After Liang Xiao was appointed as a marquis, the Liang family moved to the relatives in Chang'an City to live. Maoling's house was given to the Tu family, and there was no residence in Maoling County. There were houses in the farm. They were originally for the slaves who farmed, but most families built them relatively simple. However, Liang Xiao always cared for his servants and was willing to spend money. The construction was pretty good. Later, he was determined to grow vegetables and expanded them. Now Liu Ling is here to live and clean up, which is quite acceptable.

It was the slack season that Liu Ling asked Tu Tian to find some servants, and Deng Guobin commanded him to build a laboratory according to Liang Xiao's method in Bailu Monastery. When the house was built, the glazed glass from Huainan was also transported and glass windows were installed. The sun was shining outside the house and the bright inside the house was visible. Even Liu Ling was very excited when he saw it.

Everything was ready, Deng Guobin and others started working again, focusing on creating ship models and conducting experiments.

Liu Ling had originally studied "Geometry Originals". Now that he had a lot of time, he picked up "Geometry Originals" again and thought about it carefully. He married Liang Xiao for several months. Although he had been together for a few months, Liang Xiao still used his time as much as possible to answer many questions from Liu Ling. He was originally a little concealed, and sometimes he had to use Dongfang Shuo as a cover. Now that the two have become one, he didn't care and wanted to tell Liu Ling everything he knew.

Liu Ling's attainments in this area have far exceeded ordinary people. Deng Guobin has a strong practical ability to do things, but in terms of mathematical deduction, Liu Ling has obvious advantages. They each showed their strengths and cooperated with each other, and soon had a deeper understanding of shipbuilding, and accumulated a lot of tricks that seemed insignificant, but actually condensed a lot of hard work. Just various maps and materials filled half of the bookshelf.

Liu Ling's life was fulfilling and regular. He either leaned against the window to read or took a walk in the manor. Except for occasionally going to the vegetable fields to check out, he basically didn't go out of the gate, and hid in the suburbs of Chang'an like a hermit.

It was not until one day when a distinguished guest came to visit that her tranquility broke.

When Princess Guantao appeared at the door, Liu Ling blinked and showed a relieved smile, then he greeted him with a spring breeze on his face and bowed to him.

"Master, why are you here? If you have something to do, just say hello and I will visit you myself. How can you make you tired?"

Princess Guantao waved her hand with a smile. "Okay, don't coax me anymore. If I don't come, will you see me?" She held Liu Ling's hand affectionately, and asked Liu Ling's recent situation with concern. She also said some gossips between women, both like friends in the boudoir whom I haven't seen for a long time, and without losing the kindness of the elders.

Liu Ling accompanied her into the house and was about to meet her in the lobby. Princess Guantao stopped and turned to look at the closed West Cross-Bedroom.

"You are hiding behind closed doors and hiding here. What kind of knowledge are you doing? Can you take me to visit?"

"The Grand Lord has orders, how dare you not obey?" Liu Ling smiled and said half-jokingly: "But when did the Grand Lord be interested in these tricks?" As he said, he ordered people to open the door of the Xiquyuan and led Princess Guantao to walk over.

"Before you and your wife are attracting the trend, now talking about literature and reasoning is the most popular elegant thing in Chang'an City. Men are certainly happy about it, but when women meet, they don't talk about the recent new discoveries, they also feel a little out of date. But I am old and lazy, and I can't compare to those young people. Without your help, I am powerless. Now, I came to you here to get the scriptures today."

"Gee" Liu Ling raised his sleeves, covered his lips and smiled, and said a few humility. She led Princess Guantao into the model production room and asked Deng Guobin to take out the prepared ship model for Princess Guantao to appreciate.

Princess Guantao was very surprised to see the exquisite and realistic ship model. She stretched out her fingers with excellent care, picked up a thin piece of wood as thin as a toothpick on the table, and looked at the model, and couldn't believe her eyes. "Are these ship models assembled with such wood chips?"

"Yes, every part is made strictly in accordance with the requirements, and no mistake can be tolerated. The so-called slight difference or a thousand miles of loss. Even if the error is the same as the hair, it may cause the installation error if it is expanded."

"Hair?" Dong Yan, who was accompanying Princess Guantao, was shocked. He rolled up a strand of hair on his temples with his fingers and looked at it, with a look of suspicion in his eyes. "How big can a hair have?"

"It's not just a hair, even half a hair is not good." Deng Guobin asked Liu Ling for instructions, turned around and took out an exquisite wooden box and opened it, took out a caliper from it, and held it carefully in his hand. "Guobin is brave enough to ask the Lord to give you a black hair."

