It didn't take long for the city guards to bring a barrel that hadn't been used.

Louis drew his sword directly, stabbed it in the barrel, and found some cotton wool to knead it into a simple fuse.

Flour was also found in the warehouse that had not been burned directly by the explosion.

I saw Louie pour the flour into the barrel, grab the barrel with both hands and a tail, and shake it violently.

Olivia was puzzled.

She didn't know what Louie wanted to do.

Louis looked at her and said:

"Do you know how to use fire magic?"

She glanced at it and knew that Louis was trying to set the barrel on fire.

So Olivia crossed her waist:

"How dare you underestimate the number one mage in the future world?"

"Okay, use fire magic to light the fuse...... me, Li Zaigan gods and demons? ”

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

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

While running again, he shouted to the royal guard:

"Get down, get down, don't get hurt by mistake."

Olivia's eyes widened as she looked at Louie, who ran away with her, and shouted:

"What danger can there be, isn't it just ......"

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

Willian, who was ready to defend, believed in Louis.

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

The blazing flames enveloped the explosion and slammed directly into the invisible barrier that William had unfurled.

William took a step forward.

The invisible wall collapsed in an instant, forcibly extinguishing the burning flames.

The little swan's dull hair shook and swayed, and after Louis put her down, she jumped up directly:

"See, even if it's a weakened fireball, I can hit an explosive injury...... Pain! ”

Louis directly Bang Bang gave the little swan two punches to the head:

"Let you light the fuse, I didn't let you blow up the barrel!"

"Also, it's 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 between his fingers and was blown away by the wind.

Olivia pouted.

Could she not know?

The moment she exploded, she realized that Louie had solved the mystery of the warehouse explosion.

Because she knew that she was not unleashing the Three-Ring Magic Fireball Technique, known as the "Low-Ring Spell Cannon".

Rather, it is a second-ring magic [Inferior Flame Orb] with lower damage and less coverage in spell spells.

Olivia went crazy to throw fireballs in her "house".

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

This spell has some piercing and heat damage, but it is undoubtedly not capable of causing such an explosion.

She looked at Louis with some confusion and confusion.

"Why does the flour in the barrel explode?"

Louie felt as if he saw a question mark on the door of the little swan's head.

He smiled and said:

"This is my previous ...... The old man of the village discovered the secret. ”

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

"Combustible dust forms a dust cloud with the air in a confined space."

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

"Some metal powders, wood chips, sugar, wheat flour, tea powder and other dusts can cause dust explosions."

"William, ask your patrolling brother if he smoked in private."

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

Louis nodded, then continued:

"I will later inform Beatrice that it is forbidden to carry fire in the future when entering this sealed environment."

He could guess that it was the guard who was addicted to smoking.

But it's not easy to take a bite in public.

So I simply took two bites during the inspection.

As a result, I didn't expect it to be dry this fall.

Even dust is more flammable.

This draw almost didn't take away his soul.

Looking at the appearance of everyone who didn't know what was going on, Louis didn't say anything.

He recalls his high school physics teacher.

Use the Tesla coil to summon thunder".

Balloons that are not afraid of nails.

Chopsticks and straws, who can pierce the potatoes.

Hit the stick inserted into the apple, whether the apple runs up or down.

Outdoor demonstration of how much damage a dust explosion can be.

Thanks to the entertaining teacher, Louis had a lot of love for physics.

- and then physics told him with reality that it didn't love him.

Ahem.

Looking back now, it was a nostalgic past.

So in the end, Louis scolded and chose to study liberal arts.

Behind many incredible things, it is often just that I have not learned enough, so I can't explain it.

Only Olivia glanced at Louis suspiciously.

"How did this guy get so smart now?"

Olivia looked at the royal guard, who was unclear but had a little more adoring expression.

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

As long as you know a lot, and even be able to exchange knowledge for tangible value, it is enough.

She wanted to cry without tears.

No, what's your situation with the confused country?

You weren't like that before!

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

Wait a minute!

Olivia's eyes sharpened.

If Louis originally knew about the dust explosion, why did this case in his previous life become a headless case?

Could it be that you are confused......

Secretly hiding?!

The little swan was furious.

Okay, you, you're a confused country.

If you have the ability, you don't need to put it in waste, right?

Just as she was filled with righteous indignation, another thought suddenly flashed through her mind.

"No, no, am I missing something?"

Olivia thought about it for a while, but she really didn't think of what was missing.

Suddenly, after seeing Louie, she quietly looked away.

There was a flash of lightning in my head.

"Ah, I see!"

"It's not that the country has become smarter, it's this guy...... I was lazy in my previous life, so I didn't come to the scene at all!"

Damn it!

Misguided.

She secretly cursed in her heart, "First of all, the ...... of the confused country who committed the sin of laziness".

As a result, he was still holy-presented to others.

Although she was a little unhappy, now that the truth has been discovered, she still praised:

"Louie, there is a high probability that what you said is the truth, but let's investigate it a little."

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

"There's got to be weird!"

Olivia said loudly.

A vague smile tugged at the corners of Louie's mouth.

Coincidentally, he also felt that something was wrong.

Everyone nodded.

Prince Louis found out the truth.

The second princess added details.

The two sides also reached a consensus on conclusions.

The royal guards and city guards only felt that their heads were itchy.

"You don't have to grow your brains, do you?"

But one thing they know for sure.

The wisdom of both empires has made such a judgment, so it must be taken seriously!

Examine!

It must be investigated!

Louie: "Did the little swan notice something? She's not as stupid as she thinks!"

Little Swan: "Hmph, at least it doesn't show that I haven't come up with a solution, right? As for whether there will be a mastermind behind it...... This matter has no effect on Sister Wang at all, okay?"

It's just that neither of them noticed.

In a group of royal guards, someone frowned and lowered his head, a hint of uneasiness flashed across his face.
