Chongbai Yu put his hands behind his back and carefully observed the disciples of Tianlingling who had come to take the exam. www.biquge.info Although Wang Qi has always behaved casually and leisurely, it is impossible for him not to care about his empirical department. And even if Chong Baiyu is dissatisfied with Wang Qi, he is doing his best to do this work.

At least, he knew that only when Wang Qi's Empirical Department was operating normally could he leave here and return to Huo Tongqing's Alloy Refining Empirical Department. Therefore, even if it is for himself and his own future, he needs to do a good job in this recruitment, and then let this empirical department run well.

And at this stage, all the Burning Gold Valley disciples were doing the same thing - melting the ice. The water he provided was only a few hundred catties, and with the solid gallium chloride, he could just make up 800 catties of detection medium. If the hand slip evaporates a few catties of water, it is basically impossible to pass the assessment.

Gallium chloride is very easy to hydrolyze, and when dissolved in water, it will release a large amount of heat. Gallium chloride itself is highly volatile. If the water is heated too high at this level, it is easy to volatilize the gallium chloride, resulting in the final solution of less than 800 catties.

At this level, most of the Heavenly Spirit Ridge disciples were very serious.

Chong Bai Yu, on the other hand, was carefully observing the disciples of the Burning Gold Valley who were doing empirical evidence.

The interviews arranged by Chong Bai Yu are inclined to experimental operations. This is also Wang Qi's request. However, what Wang Qi wanted was the kind of experimentalist who could control the collider—the kind of person that would be almost impossible to have during the Dan period. Even he Chongbai Yu hadn't seen a collider a few times, and those research projects that could understand colliders in the Dan period were considered good.

Therefore, after thinking about it, all he can choose is "character", "attitude" and "ordinary experimental level".

Configuring the detection medium is something that usually doesn't need to be done by the monk himself. In China, there is a uniform detection medium produced by the Taisha plant in units of "10,000 tons", and then transported in units of "1,000 tons". It is not uncommon for a colliding weapon of Wang Qi's scale to use a few hundred tons at a time. If it's the bigger ones, it's for thousands of tons or thousands of tons.

And after a batch of media has been detected several times, it has to be replaced by another batch

This is usually done in "months".

In other words, no matter how biased it is, it is very simple to order the detection medium and let Xianmeng deliver it once a month. It's not something that people do.

In other words, the questions he prepared were in essence too harsh, as if he was forced to test the skills of a secretary or accountant in making paper from pulp and paper, and from animal hair.

However, people who can still be meticulous in this situation are obviously more calm. In Wang Qi's rather avant-garde and anti-common sense empirical department, this kind of person is even more sluggish.

Chong Bai Yu patrolled the examination room, and also examined the expressions of the test takers.

As he expected, most of the Heavenly Spirit Ridge disciples were very disapproving, and the movements on their hands also looked very unsightly. These people must not be left behind. And of the small group of people who remain, only a few are doing it happily. These need to be carefully observed, depending on whether they really think that "doing empirical evidence is really fun" or are really stupid, not knowing that this is not a human job.

And when Chong Bai Yu was observing those people, those applicants were also observing him.

Yan Xiancheng is one of them.

Yan Xiancheng cleanly dissolved the eight-hundred-pound hilt with real fire. At the same time, he carefully wrapped all the ice cubes with mana, ensuring that not a trace of water vapor would reach into it. And his mana shuttles back to the ice cube, increasing the internal energy of the ice cube as a whole. I didn't see how the ice melted, but I saw it become wet. Then, the whole block of ice splits apart, turns into smaller fragments, and melts in one piece.

Rather than using real fire to melt the ice, this will control the melting process and reduce the evaporation and loss of water.

Then, when the water temperature is about four degrees, the supplied solid gallium chloride is shredded and dispensed in batches. In this process, he had to reverse the previous operation and continue to extract heat, so that the temperature of the solution was maintained at less than 30 degrees.

After that, it's time to stir up the mana and stir it evenly.

For the mana of the monks in the Dan period, the mana lifting of only 800 catties of objects is also idle, and the subsequent operations are not particularly complicated except for temperature control. Yan Xiancheng was used to doing these things. Fifteen minutes is a tight time, but there is still room for veterans. So, he looked up again and looked at each other.

"The topic is not too strict, I think most of the Burning Gold Valley's knots can be completed. In this case, you want to sift out five or six hundred people, leaving only ten?"

"What the hell is the standard?"

Thinking of this, Yan Xiancheng was always a little uncomfortable in his heart. This practice also shows that the criteria for admission of the other party are not calculated based on the progress or results of the empirical evidence, but on the performance in the empirical process.

What is performance? It's not a matter of the examiner's words?

For the exacting true seeker, this subjective standard is bound to be unpleasant.

