Baka to Test to Shoukanjuu‎ - Volume 2, The Final Question

Everyone in the entire imperial capital city B knows that, in recent months, there has been a fortune-telling stall with a sky-high pedigree.
Break the marriage, control the universe; talk about misfortune and good fortune, test the secrets of the sky; comment on the eight characters, change the way of luck… simply say that you are alive, you will not die, say that you are dead, you don’t want to live!
The reason why anyone with a head and a face knows it is because the head and face naturally feel that the magic stick cannot be placed on the table and cannot be seen.
However, the wind has changed recently. It is said that the famous Bai family of the Junhong family has sought a famous magic stick for the youngest son of the sick jar!
Unexpectedly, the magic stick was very pretentious and deadly, and only said one sentence.
“I miss him, unless I marry him. Otherwise, within three months, he will surely die!”
So, the whole emperor was in an uproar.

In the 30th century, Tyler Rustel is an eccentric and visionary genius, renowned as a brilliant inventor. His life, however, comes to an abrupt end when a small experimental nuclear reactor explodes in a series of unforeseen events. Yet, death is not the end for Tyler. He awakens in a body that feels both familiar and foreign—a parallel version of himself in a completely different universe.This is not a world of technological progress or orderly civilization. Here, twisted gods roam the cosmos, shaping realities according to their cruel whims. The moral laws that governed his previous world do not exist. This is a magical universe, one marked by brutal betrayals, interdimensional wars, and endless massacres. The balance between the forces that rule this cosmos is fragile, and Tyler finds himself at the center of schemes involving powerful entities and boundless ambitions.However, Tyler is no longer an ordinary man. Upon awakening in this new world, he discovers that a fragment of his technology has survived with him: an advanced artificial intelligence system capable of analyzing, adapting, and enhancing anything, provided it has the necessary data. From magical weapons and arcane spells to alchemical techniques and enchanted jewelry, everything can be optimized under his supervision.Armed with this technological advantage in a universe dominated by magic, Tyler quickly realizes the potential of his unique position. While others struggle to survive, he schemes to conquer. Driven by his sharp intellect and a questionable sense of morality, Tyler embarks on a ruthless campaign to achieve magical supremacy and subjugate all worlds around him. He seeks neither redemption nor alliances. His ambition is clear: to rule everything and everyone as a tyrant, to amass an immense harem of women, and to father one million children to establish his legacy across all realms.

After transmigrating to many worlds:

MC: Come out system!!! The heck?! Why do these MLs not love their female goddesses, but insist on doing it with me! Aaaaahh!!!

System: …. __(:3」∠)_ Don’t ask me, I also don’t know.
