Although Li Mu didn't know what a living sacrificial servant was, he also understood that this was Li Shimin's limit. If he was not satisfied, he would be a little embarrassed. To accompany the king is like a tiger, and the emperor is the most unpredictable creature in the world. He would think it would be natural for you to treat him ten thousand good things, because you are his subject, but if something goes wrong, life and death are just between the front lines.

Although Li Mu has been working hard to struggle for some dignity and freedom for himself, he will not waste his "favoriteness" at will. He has done almost the same thing, and the best result is to stop at the right time. Moreover, the goals he wants to achieve have basically been achieved, which is already very good.

With the two emperors, one old and one young, they gave away all the shareholders who had eaten for a meal. Li Mu also said goodbye and left home. He originally wanted to say a few words to Wang Ou, but he didn't find it. It must be that Wang Ou knew that Li Shimin was there, so he deliberately avoided and left early.

Li Mu felt a little sad, but he didn't take it too seriously. After all, there is still tomorrow. If the relationship lasts for a long time, especially in the evening, I will always get tired of being together, but the taste will be gone.

When Li Mu returned home, he learned that Dugu Jiu had returned. He came to find him with Li Chongyi. Dugu Jiu's residence was placed next to Li Chongyi's room, and the two became neighbors. Although it was not as luxurious as Dugu Jiu was at home, he had nothing to lack. And he also built a warm kang, so he would not feel cold at all. When the two entered the room, Dugu Jiu was drawing something on his mask with a pen. When he saw Li Mu and Li Chongyi coming, he hesitated for a moment and greeted him.

If Li Mu and Li Chongyi had not heard his voice, he would never have spoken. Even when he first came to the mansion yesterday and Li Mu introduced him to Bai Qiaoqiao and Li Zhien, he would have worn a mask before he could speak.

Li Mu saw many things in the second dimension in his previous life, and he didn't feel much about Dugu Jiu's voice. It's very simple. Take off his mask and treat it as a girl and wear it as a boy. Anyway, he doesn't have any special thoughts about Dugu Jiu, so it's not the same as treating it as a younger brother or younger sister. As for Li Chongyi, he has not yet developed to the point of feeling it. Moreover, in his eyes, Dugu Jiu is like a "weak" woman and can't arouse his interest at all. In other words, when the two of them were fighting against each other in prison, he looked at Dugu Jiu slightly in the first time.

When Li Mu saw him drawing on the mask, he smiled and said, "Why, do you think this mask is not good-looking?"

Dugu Jiu shook his head. He looked like a lady with a pen in his hand. He said while writing: "The mask is very good. I just think it's too abrupt without a pattern, so I think I'm going to draw something. Brother, how do you think I'm drawing?"

Li Mu took a look and almost laughed out loud. The things Dugu Jiu painted were drawn by a woman at first glance. Moreover, his behavior was very strange. A very good man, a big man who was dancing with a sword and a gun, would he draw?

But Dugu Jiu liked it, and he didn't want to say anything, so he nodded vaguely. Dugu Jiu didn't care and continued to paint it very seriously. This mask is his future "face", which he cared very much.

"Brother, have you been home today to get the things back?"

"Yeah." Dugu Jiu nodded, put the mask aside, opened the cabinet and took out a sword.

He handed the sword to Li Mu and said, "Brother, I'm going back to get the weapons."

Li Chongyi glanced at him, curled his mouth, lowered his head to stroke his axe. Not to mention whether Dugu Jiu's sword is good, he doesn't like the weapon "sword" alone. It's too light and is not suitable for chopping and slashing, and it is not practical enough in actual combat. Compared with his giant axe, it is not worth mentioning at all.

Dugu Jiu was obviously very satisfied with his sword and said, "Brother, my father took a lot of effort to get this sword. The origin of this sword is unspeakable, but it seems that it should be a Han sword. It is particularly sharp and I like it very much."

Li Mu pulled out the sword, thoughts moved, activated the system, and the situation of the sword appeared in his mind.

[Qingfeng Sword: One-handed sword. Qingfeng Sword of the Han Dynasty, the sword embryo is mixed with meteorite, extremely sharp.].

question mark?

Li Mu frowned slightly, and it was the first time he had met the question mark. It must be related to the meteorite in the sword embryo. Meteorite sounds like high-level materials. If the inference is not bad, it should be the sword-caster who casts this sword, treating meteorite as ordinary iron, which has not fully demonstrated the characteristics of meteorite.

Li Mu weighed the sword and said, "My brother, my elder brother, I am actually a weapon master. The big axe was made by me by myself. I think your sword is still not too late. If you can trust me, I can try it and make it better."

Dugu Jiu nodded without any hesitation, "I believe in my elder brother, I will just deal with it at will."

