Sure, here is the translation:
"It must be man-made."
Little Situ laughed and said:
"Smile flowers prefer shady, damp places, often found in marshes and deserted lands.
"A single flower or two won't cause much harm to humans.
"However, if it's a sea of flowers and you recklessly step into it, illusions will be endless, leading to death with a smile, hence its name.
"Thus, according to their nature, these flowers shouldn't appear in this forest.
"Besides, it's already late autumn now.
"Leaves have turned yellow and fallen, these flowers bloom in spring and summer, by autumn they have withered and seeded, their power difficult to manifest. They must break through the soil in autumn, grow stems in winter, and wait for the warmth of spring next year to bloom.
"So... smelling the scent of smile flowers here now can only mean that someone left the flower poison intentionally."
After these words were spoken, the Sihai Dragon Heads were greatly impressed.
