Lord of the Desert

Chapter 244 Heart Wave
The next day, in the afternoon.

Xijing Asahi Prefecture.

In the side garden, endless summer flourishes.

The water in the pond is green, dotted with ripples.

The flowers fall with the wind and bloom in the heart of the wave, blurring the reflection of the people in the pavilion.

On the stone table, carefully written papers were scattered.

Hong Fan checked in turn and browsed the content again.

This time the article is very thick, about geometric optics and Gaussian optics.

The former contains four basic laws of light propagation.

The law of straight line propagation of light:
Light travels in a straight line in a homogeneous medium.

The law of independent propagation of light:

The two beams of light do not interfere with each other when they meet on the way of propagation, and continue to propagate according to their respective paths; and when the two beams of light converge at the same point, the light energy at that point is simply added.

Laws of Reflection and Refraction:
When light encounters a smooth interface between two different media during its propagation, one part is reflected and the other part is refracted.

The principle of optical path reversibility: no matter how many reflections and refractions a beam of light starts from a point, if it encounters an interface reflection at a right angle to the beam at the end, the beam must exactly return to the starting point along the original path.

Then, it is part of Gaussian optics that Hong Fan involved in the high school physics competition and the big object course.

Gaussian optics is an "ideal optical system".

That is to say, for an optical system that can form a perfect image and an ideal image with a sufficiently wide beam of light at each point in a large enough space, it can be attributed to the problem of "collinear transformation" or "collinear imaging" mathematically.

At the end of the theory, Hong Fan also gave a sketch of a relatively modern optical microscope structure.

Most of the above-mentioned written content has been mastered by Qi Zuojian, and some of them are even the results of Zhuang Liren's work.

But for the integration and review of the theoretical system, it is also of great significance.

After sorting out the article, Hong Fan carefully bound it and planned to send it to Zhuang Liren tomorrow.

Then, he took out another piece of paper, rubbed the ink for a rare occasion, and wrote with a brush.

[Zhenghe 28th July [-]th, His Excellency Jin Haihong Fan Jingshu Gongheng...]

This is a letter that was agreed last year.

After spewing hundreds of words, Hong Fan wrote down the address of Chaori Mansion, and finally signed his name.

Then he fetched wax, sealed the envelope after softening it with Yanliujin, and called Mr. Tang to find a reliable messenger to send the letter.

It's settled.

Hong Fan went back to his room, changed into his martial arts uniform, and went to the martial arts arena.

As soon as he entered the back garden, he saw Zhan Yuanzi moved the table outside the house and was painting with a brush.

"Hong Fan, come and see my painting!"

Zhan Yuanzi heard the footsteps, raised his head and called out.

Hong Fan leaned over to have a look.

The ink marks on the drawing paper outline not the scenery in the garden, but a gorgeous pavilion.

Behind the railing, the veil was rolled up, and the woman looked down.

"Do you recognize it?"

Zhan Yuanzi asked, expectantly.

"Shen Tiexin?"

Hong Fan replied.

Artists love to paint landscapes.

Shen Tiexin is undoubtedly beautiful.

"You really recognized it! Is it a portrait of a person?"

Zhan Yuanzi asked again.

"It's like a painting of a pavilion."

Hong Fan answered truthfully.

"I guess so……"

Zhan Yuanzi sighed.

"This Shen girl is dressed in white and has white hair. Ever since I saw her, I wanted to draw some of her spirit."

"But maybe it's limited by the technique, maybe it's limited by the color, or maybe she's too beautiful, no matter how much she tries, it doesn't make sense."

He said and put down his pen and ink.

"Forget it, I'll follow you to practice swords."

The sun was strong and the wind was steaming.

The two used the iron hand and the Tianxin swordsmanship separately, and each performed their exercises a few times, both sweating a little, and gradually getting better.

At this time, a voice more enthusiastic than Shufeng suddenly came from the side of the martial arts arena.

"What a coincidence, you are all here!"

It was Bai Jiaci who just came back.

Hong Zhan and Zhan followed the sound, a little surprised.

Since the flower tasting meeting, Bai Jiaci has always been worried.

It has been a long time since he smiled at this time.

"Why are you so happy that you want to talk to us when you come back?"

Hong Fan asked with a smile.

"There is no one to look for, I just happened to come to practice boxing."

Bai Jiaci made a strong argument, covering up the topic.

"At the Hualu shop today, who do you think I saw?"

he asked anxiously.

"That white-haired aunt from the Shen family?"

Hong Fan guessed casually.

Bai Jiaci shook his head.

"Wind Xu?"

Zhan Yuanzi guessed again.

"How could these two people come to buy the flower dew in person, and we will deliver it there..."

Bai Jiaci waved his hands again and again.

"It's the lady Hongli who ordered tea for us that day!"

He revealed the answer with a smile, and said happily.

Then, he noticed that the eyes of the two teammates narrowed slightly.

"Just say it casually, just say it casually..."

Bai Jiaci immediately suppressed his smile, and practiced his fists, only to realize that he couldn't move his legs.

It turned out that the Baihuapo gown on his body hadn't been replaced with a military uniform.

Both Hong and Zhan laughed.

Bai Jiaci blushed, and had no choice but to withdraw his fists in resentment, and escaped from the martial arts arena with a smile.

······
The sun rises and the moon sets, and half a moon flies by in a blink of an eye.

In the 28th year of Zhenghe, the first day of August.

The three heats go east, and the long summer will end.

At noon, the study of Chaori Mansion.

"This plan was drafted by Brother Sheng, and your four uncles added polish."

Hong Pan, who had not been back from Jinhai for a long time, said.

"Of course, you have to see it before deciding."

Across the desk, Hong Fan read carefully without missing a single word.

"It's thorough enough."

After half a cup of tea, he smiled.

"After all, there are only a few hundred people in the clan. After getting along day and night, it is not difficult to judge who is diligent and who is lazy."

"In addition, for those who are going up, since there is no shortage of marrow washing pills, they can be allocated according to needs temporarily."

Hong Fan closed the folder, put it aside, and opened the second wax seal.

"This is an overview of the current situation in the clan."

Hong Pan explained.

"From now on, Jinhai will report to you monthly on finances, personnel, and everyone's progress in martial arts."

"I will also start to arrange the pigeon route between the two cities, and it will be completed before the end of the year."

Hong Fan nodded when he heard this, and saw that there was one more name in the whole item than expected.

"Brother She has entered the Chaotic Realm? When did it happen?"

he asked.

"In July, I took him to meet his future father-in-law, after we decided to marry Yiyue."

Hong Pan replied flatly, unable to hold back the corners of his mouth.

"This is really a joy on top of the joy!"

Hong Fan congratulated, the joy came from the heart.

The Hong family is already one with him.

Whether it is in Xijing or Shenjing in the future, when he needs to build his own team, the children of Jin Haihong's family will be the best arms.

At the end of the second booklet, there is also a rough prediction made by Hong Li——Three years later, the penetration realm in the clan is expected to exceed one hundred, and the Hunran realm can even be doubled.

After reading the two notebooks, Hong Fan remained calm.

Finally, there is a letter signed by six senior members of the Hong family.

There are no fancy words in the letter.

But Hong Fan read the entire text and was finally moved.

This is an authorization letter.

The senior members of the Hong family jointly signed the letter, granting Hong Fan the right to directly mobilize Zhu Yiqi without having to report for approval.
