At dusk, the sun sets like fire.

The colorful glow shines through the window and falls on the huge sand table, quiet and peaceful.

Qin Huaidao, who had been busy all day, finally straightened his waist, looking at the barely usable sand table, he was extremely comfortable, although the roads, rivers, forests, etc. could not be directly expressed from the color of the materials, but they also looked good.

This sand table fell in the eyes of Li Erhe and a minister, but it was like a miracle, intuitive and clear mountains and rivers, roads, post stations, border passes, rivers, cities, etc., it is simply a miniature version of the ancient road of Fu Luo, clear at a glance, lifelike.

Li Jing said excitedly: "Shengshang, this method can be called a miracle, if it is applied to the military, it will get twice the result with half the effort, and the minister implores all armies to make a sand table in the jurisdiction, and the imperial court will make a sand table in the territory of the Tang Dynasty, so as to facilitate the Holy Lord to guide the country and rule the four seas." ”

"The ministers seconded it!" Others have agreed, with the sand table, many things are much easier to deal with, only need a finger, at a glance, and clearly.

Li Er also saw the important role of the sand table, which is much more convenient than the map, but he also knows that it must be made accurately, once it goes wrong, it will also cause endless troubles, and accuracy means investing a lot of manpower and material resources to investigate and get back detailed information, but compared with the benefits, this investment is nothing.

Once you do a good job, you can look at yourself every day, and the mood is beautiful to think about.

One by one, thoughts flashed, and Li Er said: "Yes, but this sand table is limited to the use of the military department, and it must not be spread outside, otherwise it will be punished for treason." ”

"The ministers obey." Everyone agreed, the sand table is too important, once it is learned by the enemy, there will be endless troubles.

Li Er looked at Qin Huaidao, the appreciation in his eyes became stronger and stronger, and when he thought that the other party was about to become his son-in-law, he was in a better mood, and said with a smile: "Huaidao, you have once again given me a surprise, this sand table is comparable to an army of 100,000, say, what reward do you want." ”

Meritorious service must be rewarded, this is the rule of the imperial court.

But Qin Huaidao knew that he couldn't accept it at will, the title was already the prince of the country, and then he was the prince, it was impossible to give, and he couldn't accept it, otherwise he would die faster, as for the official position, it was already a three-grade Shangshu, and then it was also a suspicion of high merit and shocking the lord, but the benefits of getting it should not be in vain, so he immediately said: "Shengshang, the minister is only interested in silver and beauties, so it is better to appreciate them all." ”

"Hahaha!" The ministers smiled good-naturedly.

Li Jing and Fang Xuanling secretly breathed a sigh of relief, just now they were really afraid that Qin Huaidao would take the opportunity to ask for it and fall into hidden dangers.

Li Er saw that Qin Huaidao was defiling himself, and his mood was getting better and better, where to find this kind of loyal, talented, and knowledgeable courtiers who knew how to advance and retreat? Said with a smile: "You are the son-in-law I selected, what kind of system does it become to appreciate beautiful women, as for the silver, I am also lacking, I heard the pharmacist say that you made a kind of tea is very good, since you like tea, I will reward you with a tea mountain, do you remember the tea house in Jingyang County?" ”

"Remember, the minister was almost ambushed by the people inside." Qin Huaidao hurriedly replied that when he escorted the coal convoy back, he was ambushed and tracked to an ownerless tea house, and found that the mastermind was the person sent by the prince to the side of King Wei, trying to blame King Wei, and also extorted more than 1,000 acres of fertile land from the eldest grandson Wuji.

How could Qin Huaidao forget this account?!

Li Er said with a smile: "I am still investigating the ambush, and I will definitely give you a satisfactory answer, and that tea mountain will be rewarded to you in the future." ”

"Thank you." Qin Huaidao hurriedly thanked him, don't do such a good thing in vain, the mountains and rivers are beautiful, the environment is beautiful, and it is not far from Chang'an, it is completely possible to make a farm for future vacations, the tea tree area is large enough, and you don't have to worry about not being able to buy tea in the future.

