Serena Sterling had to send Zane Crawford away. First, because Zane indeed needed to recuperate, and secondly, she didn’t want him entangled in her matters anymore, or she would really be unable to repay him. Zane and she were not just friends; they were confidants. Zane understood her, so he accepted all arrangements and left. He didn’t ask anything because he understood everything. After sending Zane away, Serena turned to look at Felix Knight. She curled her red lips, "Next, of course, I have to think for myself. I’m scared of dying, and I don’t want to die, so please, Young Master Knight, hand over the antidote for this poison that ages beauty in a snap." Serena came up to Felix, directly spreading out her slender, fair hand, demanding the antidote from him. Felix shook his head, "I have no antidote, Serena Sterling. There is no antidote for this poison that ages beauty in a snap." "Fine, then please hand over the formula for this poison, Young Master Knight. I’ll concoct the antidote myself." Serena arched her delicate, willow leaf eyebrows. This time, Felix revealed an amused smile, "Serena Sterling, do you think I would give you the formula? Don’t waste your efforts. It’s absolutely impossible to get the formula from me; you might find ways, but I have no weaknesses. You can’t threaten me." Felix was right; he was a man without weaknesses. Because of love, there are weaknesses and vulnerabilities, like Serena. To save Zane, she got hit by this poison, which became her fatal weakness. Felix was just an extreme and sick person; he had no love in his heart, only fun. Now the game had reached its climax. He had spent years developing a poison to counter the immortal blood, and he intended to enjoy the fruits of his labor. How could he possibly give up the recipe? Old Man Knight stood by Felix’s side, snorting coldly, "Serena Sterling, stop dreaming. Felix won’t give up the recipe." Original content can be found at novel⚑fire.net "Exactly, Serena Sterling. Not every good thing in the world can fall into your lap. Since you saved Zane, you should die!" Aurora spat venomously. Serena’s emotions didn’t fluctuate because she wasn’t surprised. She had studied Felix’s flawed personality thoroughly and knew exactly what kind of person he was. Serena withdrew her small hand and curiously asked, "Felix, do you really have nothing you care about, no weaknesses? Then what about your grandfather, Old Man Knight, and your sister, Aurora? What do they count as?" Old Man Knight and Aurora had been gloating and arrogant just now, waiting for Serena’s death, but now Serena’s questions froze them instantly. Their eyes landed on Felix’s handsome face. Felix’s eyes flickered, revealing a hint of cold sharpness, "Serena Sterling, what do you mean?" Serena folded her small hands behind her back, "Actually, it’s nothing. I know Young Master Knight doesn’t care about anything, but Young Master Knight indeed has things he possesses. Now I’m going to ruin what you have, leaving you truly with nothing." Felix pressed his thin lips together; he couldn’t figure out what trick Serena was playing. At this moment, there was a sudden gasp, and Old Man Knight moaned in pain, clutching his heart as he collapsed onto the carpet. Old Man Knight had a sudden mishap. Aurora’s pupils shrank, and she quickly rushed over, "Grandfather, what’s wrong?" Felix immediately squatted down to check Old Man Knight’s pulse; Old Man Knight... was poisoned! Felix looked up at Serena, "Serena Sterling, was this your doing?" "That’s right, dealing with a man in his own way. At the wedding, I poisoned Old Man Knight. This poison differs from the one on Zane; Zane’s was a binding poison for control, while Old Man Knight’s poison causes insect-like gnawing pain, unbearable agony." "There’s no need for me to explain the poison to Young Master Knight, right? Poor Old Man Knight, at such an old age, he still has to endure such torment. Who knows how long he can hold on?" "Young Master Knight, now Old Man Knight is my bargaining chip. We can negotiate a deal. How about this - I help expel Old Man Knight’s poison, and you hand over the formula to me, okay?" Old Man Knight didn’t want to give the formula to Serena Sterling. He wanted to speak, but a piercing pain came from his heart, as if something was gnawing at his flesh and blood. The pain turned his old face ghostly pale, making him collapse on the floor, curling up in pain. "Grandfather! Grandfather!" Aurora was scared out of her wits. For many years, Old Man Knight had been the pillar of the Knight family, and with that pillar crumbling, she felt her world had collapsed. "Serena Sterling, how dare you poison my grandfather? You have a heart as malicious as snakes and scorpions!" Aurora turned and shouted at Serena. Serena almost laughed, uncertain of who the real malicious ones were. If she hadn’t been prepared, how could she continue playing around with the Knight family? "Aurora, you’ve been a pampered princess since childhood. Now that Old Man Knight has fallen, you must be very anxious. With Old Man Knight down, the entire Knight family will fall. You might lose everything, unable to even fend for yourself. If I were you, I wouldn’t waste time cursing and instead seriously plead with your dear brother to quickly hand over the recipe to save Grandfather, to save the entire Knight family!" Serena kindly reminded. Aurora stiffened, quickly looking to Felix, holding onto his coat’s edge, "Brother, quickly give the formula to Serena Sterling. It’s just a recipe; Serena Sterling might not even succeed in making the antidote. If you couldn’t make it, how could she possibly succeed?" "Grandfather is our real grandfather. Our parents died when we were young; it’s Grandfather who raised us. Grandfather loves you most, poured his life’s effort into nurturing you. Look at how much pain Grandfather is in. Hurry and save him, hurry!" Felix slowly let go of Old Man Knight’s hand, standing up. His blue eyes were filled with a dark and moist essence, terrifying people. He looked down at Old Man Knight, "Grandfather, didn’t you always want Seraphina Linden’s daughter dead? I’m helping you realize your long-cherished wish. Don’t worry; you won’t be lonely on the road to the afterlife, as Serena Sterling will soon join you. Don’t blame me." Aurora looked at Felix at this moment, feeling a chill down her spine, a shiver to her core, "Bro... Brother, you..." Abandoned, Old Man Knight curled up on the ground in pain, his old face covered in cold sweat. He slowly reached out to Felix, "Fel... Felix..." Serena looked at Old Man Knight on the ground, "Old Man Knight, take a good look. This is the good grandson you raised, a lunatic, a monster."
