Nine Yin Manual

As Lin Feng exerted force with both hands, the saber and sword struck each other with a piercing metallic clang. They broke apart at the sound. The instant they snapped, a torrent of information flooded into Lin Feng's mind, and he directly entered a state of deep meditation. His saber and sword martial souls were also retracted into his body as he entered deep meditation.

At the very instant that piercing sound rang out, Lin Lan and his wife rushed into Lin Feng's room. What they saw upon entering was their son already sitting there with his eyes closed in meditation. The couple exchanged a glance and tacitly said nothing, merely standing quietly beside their son as they waited for him to finish meditating and awaken.

Before long, Lin Feng awoke from his meditative state. Just as he had predicted in the Underworld, Heavenly Sword and Dragon Slaying Saber matched the original setting and had also been integrated with the Douluo World. Unlike the abridged, quick-learning essentials of the Nine Yin Manual and Eighteen Dragon Subduing Palms Zhou Zhiruo had obtained after the saber and sword struck each other, he had received the complete versions of both techniques, along with the complete military treatise General Mu's Principles of War. Back in the Underworld, Lin Feng had wanted to make a bold gamble. He had wagered that Heavenly Sword and Dragon Slaying Saber would retain its original setting, which was why he had asked King Qin Guang for the Divine Medicine King Chapter; otherwise, he would actually have wanted a top-tier technique. His thinking then had been that if he won the gamble, the Nine Yin Manual, Eighteen Dragon Subduing Palms, General Mu's Principles of War, and Divine Medicine King Chapter would be enough for him to roam freely across Douluo Continent. Even if he lost, with his Twin Martial Souls, Innate Full Soul Power, cultivation of this world's techniques, and the "world script" he carried, reaching Titled Douluo would not have been difficult. Fortunately, this time, his harvest was exceedingly rich.

The moment he opened his eyes, before he could even rejoice, his mother grabbed him. "Feng'er, are you all right? What happened?"

Lin Feng's face was full of excitement. "I'm fine, Mom. I obtained another tremendous opportunity!"

Hearing this, Lin Lan and Hua Jieyu both looked at Lin Feng questioningly. "Dad, Mom, sit down first and listen to me." Lin Feng pressed his parents down onto the stools in the room.

"After I returned to my room just now, I summoned the Heavenly Sword and Dragon Slaying Saber because I wanted to study my martial souls more carefully. When I held the Heavenly Sword and Dragon Slaying Saber at the same time, a thought surfaced in my mind: I had to make them strike each other. The urge was incredibly strong. I wanted to suppress it, but I felt like I couldn't. So I thought that the worst possible outcome would be both weapons breaking, while I suffered a little injury from damage to my martial souls. I could recover from the injury, and once I recovered and summoned my martial souls again, the sword and saber would be whole again. So I gave it a try. The instant they broke, I felt countless pieces of information pouring into my mind, which forced me into meditation. After waking up, I discovered three more books in my mind. One is a meditation cultivation method called the Nine Yin Manual, one is an inheritable Self-Created Soul Skill called the Eighteen Dragon Subduing Palms, and the last is a military treatise called General Mu's Principles of War. I haven't had time to study them in depth yet, but after looking over the general outlines of the three books, they should all be top-tier inheritances in this world."

Lin Lan and Hua Jieyu had yet to recover from the shock of their son's Twin Martial Souls when an even greater shock struck them. This day was destined to be unforgettable for the rest of their lives.

The couple opened their mouths, wanting to say something, yet not knowing what to say. Should they remind their son not to spread the news? They had already reminded him when he obtained the Divine Medicine King Chapter. Over the past few years, they had come to understand that their son was far more mature than children his age and knew what mattered in every situation. There was no need to remind him of this. Their son would not be foolish enough to go around telling others.

Before the couple could speak, Lin Feng continued, "Hehe, Dad, shall we divide the work again and copy them out?" Could six-year-old Lin Feng write by himself? Of course he could. But copying secret manuals was such grueling work, so it was better left to his father. What bad intentions could a son possibly have? He simply could not bear to let his mother work so hard, nor did he want to tire himself out. His father was in the prime of his life, making him the most suitable person for the job.

Before Lin Lan could reply, Hua Jieyu made the decision. "Fine. You two can start right now. I'll prepare something tasty for you father and son. You can eat while you work." Yes, she would prepare something tasty. Lin Feng would eat while Lin Lan worked.

Lin Lan was speechless for a moment, but since his wife had spoken, he did not dare resist. He ruffled Lin Feng's hair. "You brat."

The father and son began with the Nine Yin Manual, and once they started, they were shocked yet again. The Nine Yin Manual contained eight major chapters. Any single chapter was enough to stand supreme in the Douluo World, while the complete manual could be called a God-Level Inheritance in this world.

