His Dark Desire: Tales of a Yandere - Chapter 28

Lu Yuan was originally just a normal ordinary person, but one day he passed through it and became a day of destruction with a splendid reputation in the DC universe.

Doomsday does not refer to a single monster, but a terrifying legion from the technological civilization of Krypton.

But Doomsday is not a superman. In fact, it is a terrible biochemical weapon invented by the dead body of Kryptonian who got superhuman power and resurrected.

Lu Yuan became one of the doomsdays after just passing through, and entered the core of the sun for 100,000 years.

One day, Lu Yuan woke up, but when he flew back to Earth, he found that this place is no longer the Earth of the DC universe. I don’t know why he seems to have come to Marvel?

“Isn’t this invincible? Without kryptonite, I would be God.”

A series of short stories in the world of Toaru Majutsu no Index organized into chapters featuring Kanzaki Kaori as the protagonist, going around the world and space doing missions for the Church of Necessary Evil, however, there is more than meets the eye as each incident is connected.

One chapter was bundled with each limited edition release of the Toaru Kagaku no Railgun anime DVD and BDs, with all of them together being equivalent to a single normal Toaru Majutsu no Index volume

In this world, Planet Earth had undergone great changes and humanity is faced with extreme danger. Luckily, humans have something called the Heaven Dao software.

It tells a poignant love story. He was the most heroic man in history, and before his death he sang a sad song about a woman; she was the most charming woman in history, and before her death she danced a story about steadfast love. The story of the two had no beginning, only an ending of parting in death. After his death, he became a demon for her, and fought fiercely with the immortals of the three realms. After he was killed, his unique seven souls were hidden in various places by the immortals; she became a ghost for him, and before she passed away, she smashed Meng Po's soup bowl, and her soul flew away. Even so, he still vowed to subvert the three realms, find her in the next reincarnation, and marry her, even if it took a thousand years.
