Zhang Qian and others stayed in Yangcheng for twenty-three days, during which time, he and the technical officials of Si Tianjian recalibrated the new sun and the sun, successfully accurate the prediction of the lunar eclipse to within a quarter of an hour, and by the way, also re-calibrated the latitude of Yangcheng, and officially determined the concept of a circumference of 360 degrees.

Although the first few tasks took some time, the results were easily accepted by everyone because the observation targets were very direct. However, the latter two "incidental" products, convincing Si Tianjian's technocrats to accept, made Zhang Qian spend a lot of effort.

The reason is simple, the mathematical concepts of people in this era are completely derived from the observation of the natural world. In the relative motion of the earth and the sun, the earth is regarded as a stationary point, and the sun rotates the earth. The whole year is three hundred and sixty-five and a quarter of a day, and the position of the celestial sun on the ecliptic changes every day, just marked by one degree.

Therefore, the ancients believed that the Zhou Tian was 365 degrees and a quarter of a round. The circumference of the Tianzhu monk is 360 degrees, which is a fallacy and heresy. (Note: The concept of 360 degrees is actually a mathematical concept.) And three hundred and sixty-five and a quarter are observations. ）

Although Zhang Qian's position is higher than that of those seventh- and eighth-grade technocrats, and his qualifications and prestige are not enough to force others to accept his theory. It is even more impossible to prove with actual observations that the Earth's orbit is an ellipse, not a pure circle. So, in the beginning, he was extremely big-headed. However, when he introduced trigonometric functions into his calculations, all the problems were solved.

In any era, scientific and technological workers are the most serious group of people. However, when they discover a new concept or technology that can bring great convenience, they are often the least stubborn. After trying to recalculate some astronomical observations using the trigonometric function theory that Zhang Qian came up with, the technical officials of Si Tianjian were quickly conquered by this theory. As a result, the difference between Zhou Tian and Yuanzhou was automatically "understood" by the officials.

Such a strong flexibility made Zhang Qian, a traverser, admire him so much that he gave a thumbs up.

According to the comprehension of the officials of the Si Tian Supervisor, one and a half of the three hundred and sixty-five degrees of Zhou Tian is natural, almost like the Tao, and there is no mistake. However, the concept of a circle is artificial. What is set by man is destined to fail to achieve the perfection of nature, so the circumference of the calibration is three hundred and sixty.

Thus, the circumference of the circle is 360 degrees, and the sum of the inner angles of the triangle is exactly 180 degrees. In this way, calculating the shadow of the sun, the distance between the stars, and the star difference are all twice the result with half the effort!

Therefore, the officials present unanimously decided to use the two nominations of 365 degrees and a quarter and 360 degrees for the ecliptic of the sun at the same time, as a sign of respect for the heavens. In the future, in various other astronomical calculations and observations, everyone will resolutely move closer to the 360-degree calibration method. (Note: During the Kaiyuan period, the monk and his entourage also did this when formulating the Great Yan Calendar.) It is claimed that the Zhou Tian is three hundred and sixty-five, and the actual calculation of the Moon Huang Wei is three hundred and sixty)

This change has led to a rapid revision of the calendar. There are many deviations in the "Lin De Calendar", which can be directly corrected by changing the degree of circumference. The revised results, if not identical, from the Purple Gold Calendar, are tolerable. In this way, the theory of the Book of Changes, which is used to explain the "Lin De Calendar", can be directly applied to the "Zijin Calendar". The deviation between the two calendars can only be regarded as differences in calculation parameters and observation accuracy, but the "guiding theory" can be regarded as completely consistent.

In this way, the service life of the "Lin De Calendar" can be greatly extended. The pace of revision of the New Calendar can also be greatly accelerated. After all, on the basis of the research of predecessors, the workload of excellence is much smaller than starting from scratch.

As the organizer of this astronomical calculation mission, Zhang Qian did not personally participate in most of the actual work. However, his prestige among the technical officials of Si Tianjian is increasing day by day. Especially when everyone advanced the accuracy of the lunar eclipse prediction to within a quarter of an hour for the first time according to his instructions, many technical officials with white hair respected him as much as the teacher.

