Chen Yulu's promise was one that Jiang Xiaobai did not forget.
What he'd promised someone he had to follow through with, after all.
Moreover, Jiang Xiaobai was very curious about the function of the Heavenly Upright Stone.
When there was no one around, Jiang Xiaobai stored Qiongyu in the Seven Treasures Pagoda.
The system directly took Jiang Xiaobai and left the Wood Spirit World.
Then, with the help of a cheat for bringing people along, using only a piece of world origin stone, he and Qiongyu returned to the Wood Spirit World.
It was still outside of the secret realm.
When Qiao Yunshen and others saw Jiang Xiaobai just appear out of nowhere, they were dumbfounded.
"How on earth did you do that?"
Qiao Yunshen's mouth hung open in shock as he circled around Jiang Xiaobai, "You, you have so many secrets."
"Little secrets, little secrets."
