[Mystic Turtle saw that you didn't dare to speak and let out a cold snort before soaring into the sky.]
[It was only then that you noticed the massive iron chains shackling the Mystic Turtle.]
[The chains were inscribed with patterns you couldn't understand.]
[The Mystic Turtle finally stopped keeping you in suspense.]
[It told you that everyone here was a prisoner.]
[It admitted that the claim of ten billion Spirit Stones for your release was just to deceive Bai Ruoxue.]
[No one from the Southern Regions could leave the Endless Sea, including itself.]
[The formation gap here was merely a trap.]
[This place was where the spirit of the entire sealing formation resided.]
[Everyone in the sealed land was under the formation's influence, and their auras were sensed by the formation spirit.]
[The Mystic Turtle said that even if it didn't stop you, crossing the formation gap would result in you being struck down by Heavenly Thunder.]
[Only outsiders like Bai Ruoxue, who didn't stay too long in the sealed land, could freely come and go without being sensed by the formation spirit.]
[But if Bai Ruoxue stayed too long, she wouldn't be able to leave either.]
[After hearing the Mystic Turtle's explanation, you broke into a cold sweat.]
[However, you still didn't understand why the Mystic Turtle was telling you all this.]
[You didn't have to guess for long; the Mystic Turtle soon revealed its purpose.]
[It said it didn't want to be trapped here as a gatekeeper.]
[It believed that you might have a chance to break the seal if you achieved the Divine Dao.]
[So, it was willing to invest in you.]
[However, it also said it was disappointed with your recent performance.]
[You awkwardly smiled on the surface.]
[But in your heart, you muttered, "How did I disappoint you? With a big shot like you here, how could I dare to act rashly? Couldn't you have said earlier that we were on the same side!"]
[Seeing your discontent, the Mystic Turtle pointed out that the surrounding area was part of the sealing formation. It hadn't restricted your movements recently, so why hadn't you tried to study and break it?]
[You twitched your mouth and retorted that you didn't even know the basics of formations. How could you possibly learn such a complex formation on your own?]
[In truth, you had thought about studying the sealing formation, given your talent as a Formation Dao genius.]
[But without understanding the basic principles of formations, even the greatest talent would be useless!]
[The Mystic Turtle was stunned by your words.]
[It had never considered that a Chosen capable of cultivating the Divine Dao might not know basic formations.]
[So, to return to Green Hills City, you had to head north.]
[In the twelfth year, you finally saw Green Hills City.]
[What took Bai Ruoxue only a few days took you two whole years.]
[This was despite your cultivation reaching the second level of Core Formation, allowing you to fly.]
[Otherwise, it would have taken even longer.]
[You disguised yourself and rented a small courtyard near the Jiang Family Mansion.]
[In the thirteenth year, you heard a loud noise and knew something had happened to your Jiang Family.]
[You stepped outside and saw a shadowy figure in the sky attacking the Jiang Family.]
[But soon, your father, Jiang Fushan, arrived with a group of cultivators.]
[One of them, a Tribulation Crossing stage cultivator, casually killed the shadowy figure.]
[Seeing the situation in the Jiang Family settle down, you quickly revealed yourself and called out to your father.]
[Unsurprisingly, you followed your father, Jiang Fushan, to Spine Mountain.]
[In the following days, you cultivated at Spine Mountain.]
[This time, your focus was mainly on formations.]
[In the fifteenth year, after two years of cultivation at Spine Mountain, you reached the level of a third-grade Formation Master.]
[Formation Master levels are simple, ranging from first to ninth grade, with the level above ninth being Immortal Formation Master.]
[These basics were all in the memory from the formation jade slip given by the Mystic Turtle.]
[Your rapid advancement to a third-grade Formation Master was not just due to your talent but also largely thanks to the formation jade slip.]
[Previously, you had no exposure to formations and didn't understand them. Now, you realized the jade slip's true value.]
[It saved you a lot of time in familiarizing yourself with various formation theories and basics.]
[The theories and basics of formations were as vast and complex as mathematical calculations and formulas from your previous life.]
[Without understanding them, the path of formations would be extremely difficult.]
[You felt that without the jade slip, mastering those theories and basics would have taken you years, if not decades.]
[In the sixteenth year, you became familiar with the people at Spine Mountain.]
[One day, you approached Old Li and told him you wanted to study the formations left by Senior Lu Wuya.]
[This was your main reason for coming to Spine Mountain.]
[Since you couldn't study the sealing formation for now, you thought that studying the formations left by Senior Lu Wuya, which could avoid Heavenly Thunder, would greatly advance your formation skills.]
