If I had mastered the Spiritual Array back when I was in Zhao Family's Ancestral Hall, I would have been able to lay a trap formation outside the hall. Even when facing that green-skinned evil ghost, I wouldn't have ended up as miserable as I did.
Having thought of this, I immediately put my thoughts into action.
I took the public bus and visited the small commodity market again, looking for old book stalls.
A book called "Qimen Dunjia" attracted Xiao Mu's attention.
Holding the book in his hand, he asked the stall owner, "How much is this book, boss?"
"Three hundred."
The boss gestured with three fingers.
I didn't expect that the price of books had risen again in just a few days.
Xiao Mu didn't haggle over the price and directly paid for the "Qimen Dunjia", took it and headed home.
I started to modify "Qimen Dunjia" and two options popped up.
1. Body Method.
2. Array Method.
