After flying for 100 miles, they saw a mountain pass.
"This is the entrance that leads to the true fire," Nan Li said.
Xuanyi asked, puzzled, "It's underground?"
"The true fire has to be kept underground to suppress its power. Otherwise, it'll definitely cause a disaster," Lu Zhou said.
"Listening to Pavilion Master Lu's words is better than 10 years of reading," Xuanyi said, filled with praise.
"Huh?" Nan Li looked at Xuanyi in confusion. 'What kind of flattery is this?'
Xuanyi seemed to realize his words were too flattering so he quickly cleared his throat and said solemnly, "Pavilion Master Lu, you're really well-read; I can't compare. Let's move on."
Xuanyi said the words 'let's move on' very casually.
Lu Zhou could not be bothered with these things. He looked at the mountain pass and said, "Lead the way."
Nan Li led the group underground.
