Fight

After some thinking, Feng Yun decided to make a sneak attack and reduce the number of enemies first. He continued to wait as he watched them bombarding the formation. He was elated when he saw the ten assassins were heavily injured by the formation. 

Feng Yun was more than happy to wait and watch them suffer under the formation. As long as the formation was standing, he decided to wait and let them exhaust their spirit energy first.

However, when he saw the leader throwing the explosive talisman, he knew that he couldn't hide anymore, so he took the initiative to attack.

Hiding in the black pagoda, he easily came to the assassins without being detected by them. While their attention was fully occupied by the formation, Feng Yun sneaked up behind an assassin thanks to the black pagoda and killed him in one strike. He thought he could take out two or three assassins, but their reaction was fast. Well, they were all sovereign profound realm cultivators after all.
