Dust Explosion

The white marble chess piece was tossed into the air by "Robin Hood." Neither Alain's men nor Toga's Clones paid any attention to the small stone, letting it fall towards Alain in a parabolic arc. Then, the chess piece exploded in the center of the room!

Like a hand grenade, the chess piece "queen" suddenly exploded from within mid-air, like a small firework, with sparks of light scattering into the air along with marble dust...

The explosion wasn't loud, but everyone in the room stopped in their tracks, staring blankly at the ball of flame.

... Is this the "beware of grenades" that Robin Hood was talking about? Its power is probably only comparable to a firework explosion.

No, that's not all! The air is filled with abnormally high concentrations of tobacco molecules, marble powder, and open flames...

"Get down! It's a dust explosion!"

Among the crowd, only Adams' pupils contracted, and he suddenly awoke with a roar. With a speed that defied his physical condition, he tackled Alain to the ground and slammed his head hard into the earth!

Seeing their leader attacked, Alain's two men hesitated, neither stepping forward to intercept Robin Hood nor stopping Adams, standing there unsure of what to do.

But soon, they felt a surge of heat and immediately realized what Adams meant, and they lunged towards the ground!

Although they moved quickly, it was already too late. They watched helplessly as the heatwave rushed towards them, like moths to a flame, their bodies facing the fire head-on...

A dust explosion refers to a chemical reaction in which a dust cloud formed by combustible dust mixing with air in a confined space is rapidly ignited by an ignition source, causing a sharp increase in temperature and pressure.

The conditions for a dust explosion are very demanding. First, the dust itself must be flammable or explosive, suspended in the air and mixed with air or oxygen to reach the explosive limit. Second, the space where the dust exists must be a confined space, in short, a sealed room. Finally, and most importantly, there must be an ignition source that can produce an open flame, just like igniting gunpowder to ignite the dust.

The smell of tobacco in the room had long since blended completely with the air, reaching a critical point for ignition. The marble dust and open flames acted as catalysts in this room, where the door had only recently been opened and the smoke had not yet dissipated, igniting the dust in a short time and creating a powerful man-made bomb!

Like a fire dragon raging through the room, the explosion generated temperatures that instantly reached hundreds of degrees Celsius. Even the people in the room who were lying on the ground had their clothes ignited by the dust they carried, turning them into charcoal in an instant, and their skin was also scorched red!

Especially Alain, whose fur ignited when embers touched his clothes, the flames began to scorch his hair. He tried to stand up, but Adams held him down firmly. "Don't move, the next explosion will be even stronger!"

A characteristic of dust explosions is that they produce multiple explosions. The initial blast wave blows up the dust deposited on equipment or the ground. Shortly after the initial explosion, a negative pressure forms in the explosion center, allowing fresh air to rush in and mix with the dust, thus triggering a secondary explosion. During the secondary explosion, the dust concentration is even higher.

Fortunately, tobacco is only denser than air. Some tobacco drifted out after the door was opened. The density of tobacco mixed with air in the lower part of the room was not high. Lying on the ground was the fastest and most effective way to avoid the dust explosion.

"Boom, boom, boom!"

The continuous explosions lasted for several seconds. Although the explosions were very strong, apart from the first wave of explosions which caught them off guard and caused explosions on their dust-covered bodies, the subsequent waves did not cause much damage to those of them lying on the ground, except for tinnitus, headaches, and being pressed down by the heat waves.

The explosion came and went quickly. After the flames on Alain's body were completely extinguished by the blast wave, they finally waited a while and confirmed that the explosion was over.

The surrounding air remained intense, like an oven that had just stopped heating; the high temperature was still uncomfortable. By now, the room had become a chaotic mess, like a scorching hell. The tables, chairs, and everything else in the board game room had lost their original function, either falling apart or turning into black charcoal of unknown origin.

Adams got up from the ground and the first thing he did was check on Alain's men. He felt their breathing and pulses and breathed a sigh of relief, "Your two men have burns, but they're not fatal. They're just unconscious like the others who were knocked down in the room earlier. You can rest assured about that."

Adams checked on the other unconscious people. Their condition was roughly the same as Alain's men. They had not suffered any fatal injuries, and although their breathing was weak, it was very stable. It wouldn't be a problem to leave them here unattended.

It should be said that Quirk has enhanced human physique. Injuries that once required emergency hospital treatment are now just non-fatal minor injuries. Burns and explosions generally do not kill people. Even if someone is seriously injured, it is possible for a doctor with a magical Quirk to miraculously bring them back from the brink of death.

Because people don't die easily, many don't cherish their bodies, and fighting and brawling have become the main themes in this world.

"Robin Hood... that guy, is that his name?" Alain looked at the burned-out room and Robin Hood had long since vanished without a trace, his expression grim and uncertain. He staggered to his feet, seemingly not seriously injured, but his face showed no sign of relief. His gentleman's clothes were tattered, and his tail, which had been hidden under his clothes, was now completely burned off. The rest of his body was also patchy and bald, like the ground after a bombing raid, making him look extremely disheveled and ashen-faced.

Adams was equally disheveled, but his expression remained quite calm, showing no signs of agitation even in his current predicament.

"He ran away? Well, he probably intended to use this to create an opportunity to escape..." Adams sighed. "Using a dust explosion to injure someone is a very rare act in the Age of Quirk."

Although Adams was caught up in the attack, he didn't resent Robin Hood much. After all, his only goal was to escape, not to kill anyone, and there was nothing to criticize about that. For a detective like him, getting injured was already commonplace.

In Quirk society, most crimes rely on the individual's unique Quirk and various functional support equipment; it's rare to see anyone using such a mentally charged method for indiscriminate attacks.

This is what made Adams interested in the character of "Robin Hood".
