Originally, Bei Chengling wanted to add more formations to supplement the current defence.
However, after discovering that the enemy had a formation master, he immediately changed his mind.
'I can only use a different method.' He thought and removed a wooden box from his storage ring.
He opened the box and revealed a set of bamboo slips.
"Young master, are you going to use the bamboo slips?" A subordinate asked.
His tone was subdued and he looked at Bei Chengling in concern.
"The other side has a formation master. It's only a matter of time before the protective formation is broken." Bei Chengling answered.
In the Cangxing world, there were two types of formation methods.
The first method relied on materials to arrange and manipulate formations.
When these kinds of formations were damaged, they could only be repaired by replacing the formation materials.
