Zizhuyuan.

Luo Xingchen looked through the arithmetic book from Yajili.

From the beginning, it was Yageli writing.

This is not the translated Qi text, but the original Yajili version.

"This book is quite interesting."

However, Luo Xingchen understood Yajili's writing, so there was no big obstacle when reading it.

From this book, Luo Xingchen could get a glimpse of Yajili's current level of arithmetic development.

Overall, it is much stronger than Qi.

No wonder Yajili's warships and weapons are stronger than those of Qi. In a country that values ​​science and technology and arithmetic, development is inevitable.

Those who fall behind will definitely be beaten.

Luo Xingchen admired his mother Yang Ruoqing very much.

Her vision is stronger than most people in Qi.

If she hadn't established a science and technology park to develop new warships, new artillery, fire guns, etc., the gap between Qi and Yajili and other countries would have become wider and wider.

And now Qi is also catching up, and even surpassing it in many aspects, without falling behind in everything.

"Brother Luo, this is my manuscript. There are many problems that I can't figure out."

Later, Yue Yueling took out another manuscript.

There is a thick stack of manuscripts, full of beautiful small characters and various arithmetic lines.

For someone who doesn't know much about arithmetic, reading this manuscript would be like reading a book from heaven.

But in Luo Xingchen's view, these are relatively elementary and not too difficult.

Yue Yueling took out a few pictures from it.

"These are the questions."

"Don't worry, wait for me to take a look."

Luo Xingchen took a pen and paper, looked at it, smiled slightly and said: "I think these questions are quite profound, I can answer them for you."

He had already seen Yue Yueling's problem.

It's not that Yue Yueling's thinking ability is insufficient, but that her arithmetic level is insufficient. There are many things that can be calculated without relying on her personal ability.

After all, even extremely smart people learn arithmetic by standing on the shoulders of their predecessors.

The intelligence of the predecessors is not inferior to that of modern people. They have some seemingly simple conclusions. It may take them a lifetime, or even an occasional flash of inspiration, to achieve something.

"If you want to solve these questions, you must first understand what irrational numbers are..."

Luo Xingchen began to answer, starting with irrational numbers.

During the simple narration, Yue Yueling's eyes became brighter and brighter.

“So it can still be like this!”

She had a feeling of enlightenment, which was like an enlightenment.

This time I met Luo Xingchen, and I really saw the right person.

Otherwise, how could she know and have this knowledge?

I kept talking for nearly two hours.

Luo Xingchen's mouth felt dry as he spoke, and he picked up the tea cup at hand from time to time and took a sip.

Let him, Yue Yueling, sit upright, holding a pen and doing calculations on paper.

"I figured it out."

After finally overcoming another difficult problem, Yue Yueling shouted happily.

"Yes, you have talent in mathematics." Luo Xingchen nodded happily.

Not everyone in this world is gifted. For some people, even if he talks for three days and three nights, he still cannot make some people understand even the simplest questions.

Yue Yueling is obviously not that kind of stupid person.

On the contrary, Yue Yueling's talent in mathematics and physics is not weak, and he is a talent that can be made.

"I'm hungry, so I can't forget it anymore." Yue Yueling put down the pen and paper.

I glanced at the sunshine outside, and it was obvious that it was already noon, and time flew by so fast!

"Zhishu, Mo Hua, are lunch ready?" Yue Yueling shouted loudly.

"Miss, are you ready? Are you going to serve the food now?" Zhishu walked in quickly from outside.

"Let's serve the food now." Yue Yueling said.

The dining table is placed in a nearby wing.

After the food was placed, only Luo Xingchen and Yue Yueling were eating.

"Try it and see if it suits your taste?" Yue Yueling asked.

"Not bad, authentic Beijing cuisine." Luo Xingchen nodded.

These dishes are not the taste of the north, but the taste of the Qi capital.

It can be said that Yue Yueling prepared very carefully and found a cook who was good at cooking Qijingcheng cuisine in advance.

"As long as Brother Luo likes it," Yue Yueling said with a smile.

"If you still need my help, just tell me directly. I'll help you if I can. Don't blame me if you can't."

Luo Xingchen took a few bites of the food, put down his chopsticks and said.

As for whether Yue Yueling is okay, Luo Xingchen thinks that there must be something wrong.

Yue Yueling prepared so meticulously and followed his preferences, it was impossible just to ask a few math questions.

There must be something else going on.

"Brother Luo is indeed as sharp as a candle. He can't hide anything from you."

Yue Yueling pursed her lips and continued: "There is something I don't know who to tell..."

After a short moment of silence, Yue Yueling seemed to have made up her mind.

"I suspect that some of my brothers have become traitors, and others have evil intentions." After Yue Yueling finished speaking, he looked at Luo Xingchen, waiting for his answer.

Luo Xingchen smiled slightly: "I thought it was some bizarre event."

"Your brother has a traitor. Not only did you discover it, but your father, Marshal Yue, had also noticed it for a long time."

"My father also knows? Then who is the traitor?" Yue Yueling said hurriedly.

"Who exactly is it? Your father has several suspects, but there is no definite evidence." Luo Xingchen knew this from the last time.

"No matter which one it is, father will be very sad." Yue Yueling lowered his head and said.

This is where she is in trouble.

"My father has eighteen adopted sons, and only three of us are biological ones. But in my father's eyes, the adopted sons are no different from the biological ones."

"Brother Zhan Ge, he became a general and a young marshal not because of his status as a biological son, but because of his military exploits. The other brothers, who are adopted sons, were also promoted to generals based on their military exploits."

"If father confirms that one of them, or more, has become a traitor, he will be very disappointed and sad." Yue Yueling said.

"Having said that, we must first settle down the domestic situation before fighting against foreign aggression. If there is confirmed evidence, Marshal Yue will not mind killing relatives out of justice." Luo Xingchen said.

"I want to help my father and help him find the traitor." Yue Yueling said.

"Have you told Marshal Yue? If you take action rashly and ruin his plan..." Luo Xingchen said.

"I won't ruin his plan. I will lay a trap to lure the traitors in, but I don't have enough force and I can't find anyone else."

"Brother Luo is an imperial envoy of the imperial court and will never collude with traitors, so it is safe to leave it to Brother Luo." Yue Yueling looked at Luo Xingchen with pleading eyes.

"What's the plan? Can you tell me about it?"

"It's impossible for me to collude with traitors."
