This was the last trial for anyone that was going to become an immortal. It was the trial of the mind. If one had no firm mind or strong willpower, the laws of nature would not accept this warrior.
When a warrior could not see through the fake and the truth or was without a heart to rise to the challenges, the warrior would be doomed even the warrior could become an immortal.
The two keywords were origin and truth. Lu Li could not have become an immortal without understanding these two words. Now, the conditions were ripe, and success had come.
"Boom, boom, boom, boom~"
The thunder clapped. Xuan Qi in the entire Prison of Wind was gathering around Lu Li. Lightning glared in the sky but did not strike at Lu Li.
Lu Li looked up with pride. He noticed the lightning had five different colors. He understood that those were from the Prison of Thunder.
