A song called "The You of the Past" has prompted the entire internet to beg me not to leav

Xinghai Public Security Bureau, Interrogation Room No. 1.

Cameras were installed on all four walls, and a high-wattage incandescent bulb shone brightly on the iron table in the center.

If an ordinary suspect sat here, their psychological defenses would crumble without even being asked.

however.

Lin Yan was sitting comfortably in the iron chair with his legs crossed.

Not only was she not wearing a silver bracelet, but there was also a steaming cup of goji berry and chrysanthemum tea in front of her, as well as a braised pork box lunch that she had almost finished.

"Smack smack".

Lin Yan picked up a piece of braised pork with alternating layers of fat and lean meat, stuffed it into his mouth, and mumbled his comments.

"Officer Zhou, the chef at the station's cafeteria is absolutely amazing! Did he use rock sugar to caramelize the sugar? The heat is just right. Could we have another bowl of rice?"

Across from the iron table.

Officer Zhou and several veteran detectives from the special task force felt their temples throbbing as they looked at this guy's carefree attitude.

Outside the door, six top criminal defense lawyers, hired by Shen Qingqiu at great expense, were completely blocking the deputy director's office, citing numerous historical examples to protest the police's infringement on citizens' rights.

Where is the person in question? They're showing off two boxes of braised pork!

"Lin Yan! Straighten your attitude!" Officer Zhou slammed his hand on the table. "This is an interrogation room, not a place for you to do a mukbang!"

He grabbed the remote control and pressed the button.

The screen on the side wall lit up instantly, displaying a direct image to the top-secret conference room of the Beijing Huaxia Archaeological Research Institute.

Sitting in the center of the screen was a sprightly old man with a full head of white hair, none other than Professor Sun Changgeng, a leading figure in China's archaeological community.

At this moment, the old professor stared intently at Lin Yan on the screen, his gaze so sharp it was as if he wanted to dissect him on the spot.

"You're that tomb raider?" Professor Sun suppressed his anger, his voice carrying an undeniable authority.

"Kid, let me ask you, how did you know how to break the anti-theft fire stone array in the stratum where the 'Warring States Silk Manuscript' was unearthed, as described in Chapter Three of your book? That's a top-secret discovery that our research institute unearthed last month in the Nanshan Tomb in Luoyang!"

The atmosphere in the room suddenly plummeted to freezing point.

Several detectives opened their notebooks, pens hovering over the paper, waiting for him to confess.

Lin Yan put down his chopsticks, took out a tissue, and slowly wiped his mouth.

"Professor Sun, right? I've heard so much about you." Lin Yan picked up his goji berry tea, blew on it, and looked helpless. "If I said that everything was just a figment of my imagination, you would definitely think I was joking."

"Bullshit!" Professor Sun slammed his hand on the table in anger, his beard trembling.

"‘To find the dragon vein, look at the winding mountains; each winding mountain is a barrier.’ This top-secret Tang Dynasty feng shui formula, coupled with the precise thickness of the quicksand layer down to the centimeter, you think you can fool me with such nonsense? Do you really think I'm a three-year-old?!"

"Confess honestly! Which tomb-raiding family did you learn from? How many tombs have you raided? Where do you sell your stolen goods?"

Officer Zhou also put pressure on him at the right time: "Lin Yan, confess and you'll be treated leniently. If you tell the truth quickly, it might count as a meritorious service for you."

Faced with the mixed doubles match, Lin Yan sighed and rolled his eyes.

Well, no one believes the truth when you tell professionals, so I can only use the magic of science students to defeat magic.

"Hey Zhou, can I borrow a whiteboard and some markers?"

Lin Yan suddenly stretched and finally stood up straight from the iron chair.

Officer Zhou paused for a moment, then gestured with his chin to the side, and a young officer immediately pushed the whiteboard over.

The moment Lin Yan grabbed the marker, his salty, uncouth demeanor vanished.

Unlike the nonchalant attitude of entertainment industry hustlers, he stood there with the stride of a top academic achiever on an international stage.

"Since you all insist on talking about logic, then I'll explain the logic to you."

Lin Yan casually drew a geological profile on the whiteboard.

"Professor Sun, you don't actually need to go down into the tomb to find things like the Firestone Array and the quicksand layer. All you need is a passing grade in junior high school science and a little knowledge of modern geology."

"First of all, Luoyang is located in the Yellow River basin, and the soil is mostly loess. To prevent theft, Warring States period tombs would have had their tombs built up beneath the earthen mound."

The pen tip danced across the whiteboard, and a series of crisp and clear physical formulas and chemical reaction equations appeared on the board.

"At a depth of about 15 meters underground, the soil moisture content and pressure reach a critical value. If I were the tomb owner, I would take advantage of the microporous properties of loess and lay a layer of roasted dry sand on it, which would become a quicksand layer."

