Hearing the words "Treasure of the Town", Li Bing couldn't help but be slightly stunned. He turned his head to look at Shen Lie next to him, and Shen Lie also shook his head suspiciously, saying that he didn't know about it.

Li Bingxin said: With Xiahou Ninghan, Master Huidian and Shen Changshi here, I'm afraid that no assassin dares to come to spread wild, and the safety of the palace is definitely not in danger, so he ordered: "Xuanmi envoy to meet you." ”

The guards outside the door shouted yes, and then led an official in a dark court robe into the room.

When Li Bing and Shen Lie saw this person, they both felt a little surprised at the same time, they did know this secret envoy sent by the imperial court.

This person's name is Shang Yiyun, and the official worships the Qin Heavenly Supervisor, and is in charge of observing celestial phenomena, calculating solar terms, and formulating calendars. Shang Yiyun has been cultivating in Zhongnan Mountain for many years, so he is nicknamed "Shang Dao Chief" in the court. He is nearly seventy years old this year, and he is a veteran of the Three Saint Tang Dynasty, although his position is not high, but he is quite respected by the courtiers.

Li Bing saw that it was him, and couldn't help but say, "It turned out to be Shang Sitian, why did you come to Youzhou?" ”

Shang Yiyun first gave Li Bing a bow in a trembling manner, and then got up slowly and replied: "Your Highness, the old minister was ordered by the emperor to escort the national treasure to Youzhou and submit it to His Highness for custody. ”

"A national treasure? It's weird. Li Bing was a little surprised: "The palace was ordered to lead the army to resist the enemy and quell the rebellion, and the places where they are are all on the front line of the battlefield, what kind of treasure is the town of the country, which does not move to Xishu with the imperial court to avoid chaos, but is in a hurry to send it to the palace?" ”

Not only him, but everyone in the room had this question on their minds.

I only heard Shang Yiyun patiently explain: "Your Highness, you don't know something. This treasure was inherited by the Emperor Gaozu, the founder of my Holy Tang Dynasty, and it is called the Heavenly Observation Timing Instrument. It can not only calibrate the star position and observe the changes of the celestial solar terms, but also deduce the calendar through the operation of the internal organs, which can be described as a social instrument. What's more......"

Shang Yiyun paused slightly, and emphasized: "The old minister didn't know before, but the emperor personally told the old minister a few days ago that when this treasure was deduced to the first thousand years of the founding of the Holy Tang Dynasty, it would show a star map, and the mountains and rivers it corresponded to buried the huge treasure left by Emperor Gaozu. It is said that the treasures stored in it are all the treasures accumulated by the former dynasty Dujun who looted the world, and there are too many mountains of gold and silver to count. ”

Li Bing's eyes widened in surprise: "You're not joking, are you?" How could something so bizarre happen? ”

"The old minister is terrified!" Shang Yiyun was so frightened that he hurriedly knelt down: "No matter how bold the old minister is, he doesn't dare to joke about the national fortune and bully the king." This secret was told to the old minister by the emperor a few days ago, and there was absolutely no false tampering. It is precisely because of this that the emperor did not let the old minister move to Yizhou with the six departments of the three provinces, but after disguise, he escorted the Celestial Observation Chronometer to His Royal Highness. ”

The old man trembled and added: "The emperor hopes that the earth-shattering wealth can be left in the hands of His Royal Highness and used to reorganize my Holy Tang Jiangshan." ”

Seeing him like this, Li Bing hurriedly said: "Shang Sitian doesn't need to be nervous, this palace was also unintentional just now, and he didn't doubt your meaning." By the way, where is the armillary observation timer now? ”

"It's right outside in the car."

Li Bing instructed: "Okay, bring it in and let the palace have a look." ”

Shang Yiyun nodded when he heard this, and was about to give an order to his subordinates outside, when Shen Lie suddenly said on the side: "Wait!" Your Highness, before the treasure is moved in, please let Weichen inspect it first. ”

Li Bing knew that Shen Lie was cautious, because he was worried that there would be fraud in it, so he had to personally inspect the treasures brought by Shang Yiyun to make sure that they were safe.

So, he raised his hand and signaled to let Shen Lie take care of himself.

After about a meal, Shen Lie came back from outside, obviously having seen the so-called armillary observation timer, and there was nothing wrong with the treasure itself. Behind him were eight strong soldiers, carrying a five-foot-square copper utensil.

The appearance of the bronze vessel is spherical, and the spherical surface is densely engraved with constellations and symbols, which looks very mysterious and mysterious; On the periphery of the sphere, several graduated rail frames are mounted, which are staggered around the bronze.

Underneath the spherical bronze vessel is a square base, and vaguely, it can be seen that there is a complex mechanism lock inside, which is presumably used to deduce the astrological movement.

Perhaps because of the long-term relationship, the whole appliance, from the sphere above to the base below, is mottled with rust everywhere.

Shang Yiyun explained embarrassedly: "Please forgive your sins." The ministers didn't know that this treasure actually contained a shocking secret, and that it was just a tool for observing the stars like other ordinary armillary spheres, so they neglected to maintain it, causing this armillary observation and timing instrument to become like this. If the major events of the court are delayed because of rust and damage, then the old minister really deserves to die. ”

Li Bingxin said, presumably the previous emperors had already deduced and printed the treasure star map in the bronze, so that the armillary observation timing instrument would be handed over to Qin Tianjian for safekeeping, otherwise how could this treasure related to earth-shattering wealth be exposed to the sun and rain outside? It is estimated that Uncle Huang was afraid that he would send the map directly and that something unexpected would happen on the way, so he simply ordered Shang Yiyun to transport the original equipment directly to Youzhou, so that he could use the huge treasure to save the country.

