Zhao Bowen immediately got furious.
He dashed to the eighth floor at a speed comparable to Liu Xiang running 110 meters hurdles, burst through the door and yelled: "It's done! It's done!"
"What's done?" Bai Zhen asked.
"What's done?" Wang Ning asked.
"We've passed the toughest hurdle! Applaud! Applaud!" Zhao Bowen was visibly thrilled, while Bai and Wang clapped somewhat confusedly without understanding why, as Zhao happily hummed a tune and continued to draw circles on the map of Nanjing City with a compass and a pencil.
