章 266: Chapter 224 Heaven Does Not Seal Off All Exits

Mist hurried to Song Heping's side.

"Check this out."

Song Heping pointed upward.

Following his gaze, Mist saw a ventilation fan, about 60 centimeters in diameter.

"A ventilation shaft?!"

Mist's eyes lit up.

"Did you plan this all along?"

"Not really," Song Heping said. "When I came in, I thought there had to be a ventilation system. Otherwise, wouldn't people suffocate in such a big cave?"

"You're willing to bet on that?" Mist said. "Unless you have the blueprints for this place, how can you be sure it leads out?"

"I really don't know."

Song Heping moved closer to the wall and looked up.

Through the rotating blades, he could faintly see that there was space above.

A 0.6-meter-diameter tunnel might just allow an adult to squeeze through.

He turned to size up Mist.

Mist wasn't one of those particularly tall and stout Caucasians; he should be able to crawl through.

And Rabbani, even less to worry about.

There weren't many overweight people in Afghanistan.
