Champion County, where the shogunate of the Northern Army is located.

Yu Ban wears a half-worn plain brocade robe, and is holding a bamboo broom to clear the thin snow in the courtyard.

Now his face is thinner, but he is full of energy, his hair and beard are all white, and his gestures are full of calmness, and he does not see the color of decay, not like a general who was captured by two defeated armies.

The sound of horses' hooves came from far and near, and the sound of hooves shook the snow in the treetops.

Yu Ban stopped the broom, turned his head and saw the figure of Tian Xin outside the low fence, and behind Tian Xin was a rider who was obviously shorter.

These riders are divided into two kinds, respectively with the words 'Wudang' and 'Xiahou' on their backs, all of which are black-background vermilion flags.

With the rough knowledge of the scriptures, the 'bloodline' of these two flags can also be distinguished, and the color matching of the battle flag and the animal pattern totem are all exquisite.

Tian Xin does not use animal patterns to make military flags, and the text number is the flag and totem of each army; Now worship Yu Xia, Tian Xin defines Yu Xia as the country of water virtue, and the flag and clothing are still black.

And the aquatic wood, the Yin Shang after Yu Xia is Mude, so after the Guan family worships the Yin Shang Temple, the Guan family's principality soldiers will use turquoise as the banner and the main tone of the uniform.

As the three Kebin genera of the Han Dynasty, Tian's Chen Bing and Guan's Song Bing use the Han Huode Zhu Chi character and animal pattern as the core color of the banner.

Ji Zhou himself is a fire virtue, and the banner and uniform color of Zhang's guards are the same as those of the Han army.

After the Han Dynasty was introduced to the north, some scholars have explained this phenomenon by citing allusions between Liu Guanzhang and Tian Xin...... It's very reasonable, it's like heaven.

Yu Ban looked at the horsemen who dismounted outside the fence, and couldn't help sighing: "Prepare the feathers and fly, and the only difference is Tian'er." ”

This is what a friend in the north said in the letter, and the knot of defeat and surrender in the forbidden war has been untied, and it can be said that it has suddenly opened up.

Prepare for feathers to fly, but lack of fields.

This is the new popular prophecy in the north, there is a miracle of Gaozu before, and there is the legend of Emperor Guangwu, this prophecy quickly swept the north.

Guan Yu is the incarnation of Mude, and during the Battle of Xiangfan, Guan Yu had the tendency to burn himself to help ignite the Sanxing of the Han Dynasty.

Tian Xin was born in Hanzhong with water virtue, and was restrained by Tude, so Cao Wei entered Hanzhong, and Tian's family was ruined and fled to Jingzhou for refuge.

After Tian Xin Congrong, with water Deji Guan Yu Mude, so Guan Yu's Northern Expedition to Xiangfan can even fight Lianjie to break Cao Ren Tude to conquer the Southern Army, Gayin Mu Ke Tuye.

Because of the return of water to the Han Dynasty, the Han River surged and drowned in the Forbidden Seventh Army, and then broke Jiangdong Sun Quan twice in succession.

What kind of virtue is Sun Quan?

The king is about to be called, it should be Jinde, and it will be bred from Cao Weizhong, which is naturally Jinde.

Jindek Guan Yumude, Lü Meng crossed the river in white clothes, almost succeeded in plotting to capture Jiangling, and almost cut off Guan Yumude's foundation.

Fortunately, Tian Xin cultivated in Jiangling, and the river is also a big water, which is not conducive to the fire virtue of the Han Dynasty, but it helps the water virtue.

Jin and water, so Tian Xin twice broke the Jiangdong soldiers and horses on the side of the Yangtze River.

So Yu Ban looked open, and he saw it very openly, not that the sky was eyeless, but that the way of heaven was originally towards others!

Take a closer look at Liu Bei, there is no place to stand, and he can be called a wandering world.

Since he got the four counties of Jingnan as his foundation, he suffered a loss in the hands of Sun Quan and signed the Xiangshui Alliance. After that, he won successive battles, and Cao Cao, who occupied most of the world, had no temper.

Hou Tian Xin was born, and Cao Cao died again...... In short, this Da Wei looks like it's going to end.

Yu Ban gathered his thoughts, and saw Tian Xin walk in with a box of snacks and said with a smile: "The old general's complexion is dusty, which is gratifying." ”

"I would also like to thank Xiahou for teaching the living swordsmanship, I have a lot of experience in recent days, and I feel that my spirit is active, and my body and mind are warm."

Yu Ban introduced Tian Xin into the living room, the floor heating under the wooden floor was hot, Tian Xin took off his patent leather boots and sat on the ground, Yu Ban brought a black clay pot to boil water on the brazier, and grind the tea leaves for tea powder, ready to brew.

