"There are no sharp objects like needles piercing through," said Gu Yunze as he examined, "If there's no wound on the surface, it might be poisoning by inhalation."
Gu Yunze had often dealt with enemy spies infiltrating Great Xi while confronting adversaries at the border.

Gu Yunze had seen too many incidents like this where the war horses were tampered with, so he was experienced with many methods.
"If it's poisoning by inhalation, we'll need a coroner to inspect," Gu Yunze said.
"Leave it to me." Xiao Chengyu said, "Keep a close watch on everyone from the stables; no one is allowed to leave."
"Investigate who they met before, and watch who they contact afterward today," Xiao Chengyu said.
"Yes," Jing Lai quickly responded.
"I have some people on my side who can help with the investigation as well," Gu Yunze said.
Xiao Chengyu did not refuse because the Gu family surely had their own network and methods in this area.