In this way, this Shang Yiyun is worthy of being a veteran of the Three Dynasties who cultivated to the Tao. With such a tempting wealth, he did not abscond with the treasure on the way, but worked tirelessly and traveled long distances to faithfully fulfill his mission.

Thinking of this, Li Bing said happily: "Shang Aiqing, you have a meritorious role in protecting the treasure!" When you come to the Japanese palace to drive away enemies and pacify traitors, most of them rely on this treasure passed down from our ancestors! ”

Shang Yiyun was also very relieved: "Your Highness has killed the old minister." Being able to be loyal to the country is the glory of the old minister, how dare you call it a little credit. If you can share a little worry for the emperor and His Royal Highness, the old minister will die blindly. It's just ......"

"Just what?" Li Bing said curiously.

"Don't hide it from Your Highness, whether this armillary observation timing instrument can really deduce the treasure star map that has been produced for thousands of years, the old minister is not sure in his heart." Shang Yiyun said with a little worry: "After receiving the emperor's will, the old minister hurriedly went on the road, and he has not been specifically verified until today. ”

Li Bing nodded in understanding: "This palace understands." After all, the matter is very urgent, and the Turks are about to besiege the city, so you don't dare to delay the slightest. And along the way, it is already very difficult to avoid the eyes and ears of the rebels from all walks of life, and it is already very difficult to send the treasure to Youzhou intact and hand it over to the palace, so how can there be a chance to deduce? ”

Speaking of this, he thought for a moment, and then said, "It's better to do this, you can try to operate the treasure weapon here and demonstrate it to the main palace in person." ”

"This ......" Shang Yiyun hesitated: "Your Highness, such a confidential matter ......"

His meaning is very clear, the armillary observation of the time meter deduces the number of thousands of years, and the obtained mountain and river star map means a huge treasure, which is the most important secret of the Li royal family, there are many outsiders standing here, if it leaks out, wouldn't it be a big disaster?

Li Bing waved his hand indifferently: "It's okay!" This place is full of the most trusted and loyal people of this palace, and they will never covet treasures, and it doesn't hurt to see them with your own eyes. Besides, in the future, the star map will be deduced, and it will be up to them to move those gold and silver mountains back to the palace. ”

Shang Yiyun pondered for a moment when he heard this, and it was true, so he nodded and said, "What Your Highness said is true." Since this is the case, then the old minister deduced it on the spot here, and it can be regarded as the true completion of the holy order entrusted by the emperor. ”

As he spoke, he turned to Shen Lie and said, "Lord Shaoqing, if you deduce the calendar, you have to let my disciples come in to assist." ”

When Shen Lie went out to check just now, all his thoughts were spent on the armillary observation timer, but he didn't pay too much attention to Shang Yiyun's attachés. Now that I heard him say this, it was not good to go out and filter people again, so I had to say: "Since His Highness has a decree, then please ask Lord Shang to arrange it himself." ”

Shang Yiyun bowed slightly, and explained a few words to the guards next to him. The guards turned around and left as they said, and in a moment's effort, they brought in the twelve apprentices under Shang Yiyun.

Shen Lie raised his eyes and swept away, those guys who were both Shang Yiyun's apprentices and Qin Tianjian clerks, all dressed in black gauze robes and hoods, looked mysterious and unpredictable. He couldn't help but raise his vigilance, and slowly moved his body to a position close to Li Bing's body.

Almost at the same time as Shen Lie, Xiahou Ninghan also seemed to walk slowly in front of Li Bing seemingly inadvertently.

Shang Yiyun didn't pay attention to the actions of the two, and trembled and instructed his apprentice to arrange the surroundings of the armillary observation timing instrument according to the direction of the innate gossip, and prepare to start deducing the calendar.

Everyone moved quickly, some held the instrument mechanism, some checked the astrolabe with the flat end, some held the paper and pen used to record, and some stood in a solemn position to protect the Dharma, everyone was silent, quietly waiting for Shang Yiyun's instructions.

Shang Yiyun arched his hand to Li Bing: "Your Highness, the old minister is ready, please give an order." ”

Li Bing nodded: "Okay, then let's start." ”

With his words, Shang Yiyun's apprentices immediately pushed the mechanism of the armillary observation chronometer, and the copper sphere slowly rotated, and the surrounding scale tracks also flowed together.

The sphere rotates at a relatively fast speed, while the orbital scale changes gradually, methodically, gradually.

Several disciples in charge of observation kept their eyes on the astrolabe in their hands, carefully checking the evolution of the sphere and scale, and rhythmically reporting the star position data for the records of their peers.

"Seventy-one years of summer solstice, the day of the virtual day rat, four or five; Winged Fire Serpent, 19. Permit! ”

"At the end of the sixteen-fifth year, the horn of the wood Jiao, six or seven; Antares Moon Fox, Twenty-Eight. Permit! ”

"Three hundred and seventy-three years of the beginning of autumn, Kuisu Timber Wolf, one four; Pleiades day chicken, fifty-nine; Ghost Golden Goat, Sanliu. Permit! ”

"In the spring equinox of 708, the fire pig in the room, 33; Liusu Tu Deer, 27. Permit! ”

As the apprentices loudly reported the time of each year and the deduction of the star position, Shang Yiyun closed his eyes tightly, pinched his fingers with both hands, and said something in his mouth, as if he was silently calculating something. The star map that was a thousand years away from the founding of the Holy Tang Dynasty was getting closer and closer, and everyone present was unconsciously nervous, and the ministers and generals, including Li Bing, all focused their eyes on the constantly rotating chronometer, for fear of missing any detail, even Shen Lie couldn't help but be a little distracted, and from time to time he wanted to take a look at the changes in the scale of the instrument.

At this time, there was only one person in the entire room who was not attracted by the star map deduction.
