Lu Cheng's suggestion wasn't too unreasonable.
Based on one premise, that is, Tian Zhuang hadn't bought the link Lu Cheng sent yet.
Even if Lu Cheng was promoting it, without completing the transaction, he couldn't profit.
Besides, Lu Cheng was indeed the duty doctor, and the shift at the emergency department wasn't a joke.
In contrast, today Tian Zhuang and his brothers seemed to treat the "emergency department" as a joke, stirring up trouble over such a minor issue.
It's clear to anyone with a discerning eye that Lu Cheng suggested Tian Zhuang buy the operation tools to teach him the technique—it's a tool for learning, just like pens and notebooks for elementary students.
If you don't want to buy or learn, then don't, but it's odd to escalate it to the school and claim the teacher suggested you buy a pen and notebook, intending to trick the teacher.
The reason sounds ridiculous, and such ridiculous reasoning must have other motives behind it.