A boss who understands technology, does not interfere indiscriminately, and respects the opinions of his subordinates is worthy of respect in any time and space. What's more, in addition to these three advantages, Zhang Shaojian also knows how to cherish the lives of his subordinates.

Sensing that he might encounter an interception, he immediately made an excuse to let everyone cross the river a day late, and he took his family and measuring instruments to explore the way.

As for whether those thieves were pretending to be government soldiers and who was behind them, he didn't say a word to everyone. Obviously, he didn't want to drag everyone into the whirlpool and suffer from the pond fish.

Even technocrats are not all ignorant of human feelings.

Finding that Zhang Qian deliberately separated everyone from the vortex he was facing, the officials of the Heavenly Prison were grateful, and they all worked harder. As a result, the work, which was expected to take a whole month to complete, was completed in just twenty-three days. And every step of the observation data and calculation process is organized extremely cleanly.

For the entire twenty-three days before and after, Zhang Qian did not leave Yangcheng for half a step. Daily life is extremely regular, the observatory outside the city and the post station in the city, two points and one line. The officials of Yangcheng County and Si Tianjian can all testify for him.

However, in these twenty-three days, three White Horse Temples were slaughtered, two White Horse Temples were burned to the ground, and one White Horse Temple monks killed the abbot and divided all the gold, silver and copper coins in the temple, and then disappeared.

During this period, there was also a small group of "thieves" who did not know where they came from, and it is said that they tried to sneak attack the observatory because they spied on the bronze utensils on the observatory. As a result, more than 100 Shuo Fang troops who were ambushed around the stargazing platform were killed.

The battle was far from fierce, no one from the Shuo army was killed, and the total casualties of the Ren and Guo families together did not exceed twenty. The total number of casualties of the "thieves" defeated by them was only about 70, and the rest all took advantage of the cover of night and the jungle to escape.

However, the shock that the battle brought to the surrounding forces is difficult to describe in words. The day after the battle, Yu Jin, the military governor of Zezhou, recalled all the officers above the brigade command to the barracks. Strictly order no one to go out, otherwise military law will punish him.

The military governors of several neighboring states soon took similar actions. lest any more low-level officers be tempted by money and run to the stargazing platform in Yangcheng to find death.

For those who refuse to listen to persuasion, have to find death, and drag everyone down. The governors of the prefecture also took resolute measures at the risk of offending a certain imperial relative. Anyway, it's easy to kill someone these days, and as long as you deny it later, that royal relative will naturally settle the account on Zhang Qian's head.

And the bandits and grass bandits who were within the range of the Yangcheng War Horse could arrive in one day decided to move, so as not to let the young eunuch Zhang on the stargazing platform retaliate indiscriminately and let themselves suffer from the pond fish.

People in the rivers and lakes have to be face-saving, even if they take the initiative to run away, they have to find enough reasons for themselves. Fu Yuan, the boss of the calf village, is such a person. As soon as the front foot left the cottage, he began to muttered to the cronies around him on the back foot, "It's not that we're afraid of the surname Zhang, but there is no need to wade into this pool." Do it with him, win or lose, and get the cheap ones are the bald donkeys of the White Horse Sect. We are not Baiwangzhai, and we have never had anything to do with bald donkeys. At this juncture, there is no need to prevent disasters for others! ”

"The big boss is right, let's talk about the surname Zhang, and the well water does not interfere with the river water. He wants to seek revenge on others, so we don't need to stand in the way! Immediately, a minion stepped forward and echoed loudly. It's as if you can change the tide of the battle as long as you make a move on your side.

"Isn't it? We have no grievances with the surname Zhang, and there is no need to block the knife for the bald donkey of the White Horse Temple. The white boss of Baiwangzhai just couldn't figure it out, and as a result, he gave away his own life, so big a dreadlock, and he was defeated all of a sudden! Some people are more practical, looking back at the cottage that has gradually been thrown away, and muttering tremblingly.