"Okay, let's talk about the road construction, Zhou Zhi County wrote a letter to ask for compensation for the local people, you know about this matter, right?" Li Er asked, the smile on his face gradually disappearing.

The ministers also looked at Qin Huaidao, and Fang Xuanling asked bluntly: "Huaidao, Zhou Zhi's county order is reasonable to petition for the people, and the court is also in trouble, do you have a way to resolve it?" ”

"Back to the saint, Fang Xianggong, the minister saw the Wei County Order when he inspected the terrain and knew about it." Qin Huaidao said and found a long stick, pointed to the Heihe River on the sand table and continued: "Holy Lord, please look, my lords, the minister suggested that along the Heihe River to the south, build a new road to Luogu Pass, bypassing Zhouzhi County. ”

Bypass it, and all problems will be solved!

Everyone's eyes lit up, and they all looked at the location of the Heihe River on the sand table, but the terrain in the middle of the Heihe River is steep, the mountains are high and the forests are dense, how easy it is to build the road, and they didn't open their mouths for a while, Li Er was bold and bold, and he did not object to rebuilding a road, and after thinking for a while, he asked: "This method is feasible, but the construction period is increasing, and the difficulty is higher, how sure are you sure?" ”

"Back to the saint, the minister has conducted field investigations along the Heihe River, and he is completely sure."

"Oh, what about the duration?" Li Er didn't expect Qin Huaidao to inspect it, and this pragmatism was admirable.

Fang Xuanling also reminded: "The gentle places are easy to do, but the steep places are rocks, extremely hard, and the road is difficult to walk, this road is not easy to repair, and the construction period must be lengthened a lot." ”

Qin Huaidao didn't know how long the construction period would be, he hadn't calculated it, so he didn't dare to say it full, and explained: "Holy Lord, there is a way for the minister to easily open the mountain and shorten the construction period. ”

"Tell me about it!" Li Er suddenly became interested.

Everyone was also very interested, and they all looked at Qin Huaidao.

Qin Huaidao was a little hesitant, the explosives were not trivial, but this thing could not be hidden from the court, and it was not good to hide it, so he organized the language and said: "The minister knows a thing, he can blow up the hard rock, and he doesn't need to boil the fire and splash it, the speed is much faster, and when the minister develops it, please ask the saint to take a look at it on the spot." ”

"But the method obtained by the pre-Qin Warlock Cave Mansion?" Li Er's eyes lit up and he asked.

"Exactly!" Qin Huaidao secretly sighed, this excuse is really good, so as not to explain the source.

Li Er did not doubt him, he was overjoyed, and said: "Great, I waited to take a look, I didn't expect the pre-Qin warlock to master such a magical method, fortunately, he was obtained by Huaidao, this is also the blessing of the Tang Dynasty, the blessing of me, Huaidao, can there be any mention of the method of immortality in the relics of the cave?" ”

"The method of immortality?" Qin Huaidao's face changed, how could this emperor who has been famous for thousands of years want to live forever, from Qin Shi Huang to future generations, without exception.

Facing Li Er's extremely enthusiastic gaze, Qin Huaidao suddenly thought of another question, this Li Er is afraid that he really wants to live forever, if he says no, will he have doubts about the pre-Qin warlock? But I really can't.

Seeing Qin Huaidao's hesitant expression, Li Er thought that there was really a method of immortality, and suddenly became excited, and his voice trembled a little: "Huaidao, can there be such a method?" ”

The ministers also looked at each other, and their eyes were a little complicated.

Qin Huaidao didn't know what everyone thought, but he knew by himself, where was the method of immortality, but if he directly said no, it was estimated that Li Er would be disappointed, and even suspected that he would not give it, after thinking about it, he still said with a straight face: "Saint, the four seasons alternate, birth, old age, sickness and death, this is the way of heaven." ”

"That's not it?" Li Er's face sank, and his eyes sharpened.

