People look up at the sky and see luminous objects, which are "stars". The stars are not isolated. People use their imagination to organize them into various shapes, so there are "images". "The Book of Changes · Xi Cishang" said: "An image is formed in the sky, formed on the ground, and changes are visible."

　　 The changes in the sky originally came from astrology.

When mankind looks up at the starry sky, observes astrology, and thinks about its periodic changes, they will find that the sun rises from the east and sets from the west every day, and the moon is round and missing, missing and round; if it is in the northern hemisphere, it will also find the top of the head. The North Star on the sky is always shining, while the other stars are in a weekly movement; if you are a persistent observer, you will find that the movement of the sun and the moon is related to the seasons, and the seasons are related to the agricultural harvest. , The distant celestial phenomenon is not indifferent to human destiny and human production.

　　 However, it is the same to observe the starry sky, but different people see different worlds and get different experiences. A part of manpower seeks the accuracy of observations and adds mathematical explanations, thus forming astronomy. Another part of the people play the role of imagination, and add words to explain, so the formation of starry sky myths, and these myths often evolve into legends, stories and folk customs.

　　 In ancient China, astrology was astronomy, which is an ancient magical science!

　　 Astrology has a history of at least several thousand years in China, but the real history may be even more distant. In essence, it and "Tai Chi", "He Tu", "Luo Shu", "Zhou Yi", "Bagua", etc. are all derived from prehistoric civilization.

　　 The ancients believed that “heaven and man interact” and “heaven and man are one.” From the changes in celestial phenomena, it is possible to infer what is going to happen to mankind. People walk in harmony with the sky, and the "sky" will be auspicious, and the world will be plentiful, the weather will be smooth, the country will be peaceful. If people act against the sky and do bad things, "the sky" will give a bad omen, and the world will suffer from drought and rain, floods, mutinies, and civil chaos. Therefore, the ancients attached great importance to the observation of celestial phenomena.

　　 In the Tang Dynasty, the imperial court established the "Taishi Bureau" and "Qin Tianjian", etc., which were specifically responsible for astronomical observation and prediction of good and bad luck.

Li Zexuan has never been in contact with the science of astrology in his previous life or in this life. The first reaction is naturally not to believe it, but the person in front of him is Li Chunfeng, and this prediction is completely consistent with history. In this way, he can't help but be wrong. A feeling of admiration and reverence has arisen in this discipline!

　　 "The science of astrology is profound and mysterious. It is hard to believe your Majesty just by relying on the words of the Taoist leader!"

　　 Li Zexuan pondered for a moment and said.

Li Chunfeng's eyes sank slightly, and he said every word: "Your Majesty will believe it! Because according to the observations and calculations made by the astronomical telescope in these days, there will be a Tengu Eclipse Day in three days! According to ancient records, the first moon solar eclipse, People are sick; the solar eclipse in February will cause much loss; the solar eclipse in March will cause floods; and the solar eclipse in April and May will cause severe drought and severe hunger! If Lord Hou and Your Majesty do not believe it, wait for the tengu food two days later Day!"

Li Zexuan was shocked that a solar eclipse may be a very normal astronomical phenomenon in the eyes of modern people, but in the eyes of ancient people, it is not unusual at all. In many cases, solar eclipses often signify a bad omen. It indicates that there will be treacherous people, faint kings in the country, or there will be catastrophes! If someone from the public takes the opportunity to confuse the crowd to do things, it is easy to succeed!

Thinking of this, Li Zexuan looked at Li Chunfeng with a serious face, and said: "The matter of the eclipse of the Tengu eclipse the sun is of great importance. Your Majesty must be prepared early, otherwise if it is used by someone who is interested, Chang'an City will surely be in chaos! Please also Go to the palace as soon as possible!"

Li Chunfeng nodded, and said: "Then Pang Dao, then go to the palace and see your Majesty! Thank you Lord Hou for the astronomical telescope provided to Pang Dao these days. If not, Pang Dao can't be so sure that Tengu food will appear in three days. day!"

　　 "Hehe! Mr. Dao is kind!"

　　 Li Zexuan arched his hands and said with a smile.

　　 Li Chunfeng clasped his fists in a bow and turned away.

Li Zexuan in the office suddenly became serious. He turned to look out the window and looked at the busy villagers at the foot of Yunshan. He thought that in the next few months, there would not be a drop of rain, and after the severe drought, it would be accompanied by Thinking of these locust plagues, he felt a little distressed in his heart for the people who were working in the fields, and then he hesitated for a moment and turned directly to go out.

　　 "Shanchang, where are you going?"

　　 Mo Zhong's voice came from outside the door.

