A young boy from the 1970s, separated from his family, fled famine and led his younger brother into

"Nianci, from which book did you learn these theories about the 'greenhouse effect'?"

That evening, Lu Nianci was in her room organizing the notes left by her teacher, Gu Jiusi.

Lu Xingzhou suddenly pushed the door open and entered.

In his hand was a greenhouse design drawing she had made earlier.

Lu Nianci became secretly wary.

She knew that Lu Xingzhou was testing her again.

Ever since the vegetables in the greenhouse began to thrive, Lu Xingzhou has shown an increasingly strong curiosity about her "source of knowledge".

He had asked her this question more than once.

But Lu Nianci always used the ever-reliable excuse of "the book left by her father" to brush it off.

"Brother, didn't I tell you? I learned it all from the books Dad left behind." Lu Nianci blinked innocently.

Lu Xingzhou remained silent.

He simply walked over to her and placed the design drawings on the table.

His slender fingers gently tapped the dense formulas and symbols on the design drawing.

"Did your father teach you all this?" His voice carried a subtle sharpness.

Lu Nianci's heart tightened.

She knew that Lu Xingzhou was not so easily fooled.

These design drawings contain a wealth of knowledge in geometry, mechanics of materials, and structural engineering.

This knowledge is considered a highly specialized field, even in universities.

Even the smartest five-year-old child cannot master it out of thin air.

"Of course!" Lu Nianci raised her little face and said, pretending to be proud.

"My dad is amazing! He's not only good at fighting, he can also build houses!"

He said that building a house is like fighting a war; it requires strategy, precise calculations, and making good use of the properties of each material!

She attributed all the "irrationality" to her father, Su Weiguo, who had already sacrificed himself but was portrayed as a "god of war" in everyone's hearts.

Although the reason was impeccable, Lu Xingzhou's eyes were still full of scrutiny.

"Is that so?" he said casually.

"Did your father teach you these things?"

He pointed to a spot on the design drawing.

"This semi-circular dome structure is known in architecture as an 'arch'. It can evenly distribute the load to each support point, thus withstanding greater pressure."

"But even so, it could still collapse in Harbin's frigid cold and snow."

"Therefore, you designed 'diagonal braces' and 'tension bars' here to convert horizontal thrust into vertical pressure, thereby greatly increasing the stability of the structure."

He raised his head, his eyes deep and bright.

"This is not just ordinary knowledge about 'building a house'."

"This involves a very specialized field of structural mechanics."

Lu Nianci was startled.

She hadn't expected that Lu Xingzhou had such a deep understanding of architecture.

His words had almost completely exposed her pretense.

"Brother, how...how do you know so much?" Lu Nianci asked, feigning surprise.

Lu Xingzhou chuckled softly.

"Over the years, I have also been involved in some engineering and construction projects on the border."

"So, I have some understanding of these things."

He looked at Lu Nianci's young face, which was both innocent and wary.

He knew that she was hiding many secrets.

But he didn't want to pressure her.

He just wanted to know just how "extraordinary" she could be.

"Since your father taught you these things," Lu Xingzhou said, pointing to the design drawings again.

"Then can you tell me what the load-bearing limit of this 'arch' is?"

"How strong a wind can it withstand? And how many centimeters of snow can it withstand?"

He posed one professional question after another.

These questions require complex calculations to answer, even for a professional architectural engineer.

But Lu Nianci did not hesitate at all.

She picked up a pencil and quickly scribbled on the design.

She muttered a series of formulas and data to herself.

"Based on the material's compressive and tensile strengths, as well as the radius of curvature and span..."

"Without considering fatigue and aging, this dome structure can theoretically withstand a gale of level 8 and a meter of snow."

She raised her head, her bright eyes filled with confidence.

"Of course, this is just theoretical data. In actual use, we need to leave enough safety margin."

Lu Xingzhou's gaze sharpened.

He hadn't expected that Lu Nianci could calculate these data so quickly and accurately.

This is no longer as simple as "seeing it in a book".

This requires an extremely deep understanding and application of materials science, structural mechanics, and even fluid mechanics.

"You...you really just read it in a book?" Lu Xingzhou's voice trembled slightly.

Lu Nianci blinked innocently.

"Yes! Dad has so many books! They have all sorts of things in them!"

She knew she couldn't reveal the secret of her rebirth.

She could only attribute everything once again to her father, who had long since sacrificed himself but was deified by the masses.

Lu Xingzhou remained silent.

Looking at Lu Nianci's innocent little face, he was once again deeply moved.

He knew she wasn't telling the truth.

But he also knew that she had her own secrets.

He didn't ask any further questions.

He simply reached out and gently ruffled Lu Nianci's hair.

"You little girl, you're really... a devil." His voice carried a hint of helplessness, but also a hint of doting.

"However, since you're so capable, I'll test you again."

He took a small metal part out of his pocket.

It was a somewhat complex mechanical part, engraved with small numbers and symbols.

"Do you know what this is?" He placed the part on the table.

Lu Nianci picked up the parts and examined them carefully.

She discovered that the part was made of a very special material, seemingly a new type of alloy.

The numbers and symbols engraved on it also looked somewhat familiar to her.

"Is this... a component of an aircraft engine?" Lu Nianci asked tentatively.

Lu Xingzhou's pupils suddenly contracted.

He didn't expect that Lu Nianci could recognize the purpose of the part at a glance.

He brought this part back from a secret mission.

It is a new type of aircraft engine, currently still under development and classified as a top state secret.

Even he only knew its uses, but had only a superficial understanding of its specific structure and principles.

"How...how did you know?" His voice was full of shock.

Lu Nianci feigned composure and said, "My father's books also contain many blueprints for airplanes! I've seen similar structures!"

She knew this was her last chance.

She had to attribute all the "irrationality" to her "military god" father.

Looking at Lu Nianci's innocent yet confident face, Lu Xingzhou felt a mix of emotions.

He knew that she was hiding a huge secret.

But he also knew that this secret might have some hidden connection to the "water ghost" he was investigating.

He didn't ask any further questions.

He simply put away the metal part and gave Lu Nianci a deep look.

"You little girl, you're a real...treasure." His voice carried a complex emotion.

"However, since you enjoy reading so much, I will bring you some special 'books' in the future."

"I hope you won't let me down."

After he finished speaking, he turned around again and left the room.

Looking at his somewhat heavy back, Lu Nianci felt a surge of excitement.

She knew that Lu Xingzhou's "test" had not exposed her.

On the contrary, it earned her more trust and "resources".

Those "special books" he mentioned might be the key for her to understand this era, this world, and the "water ghost."

She picked up the notes left by Teacher Gu Jiusi again, her heart filled with anticipation for the future.

She knew that her knowledge would be her greatest weapon in this era.

She must learn and grow up as quickly as possible.

Only then can we cope with all the challenges that may arise in the future.
