A lot of the people who come to the exhibition come in groups.

While waiting, familiar people talked to each other, and only Yin Rena, who came alone, browsed the "Potions Research Results" here.

Some people also wanted to come to Yin Rena to talk to her, but whether it was her appearance or temperament, it discouraged ordinary citizens like her.

Say it is the princess of the empire, and they will also kneel down and shout "Long live the princess!" without doubt! ”

Although no one has ever seen what the princess looks like, compared to the woman in front of her, it should be almost the same, right?

If there is anyone more beautiful than her in the world, it is estimated that the only one who lives in the myth is the "God of Flowers and Beauty".

But Yin Rena didn't bother to pay attention to them, and took care of herself to "admire" Reno's works.

Through close observation, Yin Rena could see several potions with obvious characteristics.

The blue agent with a blue flocculent precipitate is estimated to be copper hydroxide.

This stuff is covered in chemistry textbooks in junior high school.

This Reno has actually made it?

But this world doesn't even have the most basic concepts!

Thinking of this, Yin Leina's heart suddenly had a thought:

If he doesn't intervene and sets Reno to succeed in the future, does that mean that this man will be the originator of chemistry in this different world?

It is like Boyle who wrote "The Skeptic Chemist" or Mendeleev who pioneered the periodic table?

If this is the case, then Mr. Reno's status in Yin Leina's mind has been greatly improved, and it is conservatively estimated that he is also a six-star operator in scientific research.

Yin Rena can't help but look forward to this exhibition.

When the time came to 9 o'clock in the morning, the exhibition officially began.

Reno, dressed in a black suit, came out of the ear chamber and coughed twice, all eyes on him and stopped talking.

He stood on a podium slightly above the ground, with a microphone with amplification in front of him.

"First of all, welcome to my 'Potions' exhibition, my name is Reno, and next, I will explain to you the latest potions I have made these days!"

As he spoke, his assistant brought a test tube containing a colorless, transparent, viscous oily liquid.

Reno took the test tube, carefully pinched it in his hand and held it high: "The most different thing about this exhibition from the past is that it! ”

"A potion that really works!"

"When I made it by chance, I discovered that it has extremely powerful corrosive abilities, and its corrosion degree is no less than that of an extraordinary potion!"

"And does it produce energy?" Hearing the words no less than the transcendent elixir, some people in the market who yearn for the transcendent and want to make money from this gimmick can't help but move some crooked brains.

But Reno shook his head honestly, "It's a pity that I can't replicate the conditions at that time, and I'm not sure that I can make the same potion, so this potion, the only one in the world!" Does anyone want to buy it? We can auction! ”

But there was silence in the audience, and no one wanted to be this wronged boss at all.

After buying this thing, what is the use of other than the Yin Man?

Everyone present is a normal person, how can you use a yin person?

Reno on the stage was really embarrassed and quickly took out the next "magic potion".

And the next solution is not as shocking as the first one.

There were many solutions that even he didn't know were of any use, and they could be put on display simply because they had a special color.

Only he himself knew that these solutions were formed by mixing with other solutions, and not dyed with pigments.

But those viewers didn't know that their first reaction was to dye it with paint, and they suddenly lost interest.

The voices of doubt grew so much that Reno could barely hold himself up.

In a hurry, he directly came up with the finale.

"Ladies and gentlemen, there is a finale of this exhibition, please follow my steps."

The crowd made way for him, looking at him like a clown, to see what else he was going to make.

No one was optimistic about him, except Yin Leina.

In this world, I'm afraid she is the only one who understands how much Reno has done.

In the next finale, she is also looking forward to it.

couldn't help pursing his lips, but in Reno's eyes, the girl he was very concerned about actually laughed.

Is she looking down on me?

Damn it!

I'm going to make them all look at me!

With reluctance, Reno came to the "demo table" that could be seen at the entrance.

Quicklime is obtained after limestone is fired with fire, quicklime is added to water to react to produce mature lime solution, and caustic soda is added to lime aqueous solution for chemical reaction, and the generated calcium carbonate will sink to the bottom, and the remaining solution is lye.

Then mix the lye with the most readily available lard, heat it, and stir it.

Continue to saponify over low heat, stirring and stirring constantly......

The water was steaming, but the time had already passed in the stirring for half an hour, and who knows how long it would take, and the citizens didn't have the spare time to waste so much time here, pretending to look at their pocket watches and then follow their friends or partners, pat their butts and leave.

With the first person to leave, the others followed suit, and they weren't interested in it anyway.

In this way, there were fewer and fewer people on the scene, and Reno's hand holding the fast stirring became more and more stiff and unnatural.

In the end, Yin Rena was the only one left on the scene.

As at the beginning, he always sat on the side, pursed his lips and smiled as he watched his experiments.

Everyone left the venue, including his assistant.

Reno even received his resignation letter when the assistant left.

Reno's exhibition can be said to be a complete failure.

When only Yin Rena and Reno were left on the scene, Reno finally chose to give up, and the stirring hand was about to be put down decadently, at this moment......

"Don't stop, keep going, it's your last spectator's request."

"As a person who runs an exhibition, there is only one person left, shouldn't you just go on?"

Reno turned his head and glanced at Yin Rena in surprise.

Although he was moved, his heart was already cold, and he continued to stir the solution mechanically as if he had completed his task.

When most of the water had evaporated over time, Reno placed the rest of the liquid on the table and set himself aside.

It means that the result is here, I'm going to roll up the cover, clean up and get out, you please.

One last glance at the product that he had been stirring hard for an hour, Reno turned his back, and even his back was bent by the weight at this moment.

But he hadn't gone far, where was the experimental table, and suddenly there was a nice voice, like a heavenly sound:

"Sodium bicarbonate and grease will undergo saponification reaction in a heated environment to form 'soap', which has a powerful cleaning ability, Mr. Reno, you are only one step away from success, are you willing to give up?"

He turned around in disbelief, only to see that the graceful and noble lady had taken the beaker herself and poured the liquid into the prepared but useless cuboid mold.

"Let's wait two more hours, and then, I think, the first bar of soap in this world, will form a ...... in your hands"
