I have been painting skin in the cemetery for fifteen years

(Thanks to my friend Kuangfeng Mingyue for being the new leader of this book)

Cannot answer!

This question cannot be answered!

Once the answer is found, people will die, and many people will die.

First of all, radioactive minerals are not mentioned in any alchemy textbook.

Menjief is already a master of alchemy, and his lecture notes have never mentioned any radioactive minerals.

In other words, radioactive minerals are completely blank for alchemy in the Eastern world.

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

Then how do you know Shen Wuque?

The previous policy questions and the like, that is amazing political comprehension.

The Luo Mengshu of the arithmetic department is a pure arithmetic problem. As long as you are talented enough, you can really solve any arithmetic problem.

But...alchemy is different.

Even if there is a genius in alchemy, it is absolutely impossible to know the unknown things by birth.

Alchemy is discovery.

After countless experiments, new substances and new phenomena were discovered. We stood on the shoulders of our predecessors and moved forward step by step.

And radioactive uranium ore is something completely unknown.

Even a genius who is against the sky cannot know it out of thin air.

Also, who murdered King Uz?

It is very likely the Western Church, because the other party's alchemy is more developed and advanced than Sky Academy.

So they mastered radioactive minerals and used this mysterious method to murder King Uz.

The reason is very simple, because King Uz sent Prince Saruman to Tianshui Academy to study, indicating his will to convert to Sky Academy.

This is a war of civilizations.

In order to prevent the Kingdom of Uz from falling to Sky Academy, the Western Church murdered King Uz and launched a coup to seize the throne while Prince Saruman was away from home.

Afterwards, the reformists represented by Wen Daozi sent a large number of elite talents to support Saruman and help Saruman regain the throne.

However, it was unexpected that after Saruman took the throne, he raised the butcher knife to the elite talents supporting Sky Book City and cleaned them up, including the son of Jiumogang.

Then, the brutal Roulan Massacre was staged, which caused the fall of the most important military town of Eastern civilization on the western border.

Saruman's betrayal and the Roulan Massacre also directly led to the complete failure of the Sky Book City reformists.

Wen Daozi and other pioneers of the reformists were exiled for a full ten years.

And the current Shen Wuque has become the life-saving straw of the reformists.

How do you know radioactive crystals, Shen Wuque?

Are you colluding with the Western Church?

Wen Daozi's reformists failed and were exiled. Do you feel resentment towards Sky Book City? So you have been bought by the Western Church?

Even Shen Gongao cannot escape suspicion.

Your Shen Gong family has hundreds of thousands of people, tens of thousands of troops, and tens of thousands of naval forces.

Where does the money come from for such war?

You trade with overseas every year. Who are these overseas?

In this trade process, are there any interests involved? Has your Shen Gong family been infiltrated by the Western Church?

The Western Church infiltrated the Imperial Dao Sect of the Dongyi Empire, and the Sky Book City is about to face a major defeat.

The Western Church has been regarded as the number one enemy.

It may be okay for others to answer it. Even if they are undercover agents of the Western Church, they may be bought by the Sky Book City. After all, they have united front value.

But Shen Wuque can't do it. Behind him are Wen Daozi and Shen Gongao. Any suspicion may be catastrophic.

What's more, the conservative faction of Mi Daoyuan and the Sky Book City will never miss this opportunity.

This question can't be done!

Wuque took a deep breath and put down his pen.

When he saw the score of this question, it was a full five points!

Damn!

It's crazy. The alchemy theory test with a total of 40 points accounted for five points on the last question.

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

It's possible to get full marks, but it's not.

But it's not okay not to answer.

So, Wuque made up an answer, saying that there is some kind of evil energy hidden in this crystal yellow flower.

A very powerful Yin-Yang master sealed the demon spirit in the crystal yellow flower.

Therefore, the crystal yellow flower will glow at night, which is similar to a ghost fire.

King Wuzi played with this crystal yellow flower day and night, but the demon spirit inside sucked his soul away, so he died tragically.

Alas, it's so serious, it seems to be true.

Not long after.

"Dangdangdang!" The bell rang, and the alchemy theory began to end.

All candidates stood up and turned their backs.

The examiner came forward to cover the name, then put the test paper into the envelope and wrote the number on the outside.

However, the alchemy exam is still not over.

Next, it's the experimental operation.

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

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

This kind of clothing covers the whole body, even the face, and glasses are also worn.

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

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

"During the entire examination, candidates cannot make any sound. The entire experiment is carried out in a fully closed state."