The first chapter, the Internal Energy Chapter, was the core of the Nine Yin Manual. Cultivating this internal art could greatly increase one's Internal Energy cultivation, creating a solid and profound foundation. Internal Energy would grow rapidly and remain exceptionally pure. Naturally, in the Douluo World, it had been altered into Soul Power cultivation. Furthermore, the Nine Yin Manual was an orthodox Daoist cultivation technique: upright, peaceful, broad, and profound.

The second chapter, the External Martial Arts Chapter, contained formidable techniques such as the Nine Yin White Bone Claw, Heartbreak Palm, and White Python Whip Technique. Beyond those, it included many other exquisite combat arts, including fist techniques, palm techniques, leg techniques, and grappling methods. In this world, they had been changed into Self-Created Soul Skills, and all could be passed down. One had to know that in Master Jin's stories, Madam Mei and Madam Zhou had not obtained the internal arts, yet merely through reluctantly cultivating the Nine Yin White Bone Claw and going astray, they had both become first-rate experts. Its power was evident.

The third chapter, the Lightness and Vertical Leap Technique, contained supreme movement arts such as "Soaring Leap" and "Snake Movement and Ferret Flip." It allowed one to dodge and maneuver with extreme agility even in confined spaces, while greatly increasing speed during long-distance travel. It was a level above Tang San's Ghost Shadow Perplexing Step.

The fourth chapter, the Healing Chapter, specifically explained how to use Internal Energy or special methods to treat internal and external injuries. In the original story, Hong Qigong, Prince Duan, and Guo Jing had all relied on this method to heal themselves. It was practically capable of bringing the dead back to life.

The fifth chapter, the Acupoint Striking and Sealing Chapter, contained extremely profound acupoint-striking techniques and corresponding methods for undoing them, involving a deep understanding of meridians and acupoints.

The sixth chapter, the Soul Shifting Great Method, resembled a powerful spiritual hypnosis technique. It used spiritual strength to suppress the opponent's mind and will, and it was also an excellent method for cultivating Spiritual Power.

The seventh chapter, the Breath Holding Secret, allowed one to hold one's breath and survive for long periods underwater or in special environments.

The eighth chapter, the Muscle and Bone Strengthening Chapter, was a cultivation method for strengthening tendons and bones and improving one's aptitude. Practicing this chapter could make one's tendons and bones tough and resilient, enhance one's foundation and potential for martial arts, and compensate for deficiencies in one's innate physique.

Only after reading the complete Nine Yin Manual did Lin Feng truly realize what it represented. When he had initially drawn Heavenly Sword and Dragon Slaying Saber as his martial soul, he had guessed that it should contain these two techniques. Back then, he had simply been happy to possess the Heavenly Sword and Dragon Slaying Saber he had loved since childhood, thinking that he had a chance to walk a path that had existed only in fantasy. He had even secretly delighted that his standard setup surpassed Tang San, the world's protagonist. Yet he had never deeply considered its value, especially its value in this world.

Setting aside a top-tier martial soul like Heavenly Sword and Dragon Slaying Saber, the Nine Yin Manual alone would be enough to change the entire Douluo World if word of it spread. This world revered martial souls above all else. Powerful Spirit Masters were the law of this world. If one awakened a useless martial soul, one was nothing, and how far a person could go depended almost entirely on their Innate Soul Power level. Take Yu Xiaogang, for example. If he had not obtained the Immortal Herb Tang San gave him, he would never have reached Level 30 in his lifetime.

Yet the Nine Yin Manual could not only allow people without Soul Power to cultivate, but also improve their aptitude, increase their cultivation speed, and enable ordinary people to reach the level of geniuses. Moreover, the powerful martial arts it contained could free people from the limitations imposed by their martial souls. No matter what martial soul they possessed, they could become powerful Battle Spirit Masters. With the Nine Yin White Bone Claw alone, Ning Rongrong could probably easily cripple Dai Mubai.

In other words, a single Nine Yin Manual could mass-produce countless all-rounder Prodigy Spirit Masters who combined the Assault System, Agility System, Healing System, Control System, Spiritual System, and more. With such conditions, it was practically a direct route to becoming a Titled Douluo.

The value of Heavenly Sword and Dragon Slaying Saber combined with the Nine Yin Manual was incomparable even to a God-tier Spirit like the Six-Winged Angel. Other than its advantage of Innate Level 20 Soul Power, it had nothing else worth comparing.

Even a powerful martial art like the Eighteen Dragon Subduing Palms, renowned throughout Master Jin's universe, now seemed far less astonishing.

In the end, Lin Lan left Lin Feng's room in a daze.
