Jiang Yining looked up at Lu Zhi's side profile, and her heart skipped a beat.
Lu Zhi focused on the road ahead and was on high alert, ready to face any unknown danger.
The two of them walked along the secret passage for a while.
They found that the end of the secret passage was covered with a sticky blue liquid.
Lu Zhi used his phone's LED light to illuminate the area. After inspecting it, he frowned slightly.
Jiang Yining also picked up some and smelled it. There was a faint stench. "What is this?"
Such a complicated password and mechanism was actually just to protect the liquid?
Just as Jiang Yining was feeling puzzled, Lu Zhi's voice came low and firm, "Curium."
"Huh?"
"This is Curium ore." Lu Zhi said with deep and intense eyes, "One milliliter of Curium can be sold for 800 dollars. And there's an inexhaustible Curium ore here!"
