Genius is just the threshold for me!

Around 5 p.m., the winter sun was hanging obliquely in the west.

Wang Rui led Xiao Yutong back to the Chengdu Aircraft Industry Group's residential compound and into a security booth on the side.

A security guard in his fifties with graying hair saw Wang Rui walk in, and then saw Xiao Yutong holding hands with him. He paused for a moment, then exclaimed with delight.

"Arui? You brought your girlfriend home... This girl is really beautiful, a perfect match!"

"Hello, Uncle Zhou!"

Wang Rui politely called out, then took out the ID card Xiao Yutong had given him: "I'm taking her home for a meal and to register."

"Yes, yes."

Uncle Zhou took the ID card, registered the name and ID number, and came back with a smile, saying, "Your mother, Engineer Su, is home this year, so it's a good opportunity to bring her back to make her happy..."

"Thank you for your help, Uncle Zhou."

Wang Rui took the ID card and handed it to Xiao Yutong, saying, "Once you're here, you're considered part of the inner park. You can only enter by applying on open days or by having someone register with you."

"That's so strict."

Xiao Yutong gasped softly, then, as if seeing something, tugged at Wang Rui's arm, gesturing for him to look to the right: "Aren't those the exoskeletons, powered armor, and combat robotic dogs that people are talking about online?"

"where……"

Wang Rui looked in the direction Xiao Yutong indicated.

Upon seeing Chen Jianhua and three security personnel wearing exoskeletons and accompanied by a mechanical dog approaching from the Chengdu Aircraft Industry Group's outer base, he immediately smiled and said, "Yes, these are the latest technologies researched by our Chief Engineer Lin."

I've heard that the latest generation of exoskeleton powered armor can amplify human strength tenfold. If it helps you sprint a few steps, you could carry an adult and throw them up to the third floor.

The combat mechanical dog can run at speeds up to 90 kilometers per hour, and its high-torque motor in its mouth can bite through human bones.

It is said that some of the unit's robotic dogs carry submachine guns, shotguns, and even suicide bombs in combat.

"Amplify the power tenfold?"

Xiao Yutong exclaimed with a hint of admiration, "Amazing!"

"It's impressive, but unfortunately it's all army equipment..."

Wang Rui nodded and then shook his head, saying with a regretful expression, "In modern warfare, the army is a sitting duck for the air force and navy."

Our naval strength is far too weak. We only have one aircraft carrier, the Type 001, and it doesn't even have a complete carrier-based aircraft system. But there's nothing we can do; developing the navy and air force is just too difficult.

[Remember the fastest online novel website: 202ᴋᴋs.ᴄᴏᴍ]

"A billion yuan can bring about earth-shattering changes in the army, while a hundred billion yuan won't even make a ripple in the navy or air force."

"So that's how it is."

Xiao Yutong held Wang Rui's hand and encouraged him, "It's okay, we can develop things slowly."

"Okay, let's go back quickly."

Wang Rui nodded and led Xiao Yutong home.

Ding-dong-

When we arrived at the 15th floor in the elevator, the elevator doors opened, and the motion-activated lights in the corridor turned on.

Wang Rui led Xiao Yutong out of the elevator and to the apartment on the left side of the corridor. They opened the door with a key, and a warm smell of cooking wafted out, a stark contrast to the cold temperature outside.

"Dad, Mom, I'm home."

Wang Rui took out a pair of shoes for Xiao Yutong, then took out his own shoes and put them on, before calling out to the house.

"You're back?"

A faint, joyful response came from inside the house.

Wang Rui and Xiao Yutong went inside. On the coffee table in the living room, there was a plate of melon seeds and a plate of candy. Wang Xingguo, who was wearing glasses, came out of the study.

"uncle!"

When Xiao Yutong saw Wang Xingguo, her body tensed up instinctively, but she maintained a calm expression and greeted him somewhat reservedly.

Ok?

Wang Xingguo's gaze subconsciously swept over Xiao Yutong's posture and small movements, especially the micro-expressions on her face, but after looking for a while and finding nothing unusual, he forced a friendly smile onto his face.

"Yu... Yu Tong, right? Sit down. Your aunt was cooking, and the soy sauce had expired, so she went downstairs to buy some not long ago... Xiao Rui, call your mom and tell her to come back quickly."

"Dad, don't look at people like that every time I bring them home."

Noticing Wang Xingguo's expression, Wang Rui waved his hand impatiently, led Xiao Yutong to sit down in the living room, took out his phone and dialed Su Ruohua's number. After asking a few questions, he said to Xiao Yutong, "My mom is on her way back, she'll be here in a bit."

"Yutong, have some tea."

Wang Xingguo poured a cup of tea to about seven-tenths full and placed it in front of Xiao Yutong, saying politely, "Let Wang Rui keep you company for a while. Uncle has some things to attend to. Your aunt will be back soon."

"It's alright, Uncle, you can go ahead and do what you need to do." Xiao Yutong quickly took the tea with both hands, looking a little nervous.

"good!"

Wang Xingguo nodded and was about to return to his study.

jingle--

Someone rang the doorbell.

"Mr. Wang, something's up." The doorbell camera activated, revealing Chen Jianhua's face, while a voice from outside also came through the walkie-talkie.

"Old Chen, what's up?"

