Versatile Mage: I Am the Shadow Monarch

[Shadow Monarch][Harem][Semi-Invincible] In a world where magic and demons intertwine, a deceased father, comatose mother, disabled sister, and a shattered him. Cheng Xiaoyu exhausts all his savings to awaken magic ahead of time for his family's livelihood, just to supplement the household income. But during a wilderness mission, he unexpectedly awakens the Solo Leveling system and obtains the Shadow Monarch's inheritance, allowing him to extract shadows from the bodies of the deceased and turn them into his own shadow soldiers. Slay living beings, extract shadows-wherever the shadow reaches, all belong to the monarch. Cheng Xiaoyu is extremely helpless. He clearly just wanted his family to become wealthy at the start, so why did it turn into becoming the ruler of the world? Gazing at the demon empire surging like a tsunami, he merely spat out three words... "Stand up!"
