In his memory, Ye Lan sacrificed a lot to complete this plan.
The first was the World Origin, which he found in the Profound Dust Realm when he was punished and sent to the lower realm. Others couldn't recognize it, but he immediately recognized it as the World Origin, which became the first step in his plan.
As for forgetting about karma, that was also his handiwork. Only by forgetting everything and removing all karma could he avoid being detected by the world's reincarnation. Those people would think he was an ordinary baby, allowing Sun Wukong to take him and survive.
He knew Sun Wukong would use the World Origin to open the channel to the Cyan Heaven Immortal Realm and modify it to become the most popular game of the time, thus reasonably allowing people to start cultivating.
