Zheng Qing ultimately couldn't direct the large mountain goat to seek help.
Perhaps it was because his 'Sheep Man Language' was not yet advanced, so the big mountain goat couldn't understand what he was saying; perhaps the goat was merely refusing to accept such a garbled command—it was very unmagical to ask an animal companion to stray from its unconscious master.
In any case, after three minutes of Zheng Qing's dry-tongued bleating, the big mountain goat remained stationary before him, chewed on what could've been its late-night snack, and looked without expression at the young wizard's performance.
This made him feel rather foolish.
At the four-minute mark, the big mountain goat was no longer a spectator—perhaps simply because it had grown tired of the young wizard's strange calls—it solved Zheng Qing's problem in another way.
It awakened Lin Guo.
