Yin Kuo seemed to know what Su Tang was worried about, so he added.
"How about this, help me with a favor within your ability range, and rest assured, you can definitely do it and I won't ask you to do anything bad. What do you say?"
Su Tang didn't speak, her eyebrows tightly furrowed, almost forming the character for 'river'.
"I thought that your life would be far more important than a promise," Yin Kuo said with a smile, but the smile never reached his eyes.
Su Tang took a deep look at Yin Kuo and after several seconds of silence, she spoke, "I promise you, but in addition to the conditions you just mentioned, you must also promise me that once my tribespeople find us, you won't use this as a reason to ask them for favors."
Yin Kuo nodded, "I can do that."
Su Tang saw how readily he agreed and couldn't help but feel suspicious for a moment.
