Later, she told him that using snake venom to treat the rare cold toxin in his body was a case of fighting poison with poison. He asked, "Did your grandfather teach you that?" But she smiled even brighter than the sunlight outside the house. "No, an old lady in my dream told me." "..." At the time, he was speechless after hearing that. Still, ever since she applied this poison-fighting-poison method, his body gradually improved. He no longer underestimated this dark-skinned girl. Playing with her in the mountains, chasing each other, he no longer felt tired. In the past, even a few minutes of running would leave him gasping for breath. He stayed in the mountains for four months, fully recovered, and was taken back by his family. After that, he never returned. Once the cold toxin was expelled, his body remained healthy, and the little girl gradually faded from his memory. Later, when the news of Chu Jinian's family being murdered exploded across nations, he finally remembered that little girl. Learning that she and her family had died in that fire, he felt a deep regret. He believed that if the little girl had lived, her medical skills would have surpassed her grandfather's as she grew up. He never expected that the little girl hadn't died. That little girl, whom everyone called Yaya, was Chu Lingzhi. It was only recently, when he noticed her acupuncture techniques resembled Chu Jinian's, that he secretly investigated her. Step by step, he uncovered that she was Chu Jinian's granddaughter. That little girl who proudly told him that sometimes money can't buy health or life—she was the mother of his son. Meeting her again, knowing she hadn't died, his view of her changed. If it hadn't been for her "fighting poison with poison" treatment back then, his body wouldn't be so strong, able to withstand countless blades and bullets. This woman once gave him health, and now she has given him offspring—her contributions are undeniable. Perhaps this fate was destined long ago. Nangong Yehen curled his lips into a faint smile. When had he ever believed in fate? "Master Chu's medical skills were superb, and he was proficient in the alchemy passed down through generations of his ancestors. If he hadn't been killed, he would have saved countless lives by now." Huo Luan looked at the grassy field and spoke regretfully. Thinking of Chu Lingzhi, he felt a bit of comfort. They all knew that to survive, Chu Lingzhi had hidden her exquisite skills. "Master, you've been standing here for a long time. Why not head down the mountain?" A gust of wind carrying the cries of wild boars blew over, and Huo Luan said with concern. Nangong Yehen turned around, rare for him to show a joyful smile to Huo Luan. "I remember, it was you who brought me here back then." At that time, Huo Luan was seventeen and had already been by Master Nangong's (the male lead's father) side for two years. He was someone Master Nangong had brought back. Now, sixteen years had passed, and Huo Luan remained loyal to them. Huo Luan's eyes flickered with a trace of memory at the words. Time flew so fast; sixteen years had passed in the blink of an eye. But his benefactor was no longer alive. Huo Luan looked at Nangong Yehen. He was his benefactor's son, and he would protect him for the rest of his life. The two descended the mountain, not heading straight back to T City. Instead, on the way, they dialed Mo Chen's phone— ***** Having not seen Nangong Yehen at the estate all day, Chu Lingzhi was restless. Not that she missed him or longed for him. But her left eyelid kept twitching, unsettling her, as if something was about to happen. She didn't know why this was happening. Not seeing him for a day, and she was actually worried about him...
