What are the restless princes, Gu Cao and Bo Yao?

Guangling, the south bank of the ancient Yangtze River, the main tent of the Jiangnan camp, Lu Di picked up the military book, wanted to read it, and finally put it down, his mood was very bad, although he had expected the rainy season to come, but he didn't expect the rain to be so heavy.

Also, now the north is still controlled by the high-pressure belt, and the low-pressure humid air mass in the south is blocked in the basin on the south bank of the Yangtze River, and there is no stamina to go north, and therefore the rain that should have fallen in the north is all falling in the south at this moment, so it is understandable that there is a great drought in the north and a flood in the south.

Lu Di now just hopes that the flood will come later, at least after he has finished swallowing Wu, and then it will happen.

Looking at the rain outside the tent, Lu Di couldn't think about it again: this battle into Wu has no natural advantages for the Qi army now: first, in the rainy season, the waterways are muddy, and the grain and grass are difficult to transport, and the grain and grass are easy to mold under this hot and humid conditions, which is a huge challenge for the army's logistics; Second, although most of the soldiers gathered for the battle of Swallowing Wu were people who lived in the equally humid Sishang or coastal lakes and swamps, it could not be ignored that most of the fierce generals in the army were from the north, and it took them a while to adapt to the humid and hot climate in the south, and this period was the worst time for combat effectiveness; Third, the memory of the first battle of Chu, the Allied army almost wiped out by the plague, made Lu Di dare not forget it for the rest of his life, he was afraid that too many people would die in the war, and in the environment of so many damp and hot mosquitoes, that scene reappeared again.

Every time he thought of this, Lu Di was a little irritable.

But irritability can't solve the problem, the problem is there, and Lu Di can only take corresponding measures to deal with it.

For example, on the one hand, he gave Chang Sangjun and Bian Que absolute power to comprehensively supervise the soldiers' clothing, food, housing, transportation, food, drink, and Lazar, but there were too many soldiers and poor self-discipline, so there were few omissions in supervision.

Fortunately, although the soldiers were a little angry by the rules, they knew that their own monarch was also for their own good, so they were moved and helpless to endure it at the moment.

On the other hand, Lü Di arranged for the commanders of the Jiangnan battalion at all levels to attack the nearby cities with elites, and as long as these cities were taken, the army could be arranged in the city, which was beneficial for the sergeants to quickly adapt to the climate south of the Yangtze River.

Seeing that the rain was still falling, the only thing that could comfort Lu Di now was his family letter and his Si Zai (similar to the later Qin Tianjian who was in charge of the celestial star official calendar) Gu Bu Ziqing and Zong Zhu Ji Xian.

Lu Di read the family letter sent by Yayu again, and the family letter said that Tengyu was pregnant, Zhong Lichun and Zheng Dan were about to give birth, and Lu Wen and Lu Yan were making trouble at home.

Lu Di put away the family letter, and secretly felt proud in his heart: Hehe, we are still very capable of Lu Di, and now that we have only passed the year of establishment, we already have Lu Qu, Lu Wen, Lu Yan, Lu Ling (the daughter born to Lu Di and Nanzi, Lu Di privately married her), two sons and two daughters, plus the upcoming four, hehe, eight babies, haha......

How did Lu Di know that in fact, he already had eleven children, because the female minister and the female lord of the country and Bai Di's white long legs each gave birth to a daughter and two sons for him.

Just as Lu Di was smirking, Ji Xian's divination had already had a result.

Lu Di woke up from his own smirk when he heard the turtle shell cracking, and he looked at Ji Xian and Gubu Ziqing.

After Ji Xian finished reading it, Gubu Ziqing looked at it again, and finally the two reached an agreement, saying that this was the hexagram of Zhongfu.

When Lu Di heard that it was Zhongfu, he couldn't help but wonder what Zhongfu was?

The two said: Ze has a wind and calls it Zhongfu.

Lu Di asked Zhongfu about the others, and the two explained them one by one, saying: Zhongfu is another hexagram, the main image is Ze, the guest image is the wind, Ze is quiet and deep, and the strength is positive, nourishing all things, the wind is smooth and soft, and everything moves.

Take nourishment as the bottom, take action as the top, take nourishment as the foundation, and take movement as the spirit......

