Billion Dollar Husband, Delivered to Your Door!

Fortunately, I caught the exam in time.

She glared at Yun Wei. In this exam, she must play well, and she will never let Yun Wei take the lead, so that she can avenge her revenge.

Tomorrow night, he gave Yun Wei a cold look and said, "Okay, start the exam."

Yun Wei glanced, and there were ten students including herself, three boys and seven girls. Sure enough, women still have more love for jewelry?

As for what Fang Lisha was here for, she didn't know too well. Anyway, Fang Lisha showed up here for the exam, right?

Ming Ye Leng stood in front of everyone.

He was awe-inspiring, and there was a high coldness on his body, revealing indifference.

He waved, and someone immediately brought two dishes.

These two plates are covered with brocade cloth, and I don't know what is covered underneath.

Everyone didn't know what was going to be tested in this exam, so they couldn't help but look at those two sets of things.

Ming Ye said coldly: "Today's exam content is very simple. There is a plate of glass shards and a plate of broken diamonds. I will mix them together. All you have to do is to distinguish between glass and broken diamonds. Come on."

When everyone heard this, their faces suddenly twitched.

This exam is too simple, right? Those who come here to study, have not all been in contact with jewelry, and who have not come to school with testing equipment?

The molecular structure of glass and diamond are completely different, and it is very convenient to use detection equipment.

If you want to distinguish broken glass and broken diamonds, there is no difficulty at all. You only need to take out the instrument, put the broken glass and broken diamonds in, check it, and you can tell immediately.

Even Fang Lisha, who doesn't understand jewelry at all, understands this truth.

It seems that I have seen everyone’s thoughts, and the corners of the cold lips will cause an upward arc tomorrow: "You cannot use instruments, and you cannot take out the broken diamonds and broken glass. You can only distinguish between them here, using the existing things here. ."

He shrugged and said, "I don't know what's in this conference room, although I can find anything you need, as long as it is in this room."

Suddenly, everyone burst into tears and couldn't use any tools, so how to distinguish them?

Isn't this clear to embarrass people?

If there are tools, it is not difficult for everyone present, the detector is the most convenient and quick tool.

Yun Wei also secretly thought: "If you can't use the detector, the people here must have a way to distinguish broken glass from broken diamonds. It's very simple. You only need to use the heavy liquid separation method. The so-called heavy liquid separation method. It is a method of separating minerals in heavy liquid with a certain density according to the density of minerals. Pour the heavy liquid into the separatory funnel, put the sand sample, and stir repeatedly. The denser minerals sink, and the smaller It floats up. The density of glass is about 2.5 and the density of diamond is about 3.5, which is easy to distinguish."

But Ming Ye Leng said that he can't go out, and can't use everything except here, and the heavy liquid is obviously an industrial chemical substance, and there must be no more here.

Obviously, no one can solve this problem with instruments and heavy liquid separation.

Suddenly, the ten people were a little dumb.

Ming Ye Leng looked at Yun Wei impatiently, and in order to embarrass Yun Wei and drove her out directly, he did not think of a way.
