Liu Qian's voice was cold. Chai Yi took a deep breath, as if grasping a life-saving straw: "Ghost grass, a cursed thing, cannot take root and sprout in ordinary soil at all." My uncle, as a wizard, was immersed in practicing black magic all day long, and he often sent people to harvest ghost grass in the shadows, and also tried to plant it in Kakosa, but it all failed. But one day, when he cleaned up my father's faction and exposed countless corpses outside the city, those once withered ghost grass seedlings began to grow after sucking blood... The growth of ghost grass comes at the cost of death..." Liu Qian's pupils contracted suddenly. This answer was like thunder exploding in his mind. In an instant, countless clues were connected. Why does the ghost grass only exist in the river valley of the shadow land and the ruins of Valyria? The apocalypse of Valyria, hundreds of millions of living beings died in an instant, doesn't that monstrous death provide the most fertile breeding ground for the ghost grass? And in the shadowy land overgrown with ghost grass, what scale of death has occurred in the past? Chai Yi saw the shock and thought flashing in Liu Qian's eyes, and knew that she had made the right bet, so she immediately threw out another heavier chip: "And my lord, your black stone..." Liu Qian's gaze instantly became extremely sharp: "Do you know my black stone?" " Chai Yi nodded, his voice trembling slightly: "Because my uncle, the usurper wizard of Kakosa, also has a huge black stone that is almost exactly the same as yours." " Rumble! Liu Qian was shocked. The exact same black stone? How is this possible? His stone comes from the ruins of Valyria, the wizard of Kakosa, how could he also own one? "Where did his black stone come from?" Liu Qian's voice was low. Chai Yi didn't dare to hide it at all, and said very quickly: "This matter is a long story, when my father was still ruling the Hidden Sea, my uncle was addicted to forbidden black magic, and he went to Asia to learn dark tricks from those shadowbinders. Later, he was exiled by my father in anger for conducting inhumane living experiments on civilians in Kakosa and exiled to the gray wasteland, where we all thought he died in that Jedi, but..." Chai Yi's voice was full of pain: "Just one night a few years ago, he came back, wearing a tattered yellow robe and a pale mask on his face, and the most terrifying thing was that he brought back a huge black stone, which was very similar to yours, and his power became extremely terrifying, and my father was killed by him with the most evil black magic on that night. " Her eyes were filled with tears of hatred: "Later, this demon was on the shore of the Hidden Sea, consuming countless people's lives to build a huge palace deep into the sea, he sank the black stone into the deepest part of the palace, and since then, he has stayed in the cold and dark underwater palace almost all day long, with that black stone as his company, delving into those blasphemous dark tricks, and the people of Kakosa trembled in fear..." Liu Qian's heart lake set off unprecedented stormy waves. The wizard in yellow, who returned from the gray wasteland, sank the black stone to the bottom and hid underwater all day to study... All this points to a creepy possibility, and the wizard is probably also trying to decipher the mystery of the black stone. Moreover, the way he chose was to put the black stone underwater, which was completely different from the way Liu Qian and Janice studied. Is water some kind of medium? Or some kind of stimulation condition? What secrets does that black stone hide? Where did they come from? Why were they scattered in two places? What did the yellow-clad wizard gain from it? Countless questions were like frenzied swarms, buzzing in his mind, giving him a deeper understanding of the mystery of the black stone. Suppressing his surging thoughts, Liu Qian's eyes re-locked on Chai Yi and asked the last key question: "So, how did you steal the ghost grass without knowing it, under the close guard of the dragon spirit guard?" " Chai Yi seemed to have been prepared. She lifted her bound hands and pulled up a worn-out sleeve with difficulty, revealing a snow-white and delicate arm that looked like congealed fat, completely different from the camouflage on her face. Inside her slender wrist, a round ruby with a deep color like clotted blood was tied to her. "Rely on magic, my lord." Chai Yi's voice had a hint of weakness: "This ruby was cast by Yaxia's shadowbinding agent with powerful magic, and I was the one who stimulated its power and briefly transformed into Miss Janice in the form of Miss Janis. " Her eyes quickly glanced at Janice who was sitting next to Liu Qian, "With Miss Janice identity and aura, I was able to hide the perception of those guards, enter the warehouse, and take away a bundle of ghost grass." " Her words explained the weak magic fluctuations that Liu Qian sensed in Valantis, and it was the power of this gem that was taking effect. Liu Qian was stunned, Melisandre had used similar magic in the original work. He continued to ask, "What do you want the ghost grass for? Also to replenish magical power?" " Chai Yi nodded: "The fact that ghost grass has magical power is not a secret in the Far East, and more magic can also make this magic gem last longer..." After Chai Yi finished speaking, he took a deep breath and focused his thoughts. I saw that the ruby on her wrist suddenly lit up with a strange dark red halo, and the light instantly enveloped her whole body, rippling like water waves. The light flashed, as if a layer of clumsy painted skin had