After hearing Nie Yuan's doubts, Cang Lang dismissed scornfully, "How would this be fake? Within the Demon Alliance, only Elder Ancestor Bai could stand a chance against me. However, his heart lies with combining his forces with humans, entirely forgetting his duty as a demon. He has really forgotten where his root and ancestors lie! I must eliminate this calamity from the demons, lest the demons perish and be defeated even though we were not actually beaten!"
Then, his voice took a softer turn after he saw Nie Yuan's affected state. "As long as you can help me get rid of that fellow, the Demon Alliance would then be led by me. When that happens, gifting you a mere Greater Rat Clan as an award for your assistance will just be a trivial matter."
How could this still be a trivial matter?
Nie Yuan clearly knew the current state and potential of the Greater Rat Clan. After all, he was once part of them.
