Chen Yun's question hit the nail on the head.
If nothing is detected, then there's a problem with the formula.
Li Lei said in a deep voice, "If that's the case, both you and Zhang Yang are responsible. Of course, you could place all the blame on Zhang Yang since he provided the formula."
"I won't!" Chen Yun said resolutely.
Zhang Yang said, "I'm confident that my formula doesn't have any issues."
Just as he was speaking, a woman suddenly rushed over, "Chen Yun, I finally found you. You're the one who ruined my face like this!"
The woman grabbed Chen Yun's hair as soon as she came up, catching Zhang Yang off guard with the sudden change.
But he quickly reacted, gripping the woman's hand firmly.
"Ouch!"
The woman was shocked and released her grip.
Zhang Yang angrily threw the woman aside, "Aunt Yun, are you alright?"
"I'm fine," Chen Yun said with some bitterness.
Then she stood up and looked at the woman. She was an old customer, and they usually had a good relationship.
