It just so happened that Yi Zheng wanted to ask what the Groundhog King was up to, so he came down the mountain.
He happened to see Zi Gong and the Groundhog King's conversation, and his eyes lit up instantly. There's no better time than now, especially since he had a legitimate reason!
So Yi Zheng gave Zi Gong an OK gesture, meaning go ahead, fight, and give it to them.
Zi Gong understood, patted the Groundhog King's shoulder, and said, "Groundhog King, we're brothers. You said to give it to them, so let's give it to them. I'll lead the way."
"Good brother!" The Groundhog King was thrilled, turned back and shouted, "Line up, grab each other's tails, front row hold hands, don't drop anyone!"
Then the Groundhog Sect started to line up, holding hands in a row, with the ones at the back biting onto the tails of those in the front, wobbling into the air towards Changliu Mountain.
Yi Zheng watched their method of operation and thought, "Why haven't I noticed such talents before!"
