Zhao Changhe sat cross-legged in what used to be the bridal chamber, contemplating the introductory cultivation technique sent by Ying Wu.
Regarding Ying Wu's invitation to fight in the Secret Realm, it was purely for combat, and there was no need to study space beforehand. However, Ying Wu still insisted that he learn it first, not for this battle but clearly to aid him later in dealing with Jiuyou.
Because the space around Jiuyou must be chaotic; without learning the ways of space, forget about finding people within a month, even a hundred years won't suffice.
But the place Ying Wu wanted to fight had nothing to do with Jiuyou; they were two different matters. Why teach him this first instead of helping him finish his battle and then teaching him?
It could only be because Ying Wu was not certain he would make it out alive, worried he might perish inside, thus settling everything in advance.
