Zheng Ren watched in amazement as fan Tianshui stabbed the young waiter with a straw.

Although the straw is a little hard, it is absolutely not sharp. Sometimes it can't pierce the soft paper package on the beverage.

Can bend, habit will not pierce the tough skin, Zheng Ren is a little puzzled.

What I said was to stab the skin with a knife and then insert the hose. Who let fan Tianshui stab directly.

But when the idea just appeared, Zheng Ren heard a "hissing" sound from the straw in less than one second.

This is the sound of huge high-pressure gas in the chest after it has an outflow tract.

"Is that ok? President Zheng?" Fan Tianshui was confused and honest.

He asked in a low voice for fear that he had done wrong.

"..." Zheng Ren looked at the gas spewing out of the straw silently and felt that all this was too mysterious.

Su Yun came out with a sharp knife in his hand. The boss hasn't figured out the situation yet. Seeing him with a knife, his face turned white at once.

This is when you meet a freeloader and carry a knife to intimidate yourself?

Even if you eat free food, you are still so arrogant!

But he is just a businessman who has opened a chain store and does some small business to support his family. How dare he face the sharp knife.

Subconsciously, he hid behind and tried to disappear in Su Yun's eyes.

"I'll go..." Su Yun rushed out and saw a straw inserted in the midline of the patient's left chest lock. The newspaper can do it, and so can the straw. But we are medical literature, treating the sick and saving people, so let's treat tension pneumothorax.

Well, I'll report to you as above.
