Runeterra, from Scavenging to Becoming King

Lin Yue has a secret. He can peek into the cracks - a broken sword under the walls of Demacia, a half-volume map buried in the ruins of the Noxus battlefield, a crumpled blueprint in the trash can of Piltover Laboratory... As long as he wants to, he will put his hand in and things will come out. When others traveled through time, they signed in to the system and the master taught them the skills. For him, when he traveled across time, he was picking up rags across city-states. Get a leaf from Ionia today, a bottle of reagent from Zaun tomorrow, and if you're lucky, you can get a meteorite fragment from Mount Targon. Relying on this skill, he picked up the first camp in the ruins of Rune Continent, picked up various partners, and found businessmen from major city-states lining up to ask for cooperation. Noxus wanted him to become an officer, Demacia wanted him to sign an exclusive agreement, and Piltover offered exorbitant prices to buy his secrets. Lin Yue didn't show off too much, just because he kept the most bizarre secret in Rune Continent, which was his own life experience. Until one day, he put his hand into the crack and touched something cold. When he pulled it out, he saw a palm-sized stone with a symbol carved on it. A blue-skinned bald old man appeared behind him out of thin air. "Son," the old man said, "I have been looking for what you are holding for five hundred years." Lin Yue looked down at the stone, then looked up at the expanding crack in the void behind the old man. "Then..." He swallowed, "A partnership?" From that day on, there was a new kingdom in Runeterra.
