"If I tell you my secret, can you really let me go?" Li Tian asked with some uncertainty.
"Of course, I'm already so old, why would I lie to a junior like you?"
The green-robed old man said. He looked relaxed on the surface, but he was actually a little guarded in his heart, afraid that the Great Demon King would play tricks.
"Then ... If I tell you my great secret, will you let me go immediately?" Li Tian said carefully, trying to save his own life.
Hearing this huge secret, the green-robed elder's eyes lit up. He had long heard of the Great Demon King's deeds and felt that the Great Demon King was able to advance from Qi disciple Level 1 to the peak of Qi disciple Level 5 at an extremely fast speed. Moreover, his Foundation was stable, so he definitely had the help of some "divine weapon."