The solution gradually clears. This means that it is already even. After the gallium chloride solution stabilized, he took out the six non water and cold iron, and used his thoughts to manipulate the mana restraint solution, while his hands were sealed to assist in refining the talisman seal. Soon, a simple rune array was completed.

But when it came time to make the second solution, he hesitated.

He could see that the remaining four solvents were organic solvents, benzene, ethers and ammonia.

The trap is definitely in there.

"Gallium metal is the main group of elements...... In the case of the main group elements, the valence electron configuration of the atom is ...... The outermost electron ......"

"GaC...... To be precise, gallium trichloride, a covalent compound, where the valency of gallium metal is ......"

That is, gallium chloride...... It is possible that it is very easy to form ammonia complexes with ammonia......"

In other words, if the solvent of the second solution is ammonia, it is finished.

"It's still a little too easy, though. ”

If it's a trap, it's a little too simple. The general Burning Gold Valley should be avoidable. Even if you don't know how to confirm it, you have to try each solvent first......

No, the quality of the solvent is fixed, and if one part of the solvent is added to one part of gallium chloride, the quality is just 800 catties. If you try it randomly, you may also be eliminated because of a few grams of defects.

And the disciples of Tianlingling here only have the Dan Formation Period, and they can't do the separation of matter at the atomic level. If you want to react and then change back without loss, it will definitely not work. And with so few reagents on hand, it is difficult to reduce.

If you are too reckless, or too careful, you shouldn't be able to do it?

"It seems that the other party mainly looks at the performance. ”

Yan Xiancheng calmed down, took a solvent, and began to make the second "eight hundred catties".

For this highly volatile organic solvent, the temperature must be well controlled. The temperature is too high, and the solvent volatilizes to say, but if it is all gone or the reaction is lost, then the exam will be passed.

A quarter of an hour passed quickly.

"Alright, junior brothers and sisters, stop the Dharma in your hands. Chong Bai Yu's voice spread throughout the examination room. Then, everybody really stopped.

No monk in the Yudan period dared to cheat under the spiritual consciousness of a monk in the Yuan Shen period.

Then, he checked from the first one.

"Well, it's a classic thermostatic array, and the setting is also very reasonable. He nodded, wrote something in his shorthand notebook, and then said, "Senior Brother Jin Qiwu, right? Go back and wait for the news." ”

The named monk nodded excitedly and quickly walked out. But instead of going far, he politely stood outside the gate.

"Well, it's not bad, although the rune path is a bit ......"

"Ah, this is my family heirloom...... The ancestors themselves tinkered with it, and there are some differences from the popular talismans of the Immortal League, but I have been used to it since I was a child. Seeing that Chong Bai Yu had some questions, the monk immediately explained.

Chong Bai Yu was noncommittal, and said, "Senior Brother Ye Shuheng, go back and wait for news." ”

For everyone, he just glanced at each other, and then made a short comment or two, without wasting any time.

When he was about the tenth, his hand lightly touched the solution sphere, and then said, "Senior Brother Junren, I'm sorry, I'm not qualified." ”

This examinee's name is quite Confucian, and his temperament is also upright, and he said, "Please Mr. Chong tell me why I am not qualified." ”

"When you melted the ice, the real fire was used a little more violently, and it evaporated by three catties, am I right?" Chong Bai Yu seemed to have expected it, and said, "You used the cold ice on this ground to fill the vacancy. ”

Jun Renjie's face was a little unhappy: "This is 10,000 meters below, and the ice is already very pure......

"First of all, the solid ice I provide, which is essentially ultrapure water, has a complete removal of the conductive medium, complete elimination of organic matter, and all the dissolved gases are discharged. Chong Bai Yu waved his hand, revealing a mischievous smile: "Secondly, on the ground here, I sprinkled a little bit of table salt, and all of it was slapped into it with mana. If you look closely at the conductivity of these ice cubes, or if you look at the crystals on its surface, you can see it. ”

Jun Renjie's face turned red, and he walked out without looking back.

"I know that many of you are troublesome, or think too much about the topic and think that the topic must have a deep meaning, or are afraid that there are traps in the organic solvents, so you are clever enough to dig up ice cubes from all sides to make two points of aqueous solution, or use ice cubes to make up for the part of your own volatilization. ”

"If you're careful enough to spot sodium chloride crystals mixed in with the ice crystals - don't stare at me, this is something you can do during the Dan Formation - or strong enough to turn these ordinary ice cubes into ultrapure water, I'll pass the test. However, if not, then sorry. ”

"Although our empirical department is a small place, and the boss is a layman, we don't welcome those who are opportunistic and lack the necessary skills—after all, what kind of research do people who can't do it carefully?" (To be continued.) )
