Seeing this information, Huo Sining suddenly remembered the uneven watermark on that piece of paper. She was absolutely certain that the "Buzhou Mountain" must use the legendary Hidden Mist technique that required water to reveal the true face of the painting.
However, the possibility that the paper was coated with lime was dismissed by Huo Sining. Lime is highly corrosive; it produces intense heat and emits a pungent smell when it comes into contact with water.
Yet the painting in front of her showed no signs of damage, and she did not detect any particular odors, so this explanation did not hold up.
The mist dispersed quickly, and once the water had disappeared, the painting returned to its original state, with no discernible change in the inked mountains.
All three people in the room found the situation unbelievable. It was their first time witnessing ink turning into mist when it came into contact with water.
