Not long after, the city guards brought an unused wine barrel.

Louis simply drew his sword, poked a hole in the wine barrel, and found some cotton wool, which he rolled into a simple fuse.

Flour that was not directly burned in the explosion was found in the warehouse.

Louis poured the flour into the wine barrel, grabbed the barrel with his two hands and his tail, and shook it vigorously.

Olivia was a little confused.

She didn't know what Louis was going to do.

Louis looked at her and said, "Can you use fire magic?"

She took one look and realized that Louis wanted to set the barrel on fire.

So Olivia put her hands on her hips:

"How dare you underestimate the future world's number one wizard?"

"Okay, use fire magic to light the fuse... Fuck, Li Zai Gan, the devil?"

Louis stared in amazement as the little swan threw a fireball directly at the barrel.

Without saying a word, he rushed forward, grabbed Olivia's waist and ran away.

While running, he shouted to the royal guards: "Get down, get down, don't get hurt by mistake."

Olivia stared at Louis who was running away with her in his arms, and shouted, "What kind of danger can it be? It's just..."

The next moment, the wine barrel that Louis had shaken suddenly exploded with a bang.

William, who was already prepared for defense, believed in Louis.

He had already raised his shield when Louis shouted, and a pale blue wall of fire unfolded.

The blazing flames, accompanied by an explosion, directly hit the invisible barrier that William had unfolded.

William took a step forward.

The invisible wall collapsed instantly, forcibly extinguishing the burning flames.

The little swan's hair was shaking. After Louis put her down, she jumped up directly: "See? Even if it's a weakened fireball, I can still cause explosive damage... It hurts!"

Louis punched the little swan on the head twice: "I told you to light the fuse, not to blow up the barrel!"

"Also, this is called a dust explosion, and it has nothing to do with your fireball!"

Louis grabbed a handful of flour from a bag, and the flour fell from between his fingers and was blown away by the wind.

Olivia pouted.

How could she not know?

The moment the explosion happened, she realized that Louis had solved the mystery of the warehouse explosion.

Because she knew that what she released was not the third-level magic fireball, which is known as the "low-level spell cannon".

Instead, it is the second-level magic [Secondary Fire Orb] in the conjuration system, which has lower damage and smaller coverage.

Olivia must be crazy to be throwing fireballs in her own "house".

If it gets burned, don't you have to pay for it yourself?

This spell has a certain degree of penetration and high temperature damage, but it will undoubtedly not cause this kind of explosion.

She looked at Louis with some confusion and bewilderment.

“Why does a barrel explode when you add flour to it?”

Louis felt as if he saw the question mark shaking on Little Swan's forehead.

He smiled and said, "This is a secret discovered by the old people in my old village."

Louis grabbed a handful of flour, which fell from his fingers and was blown away by the wind.

"The combustible dust formed a dust cloud with the air in the confined space."

"If someone ignites a fire in such an environment, the dust and air mixture will burn quickly and cause a small explosion."

"Dusts such as some metal powders, sawdust, sugar, wheat flour, and tea powder can cause dust explosions."

"William, ask your patrol brother if he smokes in private."

William said: "No need to ask, he does smoke a lot."

Louis nodded, and then continued, "I will inform Beatrice later that it is forbidden to bring fire into this sealed environment in the future."

He could guess what was going on and estimated that it was just the bodyguard who was craving for cigarettes.

But it’s not a good idea to smoke in public.

So I just took a couple of puffs during the inspection.

Unexpectedly, this autumn was dry.

The dust is also more flammable.

This pull almost took away my soul.

Seeing that everyone looked confused, Louis didn't say anything.

He recalled his high school physics teacher.

Use Tesla coils to summon thunder".

Balloons that are not afraid of nails.

Chopsticks and straw, who can pierce the potato?

Outdoors shows how harmful dust explosions can be.

Thanks to the teacher who taught in an entertaining way, Louis fell in love with physics even more.

——Then physics told him with reality that it did not love him.

Cough cough.

Looking back now, it is indeed a memory worth remembering.

So in the end, Louis chose to study liberal arts with a lot of curses.

Behind many incredible things, it is often simply because we have not learned enough, so we cannot explain them.

Only Olivia looked at Louis suspiciously.

"How did this guy become so smart now?"

Olivia looked at the royal guard who looked confused but with a hint of admiration on his face.

Sometimes, you don't even need money or force to convince someone.

As long as you know a lot and can even convert knowledge into tangible value, that's enough.

She felt like crying but had no tears.

No, what's wrong with you? You were obviously not like this before!

Why do you like to use your brain to solve problems so much now? !

etc!

Olivia's eyes sharpened.

If Louis already knew about the dust explosion, why did this case in his previous life become an unsolved case?

Could it be that you are confusing the country...

Hiding your abilities secretly?!

The little swan was furious.

Good for you, you are a country that confuses people.

You have the ability but you don't use it, you are just pretending to be useless, right? Just as she was filled with righteous indignation, another thought suddenly flashed through her mind.

"No, that's not right. Did I miss something?"

After Olivia thought about it carefully, she really couldn't think of anything she had missed.

Suddenly, after seeing Louis, she quietly turned her eyes away.

A flash of lightning flashed through my mind.

“Ah, I see!”

"It's not that Huoguo has become smarter, but this guy... was lazy in his previous life and didn't even come to the scene!"

hateful!

It was a bad idea.

She cursed in her heart, "It was Huguo who committed the crime of laziness first..."

In the end, he still showed his holiness before others.

Although she was a little unhappy, since she had found out the truth, she still praised him: "Louis, what you said is most likely the truth, but we still need to investigate a little bit."

"Even if there is flour dust in the granary, it shouldn't explode so easily."

"There must be something fishy about this!"

Olivia said with great force.

Louis's lips curled up into a hidden smile.

Coincidentally, he also felt something was wrong.

Everyone nodded.

Prince Louis discovered the truth.

The second princess added the details.

The two sides also reached a consensus on the conclusions.

The royal guards and city guards just felt itchy on their heads.

"You're not going to grow a brain, are you?"

But there is one thing they can be sure of.

Since the wise men of the two empires have made such a judgment, we must take it seriously!

Check! Must check strictly!

Louis: "Has the little swan realized something? She's not as stupid as I thought!"

Little Swan: "Humph, at least I can't reveal that I haven't come up with any solution, right? As for whether there is a mastermind behind this... this matter has no impact on Sister Wang at all, okay!"

But neither of them noticed.

Among a group of royal guards and city guards, someone frowned and lowered his head, a trace of uneasiness flashed across his face.
