MTL - Start with Batman - Chapter 50 I thought so

In a world where 70% of the population possesses powers managed by a LitRPG chip, Kang Ji-Hoon, a timid young man, joins the prestigious Apex Academy to save his sick mother. Ranked last at F with his seemingly useless ability to summon a dagger, he becomes the target of relentless bullying. Pushed to his limit, he unleashes the true power of his weapon, a dark and destructive force. As he transforms into a ruthless anti-hero, a cosmic threat emerges to assimilate humanity. Ji-Hoon then realizes his dark destiny: to save everyone, he must destroy everything.

After the ‘100-Year War’ between the Necromancers and Priests, an all-time genius who’ll shake the power structure was born. “Am I a rare case or something? Do I have talent?” A potential beyond all imagination. He obtained his father’s undead army and entered the great Necromancer school of Kizen that divided the continent. Geniuses are geniuses, even when gathered among the elites. The research community was flipped on its head by the appearance of a new case. Professors wouldn’t leave him be alone, wanting to make him study directly under them. Officials from all over the kingdom and heads of organizations fidgeted over whether to scout him. “Professor! When can I make a Lich?” “Gimme a break. How talented are you? You’re crossing the line, honestly.” A genius among geniuses had appeared.

Kent is an ordinary wizard in the Sky family wizard school, and his wife Thea also works as an elder in the same school. As Thea is moving out to the elder barracks, she kicks Kent out of the house and puts the house for sale.“You are just a piece of waste who couldn’t earn a silver.” Thea’s last words still lingering in Kent’s soul. (It’s not like Kent is a lazy guy who escapes studies. Most of Kent’s meridians were locked down by a curse.)Suddenly on the same day, Kent received a Raven from his maternal aunt. “Are you really my aunt?” Kent questioned with a doubtful gaze. “Yes, Kent… I have sent 5000 gold and Heavenly elixir to remove your meridian curse. Don’t mind asking me for more money. Your mom left a huge fortune for you.”From that moment Kent’s life changed as he brought a new flying pet equal to core disciples, new weapons, Villas, Fancy meals, and whatnot. Soon, his powers sore and he became a Supreme Arch Magus.

It was supposed to be a perfect deal in which both parties got what they needed. However, after the child was born, he tore up the agreement with discontent and told her, “Who said that we’d only have one child? I want twins! Twin brother and sister! You’ll continue giving birth to more children until you bore me a pair of twins!”
