Chapter 870 - 387: Nascent Soul Relic, Method of Yin Yang Balance

"Once the Ten Thousand Poison Gu fully absorbs that portion of Thousand Poison Marrow, I will let it undergo Crossing the Tribulation in the Fire Cloud Secret Realm," Li Chang’an muttered.

He stored away the Original Spirit Flower and continued inspecting the other Treasures. Half an hour later, he finished cataloging all the items. Li Chang’an ventured deeper into the Treasure Vault and opened another large door. Behind this door lay various Cultivation Techniques, Magic, and Ancient Texts that Wang Songde had acquired over his long years of Cultivation Immortality.

Li Chang’an thought, "Wang Yannian should also have a private Treasure Vault like this. Those Celestial Soul Fruits are likely hidden there. Other than Wang Yannian himself, no one probably knows its location. If he dies, who knows when that vault will see the light of day again."

Li Chang’an could only hope that Wang Yannian had managed to escape with his life. Withdrawing his stray thoughts, he began examining the extensive collection of books. Because Wang Songde’s Spiritual Root differed from his own, the majority of the Cultivation Techniques and Magic were useless to him; they could only serve to expand the collection of Changqing Mountain’s Library Pavilion.

However, Li Chang’an soon discovered a Magic that would be extremely useful to him.

The ’Yin-to-Yang Transformation Skill’.

The concepts detailed within this Magic were astonishingly the path of Yin Yang Balance!

For many years, Li Chang’an had been exploring the Yin Yang Balance. Yi Wood represented Yin, while Geng Metal represented Yang. He wanted to combine the power of the Great Yi Wood Sword Array and the Da Geng Golden Sword Formation to form a Yin Yang Sword Array, allowing both arrays to unleash their most perfect power. To achieve this, he had even utilized the Three-Eyed Bodhi Seed to temporarily boost his comprehension.

Alas, his attempts had always ended in failure.

The path of Yin Yang was profound and mysterious, making it extremely difficult to achieve true balance. Treasures and Magic related to the Yin Yang Balance were exceptionally rare, and he had never managed to find any. He never expected to discover such a Magic inside Wang Songde’s Treasure Vault.

"This can be considered an unexpected delight," Li Chang’an said with a smile. Although his trip to the Wang Family had not yielded the Celestial Soul Fruit, he had successively obtained the Original Spirit Flower and this Magic.

He focused his mind and carefully read through its contents. The philosophy expounded in this Magic was different from his previous concepts. The Yin Yang Balance he had envisioned was one where Yin contained Yang, and Yang contained Yin—a state of both opposition and inclusion. In contrast, this ’Yin-to-Yang Transformation Skill’ was relatively simple; it directly converted Yin Yang Power back and forth to achieve balance.

Li Chang’an thought, "This method is simple and direct, much easier than what I previously imagined. Moreover, the Yin Yang Power can flawlessly merge, pushing the might of the Sword Array to its absolute limit."

He estimated that once he mastered this Magic, his combat prowess would reach a whole new level. Currently, by forcibly merging the two Sword Arrays, his combat strength could already surpass that of a Fake Soul and rival an ordinary expert at the Early Stage of True Soul. If he also mastered this ’Yin-to-Yang Transformation Skill’, he should be able to stand on par with veteran powerhouses at the Early Stage of Nascent Soul.

"From now on, I will make this Magic the focal point of my cultivation," Li Chang’an resolved, storing it into his Storage Pouch.

A few hours later.

He had briefly skimmed through all the books in the vault and selected two Celestial Grade Sword Skills. The first was ’Profound Gold Sword Qi’. Once one achieved Entry-Level proficiency in it, they could unleash extremely tyrannical Gold Element Sword Qi. The second was ’Cyan Feather Sword Qi’, which was similar to ’Profound Gold Sword Qi’, except the unleashed Sword Qi possessed the Wood Attribute.

Li Chang’an planned to use these two types of Sword Qi to replace the ordinary Sword Qi generated by his own Magical Power, further enhancing the might of his Sword Array. By doing so, the entire Yin Yang Sword Array would be composed of five types of Magic, possessing unimaginable power.

"It should be feasible. I’ll test it out slowly when I get back," Li Chang’an murmured. With a wave of his hand, he stored away all the books. Subsequently, he unleashed the Power of Earth Element to fill the Treasure Vault, erasing all traces of his presence.

After finishing all of this, he left the area and returned to Changqing Mountain. As soon as he arrived, he received two pieces of news—one good, and one bad.

The good news was that Wang Yannian’s Nascent Soul had successfully escaped. He had possessed the body of another Wang Family junior and was currently recovering his strength.

The bad news was that the Wang Family was not the only one to suffer a disaster today. The Black Tortoise Sect, one of the four major Sects in the Yuan Country, had also fallen victim to an incident. A Tier Four Demon Monarch from the Black Tortoise Sect had been ambushed by Demonic Nascent Soul experts while out on patrol. By the time reinforcements arrived, they only found countless traces of battle. Back within the Black Tortoise Sect, that Demon Monarch’s Soul Lamp had already been extinguished.

"Which Demon Monarch was it?" Hearing this news, Li Chang’an’s heart skipped a beat. The Black Tortoise Sect had a total of two Tier Four Demon Monarchs: the ’Two-headed Jade Spirit Turtle’ and the ’Purple Gold Red-eyed Flood Dragon’. He certainly didn’t want the Old Turtle to have met with a mishap, especially since he still wanted to trade with him for the Cyan Condensing Jade.

Song Yu’Er informed him, "Senior, I heard that the one who suffered the accident was a Flood Dragon."

"As long as it’s not the Old Turtle," Li Chang’an said, though still feeling somewhat uneasy. He immediately took out his Communication Treasure and established contact with Lin Xuanyan. He asked straightforwardly, "Daoist Lin, I heard something happened at the Black Tortoise Sect. Is Elder Jade Spirit Turtle alright?"

"It wasn’t the Old Turtle. The Old Turtle still has a long life ahead of him. It was the other Demon Monarch senior," Lin Xuanyan informed him.

The one who fell victim was indeed the Purple Gold Red-eyed Flood Dragon. Judging by the traces and auras left at the scene, he had been besieged by no less than a dozen Demonic True Monarchs. Now, much like the Wang Family, the Black Tortoise Sect was no longer at its peak. The remaining Tier Four Power within the Sect consisted only of the Old Turtle and that young Holy Fire True Monarch.

"Today’s incident gave the Old Turtle quite a fright.

"It was originally supposed to be his turn to go out on patrol, but he felt lazy and asked Senior Red-eyed Flood Dragon to take his place. He never expected that Demonic True Monarchs would be lying in ambush outside.

"The Old Turtle has firmly made up his mind that he will never leave the Sect again. He plans to hole up inside the Sect’s Tier Four Array until the end of time..." Lin Xuanyan said, recounting the Old Turtle’s current state.