　　 "Go to the dam!"

　　..............................

　　 In this era, there is no artificial rainfall, no pump irrigation. To fight drought, the most direct and effective ones are dams and waterwheels! For example, Dujiangyan in the land of Bashu has protected and nourished the people of Bashu for nearly a thousand years, and created the reputation of "the land of abundance"!

　　 The current Bahe Dam was specially built by Li Zexuan to protect the people of Lantian County!

It has been more than four months since the construction of the Bahe Dam started, and tens of thousands of craftsmen and civilians have been used. After the key problem-the closure of the river, has been solved previously, the construction progress of the dam can be described as rapid progress, but to what extent, Li Zexuan I really don’t know. On weekdays, his attention to the dam is still not enough!

When he came to the construction site of the dam next to Mei Village, Li Zexuan saw a wide **** running north and south of the Bahe River. It looked very mighty and majestic. Seeing this scene, Li Zexuan nodded secretly. Obviously, the main construction of the dam has been basically completed. The rest is the details!

　　 "Shanchang, are you here?"

As soon as Li Zexuan arrived at the construction site, his servants went to report to Mo Huai. Mo Huai hurried over after hearing the news. There was a lot of mud on his clothes, which looked like a scholar of academy. Very different.

　　 Li Zexuan nodded and asked, "Mr. Mo, how is the dam now being built?"

Mo Zhong pointed to the dam on the river and smiled: "Look at the mountain leader, the main body of the dam has been completed. Now it is mainly preparing for the installation of generator sets in the dam, such as power generation warehouse and control room. , And various switches, gates, etc."

Li Zexuan nodded in satisfaction, and then said: "Well, this speed is very good! I just don't know if the current dam can first put down the gate and block the diversion channel to store water? As for the power generation warehouse and control room, can they store water at the same time? While building it?"

Mo Zhong didn't know why Li Zexuan wanted to store water so eagerly, but since Li Zexuan proposed it, he had to consider the feasibility of such an approach. After thinking for a long time, Mo Zhong nodded and said: "I will store water first, then build This is indeed feasible for the generator-related parts! However, this will inevitably slow down the construction of the hydropower station slightly!"

　　 Li Zexuan smiled and waved his hand and said, "It doesn't matter, it doesn't matter! Hydropower stations don't have to be anxious for a while, it's the so-called slow work and fine work!"

　　Mo nodded at the hour, and said: "In this case, Mo has ordered people to prepare well, and at the latest tomorrow morning, the dam can start to formally store water!"

　　 Li Zexuan only noticed the little mud spots on Mo Zhong's body, and the shoes that had been soaked in the mud water in the river. He couldn't help but be touched, and then he said:

"Mr. Mo has worked hard for the construction of the dam in the past few months, but because of mundane things, the boy rarely comes here to help. It is really a shame! The Bahe Dam can be completed so quickly, absolutely cannot do without Mr. Mo For the tens of thousands of people in Lantian County, the boy thanked him for his hard work day and night!"

　　 After that, Li Zexuan solemnly bowed to Mo Zhong!

　　 "Hey! Can't do it! The mountain leader can't do it!"

　　 Mo Zhong was caught off guard by Li Zexuan's gift. After he reacted, he quickly stepped forward and lifted Li Zexuan up, saying:

"Mountain long, the Bahe Dam has condensed your wisdom and the energy of tens of thousands of craftsmen on this site. Mo just did what he should do and dare not take credit! What's more, the ancestors of the Mo family, back then, pityed the people of the world Suffering, I just want to rely on his talent in siege equipment to make the people no longer have "difficulties in farming", and all live a good life. Now Mo is just practicing the will of the old man of the holy ancestor!

Once the Bahe Dam is completed, it will definitely ensure that the people of Lantian County will no longer be afraid of drought. So Mo Mou would also like to thank the head of the mountain, and thank the head of the mountain for giving the people of the Mo family such a way to use what they have learned and benefit the people. If not, it would be even harder to benefit the people of a county with the now fading Mohist school! "

　　 After that, Mo Huai also bowed to Li Zexuan very sincerely!

These words are entirely his heartfelt words. Although Yanhuang Academy teaches engineering, its philosophy of saving the world is completely different from Mohism. At Yanhuang Academy and under Li Zexuan's command, the Mohist disciples can use what they have learned to practice. Xing Mozi's idea of ​​helping the world at the beginning can be regarded as a disguised way to carry forward Mohism!

　　 Without Li Zexuan’s strong financial support, it would be impossible for Mo Huai to participate in and complete such a huge project as the Bahe Dam that would benefit the people of one party!