"If you want to say that white boss, you really didn't die unjustly. I don't look at how many pounds and taels I have, and I actually provoke a demon who knows how to spell! As a result, the other party casually recited a mantra, and all the entourages around him were invulnerable. Not only did he take his own life, but he also took the entire Baiwang Village to accompany the funeral! Immediately, someone whispered in favor of the rumors, as if he had stood beside Boss Bai and witnessed the entire battle.

As soon as the conversation box is opened, the topic will be crooked at any time. In the blink of an eye, the focus of the discussion among the thieves was no longer why they ran away, but what happened to the surrounding colleagues in the previous paragraph.

"But isn't it, the surnamed Bai only saw the money given to him by the monk, and he didn't inquire, that young eunuch Zhang couldn't afford to provoke him!"

"Alas, Boss Bai died of lack of knowledge, and that Zhang Qian is not an ordinary person. His title of secretary and young eunuch is actually more appropriate to be called a young eunuch of secret arts. Taking advantage of the solar eclipse a few years ago, he attracted a meteor, and with a "boom", the group of monks who blocked the door to challenge him were wiped out along with the altar! ”

"It is said that Buddhism is boundless, but so many monks were destroyed by Zhang Motou alone. Who gets more mana, do you need to ask again? ”

"Ah, I know how Zuo Saburo died." Someone raised his hand to hold his forehead and shouted, "Lunar eclipse, there was a lunar eclipse the night before yesterday!" During the solar eclipse, Zhang Shaojian can cast a spell to summon a fire meteor, isn't it the same for a lunar eclipse? ”

The topic went off the rails again, from Baiwangzhai, and in a blink of an eye, it ran to a certain captain of the government army who pretended to be a bandit.

"He died even more unjustly! Relying on himself to be a government military captain, I don't know how many innocent people have been harmed over the years. This time it's a lot of evil. ”

"He's dying on a crazy word. From the end of last month to the middle of this month, how many people did the White Horse Sect ask for help. Everyone else knows that the surname Zhang can't be provoked, but he wants to rush to find death! ”

"Isn't it, you don't pick a place to die. actually pretended to be our green forest heroes and went to attack the stargazing platform. Is the stargazing platform easy to sneak attack? That young eunuch is Li Chunfeng's descendant, and he knows the good and bad by stargazing. I estimated that he had already calculated the day of his surname Zuo through stargazing, and then started to step on the fight in advance! (Note: Bugang stepping on the bucket, the ritual of Taoist practice.) ）

"Do you still use the step gang bucket method? It is enough to know astrology! didn't wait for the fight, and the bottom of the surname Zuo was all seen by him. Next, how can he die if he wants the surname Zuo, and how can he die if the surname Zuo is not right?! ”

"Hey, don't talk about this, let's go, panic!"

"It's panicking. Anyway, I'm not going to provoke these spells. I don't want to give any amount of money! ”

"Of the, the, theirs, the......"

Just as they were talking, behind everyone, there was a violent sound of horses' hooves. When they landed, everyone was so frightened that they immediately spread their legs and ran away.

Fu Yuan, the big boss of Niutouzhai, has a horse, and he naturally runs faster than his minions. He ran for forty miles in one breath, and it was not until the mouth of the war horse under his crotch spit out white foam that he had to pull the reins of the horse, and lay on the horse's neck to "return to breath".

"Of, of, of, of......" Before he could take a breath, the sound of horses' hooves was heard behind him. When he boarded, Fu Yuan was so frightened that his eyelids rolled and he fell off the horse softly.

"Fu Da is in charge, it's me, the little sixth son, the little sixth son of Wangjiazhuang!" Very fortunately, it was not the officers and soldiers who caught up, but the sons of friends who had been friends with him for many years. The latter saw that he was so frightened that he was almost paralyzed on the ground, and he was angry and funny. With two henchmen Zhuang Ding, he flew off the horse to support him, and quickly added, "My grandfather said that the surname Zhang is gone, and he left early this morning." It's okay, you don't have to hide. Hurry back, he wants to discuss with you how to respond to Luo Daxia's hero post! ”

"Gone, who do you say is gone, Young Eunuch Zhang? That young eunuch Zhang on the stargazing platform? In an instant, the soul of Fu Yuan, the big boss of Niutouzhai, returned to his body, trying to stand firm and ask questions quickly.