Princess Guantao was puzzled, but she lowered her head with great enthusiasm and asked Dong Yan to pull a hair from her head and hand it over to Deng Guobin.

Deng Guobin asked Dong Yan for a few hairs, and tested them one by one with Princess Guan Tao's hair, then put them on the table, turned around, and asked Dong Yan to change the positions of these hairs. Dong Yan understood what he meant and immediately changed them. He stared at Deng Guobin intently, wanting to see if Deng Guobin could measure the difference between these hairs. One hair was already thin enough, could he measure the difference between two hairs?

This is simply incredible.

Deng Guobin once again measured the diameter of the hairs, and then picked up one with confidence. "This is the big master's black hair."

Princess Guantao exclaimed: "How is this possible?"

Deng Guobin put away the caliper and smiled proudly. Liu Ling took the wooden box from Deng Guobin and held it in front of Princess Guantao. "Master, this ruler is designed by my husband. I also asked a craftsman to carefully make it. You can tell one-third of the hair. Dong Jun was young and his hair was thick, but he could still tell it."

"Is that right?" Princess Guantao took the ruler, held it in front of her eyes and looked carefully, and exclaimed repeatedly. "It's simply exquisite and unheard of. I've never heard of such an accurate ruler."

"If you want to do a good job, you must first sharpen your weapons. This is their weapon, so you will naturally never get tired of it." Liu Ling took the caliper from Princess Tao of Guan and handed it to Deng Guobin, and said, "The Lord is not an outsider, and I am not afraid that you will laugh at me for being shallow. We are still developing more precise rulers. At that time, we can not only distinguish the thickness of the two hairs, but also accurately measure the size of the hair."

"Take it seriously?" Princess Guantao was skeptical. "When will it be made? I want to take a look."

Liu Ling smiled and said, "It's not difficult. I have invested nearly a hundred gold coins and haven't been able to create them yet. When they are made, I will definitely ask the Grand Lord to appreciate them."

"Spend a hundred gold to build a ruler?" Princess Guantao smiled and shook her head. "Master Weng, you are so rich."

"Tailor, although my Liang family is not as rich as the Tailor, he is favored by His Majesty and has little wealth. In addition to food and clothing, you have to do some serious business. Spend a hundred gold to make a ruler. It seems a waste, but if you can find something, it will be comparable to a hundred gold? Just like the two wise men in your family, if they hadn't spent a thousand gold to buy iron smelting methods, how could they make a fortune every day?"

When talking about the Chen brothers making swords, Princess Guantao was in a good mood. Brother Chen Xu created a top-notch sword and presented it to the emperor. Not only did he gain the common sense of the emperor, he was able to take up a free position in Shangfang and build swords for the emperor. The Chen family's swords were also treasures that the young man in the capital spared no expense to buy. The Chen family not only earned the money back, but also had a lot of money to win, which was a win for both fame and fortune.

Using this example as a metaphor, the persuasion will naturally increase greatly.

Liu Ling took Princess Guantao to visit. Princess Guantao opened her eyes and praised her endlessly. The two returned to the hall and took a seat with the guests. Liu Ling ordered someone to take some radishes that had just been pulled out of the field, cut them into thin slices, and brought them up, and asked Princess Guantao to taste them.

Princess Guantao said for a long time and felt dry mouth. After tasting a piece, she suddenly felt salivation and smelly on her teeth and cheeks. She couldn't help but eat a few pieces.

"What's this?"

"This is the fruit and vegetable brought back by my husband from the Western Regions, called radish." Liu Ling smiled and said, "The first time Taizhu eats it, he can't eat too much. Some people are not used to it, and their stomachs will feel uncomfortable. If they are used to it, this is a good thing."

After hearing what Liu Ling said, Princess Guantao didn't dare to eat too much, but was envious of Liu Ling and joked: "No wonder you don't want to go back to the city. Living here is indeed quiet and comfortable. If you have time, I'll stay for a few days, which is feasible?"

Liu Ling laughed so hard, but shook his head. "The Lord misunderstood. I live here, not entirely because I live comfortably. The things you just saw were originally my husband's responsibilities. He was ordered to go to Nanyue, but he didn't care about it for a while, so I had to reluctantly take it and avoid delaying the main business. If it weren't for this, how could I, a very lively person, stay here?"

Princess Guantao put away her smile. When Liang Xiao went to the South Yue mission, she heard Dou Ying say that, and knew the danger. When Liu Ling said this, she was not able to answer for a moment. She thought for a while and said, "The Chanjun Hou was on the South Yue mission, but the Yuzhang Shipyard did not stop. His Majesty arranged for someone to be responsible again. Why do you have to work so hard?"

