Sable initially thought of Long Tao's plan to be unbeatable. But the talk just now made him realize a new perspective of looking at the situation. The whole plan was built straight upon the choice Nightshade would be making. Just as Long Tao said, If he chose to attack the princess with all their forces, he included, she would be dead by now. The choice of the division was the condition that led to the downfall of the assassins.
"Look at it from a different perspective. What if they would have attacked tomorrow instead of today? The situation would be totally unpredictable as well. Another pillar leading to our success is that they chose to attack today itself." Sable didn't speak out this time. He took his time understanding the situation and looking at it from more critical angles. Although Long Tao's plan was ingenious, he had prepared for just one of the outcomes. Anything deviating from that would have been a probability game.