"Who's not that scourge?" Wang Xiaoliu didn't think about it, and immediately gave a positive answer. "Not only are we looking forward to him leaving, but the officials of Yangcheng County are also looking forward to him getting out of the way as soon as possible. Therefore, he received the holy decree to return to Chang'an on the front foot, and the news spread throughout the city. ”

"Holy decree, you mean that the emperor has decreed that he has been recalled to Chang'an?" Fu Yuanleng, for the first time in his life, felt that Emperor Ying Tianshenlong was so wise and powerful.

"If it's not the emperor, who else can control that evil star? The eunuch who passed the decree, many people saw it. Obediently, he really didn't have a long beard, and his face was round like a duck's egg. It's just that the way I walk is very weird, and I like the orchid finger at every turn! ”

"It can't be a fraud, right?"

"No, after my grandfather got the news, he immediately sent someone to follow behind his back. It wasn't until his men and horses left the county border that they came back to report the news. ”

………………

"Li Xian is in such a hurry to call you back, what is it for?" Riding on a captured Dawan good horse, followed by another horse, Luo Huaizu hurried while leaning his head to Zhang Qian's side to get to the bottom of it.

To tell the truth, he was one hundred and twenty unwilling to let Zhang Qian return to Chang'an so soon. How good it is to stay in Yangcheng, the mountain is high and the emperor is far away. Even the official rank of Zezhou Thorn History is one level shorter than Zhang Qian. No one could control the head of the team that spent money to revise the calendar, and the local government had to ensure the daily supply of the team.

And he, the head of Luo, wanted to follow Zhang Qian's side as the second account room, so he acted as the second account room. If you want to go out to be Luo Daxia, go out and be Luo Daxia. Never worry about revealing your identity. Even if they are in trouble, as long as they hide within the range of the observatory, no force will dare to continue to follow them.

In addition, the recent period of time is also the day when he has made the most money in charge of Luo. Although Zhang Qian had repeatedly demanded that once the attack on the White Horse Temple was successful, he would scatter the floating wealth in the temple as much as possible to attract more people from the rivers and lakes to attack other White Horse Temples. However, he was not forbidden to enrich himself.

Therefore, when he saw the "floating wealth" that was particularly valuable and easy to carry, such as gold, precious stones, etc., Luo Huaizu grabbed a few handfuls. As a result, he couldn't carry his bags anymore, so he could only free up a horse to camel.

"I don't know what he's looking for me, it's very vague in the decree. Regardless of whether there is any progress in the revision, I will return to Chang'an immediately. Zhang Qian glanced around with a telescope and replied very absent-mindedly. Anyway, the mission has been completed, so let's go back. If you stay on the stargazing platform, no one will come to die. ”

"Won't it be to trick you back to Chang'an first, and then arrest and take you to prison, and vent your anger for the bald donkeys of the White Horse Sect?!" has never been afraid to speculate on Li Xian with the most evil malice, Luo Huaizu frowned and reminded.

"That's not going to happen, since the Holy Lord can't hold me accountable for the White Horse Sect and those behind the White Horse Sect, naturally he can't hold me accountable." Zhang Qian still knew a little bit about Li Xian's personality, smiled and shook his head slightly. "Besides, no matter how much I take revenge on the White Horse Sect, it will not be harmful to the imperial court and the Holy Lord himself. It could even be very advantageous! ”

"Then you still ......" Luo Huaizu quickly looked around to make sure that no one was eavesdropping, and lowered his voice to propose, "Then you still call him a saint?" Where does he have the appearance of half a saint? Neither courage nor responsibility. You will hide and make tricks to calculate others, even if you have made great contributions to the country, as long as you make him feel threatened......"

