章節 1172: The treatment of an internationally renowned expert

Department Director Kong was a little worried, and he stared at the screen.

It was not difficult for Zheng Ren at all to make a few large bends when the guide wire was used to super - select the position.

Now, Department Director Kong was already used to Zheng Ren's "extraordinary" performance, and he turned a blind eye to it. He focused on the black shadow that represented the spring ring as it entered the blood vessel along the guide wire.

That's not right. This black shadow doesn't look like the spring ring I'm familiar with.

It was very thin and small.

The more precise the consumables, the more difficult it was to operate, but this was definitely not a problem for boss Zheng. The question in Department Director Kong's mind was what a Huahua was.

A nerve coil? It seemed to be smaller and thinner than that one.
