Night Leaning Moon could have used the Vast Sea Wave-Raising Flute to exchange for many Creation Master resources from the Moon Empress, Chef Supreme, and the Bamboo Monarch.
She was being so generous to Lin Yuan because she saw him as her disciple.
It was similar to how the Moon Empress had been willing to give the 200 insect-species carcinoma feys she won from the bet to Liu Jie.
Liu Jie nodded and said, "Master, I will give this precious instrument to Lin Yuan once I return!"
Night Leaning Moon could clearly tell that Liu Jie's smile had become even more radiant after he received the Vast Sea Wave-Raising Flute. Evidently, he was happier about obtaining a 5 Stars precious instrument for Lin Yuan than he was about obtaining one for himself.
After Liu Jie left the Spirit Guards' land, he instructed the Insect Queen to produce three of the Lonely Night Hurricane Moths to carry him to the Return from Faraway Mansion.
