Passing down the Great Divine Technique of Inverted Yin and Yang to Xu Erniu was a decision that Zhang Chen had long made in his heart.
Xu Erniu practiced the Alchemy Dao and was manipulated by the Longevity Ancestor, becoming a Grass Returning Pill. If Zhang Chen were to teach Xu Erniu the Great Divine Technique of Inverted Yin and Yang, and Xu Erniu succeeded in cultivating it, could she reverse the properties of the Grass Returning Pill within her body?
There was a hint of anticipation in Zhang Chen's eyes. The path of the Grass Returning Pill was not easy. This Grass Returning Pill was hardly any less valuable than Longevity Flesh, and many had coveted it, leading to constant peril along the way. A slight misstep could result in death and the end of one's cultivation. Zhang Chen did not want Xu Erniu to tread this path. If she could invert Yin and Yang to alter the inherent nature of the Grass Returning Pill, and forge a new path for it, wouldn't that break the shackles?
As for whether Xu Erniu could comprehend the Great Divine Technique of Inverted Yin and Yang, Zhang Chen was not concerned. One must know that Xu Erniu's Alchemy Dao involved harmonizing Kan and Li, controlling the interplay of laws throughout her body. For Xu Erniu, her alchemy practice was an exploration of Yin and Yang, and being a Grass Returning Pill herself, she had a great success rate in understanding the inversion of Yin and Yang.
Moreover, wasn't there Zhang Chen to guide her?
Although Zhang Chen had not mastered Inverted Yin and Yang, after listening to the mantra passed down by the Innate Peacock, he gained some understanding and had many insights into the Dao of Yin and Yang, so he could provide some guidance to Xu Erniu.
"You're passing down Divine Techniques to me? What Divine Techniques do you have?" Xu Erniu was surprised to hear that Zhang Chen wanted to teach her the mantra of a Divine Technique. "You haven't even cultivated Magical Power, so how would you have Divine Techniques? How will you teach me?"
Zhang Chen calmly smiled at her words. "Heh, you must have seen some of my skills at the foot of the mountain. Why view it with ordinary eyes?"
Saying this, Zhang Chen patted Xu Erniu's head with a smile. "You should trust me."
Xu Erniu obediently nodded. "You're right. I should trust you."
Zhang Chen took Xu Erniu to a secluded hall and whispered to her, "The Divine Techniques I'm passing to you are of great significance. Not even the Ancestral Master should know about it. Only you should know about this Divine Technique; a second person must not know that you've mastered it."
Xu Erniu obediently nodded, "Zhang Chen, I'll listen to you. Please pass down the mantra to me quickly."
Seeing Xu Erniu so obedient, Zhang Chen, while feeling sorry for this poor girl, passed down the mantra of Inverted Yin and Yang.
The mantra of Inverted Yin and Yang consisted of exactly thirty-six lines. With Xu Erniu's intellect along with her present accomplishments in cultivation, memorizing these thirty-six lines was hardly difficult.
"Zhang Chen, this mantra is so profound. I don't understand it at all." Xu Erniu memorized the mantra then blinked at Zhang Chen with an innocent look in her eyes.
"Don't worry, let me explain it to you."
Zhang Chen began explaining the mantra to Xu Erniu. For parts he didn't understand, he directly asked the Innate Peacock within the Five-Colored Divine Light. With the Great Freedom Celestial Demon watching, Zhang Chen wasn't worried the Innate Peacock would mislead him with false explanations.
Zhang Chen spent a full three days explaining all the mantras before asking, "Have you memorized them all?"
Xu Erniu rubbed her head and smiled foolishly, "Of course, I memorized them, but I don't quite understand completely."
"Take your time to ponder over them. There will be a time when you gain enlightenment." Zhang Chen patted Xu Erniu's head and casually dismissed her before turning his attention to the Five-Colored Divine Light. "I say, Ancestral Master, it's time for you to pass down the Five Elements Escape Technique to me, right?"
The Peacock sighed slightly at his words. What choice did he have at this point? After all, he needed something from Zhang Chen; he couldn't expect the horse to run without feeding it. He consoled himself, "It's just the Five Elements Escape Technique, a minor technique, not worth mentioning."
Then he spoke to Zhang Chen, "Young one, I'll pass down the Wonderful Technique to you, so you must listen attentively. I'll only teach it once. Whether or not you can memorize it and to what extent you understand it all depends on your own Creation. If you lack that Creation, you can't blame me."
As he spoke, the Peacock wasted no time and passed down each word of the Five Elements Escape Technique to Zhang Chen.
The Five Elements Escape Technique consisted of twenty-five lines, each elemental escape technique comprising five lines of mantra.
The Old Peacock was generous, explaining each line of the Five Elements Escape Technique.
Having received the mantra, Zhang Chen found the Five Elements Escape Technique extremely esoteric. With his current realm, studying this technique was as challenging as reading a Celestial Book. Much like relativity, without sufficient knowledge, even if someone explains it to you, you won't understand.
Only regarding the Water Escape Technique did Zhang Chen gain some insight due to mastering the Water Control Technique, but fully comprehending it was still impossible.
"It's so difficult," Zhang Chen sighed softly after pondering for a moment.
The laws involved in the Five Elements Escape Technique were extremely complex. The primary principle was to transform oneself into the Qi of the Five Elements to escape within them.
For instance, if Zhang Chen wanted to practice Water Escape, he would need to transform himself into a Water Qi, enabling him to traverse through water. However, to say one transforms into Water Qi isn't entirely accurate; it should be termed 'Water Qi.'
As humans are of flesh and blood, turning into Water Qi is extremely difficult. It is a process of material transformation—complex and dangerous. A slight mistake could lead to death and the end of one's cultivation.
For example, during the transformation into Water Qi, if the Qi suddenly becomes unrestrained and disperses, it would result in immediate death and the end of one's cultivation.
