he choose to level up crazily, until level 2487.
"Mhmmm, where should I go next? People are getting hurt everywhere and already a million more died from the monster wave!"
From the system news, Lei Feng learned a lot. Sometimes, when the monster are to much in a territory, they will migrate and go in the town to slaughter everyone, except npc, everyone will die.
Lei Feng decide then to go more monster hunting, for a years the name of Lei Feng resounded to the world as the most powerful adventurers, killing dragon, world devouring snakes, evil arch angels. Until no more monster of level 1000 was alive.
Getting to level 5000 he got a skill called portal: can teleport randomly or already save space.
