Reborn in 2010, the AI ​​in my mind is too powerful.

Chen Yiran never considered himself to be an impatient person, but he knew very well that he was the kind of person who wouldn't be able to eat if he didn't play with a new toy right away.

After leaving the San Mateo County Sheriff's Office, he said goodbye to Richard and Linda, and Chen Yiran hurriedly turned on the navigation, preparing to head straight for the gun shop.

Linda quickly stopped him: "Mr. Lin, this, your FSC certificate, is needed to buy a handgun."

Chen Yiran took it, stuffed it into his pocket, stepped on the gas, and drove off.

He had already chosen the target gun shop, which was also recommended by Richard.

Los Altos Rod & Gun Club is a club in San Jose that, of course, sells guns. The greyish-white concrete building is tucked away in a corner of an industrial area, surrounded by dense woods and soundproof walls.

The cars in the parking lot were all high-end, including a Mercedes-Benz S550 and a BMW 750Li. There was also a Tesla Roadster parked in the corner. These days, this car is definitely a rare sight. The people who drive this are definitely among the first to try it out in Silicon Valley. Chen Yiran's bulletproof G55, however, didn't look out of place parked there at all.

Pushing open the heavy, soundproof door, the interior decor is a stark contrast to the understated exterior. A deep red Persian carpet stretches from the entrance to the innermost area, walnut wainscoting extends to the ceiling, and leather sofas form a seating area. In one corner sits a Jura espresso machine, with Belgian caramel biscuits on a small saucer beside it.

The air was filled with a faint smell of gunpowder and cigar smoke, much like the atmosphere of an old-money club in a novel.

The wall is adorned with commemorative plaques from the past century, as well as bronze plaques and certificates of appreciation presented by former police chiefs, retired generals, and industrialists.

An elderly gentleman with gray hair walked out, wearing a crisp white shirt, gold-rimmed glasses, and a nameplate on his chest that read "Frank".

"Sir, how can I help you?"

"Buying guns, probably a lot of guns."

"Of course, please follow me to the gun selection room."

I walked through a corridor and pushed open a soundproof door. The room was small, with a dark blue velvet tabletop covered in oak wood, and a reading lamp casting a soft glow on the surface.

Chen Yiran's posture is very similar to a scene from the movie John Wick.

"Please have a seat. Coffee or tea, please?"

"Iced Coke, please."

Frank hesitated for a moment, but still rang the bell to have an iced cola delivered.

"What type of movie would you like to watch?"

Chen Yiran still asked for outside help: "Jasmine, what models of guns did I see recommended online?"

After clearing his throat, Chen Yiran began to state his requirements.

"Let's start with a pistol. SIG Sauer P226 Elite Dark, 9mm."

Frank turned around, opened the display case behind him, and took out the gun, placing it on the velvet: "A new product from SIG in 2010. The E2 ergonomic grip system, with a grip angle optimized by five degrees compared to the old model, allowing even shooters with smaller hands to control it perfectly. Pure double-action trigger, short-return hammer, the military version of this gun is the sidearm of several special forces units in California."

In his previous life, Chen Yiran had also fired guns, but he bought a basic Glock pistol. After trying it out, he felt that it was not much different from a Glock.

"I'll take it. And another Springfield, 4.5-inch barrel, 9mm."

"Made in Croatia, this series was just released in 2009. Its biggest selling point is the standard 19-round magazine, although in California it can only hold 10 rounds. It has a triple safety mechanism: grip safety, trigger safety, and firing pin safety, providing an extra layer of physical protection compared to Glock. The sight line is almost an inch longer than other pistols of the same size, and its first-shot accuracy is among the best in its class."

Chen Yiran was too lazy to try it out, so he simply acted like a nouveau riche and told them what gun he wanted without even testing it.

"Ed Brown Custom Kobra Carry, .45 ACP."

Frank's actions were noticeably more serious; he took a gun from the innermost steel display case and put on white gloves.

The gun barrel, illuminated by the reading light, gleamed with a dull metallic sheen. The snake-scale pattern on the slide was finely and evenly engraved, with the edges of each scale shimmering slightly in the light. The grip's beaded anti-slip surface was densely packed with thousands of tiny protrusions, giving it an old-fashioned, profound feel under the light.

"Handcrafted by Ed Brown in a private workshop in Perryville, Missouri, each one is individually numbered. Commander size 1911, 4.25-inch barrel. This one features a Snake Eye tactical rear sight, allowing for aiming in low light without a flashlight, and a fiber optic front sight that automatically illuminates in sunlight."

"I need another one, an S&W M627, a performance-tuned version, .357 Magnum."

