[A non-human protagonist + the Fourth Calamity + farming management + behind-the-scenes plot + group portraits + search-and-fight] Le Ang, caught in a summoning ritual by a descendant of a noble, travels back in time as a gray rat hiding in the basement of a noble mansion, unexpectedly gaining the ability to summon players from Blue Star. Upon seeing the virtual reality game's realism, the Blue Star players, whose consciousnesses were summoned, become obsessed with their respective in-game characters—rats. As the game planner and the NPC boss to the rat players, Le Ang, while expanding his power through the supplies brought back by the players, learns extraordinary knowledge of this world from the descendants of the nobles... Gradually, Le Ang discovers that he has mastered alchemy. He transforms the frail rat players into his own creations. Flying squirrels with bat wings, muscular giant mutated rats...

Pursue knowledge, question rules, and seek truth.

This is the world of wizards.

Angele stumbled into this world with the [Book of Truth].

Many years later.

Angele put his hand on the shoulder of the editor-in-chief of the journal "Truth".

"There used to be two dark clouds floating over the floating city called knowledge. I'm glad that I have completely cleared them out."

"I just burned their manuscripts and used magic to make the world forget their names. How can you say that I killed them?"

...

"Your accusations against my thesis are completely nonsense! This is academic oppression!"

"For stupid people, I will forgive your incompetence and give you more time to reproduce my experimental results."

"Truth? I am the truth! You ancient wizards, it's time to end."

"The world is about to be reshuffled. I want to see if you can still be at the table this time!"

Angele, the king of all laws, the founder of truth, and the gravedigger of the old times, said so.
