Archery

While other saints can only scramble for ether fragments to bitterly increase their cultivation due to the severe lack of quintessential ether; the substance left behind after the destruction of a mature celestial body, achieving divinity in the Core Mainland is actually much more arduous than in a normal stellar world.

Leonardo thought that it was no wonder why major powers would protect the livelihood of planets that had achieved maturity, they probably harvested their quintessential ether in the dark. He couldn't help but worry about Arcadia's future, but then again he realized that it would take at least a few thousand years for the will to mature and by then, everyone he cared about would have already aged enough to die a natural death. Thus, he calmed down. 

However, he also knew that Wendy's co-soul treated Arcadia as a daughter, and it was very possible that Wendy would go back to the stellar world in the event of someone targeting Arcadia.
