"How is this possible? You've planted spies on our side!" Ying An was somewhat overwhelmed. If the opponent's mere use of spies had caused flaws in Qin Country's plan, he absolutely wouldn't want to concede.
If a general were to lose honorably on the battlefield, then it's a defeat, and one should accept it willingly! But if the opponent used intrigue and trickery, Ying An wouldn't be convinced!
However, he saw Luff shake his head, denying his view: "No, no! We didn't get intelligence from spies at all."
"Even if we did, it's only a part." Luff extended his finger, praised Qin Country a bit: "I must say, your counter-espionage work was quite effective, it indeed affected the efficiency of our intelligence personnel."
