Toaru Majutsu no Index: New Testament - Volume 10, Chapter 17: V.S. “The Master of the Library and the Magic Queen” Round_09.

Genius Neurosurgeon Lǐ Xīnyuàn died while being held at the gunpoint to perform a surgery on a terrorist leader.When he opened his eyes, he had transmigrated into a world similar to a Webnovel he'd been forced to read by a colleague.Now you'd think Lǐ Xīnyuàn had transmigrated into that Webnovel. But did he?No! Instead he'd been transmigrated into that webnovel's spin-off/“what-if” version of the story with nothing but the superficial knowledge of the plot thanks to reading the main novel.Now tasked with the mission of avoiding plotholes, unnecessary dog-blood, death and following the storyline to ensure the male lead's ascension to the throne of Supreme Emperor, he didn't know whether to laugh or cry.And why did no one tell him that his character had to be married into the Male Lead's harem??What about the Female Lead?Later:Lǐ Xīnyuàn: Why doesn't Your Highness spend the night with concubine Yang?ML: Don't want to.Lǐ Xīnyuàn: ... Why?ML: Are you pushing me away?Lǐ Xīnyuàn: QAQ

Liola—the best assassin in his world—has vowed to kill no more. He was being chased by an assassination organization when he accidentally dropped into a parallel universe: through a dimensional gate and into poor teenager Kaiser’s apartment. Instead of going to the government shelter for lost dimensional travelers, Liola and Kaiser wind up going to school together.

Liola has been trying his best to live the life of an ordinary person, but after certain things happen one after the other, he begins to realize that being an ordinary person could be harder than being an assassin.

Liam was a nobody, whether it was grades or sports or appearance or social life. Not because he didn't have a brain but because his luck was just that bad. However, everything changed when a mysterious game called 'Evolution Online' was suddenly launched. The world he knew changed upside down!

There was blood, death, and carnage everywhere. While everyone from small companies and big governments scrambled to get a foothold on this mysterious video game, some people's lives turned for the better and some for the worse.

Liam, unfortunately, being the latter, still somehow ended up at the bottom of the barrel. His insignificant life was squished like an insect and his loved ones were destroyed right in front of him. In the end, he was already dead without ever having a single chance to fight back.

But his story did not end there. Liam found himself returned back to the time before everything began!

Watch as the young man who was once a nobody reaches for the pinnacle of strength and power wreaking havoc on the world that destroyed him once! This time everything will be different!

At the beginning of the 21st century, twelve reincarnations shattered the void and returned to their hometown.

They preach the world and reopen the space of reincarnation.

Then……

“The Republic of East Asia announced that it will fully implement a five-year spell casting and twelve-year simulation mage training policy.”

“The Republic of East Asia has announced a new change in the marriage law, making it legal to marry someone you call upon after meeting the adulthood conditions of your respective race.”

“The Republic of East Asia announced that the East China Military Region No. 1 Mobile Armor Brigade was established, and the special humanoid mecha “Gundam” officially joined the campaign.”

“Congratulations from the United Kingdom on this, the upper hero Arturia Pendragon will visit Shanghai next month”

“In the far east of Japan, the ignition of the wave engine failed, or seek energy assistance from the East Asian Republic.”

“Space cracks have been discovered in the Chernobyl region, alien creatures have ravaged the Chernobyl region, and the Russian Defense Forces have entered the battle.”

Four years after twelve reincarnators changed the world, Li Ping entered his own battlefield for the first time.

PS: Although the introduction is like this… but in fact it is written about two thorns + machine battle + movie + mythical stew…
