No, she thought the PE teacher was the one with the problem.

Why are you crying?

Hearing the familiar voice, Lin Ziyan turned around and saw Lu Yunshen standing at the door with a bag in his hand, and breathed a sigh of relief.

He strode inside, picked up the other child from the stroller, and

Why is Jiaojiao crying?

"My little goldfish is dead... Waaah..." Jiaojiao kept sniffling, her eyes red.

Lin Ziyan felt a chill run down her spine and broke out in a cold sweat.

If Jiaojiao drinks this "sweet soup"...

She shivered and dared not think any further.

The damage caused by high-concentration sulfuric acid is irreversible; the entire oral cavity can be corroded, and the throat may even be completely corroded...

"What's wrong?" Lu Yun Shen gripped her hand tightly; his fingertips were icy cold, his face was pale, and he was trembling.

Lin Atai looked at the bottle in her hand and her first thought was that it was poison.

"High-concentration sulfuric acid is highly corrosive; the goldfish died because its mouth was corroded..." Lin Ziyan held the bottle tightly, not daring to use force.

Lu Yun Shen pulled the bottle from her hand, a cold glint in his eyes.

Jiaojiao understood and turned to look at her second sister, "Isn't it sweet soup?"

Xiaoxiao pursed her lips tightly, her face even paler than Lin Ziyan's.

Highly corrosive?

She had seen this word in a book her sister bought.

She had just looked at the goldfish's mouth; even its head was corroded. Her sister had only given it a tiny bit of the medicine...

“Let’s go out for a bit.” Lu Yunshen gripped Lin Ziyan’s hand and strode out of the courtyard.

The village has a laboratory; a simple test will tell us whether it is high-concentration sulfuric acid.
