Li Yundong worked hard and didn't earn asters. He immediately smiled bitterly: "Hey, don't mess around. If you can't cut it well, I have to shave my head! I haven't shaved my head since I was young!"

Ziyuan didn't answer directly, but with a click of the scissors in his hand, he cut off a piece of black hair. Li Yundong immediately shivered in his heart: Well, cut first and then play! Forget it, bear it, as long as you don't shave a mossy head or a mangy head!

Ziyuan cut a few knives and found that Li Yundong looked brave and fearless. Her eyes were more tragic than the * * * Children's shoes of the devil's guillotine. She couldn't help laughing: "don't worry, I brought up Hongling from childhood. I cut her hair. Do you think I'll cut her hair?"

Li Yundong was relieved when he heard this. He smiled and said, "that's good. I thought you used my head as a test field!"

Ziyuan chuckled, "with your hair like a chicken nest, you still have a test field? I think it's at most a wild grass!"

Li Yundong said with a smile: "whether it's the experimental field or the wild grassland, anyway, don't mess around and cut it flat for me!"

Aster smiled faintly: "no, don't worry."

"Well, I'm at ease when you do business!" although Li Yundong responded well, he secretly said in his heart: you have a criminal record first, but I'm not at all at ease!

Ziyuan had dexterous hands and fast scissors. Li Yundong just felt that she was busy nearby. The scissors clicked, and his hair fell one by one. He couldn't help saying, "Alas, it's only two months. Why is it so long?"

Ziyuan said, "isn't there an answer in the Yellow Emperor's Internal Classic?"

Li Yundong moved in his heart and patted his forehead: "I see. My blood is too strong, right? If my blood is strong, my hair will be strong, so my beard and hair grow so fast."

Ziyuan nodded slightly: "practice is not only to practice magic with luck. You must understand the operation law of these magic, but also the theory and scientific truth of practice."

Li Yundong couldn't help laughing and said, "the scientific truth of practice? Hey, if I used to scoff at this sentence, but now think about it, I really think there is a bit of scientific truth in practice."

Ziyuan said faintly, "what is really a bit of scientific truth? I ask you, what is the law of computer operation? Why can a few chips and circuit boards transmit so many things and calculate such huge numbers? Why does the computer respond when you click the mouse? What is the scientific truth?"

Li Yundong was tongue tied: "how do I know that?"

Ziyuan asked, "do you know how the atomic bomb was caused? What is the scientific truth?"

Li Yundong said with a wry smile, "I'm a liberal arts student. How can I understand these things?"
