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

Yin Cheng cleared his throat. "Give me some water to soothe my throat."

"Xiao Anzi," Yin Mo called out.

Xiao Anzi, who was lighting candles, immediately said, "This servant will go right away."

Yin Cheng took a sip of tea and continued, "This bicycle can't completely replace a horse-drawn carriage, and riding it for a long time can damage your health, but it's perfectly adequate for basic transportation."

"Furthermore, it can be modified to allow two or three people to ride together, increasing kinetic energy, and the back seat can be modified to transport goods."

"Rubber tires can also be made. There are many rubber trees in Huaizhou, so we can arrange for people to collect rubber. Oh, by the way, horse-drawn carriages can also use rubber tires, which will greatly stabilize the vehicle and reduce vibrations."

"Of course, I can also build steam-powered cars, but our current production capacity isn't enough."

After listening, Yin Mo looked at his younger brother with a complicated expression.

"Why are you looking at me like that?" Yin Cheng said. "It's kind of creepy."

Yin Mo said, "So you knew so many good things, why didn't you say so before?!"

Are you still hiding it from your brother?

Yin Cheng felt slightly guilty. "I just couldn't remember."

If I hadn't happened to be chatting with my wife about it today, I probably would never have remembered it in my life.

"Can the speed of this bicycle you mentioned be compared to that of a horse-drawn carriage?" Yin Mo asked.

Yin Cheng said, "Then the horse is definitely faster. A typical horse can travel at 30 kilometers per hour, while a bicycle can travel at an average speed of 15 kilometers per hour."

Although Yin Mo didn't quite understand, he quickly grasped the key point: "So, does that mean we still need a horse-drawn carriage for long journeys, but bicycles can be used for short distances?"

"It has to be His Majesty the Emperor. Otherwise, how could I say you're so smart, brother?" Yin Cheng began to shower his brother with compliments. "What have the common people done to deserve such a good emperor?"

"Alright, stop flattering me." Yin Mo thought for a moment and quickly weighed the pros and cons. "These days, a fine horse costs around a hundred taels of silver, making it difficult for ordinary people to travel. If we could build one, it would be a good thing."

"Right? We'll open a bicycle training class and set up a bicycle transportation center. After modifying the bikes into three-wheeled vehicles, each bike can carry about ten people, and we'll charge according to the distance."

Yin Mo tapped his younger brother on the head. "Are you obsessed with money?"

"Yes," Yin Cheng said, "I want to build a family fortune for my precious Pearl so that she won't be easily fooled by that blond guy in the future."

"Oh, by the way, speaking of pearls, I've come up with a few names, take a look." Yin Mo asked Xiao Anzi to go to the Imperial Study to get the booklet, while Yin Cheng was not in a hurry and sat cross-legged.

"The modified tricycles can carry up to 600 jin (300 kg), which is quite good for transporting goods," Yin Cheng said. "It's much more convenient than carrying things by hand."

Yin Mo said, "Okay, I'll have someone from the Ministry of Works come and take a look tomorrow, and then we'll try to build one."

The two brothers chatted casually, and soon Xiao Anzi brought over the roster.

Yin Cheng opened it and saw, "Mi Zhang, Yining, Huayu, Zhiwei... it has to be my brother. It's only been a short time since he was born."

And each of them looks very cultured and speaks very well; no wonder they are emperors! Their literary cultivation is extremely high!

He tucked the booklet into his pocket. "Alright, I'll go back and ask Niannian what she thinks. You shouldn't be idle either; quickly send someone to fill the vacancies in the Ministry of Rites so that I, Zhenzhu, can get my salary back as soon as possible."

Yin Mo: "Sometimes I really want you to get lost faster."

"Don't worry about it, I'm leaving now," Yin Cheng said. "You can handle the bicycle yourself. Call me when it's finished, and I'll teach you how to ride it. Oh, and remember to send someone to Huaizhou to collect rubber trees. I've also drawn a picture of what those trees look like."

Yin Cheng's drawing was extremely detailed; he even drew out how to collect the adhesive.

"Get lost." Yin Mo was exhausted. This silly younger brother.

After Yin Cheng returned home, he handed the booklet to his wife. When he came out after taking a shower, his wife looked conflicted.

Yin Cheng burrowed into bed, embracing his wife. "So, which one do you think is better?"

Lin Nian thought for a moment, "This one is good, but this one is also okay." He was troubled, "It's so hard to choose, it feels like every one is suitable for pearls."

"Then let Pearl choose for herself."

Lin Nian asked in confusion, "How do I choose the pearls?"

"That's easy, just draw lots."

The next day, as soon as Pearl woke up, he felt someone grab his hand and stuff it into the box.

"Pearl, grab one yourself."

Pearl vaguely heard her father's voice, and without caring what it was, she grabbed one at random.

Yin Cheng and Lin Nian exchanged a glance.

Lin Nian carefully opened the note, and saw the words "Zhiwei" written on it.

"Yin Zhiwei, that sounds nice!" Lin Nian kissed the sleepy little round face. "Baby, you have a name now. From now on, you'll be called Yin Zhiwei."

Pearl scratched her face, not understanding why, but she just laughed along.

Lin Nianhuan happily ran to find the little servant and asked him to deliver a message back to Ye Qingyu.

-----------------

On the day Yan Ru's delegation arrived in the capital, Old Man Xue appeared before Yin Cheng for the first time ever.

"Hey kid, got a moment?"

Yin Cheng looked around, pointed to himself, and said, "You're asking me?"

"Nonsense." Old Xue rolled his eyes. "Who else could it be but you?"

"What's up?" Yin Cheng asked. "I still have to keep an eye on the Yanru delegation. If you need anything, just say so. I'm quite busy."

Old Xue said, "I lied to you before."

"Oh," Yin Cheng said indifferently, "If you're going to apologize, hurry up and do it."

Old Man Xue: "..."

Old Xue cleared his throat. "I lied to you before, saying I came to seek refuge with you, but actually I came to ask for your help."

"What kind of help do you need?"

"I need you to help me find someone."

Yin Cheng said, "Okay, who should we look for?"

"Chu Ningyun".

Yin Cheng's eyes darkened, and his voice unconsciously turned cold. "What do you want with him?"

"Actually, I used to be a member of Tianji Manor too." Old Xue scratched his head somewhat embarrassedly when talking about the past, after all, Tianji Manor and he were both in a bad situation now.

Yin Cheng said, "After I regained my memories, I discovered that you were also using the Heavenly Extreme Heart Sutra, which made me guess."

Those who know both the Heavenly Extreme Heart Sutra and the Flowing Shadow Blade must be from the same sect.

"After you left, I went back to Tianji Manor, but there was no one there," Old Man Xue said. "The old Taoist priest in the back mountain was also nowhere to be found. I also discovered Ningyun's grave. But for some reason, it was empty. He must not be dead."

Guangjian is gone? Could it be that he went down the mountain to find his master? Yin Cheng lowered his eyes, gathering his thoughts. "What does his life or death have to do with you?"

"I know you're Hemu's apprentice, but for the sake of Ningyun being your master's father, please help me find him," Old Man Xue said. "I just want to find him."

Yin Cheng twisted his neck, his bones making a "crackling" sound. "I am not He Mu's disciple. My only master is Chu Ningyun."