"Okay!" Li Mu took the sword back into the scabbard and said, "Do it just by saying that, come and help. Big guy, go and make the stove!"

Li Chongyi responded, and the three of them came out of Dugu Jiu's residence and came to Li Mu's studio. It was Dugu Jiu's first time to come. Seeing all kinds of tools in the studio, he knew that what Li Mu said was not false, but that he had real skills.

Li Mu asked him to wait by the side and lifted the stove with Li Chongyi. Li Chongyi and Li Mu made iron many times and had already become familiar with these tasks. After a while, the fire turned red.

Li Mu put Dugu Jiu's sword into the furnace, gritted his teeth, and bought a [forged catalyst] from the system store. This portion of [forged catalyst] alone cost him a thousand guan!

The effect of [Forging Catalyst] increases the temperature of the furnace within a certain period of time. The effect is affected by the user's forging level and furnace level.

The ancient smelting technology, the highest craftsmanship level, can create temperature conditions that will not exceed 1200 degrees. The melting point of iron is 1535 degrees, which is far from the point of melting iron into iron juice. It can only be second-hand. After repeated forging at a certain temperature, debris and bubbles are squeezed out, and the mechanical properties of iron are improved through the method of "carburizing". In the Han Dynasty, craftsmen invented the technology of "hundred steel making" and increased the number of repeated heating and forging. This not only processes and molds, but also reduces inclusions, refines and uniformizes them, greatly improving the quality of steel.

Since the Han Dynasty, the skills have gradually stabilized and there has been no change in general. Whether it is "hundred refining" or "thousand refining", it is repeated forging. If the melting point cannot be reached, the problems of debris and tiny bubbles cannot be completely solved. At this time, the appropriate meteorite highlights its value.

Meteorite iron comes from space, and part of it is a pure iron block. It also reaches a high temperature of tens of thousands of degrees after the friction of the atmosphere, which far exceeds the melting point of the iron. It is not an exaggeration to call it "melted iron" in the process of falling. It is used to forge weapons and be superior in materials.

[Forging Catalyst] can make the temperature in the furnace exceed 1500 degrees in a short time, reach or even exceed the melting point of iron. In this way, the forged weapons will have fewer impurities, fewer tiny bubbles, and more even carburizing.

[Forging Catalyst], when put into the furnace, the originally yellow flame burst out with a burst of light. As if the sun was setting in the furnace, Li Mu knew that the [Forging Catalyst] would not last long, and he raced against time. Seeing that the iron sword was burning red, there were signs of melting, he took it out and placed it on the anvil, and swung the hammer and smashed it.

He dared not use Li Chongyi to do it for him because it was an upgrade weapon, not a forging weapon. Li Chongyi only had brute force, he was a "hydraulic press". He only knew how to smash, could not control the strength, nor did he know the temperature and skill. Moreover, the sword embryo was different from his giant axe. With such a thin sword body, Li Chongyi only had one consequence that it was to break into two pieces, which was not possible at all.

Li Mu activated his skills, and then knocked, and quickly passed, and a afterimage swung out of his right arm. He stopped after repeated this and knew that the fire had turned back into a yellowed flame.

Putting the sword body into the quenched stone trough, the water vapor suddenly lingered in the studio. When the water vapor dissipated, Li Mu took out the sword from the stone trough again. The sword body had shrunk a circle compared to the original one, but its sharpness was far better than before. The sword blade shone with green light and its momentum was striking.

Looking at the properties of this sword at this time, it has changed.

[Meteorite Iron Sword (nameable): a one-handed sword. Meteorite Iron is beaten and refined for a long time; killing people without blood, cutting iron like mud.].

[Sharpening iron like mud].

Li Mu took a deep breath and unexpectedly upgraded a golden equipment with special attributes. The system defaults to forging weapons, without attributes, with white characters, with one attribute, with green characters, with two attributes, with blue characters, and with three attributes, with gold characters. Under normal circumstances, the third attribute is also a bonus of attribute points, such as power. However, this weapon has the characteristic of "sharpening iron like mud", which means it is even more excellent because it can damage weapons below the same level.

Moreover, after upgrading, the basic strength requirements are reduced by 3 points. In other words, if you can use this top-quality weapon when the character level is lower in the game, if a small account holds it, it will be almost invincible at the same level. When PVP, it can also damage other people's weapons, which is simply too cool!

But now it's not in the game. Li Mu is a little curious whether this "cutting iron like mud" can really "cut iron like mud". Li Mu carried the sword and came to the place where the iron ingot was placed, gestured twice, and slashed it violently!

Dugu Jiu didn't expect Li Mu to do this. It was too late to stop him. He grinned subconsciously in pain. Suddenly he widened his eyes because he saw an incredible scene. The three-inch thick iron ingot, and with one sword, it was divided into two, and the blade was not damaged at all!

Is this still my own sword?!
