Yin-Yang Harmony Array
Zhang Fei let out a heavy sigh as he put on a disappointed face. "Senior, I know my protective array is very weak, but it's still better than nothing, right? Our family is only a small one, so we don't have enough money to buy the best ones. Anyway, I got it from my friend, so I want to use it for the time being until I have enough money."
"Don't you have a master who can create a stronger protective array?"
"Unfortunately, I don't have a master in formation arrays, and I learned them by myself." Zhang Fei's answer caused Fa Zhen to raise his eyebrows in disbelief. "Honestly, I have been studying them for a long time, but I have never created a single one of them due to difficulty finding their materials."
Fa Zhen suddenly pulled out a paper that contained the method for creating a simple formation array and handed it to Zhang Fei. "Learn it first, and I will get the materials needed to create it in the back."
