Du Heqiang pressed the joy brought by the great increase in internal force in his heart, stabilized his mind, took the sword, and practiced alone in the courtyard, until the internal force was exhausted, and then stopped.

After two hours, Duhe's spirit recovered, but his internal strength did not increase.

"Sure enough, it's not because of the exhaustion of internal strength." Du He sighed secretly and stopped pressing.

Cultivating internal strength is the most taboo for greed, so Du He stopped rationally and did not continue to investigate.

Duhe made the wisest choice here.

The infinite potential of human beings is beyond anyone's imagination. In times of crisis, an injured mother can move a boulder of 400 catties in an instant in order to save her child, and a trapped person can stay awake for ten days and ten nights without eating or drinking.

This is a unique human power that cannot be controlled by itself.

Du He's cultivation of internal strength has only been four months, and he can only be regarded as a rookie in terms of cultivation.

It is impossible for a rookie to hold a person of nearly 100 catties and use light skills to run two miles in one go, and he has to dodge the obstruction of the palace forbidden army in various ways.

But Du He did it, and he didn't know how to do it himself, he was just bent on saving Princess Changle at that time, and he didn't want to see a talented, virtuous and beautiful person die in his arms like this.

He didn't think about anything at the time, only one thought: that is, to save people, desperate to save people.

In this way, he unexpectedly stimulated his own potential, prompted him to make great progress in his internal strength, greatly increase his skills, and complete this unfinishable thing.

But this kind of forcible stimulation of one's own potential is quite harmful to the body, just like taking stimulants, if Du He is insatiable, continues to practice, and intends to find a quick way, his body and his meridians will be broken because he can't support this sudden surge of power, and he will go crazy.

There are many, many things like this in the martial arts world, but Du He has had an experience, so he made the most correct choice rationally.

After a night's rest, the next day Du He spent a whole day understanding the rules and regulations of the Tang Dynasty polo game.

Maybe it's because polo is a game of the aristocracy, so the polo game in the Tang Dynasty is not fierce, just like a group of girls playing, and it doesn't reflect the competitive spirit that belongs to competition.

It feels like basketball in the 90s and basketball in the 20th century.

Basketball in the 90s was exciting and intense, and watching Jordan's game was enjoyable, while basketball in the 20th century had many stars, but a slight collision was a foul, and it couldn't be compared with the ball game in the 90s.

The polo of the Tang Dynasty was played more than the basketball of the twentieth century.

If the same is true for a polo match, it is impossible to really hone the intention of honing the riding skills.

"We have to rewrite the rules to make the game more intense, more exciting, more attractive, better like rugby!" Du He held the tip of the pen in his mouth, said to himself, thought, sometimes moved the pen, sometimes frowned.

Little Lori Linglong was grinding ink on the side, her little face was red, her eyes peeked at Du He from time to time, her chest seemed to be a deer constantly impacting, and she kept thinking that the second young master was getting more and more handsome.

But as Linglong thought, Du He didn't look bad, but he used to have too much wine, and he looked like a plague chicken, which made people tired of watching. But now Du Changtian's epiphysis, so that Du He has the superior mental method of "Five Qi Dynasty Yuan", and has no bad habits, so he naturally looks more and more spiritual, plus the original Du Changtian's freewheeling, the temperament of the world is gradually embodied, and he definitely has the capital to fascinate thousands of girls.

Especially recently, Du He's internal strength has been greatly improved, and both spirit and spirit have been significantly improved, which naturally provokes the spring girl's heart to ripple.

Linglong's mind Du He is quite clear, but she is only thirteen years old, and Du He does not have the hobby of being a young girl.

On the same day, Du He sorted out the information in his mind, sorted it out a little the next day, revised it, and went to the palace with a stack of materials to find Li Shimin.

The place where Li Shimin met Du He was in the Ganlu Palace, which surprised Du He.

