The combination of wind and snow seems to be the eternal portrayal of the Northern Demon Plain, even in the spring when everything is recovering. The temperature of more than ten degrees below zero has made all human actions sluggish, and those who go out to work have wrapped themselves tightly in leather robes and cotton jackets, and are engaged in arduous walking in the ice and snow.

The cold day is rising, and the morning frost has not disappeared. Inside the Spindle Valley, it was a hot scene.

The shouts in the school field shook the sky, and the stimulated horse thieves gradually adapted to the arduous training rhythm, and every day they would move neatly and seriously to complete the tasks assigned by the instructor.

The young guards were divided into daily training and physical training. As the secret weapon in the hands of Sang Nan, they have always been training in a relatively closed environment, so the horse thieves don't know that many of these young men with undried milky and resolute faces are above them.

More than 30 slave laborers, plus more than 40 horse thieves and miscellaneous laborers, worked hard despite the bitter cold, and more than 100 newly built barracks were erected and scattered on both sides of the valley.

To his surprise, Sonnan discovered that these slave laborers had a wealth of expertise and design skills, and not only built these infrastructures beautifully. Many novel facilities have also been designed - such as bathing rooms and drying rooms.

The bathing room has a large space of 200 square meters, and several small enclosed baths are built inside, and the surface of the pool is made of stone with smooth surface and bright color. Twelve large boilers are installed in the room to melt the hot water while keeping it at room temperature, and the melted hot water is poured into the bath through fixed pipes.

Not only is the drying room warm and airy, but the walls are also covered with a creamy yellow Wacente ore, which is a natural desiccant that quickly absorbs moisture from the air and makes wet clothes dry quickly.

In a cold environment, laundry and bathing are extremely inconvenient. Cleverly conceived and rudimentary, these facilities quickly became a favourite among the girls.

Seeing the changes brought about by the slaves, Sang Nan was also secretly surprised in his heart, he paid attention to the observation, and soon locked on a target. This man, who was about thirty years old, was born with a good appearance and a strong force, and seemed to be the leader of this group of slave laborers.

Listening to Zhang Huan, this person's name is Ye Han, he is a native of Kasha Didu, his ancestors have been craftsmen for generations, and he has worked as a mason and carpenter. Moreover, they were all exiled after mistakes in the construction of the mausoleum.

When Ye Han saw Sang Nan, he knew that this unattractive child was actually the leader of this group of people.

"I called you here, I just think that you craftsmen are highly skilled and a little curious, so I want to ask the reason, you don't have to be nervous!" Sang Nan's tone was natural and said lightly.

"Yes!" Ye Han replied respectfully in a low voice.

"How can you, an ordinary craftsman, know Wacente ore?" Sang Nan asked a little strangely, he had read a lot of books since he was a child, and he rarely saw any records of ores. Ordinary craftsmen come from poor backgrounds, and young people learn art from teachers, how can they spend time learning these unpopular ore knowledge.

"Because, the villain used to be a master craftsman of three disciplines!" Ye Han's tone was a little lonely.

"Oh? You are a master craftsman of three disciplines! Which three subjects? Sang Nan couldn't help but be a little moved when he heard this. He knew that in the Moya Continent, craftsmen were an ancient profession, including carpenters, plasterers, blacksmiths, stonemasons, painters, boatmen, cooks, and dozens of other categories. According to the level of skill, it is usually divided into four levels: craftsman, craftsman, famous craftsman and god craftsman.

"Wood, iron, and stone!" Ye Han replied very simply. He spent most of his life researching inventions and was not very good at talking.

"Who is your teacher? Tell me, maybe I do! Sang Nan found that Ye Han's hands were rough and his joints were wide, which was obviously caused by frequent labor. But his words and deeds are polite, there is a degree of advance and retreat, and there is a hint of bookish anger between his eyebrows, which shows that he is not from a low background, he has seen a lot of the world, and he is not like an ordinary person.

"This-" Ye Han suddenly came to his senses, broke out in a cold sweat, and wondered if he should tell his life experience!

"Do you know that in this world, there are very few famous craftsmen in the three disciplines, and even less than the number of divine craftsmen?" Sang Nan was unimpressed by Ye Han's hesitation, because he had roughly guessed Ye Han's background.

During the Kasha Dynasty, the promotion of craftsmen was mainly determined by official master competitions. Sangnam not only knows about the Craftsman Competition, but even remembers the names of all the craftsmen for 500 years.

The Craftsman Contest is held every 10 years. Because of the large number of participants, it is divided into preliminaries and semi-finals. The preliminary rounds were held in the major principalities, and the semi-finals were held in the Kasha Imperial Capital. The official will set up different competitions according to the category of craftsmen. The top 10 in the preliminaries (single category) will become the single master of the category and qualify for the semi-finals. In this way, the Nine Duchy plus Kashya, there will be a hundred single Craftsman to participate in the semi-finals (single category) and compete for the title of Divine Craftsman.

In the end, the craftsman who won the first place is the single master craftsman of this year, and the craftsman from the second to the tenth place is the single master craftsman.

"All craftsmanship is passed down orally. Since you are a master craftsman in the three disciplines, then your master cannot be an ordinary craftsman. ”

Sang Nan ignored Ye Han, who was kneeling there and was stunned, talking eloquently.

"Kasha's Craftsman Contest has been held for 500 years, 42 times, and 4 sessions have been suspended due to the war, and a total of 587 craftsmen have appeared. As far as I know, among the 587 craftsmen, there are fifteen craftsmen in the second department, six in the third department, and only one in the fourth department. There are only three people who are likely to be alive now, and it just so happens that I remember their names. ”

Anyone who talks to Sang Nan will have a very strange feeling: he is obviously immature in appearance and innocent in his eyes, but he has mature manners and cunning methods, just like an old fox who has cultivated to perfection.

Ye Han's feeling was the same, the kid in front of him was thoughtful and a little too smart.

"If I'm not mistaken, you shouldn't have the surname Ye, but the surname Gongye, right?"

Sang Nan suddenly went straight to the point, his tone was a little cold, and the other party still hadn't told the truth, which made him lose his patience a little.

"That's right, my name is Gong Yehan! The father of the family is the master of the three gods. If you want to kill or chop, listen to it! ”

Ye Han's face suddenly became extremely pale, and he knew that he could no longer continue to hide it, so he simply admitted it happily.

"But why should I kill you?" Hearing Gong Yehan's words, Sang Nan was a little puzzled.

He lowered his head and frowned for a moment, then suddenly asked with a strange expression:

"What secret is there in the mausoleum?"
