Ling Hua was preoccupied with inquiring about the results of Ling Yunyang's research into the "Book of Prophecies," and when Ling Yunshen invited Cui Yanshu to a game of chess, she signaled Ling Yunyang to speak with her in his study.
Ling Yunyang understood, as he also had something he wanted to discuss privately with Ling Hua, so the two of them went to his study together.
Upon entering the study and closing the door behind them, Ling Yunyang didn't wait for Ling Hua to ask and directly said to her, "I tried it out and managed to deduce a little something, but it was only a little, and this little bit nearly cost me my life."
Ling Hua frowned, "What do you mean?"
"It made me vomit a great deal of blood, and my head hurt so much it felt like it was going to explode, my heart as if it were being pricked by needles. I ran to Marquis Duanjing's residence to see Doctor Zeng, and after he took my pulse, he scolded me severely. He asked if I wanted to die."
