Chapter 66: 65. Transforming into Rainbow (5.2K words - Please subscribe) [You begin cultivating "Profound Transformation Sword Manual"] [Like the "Profound Qi Guiding Technique," the "Profound Transformation Sword Manual" is merely a technique for absorbing Profound Qi. You only need to follow the guidance for regular cultivation, without the distinction of Xiaocheng or Great Success] [Ten years later, your Profound Qi has not increased, but you feel that a trace of Sword Intent has been nurtured within your Divine Soul. That trace of Sword Intent is mysterious and intangible, yet you can sense that your Divine Soul is indeed becoming sharper] [One hundred years later, as usual, you visualize the Heaven-Reaching Divine Sword, seeing only the sword’s body beneath the clouds, not its tip. In your heart, a strong, indefinable emotion is born. The surging Sword Intent begins to merge with the Spirit you nurtured over three hundred years through the "Cold Prison Floating Life Bracelet," causing those Spirits to seem to take shape. The sword tip slowly forms from your accumulated Spirit, eventually piercing the sky, dispersing the clouds, becoming a complete Heaven-Reaching Sword] [You have comprehended the ultimate Secret Technique of the "Profound Transformation Sword Manual"—Human Sword Unity] In the Cave Mansion’s study, Song Yan came to his senses and slowly put down the animal skin he was holding, looking at the Flying Sword on the other side. Previously, even though he possessed this ownerless sword, it was still "the sword is the sword, he is he," with no connection between the two. When he controlled the sword, it was like a child picking up a brick, wielding power in vain, not able to unleash deeper power. He reconnected his Profound Qi to the Flying Sword. This time, he felt his Divine Soul merge into the Flying Sword in a peculiar way. The Flying Sword burst into a brilliant light, his figure moved, and he merged into that light, shooting out like a long rainbow with a slight movement. Fortunately, Song Yan only used a little power and kept enough caution, so the rainbow swiftly rotated dozens of times in the study before settling down. The radiant light dissipated, and the person and sword separated again. This time, the person is the person, and the sword is the sword. Yet, with a single thought, Song Yan merged with the Sword’s radiant light again. In this instant, he felt more. He became stronger because of the sword, and the sword became sharper because of him. Song Yan closed his eyes, pondering carefully for a long time before understanding. ’So that’s how it is...’ ’Whether it is Flying Sword, paper figure, or shadow puppet, they all involve the cultivator’s Divine Soul to some extent.’ ’However, the three have their differences.’ ’A Flying Sword involves complete fusion with the sword, enhancing both the sword and the person, but if the sword is damaged, it can harm the person as well. Because it is Human Sword Unity, the person and sword cannot separate. Wherever the person is, the sword is there too.’ ’A paper figure involves splitting a wisp of the Divine Soul into the paper figure, and no matter how strong the paper figure becomes, it won’t affect the main body. If the paper figure falls, the main body merely retrieves that wisp of the Divine Soul, harmlessly. It’s much safer than Human Sword Unity. And because the paper figure is entirely a part of the main body’s Divine Soul, it cannot stray too far from the main body.’ ’Originally, shadow puppets did not involve the Divine Soul, but were controlled externally. Their strength depended entirely on the shadow puppets themselves. If no control is imposed, a shadow puppet does not become scrap metal like a Flying Sword, nor does it go out of control like a paper figure, as there are inherent evil souls within them, driven by those Evil Souls. This can be well demonstrated in the current Evil Land. The Stone Seat Elder was indeed talented, using the Painted Skin Divine Physiognomy to simulate myriad forms, and then merging a wisp of Divine Soul into the shadow puppet, achieving a paper figure effect. However, shadow puppets are more dangerous compared to paper figures. Because a paper figure holds only a wisp of the main body’s Divine Soul, while the core of a shadow puppet is an invited Evil Soul, posing the risk of backfire if the merging is improper. That’s why the Stone Seat Elder values Divine Physiognomy so much. If you haven’t grasped the true essence of Divine Physiognomy, it becomes challenging to safely handle the shadow puppet’s Divine Soul, increasing the risk of backfire during merging. ’But I... can spend thousands of years, utilize Evil Qi, to perfect the "Skin Painting Soul Summoning Technique," turning Summoning into Slave Soul, then into Deformed Soul. While others cautiously avoid the backfire risk when merging the Divine Soul into a shadow puppet, I need not worry. Because the invited Evil Soul is already under my control. Therefore, I can control a shadow puppet from thousands of miles away, like an avatar, with just a bit of Divine Soul.’ ’This is quite the... BUG...’ Song Yan snapped his finger gently, and the Flying Sword fell lightly back into its sheath. ... ... [You begin cultivating the "White Snake Sword Technique"] [Seven years later, you perfect this Magic] [Forty years later, you deduce a Single Mutation spell, "Profound Snake Sword Technique"] [Seven hundred and twenty-five years later, you deduce a Secondary Perfect Mutation spell, "Black and White Double Evil"] To this point. The deduction ends. Song Yan glanced at the panel. His lifespan changed from [27/5947] to "[27/5122]". He closed his eyes and slightly perceived the newly comprehended Magic. If the "White Snake Sword Technique" involves merging one’s Profound Qi and Divine Sword Intent into a Flying Sword, attacking like a serpent and slaying enemies, Then the "Profound Snake Sword Technique" forms a layer of Evil Qi on top of this Profound Qi, greatly enhancing its power, turning the white rainbow into a black one. And the Perfect Mutation spell, "Black and White Double Evil," is an elevation of two Single Mutation possibilities. It requires a certain level of Spiritual Power, and with sufficient Spiritual Power, the number of Flying Swords Song Yan can control increases from "one" to "two." Two swords unsheathed, one is an enhanced version of the Profound Snake, thus called Black Death, and this sword can be driven by Evil Qi without the person merging with it;
