The emperor asked, and the tragic situation of the country's priest Jiu Zhouxun was ignored all of a sudden, and the atmosphere became unprecedentedly lively.

After all, such a group of young people from noble or official backgrounds, even if they are looking for fun, they avoid the scholars and officials on weekdays, and they have not been scolded for not learning and not knowing, and it is impossible to expect them to sympathize with Zhou Xun.

Especially Lu Sanlang, who is looked down upon all day long, was the first to shout: "Your Majesty, the minister dare not say that there must be a secret scroll hidden in this Taizu inscription, but the minister knows that Emperor Taizu is unfathomable and often takes precautions, it can be said that he is a rare saint since the beginning of the world, and it is possible for him to do anything!" ”

When Lu Sanlang opened his mouth, Zhang Chen also echoed for fear that the world would not be chaotic: "That's right, Emperor Taizu's deep meaning, how can mortals like me guess it!" ”

The representatives of these two gentlemen gave their opinions, and the others were naturally not far behind, scrambling to express their admiration for Taizu, and by the way, they quietly blackened the Guozijian.

For them, who have been resentful for many years, this is almost an instinctive choice, and even Zhu Er, under Zhu Ying's push, twisted and pinched the secret scroll of Taizu's inscription, maybe, probably, or...... Quite possibly!

Seeing that these prisoners from noble backgrounds fell into the well one by one, Luo Siye had the heart to help his own sacrificial wine lord exonerate, but he couldn't find a good reason, so he could only stand a little farther away and be anxious. As for Zhou Xun himself, the whole person trembled like chaff, there was no trace of blood on his face, and his lips trembled and he couldn't say a word.

In this chaotic noise, the emperor smiled at the corner of his mouth, but looked at Zhang Shou, who was silent on the side, and suddenly asked with interest: "Zhang Shou, why don't you speak?" ”

Zhang Shou said unhurriedly: "Back to the emperor, the minister is thinking, what material is the Taizu inscription plaque. ”

"Oh? Actually thinking about this? The Emperor raised his eyebrows thoughtfully.

"If I'm not mistaken, it's gloomy and wooden. It was sent to the capital by the magistrate as a treasure on a ship. According to the records of Taizu, the whole dozen gloomy woods, except for those parts like black charcoal, have a fine texture, as hard as copper and iron, and sink when they enter the water, so after the Guozijian is built, the plaques of the two halls of arithmetic and Gewu are made of gloomy wood. ”

"Emperor Taizu requires thickness, each inscription is very large, not to mention that it takes several people to carry it, and if you want to do it, it will not be enough, and the rest are leftovers. Now there are still a lot of hidden treasures in the inner library of the palace, and I only let people carve some small ornaments. Although gloomy wood is occasionally found in various places, it is rare to see such a good material. ”

"Moreover, it was sent all the way to the capital, and the people were wasted, and Emperor Taizu received things and applied for the vassals, so now no one has gone all the way to the capital to send this. Even so, there were still people who thought that the gloomy wood yin qi was too heavy, but Emperor Taizu said that the country's son was heavy and the yang was heavy, and the yin and yang were harmonized, so they blocked it back. ”

Seeing that Zhang Shou was still there frowning and pondering, he simply beckoned: "If you are curious, you can come and knock, this voice is very special." ”

Since the emperor opened his mouth, of course Zhang Shou would not be polite, and immediately stepped forward, squatted down and stretched out two fingers to knock on the edge and center of the inscription. Finding that it was indeed difficult to discern whether it was hollow or not, he pondered for a moment and then straightened up to face the emperor.

Before he could speak, the emperor had already asked with a smile: "I ask you, is there a way to distinguish whether there is a Taizu secret scroll in it without destroying this Taizu inscription?" ”

Zhu Ying was startled, and was about to open her mouth to push this tricky errand to Zhang Shou, but she didn't expect Zhang Shou to turn his head to look at her sideways and smile at her. Although she didn't speak, she couldn't help but have a thought in her heart that surprised even herself.

Zhang Shou really has a way?

"Your Majesty, can the minister ask this handyman who came out to rebuke Da Sicheng with two sentences?"

Seeing that the emperor waved his big hand and had a self-contained expression, Zhang Shou bowed down with a smile and thanked him, and then walked to the miscellaneous servant who was also kneeling on the ground. However, he was still three or four paces away from the person, but he stopped, and it was not until out of the corner of his eye that he caught a glimpse of Ah Liu's silent move to his side, and he was truly relieved.

There is no way, once you are shot by an arrow, everyone is an assassin...... You can't blame him for being overly suspicious!

He squatted down, looked at the handyman with a level-eyed gaze, and when he saw the person's expression of a single person, he asked with a pleasant face: "Since you said that Da Sicheng racked his brains to come up with the secret scroll in the inscription of Emperor Taizu, then how did you know?" ”

"I saw with my own eyes that the great priest went to the treasury of the country prison every day, and every time he would walk around the plaque, he was fascinated, and he often tapped with his fingers, and there were words in his mouth, and I once heard the two words of the secret scroll with my own ears!"

"Oh, then how do you know that there are a hundred secret scrolls?"