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

An alchemist examiner came on stage and took out a bottle with oily liquid in it.

In front of him, there was a pool of water.

The alchemist used a pair of chopsticks to pick up a piece of metal from the oily liquid.

The silver metal looked very much like silver and was about the size of a fist.

Then, he threw the silver metal directly into the pool.

Suddenly, the silver metal reacted violently, floating on the water and spinning continuously.

Then...

"Boom..."

The metal exploded suddenly, emitting flames.

Thirty examinees were stunned.

What... what's going on?

A metal that looks like silver actually explodes and burns when it comes into contact with water?

The alchemist examiner said: "You should have seen it clearly. Next, go back to your respective laboratories and use the instruments and materials inside to refine this explosive silver metal."

"The experiment is a total of 30 minutes. If it is completed within 25 minutes and the loss rate is less than 20%, it will be full marks."

"If it takes more than 45 minutes, it will be considered zero points."

Next, the 20 candidates entered their respective small laboratories.

It was crowded with hundreds of instruments and hundreds of materials.

"Alchemy experiment test, start!"

"Dangdangdang!"

The bell rang!

All candidates turned the hourglass on the table upside down. This is a 45-hour timer.

When the sand runs out, if the experiment is not successful, it will be zero points.

Today's alchemy test is really fucking difficult.

This alchemy experiment is at least much more difficult than the fire in water that Mendez gave him at that time.

For all candidates, the content of this experimental test was vaguely taught by the alchemy instructor, and there was also some content in the textbooks and handouts.

But...that was just a fragment of content.

Everyone only knows a little bit about the principle.

Now you actually ask everyone to refine this explosive metal directly. Isn't this too difficult?

This alchemy exam is really hell-level difficult.

This time, it's not just the alchemy that is difficult, but also the martial arts theory, formation, etc., which are all very, very difficult.

The entire Eastern world is facing a terrible challenge from the Western Church, and the good days before are over.

In the past, Sky Book City was strict and difficult in terms of learning, taking exams, or actual combat.

Otherwise, when the real decisive battle comes in the future, I'm afraid it will be a complete failure.

This experimental question is difficult for other candidates.

But for Wuque, it's too simple.

This mysterious explosive silver metal is just sodium metal. This metal is extremely active and will react violently when thrown into water.

If it's the size of a fist, it will explode directly.

For Wuque, it's even simpler than making white phosphorus last time.

It can be made using the Lussac method.

Take saturated and clear lime water (calcium hydroxide) and gradually add soda ash (sodium carbonate) until the precipitate stops increasing.

At this point, calcium carbonate and sodium hydroxide solution are successfully prepared.

Filter out the sodium hydroxide solution.

Next, accurately take out a portion of pure iron, add it to the sodium hydroxide solution, and heat it.

Finally, electrolyze the solution.

What amazed Shen Wuque here was how to electrolyze.

The earliest battery pack on Earth was in 1800, called the Voltaic pile battery pack. The chemical genius David used this primitive battery pack to electrolyze metallic sodium.

But in this world, there are no battery packs, but discharge creatures.

The alchemists, array masters, and Yin-Yang masters in this world all use electrical energy.

So, they cultivated a variety of discharge creatures, from strong to weak.

At this time, there are five kinds of discharge creatures in the laboratory, eels, rays, etc.

This is impossible on Earth because these discharge creatures are very unstable.

However, in this world, these discharge creatures are cultivated very stably, and they can discharge stably as long as they are stimulated.

Even their appearance is different from the electric discharge creatures on Earth.

This kind of electrolysis cannot use too high a voltage, so Wuque selected rays with a relatively low voltage.

Put a few small rays into a specific container, and then connect the positive and negative electrodes to the sodium hydroxide solution.

Press the switch of the container to stimulate the electric rays to continue to discharge.

Suddenly, a silver metal ball quickly formed, which looked silvery and shiny.

A few minutes later!

The reaction was over, and the metallic sodium in the sodium hydroxide solution was almost completely replaced, forming a thumb-sized metallic sodium, which really looked similar to silver.

Wuque used chopsticks to pick up the metallic sodium and immediately put it into a kerosene bottle, which had a special number on it.

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

As long as the experiment was successfully completed within two quarters of an hour, it would be full marks. Wuque only took half the time.

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

Several alchemist examiners were stunned when they saw Wuque.

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

"That's enough, you leave the examination room." said the alchemist examiner.

Wuque left, not making any sound from beginning to end.

At this point, the alchemy exam was officially over.

There was only one subject left in the entire city exam: the martial arts subject!

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