Three days is very tight, how much is used for drawing drawings, how much is used for rough embryo shaping, and how much is used for fine polishing, all of which need to be planned as a whole.

If a certain link drags on for too long, it may lead to the final omission or even complete failure, which Xu Wen has had countless profound experiences in his previous work.

After determining the plan process, Xu Wen glanced at the sundial outside and filled the water leak at hand. Inside the copper kettle, the sound of water droplets ticked and the timer began.

Here comes the really hard part.

Xu Wen put down the pen, took the semi-finished wooden box next to him, observed it for a while, and began to disassemble it.

This treasure chest is connected by a mortise and tenon structure, with a detachable tenon and tenon, and it is not adhered to by a fish dart bubble, and Xu Wen can even disassemble it with his bare hands without using tools.

It's not difficult to take apart something, but it's not so easy to restore it.

Xu Wen used charcoal to make a mark on the surface of this part and write the number every time he took it apart.

This number was drawn up according to his own habits, and in addition to the order of the parts themselves, it also indicated the location where it was before it was dismantled, so as to facilitate future restoration.

This is the practice of contemporary cultural relics restorers that Ding Ling casually mentioned at the wine table last time, Xu Wen thought it was very interesting and learned it directly.

A good memory is not as good as a bad pen, even Tianqing is indeed amazingly strong, all the dismantled parts can be directly restored from memory, ordinary people like him, or honestly do what they should do better.

Soon, the semi-finished products of this treasure chest were dismantled into countless parts and placed neatly on the workbench one by one in order. At the same time, Xu Wen also drew more than a dozen simple flow charts on paper about the dismantling process just now, and after drawing them, the structure of the entire treasure chest had been basically established in his heart.

Next, Xu Wen began to measure the dimensions of each part and draw drawings based on it.

He could judge these dimensions with the naked eye alone, and the measurements were only further determined. Therefore, he made rapid progress in this step, the straight lines continued to extend on the paper, and the squares and arcs were constantly interlaced, and the length, angle, and slope were ...... Everything is made up of geometric shapes and is extremely standard.

He first finished drawing the existing parts, and then began to design the unfinished parts according to the existing foundations.

This part is theoretically more difficult, but Xu Wen designed it very smoothly without encountering any obstacles.

Geometry, in this case is invincible.

Just next door to Xu Wen, Wan Yongan, the head of last year's next mountain county, was holding a few wooden boards, his brows tightened.

When Xu Wen was writing the plan and drawing the drawings, he had already started construction and began to concoct wood and set the planks.

His basic skills are very solid, splitting and sawing, planing, and grinding, all the processes are very proficient, and the progress is extremely fast.

But he had a hard time filling in the two squares, and if he cut into the third square, it would clash with the previous part and get in the way.

He already had an alternative, so he changed to another one right now, and this one could coexist peacefully with the first two grids, but it was very unfriendly to the newcomer - when he made the fourth grid, he froze again.

Wan Yongan scratched his head vigorously, and after trying twice, he threw the planks on the table and complained, "What does this make people do!"

On the other hand, last year's Yongzhi County head Cai Kanshan's performance was completely different.

He made a small model out of a wooden plank, simulated the finished parts, and then continued to build the rest on top of that.

The planks are not carefully polished and are very rough, but they are good enough as a sample.

He cut them into various shapes and placed them in various positions at will, and he was very flexible and free.

Obviously, he had to decide on the structure he wanted to build on the model before he could start working on it.

With a smile on his lips, he acted calmly and did not look in a hurry at all.

Everyone's examination area was surrounded by curtains, but the sky was visible from the top, and there was no obstruction.

There is a high platform above the examination room, and from here you can see most of the examination area, especially the most advanced ones.

At this time, Sun Boran was holding a copper claireye, investigating the real-time situation of these candidates from afar.

Liu Xiu, the deputy chief examiner next to him, looked at the clairie and said with some envy: "Is this the Xuanwu clairvoyant given to you by the emperor? Legend has it that Xuanwu is lying on the ground, and the eyes are thousands of miles away, what does the emperor mean by this, does he praise you as a holy beast that protects the country?"

"He's an old man to reward things, and I'll just be a courtier, why do you want to do so much? Besides, what kind of holy beast or something, it's not the same as the turtle Wang Ba, is it nice to say that people are Wang Ba, why do you want to lead yourself?" Sun Boran said slowly, but Liu Xiu was startled.

"Xuanwu is a northern holy beast, but it is shaped like a giant tortoise, not a real tortoise, you misunderstood, misunderstood. Liu Xiu hurriedly explained.

"It looks like Wang Ba, and people think it's Wang Ba, even if you say it's not, what's the use?" Sun Boran's tone was still slow, Liu Xiu became more and more frightened, and was about to continue to explain, when Yun Yuanji next to him smiled and opened his mouth.

"Lord Sun is right, everyone is shining, and it is indeed difficult to explain. However, this clairvoyant seems to see farther than we are used to, is it more refined in craftsmanship?"

Sun Boran removed the clairvoyant eyes from his eyes, glanced at Yun Yuanji, and handed him the copper pipe in his hand: "It's really farther away, you can take a look." ”

Sun Boran's temper is notoriously eccentric, this time Liu Xiu and Yun Yuanji worked with him, and they only hurriedly met and said hello before the exam, and then they have been carefully touching his temper.

Now that the treatment of the two is completely different, Liu Xiu and Yun Yuanji glanced at each other, and they both had some calculations in their hearts.

Yun Yuanji remained silent, and after thanking him, he took the clairie and approached the eye.

He was really surprised by this.

Clairvoyance is also a telescope, and he has a good family, which is not a rare thing for him. But the one in front of him was markedly different from the ones he had used before.

Ordinary clairvoyants, who can see two to three times the distance, are already of relatively good quality. When it reaches three times, the field of view becomes very narrow and the light is very dark.

But Sun Boran is different.

With this claireye, you can see at least five times the distance, and the field of view is about three times as long, and the key is that the light is not dark at all and still appears very bright.

Yun Yuanji tried it out, put it down and took it to his eyes for a long time to observe, and asked suspiciously, "How did you do this?"

"Amazing, isn't it? This is the foreigner who paid tribute to the emperor last year, a total of four. The emperor rewarded me with this, and the remaining three were handed over to the Ministry of Industry to study and imitate, and they have not been copied until now. Sun Boran said in a light tone, not showing off, but looking a little worried.

Yun Yuanji's brows also furrowed, and he held it up in front of his eyes again and tried it.

Liu Xiu looked at it from the side, and asked tentatively, Sun Boran did not object, he hurriedly took it and tried it, and was also surprised: "This is also too far and too clear." How skilled are foreigners?"

Sun Boran didn't speak, sighed lightly after a while, and said, "Yes." ”
