The next morning, Jiang Yu got up and rushed to check the condition of the potted plant.
The succulent plant, which had a strong vitality, had already withered.
"Withered?" Jiang Yu was shocked.
How could it have withered in just one night?!
Jiang Yu quickly removed the glass cover, and a pungent smell mixed with the fragrance entered Jiang Yu's nose.
"This smell is..." Jiang Yu searched quickly in her mind and finally identified a gas. "Sulfur dioxide?"
Sulfur dioxide itself was a colorless gas with a pungent smell. If inhaled in large quantities, it would cause harm to people's heart, brain, and blood vessels. In severe cases, it could even lead to cancer.
Kang Zheng must have diluted the sulfur dioxide gas, placed the gifts inside to absorb the gas, and then sprayed some perfume to cover up the pungent smell.
