(Thanks to the old friend of Storm Mingyue for reading the book and becoming the new leader of this book)

I can't answer!

This question cannot be answered!

Once the solution is solved, it will kill people, and many people will die.

First of all, in all alchemy textbooks, there is no mention of radioactive minerals.

Menjeff was already a master of alchemy, and there was never any mention of radioactive minerals in his lecture notes.

That is, for the alchemy of the Eastern world, radioactive minerals are a complete blank.

In other words, the top level of Sky Academy City has just recently solved the murder case of King Uzi and learned that there is such a terrifying luminous stone.

Then how do you know?

The previous policy topics and the like, that was an astonishing political understanding.

Luo Mengshu in the arithmetic department, that is, a pure arithmetic problem, as long as you are genius enough, you can really solve any arithmetic problem.

But...... Alchemy is not the same.

Even if alchemy has a genius, it is absolutely impossible to be born to know something unknown.

Alchemy is discovery.

After countless experiments, new substances and new phenomena have been discovered, standing on the shoulders of predecessors, moving forward step by step.

Radioactive uranium ore is something completely unknown.

Even if you are a genius who goes against the sky, it is impossible to know it out of thin air.

Also, Who murdered King Uzi?

It is likely to be the Western Holy See, because the other party's alchemy is more developed and advanced than the Sky Academy.

So they got their hands on radioactive minerals and murdered King Uzi in this unpredictable way.

The reason is very simple, because King Uzi sent the crown prince Saruman to study at Tianshui Academy, showing his will to convert to Sky Book City.

This is a battle of civilizations.

In order for the Western Holy See to prevent the Kingdom of Uzi from falling to the Sky Book City, it murdered the King of Uzi without doing anything, and took advantage of Prince Saruman's absence to launch a coup d'état to seize the throne.

After that, in order to support Saruman, the reformers represented by Wen Daozi sent a large number of elite talents to help Saruman regain the throne.

However, he never expected that after Saruman sat on the throne, the elite talents who supported the Sky Book City raised their butcher knives and cleaned them cleanly, including the son of Hatomogang.

This was followed by the Roulan Massacre, which led to the fall of one of the most important military towns of Eastern civilization on the western frontier.

Saruman's betrayal and the Roulan Massacre also directly led to the complete defeat of the reformers in Sky Book City.

Wen Daozi and other reformist pioneers were exiled for ten years.

And the current Shen Wuqian has become a lifesaver for the reformers.

How do you know about radioactive crystals?

Are you colluding with the Western Holy See?

When you heard that the Daozi reformers failed and were exiled, did you have a grudge against Sky Book City? So it has been bought by the Western Holy See?

Even Shen Gongao can't get rid of suspicion.

Your Shen Gong family has a population of hundreds of thousands, tens of thousands of troops, and tens of thousands of sailors.

Where does the money come from?

You trade overseas every year, who is this overseas exactly?

In this kind of trade process, is there an exchange of interests, and is your Shen Gong family infiltrated by the Western Holy See?

The Western Holy See infiltrated the Imperial Dao Sect of the Dongyi Empire, and saw that the Sky Book City was about to face a major rout.

The Western Holy See has been regarded as the number one enemy.

It may be okay for others to answer it, even if it is an undercover agent of the Western Holy See, it may be bought by Sky Book City, after all, it has united front value.

But Shen Wuqian can't do it, behind him is Wen Daozi and Shen Gongao. Any suspicion may be wiped out.

What's more, the conservatives of the Sky Book City will never let go of this opportunity.

This question can't be done!

Wufeng took a deep breath and put down the pen.

Look at the score of this question, a full five!

My day!

It's crazy, a total of forty points for the alchemy theory exam, and the last question accounts for five points.

I can do it, but I can't do it.

It can be a full score, but it can't be a full score.

But you can't answer it.

So, Wu Jian made up an answer, saying that there was some kind of evil energy hidden in this spar yellow flower.

A very powerful onmyoji sealed the demon spirit into the spar yellow flower.

Therefore, the spar goldenrod will shine at night, which is similar to a ghost fire.

King Uzi played with this spar flower day and night, but was sucked out of his soul by the demon spirit inside, so he died tragically.

Alas, it's so carefully written, as if it's real.

Soon after.

"Dangdang, dang!" The bell rings, and the theory of alchemy begins to end.

All candidates stand with their backs to the past.

The examiner stepped forward to paste his name, then put the exam paper into a sealed bag and wrote the number on the outside.

However, the alchemy exam is still not over.

Next, it's time for experimentation.

"All candidates, enter the secret room and put on alchemy protective clothing."

Wu Feng and the thirty candidates entered the secret room, picked up the alchemy protective suit and put it on.

This kind of clothes cover the whole body, even the face is completely covered, and he also wears glasses.

Therefore, during the experiment, the identity can be kept absolutely confidential, which has the effect of fascinating.

After putting on the protective clothing, enter the experimental examination room.

"During the whole exam, the candidates cannot make any sound, and the whole experimental process is carried out in a closed state."

"All alchemy candidates, please look at the question!"

