Niu Ping's grandfather put away the bone needle and let out a long breath. Although the formation wasn't very complicated, it still took him nearly three hours to pierce through the entire formation. When he was done, he looked at Niu ping and found that he had fallen asleep.
Niu Ping's grandfather couldn't help but chuckle. This wasn't niu Ping's fault. The Niu clan had rough skin and thick flesh. This kind of tattoo was really nothing to them, so it was normal for him to fall asleep.
Niu Ping's grandfather didn't get angry. He took out some clean water and washed off the formation he had drawn on Niu Ping's body. Then, he carefully looked at the formation on Niu Ping's body and finally nodded. There was nothing wrong with the formation. It was perfect.
