Huang Yuyi’s Nirvana, The Fire Boy and Huang Yuyi, The Auction In Heavenly Ancient Merchant Planet

Ye Zhu suggested everyone gather at the Heavenly Ancient Merchant Planet, and Chu Kuangren did not reject that idea. 

The crowd happily went to the planet.

Not long after Chu Kuangren and others left, a group of golden-red Phoenix's Flame suddenly emerged in the void. A Godly Phoenix was reborn in the countless interweaving Daoist patterns, with its tyrannical and domineering aura spreading everywhere.

Some sky-prides that had not left were astonished by such a scene.

"A Godly Phoenix bathed in flames? It's Nirvana!"

"Who is it?"

"Who else could it be? It must be Huang Yuyi whom Chu Kuangren killed. I didn't expect her to go through Nirvana. She's so lucky."

Godly Phoenixes did not go through Nirvana successfully every time, and the chances of succeeding were tiny. 

Besides one's aptitude and talent as a Prodigy, one must possess a great deal of luck to trigger the Godly Phoenix's Nirvana.
