Sikong Yan paused for a moment, then burst into wild laughter: "I have to say, you're just as crafty as that old fellow. That's right, it's about erasing memory."
As his laughter subsided, he lowered his voice and said, "Because by doing this, if he ever finds himself in a bind, and others don't get the secret formula, at least he can find a way to survive."
"After all, if someone else got the secret formula, they'd likely do the same as the old fellow did to his alchemy brother, kill them to silence them and keep the formula to themselves."
Hearing this, Zhou Qing gained a deeper understanding of the Old Emperor's shrewdness.
"Then how did you manage to see the secret formula back then?" Zhou Qing pressed on.
Sikong Yan only chuckled slyly, a hint of craftiness flashing in his eyes: "Some secrets cannot be revealed."
