Even though Su Chengyu agreed, Su Haoyu was still uneasy, and he demanded: "Swear an oath, a venomous one. No matter what Chenglin does, you won't kill him—you'll spare his life. Otherwise, you will meet a horrible end."
"It's not necessary!" At last, Gong Juechen spoke, though the three words, loud and sharp as they were, carried a choking, tearful tone.
Su Chengyu hadn't expected Su Haoyu to ask him to swear such a venomous oath. He was momentarily stunned, but without paying heed to Gong Juechen's objections, he truly swore the oath—just to put his father's mind at ease: "With the gods as my witness, I, Su Chengyu, solemnly swear here today that no matter what my seventh brother does, I will spare his life. Should I break this oath, may I die a terrible death."
Even though Gong Juechen knew Su Chengyu took the oath to calm Su Haoyu, his heart was nonetheless deeply shaken.