The cracked hexagram shows that the dolphin fish is auspicious, and the river is good for the big river, and the good is for the ancestors, which means that the pig and the fish are used to sacrifice the ancestors for auspiciousness, which is conducive to wading over the big rivers and rivers, and is conducive to persevering.

Lu Di nodded, he wondered in his heart that he should find a time to sacrifice the heavens and the earth and rivers, after all, this southern expedition mainly involves many rivers, lakes and rivers.

This is not Lu Di's religious superstition, but his worship of ancient Chinese mysticism in later generations.

Some people say that this is feudal superstition, which is false and not credible.

So what is credible in this world? Is it scientific?

How many years was Copernicus' heliocentric theory credible?

How many years have Newtonian mechanics been believed?

What is credible is called mystery, and what is not credible is called science, because science has a lifespan, and there is no mystery.

It's like he Lu Di was covered at the bottom of the coffin in a daze, and then woke up and became Qi Jinggong's beloved son, can it be explained by science?

At least not yet!

But primitive mysticism can.

Ji Xian continued to talk about hexagrams and self-help strategies, and Gubu Ziqing interjected from time to time to add, and Lu Di was fascinated by what he listened.

Lu Di is now more and more aware of "Yi", not because its predictions are sometimes really accurate, but because of the philosophical logic it contains, which makes people feel like eating a meal made with a big cigarette shell as a condiment.

He remembered what Lao Tzu of Zhongnanshan muttered to himself before he died, and now Lu Di understood a little, and he summarized it as the four stages of the Tao of life, which are hearing the Tao, knowing, seeing the Tao, and obtaining the Tao.

Lao Tzu said that he saw the Tao, but he couldn't reach it, in fact, he didn't get the Tao.

But who in this world can attain the Tao?

All who have attained the Enlightenment are floating in the heavens.

Lu Di took back his messy thinking, and he asked Gubu Ziqing what "Yi" is?

Ask him why he led his army south to encounter such an overnight rain, is this considered difficult?

If it is difficult, how difficult life is, and since it is so difficult, why is the hexagram called "Yi"?

Isn't that the opposite?

Gu Bu Ziqing's explanation not only tells the history of Yi from the Three Emperors to the present, for example, how Xia Zhi's "Lianshan Yi" and Shang's "Guizang Yi" were formed and developed.

Lu Di knows a little about the history of "Yi", but from the mouths of Gubu Ziqing and Ji Xian, the results that shocked him were different.

Ji Xian said that in fact, there are many other "Yi" that have been lost, or are facing loss, such as "Three Graves Yi" is one of them.

Lu Di heard that some ancient books had been lost, or that they existed, but no one could understand them, expressing deep anxiety and regret, and it seemed that he was still late in establishing the Daqi Museum and Daqi Library.

Then Gubu Ziqing pulled Lu Di to the front of the tent and asked him to look at the rain that continued to fall outside the tent, but Lu Di didn't know what he meant.

Gubu Ziqing picked up the bowl with water and stretched it out of the tent, and the rain dripped into the bowl, ripple after ripple.

"Your Majesty, look at the moment when the rain drops in the bowl of water, it has no waves but has a tendency to make waves, this is easy"

"What is the difficulty of life, is the waves after this easy trend, because of the waves, we feel difficult"

"But it's hard! Your Majesty, think about the wind and think about the boats, they blow on the surface of the water and float on the water, and when they leave, what is left on the water? ”

"Still calm water! Look at what you're looking at again," said Gu Bu Ziqing, pointing to the muddy road outside the tent.

"The mud of this road is more difficult than the water, but people can leave deep footprints when they walk through it, this is the true meaning of easy!"

Lu Di seemed to have some understanding, at this moment he saw Boya wearing a cloak and hat coming quickly from the rain, he saw Lu Tugu Bu Ziqing and Ji Xianhou first saluted and greeted, and then went to the tent door to hand over the cloak and hat to Wei Lang, changed into a pair of clean shoes, tidied up the clothes before following Lu Di and the three into the tent.

"Your Majesty, the official letter from the Taiwei has arrived" Boya Yan bowed and walked briskly, holding a sealed bamboo tube in his hands and walking towards Lu Di.
