Su Ziyang's plan was like this: since they've come, they must have committed all their forces, leaving their rear vulnerable. Therefore, seize their retreat path and cut off their chance of returning.
Let the upper realm bring people to Crow Ridge City and start a war with them.
"The key point is how to notify them?" The Master of Xiao Yao Mansion muttered in frustration, as this was the most helpless matter. If someone could be found, without a doubt, they would encircle them, ensuring they could come but not return. It was also feasible to trap them in Crow Ridge City.
"The only way." Su Ziyang looked at the Master of Xiao Yao Mansion and the others, making a gambling decision, "Attack the City Isolation Formation to create a disturbance, drawing the attention of the people from the Four Great Holy Lands. The tremors from the Isolation Formation will surely make them believe something has happened in the city, and they will definitely send someone."
