"Squeak~!"

At three quarters of the child's hour, the moon is on the treetops. The door of the main wing in the west courtyard of Yong'an Hou's Mansion in Lantian County was opened from the outside, and a tall figure took this opportunity to walk in sideways.

"Xiang Gong~! Why did you only come back now~?"

Inside the house, a woman wearing a cape walked over quickly. After seeing the man who had just entered the door, the woman was both surprised and complained a little.

"Uh... madam, you haven't slept yet!"

The black figure crouched out and turned around to look like a woman and laughed dryly.

"The concubine can't sleep alone, she has been waiting for her husband to come back!"

The woman responded, and then asked suspiciously: "Xianggong, isn't today the day when the Tianji Brigade returns? Where have you been?"

"Alas! Forget it! My husband was kidnapped by a lunatic for an entire afternoon and a night!"

The man waved his hand, his tone full of helplessness.

That's right, the man is Li Zexuan, and the woman is Han Yuxi who hasn't fallen asleep.

By the way, Li Zexuan just came back from the workshop outside Lantian County!

"Crazy? Where's the madman? What are you talking about, Master?"

Han Yuxi heard the words, her face was full of doubts, she blinked her eyes and said puzzled.

"Hey! Who else could it be? Qingque! This little fat man is so persistent that he is no different from a lunatic!"

Li Zexuan waved his hand and sighed.

Thinking of what happened in the afternoon, Li Zexuan suddenly felt a toothache!

It was said that Li Zexuan planned to leave after drawing the steam engine drawings for Li Tai in the workshop in the afternoon, but Li Tai stopped him and insisted on pestering him to ask about the principles of telephone modulation and noise reduction. and method, after all, he said at the beginning that he would give Li Tai a general plan or idea before leaving.

Li Zexuan didn't expect the little fat man to have such a good memory. In desperation, he wanted to give Li Tai a few typical noise reduction filter circuit and modulation and demodulation circuit diagrams and sent Li Tai away. Who knew that after the little fat man got the circuit diagram? Not reconciled to this, still ask questions and ask questions!

Perhaps it was because he thought that it would be difficult to ask Li Tai questions after he entered the barracks, so Li Tai could not wait to ask all the questions in his life today! In the end, Li Zexuan even explained to him the basic knowledge of Euler's formula, Fourier transform, Fourier series, frequency domain, time domain and other related aspects for several hours!

This lecture went directly from the afternoon to the middle of the night. God knows how collapsed Li Zexuan's explanation is. He has never answered so many questions from others. To a certain extent, Li Tai has made him an "exception"!

The reason why he is so "fighting" is that firstly, he has high hopes for Li Tai; secondly, he vaguely understands that Li Tai is using this method to express his reluctance to go to the military camp; thirdly, these When it comes to professional knowledge in advanced mathematics and signal processing, although Li Tai can't understand it now, it may not be a bad thing to let him be familiar with it in advance and have a general concept in his mind!

However, this made Li Zexuan exhausted. As a human being, he has spoken the most today, and his mouth is still dry.

"Don't talk about that! Madam, please help my husband pour some water, I'm dying of thirst!"

Without answering Han Yuxi's question directly, Li Zexuan felt his mouth dry again, and hurriedly said.

"Ah? Oh! Good! Mrs. wait a moment, I will pour water for you!"

Han Yuxi was stunned for a while, and quickly responded after reacting.

"Grumble~!"

Taking the cup of warm water handed over by Han Yuxi, Li Zexuan raised his head without image and poured it directly into his mouth, drinking a large cup of warm water "gulugulu".

"Master, you just said that His Royal Highness King Wei is like a lunatic, what's the matter~?"

Seeing that Li Zexuan had finished drinking water and was lying lazily on the Taishi chair, Han Yuxi sat beside Li Zexuan and asked softly.

"Oh, nothing! Isn't this the workshop that built the telephone and the telegraph relay station. The kid encountered some problems and finally caught me. He still has to get to the bottom of it~?"

Li Zexuan pouted and said angrily.

"Puchi~!"

Hearing what Li Zexuan said was interesting, Han Yuxi couldn't help laughing "Puchi" and said, "You are too, Xianggong, you didn't go to the workshop a few times for a whole month, Qing Que was expensive as a prince, but you used it as a coolie, all day long. I worked hard for you, if His Majesty knew about it, I would definitely not forgive you!"

