Yao was completely stunned. If he had to describe it, it would be two words: Awesome.
Li Wu has completely entered that mysterious state. No external objects can affect him, and all noises have nothing to do with him. He only focuses on the work at hand.
His movements are very slow, but every measurement is almost one-time to the point and one-time pass.
If you observe carefully, you can find that his movements have a very obvious sense of rhythm, when to move and when to be still, with a clear time interval, just like a robot.
As the best special soldier, no matter how well-known Yao graduated from a bachelor's degree, he graduated with the rank of lieutenant, but he couldn't describe this phenomenon. He thought hard for a long time, but couldn't find a reasonable explanation. He tried to learn Li Wu's rhythm, but was quickly defeated.