Qin Huaidao saw that he was really suspicious, and said with a wry smile: "Sage, the first emperor destroyed the six kingdoms to dominate the world, swallowed mountains and rivers in anger, made high achievements, and pursued immortality in his later years, but was deceived by a small alchemist and became a stain, and the ability of the Confucian sage Confucius has never been immortal, it can be seen that the way of heaven cannot be violated, there is no way to live forever, but there is a way to live long." ”

"What do you mean?" Li Er's spirit was shocked and asked.

Many ministers also stared at Qin Huaidao tightly and pricked up their ears.

Qin Huaidao faced everyone's questions and smiled calmly: "Life expectancy is rarely more than 100, but the method of health preservation, not to say 100, eighty or ninety is not a big problem." ”

"Do you have this regimen?" Li Er was unsettled, his eyes shining.

"The minister understands a method, the name is Taijiquan, and he practices every day for about half an hour, which can nourish qi, cooperate with dietary conditioning, and add the minister's tea, and the longevity of eighty or ninety is no longer a problem." Qin Huaidao said with a smile and took advantage of the situation to make a wave of advertisements.

"Okay, go back and teach me." Li Er said.

Qin Huaidao saw the eager eyes of the ministers, wanted to be embarrassed to speak, thought of his tea business, and hurriedly said: "Shengshang, Taijiquan is simple and easy to learn, you must insist, the ministers will never hide their selfishness, it is better to teach it now, all the ministers are my Hongguo, it is better to learn them all, and you can spend more time worrying about the saints." ”

The ministers' eyes lit up, this reason was not too good, seeing Qin Huaidao's eyes, he became more and more satisfied, and they all agreed: "That's right, let me wait and learn, live a few more years, and be loyal to the saint and share worries." ”

Li Er has a deep affection for the old people around him, and he can't bear to watch everyone leave one by one, his old age is miserable, if everyone lives for a few more years, he can save a lot of worry, and the country will be forever.

Thinking of this, Li Er smiled with satisfaction: "Yes, but don't forget the kindness of my son-in-law." ”

"I can't forget!"

"Bad way!"

"And that tea, I'll buy some later."

Everyone said, excited, to everyone's status, who doesn't want to live a long life?

Qin Huaidao saw that the advertisement was working well, and a handful of silver rolled in, and smiled with satisfaction, as for Taijiquan, it was all over the streets in the future, and there was no need to keep it secret, so he signaled that after the unrelated people left, he taught it on the spot.

From theory to luck, to boxing, slowly come and demonstrate one by one.

They are all people who have practiced martial arts, and they learn very quickly, and they can master everything in half an hour.

Everyone compared, pondered carefully, felt the deep meaning, and gradually had a understanding, Fang Xuanling deserved to be the head of the civil officials, the fastest and deepest, and said in surprise: "Huai Dao, this set of boxing methods contains the way of yin and yang, the meaning of endless life, holding the yuan, one, one is the way, this is the meaning of integrating the body and the Tao, right?" ”

Qin Huaidao said with a smile: "It is exactly like this, to control the qi with the will, to control the action with the qi, and to combine the will, qi, and shape into one, so that the spirit, qi and blood, viscera, muscles and bones of the human body can be warmed and exercised, and the balance of "yin and yang secret" can be achieved, so it can play the role of curing diseases and fitness without diseases, and ensure the health and longevity of the human body." ”

Anyway, practicing Tai Chi is only good for the body, there is no harm, I am not afraid of side effects, and I can sell tea and make a lot of money.

Thinking that everyone is half the age, they may not have much time to practice when they get up early in the morning every day, and they may not have much time to cultivate, so he reminded: "Holy Lord, this method is best to practice at the same time, people have just woken up, the spirit and spirit are the most vigorous, and the cultivation effect is the best, but there are some conflicts when you need to meet in the court." ”

The cancellation of the early dynasty cannot be explained thoroughly, and it will stop at the point.

Everyone is a human spirit, how could they not understand the meaning of Qin Huaidao, they all looked at Li Er, Li Er was a little difficult, on one side is the country, on the other hand is longevity, after thinking about it, he decided to go back and study and study, find the best of both worlds, and smiled with satisfaction: "I have written it down, did you send some tea into the palace, swing the car, and go back to the palace!" ”

I came here this time to ask about Zhou Zhizhishu, but I didn't expect Qin Huaidao to have a plan, and he also saw the wonderful sand table and learned the method of longevity.

