It is said that that night, Emperor Zhou Shun and Zhang Yucai, who were still alive at the time, were in the imperial study, and they talked from Hai Shi to Yin Shi, and finally because the early dynasty was about to begin, the exchange between the two came to an end temporarily. (10 p.m. to 5 a.m.)

As for what was specifically discussed, except for the imperial historian and the crown prince who were present at the time, no one else knew, and the relevant records of that night conversation were also sealed separately in the imperial treasury, which became a mystery.

What others knew, only in the morning of that day, Emperor Zhou Shun was repeatedly distracted, and his mind was not at all focused on the reports of the hundreds of officials in front of the palace.

After Zhang Yucai returned to the First Research Institute, he was not idle, but just a few days later, a hollow copper ball several feet high and a shelf made of fine iron were transported to the outside of the Taihe Palace.

As for Emperor Zhou Shun with hundreds of civil and military officials outside the palace, watching Zhang Yucai use pulleys to command a few ordinary people to lift the copper ball with a gentle pull, there are two sayings among the people.

One is that Emperor Zhou Shun just smiled slightly and nodded, and the civil and military officials around him also behaved lightly and steadily, showing the demeanor of the Great Xia court.

Another theory is that Emperor Zhou Shun's jaw was about to fall off at that time, and the civil and military officials around him were all straight-eyed, looking at everything in front of him blankly, and some even sat on the ground in surprise, which made people laugh and be generous.

But no matter what kind of statement it is, in the end, Zhang Yucai firmly fixed the copper ball on the fine iron shelf.

After that, together with Emperor Zhou Shun, he announced to the civil and military officials outside the palace that the land surveying and mapping and population census of the Great Xia Dynasty had been officially launched.

"In the future, the place engraved on this empty ball will be the land of my Great Xia!" This is Zhang Yucai's original words at that time, which was not only engraved on the floor tiles outside the gate of the Taihe Palace, but also engraved on the stone tablet next to a miniature version of the copper ball in the first research institute of the imperial capital.

Zhang Yucai did what he said, and he set up a surveying and mapping training class in the First Research Institute, and recruited scholars who were in good health but did not get into the examination to study.

The surveying and mapping training course lasted only a few months, and after that, they were sent to all parts of the country to carry out land surveying and mapping, while Zhang Yucai stayed, opened more training courses, and selected the best of them as teaching assistants.

Ten years have passed in a flash, the ball is densely engraved with the mountains and cities of the Great Xia Dynasty and various numbers, and the various products produced by the research institute are also extremely best-selling, with a high reputation among the people.

As a non-governmental institution, the first research institute of the imperial capital was in the limelight for a time, which was unprecedented since the founding of the Great Xia Dynasty, and Zhang Yucai, as the core figure of the research institute, was praised by the people of the imperial court as a peerless national scholar, and was called the reincarnation of a saint by the people, and some people even proposed to build a shrine for him.

But Zhang Yucai is not an ordinary person, after he noticed this situation, he did not have any nostalgia and decisively chose to leave.

However, this time, he did not say goodbye, but went to find Emperor Zhou Shun and explained his intentions, although Emperor Zhou Shun hoped that he could continue to stay and contribute to the early realization of the modernization of the Great Xia Dynasty, but he had already made up his mind, and there was no way, so he had to give him a gold medal in the end, which not only had the role of commanding hundreds of officials as if I was there in person, but also had the authority to mobilize any team of garrisons in the Great Xia under normal circumstances.

Zhang Yucai didn't plan to accept this gold medal at first, but after careful consideration, he still kept it, but he didn't take it with him, but stayed in the First Research Institute of the Imperial Capital.

At the same time, he also left three questions, and said to his right-hand disciples that if someone can really answer these three questions, he will give this gold medal to that person, and at the same time, that person will automatically take over the position of dean of the research institute, and tell him that as long as he walks east with the gold medal, he can find him.

As soon as the words fell, Zhang Yucai drifted away, and there was no trace between heaven and earth.

According to the description on the note left by Zhang Yucai, these three questions are a pair of upper couplets, half of a dialogue and eight poems that begin with the word "to".

There is only one requirement for answering, that is, it must be done in one go, without giving time to rest, and the answer is kept by the acting dean of the institute for generations, only if the previous question is answered correctly, the acting dean can open the following exercises and answers, and in order to ensure that there is a good order, everyone will register before answering, and within one year after failure, they are not allowed to answer the questions again.

As soon as this was announced, countless people tried it, and the registration books alone almost filled a room.

However, as expected, all the people who came to challenge were defeated by the first question, but there were still people who worked tirelessly to challenge.

At first, everyone praised them for their perseverance and perseverance, who knows, but later, it suddenly became something like that, "I can't even get the five-word pair right, and I dare to say that I am a big talent, I'm afraid I am a big fool" This kind of remarks made everyone feel very embarrassed, after all, no matter how good that thing is, you can't get it, don't say it, and there is still a foolish gaze in plain water, and gradually no one challenges anymore, and the heat drops again and again, and the three questions and the royal gold medal have gradually become the mascots of the first research institute of the imperial capital.

