Chương 271: Chapter 207 Nine-Star Food Ingredient! The Secret Realm Trial Begins!

Upon hearing this question, Zheng Cheng was moved.

As expected.

Could this be the real intention of the Zheng family?

The source of their special ingredients.

However, Zheng Cheng had already prepared for this and said, "I obtained them from a certain secret realm."

"Oh? Which secret realm?"

Upon hearing Zheng Cheng's words, Zheng Yuanhao's eyes brightened immediately.

"The Morea Mine secret realm."

Zheng Cheng explained, "In the deepest part of the Morea Mine, there's an underground river. Inside the river, there's a species called the Black Sludge Fishman and they've tamed several underwater creatures."

"One of those creatures is the Black Sludge Crocodile, and my special ingredient came from it."

"The Black Sludge Crocodile? I see!"

Zheng Yuanhao's eyes gleamed, "Thank you Mr. Zheng. This is our Zheng Family's diamond black card. With it, you can enjoy a 10% discount at all our family's shops."