Li Zexuan sat up straight when he heard the words, and he retorted: "Miss, it's not right for you to say that! The child of Qingque is chasing the truth, and the hard work is a little harder, but when he truly succeeds, he will It will be recorded in the annals of history, how can this be regarded as being used by me as a coolie~?”

Although, Li Tai is indeed living like a coolie now, but Li Zexuan is resolutely unwilling to admit that he "illegally" used "child labor"!

Han Yu glared at Li Zexuan, but didn't pierce her husband's strong words. Suddenly, she turned her eyes and said in a low voice: "Master, you are getting bigger and bigger now, and the previous Xuanjia army joined the army, that's all, this time Your Majesty And you are named Qingzhou prefect, do you think His Majesty will send you to Qingzhou to take office someday~?"

Li Zexuan's face was slightly startled, and he couldn't help but look at Han Yuxi. From the latter's eyes, he could see the kind of dazedness about the future. Also, although Han Yuxi's body was flowing with the blood of the former noble Han Jihu family

, But he lived in poverty since he was a child, but because he married Li Zexuan, he became a phoenix. Now Li Zexuan does not say that he is a powerful person, but he is also a top figure in the ruling clique of the Tang Dynasty. This is a person Han Yuxi has never met. At the level, of course, she will be dazed!

Seeing this, Li Zexuan couldn't help his heart soften. He stood up and stood in front of Han Yuxi. He gently stroked the long hair with his hands and comforted softly:

"Don't be afraid, madam, no matter where you are, my husband can support you and a warm home!"

"Uh-huh!"

Han Yuxi couldn't help hugging Li Zexuan's waist tightly, buried her head on Li Zexuan's stomach, and hummed: "I believe in my husband, where there is a husband, there will be a home~!"

In the past month or so, Li Zexuan has been very busy, and he has been running around outside all day. It is rare for the couple to have such a quiet and peaceful embrace, so both of them cherish it very much, and no one wants to break this peace!

I don't know how long it took, Han Yuxi raised her face and whispered: "Xiang Gong, it's late at night! Let's rest early! There will be an entrance exam for the academy tomorrow morning!"

"Um!"

Li Zexuan responded, suddenly remembered something, hesitated for a moment, and said, "Ma'am, in two days, when the academy's affairs are over, my husband will have to report to the Xuanjia army camp! This family is hard work. is you!"

"... so fast?"

Even though she had expected such a day in her heart, Han Yuxi did not expect this day to come so soon, and her face turned pale.

Li Zexuan hurriedly said, "Don't worry, madam, my husband is now a marquis of Tang Dynasty, and even a provincial governor. Even if he is in the military camp, he will not suffer much, and maybe he will gain a little weight after he comes out of the military camp. Jin! When the time comes, lady, don't dislike it~!"

Han Yuxi got up quickly and retorted: "Xiang Gong, you are talking nonsense! No matter what you become, the concubine will not dislike you! The concubine is just worried..."

"What are you worried about~?"

"The concubine is worried that one day in the future, the Great Tang and the Turks will go to war, and His Majesty will send you to the front line..."

"Haha! Silly girl!"

Hearing this, Li Zexuan couldn't help but flicked Han Yuxi's forehead and said with a smile: "Even if Your Majesty really sends her husband to the front line, there is nothing to worry about! Madam, you don't know how powerful your husband is, this world can hurt you. The husband has no more than five people. If you are really in danger, just run for your husband! With such a delicate beauty as a lady, I can’t bear to die on the battlefield~!”

Li Zexuan said it easily, but Han Yuxi understood that Li Zexuan said this on purpose to comfort her. After a moment of silence, she looked at Li Zexuan with tears in her eyes and said:

"Concubine knows that Xianggong has the family and the world in his heart, and he also knows that if there is an edict from the sage, Xianggong will definitely go to the front line without hesitation, Xianggong rest assured, concubine will not be a stumbling block for you, as long as it is Xianggong's decision, concubine will Support, but I beg Xianggong to think of his concubine, his parents, Laner, and this family when he is at a critical juncture!"

"Miss~!"

Hearing this, Li Zexuan was greatly touched. He stretched out his hands and hugged Han Yuxi tightly. .

It is indeed the greatest blessing in his life to meet such a well-informed and understanding daughter-in-law!