Suddenly thinking of the fourth child's request, his mind suddenly became bad, but his own baby, he still has to say it, he looked at Qin Huai with an apologetic face: "Huaidao, someone in the fourth mansion is bold and reckless, smashing your shop, the crime deserves death, but the person has been killed with a cane and punished, and the fourth child is also willing to apologize to you, do you think about this?" ”

There is only one who can be called the fourth by Li Er.

The nickname of the fourth child also shows Li Er's favor for King Wei.

Qin Huaidao didn't plan to let go of King Wei, he used to make trouble because of the briquettes, but now he has come out again, how dare a subordinate not be instructed by his master? But refusing Li Er's peace is definitely not good, not giving the saint a son, it is disrespectful, Qin Huaidao's heart moved, and he pretended to be flattered and said: "It's all a trivial matter, and I can't afford to speak in person from the saint." ”

"Have the courage, I didn't mistake you, go back and let the fourth child come to the door in person." Li Er said with satisfaction.

Qin Huaidao pretended to be satisfied and smiled: "The saint is serious, he can't afford to be the king of Wei in person, everyone knows that the king of Wei has great talents, has the style of the saint back then, the saint loves the king of Wei, just as Gaozu loved the saint back then, how can such a talented prince condescend to be noble, and he should be a courtier." ”

If you don't shoot, you will kill!

These words were murderous and heart-wrenching, and they sounded in everyone's minds like thunder.

Everyone's faces changed drastically, and they all looked at Li Er, everyone saw these words thoroughly, but no one dared to say them.

Li Er also had thunder rolling in his mind, thinking of Gaozu's favor for him back then, thinking of his full-fledged and famous, and finally having to kill his brother to seize the throne, and now he loves King Wei, in time, wouldn't he also follow his example and look at the prince with a knife?

Thinking of this, Li Er's heart trembled inexplicably, and he was a little more flustered, this kind of panic has never been seen since he ascended the throne.

The next moment, Li Er glanced at Qin Huaidao deeply and turned to leave.

The ministers hurriedly followed, Li Jing looked at Qin Huaidao, sighed, and said in a low voice: "You, you're too impulsive, think about the aftermath, I'll explain one or two things there." He said and left in a hurry.

Fang Xuanling also glanced at Qin Huaidao deeply, didn't say anything more, and caught up.

The conversation turned cold in an instant.

But Qin Huaidao didn't care at all, King Wei had to bear his anger if he dared to make a move.

Li Er walked out of the Ministry of Communications, got into the carriage, and drove back to the palace.

Li Jing and other ministers chased them out, and when they saw this scene, they all sighed, and Fang Xuanling said: "Go back and perform your duties and wait for the holy will." ”

They were all human spirits, nodded their heads, and got into their respective carriages to go home.

Li Er sat in the carriage with a cold face and was silent, his mind was full of Qin Huaidao's words just now.

As a father, Li Er's choice for the prince in his heart is the crown prince, and he has not wavered a bit, he doesn't feel that there is a conflict between the choice of pampering King Wei and the prince, there is any problem, and no one dares to remind him in person and provoke it.

Qin Huaidao didn't directly pick it up, but it was more deafening than it, so that Li Er was alert, as a person who came over, Li Er knew very well that even if King Wei didn't have an idea, he would be pushed to that position, just like himself back then, Xuanwumen has only been more than ten years in the past, isn't it going to reappear again?

How aggrieved, painful and helpless he was back then, and now, isn't the prince as aggrieved, painful and helpless as he was back then? It's no wonder that when I was a child, I was benevolent, pure, and filial, but when I grew up, I made all kinds of unreasonable actions, which turned out to be caused by my indirect injury.

Tiger poison does not eat children, but he inadvertently provokes brothers to kill each other when he thinks he loves it? How will history record itself in the future?

Terrible thoughts flashed through me.