An alchemist examiner stepped up to the stage and pulled out a bottle containing an oily liquid.

In front of him, there is also a pool.

The alchemist used a pair of chopsticks to pull out a piece of metal from the oily liquid.

The silver metal, which looks really similar to silver, is about the size of a fist.

He then threw the silver metal directly into the pool.

Suddenly, the silvery metal reacted violently, floating above the water, constantly spinning.

Followed by......

"Boom ......"

The metal exploded violently, emitting a flash of fire.

The thirty candidates were stunned.

This...... What's going on?

A metal that looks like silver will explode when exposed to water, and it will deflagrate?

The alchemist examiner said, "You should have seen it clearly, and then go back to your respective laboratories and use the tools and materials inside to refine this deflagrated silver metal." ”

"The experiment was thirty points in total, completed in two quarters of an hour, and the attrition rate was less than twenty percent, which was a perfect score."

"More than four quarters of an hour is considered zero."

Next, twenty candidates entered their respective small laboratories.

It is densely packed, hundreds of utensils, hundreds of materials.

"Alchemy Lab Exam, Begin!"

"Dangdang!"

The bell is ringing!

All candidates, turn the hourglass on the table upside down, which is a four-quarter hour timer.

When the sand is finished, the experiment has not been successful, and it is zero points.

Today's alchemy exam is really difficult.

This alchemy experiment was at least much more difficult than making a fire in the water that Menjeff gave him at that time.

For all candidates, the content of this experimental exam is faintly taught by an alchemy instructor, and there is also some content in the textbooks and handouts.

But...... That's just fragments.

You've only learned a little bit about it.

Now you're asking everyone to directly refine this deflagration metal, isn't it too difficult?

This alchemy exam is really hellish difficulty.

This time it is not only the alchemy department, but also the martial arts theory department, the formation department, etc., which are very, very difficult.

The whole Eastern world faced a terrible challenge from the Western Holy See, and the good old days were over.

In the past, whether it was studying, starting exams, or actual combat, Sky Book City was all strict and difficult.

Otherwise, when the real decisive battle comes in the future, I am afraid that it will be defeated.

This lab question is difficult for other candidates.

But for Wuji, it's not too simple.

This mysterious deflagration of silver metal is nothing more than metal sodium, which is extremely reactive and reacts violently when thrown into water.

the size of a fist, then it will explode directly.

For Wuji, it is even simpler than the last time white phosphorus was prepared.

It can be obtained by the Lussac method.

Take saturated and clear lime water (calcium hydroxide) and gradually add soda ash (sodium carbonate) until the precipitate does not increase.

So far, the solution of calcium carbonate and sodium hydroxide has been successful.

Strain out the sodium hydroxide solution.

Next, a portion of pure iron is precisely removed, added to the sodium hydroxide solution, and heated.

Finally, an electrolytic solution is sufficient.

And what amazes Shen Wujian here is how to electrolyze.

The earliest battery pack on earth was in 1800, called the voltaic stack battery pack, and the chemical genius David used this primitive battery pack to electrolyze metal sodium.

But in this world, there are no battery packs, and they are actually discharged organisms.

The alchemists, array mages, and onmyoists in this world will all use electricity.

So, they have cultivated a wide variety of discharge organisms, from strong to weak.

At this time, in the laboratory, there are five types of discharge organisms, eels, rays, and so on.

This is not possible on Earth because these firing organisms are very unstable.

However, in this world, these discharge organisms are cultivated to be very stable, and as long as they are stimulated, they can stabilize the discharge.

Even their appearance is not the same as that of the discharged creatures on Earth.

In this kind of electrolysis, you can't use too high voltage, so you have selected rays with relatively small voltage.

A few rays are placed in a specific container, and the positive and negative electrodes are inserted into the sodium hydroxide solution.

Press the switch of the container to stimulate the electric ray to discharge continuously.

Suddenly, a silver metal ball quickly formed, appearing silvery white and shiny.

A few minutes later!

At the end of the reaction, the sodium metal in the sodium hydroxide solution was almost completely replaced, forming a thumb-sized sodium metal, which really looks similar to silver.

Wu Que used chopsticks to clip out the metal sodium and immediately put it into the kerosene bottle, which has a special number.

At this point, less than a quarter of an hour had passed.

As long as the experiment is successfully completed within two quarters of an hour, it is a perfect score, and it only takes half the time.

He took the kerosene bottle, walked out of the laboratory, went to the outside examination room, and handed it to the alchemist examiner.

Several alchemist examiners were stunned when they saw Wu Defect.

This...... It's been less than a quarter of an hour.

"Alright, you leave the exam room." The alchemist examiner said.

Leave without defects, without making any sound from beginning to end.

At this point, the examination of the alchemy department is officially over.

There is one last subject left in the entire school city exam: martial arts!

This subject will determine the final ranking, and it will also determine the fate of Shen Wujian and Fu Tieyi.

……………………

Note: The second more is sent, the guaranteed monthly ticket in the hands of the brothers, vote for me, okay?

Thank you for bowing to you.
