"Um."

Ning Fan nodded. "It's said to be the key that can open the road to the upper city."

"Uptown and downtown, I don't quite understand this."

Feng Wujiang said calmly: "I only know that we used to walk between the two sides without much trouble."

"Before, Chong Wujie said that this was an ancient battlefield. So what exactly is this ancient battlefield used for?"

As Ning Fan spoke, he also looked at the most magnificent coffin.

He first made it clear that the source of this information was Chong Wujie, so as to avoid being accidentally injured when Feng Wujiang mentioned the ancient battlefield again.

"A battlefield is definitely for war."

Feng Wujiang curled his lips and said, "The war back then was much more fierce than the one you're fighting right now. It was going on all the time, day and night."

Ning Fan understood the significance of the ancient battlefield.

only……

"Did you have so many exotic beasts back then?"

The conversation between the two can be considered quite risky.

They all avoid discussing the core issues and just chat about the side issues.

"In the era I experienced, there were no exotic beasts at first."

Feng Wujiang gradually became serious.

Ning Fan was surprised.

Feng Wujiang narrowed his eyes and said, "If there weren't such things, this place wouldn't have become what you call the Lower City."

"Brother, what do you mean by that?"

Ning Fan reacted quickly: "How on earth did this strange beast appear?"

"What do you think?"

Feng Wujiang sneered: "Do you think this kind of thing is naturally produced?"

Ning Fan was stunned.

Feng Wujiang added another sentence.

"Their meat is difficult to make regular food."

"Their fighting instinct is strong."

"There is always a desire for aggression in their minds."

"Don't you think they...are born for fighting?"