Fear, guilt, self-blame, nervousness, all kinds of emotions welled up in my heart.

Back to the imperial city, Li Er did not allow anyone to follow, and came to the Lizheng Hall alone, which is the sleeping palace of the eldest grandson queen, although the person is not there, but everything in the palace is as usual, Li Er has a will, no one is allowed to move the decorations in the palace, see things and think about people, and the queen's voice and smile emerge.

Li Er looked at the portrait on the wall, he couldn't help himself for a while, and muttered: "Guanyin, am I wrong, I am in the royal family, where are the people of ordinary families who are ethical." ”

"Guanyin, what should I do?"

The voice is sad and sincere, as a father, Li Er will never allow his brothers to kill each other, nor do he like discord among his children, as an emperor, he doesn't want to see the reappearance of Xuanwumen, but Li Er is a human after all, a father of children, and he has love and preferences in his heart.

"Is it wrong to pamper your own children?" Li Er looked at the portrait steadily, as if he was asking, and as if he was questioning, and he couldn't let go for a long time.

This stop is an hour.

Outside the main hall, Wang De led a group of guards and entourage to wait hard, not daring to move.

King Wei came over and asked, "Father-in-law, is my father inside?" ”

"I've seen King Wei, the saint is here!"

"This king goes in and sees." King Wei said as he walked inside.

Wang De was shocked and hurriedly shouted: "King Wei can't go in." ”

"Why, this king can't go in? My father has always loved me, and he won't be angry. King Wei said nonchalantly and continued to walk forward.

In the hall, Li Er heard it sincerely, and said bitterly in his heart: "Sure enough, the fourth child is a little self-righteous and inflated by his love, and he is in an ordinary family, and there is nothing wrong with loving his children, but as an emperor, he has already set up a prince, even if he has love, he has to hide it, and he can't be too partial when riding a horse, otherwise it will make people have thoughts that they shouldn't have. ”

Thinking of this, Li Er's speculation about Qin Huaidao disappeared, and he slowly turned around and stared at King Wei who came in, still with that easy-going expression with a smile, looking at it is festive, which makes people love, if it was in the past, Li Er would be concerned about a few words, but at this moment, his mood quietly changed, thinking that maybe it was time to let it go!

Once the prince is crowned king, he needs to leave Chang'an and go to the fief, and he is not allowed to enter Chang'an unless he is summoned.

But Li Tai, the king of Wei, was deeply favored by Li Er, even if Empress Changsun reminded him, he didn't go to the fiefdom, and stayed in Chang'an, and many ministers also reminded him, but Li Er never listened.

Li Er, who woke up, realized that he had done something stupid, but fortunately it was still too late.

Seeing that Li Er was silent, Li Tai, the king of Wei, did not have the concern of the past, and even his eyes did not have the kindness of the past, but showed a little alienation and a little scrutiny, his heart trembled inexplicably, and he hurriedly saluted: "The son has seen his father." ”

"Emperor, are you twenty years old?"

"Back to my father, next month will be Erchen's twentieth birthday!"

"It's really fast, it's twenty in a flash, and after next month's birthday, you can go back to the fiefdom and become a vassal." Li Er said suddenly, glanced at Li Tai deeply, and walked outside.

Li Tai's face changed greatly, and his body was cold, but he didn't dare to say a word.

It wasn't until Li Er walked out of the Lizheng Hall that Li Tai reacted, looking at the portrait of the queen hanging on the wall, kind, kind, and the shallow smile seemed to be comforting and persuading, but it made Li Tai angry, and he couldn't tear the portrait off, tear it apart, and trample it under his feet.

But in the end, I didn't dare.

Thinking of Li Er's methods and unambiguous character, Li Tai knew that he had lost after all, and he had lost completely, but he was unwilling, and came out with a cold face, and saw that his father had gone away, so he hurriedly caught up, pulled a Qianniu guard and asked, "My father looked very angry, where did he go before?" ”

This Qianniuwei didn't think much about it, and said casually: "I went to the Ministry of Transportation." ”

"Ministry of Transportation?"

