Wenren Sheng noticed the medieval world.
This was a place his Mystery Seekers had visited before.
He had already severed its connection to the Eastwater Fragment World. Now, using the contact method provided by the Patrol Division, he was observing the changes here once more.
He saw a school where modern astronomy had begun to be taught.
It had existed before, in fact, because astronomy was connected to divination.
But it had not been established as an independent subject.
Now it had.
"The stars do not move around the Earth. They move around the Sun, and the Earth moves around the Sun as well. This explanation makes it much easier to understand the changes in the star charts across the four seasons," an old man lectured in class.
"This is Heliocentrism."
"Teacher, what you're saying contradicts the Church. The Church says that God created all things with the Earth at the center. The Earth is the center of all things, the center of the starry sky," a student stood and said.
"Oh, is that so? Perhaps it is," the old man said with a smile.
In the countryside.
Several numb Old Farmers were laboring desperately in the fields, drenched in sweat.
At the edge of the fields stood the overseers employed by the lords, watching them with whips in hand.
Whenever someone worked too slowly, he received a lash.
They were serfs. They owned no land of their own. Even the thatched huts they slept in and the straw inside them did not belong to them.
They merely lived numbly, until one day they collapsed headfirst from exhaustion. Expecting a funeral was impossible.
Their corpses were dragged to roadside ditches and tossed aside.
In the dark Middle Ages, people did not even understand how easily this could cause plagues.
