Higher life form.
Fate Space.
Mechanical City State.
Alchemy.
And the next steps of obtaining body parts, exploring mysticism and so on.
These topics filled Han Dong's mind as he lay in bed. Unconsciously, several hours had passed. It wasn't until three or four in the morning that he fell asleep.
As a researcher, he was quite captivated by, even obsessed with, 'new things'.
After gaining an understanding of the world's general situation, he was eager to delve deeper into new and unfamiliar concepts at the Knight Academy, topics he would never have encountered in his previous world.
Because he went to bed so late, he woke up much later... disturbed by an argument outside his door.
"What's all the noise?"
Han Dong stretched lazily before eavesdropping from his room.
He picked up a few keywords: 'forced conscription', 'tax collection'.
