I put you in charge of those rebellious female soldiers, how come they all became top special forces

"That's interesting."

Chen Zheng unscrewed the thermos, blew on the few red goji berries floating on top, and took a sip.

This feeling is really good.

Boom, boom, boom.

A knock came at the door.

"Enter."

The door was pushed open.

Jiang Nan stood at the door.

She had changed out of the white dress stained with soy milk and dust, and put her training uniform back on, holding a large roll of blueprints in her hands.

"Instructor."

Jiang Nan walked to the table and placed the roll of blueprints on it.

"Just now in the car, you said you knew a little about explosives."

She deliberately emphasized the words "somewhat knowledgeable," her lips curving slightly upwards, a hint of provocation mixed with anticipation.

"I'm so grateful that you took me shopping, really."

"But in professional fields, one thing is one thing."

As Jiang Nan spoke, she spread out the blueprints with a whoosh.

It was a complex architectural drawing, densely covered with various data and red lines.

"This is a project I designed when I was in military school—a targeted demolition plan for a double-layer suspension bridge."

"The bridge is 800 meters long, and the main tower is made of high-strength reinforced concrete. There is a navigable waterway below, so the debris must not block the waterway during the demolition."

"My plan is to set up 300 linear cutting charges at the base of the main tower, and use time-delay detonators to detonate them in three stages, causing the bridge to collapse to both sides."

When talking about things she likes, she speaks very quickly, radiating a strong sense of confidence.

"To this day, I can't think of a better solution."

Jiang Nan raised her head, looked directly into Chen Zheng's eyes, and took out a red pen from her pocket and handed it to him.

"Instructor, since you're knowledgeable, why don't you take a look and tell me if there's anything that can be improved in this plan?"

Saying it's a request for advice is actually a form of arrogant defiance.

She emotionally accepted Chen Zheng, but professionally, since Chen Zheng had made the offer, she wanted to compete with him.

After all, if even the bomb-making instructors outperformed her, how could this genius possibly survive?

Chen Zheng leaned back in his chair, not even getting up.

He was still holding the thermos in his hand, his gaze fixed on the blueprint.

Only one glance, two seconds.

"Is this your perfect solution?"

Chen Zheng chuckled softly, shook his head, and casually pushed the red pen back.

"It's too rough."

Jiang Nan's expression froze.

This was a solution she calculated and simulated hundreds of times over two whole weeks!

"Instructor, you can't just say things like that." Jiang Nan frowned. "Every single loading point has been calculated using mechanical methods. Where is it rough?"

Chen Zheng took a sip of water to moisten his throat.

"Three hundred loading points, just laying the wiring would take an engineer three hours to complete."

"If it were a wartime assault mission, by the time you finished laying the lines, the enemy's tanks would have already been rolling across the bridge."

"But..." Jiang Nan wanted to argue.

"Wait, I haven't finished yet."

Chen Zheng extended a finger and pointed to the location of the main tower on the blueprint.

"You focused on cutting it at the base, trying to use gravity to make it collapse."

"The idea is good, but you overlooked the bridge's unique structure—the cable-stayed bridge."

"Once the main tower breaks at its base, the tension of hundreds of steel cables will instantly become unbalanced, and the resulting torque will twist the bridge deck, with the debris flying over an area of ​​at least 200 meters."

"At that time, not only will the river be blocked, but the houses next to it will also suffer."

Jiang Nan was stunned.

She quickly built a model in her mind, simulating the force situation at that moment.

A few seconds later, her expression changed.

The answer is yes.

Although the probability is only 15%, in precision blasting, this is already a major accident.

"Then...what do we do?" Jiang Nan's momentum instantly weakened by half. "Increase the cutting points? That would mean a larger payload..."

"Why cut it off?" Chen Zheng rolled his eyes. "Leverage principle, didn't you learn that in middle school physics?"

As he spoke, he put down his cup.

"Listen carefully, I'll only say it once."

"Three hundred points are not needed."

"Only six points."

Jiang Nan's eyes widened: "Six? That's impossible. That amount of explosives wouldn't even break through steel bars."

"Who gave you permission to blast the steel bars?"

"At the third load-bearing node of the main tower, at an elevation of 24 meters, drill a hole on the left side and fill it with C4, equivalent to 400 grams."

"Fill 500 grams in the symmetrical position on the right side."

"The total amount of explosives is less than one-third of your plan."

Jiang Nan was completely stunned.

Her brain raced as she began to calculate the data Chen Zheng had provided.

Chen Zheng gave two locations: one is the shear point where stress is most concentrated, and the other is the equilibrium point.

Once these two points detonate simultaneously, the main tower will not collapse directly, but will instead undergo a peculiar kneeling collapse due to its own weight and the tension of the steel cables.

It's like someone's knees suddenly buckled, causing them to kneel down.

The bridge deck would lose its support and slide entirely into the deep waters of the river, without any debris flying around!

This is simply a work of art.

Not only does it save more than 30% of the explosives, but it also requires only two people and can be deployed within 20 minutes!

When Jiang Nan looked at Chen Zheng, who was sitting there drinking tea, her eyes were filled with admiration.

She took a sudden step forward, placed her hands on the table, leaned forward, and her face was almost touching Chen Zheng's nose.

"Instructor! How did you figure that out? Teach me!"

She reached out and grabbed Chen Zheng's sleeve, wanting to extract everything from his mind.

This thirst for knowledge made her completely forget about propriety.

Chen Zheng frowned slightly as he looked at the outstretched hand.

"Sit still."

Jiang Nan froze, reluctantly withdrawing her outstretched hand and standing up straight.

"It's a combination of talent and experience."

"Want to learn?"

Jiang Nan nodded repeatedly: "Yes! I dream about it!"

"Then you should hone your basic skills."

Chen Zheng pointed to the blueprint.

"If you can't even find the stress points of this basic structure, giving you the best explosives is a waste."

"Go back and, following the approach I just described, redraw ten different demolition plans for the bridges."

"Give it to me tomorrow morning."

"Yes, sir! Mission accomplished!"

Jiang Nan answered loudly, grabbing the blueprints on the table as if they were priceless treasures.

She turned to run, but stopped abruptly at the door, turned back, and bowed deeply to Chen Zheng.

"Thank you, instructor! You're amazing!"

After saying that, she turned around and rushed out, not even bothering to close the door.

Her excited footsteps echoed down the corridor.

It's clear that this girl isn't going to get any sleep tonight.

The office returned to silence.

Chen Zheng looked at the empty doorway and a playful smile appeared on his lips.

He subconsciously raised his hand and touched his chin.

"It seems the rewards from this system are really something special."
