"Yes, this is it," Yun Nian said, not minding the strong smell but rather her eyes gleaming with excitement. "This thing is even more valuable than gold."
Du Jin was puzzled. "Princess says this stinky sticky liquid is valuable?" He covered his nose, unable to see its worth.
"What stinky? This is fire oil, pure fire oil, you know," Yun Nian clarified. It was unexploited fire oil, worth a fortune!
Although the Western Mountains appeared desolate, there were actually oil fields underground.
Emperor Hong Wen must have learned about it in advance and had people ambush the Western Suburb Camp.
They dug out the fire oil and silently formed a circle of encirclement using the fire oil, trapping the Western Suburb Camp.
"Has all the fire oil around the camp been cleared?" Yun Nian casually asked without even lifting her head.
