Endless Upgrades: My Beautiful Landlady

"Revenge + Crazy Upgrade + No System + Many Professions + Farming + Sinister + Single Female Protagonist" "Congratulations to the player for awakening the exclusive talent for unlimited upgrades!" That day, the BOSS of Novice Village was silently waiting for his first challenger, until one person appeared. When watching the door slowly open and the first number 8 appearing above the player's head, the BOSS smiled disdainfully in his heart. "Level 8?" "You actually dare to challenge me." The next second, there was another 1 in front of 8. BOSS couldn't help but comfort himself. "It's okay. He's only level 18. He's alone. He may not be my opponent." When the word 1 appeared before the word 2 again, BOSS fell into deep silence as he looked at the level LV10 displayed above his head.
