Chapter seventy-five, your t**t. Perfect score

Unfortunately, where they know, the answer is not Lu ran, he just used this half an hour to seriously study basic knowledge.

As for the person who answered the question, Hehe, he also couldn't say who she really was.

The two teachers looked at the answer sheet for a long time and shook their heads. Shake head not because where the answer is wrong, on the contrary, is all the answer is right, some even a little too much, so that they really can not find where "discretionary" explanation, deliberately biased.

As he thought about it, Zheng slipped his finger into one of the answers to question two, making it quite obvious that it was a place they could use as an excuse to point out flaws or mistakes.

But the two teachers shook their heads. That answer was not so much incomplete as it was not big enough. In the past, candidates can answer as detailed as Lu ran wrote, it is rare.

But they didn't want to give Lu a perfect score. Today, their goal is to humiliate Lu ran, the ideal is to give each other zero points, how can it be so easy to add a ten to the front? No, something's wrong.

Ding! As expected, the emperor has lived up to his promise. He has indeed found a mistake for them, and it can be said to be a very serious mistake.

That's number seven. The topic is to write a "flow stone" extraction method.

Flow stone is a kind of semi-solid stone, said to be stone, because of high temperature or in dry air for a long time, it will become hard, like stone. This mineral is used to refine the body of certain weapons, such as guns.

The flow stone itself is rare, belongs to the precious mineral, in the Huai State City almost does not have. And the method of extraction, really is not in the scope of spiritual expertise, because the refinery is to get good mineral extraction, meteor extraction that is mining knowledge.

But the two teachers in order to beat Lu ran, naturally do not mind using this kind of cold and partial knowledge.

The answer to this question is also simple, because you only need to list one. However, Lu ran just listen to purple clothing random examples, picked the three most typical extraction method written, up is extraordinary play.

The first two "powder law" and "Water Law" , is the most common way, but also Huai Zhou City Library and the collection of the spirit association, can barely find the method.

The third is the "steam method" . Lu ran of course had not heard before, don't say Qi Fa, is the word stone he felt a bit strange. But the answer from the girl in Purple, I guess, was right, so he wrote it up.

Steam method describes the content of the stone, is sprinkled on the surface of silver powder, to high temperature to heat, as the temperature rose to a certain extent, the stone will directly vaporize after hardening. The silver remains the same, and the main component of the Stream turns to water vapor, which condenses when it meets the wall of distillation.

Well, it sounds a little like a high school chemistry experiment. Lu Ran said he didn't understand them, but he does now.

The two teachers were excited to see the steam extraction mentioned in this additional answer. Because as far as they know, rocks don't vaporize, liquids and Semisolids do. And when the stone is heated, it becomes solid.

"Ha ha, " teacher Zhang said with undisguised excitement. "Lu, you really know a lot of things, which has opened my eyes. But in this question, you made a serious basic mistake. I'm afraid we can't let you pass this test. "

"It's the vaporization extraction of the meteor, right? " Lu Ran said.

The three people listened to tiny tiny one zheng, did not expect Lu ran in the mind to understand. Strange. If you knew it was wrong, why did you write it? This problem only needs to list one kind, you just write the preceding kind of not?

Looking at a pair of curious face, Lu ran in the heart can not bear, then made kind-hearted.

"Of course, there is no record of the vaporization of the stones in such a small place as Huaizhou city, nor necessarily in the White Dragon City. But it is a method, and the key is the silver powder, which petrifies the outside of the stone, but keeps the fluid inside. As far as I know, this method has replaced the powder method and the water method in eastern war a hundred years ago."

According to... ? ... As far as you know. ? Three people looked at Lu ran's eyes, more and more full of surprise. Because of the manner in which he said it, he looked more like a master than a layman.

As for what he said, the three did not want to believe it, could not believe it, did not believe it immediately, but did not immediately refute it. Because judging from what they knew, the extraction method described by Lu ran had a similar application in other ores.

In addition, the eastern war is rich in stone tools, mining refiners and other skills in defiance of the world, there are many advanced production technology. Lu Ran's tone, if true, is not surprising.

