Oh no! I've only been a freshman and I've already been targeted by a mean upperclassman.

Li Chen walked back to his seat, sat down, and picked up his chopsticks.

Yan Xi remained in the same spot.

The posture remained unchanged.

There was still a little less than half a bowl of soup left in the bowl in front of me.

She looked at him.

There was a trace of red on Li Chen's hand.

It wasn't blood; it was friction marks from a fist striking the jawbone.

Yan Xi reached out and took his right hand.

I turned it over and checked the joints and knuckles.

"No bones were broken."

"I know what I'm doing."

"The angle of the punch was off by two degrees."

"You should get cheekbone augmentation."

"The reaction force from the jaw causes greater wear and tear on your metacarpophalangeal joints."

Li Chen looked at her.

"Are you teaching me how to hit someone?"

"I'm correcting your punching angle. Efficiency comes first."

Li Chen looked at her.

"Aren't you angry?"

"What are you angry about?"

"I did it."

"You said last time in the ancient town that the good thing was that you didn't take any action."

Yan Xi released his hand and picked up the soup spoon.

"Those three people were just blocking the way last time; they had dirty eyes but didn't reach out. This time is different."

She took a sip of soup.

"Once you reach out your hand, it's no longer within the realm of reasoning."

Li Chen didn't reply.

He finished the last of the noodles in his bowl.

She then took the pork cartilage that Yan Xi hadn't finished eating from her bowl and put it into her own.

Don't waste what you're not going to eat.

"I'm stuffed."

"You consumed less than 700 calories today."

"A bowl of noodles at the noodle shop costs about 450 yuan, and you ate two-thirds of it."

"Adding that morning's tea isn't enough."

Yan Xi put down the soup spoon.

"Are you counting calories for me?"

"Your BMI is 0.3 points low. I remember that."

Yan Xi looked at him for three seconds.

"You started calculating my calories five minutes after you hit me."

"Hitting someone and calculating calories are not contradictory."

Yan Xi stood up.

"Let's go, to the lighthouse you mentioned."

Li Chen paid the bill; it was twenty-four yuan for two bowls of noodles.

He left an extra twenty dollars on the table.

The boss saw it and said, "No, no need."

Li Chen had already reached the door.

Yan Xi was half a step ahead of him.

She didn't turn around, but stretched her hand behind her back.

Li Chen grasped it, their fingers intertwined.

The two people walked out of the noodle shop.

Sunlight streamed onto the stone pavement, and the sea breeze swept up from the bottom of the cliff.

My phone vibrated.

Li Chen took it out with one hand.

Group 302.

He didn't send any messages, but Wang Qiang did.

[Wang Qiang: Li Chen, have you arrived at the noodle shop yet? Did you take any pictures?]

Li Chen sent a photo of the noodle shop's exterior.

I typed an extra line.

[Li Chen: The noodles are delicious. Someone got into a fight.]

three seconds.

[Wang Qiang: ? ? ? ? ? ? What? ...

[Chen Mo: Please provide the background of the event, the number of opponents, the number of times you attacked, and the areas you struck. I need to refine your behavioral model.]

[Zhao Zixuan: Wait. You said you hit someone. Where's your sister-in-law? Is she alright?]

[Li Chen: She's teaching me how to correct my punching angle.]

ten seconds.

Wang Qiang: This couple is not human.

Li Chen locked the screen and put the phone back in his pocket.

Yan Xi walked to his left, against the wall.

Her hand was still in his. He didn't let go.

I walked twenty meters.

Yan Xi suddenly spoke.

"You didn't hesitate when you threw the punch."

"Um."

"Most people would warn you first. You didn't."

"His hand is already outstretched. The warning window has passed."

Yan Xi pressed her thumb on the web between his thumb and forefinger.

"Next time, don't hit the chin, hit the chest."

"It has a large surface area, so it's less likely to hurt your hand."

Li Chen looked down at their clasped hands.

Throughout the entire process of him clenching his fist, punching, and then being turned over by her to check his joints, her heartbeat remained steady.

"Aren't you afraid at all?"

