The World Tree truly deserves its name as the Divine Tree capable of birthing worlds, its heart of the tree is essentially a universe unto itself, filled with innumerable stars, and thus, innumerable small worlds. The constant expansion of the Three Realms draws its source from these endless stars.
Infinite stars, with endless stellar power. Creating, expanding, and developing worlds with the power of the stars, this is the fundamental reason why the World Tree can nurture and evolve the Three Realms.
Wukong truly admires the Ancestor of Dao, Hong Jun, for finding the sapling of the World Tree from who knows where, and for the mental effort it must have taken to cultivate it to today's extent. He earnestly hopes that one day he can meet the Ancestor of Dao and earnestly seek his teaching!
But before that, Wukong must elevate his cultivation to the level of a Heavenly Dao Saint. Otherwise, how would he be qualified to meet the Ancestor of Dao?