faded, and the hideous scars and rough and dull skin on her face disappeared like phantoms. Instead, it was a breathtaking beauty. The skin is better than snow, and it can be broken by blowing. The facial features are as exquisite as the most perfect masterpieces of the gods, with picturesque eyebrows and eyes, a beautiful nose bridge, and natural cherry red lips. The most shocking thing is that her eyes are no longer the ordinary brown color when camouflaged, but like the purest amethyst carved color, in a thrilling contrast with her waterfall-like black hair. At this moment, she is like an elf coming out of an ancient picture, with a thrilling beauty that mixes purity and nobility. This is the true face of Princess Kakosa Chai Yi. Liu Qian's gaze lingered on her unique violet eyes for a moment, with a hint of inquiry. This kind of eye color is extremely rare in the Far East. Chai Yi seemed to be aware of Liu Qian's doubts, and explained softly: "My lord, in the history of the Yellow Dynasty, there was a Son of Heaven who married a dragon king of the Valyrian Freedom Fortress, and since then, there have been occasional descendants with Valyrian characteristics in the direct blood of the Yellow Dynasty. " Liu Qian slowly got up from the main seat, he put his hands behind his back, pacing back and forth in front of the kneeling prisoners, each step seemed to step on the tight heartstrings of Chai Yi and Luo Wen. Only the echo of his footsteps and the crackling of flames were left in the hall, and the atmosphere was extremely depressing. "It's a pity," Liu Qian stopped, his eyes swept over the faces of Chai Yi and the others: "Even if you confess these secrets, I still can't let you go." " The hearts of Chai Yi, Luo Wen and the others suddenly sank into the abyss, and despair shrouded them again. Liu Qian announced coldly: "There are only two ways in front of you, either surrender to me, or die..." "What?!" Luo Wen could no longer suppress his anger and struggled to stand up, but was severely pressed back to the ground by the dragon spirit guard behind him: "The princess has told you the key to the growth of the ghost grass and the shocking secret of the usurper's possession of the Black Stone, isn't this enough in exchange for our freedom? How can you be so treacherous?" " "Treachery?" The corners of Liu Qian's mouth curled up: "When did I promise that as long as you tell the secret, I will let you go? You know too much of my secret, do you think I would be stupid enough to leave such a fatal hidden danger for myself?" " Chai Yi's delicate body trembled violently, and her purple eyes were full of despair and unwillingness. She looked at Luo Wen, who was angry but held down by death, and then looked at the cold man on the high seat. The tragic death of her father, the fall of Kakosa, the hardships of fleeing all the way, and the desperate situation of life and death at this moment... Countless images flashed wildly in her mind. In the end, the bitter hatred that was buried deep in her heart and supported her to this day overwhelmed all the humiliation and unwillingness. Chai Yi's voice had a heartbreaking determination, she stopped the guard's unnecessary impulse, and her purple eyes looked directly at Liu Qian, as if to imprint his figure in the depths of her soul: "I choose to surrender." " "Wise choice." Liu Qian's face did not have the slightest wave, as if this outcome had already been predetermined. He walked down the stone steps and went straight to Chai Yi, who was kneeling in front of him. The girl's beautiful face was still stained with tears, and her purple eyes were intertwined with fear, humiliation and a hint of stubbornness. "Open your mouth." Liu Qian's voice was unquestionable. Chai Yi didn't know why, his body trembled slightly with fear, but he still opened his cherry lips obediently. Liu Qian stretched out his left index finger, his mind moving slightly. A drop of viscous and hot blood containing powerful magic slowly oozed out, and in Chai Yi's terrified gaze, Liu Qian accurately dripped the hot golden dragon blood into Chai Yi's slightly open mouth. The cold and powerful contract power instantly melted into Chai Yi's body as the drop of dragon blood flowed into Chai Yi's body, reaching the core of her soul. Chai Yi was struck by lightning. A scorching torrent that seemed to come from the origin of life instantly swept through her limbs and bones, washing away her consciousness, and she felt as if her soul had been thrown into a furnace and forcibly imprinted on it. On the book of contract ignited by golden flames in the depths of her soul, Chai Yi trembled and signed her real name with her mind. Airplanes! In Liu Qian's mind, the system panel jumped clearly, and the number of Flame Knights became three. "Very good, the magic contract I signed with you is deep in your soul, and from now on, your life, your will, and everything you have will exist only to serve me." His gaze turned to Rowan and other guards, whose faces were ashen, and only despair remained in his eyes: "As for you, for the sake of the safety of the life of Your Highness the princess, I advise you, it is best to also offer your loyalty and serve me, her life is now with me, if I sense a trace of betrayal, the dragon blood contract in her body will make her understand what it means to be truly worse than death." " His words completely shattered the last trace of resistance in the hearts of Luo Wen and the others. Luo Wen and the others seemed to have been stripped of all their backbones, and slowly nodded their heads with unwillingness and numbness of resignation to the bone marrow.