This is the way to eat tea that has only become popular this year, Tian Xin secretly fried less than two Han catties of tea, the temperature and technology were not mastered, but the taste was qualitatively leaped compared to the fermented tea.

In order to disguise the roasted tea technique, Tian Xin ground the tea leaves and drank them...... Yu Ban tasted it a few times, and now he grinds the tea powder with the tea cake that has fermented into black and red and uses it to brew, Tian Xin is indifferent to this.

The fried green tea has long been drunk, where is the excess forbidden?

"I heard that Xiahou wants to improve the summer calendar?"

Yu Ban pressed the small stone mortar with his left hand, and held the small wooden pestle with his right hand to grind the pieces of tea cakes: "Astronomy and calendar are ancient secrets, similar to historians and doctors, and most of them are passed down from father to son. Xiahou wants to innovate the summer calendar, why not consult the Central Plains Confucianism and famous masters? ”

"If Xiahou wants to write a letter, it seems that the other generation will gladly go to the appointment."

Yu said that he was gentle, holding a small wooden pestle in his hand and gently stirring clockwise in the stone mortar, this technique originated from the left rotation of the innate Taiji diagram, which is Shuntian; The acquired Taiji diagram is right-handed, which is against the sky.

"I already have eyebrows, and I don't have to worry about the people in the north."

Tian Xin said with a smile: "Old general, do you know where the Taiji diagram came from?" ”

Yu Ban Surong: "I have heard many people say that it is in the same vein as the ancient "River Map" and "Luo Shu". ”

The river map Luoshu, the picture is the map of the Tianhe, the river map is the body, and the Luo book is used, containing the universe, space, and mathematical changes.

"It's the Hetu Luo book, the Hetu Yan Taiji, the Taiji is divided into two instruments, the two instruments are four elephants, and the four elephants become gossip. And Vena is gossip. ”

Tian Xin caught the black tea soup handed over by Yu Ban, and took a sip before saying: "My family governs the Book of Changes, maybe the qualifications are acceptable, and I know the gossip when I see Luo Shu in the mountains, so I am the ancestor of the door wall, and I have to give the river Tuluo book." ”

Seeing Yu Ban's excited appearance, Tian Xin shook his head and smiled: "In fact, the Hetuluo book has been circulated in the world, but no one in the world knows it. ”

It is really circulating, and the sum of the mathematical arrangement of the river chart is equal to fifty-five, which is the number of the great Yan in the Honghuang text.

And the mathematical model of Vena ...... Elementary school students know it.

Just the one who wears nine shoes, three on the left and seven on the right, two or four for the shoulder, and six or eight for the foot, that is:

4 9 2

3 5 7

8 1 6

Before he has researched certain results, Tian Xin is not ready to publish the model of Hetu Luoshu, if anyone can reverse the Hetu Luoshu from the Taiji Bagua Diagram...... That's nothing to say, count him awesome.

What's more, the atlases of Hetu and Luoshu have been circulated in the world, but no one can connect these two maps.

The two are one, but the two maps that circulate are independent.

After taking another sip of tea, Tian Xin said: "I didn't expect that the generosity of the King of Han would enable me to enshrine the Yu Xia Sect Temple, so although the improvement of the Xia calendar is tricky, it is not difficult to formulate before the lunar month." There is the Book of River Tuluo, which formulates the calendar...... Hehe. ”

It's just a calendar, I don't explain it, I don't debate the scriptures and sources with others...... It's just that it was issued in Gongguo Chen, and he was both a contestant and a referee, which felt comfortable.

Why bother to displease yourself and call a bunch of people to study the calendar and give them a chance to steal?

These are all a bunch of elves, and a word they say inadvertently may be deduced from some academic achievements.

Therefore, if you want to keep the intellectual property rights that you copied, you must avoid dealing with these people.

Seeing this, Yu Ban no longer asked, Guan Ping would not easily ask for such a precious and magical thing.

Guan Xing has the opportunity to come into contact, and whether he can learn it depends on Guan Xing's qualifications.

The government military system is about to be implemented, and it is time to put it back in the ban.

After half a cup of tea, Tian Xin opened the food box: "Old general, I returned from Xiangyang this morning, and His Majesty asked me to bring a box of snacks to the old general." ”

Dahan has room for you to eat at home, depending on whether you want to eat or not.

Yu Ban stretched out his hand to pinch a snack and put it in his mouth to chew gently, his silver-white beard trembled: "I'm afraid I will live up to the love of the Han Lord, but Xiahou passed on the swordsmanship of the old and the living, and the old man could not be repaid, there is a volume of marching notes, I hope that Xiahou can choose someone to teach me the art of war." ”

As he spoke, he got up and brought a wooden tray from his bedroom, which contained a papyrus-bound manuscript.
