The two might be able to spark some fireworks, and Yu Liang's universe just so happened to be able to regulate the Scene Cards participating in the simulation, jumping forward a hundred years to see what Smile Moon would become.
There would be two possible outcomes, one being that Smile Moon fails to become the Lunar Source, necessitating some adjustments from Yu Liang before re-entering it into the simulation.
As the owner of a universe, Yu Liang could try again without limit, which, to some extent, also corresponded to the Moon's ability of Retrospection.
The other outcome would be that Smile Moon officially becomes the Lunar Source over a century within the Scene Card.
This meant that as long as Yu Liang returned Smile Moon to Wangcheng City, allowing it a hundred years, the Smile Moon after a century could officially become the Lunar Source.
This period was a necessary causal condition for Smile Moon to become a Genesis Strange Story.