Liu Ling chuckled: "Not everyone can do well in the shipyard. In front of the Tailor, I am not afraid of you making jokes. In my opinion, if you supervise the construction of warships, no one can catch up with my husband in the world. Even I am afraid I can't get enough of it. I can only fly first, spend more time, and hope not to fall behind too much."

Princess Guantao's eyes flashed slightly. "Champion Hou has indeed seen people, but no one else can do this in charge of building warships?"

Liu Ling did not argue. She thought for a while and smiled slightly. "Let's do it, when you leave later, pick a ship model and take it away. Then I will make the same ship model, and all the parts can be exchanged with the one you took. If you can also build such a ship model within three months, I will lose your wealth, what if?"

Princess Guantao was a little hesitant.

Liu Ling raised his eyebrows. "Does the Grand Lord feel sorry for the daughter, or do you have no confidence?"

After being agitated by Liu Ling, Princess Guantao also became interested. "If I ask for help, it wouldn't be considered a violation, right?"

"Who can you ask for help?" Liu Ling was full of confidence. "Even if you ask in front of the queen, I have enough confidence to beat you."

Princess Guantao laughed and clapped her hands. "Okay, one word is certain."

Princess Guantao returned home and immediately invited Dou Ying to tell her bet with Liu Ling.

Dou Ying looked around the ship model and then, and finally shook her head. "Master, you are afraid you will lose this bet."

"You don't have confidence in me either?" Princess Guantao was dissatisfied. "Even if my Chen family can't find such a skilled craftsman, isn't there in the palace?"

Dou Ying glanced at her and laughed silently. "Do you think Liu Ling is betting with you? She is betting with the emperor."

Princess Guantao asked inexplicably. Dou Ying explained: "Have you read "Shanmu" in "Zhuangzi"?"

Princess Guantao nodded. Although she was not good at learning, when the Empress Dowager was alive, she asked them to read Taoist books. "Zhuangzi" was naturally read, and "Shanmu" also had some impressions.

"Then do you think Liang Xiao is a useful geese that is alive or a useful tree that is dead?"

This time, Princess Guantao did not hesitate. "Of course it is useful to live, what else can it be if you die? Oh, by the way." She suddenly realized. "Liu Ling wanted to tell the emperor that although Liang Xiao was unruly, he had talents that were difficult for ordinary people to reach. He was useful to the emperor, so he could not die."

Dou Ying laughed loudly and then shook his head again. "A scholar of the King of Huainan gave birth to a good daughter, which is really enviable." He thought for a while and said, "However, the smartest one is Liang Xiao. This kid is knowledgeable. No wonder he insisted on marrying Liu Ling as his wife despite the taboos of the emperor. This is a true virtuous supporter. With Liu Ling in Chang'an, even if he moved to Tianya, he would not become a fish. This kid is knowledgeable."

Seeing Dou Ying, who had always been conceited, praise Liang Xiao and Liu Ling, Princess Guantao was so amused. "This sloppy woman is worried about why her husband doesn't say anything directly. I just let the queen ask His Majesty, but after such a big turn, I even misled my daughter. It's really annoying."

Dou Ying laughed even happier when she heard this.

The two discussed again. Princess Guantao sent the ship model into the palace according to Dou Ying's teachings and handed it over to Queen Chen. Queen Chen understood it and found an opportunity to ask for it in front of the emperor. The emperor's mind was obviously much more sensitive than Princess Guantao. As soon as he saw the ship model, he understood what Liu Ling meant.

However, he said nothing and smiled as if nothing had happened: "Okay, I'll take this bet for my aunt. If I lose, I'll pay the daughter. If I win, hehe..." He chuckled twice, picked up the boat model, and looked at it carefully. "I'm not in a hurry. When Liang Xiao comes back, he will send the daughter to the palace in person, and then let him build a boat for me for the rest of my life."

Queen Chen smiled with a funny smile and said, "That's right, only a clever knight like Your Majesty can subdue a wild horse like Liang Xiao, use a little trick, and let him obey and serve His Majesty closely."

The emperor bent his lips and laughed softly, "Is it actually very simple to train a horse? It only takes whip, whip, and knife. At first, whip the body; if you don't accept it, you will slap the bone; if you don't accept it, you will break the head. If you don't accept it, you will not accept it. In these three steps, what kind of fierce horse will not accept it?"

Queen Chen shivered, and a ray of anxiety flashed in her eyes.-
