After marrying the fierce god, her handsome young husband was pampered to the extreme.

Lin Nian looked at the man in surprise, "When did you bring Xiao Zhan out with you?"

Yin Cheng said, "I just grabbed it."

He carefully scraped off the frost from the wall with his dagger, and soon the small cup was filled with a thick layer of frost.

"Husband, what is this?"

Yin Cheng said, "Saltpeter."

Lin Nian asked, puzzled, "What are you going to do?"

"Make ice." Yin Cheng finished scraping off the frost. "Niannian, give me your handkerchief."

Lin Nian handed over the handkerchief.

Yin Cheng carefully wrapped the small cup to ensure that the saltpeter wouldn't spill out, then put his arm around Lin Nian's waist and flew back to the mansion.

Lin Nian thought to herself: This feels right, this is how I've always flown before!

Out of sheer curiosity about how to make ice from this white frost, Lin Nian eagerly pulled the man aside and asked him to demonstrate.

Yin Cheng demonstrated the ice-making process to his wife, captivating Lin Nian so much that she didn't even blink.

"Is this all you need?"

Yin Cheng nodded, "I'll come back tomorrow."

Lin Nian nodded, "Mm!"

Yin Cheng was completely captivated by his wife's adoring gaze, and the next day when he went out to train his troops, he was practically flying.

When Lin Nian woke up the next day, she couldn't wait to go and see, and sure enough, she saw that the water in the small basin had frozen into ice.

According to the man's instructions before he left, only the ice in the small basin was edible.

Lin Nian was cautious and instructed the servants to prevent them from accidentally eating ice that was not safe to eat.

That night, Lin Nian took the man to find saltpeter, and the edible ice she made was also sent to the shop.

The dessert shop's business boomed again, and Lin Nian was so happy that she arranged a sweet and sour feast for the man.

Throughout the entire Northern Territory, almost no one knew that His Highness Prince Cheng enjoyed sweet and sour dishes.

Even Hua Yue didn't know, let alone the cooks in the manor.

Lin Nian thought that the man was just embarrassed, after all, a grown man who liked sweet and sour dishes would be ridiculed if he said it out loud.

As a husband, Lin Nian felt she had to protect her husband's reputation.

So he deliberately spread the word that Prince Cheng had a craving for sweet and sour dishes, and Prince Cheng had no choice but to accompany his husband.

Later that night, when Lin Nian was going to sleep, she suddenly thought of this and casually asked the man about it.

Unexpectedly, Yin Cheng said it was because the sweet and sour sauce made by the chef here was not good.

Lin Nian thought and thought, racking her brains, but she couldn't figure out the reason.

In order to make sure the man could eat the dishes she liked, Lin Nian would cook every few days, which startled the cooks in the mansion, who thought it was because they hadn't cooked well. They would go over the cooking process several times before going to bed at night.

The weather was hot, and there was plenty of ice in the mansion to cool people down. Lin Nian thought about writing a letter to her third brother.

Not knowing how long it would take for the messenger to deliver the letter, Lin Nian wrote down the method of making ice with saltpeter in the letter, hoping that her third brother could also achieve the freedom to use ice before the summer heat ended.

Since I've already written to my third brother, I can't forget to write to my uncle, my eldest and second brothers, and I'll also write to my fourth and fifth brothers in the southwest.

When Yin Cheng saw the letter his wife had written, he was momentarily at a loss.

This thick stack of family letters, if you know it's a letter, you might mistake it for a biography.

The imperial messengers usually began delivering letters in the middle of each month. In the past, imperial messengers only escorted official documents such as memorials to the emperor for officials in various regions.

Later, after Yin Mo ascended the throne, he specifically divided messengers into two categories: official messengers were responsible for receiving letters from officials in various regions, while ordinary messengers were responsible for receiving letters from the common people.

Charging fees based on the length of the journey generated hundreds of thousands of taels of silver for the imperial court each year, greatly relieving the pressure on the national treasury.

Yin Cheng, who proposed establishing mail transfer hubs in various counties and prefectures, remained perfectly hidden behind his brother.

Lin Nian specifically asked Wang Zhao if he wanted to send a letter home.

Wang Zhao said there was nothing to say, but that night after returning to his room, he lit a lamp and wrote three full pages.

The next day at breakfast, Wang Zhao handed his letter home to Lin Nian and asked Lin Nian to send it to the post station for him.

Lin Nian took the letter and replied, "Okay."

"I need to go to Song County," Wang Zhao suddenly said. "I can help you send a message to Third Brother; it'll definitely be faster than a messenger."

Lin San's transfer order was issued in Song County.

What are you going to Song County for?

Wang Zhao said he would accompany the escort agency on a delivery mission, just to familiarize himself with the process beforehand.

Lin Nian then learned that the escort agency next to the dessert shop was only a short distance away in Song County, which was under the jurisdiction of Yuezhou. It was only a few dozen miles away.

I don't know how Wang Zhao managed to build such a good relationship with these people during this time, because they were actually willing to take him on a delivery mission.

Lin Nian was completely baffled and wanted to ask Wang Zhao, but he brushed her off with a laugh.

Lin Nian said seriously, "If you don't explain yourself clearly, I won't agree to let you go."

Wang Zhao pouted, "I told them I was going to find my long-lost brother."

Lin Nian: "..."

"I disagree." Lin Nian was practically worried sick about this young man. "You've only known them for a short time. What if they're bad people? What if they sell you off somewhere? Where will I find you then?!"

"Oh dear!" Wang Zhao said, "The security escort agencies are all doing legitimate business, where would any bad people come from?"

"Let the child go if they want to," Yin Cheng said, placing a steamed bun on his wife's plate. "It's only a few dozen miles away; if they go in the morning, they can get there by evening."

Lin Nian exclaimed in surprise, "So close?" Then wouldn't it be possible to invite Third Brother over to celebrate holidays together?

"It's shorter by water," Yin Cheng said. "There's the Wuding River down the mountain. During the high-water season, you can take a boat there and get there in half a day."

Wang Zhao also said, "Yes, yes, it's so close, what could possibly happen?"

"But my third brother parted ways with us so early, I thought it would be at least several days' journey."

"He needs to go to the prefectural city to report to the prefect first," Yin Cheng said. "Our brother personally issued the transfer order, so he must have had his own motives."

Lin Nian wanted to say something more, but suddenly remembered Wang Zhao, "In short, I don't agree with Xiao Zhao going to the escort agency by herself."

"Who said he was alone?" Yin Cheng whispered to his wife, "Don't worry, I'll send bodyguards to follow him. Nothing will happen."

Before Lin Nian could say anything more, Yin Cheng added, "Wang Zhao gets tired from kneading sugar powder every day, what's wrong with him going out to have some fun?"

Wang Zhao was surprised that Yin Cheng was on his side, and immediately offered his sincerest blessings, "Prince Cheng, look what an exceptionally good man you've married!"

Yin Cheng: "..." There's no need to praise him like that.

"Let's vote," Yin Cheng said. "I support it."

Hua Yue raised her chubby little hand, "I support it too. Brother Wang Zhao works very hard at the dessert shop every night."

Xiao Fu said timidly, "I...I support Wang Jun."

Hua Yue glanced at Lin Nian's expression, and just as she was about to back out, she looked at Wang Zhao again.

His face scrunched up in frustration.

Lin Nian sighed, "Alright, I agree, but you must bring the garrison soldiers with you."

Wang Zhao was about to laugh when he heard that the guards were accompanying them, and his not-yet-fully-bared teeth immediately disappeared. "Ah, no way! Who brings guards on a镖局 (bodyguard agency) escort mission?"
