At night, something odd was discovered in the Jibei Army's military camp.
After eating dinner and drinking water, most men found themselves unable to lift their hands and feet, their bodies limp and slack, even unable to hold a knife.
A Military Doctor was summoned, who immediately diagnosed, "It seems like food poisoning."
"What kind of poison?" Zhang Cheng was shocked.
"It appears to be the Soft Tendons Powder." The military doctor had some skill indeed.
Zhang Cheng's face changed as he looked around. Most of the men were lying on the ground, too weak to move, he asked, "How did they get poisoned?"
The Military Doctor also did not know.
"Investigate it immediately." Zhang Cheng ordered.
The Military Doctor examined more than ten individuals, confirming, "General, they're all the same. It's the Soft Tendons Powder."
He was puzzled as to who could have silently poisoned them within the Jibei Army's camp.
"Is the Soft Tendons Powder fatal?" Zhang Cheng inquired.
