Looking at the shocked look of the two of them.

Qin Yu smiled, "I tell you that the clarity of the bronze mirror made by Dayi Kingdom is not as clear as mine, right? Have you ever seen such a clear mirror?"

Xiao Nan walked over in amazement, "Brother-in-law, let alone meet, I never thought that if I hadn't seen you make it with my own eyes, I would have thought you were a treasure borrowed from heaven."

"Tsk..."

Qin Yu glared at Xiao Nan, "How many times have I told you, science! We must believe in science! Don't be like gods or ghosts at all times. We must be atheists, and our destiny is in our own hands!"

"hehe......"

Xiao Nan smiled and nodded quickly, "Brother-in-law is right!"

Qin Yu turned his head to look at Shen Binglan again and asked, "Miss Shen, how about my glass mirror?"

Shen Binglan raised her eyebrows slightly, "It's okay."

Qin Yu raised his eyebrows and looked high-profile, "What's wrong?"

Shen Binglan said indifferently: "The mirror is good, but the person is not good, so it's okay."

This statement is implemented.

Xiao Nan couldn't help laughing and was born, "Hahaha..."

The only one in this world who dares to confront Qin Yu like this is probably Shen Binglan.

"cut!"

Qin Yu waved his hand disdainfully, "I am loved by everyone, and flowers bloom when they are blooming. The great Qin man in the workshop car has a very noble character!"

Shen Binglan looked at him contemptuously.

In her heart, Qin Yu will always be a prodigal son.

Xiao Nan looked at Qin Yu and asked in confusion: "Brother-in-law, what is the principle here? The glass is clearly transparent. If you apply a layer of things, how come it becomes a mirror?"

Qin Yu said seriously, "This involves knowledge of physics."

Xiao Nan was full of doubts, "Physics?"

Qin Yu nodded, "This is called the reflection principle. The reflection ability of the mirror to face light is determined by the angle of the light incident, the smoothness of the mirror and the coating film behind the mirror."

"Is the smoothness of the bronze mirror comparable to our glass? The coating film behind us is the best material for making glass mirrors, so the scenery reflected is very clear."

Xiao Nan listened and suddenly realized, "Ao~ So that's it."

Qin Yu looked at Xiao Nan in surprise, "Do you understand?"

Xiao Nan shook his head, "I don't understand."

Qin Yu: "..."

Shen Binglan was also listening, but she was also confused.

She had never heard of such messy things as physics, emission, light, etc.

Shen Binglan felt that these things either came from the sky or from another world.

Qin Yu waved his hand, "Forget it, forget it, the things involved in it are too profound. You just need to know that glass mirrors are better than bronze mirrors."

Xiao Nan nodded repeatedly, "Brother-in-law is right!"

He originally thought it was a big project, but he didn't expect it to be so simple.

Qin Yu only took one incense stick to create a glass mirror with such high clarity. If Dayi Kingdom knew about it, it would be pissed to death.

It’s really damn it, but it’s time to throw it over and over.
