When Gencheng saw that Yu Xue was sitting down, he slowly explained his thoughts to Yu Xue as if he wanted to pour beans.

Moreover, for the origin, shape and color of each kind of gold and stone, there are methods of mining and identification, and the wellhead is only as big as a small bowl, but there are dozens of zhang deep.

Use thick bamboo to make a well sleeve to cut off fresh water. Use relatively small bamboo to make buckets, go in and out of the well, fill several buckets of water in a tube, and lift them with machinery.

I don't know why the emperor let him use purple, I remember that it was the first time he wore purple when he went to the lotus picking festival, and it was Sima Jing who said that the color was too heavy. At that time, the emperor was still Tao Gongzi, and in order to make a living, he dressed up as a maid to send love notes to other girls.

Don't tighten too much each time, it's best to tighten one inch at a time. When the full bow opening that is suitable for the archer is reached, the bow is tamed.

Moreover, if it is said that there are green onions in the mountains, there is silver below, and the light is faintly white.

On the one hand, he felt guilty for his poor consideration, and secondly, someone was injured, as the emperor, but now there is only Si Kui, the imperial doctor, in the palace, and for his safety, Yi Xue does not plan to let him out of the palace.

Mercury or gold ore is dominated by placer ore. In placer deposits where mercury and gold coexist, it is more accurate.

Asking about the new mine at the Qiuli banquet is generally a mixed blessing, but even if you know the way, you must also have someone who can go to the local area to do practical things, in addition, the existing government-run mineral deposits also need to go to the local area to confirm the situation.

Yi Xue didn't expect him to have no sneers today, looking at his comfortable appearance, and after a while, he also lay down on the side, looking at the sky.

He promised that as long as he went to the appointment, if Yixue stopped paying attention to him in the future, he would not bother her again.

It's tonight, if you don't succeed, you will lose.

A light and a shadow disappeared at the end.

Xue Xue was cautious, and just walked over and stood silently behind him.

Yi Xue was confused by Yuan Cheng's overly intimate behavior today, in fact, she was secretly happy in her heart, but she was angry at why she was happy, obviously she already felt that she had let go, but she was disturbed by his every move.

Seeing Yuan Cheng leading the horse over, he began to regret why he agreed to him, thinking that he was pulled by Yuan Cheng to ride a horse before, his leg hurt so much that he couldn't do it, and that limping appearance must have been laughed at by Yuan Cheng for a long time.

But I found it more comfortable when I sat on it today, maybe just because I was used to it. And the last sentence that Yuan Cheng said, what is that! Be all abroad!

When he arrived at Bega Lake, Yuan Cheng let the two horses go to graze, and he sat directly next to Bega Lake, leaving a place for Yi Xue, and motioning for her to sit down, that position is where Yuan Cheng often sits, the grass has collapsed, and it will not prick people.

Treat talents with courtesy like Zhou Gong and reuse it for this.

The raw material should be a straight part of the middle of the trunk, with a uniform texture, and no or as few knots as possible. Cut off most of the sapwood from the log to obtain a cross-sectional square and as long as a shooter.

The orange fragrance was on Yuan Cheng's body, she was knocked unconscious and taken out of the palace when she was a child, and she smelled the same smell, that person was Yuan Cheng when she was young.

Then there is the Lotus Picking Festival, and he was tricked into approaching him in order to send a love note, and then awakened the taste in his memory. Later, in order to deceive Sima Lie, Yuan Cheng rode her back to Beijing overnight, and she also smelled the orange fragrance, and the two of them were very close.

Refers to the maximum opening that the archer can pull out, which is equivalent to the distance from the palm to the chest when the arm is stretched out. At this time, remove the bracket and brush the arch back with several layers of linseed oil as a moisture protection layer.

Later, during the Mid-Autumn Festival, Yixue was drunk and was picked up by Yuan Cheng without standing firmly, and she smelled the orange fragrance again, although she had no memory, but she remembered the smell.

After ascending the throne, the steps were whipped three times, and under the command of the praise officer, the ministers knelt three times and bowed nine times. During the ceremony, the hundred officials saluted and played the great music of His Majesty, but at this time, it was not done, and the congratulatory text of the ministers was not announced.

Later, Yuan Cheng taught her archery in the school field, and wrapped her in his arms by sticking to her back, the faint smell of sweat was still mixed with the fragrance of orange, which was Yuan Cheng's own taste.

The process of bending is called "taming the bow", which is to allow the bow back to gradually adapt to the bending. To do this, you need a special bracket. The bracket can be made of hardwood, with a groove dug vertically at one end to support the bow, and the other end managed to be fixed vertically to the ground.

And after the big shooting, he was poisoned and fainted, it was the first time that he was picked up by Yuan Cheng in memory, the embrace of the smell of oranges, and the Wulan banquet, New Year's Day, birthday, Tanabata Festival, etc., this taste made up a beautiful dream for the snow, a dream that will eventually dissipate with the wind.

From the cross-sectional point of view, it is necessary to take the middle part, half of which is the wood core and half is the sapwood.

The core is relatively soft and compression-resistant, and is placed on the inside, while the hard tensile sapwood is used on the outside. This can be judged by looking at the wood grain in the cross-section, with the relatively sparse side being the outside.

Thinking of this, Yi Xue couldn't help but burst into tears, and she quickly wiped away her tears in a panic, not wanting to be discovered by Yuan Cheng.

Although these may not be completely consistent with reality, the direction of prospecting using indicator plants is correct, linking the underground deposits with the surface plants.

A certain mineral that appears on the mountain and another mineral that appears below the mountain are produced in different strata or rocks, and they are not the same ore body, which is only a relative relationship in location.

Because it is difficult to be completely uniform with naturally grown wood, there may be some places that are harder, some places are softer, and the strength may not be the same just because the shape is uniform.

Yi Xue and Yuan Cheng had a cold war, Yuan Cheng thought that she was unhappy because he didn't intercede with the emperor for her yesterday, and wanted to explain to her, so this morning he asked his father to mention the friendship of Ulan in the court, and asked the emperor to forgive her, so he took the initiative to invite her to go to the grassland to see the stars at night the day after tomorrow.

Therefore, it is necessary to correct it by observation and make the hardness slightly thinner. The dorsal aspect of the arch is darker, and the medial aspect is slightly lighter.

The white pigment may be a flux-infused china clay made from natural calcium carbonate minerals combined with clay. This lime glaze is the ancestor of celadon glaze in later generations.

Celadon glaze is formulated from limestone and porcelain clay. In lime glaze, iron is the main colouring element, followed by titanium and manganese.

At this time, it is necessary to carefully check whether the curve of the bow is smooth and even, mark the areas that are too stiff, relax the bow back and trim and fine-tune until you are satisfied.

I don't know how long it took, the night came, and the bright moon slowly climbed into the sky. Yi Xue was tired of standing, and seeing that Yuan Cheng didn't want to be as aggressive as usual, he quietly did it beside him.

When the oil is dry, you can hang the strings. The bowstring is made of sheep intestines or tendon tanning, and the elasticity and toughness are very good. The fixed opening when hanging the string is controlled by the distance between the bowstring and the center of the bow back to reach the height of the fist.

Every three or four chord grooves are added, and the rope can be tightened. This process should not be rushed, especially before each increase in the opening, it is best to let the arch back "rest" so that the internal stresses can be relieved to avoid damage to the wood.

Yi Xue was surprised by Yuan Cheng's sudden gentle tone, and originally showed a hint of sweetness, but when she suddenly thought that he might also say this to Su Yuqi, Yi Xue's face instantly turned cold.
