Tang Shunian thought for a while and then said, "You must make a promise that after I release Jing Yiran, you will never hunt me ever again in my life!"
In the killers' field, a killer's promise was the most effective of all. Since a killer couldn't keep showing up in different places, an oral contract was held valid enough in such cases. As a result, all oral contracts were as effective as a written one, and the majority of killers would not break the promise, otherwise they would not be able to receive any more missions in future.
Tang Shunian did not trust Lu completely, but an oral promise was better than nothing. The more skilled a killer was, the more faithful she might be.
Angel had always had a wonderful reputation in killers' field, and had never broken any promise.
Lu's quick answer last time had made Tang Shunian suspicious. This time, she hesitated for a long time before spilling out one sentence, "If you let him go, I will not kill you."
