The Chu generals and commanders waited for the assassin's signal to proceed with their ambush, however, even after a few hours had passed since the leader of the assassins sent his order for them to cause mayhem inside the city, there was still no news to be heard.

This only made the Chu soldiers stand on pins and needles. 

And just when they thought that the Zheng empire found out about them and executed them, a reply was received. 

One soldier was riding a stallion and passed through the barricades and soldiers guarding their camps. No one obstructed him aside from a casual glance and question, but the soldier who was questioned took out his Chu army medallion from the first commander. 

Everyone soon recognized that lone soldier as one of the ten assassins planted inside the city and let him go. No one questioned him about what happened as he looked like he was in a hurry.