"In the past three years, Da Sicheng has sent people to collect a lot of barnyard official histories about Emperor Taizu, and they are all placed in the library of Guozijian. When I went to clean, I turned to a page that he had marked, and it was exactly one hundred articles of Taizu's secret scroll! And I snuck into the storeroom and knocked on the plaque! If it weren't for the fact that the middle part of the plaque was completely hollow and a large piece was missing, it wouldn't be impossible to hear when you knocked it! ”

The miscellaneous servant looked directly at Zhou Xun as he spoke, and said word by word: "If you don't believe me, you can ask the others in the Guozi Prison if Da Sicheng goes to the treasury every day if he is fine!" In addition to this plaque, there is nothing else in Guozijian's treasury, which is worth his visit every day! ”

As soon as these words came out, not to mention that Zhang Chen, Lu Sanlang and others suddenly realized one by one, even Luo Siye couldn't help but be a little surprised.

He has worked with Zhou Xun for more than three years, and to say that this Taizu inscription plaque was taken off by Zhou Xun, it is pure nonsense, but Zhou Xun always goes to the warehouse where this plaque is stored, and it is really there, he has seen it several times!

He inquired curiously, but Zhou Xun said that he admired Emperor Taizu's calligraphy, and he didn't pay attention to it when he thought about it.

Could it be that Zhou Xun didn't know where he had read too much of the history of the barnyard officials, so he actually believed the nonsense that this plaque contained a secret scroll?

The problem is that if you want to get out of the secret scroll, you must destroy this precious Taizu inscription, and what do you want to do?

This isn't one of those legendary books of gods and ghosts, with treasure maps or vaults in the plaques!

And the emperor also said with a smile: "I didn't expect to have such an inside story, Zhou Xun, what do you say?" ”

"Never, never!" Zhou Xun, who was ashamed and angry, seemed to have no idea how to defend himself at all, but just kowtowed with tears in his eyes, repeating these four pale and weak words.

And the emperor saw that Zhou Xun couldn't ask anything here, and Zhang Shou had already stood up and walked slowly towards him, so he asked with a smile: "Zhang Shou, you're done asking, what is the way?" ”

"Your Majesty, the minister has an idea."

With an affirmative tone, Zhang Shou said calmly: "If the emperor said that there is no longer the gloomy wood that made the inscription of Taizu back then, then the minister is naturally helpless, but since there are still many leftovers in the palace, then the minister has an idea." May I ask the emperor, those leftovers are added together, but they are as heavy as this Taizu inscription? ”

"Well...... the emperor hesitated slightly, and then looked at Chu Kuan.

Chu Kuan immediately smiled and said: "Those leftovers are a lot of big ones, although I haven't weighed them, but I look at the rough ones." It's just that the old and new Taicang certainly have a big scale for weighing grain, but to weigh the weight of such a plaque, and so on, to weigh the same weight of leftovers, I'm afraid it's not very accurate. ”

Zhang Shou nodded: "It doesn't matter if you can't say it." The story of Cao Chong's elephant in the Chronicles of the Three Kingdoms should have been heard with the emperor's erudition. ”

"Oh, that's nature." The Emperor laughed more and more.

Zhang Shou said calmly: "Since this plaque can only be lifted by several people, it is naturally difficult to weigh it accurately, since this is the case, then treat it as a giant elephant, put it into a special boat on the calm pool that is about the same length and width as the plaque, and mark it according to the draught position." Then remove the plaque and put in the gloomy wood scraps one by one until the draft is level with the notch. ”

"Since it is a small piece, it is relatively easy to accurately determine the amount of leftovers of the same weight."

The emperor couldn't help but bow slightly: "Well, that's good, so what's next?" ”

Zhang Shou glanced at the whispering in the compartment over there, obviously exchanging Cao Chong's allusion, so he continued.

Then, tie the Taizu inscription to a rope and sink it in a completely filled pool. If the plaque enters the water, there will be a corresponding water discharge. When the water surface is completely calm, pull the plaque out, and then note down the height of the water surface in the pool after the plaque is out of the water. Next, the pool is completely refilled and an equal weight of gloomy wood offcuts is wrapped in a fishing net and plunged into the water. ”

Next, the wood was fished out one by one to see if the water surface height was level with the previous plaque after drainage. If it is level, it naturally shows that there is no difference between the two, and the Taizu inscription is a solid ......"

This time, before he finished speaking, Lu Saburo had already suddenly realized.

"I see! If the next notch is obviously different from the previous one, it means that the same weight of things is different in size, and it is naturally the hollow of the inscription, which is hidden in the void! ”

Regarding Lu Sanlang's mathematical talent, Zhang Shou has always looked at it, and seeing that he reacted so quickly at this time, he nodded with a smile: "Yes, so you don't need to destroy the Taizu inscription, you can know whether it is hollow and whether there is a so-called secret scroll!" ”

In fact, such a large plaque, with this kind of pure perfect conditions can be achieved in the theoretical method, in fact, is not accurate, because the possibility of splashing is very high, the scoring accuracy is difficult to guarantee, and the center of gravity is not easy to say. What's more, two gloomy woods that seem to look the same may not have the same density, let alone a pile of leftovers that are likely to have different densities.

Therefore, using Cao Chong's method of weighing the elephant and combining it with Archimedes' law is to measure the excitement.

However, the Emperor's attitude was very suspicious, so he suspected that the Son of Heaven only wanted to hear a solution, and he didn't really care much about the final results......

And Zhu Er, who was squeezed to the back by Zhang Chen and others, couldn't close his mouth open. It's already amazing that Zhang Shou can come up with a way, but how can Lu Saburo understand it so quickly? Isn't he just like himself?
