Several months ago, before he had resigned from the elevator company, Lin Yun would receive calls from various unfamiliar numbers every week.
Most of them were clients or collaborative enterprises discussing business, so even if the parties were initially unknown to each other, these unfamiliar numbers would subsequently be added to Lin Yun's contact list for easier communication next time.
However, there was always one number without a note in Lin Yun's contact list.
This number had even become a dead line, but he kept it in his contact list just in case he couldn't find it when necessary.
It was the same number that, five months earlier, on the night Lin Xiaolu was in danger, had informed Lin Yun of the location of the attack.
Lin Yun had never forgotten about this incident; in fact, he had actively investigated the true identity behind this number, but to no avail. In the end, he could only save it in his contact list.
