Toaru Majutsu no Index: New Testament - Volume 14, Chapter 1: Imagine Breaker and World Rejecter — One_Night_Encount.

Seol Woon-hwi, the Blood Heaven’s Righteous Blade, rose to power, becoming second to none under the heavens, reigning just beneath the sky itself.Yet, at the height of absolute power, he finds himself returned to his past—back to his days as the scorned illegitimate child of the Everlasting Snow Palace.

Chu Xuan transmigrated to a fantasy world and became the young master of a powerful family. He was rebuked for misbehaving just because he sneezed during a banquet. As punishment, he was banished from the ancestral mansion and was relocated to a remote residence.

He did not mind the punishment at all. He just needed a spot that could allow him to be a shut-in. With the system that would allow him to grow stronger by being a shut-in, the longer he stayed indoors, the more powerful he became.

After being a shut-in for a day, he was rewarded with the Indestructible Body Technique.

After being a shut-in for a month, he was rewarded with the Immovable Mountain Technique.

After being a shut-in for a year, he was rewarded with the Yuxu Celestial Scripture and 100 years of cultivation.

After being a shut-in for 10 years, he was rewarded with the Chaotic Indestructible Body and the Bell of Chaos.

…

Chu Xuan declared, “No one can make me leave my home. I like being a shut-in!”

Modesty! Honesty! Compassion! Bravery! Justice! Sacrifice! Honor! Faith!He is a lich, yet he upholds the knightly spirit!He is a lich, yet he remains steadfast in his faith of light!“With a formidable enemy at hand, fearless and unobstructed! Daring and loyal, worthy of the Holy Spirit! Loyal and upright, willing to die unyielding! Protecting the weak, never going against heaven's principles!”Standing at the top of the world, no matter how great the storm, nothing can stop him from following the steps of the Holy Spirit! Not even the Holy Spirit!...This is a romantic legendary story of a chatty cat and a lich who dedicates his body and soul to the light!Yes, “romantic,” not deceiving you! That's just how it is!

Le Xia traveled to the Marvel world. He was born ordinary, but after encountering a dilapidated bronze box, his life was destined to be extraordinary.

“Put on the holy clothes and protect the love and justice on the earth!”

The moment he touched the box, these words were imprinted into his soul.

Whether it’s evil spirits in the dark, covets in the starry sky, or “gods” who regard all living beings as playthings, all evils that try to disturb the peace of this land will face the justice of the saints.

When the golden holy clothes reflected the dazzling starlight and the white cloak fluttered without wind, the legend of the Saint Seiya began to spread throughout the Marvel universe.
