[High-level martial arts, superpowers, sword emperor, martial god, action-packed, humorous, invincible]

Two hundred years after the revival of spiritual energy, ferocious beasts ravage the land, and blood flows across the borders. Humanity has built a defensive line of warriors and superhumans behind high walls, but even this cannot stop the increasingly frequent beast tides.

Lin Hao transmigrated sixteen years ago, waiting in vain. On the day of his awakening, he was found to have the worst E-level lightning talent, becoming the laughingstock of the entire school. Even he himself thought he would live a mediocre life. Until the [Invincible System] was activated, his talent was forcibly modified—the SSS-level superpower [Asura Annihilation Divine Lightning] descended upon the world, and the only hidden profession [Sword Lord] awakened simultaneously! White hair, blood-red eyes, sword scabbard opening and closing, nine swords sweeping across the sky. He ventured alone into the ferocious beast forest, slaying silver and gold beasts, and in a desperate situation, he slew a platinum three-headed mastiff, achieving the first chapter of the "Thunder Prison Sword Master".

As the military massively expanded its recruitment to cope with the crisis, and as top talents from all sides gathered in the Hundred Schools League, he started from the once-renowned but now declining Shancheng Martial Arts University, using thunder as his prison and swordsmanship as his domain. On the league field, he crushed all the strong, making all those who underestimated him tremble; outside the fortress, he single-handedly charged into the beast tide, slaying lord-level ferocious beasts amidst thousands of troops.

However, the real threat had only just surfaced—extraterrestrial demons tore through space, their million-strong army pressing in. At this critical moment for humanity, Lin Hao rose into the air, behind him a purgatory woven with annihilating lightning, before him a demon emperor devouring light. "This body is the Thunder Prison, this sword shall sever reincarnation."

Witness how the Thunder Prison Sword Master, in this chaotic era, proves his Dao with thunder and illuminates his sword heart, carving out a path to heaven for humanity!
