[Out of curiosity, Qian Xunji pressed Bibi Dong for answers, but unfortunately, Bibi Dong was also very curious about what Yu Xiaogang and the others had actually encountered.]
[The Spirit Bone Treasure Map was the only thing she had personally experienced, yet she couldn't speak of it due to her Spirit Oath.]
[Thus, Bibi Dong claimed ignorance to every question, nearly making Qian Xunji double over in anger.]
["You traveled together for so long, and you're telling me you know nothing?"]
["You truly are my good Disciple."]
[Qian Xunji finally spoke with an expressionless face.]
["There was nothing I could do. After all, I only followed them because I was curious about Yu Xiaogang's ten-thousand-year third spirit ring."]
["Besides that, even if I wanted to go, they wouldn't take me along."]
[Bibi Dong spread her hands, wearing a helpless expression.]
["Fine, I won't hold this against you this time. Since you aren't hurt anyway, going out for a walk can be considered a good thing."]
[Qian Xunji nodded, but his mind began to ponder how to probe the secrets of the Blue Lightning Tyrant Dragon Sect.]
[Bibi Dong had clearly guessed that her teacher would do this, so she immediately spoke up.]
["Teacher, let's agree on something first. You can try to find out their secrets from Yu Xiaogang's side, but you cannot use me as the reason."]
[After all, she had taken the initiative to follow them out this time. If her teacher used this as a reason to hold them accountable, then in the future, if she wanted to follow Yu Xiaogang or go out with others again, they could use this reason to reject her.]
["Very well."]
[Qian Xunji was silent for a moment before finally nodding.]
[As the Supreme Pontiff of Spirit Hall, he had plenty of reasons and means; he truly didn't need to use his own Disciple as an excuse.]
[But unfortunately, following the beating from Yu Yuanzhen and the words from his own father, Qian Xunji found that his room for maneuver in this matter had suddenly dwindled.]
[Darker methods couldn't be used, and Yu Xiaogang had withstood both threats and inducements.]
[Thus, the only legitimate reason remaining before Qian Xunji was this one.]
[Consequently, Qian Xunji directly tore up the agreement with his Disciple, making things difficult for Yu Xiaogang by using the very reason he had promised her he wouldn't use.]
["Stand aside. Right now I am the Supreme Pontiff, not your teacher!"]
[Qian Xunji said, casting only a glance at Bibi Dong.]
[Bibi Dong, shouted down by Qian Xunji, clenched her fists, her eyes filled with dissatisfaction toward her teacher.]
[Unfortunately, at this moment she was merely a powerless Spirit Elder, so she could only retreat to the side in the end.]
[From below, Yu Xiaogang saw the dissatisfaction in Bibi Dong's eyes and immediately began to wonder if he should incite her to defect when he took revenge on Qian Xunji in the future.]
[Although Yu Xiaogang hadn't personally experienced what a rebellious child could do, he still knew of many such instances.]
[It's time to perform a backstab on your Supreme Pontiff teacher.]
[Of course, these were all things for the future; the problem to be solved right now was still Qian Xunji.]
["So, His Holiness the Supreme Pontiff is prepared to lock me up directly?"]
["Heh, you can also have your father take you away, I won't stop him. But as long as you still want to learn the knowledge of our Spirit Hall, you must abide by the rules here!"]
[Qian Xunji sat regally upon his throne, tidying the hem of his clothes with an easy expression.]
["Fine, then I simply won't learn for the time being."]
[Yu Xiaogang shrugged and said.]
["Hmm?"]
[Yu Xiaogang's answer was beyond Qian Xunji's expectations, causing his hands to pause in their movement.]
[He hadn't expected Yu Xiaogang would actually choose the first option.]
[Yu Xiaogang's goal in coming to Spirit City was to learn this knowledge of Spirit Hall, yet now he said he wouldn't learn.]
[What did this mean?]
["Are you sure?"]
["Of course. Otherwise, could I possibly go five years without participating in any Cultivate?"]
[Yu Xiaogang spoke with a calm and composed manner.]
[Five years—during this golden age for a Spirit Master's Cultivate, even Yu Xiaogang wasn't sure what level he could reach.]
[As for not being able to study everything regarding the Light Attribute in Spirit Hall...]
[Yu Xiaogang smiled.]
[He had now obtained his fourth spirit ring, and the Spirit Ability Light-Dark Conversion had introduced the Dark Attribute to him.]
[On the way back to Spirit City, Yu Xiaogang had experimented and reached a conclusion:]
[His Light-Dark Conversion was not the type that converted during battle and automatically switched back once the battle ended.]
[This conversion Spirit Ability of his consumed a certain amount of Soul Power to truly and completely convert himself into the Dark Attribute.]
[If Yu Xiaogang did not actively convert back afterward, then he would never return to the Light Attribute again.]
[In other words, if Yu Xiaogang wanted to, he could even start from now, abandon his research on the Light Attribute, and completely pivot to researching the darkness attribute.]
[In reality, although Yu Xiaogang hadn't done so yet, he knew he would definitely take this step in the future.]
[Because Yu Xiaogang had thought of a very terrifying thing.]
[With the Light-Dark Conversion Spirit Ability, and relying on this characteristic of complete attribute conversion, when he added new spirit rings in the future, would he still only be able to continue adding spirit rings from Light Attribute Spirit Beasts?]
[Or perhaps, could he also choose spirit rings from Dark Attribute Spirit Beasts?]
[This question was very much worth pondering.]
[Because it would have an earth-shattering impact on Yu Xiaogang's future spirit ring selection.]
[If it were truly as he hypothesized, and he could choose to add spirit rings from darkness attribute Spirit Beasts, it would mean his spirit ring options had expanded by countless times.]
[More importantly, because they were opposite attributes, there were differences in characteristics between the Light Attribute and the Dark Attribute.]
[These differences were such that the Light Attribute had things the Dark Attribute absolutely lacked, and vice versa.]
[For example, many Light Attribute Spirit Beasts possessed abilities like purification, healing, and enhancement.]
[Whereas Dark Attribute Spirit Beasts possessed functions like curses, erosion, and weakening.]
[If Yu Xiaogang were to give himself a Dark Attribute spirit ring whose Spirit Ability was a curse...]
[Then upon converting to the Light Attribute, with the same Spirit Ability effect but the attribute changed, it would become a Light Attribute curse.]
[Good heavens, whose Light Attribute ever had the word 'curse' associated with it?]
[Of course, being this powerful naturally came with a price.]
[The Dark Attribute was a power completely opposite to the Light Attribute, and its characteristics were entirely different.]
[Once he turned to researching the Dark Attribute, everything he had learned in the past would no longer be applicable.]
[This was a very troublesome matter.]
[It meant that Yu Xiaogang would certainly have to spend a massive amount of time in the future learning and researching everything related to the Dark Attribute.]
[But right now, Yu Xiaogang had too many things on his hands.]
[Research on Self-Created Spirit Abilities, research on Spirit Bones, the Light of Spirit and the Light of Matter, and even the eventual synthesis of the two.]
[If the conversion to the Dark Attribute were added, many of the items listed above would have to be done all over again.]
[Just thinking about it made Yu Xiaogang feel like he was going bald.]
[Besides this, the daily Soul Power Cultivate and the honing of combat experience could not be neglected either.]
[To put it bluntly, Yu Xiaogang could already foresee a future where he would be working non-stop.]
