Once everything had stabilized and the laws of that world began to evolve, Red Cloud first took the instructors and students back.
The evolution of those laws would take quite some time. Of course, for most long-lived beings of the Primordial World, that amount of time was truly nothing.
But for newly born humans, it was indeed rather long.
Kong Xuan, who had already reached Great Luo, chose to remain. The evolution of Great Dao laws at the birth of a world would be of great help to his cultivation and comprehension.
Although, if he cultivated according to the Three Corpses Severing Method, he should have been comprehending emotion-related Great Daos at this time. That would make it easier to sever his first corpse.
But opportunities to witness the opening of heaven would likely be rare in the future. If he missed this chance, who knew how long he would have to wait for another.
As for attaining the Dao and opening heaven himself one day, Kong Xuan might be proud, but he did not dare to hope for it lightly. After all, it was something even his parents had failed to achieve. Even Feng Yi, the current chief of their Phoenix Clan, had yet to comprehend a Dao that belonged solely to her.
Zhao Gongming and the Three Firmaments also chose to stay, though it was their master, Red Cloud, who made that choice for them. Although their cultivation had not yet reached Great Luo, they were already at that threshold. Moreover, after watching those Great Dao laws evolve, they had all entered a state of enlightenment.
Red Cloud also hoped that they could use this opportunity to step into Great Luo. Thus, after leaving behind a Dao avatar to watch over them, his true body took everyone back.
