Huang Jiao, the Immortal Person, if he wanted to grow up into an adult capable of causing disturbances, would need at least twenty years, even with others' help.
Did he think he was Nezha? Born able to run and jump?
Impossible. Under the current circumstances, if Huang Jiao, the Immortal Person, acted ordinarily, it would still be fine. But if he were like Nezha, showing extraordinary signs from birth, it wouldn't be long before he was found by Jiang Chen.
And then, there would be no "and then." Once they found the reincarnated Huang Jiao, could Jiang Chen possibly leave him be?
"I overlooked something. If Huang Jiao wants to grow up safely, he must appear no different from ordinary people during his youth. Only in this way would he not attract attention."
"Once he comes of age, someone will surely lead him into the Dao. Only then can the plan of the Earth Dao Country proceed."
