Wedding Night! A Regretful Marriage to Her Disabled Rival! - Chapter 76 - : Our Unique Love in the Land of the Free

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.

In the face of Thanos and his crowd of alien warriors, Jerry took out his wand:

“Avada Suomin”, “Shenfeng Wuying”, “Fuchsia”, “All Petrochemical”…

Withdrawing the wand, pressing both hands on the ground, a huge alchemy formation was formed on the ground, and countless gun barrels roared like thunder.

Get up and put your hands together, the Dragon Slayer Profound Magic is activated, “Red Lotus Exploding Thunder Blade!”

…

Traveling through the Marvel universe, Jerry gets a bizarre panel that rewards Little Red Star for doing good deeds.

Consuming Little Red Star can go to other magical worlds to learn magic,

Consuming Little Red Star can also refresh your mind and speed up the efficiency of learning magic.

In order to protect himself and his family, Jerry reluctantly embarked on the path of constantly doing good deeds to earn a little red star, and working hard to study and learn magic.

The protagonist’s three views are upright, not a virgin, no brainless, no system, the panel is only responsible for traversal and refreshing, all magic is acquired by the protagonist through learning, and powerful through research.

Being able to see into people's past has no real appeal for the teenager this story is about, letting him use it only as amusement and to show off when he was drunk.Never watch into someone's past beyond a superficial level.Never try to find out more than you should.NEVER. EVER. LOOK. INTO. THE. FUTURE.But everything changed the moment he was forced to look into the future, was forced to investigate a murder, and was forced to make the acquaintance of the victim's twin brother('s fists).The more time passed, the more it appeared that the primary reason for this murder wasn't a local problem, but a global one.This single, marred corpse was the beginning of a threat that would shake the world.(MC looses a screw when he enters the prison)BL, first-person view; MC is shuo (perhaps even a reversible couple); love interest falls in love first; both MC and ML are straight, mutual bending, Enemies to Lovers

____this story sets in Japan that developed a little different history from yours.

It’s literally a playtime diary of a girl who is called as “Genocider-san”, “Roaming Last Boss”, “A different person plays the game”, “Raid Boss”, “Ruthless”, “Calamity”, and such by the players.
