In a huge "Colosseum" -

On the face of the black boy Eugene, the relaxed energy that was originally bright and playful was completely gone, and beads of sweat the size of his beans came out one by one......

And the small-eyed middle-aged European, unhurriedly, on his badly damaged test bench, with an evil smile on the corner of his mouth, carefully mixed with those chemical reagents. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Eugene looked at this European nervously, he had already poured out the cup of special sulfuric acid very hard just now, no matter what he said, it should be able to spill on the other party's head, it was impossible to take a step or two back and dodge!

"It seems that that gibberish brother, he has already made a colorless resistance gas just by using those few tubes of solution!" Tang Sen said with emotion, he had to admire the middle-aged European......

"You see that, too?" Liu Yin was very surprised, she didn't expect Tang Sen to be really a master! Even some of the little actions of that European were all visible to him!

"It's not simple, look at the little eyes of Brother Messy, don't think he's slow, in fact, the speed on his fingers is already operating as fast as magic!" Townsend stretched out his palm, shaking his fingers rhythmically in front of him, but he couldn't reach that speed.

Liu Yin stretched out her slender jade hand again, and after sliding a few more times like a snake between Tang Sen's palms, a piece of chewing gum appeared in Tang Sen's hand inexplicably.

Tang Sen's eyes widened very widely, and his chin was very exaggerated, he didn't expect that Liuyin's sister would also do magic, you must know that magic is generally used by men to pick up girls.

And now Liuyin's sister behaves like this to him, does it mean something else? Could it be that she is hinting at something? ……

Liuyin saw Tang Sen's admiring and slightly colored eyes, and she didn't know whether to dislike it or pretend not to see it, so she quickly turned her head helplessly and continued to look at the two contestants who were making new chemical reagents......

"Where did you learn this? Hand speed is so fast! Tang Sen asked in astonishment, he had thought that Liuyin relied on his mind and used the high-tech products designed by Mai Qi to attack and defend.

But through the moment of lightning just now, Tang Sen was completely impressed, because he felt ...... It's so cool to do magic!

Liuyin didn't pay attention to him, because this unserious living treasure was no longer off topic once or twice, as long as he talked to him seriously, he would be taken to the ditch......

Tang Sen realized that he was a little bored with himself, so he muttered to himself: "It's really stingy, what are you hiding so deeply?" They are all assistants, so why bother with assistants!? ”

Liu Yin pursed her lips and held back a smile, ready to explain a little to Tang Sen, but she found from her afterglow that Tang Sen was actually pouting angrily, looking towards the competition area with his arms folded, and complaining from time to time.

Seeing that Tang Sen could still self-regulate, Liuyin felt that there was no need to comfort him, so she relaxed and leaned back in her chair, watching the match she had already predicted.

For another short period of time, the black boy Eugene, he changed his previous strategy, and through these chemical reagents, it seemed that it was not so simple to directly hurt his opponent, because he also realized that the opponent had already quietly defended.

And it can defend so quietly and so well, and even before consuming a few tubes of solution, it can already make such a powerful colorless gas barrier!

It seems that the small-eyed middle-aged European knows the ideas of the black boy Eugene well, and this young man, although he is particularly proficient in chemical reagents and the speed of practical operation is far beyond ordinary people, but he can't figure out the other party's intentions.

"Looks like this game is a bit mysterious." Townsend said nervously, because as he watched Eugene look for a new way to attack the small-eyed middle-aged European, even he knew what Eugene was going to do next.

"Actually, it's a game without suspense." Mai Qi spit out a sentence indifferently, her words were always as bland and tasteless as boiled water, but they seemed to have revealed everything......

"Why? I think that black lad has a good chance of winning the game! You're talking about this guy being able to kill the big bad guy in seconds, right!? Townessen's description of the small-eyed, middle-aged European was already eager to curse him to death with words......

Mai Qi just smiled slightly, looked very elegantly towards the competition area, and signaled that the answer was inside.

Tang Sen couldn't get an answer, so he had to watch quietly, his hands rubbing back and forth on his thighs excitedly, and he bared his teeth with a look of eagerness.

After discovering that the use of liquid attacks was ineffective, the black boy Eugene used his clever brain, quickly changed his thinking and routines, and he decided to attack in a solid way!

When he had precipitated solid crystals through various wonderful chemical reactions, he carefully processed the crystals of several colors with tweezers......

Eugene frowned, his expression looked as if he was not satisfied with these crystals, was there something missing in the operation process? Or is the result not ideal? The audience had no way of knowing.

He took out a small freezing device from under the lab bench, and then used tweezers to cool the solution of dark green crystals to below zero degrees Celsius and introduce hydrogen chloride gas, precipitating purple crystals.

Eugene then treated the solution of purple crystals with a special reagent, and precipitated a light green crystal with hydrogen chloride gas, and finally a smug smile finally bloomed on his face that had been tense.

And his opponent is still operating slowly, and he still looks at Eugene from time to time, and it seems that he is dual-minded, and it is difficult to think that this guy can have the possibility of winning the game.

"Crystal hydrate!?" Townsend was surprised again, isn't the level of these contestants a little too powerful? This idea is really bold and crazy!

"What do you see again?" Liu Yin didn't forget to test Tang Sen and make it difficult for this new assistant.

"Crystalline hydrate is pure, because each molecule carries the same number of water molecules, the composition of the molecule is fixed, and the molecule has a strong interaction with water!" Tang Sen said to Liuyin as he wrote the chemical formula in the air with his fingers.

"And what's the use of him doing that?" Although Liuyin probably guessed the idea of the black boy Eugene, she felt that a normal person would not choose to do that - this way there was a risk of doom!

"Like bile alum, it seems to be a mixture from the chemical formula, but it is not simply a mixture, but there is a strong interaction between the two of the mixture! This guy named Eugene is not going to be ready to ......" Townsend gasped.

He was very surprised, because don't underestimate the light green crystals that were precipitated, this was the last bargaining chip for the black boy Eugene to give it a go, and the odds were extremely high! (To be continued.) )