Yan Xi did not stop walking.

"What are you afraid of?"

She turned her head to look at him, a smile in her eyes.

"You are."

The path behind the noodle shop was more difficult to walk than I had expected.

Gravel and weeds.

There are waist-high shrubs on both sides.

There are shallow gullies on the road surface, washed out by rainwater, no more than fifty centimeters wide.

Yan Xi walked ahead.

She walked a little slower than usual.

It wasn't because the road was difficult to walk, but because she was looking at the vegetation and geology on both sides.

"The bedrock in this area is volcanic tuff. The weathered layer is about two to three centimeters thick."

"Could you please not give an academic presentation while you're out?"

"cannot."

Li Chen followed behind her.

His attention wasn't on the geology; he was looking at the road surface.

Where each step lands, which stones are loose, and where there is standing water.

It took about ten minutes to walk.

The bush suddenly broke.

At the end of the road was an open space, and at the end of the open space was a cliff.

A lighthouse stands on the edge of the cliff.

Not tall, seventeen meters.

A gray concrete cylinder.

The surface coating has mostly peeled off, revealing the original dark gray concrete underneath.

The sea breeze has etched lines and patterns onto the surface.

Like tree rings.

The fence was made of iron and it was rusted.

Most of it is still there, but a section on the west side is crooked.

The iron railings were twisted by external force, creating gaps large enough for a person to squeeze through sideways.

Yan Xi stopped five meters in front of the lighthouse.

Her gaze swept upwards from the base, all the way to the lighthouse at the top.

"1956. The concrete grade should be between C15 and C20. Prestressed concrete technology did not exist at that time; it was all plain concrete."

"The fact that it has lasted this long shows that the construction quality is quite good."

Her tone turned somber.

Li Chen didn't disturb him.

He walked to the gap in the fence on the west side and checked the spacing and stability of the iron railing.

"It's passable. You go first. I'll follow behind."

Yan Xi walked over.

She turned to the side, her shoulder brushing against the crooked iron railing.

My fingers touched the metal surface as they passed by.

"The rust depth is about 1.5 millimeters. It can last for a few more years. But if it exceeds 3 millimeters, there will be structural risks."

"Are you here to have fun or to get an expert report?"

"Yes, all of them."

Li Chen then stepped aside.

The lighthouse's iron gate was open, but the lock was broken.

There is graffiti on the door panel.

Blurred, washed away by wind and rain, leaving only some colorful traces.

Yan Xi pushed open the door and went inside.

Inside is a spiral staircase, made of cast iron.

There was sand and dead leaves on the steps.

The air was filled with the salty smell of the sea and the damp smell unique to concrete.

She stepped onto the first step.

A metallic resonance echoed from beneath my feet, reverberating through the cylindrical space.

Are the steps stable?

"A cast iron spiral staircase. The connection points with the wall are made of expansion bolts. There is no looseness."

Yan Xi inspected the wall as she walked up.

Her fingers occasionally touched the concrete surface, her fingertips tracing the rough texture.

Li Chen followed two steps below her.

When you get to the third floor, there is a small window on the wall.

The glass shattered, and the wind howled as it rushed in through the window.

Yan Xi paused at the window and looked outside.

sea.

From this height, the curvature of the sea surface can already be perceived.

The horizon is not straight; it curves slightly at both ends.

"What are you looking at?"

"Curvature".

"The curvature of sea level?"

"Seventeen meters high. Visual range approximately fifteen kilometers. Curvature change is on the critical line that is visible to the naked eye."

"You're calculating again now."

"This is called estimation."

Li Chen reached out from behind her, placed his hand on her waist, and gently pushed her.

"Keep going up. The top is the key."

Yan Xi turned her head and glanced at him, but didn't say anything and continued walking.

The spiral staircase ends on the fifth floor.

A rusty iron gate.

The door wasn't locked.

Pushing it open reveals the lighting room platform.

It's not big, just over three meters in diameter.

In the middle is the base of the lamp; the lamp itself is still there.

Glass cover, Fresnel lens.

It's over sixty years old; the lens surface has cracks, but its shape is intact.
