Fang Zhengzhi was extremely curious about the Cloud Pattern. He would not miss out on an opportunity to examine it.
He could have joined Princess Shan Yu and beat up the six guards.
But that would have been too disrespectful towards Princess Shan Yu.
After all, if she couldn't even take care of a few guards herself, how could she still maintain her standing in the army?
Of course, there was another reason why he didn't attack.
He would much prefer to sneak in whilst the battle was ongoing.
By doing so, he thought that it would give them a better chance of victory.
He was effectively killing three birds with one stone. He would be increasing their odds of victory, showing respect to Princess Shan Yu, and would be able to examine the Cloud Pattern.
Princess Shan Yu hollered.
