It was the precious tears of immortals!
Song Shuhang had encountered similar treasures before, so he was very sensitive to the sudden drops of sorrowful tears from the Almighty Merchant... At that moment, he wished nothing more than to immediately open the coffin and collect the precious tears of immortals.
Even a single tear of immortal sorrow, if not processed in any way, could simply be thrown at an enemy, forcing those below the immortal realm into a state of 'sadness', crying uncontrollably. It was just like the effect of the "Tome of Never-Ending Tears".
Unfortunately, no matter how quick Song Shuhang's reaction was, it was futile... The flying sword coffin had already been sealed shut. Even if he forcibly broke out of the coffin, he wouldn't be able to catch the tears of sorrow from the Almighty Merchant.