The palace where Li Shimin lives is called Taiji Palace, and the layout of Taiji Palace is very exquisite, and it is strictly implemented in accordance with the principles of ancient palace architecture. The main building of the palace adopts the principle of "sleeping in front of the front and sleeping in the back", and divides the palace into two parts: "front court" and "inner court" before and after the palace wall gates such as Zhuming Gate, Suzhang Gate and Qianhua Gate.

The "former court" is the place where the emperor handles government affairs, and the "inner court" is the place where the emperor rests and has concubines.

The Ganlu Hall is located in the "Inner Court", which is where the emperor studied in the Inner Palace, and it is also the third hall of the Taiji Palace, that is, the study of ordinary people.

Li Shimin did not receive Du He in the living room, but took him to his study, which can be regarded as a great honor.

Although Du He knew that this was likely to be a means of wooing Li Shimin, he couldn't help but be a little moved in his heart, if it weren't for Li Shimin's attention to his own ability, if it weren't for Li Shimin's fancy and appreciation of himself, would people bring him here?

"Duhe, meet Uncle Li!" Du He's words were released, and before he could bow down, Li Shimin's words came over: "Okay, there are only you and me here, no need to be polite." Take what you've brought to me. ”

When Du He came in, he thought that Li Shimin was the only one in the entire study, and his personal guards were blocked outside the house by him.

Du He walked closer and handed the things he had sorted out to Li Shimin.

Li Shimin stretched out his hand to take it and praised it with a smile: "Good characters, worthy of being a master of calligraphy, if the Manchu Dynasty civil and military can write such good words, then it will be a pleasure for me to review and read the chapters." ”

"What is this?" Li Shimin glanced at it, pointed to the punctuation, and something inexplicable flashed in his eyes.

"Punctuation!" Only then did Du He remember that the punctuation marks of sentence breaks were officially used in the late Qing Dynasty, and immediately said: "This is a method of sentence breaking, which can make it more convenient for readers to read." ”

"What a punctuation mark! It's a simple and convenient way to do it, but it's very practical. I plan to make it known to the world that it will be used widely, what do you think? Li Shimin asked with a smile, already seeing the meaning of the existence of small punctuation marks.

Du He smiled: "I don't have an opinion, it's just that the punctuation marks here are different, and each one has a unique meaning, so I'll just write it down and pass it out." ”

Li Shimin immediately nodded in agreement.

Du He picked up the brush in the pen holder, and saw that there was no ink on the inkstone, and couldn't help but be stunned.

Although three months have passed, Du He still has not learned the art of grinding ink.

Li Shimin saw that Du He hadn't started writing for a long time, smiled knowingly, got up and said: "Well, it seems that for the sake of you, a famous calligrapher, I will make an exception and personally polish the ink for you." ”

Li Shimin skillfully polished the ink and made a gesture of please.

Du He's heart fluttered, and he became more and more respectful of Li Shimin, the emperor, and shook this spirit, and wrote out the use of punctuation marks such as periods, commas, question marks, exclamation marks, pauses, semicolons, etc. in detail.

Du He is a top student in the Chinese department, and writing these things is really a piece of cake for him.

Li Shimin did not look at the materials brought by Du He, but stood behind him, watching him write seriously, and learning his penmanship seriously.

Seeing Du He stop writing, Li Shimin still shook his head and sighed: "Du Tizi, my favorite, I have practiced hard for a long time, but it is still difficult to grasp the mystery. ”

Du He will also smile, Du Ti character originates from Yan Ti character, Yan Ti character is recognized as one of the difficult to write fonts, in the Tang and Song dynasties, the achievement of Yan Ti character even surpassed the various fonts left by the sage Wang Xizhi, but it is because it is difficult to learn Yan Ti Zi, so there are few people who are really famous for Yan Ti characters.

Although Li Shimin is very good at calligraphy, it is like comprehending the essence of Du Ti characters for a few months, which is simply whimsical.

"If Uncle Li wants to learn, how dare Du He hide it privately!" Du He said with a smile.

Li Shimin laughed heartily when he heard this.