"He may not be a saint, but he treats me well." He had long been wary of Luo Huaizu fooling himself into following in the footsteps of Zijuan's father, and Zhang Qian interrupted without hesitation. "In addition, I don't like rebellion, and I'm not interested in reviving the lintel of the Mo family. So, there are some things that Hugh has to mention again! ”

"You ......" Luo Huaizu prepared a stomachful of rhetoric, but he didn't get a chance to state it, and his face suddenly turned a little blue. Gritting his teeth and gasping for breath for a while, he regained his spirits and continued to whisper: "I am not advising you to rebel, you are greedy for wealth and enjoyment, that kind of risky thing is indeed inappropriate for you. But the people who want to murder you, one is Li Xian's biological daughter, and the other is his own sister, as long as he refuses to come forward to administer justice for you, you will never want to live in peace for the rest of your life. ”

"Then come on, anyway, I'll take revenge." Zhang Qian smiled slightly, and his young face was suddenly full of confidence. "To be honest, what I'm more afraid of than being an enemy is getting too close to the two of them."

This sentence suddenly exceeded Luo Huaizu's comprehension. I couldn't help but keep my head down and think hard. However, his head hurts, and this person didn't understand where Zhang Qian's confidence came from. couldn't help but stare at his bloodshot eyes, and asked in a low voice, "Do you know how to watch the stars and fortune?" Or the secret technique of the Ghost Valley, can you predict that these two people will not end well? ”

"I won't!" Zhang Qian didn't even think about it, and decisively denied it, ""Non-Life" is a compulsory chapter of the Mo family, has Uncle Shi forgotten it? ”

"Fate" is one of the famous stories of Mo Zhai, the patriarch of the Mo family, as the real head of Qi Mo, Luo Huaizu is of course impossible to forget. However, seeing that Zhang Qian suddenly used Master Zu's writings to deny that he knew astrology and divination, he felt that he might have guessed the truth. So, he frowned and said in a low voice: "The purpose of what the ancestor did is to teach the world to forge ahead, and I don't believe that fate is destined to be noble and low." Rather than denying astrological divination. You Qin Mo have been in hiding from the world for many years, without war, and left some inheritances from other families, which should also be ......"

"I really don't and don't believe in that!" Zhang Qian was most afraid of being treated as a god stick, and interrupted without hesitation.

"Then how did you calculate that on the fifteenth day of this month, someone would disguise himself as a bandit and sneak attack the stargazing platform?" Luo Huaizu still didn't believe his words, grabbed a specific case, and got to the bottom of it.

This question is very easy to explain, Zhang Qian smiled and gave an answer unhurriedly, "The White Horse Sect is just a gang of loan sharks, not robbers. After the first failed attempt, it will definitely take time to gather another man. And the purpose of my verification is to verify the new sun, the sun and the lunar eclipse, even if there is no holy decree to summon me, after the task is completed, I will definitely have to return to Chang'an. In the land of Gyeonggi, it is estimated that no one has the courage to pretend to be robbers to intercept and kill officials. So, they had to do it before I left Hedong. In contrast, the bandits either don't come, or if they do, it must not be too late. Moreover, there are a lot of night blindness in this year, and if you want to lead the people and horses to attack at night, you can only choose the days when the moonlight is the brightest! ”

"Well......" Luo Huaizu still didn't want to believe it, however, he found that Zhang Qian's answer was almost impeccable. After pondering for a long time, he quickly turned the topic to the next place where he had always felt confused, "That copy of the "Purple Gold Calendar" was taken out by you from the teacher. Since you know that it must be accurate, why do you have to go to Yang City? Isn't it the same when someone is sent? The old man always felt that you knew in advance that someone would intercept you, so he deliberately ran out to be a bait. If you don't know astrology, how can you guess so accurately? You've only been an official for a few days, so you definitely don't have this kind of ability. And Zhang Shanchang and He Zhizhang, the two of them are playing tricks, I'm afraid they are not as good as you. ”

"This ......" Zhang Qian's eyes quickly flashed Yang Qi's old but wise face. Shaking his head, he replied with a smile, "You better let me know astrology." Li Chunfeng's "Delin Calendar" has so many mistakes, and they all claim to know everything for two thousand years. The "Purple Gold Calendar" I took out was several times more accurate than the "Lin De Calendar", and I must know more than him. ”