Li Taimeng thought of Qin Huaidao, the protector of the country, and thought of the grievances between the two sides, and immediately guessed that Qin Huaidao must have said something, or did something to make his father have other thoughts.

At this moment, Li Tai's face was like frost, endless resentment arose, his fists were clenched, and a voice roared in his mind: "Qin Huaidao, you are so ruthless, this king and you are incompatible." ”

A cold light burst out of the fat eyes!

……

Qin Huaidao didn't know that he was remembered by Li Tai, the king of Wei, and he was not afraid of it, since he chose to open his mouth, he was mentally prepared, and returned to the house after dealing with official business for a while, and as soon as he sat down in the study, He'er hurried in: "Young master, several people from the Guogong Mansion have come up, and there are also people from the palace, saying that they are purchasing tea." ”

"One person packs five catties, it is said that there is not much stock, first will be served, drink and then come, one catty will be charged according to the usual silver, half of the tea in the house will be sold in the shop, and the same purchase limit as wine, one person can only buy one catty a day, and can only sell fifty catties a day, not more." Qin Huaidao admonished.

Once the news spreads that drinking tea can lead to longevity, and both Guogong and Shengshang are drinking it, the market will definitely rise.

"Remembered." He'er hurriedly agreed, obviously there was a lot of speculation in the house, and he couldn't figure out why Qin Huaidao said that the stock was not enough, but he kept his duty, didn't ask more, and went in a hurry.

"Wait a minute." Qin Huaidao shouted, picked up charcoal and paper to draw some tea set styles, there are teapots, teacups, fair cups, note the firing method and key points, and then handed it to He'er: "Let people send it to Qinjiazhuang, let Huang Lao arrange someone to make two hundred sets, leave ten sets in the house, and sell the other shops with tea, sell them according to two sets or not, it doesn't matter if they can't be sold, the firing method is confidential, by the way, where are the ladies from Wanhualou?" ”

"They all live in the East Courtyard, usually sing and sing, and be a female celebrity, but they don't want to go out and walk around, saying that it is rare to be quiet, do you want to call?" He'er hurriedly said.

"Let them do a set." Qin Huaidao said, the east courtyard is inhabited by the family members of the subordinates, there are a lot of female scrolls, it is a little inappropriate for me to rush over, the study is big enough, and it is convenient to talk about things.

It's time to teach everyone to sing, but what is it good to teach? Qin Huaidao pondered, and all kinds of songs in later generations came to his heart, and he picked up a brush and wrote the lyrics silently.

Not long after, led by Dong'er, a group of women walked in, many people were still holding musical instruments in their arms, everyone came to the house for more than a month, but they had never seen Qin Huaidao, fortunately, the house was calm, there was no intrigue, the days passed by the clouds and the wind was light, and it was rare to be quiet, so everyone was not flustered.

But seeing Qin Huaidao again, everyone was inexplicably a little nervous, worried about the tranquility in front of them, the beauty disappeared again, worried that Qin Huaidao had other thoughts, and at the end of the good days, one by one they became cramped and uneasy, not that they were afraid that Qin Huaidao would have a wrong thought, and they would be favored by the protector of the country, everyone couldn't ask for it, and they were worried about being sold again.

Once a person has come out of the darkness, he does not want to go into the darkness again.

Feeling everyone's uneasiness, Qin Huaidao smiled and said, "Just sit casually, you're still used to it, right?" ”

"I'm used to it, everyone in the house is kind, and they are also enthusiastic about us, and they don't mean to look down on us, thank you to the Protector for taking them in." Dong'er said on behalf of everyone.

"Don't be nervous, I called you here mainly to teach you to sing some tunes, so let's sing a cappella first, you can compose music, and if you can't, learn to sing, see whose voice is suitable." Qin Huaidao explained his intention with a smile, so as not to be nervous and uneasy, this song could not be taught.

Seeing that Qin Huaidao really planned to teach music, everyone waited a little in their hearts, and became more curious, wondering what kind of song it would be if they also knew how to compose and sing music after Jiangmen?

Their eyes flickered, full of anticipation.