Frank pulled out a revolver, its eight-round cylinder gleaming a dark blue under the reading light: "In the era of semi-automatic pistols, an eight-round high-capacity revolver was a marvel. The double-action trigger, deeply tuned by the performance center, is as smooth as any custom-made 1911. And the biggest advantage of a revolver is that it will never jam."

"Alright, let's pick two more rifles, and a few shotguns too."

"Please speak."

After fussing around for over twenty minutes, Chen Yiran added more items to her shopping list: the Daniel DDM4V7 LW Limited Edition, the LMT Defender Law Enforcement Commemorative Edition, the Benelli M4 Tactical, the Remington 870, and the Serbu Super-Shorty.

"Okay, including the bullets you requested, the total after tax is $19000. I need your identification information. After registration, you can come and pick up the goods in ten days."

Chen Yiran, with a rather flamboyant air, pulled several items from his pocket and placed them on the table: a CCW license, the blue police cooperation ID card, and an FSC certificate.

Frank looked down and saw the official seal of the San Mateo County Sheriff's Office clearly visible.

Being an experienced person, he smoothly replied, "Understood. Usually, the exemption application is approved within a day. You can sit for a while, and I believe I will be able to deliver the packaged guns to you soon."

Chen Yiran sat down on the sofa next to him and watched Frank make a phone call. Three minutes later, he started helping Chen Yiran pack the boxes.

"Mr. Chen, Los Altos Rod & Gun welcomes you back anytime. If you require special ammunition, optical accessories, or further customization, please call my private number."

"OK."

For the next few days, Chen Yiran went to the San Mateo County Sheriff's Department's tactical training center for training every day.

Most men aren't averse to shooting. This was Chen Yiran's first time encountering so many different kinds of firearms, and with professional police trainers. He was very excited for several days, undergoing daily CQB simulation training.

The San Mateo County Sheriff's Department has a very large training facility, complete with indoor shooting ranges, simulated field exercises, and simulated street environments.

But most men are jerks, and after a week, Chen Yiran felt that the novelty of the gun had worn off.

However, the police instructors treated him very well and taught him all kinds of training very seriously.

They even introduced him to a K9 police dog trainer they knew and took him to the Cooper House K9 working dog base.

This is a professional police dog training base located in the mountains, run by a group of veterans. Besides supplying dogs to various law enforcement agencies and training working dogs, they also help Silicon Valley millionaires train their ultimate guard dogs.

Chen Yiran ordered two female dogs for Pidan, a German Shepherd and a Malinois. The dogs won't be delivered for several months. But when they arrive, they'll be the kind of violent dogs that can wear tactical helmets and bulletproof vests, and react with lethal force in milliseconds.

Having met so many police officers, and even training together regularly, Chen Yiran felt a little embarrassed to suddenly quit.

Otherwise, there's always this feeling of giving up because you can't stand the training.

Fortunately, Chen Yiran, who hadn't been to the company for ten days, received a call from Gao Dewei. The exasperated old man strongly demanded that Chen Yiran start working more seriously. Not only was she not coming to work every day, but she also didn't reply to MSN messages promptly, and now she wasn't even attending the Friday meeting.

Chen Yiran went down the slope, said goodbye to the instructors he knew, and thus ended his short-term military-like training.

It was Friday again, and Chen Yiran arrived at the company early.

He spoke with the air of a boss, expressing his appreciation to everyone who had worked hard for two weeks. He also announced that the company would be providing employee benefits, and that he had already reached an agreement with the San Mateo County Sheriff's Department. Anyone who wanted to train could go for training.

The male employees were mostly excited and reacted positively. The female employees were also quite accepting, chattering about learning about firearms so they could buy guns for self-defense.

After the commotion subsided, Chen Yiran called Gao Dewei into his office.

It's been three weeks since we started working on deep learning, including those few days at the exhibition. Aside from occasionally replying to a few messages, he's basically left the company to Gao Dewei. Today is the time to sit down and hear about the progress.

Gao Dewei leaned back in his chair, giving the lazybones a look of disdain: "Should we start with the good news or the bad?"

"Bad."

"The bad thing is that during the time you were away, Lin Zhiwei rewrote the LEF parsing of adaptec1, which was about 40% more complex than expected, and we had to re-adapt our entire backend pipeline."

"Okay then?"

"Let me finish. Adaptation is tough, but once it's done, it runs. Our parsing speed is about 30% faster than Synopsys'. We rewrote the memory management from scratch, so there's no legacy baggage. In other words, although the front-end took longer, the back-end actually runs faster."

"This is bad news? Then tell me the good news quickly."
