[You have learned the primary forging technique: refining metals, do you use skills?].

Li Mu silently confirmed that just like when smelting ore, his body moved involuntarily, and his movements were basically the same. He used iron pliers and crucibles, but the temperature was slightly different. A few minutes later, the process was completed, and a system prompt appeared in his mind that the gold impurities were extracted and 4 grams of gold was obtained.

4 grams of gold?

Li Mu calculated in his mind that 1 tael of gold is equal to 10 taels of silver, and 1 tael is equal to 50 grams. Convert to it, 5 grams of gold is equal to 1 tael of silver, and 4 grams of gold is 8 coins of silver! This is just a piece of gold impurity! Li Mu looked at the iron ore slag piled in the southeast corner of the house and observed it carefully. If it were all the proportion just now, this pile of iron ore slag could melt at least 500 grams of gold! That is 100 taels of silver! 100 jin of money!

"What a huge waste!" Li Mu felt heartbroken when he thought of how many iron slags were transported away. This was not the slag, it was clearly a gold mountain! He didn't melt any iron ingots. He took advantage of the fact that no one was paying attention, so he would quickly dig the gold mountain, otherwise he might be transported away again tomorrow!

Using the skill of refining metals consumes 5 stamina at a time, which means that this skill is labor-saving than smelting ore. Each time the primary skill is used, it can be ignored compared to the output.

Li Mu found a big shovel, filled the stove with iron slag, and then used the refining metal. Until his physical strength was only 5 points left, he had already obtained 54 grams of gold and a copper ingot (10 kilograms). Unlike gold, silver is born with currency attributes, and copper is regarded as a material in the system. Of course, copper can also be made into copper coins. However, this requires first learning the branch skills of forging techniques to "cast", and then purchasing "cast pattern: Kaiyuan Tongbao". Only after learning it can you mint copper coins. Molding is a branch that can only be learned at the intermediate level of forging techniques, and "cast pattern: Kaiyuan Tongbao" is a high-level pattern. Judging from the current speed of skill improvement, you don't have to think about it within three or two years.

Li Mu didn't care. He got 54 grams of gold in the afternoon, so what else was there to be inconsistency? He exchanged all 54 grams of gold in the system for silver, totaling 10 taels and 8 coins. Seeing this amount, Li Mu's pressure has been greatly reduced. What does it mean to be rich with a thunder fight on the ground? That's it! After all the iron slag is refined, 100 taels of silver will be obtained. Looking at the entire Dingxiang City, you are also one of the few rich people!

However, thinking of the system's krypton gold level, Li Mu calmed down again. One hundred taels of silver seemed to be a lot, but it was only enough at the primary skill stage. When the skills were upgraded to the intermediate level, it would cost 10 cents every time they used the skills, and the price of various formulas and patterns would be at least ten times more expensive, and one hundred taels of silver would not be enough to see them. When it reached the advanced skill stage, it would be ten times more expensive than the intermediate skill stage, and one hundred taels of silver could not even buy a few patterns.

"You still can't relax!" Li Mu put away the nouveau riche's thoughts. At this time, life was getting worse. When it was time to get off work, he turned off the fire, cleaned up briefly, and closed the door of the house. With Li Siwen's care, Li Mu was quite comfortable in the military weapon supervision, at least not like others, with a supervisor standing behind him all day long. Of course, this was because Li Mu worked three days in one morning, and after finishing the work he should do early, no one would urge him.

The military weapon supervisor also had a meal at night, but Li Mu did not go to the stove to get it. Now he is no longer worth the money for food, so there is no need to be a bit of underestimated for a few steamed buns. Li Mu received the twenty-decade salary today and went home.

As soon as he came out of the military weapon surveillance, Li Mu saw a woman leaning out at his door. Who could it be if she was not Bai Qiaoqiao? Looking at her appearance, it seemed that this was not the first time she had come out to see it. Li Mu waved at her. When Bai Qiaoqiao saw it, she slipped into the yard and disappeared. Li Mu couldn't help laughing. He was a little confused whether this girl was proactive or shy. Sometimes she was scary, but sometimes she was so shy that she was confused.

After walking a few steps, Li Mu also arrived at the door. He pushed the door open and shouted, "Mom, I'm back!"

"My son is back?" Sun came out and saw Li Mu staying by the stove for a day, baking dark face, and said with a heartache: "My son has been doing the work for a day, are you tired? Qiaoqiao has prepared food long ago and is waiting for you to come back to eat. You didn't even look at it. She has been waiting for you at the door, and she has just returned to the house..." Sun was afraid that Li Mu wouldn't know that Bai Qiaoqiao was good, so he kept nagging. Li Mu handed the twenty-minute labor money he had just received to Sun and said: "Mom, count how much this is, I'll wash my face first."

"The basin is in the yard, Qiaoqiao has made you water!" Sun counted the money and did not forget to remind him. Li Mu responded and came to the yard. He happened to run into Bai Qiaoqiao who came out with a pottery jar. The two of them looked at each other, and Bai Qiaoqiao avoided with a red face.

Li Mu reached out to stop him and said, "Madam, I heard you have been waiting for me at the door?"

"I don't..." Bai Qiaoqiao did not dare to look at Li Mu's eyes, and his head turned to the side. Li Mu flashed over and blocked in front. Bai Qiaoqiao could not hide and couldn't help but give him a glance.

Li Mu laughed and leaned into Bai Qiaoqiao's ear and whispered: "When my mother goes to bed, come to my room."

After saying that, he bypassed Bai Qiaoqiao and washed his face as if everything had happened. Bai Qiaoqiao looked at Li Mu's back in a daze, and a blush appeared on his face, as if it was dyed by the fire clouds in the sky. While counting the money, Sun looked at the couple flirting with each other, and he felt extremely relieved. He had arrived in Dingxiang City and saw that the street was empty, with only soldiers and no soldiers, and there were even a commoner. How could he live in such a place? But now, she also wanted to live a life, and she lived a life of people. As long as there was someone, she could live anywhere. Seeing the couple harmonious, Sun was content.

Dinner was still porridge and dried vegetable soup, and Li Mu was so angry that he was about to fade away. But there was no way, there was only these two things at home. Now there was not even a merchant in Dingxiang City. Even if Li Mu had money to buy it, he had no place to buy it. As a result, Li Mu yearned for Chang'an even more. Although he didn't know what Chang'an was like, as the capital of the Tang Dynasty, at least in terms of food, it should be the best in this era.

"eat……?"
