Hui Feng Zi was startled and furious.
Even though he did not surrender willingly, because of the situation, after he had surrendered to them, he could only work for them even if he did not want to.
Central Continent ordered him to stay here and guard Luo Po valley, they had naturally made many arrangements on his body.
Hui Feng Zi was restricted by them, and for the sake of his safety, he had to stand up and stop Fang Yuan from taking Luo Po valley.
But when he saw Fang Yuan, Hui Feng Zi, who was startled and furious, shook intensely, he called out in fear: "Feng Jiu Ge!"
Fang Yuan looked at him lightly with a calm expression.
The Central Continent Gu Immortals had already left Northern Plains and returned to Central Continent. Then, they would naturally leave some arrangements back in Northern Plains. How could the astute Fang Yuan not guess this?
Thus, while taking Luo Po valley, he turned into Feng Jiu Ge.
