"Couldn't you have said what you wanted to say earlier? Why have you been so restless, refusing to say it?"
Artoria looked at Sherlock Holmes with a strange expression.
"It's simple. If Miss Fujimaru intends to return, then there is no point in revealing these truths. I dislike doing meaningless things."
"Then let me explain exactly how the evil Professor Moriarty intends to destroy this planet."
Adjusting his bow tie, Sherlock Holmes cleared his throat.
"If this world has already been severed from human history, then the safeguard Leonardo mentioned earlier—the Counter Force—will no longer function here."
"However, destroying a planet is something that should not be possible to begin with. This is Shinjuku. What is being controlled is Shinjuku. No matter how thoroughly Shinjuku is controlled, it cannot destroy the entire planet."
"Therefore... shall you explain the rest, or shall I?"
Sherlock Holmes looked at the kind-hearted Moriarty.
"I will."
Moriarty swung the leg he had crossed over the other.
"In any plan to destroy a planet, many things can be absent. But there is one thing that absolutely cannot be lacking."
"That is [energy]."
"The energy needed to destroy a planet is indispensable."
"It must be concentrated at a point in Earth's core—a [point] capable of causing the planet to collapse."
"Is the theory simple?" Moriarty shrugged. "But the problem lies here—achieving such a thing requires an unimaginably vast amount of energy, and from within Earth, we simply cannot produce that much energy."
"So at that point, one needs an 'external force.'"
"An external force?" Fujimaru Ritsuka looked confused.
"Master, you know about meteorites, don't you? The kinetic energy a meteorite provides could absolutely destroy a planet if it struck the right place. But once again, there is a problem—the point where a meteorite lands cannot be fixed,