"Quicksand cannot bear weight, and it will collapse as soon as it is dug. In such a confined environment, flint is placed. White phosphorus has an ignition point of about 30 degrees Celsius. Once it comes into contact with oxygen, it reacts violently and explodes directly."

Lin Yan turned around, pointed at the formula on the whiteboard with the cap of his pen, and shrugged.

"So, the method for breaking the formation in the book—using cold water to cool it down and adding weight with wooden boards—is based on the 'junior high school physics formula for friction' plus 'chemical oxidation reaction.' I did a quick derivation on some scratch paper; is it that difficult?"

The entire room fell silent.

Officer Zhou's eyes widened in disbelief. He had been handling cases for half his life, but this was the first time he had ever seen such a hardcore, science-based defense technique. His head was buzzing as he listened.

Professor Sun Changgeng on the other side of the screen suddenly widened his eyes, his lips trembling uncontrollably.

"Then... what about the Luoyang shovel for probing and color analysis?" The old professor's tone was noticeably weak.

"This is a freebie question," Lin Yan said casually, drawing a few circles on the side.

"It's the chemical reaction between iron and soil minerals. Tang Dynasty tombs mostly have red soil, while Han Dynasty tombs mostly have blue clay. Look at the color changes of the soil layers on the shovel, apply the principles of spectroscopy. I spent some time reading thousands of geological exploration papers before bed, did some big data analysis, and the patterns came out, didn't they?"

"As for feng shui and the Eight Trigrams..." Lin Yan added a Tai Chi diagram.

"To put it simply, it's ancient geomagnetism and microclimate science. The so-called 'observing the winding mountains' is about looking at the direction of geological fault zones. It's about deducing the auspicious feng shui sites of the ancients by following the movement of the earth's crust. This isn't tomb raiding; it's reverse engineering."

After finishing his fluent speech, Lin Yan casually tossed aside his marker, dusted off his hands, sat back down in his chair, and continued to enjoy his old man's tea.

"Read more books, read more newspapers, eat fewer snacks, and sleep more. Knowledge changes destiny—is what I'm saying reasonable?"

A deathly silence lasted for a full minute, as if the air itself had frozen.

The detectives who were about to take statements now held their pens like they were taking notes during a lecture by a famous professor from Tsinghua or Peking University, their eyes revealing a clear sense of stupidity and extreme shock.

On the large screen, Professor Sun Changgeng, one of the most authoritative archaeologists in China, stared intently at the derivation formulas on the whiteboard.

A perfect fit!

His hard-earned experience, gleaned from a lifetime of tomb raiding and eating dirt, was utterly dismantled in the interrogation room by a young man in his early twenties using only math and science?!

genius!

No, this is simply monstrous!

"You...you really have never been to a tomb?" Professor Sun's voice broke down completely.

"Yes, I have." Lin Yan put down his teacup, his eyes sincere.

The veteran detectives instantly perked up, thinking they had another job to do.

"Where did you get off?"

"I just dived 60 meters deep in the waters near the island a few days ago and caught a five-pound Chinese spiny lobster." Lin Yan blinked innocently. "Oh, so that counts as going to sea, not tomb raiding, right?"

Professor Sun felt a lump in his throat and almost spat blood onto the screen.

But as he looked at the densely packed calculus and high-energy physics formulas on the whiteboard, his doubts were completely shattered.

What a joke! If a god who understands this level of derivation formulas were to go tomb raiding, that would be a complete waste of talent! They'd be more than capable of building rockets!

"A misunderstanding... This is absolutely a huge misunderstanding!"

Professor Sun slapped his thigh suddenly, his face flushed with excitement.

"Captain Zhou! Release him immediately! Young friend Lin is not only not a suspect, he is simply a once-in-a-century genius in China's archaeological community!"

Officer Zhou wiped the cold sweat from his forehead and silently put down his notebook.

Half an hour later.

The iron door to interrogation room number one slammed open.

Outside the door, Shen Qingqiu took a deep breath, leading a top-notch legal team in suits behind him, ready to spend money to fight back and secure bail.

However, the next second, her CPU burned out.

Captain Zhou of the Xinghai City Criminal Investigation Detachment, known for his impartiality and incorruptibility, was all smiles as he saw Lin Yan out.

Lin Yan was even carrying the only two boxes of braised pork left in the bureau's canteen.

"Brother Lin, this is truly a case of the flood washing away the Dragon King's temple. When your 'Grave Robbers' Chronicles' gets a signed physical edition, please remember to save a copy for me! My son is a die-hard fan of yours!"

Lin Yan accepted the braised pork with complete ease, waving his hand with a smile: "No problem, no problem, Brother Zhou, please stay, don't bother seeing me out."

Shen Qingqiu was completely bewildered as he looked at Lin Yan, who was unharmed and even managed to smuggle out a boxed lunch belonging to a bureau chief.

What kind of evil magic did this guy use to turn the police captain who arrested him into a die-hard fan demanding more updates?!
