Shi Nian stood in front of him at close range, looked through Cao Jian's somewhat cloudy eyes, and did not find a weak and flustered look, and felt a slight pause in his heart, was it really not him who did it?

On second thought, maybe he was a battle-hardened old fritter, and this accident might not be anything in his eyes. Thinking of this, Shi Nian reminded himself not to take it lightly.

"It's not Boss Cao's decision on this matter, to tell you the truth, I'm a student of Zhixing High School, but at the same time, I'm also Fan Ronghua's granddaughter, you shouldn't be unfamiliar with this name!" Shi Nian always hooked the corners of her mouth, no matter whether Cao Jian was loud or quiet, she had never been suppressed in momentum.

"Fan Ronghua?, is it really your restaurant that has an accident?!" Of course Cao Jian knows this name, her purchase volume has increased exponentially in the past few months, and she is one of his big customers.

And Fan Ronghua is kind-hearted, whether it is a businessman or a student, she is usually kind and temperamental, and she doesn't like to care, so her popularity has always been good, and Cao Jian is also happy to cooperate with her.

"That's right, my grandmother was hospitalized because of this, and now this matter is taken over by me, and if I don't find out, I'm afraid that similar things will happen in the future. Boss Cao, the management and health department of our school have already found out the results on the same day, and the toxic substance is poisonous mushrooms, which is the batch you sent over that day!" Shi Nian bluntly put the results of the investigation on Cao Jian's face.

"Poisonous mushrooms?!" Cao Jian asked in shock. He only inquired about the food poisoning accident at Fan Ronghua's meal, but he really didn't inquire about what caused it.

Before the matter is properly dealt with, the relevant departments of the school are in the stage of news closure, which is also to prevent the order of the school from rioting.

School leaders must stand at the height of the overall situation, looking at the overall situation to make decisions, at this time if everyone is aware of the trouble, I am afraid that it will cause riots, especially those parents of students living in the hospital, I am afraid that it will be more difficult to appease, and it will also make the public lose confidence in the school.

"That's right, looking at Boss Cao's appearance, it seems that this is the first time you know?" Shi Nian looked at the shock in Cao Jian's eyes, and his heart was slightly relieved, and he couldn't help asking.

Cao Jian's heart was a little heavy, although he had already checked the remaining ingredients as soon as he knew about the poisoning incident, but when he saw Shi Nian's sworn appearance, his heart was still a little drumming.

"The things I have here are all purchased from regular channels, no matter who comes to inspect them, there will be no problems! As for the poisonous mushrooms you mentioned, that's even more nonsense!" Cao Jian said with an angry expression.

"Boss Cao, are you so sure?" Shi Nian stared at him tentatively.

"Isn't my own stuff clear to me?!" Cao Jian gritted his gums and said word by word.

"Okay, since you said so, then I still have a question to ask Boss Cao, were the mushrooms that day freshly delivered in the early morning, or the inventory of the previous day?" Shi Nian looked at the look on his face as if he was fake, and turned his head to ask a seemingly irrelevant question.

Cao Jian lowered his eyes and thought for a moment, and then replied: "What I sent you that day was the previous inventory, but there is absolutely no problem in terms of freshness or safety and hygiene!"

"Then apart from you, is there anyone else who has interfered with the storage of those mushrooms, or has anyone else touched those mushrooms?" Shi Nian knew that the direction of his investigation was about to change.
