Internet celebrities forcibly exchanged tickets, and my identity as a boss was exposed!

The microscope room is not far from here, walk forward to the intersection, and the distance is less than 300m after a turn.

Chu Chen walked over there, took only two steps, then turned back to Ji Junguo and said, "Don't use this ladder any more. You can do the work that can be done below first, and let go of the work above for now."

He really didn't expect that he just stayed in the library for a few days, and the students didn't even dare to report to the finance department to buy a ladder.

He thought a little defensively: These students are still too kind, and I should protect them well.

Well, after working with Chu Chen for two days, Chu Chen already regarded them as half students in his heart.

But Ji Junguo, who was still standing in the same place behind, was a little dumbfounded. If the work below had not been completed, who would climb the ladder to find the work above?
But after all, this was Chu Chen's caring heart, Ji Junguo nodded in agreement, so that Chu Chen could feel at ease.

I smiled wryly in my heart: It seems that my work is done today.

Chu Chen naturally didn't know these thoughts in Ji Junguo's mind. Seeing Ji Junguo nod honestly, he continued to walk towards the microscope room with satisfaction.

It's like Ji Junguo who was working just now.

When Chu Chen came to the microscope room, none of the three people working hard looked up at him.

Everyone was silent in their own world, and no one noticed his arrival at all.

Seeing such an appearance of working hard and earnestly, Chu Chen didn't say anything, but secretly nodded in his heart: "The students taught by Master Song Ming are hardworking."

It seems that not only talent, but also hard work is equally important.

Isn't there a saying that talent determines your upper limit, but hard work determines your lower limit?

However, some people often can't hold on to it before they have reached the point of striving for talent.

Chu Chen himself is a hardworking person, so he naturally likes people with the same qualities.

I think that when I am working hard, I don't pay attention to the surrounding environment at all, and I don't want people or things around me to disturb me.

Chu Chen judges others by himself, thinking that they also don't like being disturbed by others.

Just like before, Chu Chen didn't make a sound, standing behind them, silently watching their skilled manipulator microscope to observe.

Each of them had a thick book spread out in their hands, and they flipped through it from time to time, and there was a notebook on the other side.

After watching for a while, Chu Chen felt that it would be better to work together by himself, otherwise it would be boring to stand here.

There are a total of five microscopes in this microscope room. Except for the three of them and Chu Chen, there is no one in the microscope room.

In other words, there are two spare microscopes.

Sitting down next to Ma Wei, Chu Chen felt that Ma Wei was his own beside him. He thought that some colleague came to use the microscope, and he didn't even glance in this direction from the corner of his eye.

Naturally, he didn't realize that it was Chu Chen who came.

Sitting next to Ma Wei, Chu Chen clearly saw a book in his hand.

The book was as thick as a brick, the pages were slightly yellowed, and the footer was frayed. It seemed that it had been used for a long time.

Because the book was spread out, the cover of the book was pressed underneath, and Chu Chen didn't see what the name of the book was.

But from the contents of the page he opened, Chu Chen knew that this was a book introducing mineral pigments.

Although Chu Chen wanted to help with the work, he couldn't do it without samples.

Chu Chen had no choice but to call out Ma Wei's name softly, and said, "Ma Wei, do you have any extra samples? Give me one."

Ma Wei didn't realize that it was Chu Chen who came, and thought it was Song Chaochao or Li Jiale asking him for specimens.

Without raising his head, he said, "Save the sample, didn't I just give it to you?"

Song Chaochao and Li Jiale also thought that Ma Wei would talk about them again, they raised their heads in bewilderment, and said to Ma Wei in a daze, "We didn't ask you for samples."

Chu Chen laughed out loud, "I'm the one who asked you for samples."

Hearing the familiar voice, the three of them suddenly turned their heads to Chu Chen.

Ma Wei said in shock: "It's you, you have come out of the library."

What Chu Chen said was even more funny, and the tone was so funny that he changed the words to: It's you, you have already come out of prison, it's not an exaggeration at all.

Chu Chen suddenly laughed even more heartily, making Ma Wei and the others confused, and he didn't know what was funny about what he said.

Wiping away the tears from laughing, Chu Chen said, "The three of you seem to read different books?"

The difference between the three books is quite big, and Chu Chen noticed it at a glance.All three books are not the same.

Ma Wei nodded, pointed to the book in front of him and said, "My book is about pigments extracted from minerals."

Then he pointed to Song Chaochao and Li Jiale in turn: "Song Chaochao's book is about pigments extracted from insects, and Li Jiale's book is about pigments extracted from plants."

"We first roughly divided the pigments into these three categories, and then checked them one by one against the books."

Hearing Ma Wei said that there were also pigments extracted from bugs, Chu Chen raised his eyebrows with interest, walked to Song Chaochao, and picked up the book in front of his face.

This book is the thinnest among the three. It turns out that it is about the pigments extracted from plant bugs, no wonder there are so few of them.

Compared with extracting pigments from minerals and plants, there are indeed fewer types of bugs.

It is not uncommon for insects to extract pigments. Chu Chen knew that many insects could extract pigments.

For example, the most common cochineal is the most important raw material in ancient lipsticks. In modern cosmetics, cochineal is also widely used in high-priced brand-name lipsticks.

Why there is no cochineal in low-priced lipsticks is because the price of cochineals is very high, and lipsticks cannot be used at all.

There is also Shougong sand ordered by ancient women, which is to feed gecko with cinnabar. When the gecko is red all over, it is dried, crushed, mixed with a special solvent, and placed on the woman's arm.

Compared with the cochineal worm, the cinnabar gecko is not a pigment according to the gecko’s Shougong sand, because the pigment in its body mainly comes from cinnabar, not produced by itself.

The cochineal is actually a pigment that it produces itself.

While flipping through the book in his hand, Chu Chen asked casually, "Since you took out this book for comparison, have you found the paint extracted from the worms in the mural?"

I thought that Ma Wei and the others would give him a positive answer, but unexpectedly, they all shook their heads.
