"Makes sense." Zhou Yugui nodded.
"I found that this person not only concealed their entire body, but also scattered odor-removing powder to eliminate their body scent. It showed that they were extremely cautious. Also, look here."
Xia Houji led Zhou Yugui to a window Wei He had stepped on when leaving.
He pointed at a small patch of damage left on the window.
"This should be where the assailant borrowed force to escape. Look—the damage to this window lattice should have been left when a boot stepped forward, pushed off, and used the force to leap away."
Zhou Yugui went over for a look. Sure enough, upon close inspection, he could make out the direction of the damage. Only the method Xia Houji described, and the direction of the force, could have caused it.
Xia Houji continued, "In other words, the murderer sprang into the air and left from here. Quite a few guests saw the direction in which he departed.
Combined with the movement technique he displayed when attacking Young Master Yan, it was clear that his Leg Skill was not weak.
So the most urgent matter now is to find out whether, when the attack occurred, there were any traces in this stretch of woodland of him borrowing force to leap after leaving from here.
If there are none, then we look at who was lingering in that direction on the main road at that time. Investigate them one by one along this line, and our efficiency will be much greater."
"But wouldn't that still require investigating many people?" Zhou Yugui frowned.
There were so many people coming and going along this road. How were they supposed to investigate? How could they know who had stopped in that direction during that time?
"Not that many, actually." Xia Houji
