The deputy generals came to a realization and cupped their hands to apologize for their previous disrespect. Rong Yan did not mind. Just as he was about to go with them, he heard someone say, "We can't have no generals in front of the formation. Leave such a lowly person to us."
They were all experienced in front of the array, so it was not a problem for them to follow and hide. Rong Yan knew that he was a newbie in this matter, so he did not interfere and really stayed behind.
The deputy generals chose two people and followed the spy at a safe distance with 500 elite soldiers. The rest stayed behind and guarded against foreign enemies with Rong Yan.