　　 "Mr. Mo, please get up soon!"

Li Zexuan was so touched that he hurriedly helped Mo Huai up. He said with affectionate expression: "Mr. Mo is of noble character, dedicated to the people, and admiration for the far-reaching! The people of Lantian County will definitely appreciate Mr. Mo's dedication and great kindness! Alas! I’m not telling you anything. Just now, Daoist Li Chunfeng, the director of the Taishi Bureau, told me that he watched the stars at night and predicted that Datang would suffer a very serious drought, so Benhou was anxious to ask Mr. Mo to put down the dam gate. , Start storing water!"

　　 "What? Will there really be a major drought?"

Mo Huai's complexion changed and said, "No wonder that since the beginning of the year, there have been few rainy days. Mo believes that Li Shilang's prediction is very likely to be true. No, Mo will go and let the craftsmen and civilians continue. To speed up the progress, the Bahe dam must be filled as soon as possible! Otherwise, when it gets hot, there will be no water to store!"

　　 After that, Mo Huai arched his hands towards Li Zexuan and turned around and left.

　　............

　　 Palace, Temple of Ganlu.

Li Er walked up and down the hall with a gloomy expression, recalling what Li Chunfeng had just said, his brows were frowning deeper and deeper, and he sighed from time to time. Zhao Songjing in the hall was sullen and dared not make any movement. , For fear of disturbing Li Er who is in a bad mood now!

　　 "Punch!"

　　 At this moment, there was a sound of footsteps outside the hall. After a while, Empress Changsun was seen walking in with a few court ladies.

　　 "Your Majesty, the weather is very hot, and my concubine made an iced mung bean soup for you. Would you like to taste it?"

　　 Queen Changsun took the food tray from the maid behind her and walked to Li Er and said.

　　 Li Er waved his hand and said: "Kuanyin maid let go! I am not in the mood to eat now!"

　　 The empress of the eldest grandson looked stagnant, and she has been a husband and wife for so many years, how can she not see that Li Er is worrying now! She turned around and waved, and said, "You all go down!"

　　 "Yes! Mother!"

　　Everyone in the hall, including Zhao Song, all withdrew from the hall.

　　The Queen of Longsun stared at Li Er with both eyes, and asked softly: "Your Majesty has something troublesome?"

Li Er sighed, hesitated for a moment, and said: "Avalokitesvara's servant doesn't know something. Li Chunfeng from the Taishi Bureau just now came to me. He told me that Jupiter entered through the south gate of Taiweiyuan and exited from the east gate, and the Big Dipper was the seven stars. The bleakness and the floating light to cover up the evils indicate that there will be an unprecedented drought in our Datang! Moreover, he also told me that three days later, there will be a Tengu Eclipse Day!"

　　 "Great drought? Tengu eat day?"

Empress Changsun opened her mouth in surprise, and said in a panic: "Last year Yongan Hou Zeng told His Majesty that not only will there be a major drought this year, but there will also be a large locust plague, but as soon as there is a bad day, the people are afraid that there will be rumors. Are you all around?"

Li Er shook his head ~lightnovelpub.net~ and said: "I am not worried about rumors. Since I became the throne, I have always been diligent and caring for the people. The lives of the people of the Tang Dynasty have been significantly improved. There are rumors, how can I help? What worries me is that the drought is really coming! Last year, Li Zexuan’s prediction gave me a trace of luck, but now even Li Chunfeng said the same, then this year’s drought will definitely happen!

　　 At that time, after the severe drought, there will be another large locust plague, and the people in many parts of the Guanzhong land will have no harvest. My heart is very painful! If this is God’s punishment to Datang, I would rather bear it with all my strength than tens of thousands of people suffering from such a disaster! "

　　 "Your Majesty! Never! Never be so depressed!"

　　 The Queen of Longsun could not help but feel distressed when seeing Li Er frowning:

"Your Majesty, have you forgotten Yong'anhou? From last year’s chicken-raising reduction, to later urging the court fleet to go south to exchange food, and to the construction of the Bahe dam this year, he knew that there would be a severe drought in Datang this year. He has not given up with the locust plague, but he has always been fighting against the natural disasters! He is a fairy child, and with him, my concubine believes that I, Tang, will be able to survive this disaster, and I hope that your majesty will not worry too much! It hurt the dragon body!"

Li Eryi was startled, and then patted Empress Changsun on the shoulder, and said with emotion: "Yeah! Why did I forget that kid? With the granary full of Datang now, even if there is no harvest of the ground in Guanzhong, Datang can resist this. The next natural disaster! That kid is really a blessing bestowed on Datang from heaven!"
