“Who are you lady?”

“How rude I am the goddess of reincarnation!”

A normal young man found himself surrounded by thousands of gods who were observing him silently.

“Shit... did I die?”

“yes... I know it must be hard-”

“LET'S GO GIVE ME MY HAREM AND OP ABILITIES LET ME EXPERIENCE COCKY EGOTISTICAL PEOPLE WHO WILL CALL ME TRASH NO MATTER HOW MUCH I PROVE I'M OVERPOWERED!!!”

Dead silence... Thousands of gods were left speechless.

“ok give me my system or infinite magic or unique bloodline or whatever”

Hearing what the young man said thousands of gods burst into laughter.

“I the God of strength will give you my system”

“I the God of life will give you my system”

“I the God of archery will give you my system”

Every single god gave the young man their system/power causing a unique system to be made just for him.

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…
