I'm in Detective Conan, and I start with the Grand Theft Auto system.

When Lin Shen returned to Cafe 221B, it was exactly noon.

He pushed open the door and went inside. There were no customers in the store, only Mingmei sitting behind the bar, wiping a glass with a cloth.

When Akemi saw him return, she casually greeted him, "President, you're back? Have you eaten?"

Lin Shen tossed his car keys onto the bar counter, sat down, and asked, "Don't rush to eat."

"Mingmei, I have a question for you. What's the approximate price of RPGs and Gatling guns on the black market?"

Akemi paused, looking at him blankly. "RPG? Gatling gun?"

She blinked. "President, why are you suddenly asking this? How could I possibly know something like that?"

Lin Shen rubbed his temples, looking a little troubled.

He was so focused on taking orders that he took two huge orders: one hundred RPGs and one hundred Gatling guns. In the end, he didn't even figure out the cost price.

Why don't we just pick a random price?

Just as he was having a headache, the door was pushed open again.

Lin Shen looked up and saw Vermouth and Rena Mizunashi enter.

The two were dressed casually today, walking in one after the other, like ordinary customers.

Vermouth greeted him with a smile as soon as she entered: "President Lin, your coffee shop is quite hard to find."

Rena Mizunashi nodded slightly, "Sorry to bother you."

Lin Shen's eyes lit up. Perfect timing!

Mingmei didn't know, but those two intelligence agents definitely did!

He immediately came out from behind the bar and went to greet you, getting straight to the point: "You've come at the right time, I was just about to ask you something."

Vermouth raised an eyebrow: "Oh? What's making President Lin so anxious?"

Lin Shen didn't beat around the bush: "Do you know roughly what the prices of RPGs and Gatling guns are on the black market?"

Vermouth paused for a moment, then smiled: "President Lin, are you planning to switch to the arms trade?"

She thought for a moment, "I don't really know much about that. My intelligence is mainly focused on people, and I don't have much contact with weapons."

Rena Mizunashi picked up the conversation: "I do know a little about that."

As she spoke, she sat down at the bar. "It depends on the region. In areas with strict controls, like Tokyo, an RPG launcher costs about two thousand dollars, and a single rocket costs around three hundred dollars."

"Gatling guns are expensive, costing $75,000 each, and you might not even be able to buy one."

She glanced at Lin Shen and said, "These are all black market prices. Even if an ordinary person has money, they might not be able to get their hands on these goods."

"President Lin, why are you asking this?"

Upon hearing the price, Lin Shen was overjoyed.

He remained expressionless and casually replied, "It's nothing, someone just asked me to buy something."

But he had already quickly done the math in his head.

On Suzuki Tomoko's side, one hundred RPGs, even with a tenfold premium, would only cost $20,000 per unit.

One hundred aircraft would cost two million US dollars.

Add in the ammunition, and the batch she bought was at least a thousand rounds. At three hundred dollars a round, that's three hundred thousand dollars. Ten times that, it's three million dollars!

In total, five million US dollars.

On Tomizawa Tetsuji's side, 100 Gatling guns cost 75,000 each, so ten times that would be 750,000, and 100 would be 75 million US dollars.

Add in the cost of bullets, let's say one million dollars, for a total of seventy-six million.

Adding both sides together, it's 81 million US dollars!

Lin Shen was making plans in his mind.

Eighty million US dollars!

He almost burst out laughing.

It really is the arms industry that makes money!

Moreover, this is the kind of business that's incredibly profitable with no initial investment!

Lin took a deep breath, suppressing the barely suppressed smile on her lips, but the light in her eyes was impossible to hide.

Seeing his expression, Mingmei couldn't help but cough softly, reminding him to tone it down.

Vermouth noticed the unusual look on his face and tentatively asked, "President Lin, why are you asking this? Is someone trying to buy weapons from you?"

Lin Shen snapped out of his reverie and nodded slightly: "Yeah, more or less. Someone bought some things from me."

Rena Mizunashi's heart skipped a beat, and she immediately asked, "President Hayashi, it wouldn't be... President Tomizawa who asked you to buy it, would it?"

Lin Shen snapped his fingers and, without hiding anything, said, "You guessed right! It's Chairman Fu Ze. He said he wants to avenge his son."

Rena Mizunashi frowned slightly, but quickly relaxed without saying anything more.

Vermouth, however, was more interested in something else.

Her eyes widened, a look of astonishment on her face: "President Lin, I never imagined you had such unconventional methods! You even managed to get your hands on something like this?"

She looked Lin Shen up and down, her tone filled with exaggerated admiration, "Isn't that amazing? Among the people I know, there are very few who can get their hands on these things."

Lin Shen waved his hand: "It's alright, it's alright, it's mainly because we were lucky."

"I have a few friends serving at US military bases, and they can occasionally get their hands on some insider supplies."

Vermouth gave a meaningful "Oh," and said, "I see."

"No wonder, connections at US military bases are a real treasure."

She smiled and didn't press the matter further.

But these few words had already been memorized by Rena Mizunashi, who was quietly drinking coffee nearby.

She lowered her head, holding the cup, but her eyes were slightly narrowed.

US military base, insider goods!

If this news gets back, the CIA will definitely investigate!

Smuggling guns and ammunition, and even some powdered marijuana, is one thing!

They're even selling weapons of mass destruction like RPGs and Gatling guns now; those guys in the US military have really gone mad.

Lin Shen seemed oblivious to Mizunashi Rena's odd behavior, waving his hand dismissively. "Never mind that. What brings you two here today?"

Vermouth put down her glass and looked at him with a smile: "We're here to thank President Lin for sparing our lives last time."

She spoke casually, as if joking, but there was a hint of seriousness in her eyes.

Rena Mizunashi also came to her senses and added, "Yes, we were fortunate that President Hayashi showed leniency last time."

"If President Lin needs any help in the future, please feel free to contact me."

As she spoke, she took out a business card from her pocket and handed it to Lin Shen.

Lin Shen took it and glanced at it. It had the words "Rena Mizunashi, Announcer of Nichiri TV" printed on it, and a phone number below it.

"Okay, I'll take it." He put the business card in his pocket, smiled, and said, "Maybe we'll have a chance to work together in the future."

Rena Mizunashi smiled and didn't ask any further questions.

As they were talking, the door was pushed open again.

A woman walked in.

She was wearing a baseball cap, a mask pulled low, and a loose sweatshirt, looking like someone who wanted to keep a low profile when going out.

But as soon as she entered, she raised her hand and lifted the brim of her hat slightly, revealing the upper half of her lovely face—Yoko Okino.

She spotted Lin Shen at the bar and was about to greet him with a smile when her peripheral vision caught sight of Rena Mizunashi sitting next to her. She froze, then her face lit up with surprise: "Rena?! What are you doing here?"

Rena Mizunashi recognized her as well, a hint of surprise on her face: "Yoko? What a coincidence."

"I came here with a friend for a coffee, what are you doing here?"

Yoko Okino glanced at Lin Shen subconsciously, then quickly looked away, giving a slightly guilty smile: "I...I'm here to see President Lin!"

Rena Mizunashi glanced at her, then at Lin Shen sitting behind the bar, a meaningful glint in her eyes.

Then she just smiled and wisely didn't ask any more questions.