"Of course, I can't prove it to you for a while, because I'm afraid I can't find the stone in Huaizhou. If you want to prove it, you can buy some in Bailong city or Phoenix and try it yourself. "

"Also, it doesn't really matter if I get a score on this one, because according to the instructions, if the part with more answers is wrong, the answer will be the correct part. "

Dang! The three of them were shocked. This last sentence of Lu ran's was, as it were, true. However, this provision is an additional note, only the test norms appear above, and the test norms have been lying in the box for more than two years, did not take out, how Lu ran know?

No, we have to make a last-minute play. What if they're bluffing?

"Master Lu, where did you see this rule, and why don't I remember it? " Teacher Zhang asked, looking sly.

"Oh, well, it's written in parentheses behind the title, " Lu Ran said, a harmless look: "The title of this paper, should be from two other places a title directly from the Bar? You can see the back even the date of Florida three years ago do not know to wipe. "

"What? This... this... "

Zhang teacher a series of "This" a few times, also no this so come, only personally confirmed, quickly turned back to stare hard-pressed teacher Li.

Li was not willing to lose, also stared back, said Harvard, I bought a table last year, you told me to rush time what do not mind, directly rubbing down on the line ah? What do I care what happens now?

"Zhang Teacher, now you remember? " Lu ran smiled.

"Oh, yes, yes, it does. "

Well, it has to. If it doesn't, it means he's old, his memory's failing, he's dying, he's retiring.

"Well, now that you remember, is the paper all right? "

"Uh... no problem, no problem. Well... Lu, you have a perfect score. "

Although 10,000 do not want to, although Zheng old eyes have been shot over, but Zhang teacher really had no way, had to admit Lu ran's paper full score. Yeah, and an honest man.

"with a perfect score, why don't you pull up the curtains and start identifying the apparitions. Or do you prefer to do it by candlelight? "

"Well... Lao Li! Hurry up and pull up the curtain, Lu is going to identify the spirit. "

Lao Li was still angry, so ordered, this time simply sitting still. Damn it, I'm your equal, and you're making a fool of yourself. What do I care? Who gave you the right to take it out on me?

This is... awkward. Zheng Lao as a leader, embarrassment that is also there, but more is not convinced. Written test has been, and the identification of the link, does not necessarily mean that Lu ran got the certificate Ah.

Thinking of this, he perked up, voluntarily pulled up the curtain, and summoned two teachers and Lu ran together to identify the spirit.

The spirit was lying on the table, surrounded by the rush of sunlight, emitting a dazzling light and rich spiritual energy. These are from the White Dragon City to take the standard, has the merit, the merit shortcoming, the examination is special.

"Master Lu, this second part is very simple. We will choose a spirit for you to identify and state its category, purpose, spirituality, and obvious advantages and disadvantages. We judge you on the basis of your results, and if you pass, you pass

"I understand that, but I am curious about it. " Lu ran looked at the two teachers calmly and said, "you are judged to be qualified according to my assessment, and who will judge whether your assessment is reasonable? "

The words immediately offended the three of them.

Our judgment needs judgment? You are clearly questioning the qualifications of the two teachers, in the doubt that the two teachers later may be favoritism, you qualified the evaluation results as unqualified.

And even though that's what we thought, and even though you were right to question it, we're still angry.

"Lu Childe, what you said is a bit not enough, isn't it? Who Am I, Wang so-and-so, to spite you on purpose? "

"That is, who am I, Li, to make trouble for you? "

"That is, who am I, Zheng? Would I deliberately make things difficult for you? "

When I heard the three-way battle, lu ran could not help but sneer at him in the heart: "Ha ha, what person also? "? It's not Tom, Dick and Harry, is it? What's Zheng Dong Zheng Xi? You won't deliberately difficult I, that just difficult I, it is three very thick-skinned pig? No, the pig's face is very thick, I think you can only be three pangolins

"three senior, junior dare not have this meaning. " He said with a smile: "How about this. This second link is used for the identification of the spirit, certainly has both advantages and disadvantages. I will tell you all the advantages and disadvantages of them, and you will compare them according to your own judgment. If they agree with each other, it means I'm as good as you. If there is a disagreement, we correct each other and consider it as appropriate."