Wang Xingguo walked over, opened the door, and looked at Chen Jianhua, asking, "Why are you in such a rush on the weekend? Wasn't it convenient to talk on the phone?"

"Xiao Rui is back?"

Chen Jianhua rushed in, bringing with him a gust of cold wind. He noticed Wang Rui and Xiao Yutong in the living room, and whispered something to Wang Xingguo behind their backs. Then he took out a document sealed with top-secret sealing wax and handed it to him.

"I see."

Wang Xingguo took the document with a serious expression, turned around and called to Wang Rui, "Xiao Rui, I have to go out for a bit and may not be back for dinner. Tell your mother when she gets back... There are some fresh cherries in the fridge, wash some for Yu Tong."

"understood."

Wang Rui responded.

Wang Xingguo nodded and left without lingering, going out with Chen Jianhua.

"Baby~"

Seeing Wang Xingguo leave, Xiao Yutong patted her chest and breathed a sigh of relief, saying, "Uncle was so serious."

"Just ignore him."

Wang Rui waved his hand and said, "He encountered spies a few times when he was young, and he has a psychological stress reaction, so he's used to treating everyone he meets as a spy. But after decades of this stress, he hasn't encountered any new spies..."

"Perhaps this is something my uncle's job requires to be kept strictly confidential."

Xiao Yutong responded and asked curiously, "The person who was looking for Uncle just now..."

"You mean Uncle Chen? He's been my dad's partner for decades. There might be some urgent matter if you're looking for him."

As Wang Rui spoke, he stood up, went to the refrigerator to take out a box of fresh cherries and a fruit platter, and then went to the water tap on the balcony.

"Have a seat for a while, I'll go wash some cherries. I usually don't buy fruit when I come home, but I'm only getting this today because of you..."

"it is good."

Xiao Yutong smiled and responded, then looked towards the corridor where Wang Xingguo had just come out. Noticing the restroom was in that direction, she stood up abruptly and asked, "Baby, can I use the restroom?"

"Sure, the bathroom heater switch is the second one. It'll be warmer if you turn it on in winter..." Wang Rui replied from the balcony.

"Okay, baby."

Xiao Yutong responded, avoiding Wang Rui's gaze, and saw the study with its door half-open on the right side of the corridor. She quickly took out the makeup powder compact she had gotten from the taxi, opened it, and scanned the area around the study door and the open door crack.

Once I was sure I didn't see any red or green spots of light on the mirror, I took out my phone and squeezed through the door without touching it.

Upon entering the study, one is greeted by a full bookshelf and a large table.

On the table were two computers and two closed military-grade laptops, and several men's and women's coats were hanging on the standing coat rack by the door.

Xiao Yutong looked at the electromagnetic shielding curtains that were completely drawn without a single gap, then looked at one of the computers displaying the standby password interface, and some files scattered in front of it.

Xiao Yutong turned on her phone's camera and pointed it at the document on the desktop. The CMOS electronic sensor precisely captured the optical information reflected from the document.

However, apart from a few documents placed to the side that clearly showed the text, the rest of the text was just a patch of irregular colored moiré patterns that completely obscured the writing.

"hiss--"

Xiao Yutong's pupils contracted slightly. She hurriedly peeled off the sticker on the phone's battery compartment, revealing a camera lens. Then she took out the lipstick she had gotten in the car and lifted one end to reveal a small LED.

Di-

Xiao Yutong turned on the switch to start the camera, twisted the lipstick, a red light flashed out, and then pressed the volume button on her phone to take a picture.

Then came orange light, yellow light, green light, violet light, infrared light, ultraviolet light... rapidly capturing photos of different spectra.

Thirty photos were taken in less than a minute.

Xiao Yutong put away her phone, didn't touch anything, squeezed out of the study, went to the bathroom, flushed, washed her hands, and touched up her makeup in front of the mirror with lipstick and powder.

After carefully touching up her makeup for over a minute, Wang Rui came over after washing the cherries. Seeing Xiao Yutong still busy, she couldn't help but ask, "It's almost time to eat, why are you still touching up your makeup?"

"I need to make a good impression when Auntie comes back..."

Xiao Yutong pursed her lips in front of the mirror to check the effect, put away her lipstick, and looked at Wang Rui with a smile, asking, "Does it look good?"

"very beautiful."

Wang Rui looked at it carefully for a while, then nodded with a smile.

Crack—

As the two were talking, the door turned slightly.

Su Ruohua came in with the keys and a bottle of soy sauce, calling out to the house, "Xiao Rui, come and take the soy sauce inside. I also have three dishes for you."

"..."

Wang Rui's lips twitched upon hearing this, and he said helplessly, "Mom, are you and Dad staying home or not cooking?"

"Whatever he cooks, I complain about him, and he complains about me."

Su Ruohua said irritably, but when she saw Xiao Yutong walking out, her face lit up with surprise and delight: "Yutong, right? She's even prettier than in the photos. No wonder my boy is so infatuated with her."

"Aunt……"

Hearing this, Xiao Yutong felt a little embarrassed and called out softly.

"There are a few more dishes; I'll leave them to Wang Rui to prepare."

Su Ruohua handed the soy sauce to Wang Rui, then enthusiastically pulled Xiao Yutong's hand and led her to the living room: "Come on, tell Auntie how you two met, what your parents do for a living, and today is the first time Wang Rui has brought a girl home as a guest..."
