"It's highly flammable... but not easy to detonate."
Placed on the experiment table is an orange-yellow crystal.
It is an obviously finished cut and there are traces of knife marks around it.
"What is it for?"
"...It's complicated to explain, but you'll understand once you see it."
In Fang Wen's simple laboratory, there is a simple device.
It is a fixed crystal, tightly wrapped around its surroundings. Below it is a burning fuse, and above it, a large weightlifting dumbbell.
"Boom!"
Suddenly, the critical point is reached, and an explosion occurs.
"Boom!"
This time, it is the sound of the dumbbell flying and shattering the ceiling.
The explosion emits tremendous force in an instant, despite having only a small point of contact.
"How is it possible?"
This seemingly violation of physics surprises Lu Ping'an.
He picks up the crystal and finds no visible changes. The only difference is that the part connected to the fuse has some orange dust.