Although in principle, participants were not allowed to leak the question, but there were too many people who came to answer the first question, and it was eventually spread.

The first question is a piece of fine silk cloth nine inches long and six .3 inches wide, on which are written in the best blue ink the five words that have stumped countless talents.

"Odd and even unchanged"

"Poof!" Li Tao couldn't help it when he heard this, and the tea in his mouth squirted out again.

The heart said, this big brother can really play, and he wanted to complain, but he found that there were too many slots, which made Li Tao feel like he couldn't speak.

In other words, Li Tao really didn't expect that there was more than one traverser in this world, and that was the standard process of the protagonist, what is this, he is scolded by the system every day, and he is slapped and served if he disagrees, and he is not as comfortable as the days without the system.

"Ho ho, I didn't expect the host to be so angry. "The voice of the system may be late, but it will never be absent.

"Nonsense, I'm being by you like this every day, and you still expect me to be happy? Look at people, that's the protagonist!" As the saying goes, there is no comparison, there is no harm, after looking at other people's lives, and then looking at yourself, Li Tao was angry at that time, and went back directly.

"What's the matter, don't accept it, don't accept it, bear with it!" The system said indifferently, as if the more angry Li Tao was, the happier he became.

"......" Li Tao felt that his hand was about to move again, so he had to grit his teeth and swallow the words stuck in his throat into his stomach.

With Li Tao's interruption, Chang Wei also had to stop.

Chang Wei glanced at the sky outside the door with the corner of his eye, the sky at this time had completely darkened, and he had been talking for several hours in a row, and he didn't dare to drink water halfway, now he felt dry mouth, and even his voice was hoarse.

"Chang Wei. ”

"The little old man is here, what does the eldest young master command. ”

"Uh, you've worked hard today, and Young Master Ben has a reward. Li Tao saw Chang Wei's sluggish appearance, and he also felt that it was a bit too much for him to catch one and kill him like this, and he was determined to compensate him.

Li Tao beckoned, called Li Qiao to come closer, and didn't ask Chang Wei how much he could get in the afternoon, he opened his mouth to reward him with ten taels of silver, and all the money collected for the next month of the lecture was given to him.

And Chang Wei was overjoyed when he heard that he could actually get ten taels of silver, feeling that his throat was much more comfortable, and he could talk about it all night.

When Li Qiao, who was waiting, handed over ten taels of silver to him, Chang Wei bowed to Li Tao excitedly and thanked him for his support.

Who knew that the physical strength spent on the previous lecture was too much, coupled with the stimulation of the old age and the ten taels of silver, when I straightened up, I felt that my brain was dizzy, and my knees were weak, and I was about to fall to the ground.

Li Tao was also taken aback, there are few storytellers in Lijiazhuang, and if one is broken, it will be a great loss.

So Li Tao hurriedly stretched out his hands and held Chang Wei's arms, and Chang Wei was only a little dizzy for a moment, and soon he got better, looking up at Li Tao with grateful eyes, knowing in his heart that his old body, if he didn't have the hand of Li Shao's family master, I am afraid that if he didn't have to lie in bed for ten days and half a month, I am afraid that the ten taels of silver he just took would have to be explained to the pharmacy.

Li Tao picked up Chang Wei's body, looked at him with gratitude, reached out and picked up the silver that fell on the ground, and handed it back to him, and at the same time involuntarily reached out and patted Chang Wei's left arm, and smiled meaningfully.

After Li Tao explained to him that he would rest his body and that he would come back in a few days, he let Chang Wei leave with the silver.

Li Tao looked at the people who had been sitting in a sitting position for an afternoon, and wanted to laugh, but he still held back, looked at the sky outside, and felt that today's harvest was already very sufficient, and he could withdraw first, so he said hello to Li Qiao, declined his proposal to send someone to escort him, carried the small burden he was holding when he came, pretended not to hear the sound of a table behind him crooked chairs, and walked out of the door of the teahouse.

Different from the drowsy heat inside the teahouse, Li Tao felt that he was much more energetic when he was stirred by the cool night breeze, and took a deep breath of the cool moonlight, Li Tao felt that he was even more relaxed.

Li Tao walked along the road lit by street lamps, and at the same time couldn't help thinking in his heart, he was not the only one traverser in this world, and he didn't know whether this matter was good or bad for him.

Li Tao really thought about it, and suddenly felt that he had been hit, and then a figure rushed past him.

Li Tao was about to say that he ran so fast, was he in a hurry to go to the grave of the head of the family, but suddenly he felt as if something was wrong.

Look down and look at the empty hands.

There was only one thought left in Li Tao's mind.

"Lao Tzu was robbed !!"
