Although Li Mu didn't know what a living house person was, he also understood that this was already Li Shimin's limit. If you are no longer satisfied, it will really be a bit embarrassing. The emperor is the most moody creature in the world. If you treat him ten thousand times, he will take it for granted, because you are his courtier, but if something doesn't go your way, life and death are just a line between life and death.

Although Li Mu has been working hard, he has struggled for some dignity and freedom for himself. But he won't waste his 'favorability' at will, and he will do it almost, and moderation is the best result. Moreover, the goal he wants to achieve has basically been achieved, which is already very good.

Accompanied by the two emperors, an old man and a young man, he had a meal, and sent away the shareholders who had eaten a meal, and Li Mu also said goodbye and left to go home. He originally wanted to find Wang Ou to say a few words, but he didn't find it, presumably Wang Ou knew that Li Shimin was there, deliberately dodged, and left early.

Li Mu was a little stunned, but he didn't take it too seriously, after all, there was still tomorrow. If the relationship between the two is long, especially in the morning and twilight. It's always tired of being together, but it doesn't have that taste.

Li Mu returned home and learned that Dugu Jiu had returned. came to him with Li Chongyi, Dugu Jiu's residence was placed next to Li Chongyi's room, and the two became neighbors. Although it is not as luxurious as Dugu Jiu when he was at home, he lacks nothing. And I also set up a warm kang, so I don't feel cold at all. When the two of them entered the house, Dugu Jiu was holding a pen and drawing something on the mask, and saw Li Mu and Li Chongyi coming. After a moment's hesitation, he opened his mouth and said hello.

If it weren't for Li Mu and Li Chongyi having heard his voice, he would never have spoken. When he first came to the mansion yesterday, when Li Mu introduced him to Bai Qiaoqiao and Li Zhien, he was also willing to speak only when he put on a mask.

Li Mu had seen a lot of two-dimensional things in his previous life, and he didn't have much feeling for Dugu Jiu's voice. It's very simple, take off the mask as a girl, put on the mask as a boy, anyway, he doesn't have any special thoughts about Dugu Jiu, isn't it the same as a younger brother or sister. As for Li Chongyi, he has not yet developed to the point where he has feelings. And in his eyes, Dugu Jiu is too much like a 'weak' woman, and he can't arouse his interest at all. That is, in the prison, when the two of them were fighting, he looked at Dugu Jiuyi a little.

Li Mu saw him drawing on the mask and said with a smile: "What, don't you think this mask looks good?" ”

Dugu Jiu shook his head, he was holding a pen in his hand to draw, like a lady of the family, and said while putting down the pen: "The mask is very good, I just think that the lack of patterns is too abrupt, so I want to draw something." Big brother, what do you think of my drawing? ”

Li Mu glanced at it and almost didn't laugh out loud. The things painted by Dugu Jiu looked like they were drawn by women. And his behavior is very strange in itself. A good big man, or a big man who dances with knives and guns, what kind of paintings do you draw?

But Dugu Jiu liked it, and he couldn't say anything, so he nodded vaguely. Dugu Jiu didn't care either, and continued to draw very seriously. This mask is his 'face' in the future, and he cares about it very much.

"Little brother, did you go home today to pick up your things?"

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

He handed the sword to Li Mu and said, "Big brother, I'm just going back to get the weapon." ”

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

Dugu Jiu was obviously very satisfied with his sword, and said, "Big brother, my father worked hard to get this sword. The provenance of this sword cannot be examined, but it seems that it should be a Han sword. It's especially sharp, and I like it a lot. ”

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

[Qingfeng Sword: One-handed sword. The Qing Feng sword of the Han Dynasty, the sword embryo is mixed with meteoric iron, which is extremely sharp. 】．

[Base Strength Requirement 15].

[Dexterity +3].

[Stamina +3].

【？ 】．

Question mark?

Li Mu frowned slightly, the question mark was the first time he had met it. Presumably it has something to do with the meteorite in the sword embryo, meteorite iron, which sounds like a high-grade material. If the inference is correct, it should be the swordsmith who forged this sword, and regarded the meteorite as ordinary iron, resulting in the fact that the proper characteristics of the meteorite iron were not fully brought into play.

Li Mu weighed the sword and said, "Little brother, your eldest brother and I are actually a weapon master. The big man's axe was made by me. I think your sword is a little bit off the fire, if you can trust me, I can try it and make it better. ”

Dugu Jiu didn't hesitate, nodded and said, "I believe in the eldest brother, and the eldest brother will dispose of it at will." ”

"Good!" Li Mu put the sword back into the scabbard and said, "Just do what you say, you can also help." Big man, go, let's make a stove! ”

Li Chongyi answered, and the three of them came out of Dugu Jiu's residence and came to Li Mu's studio. Dugu Jiu came for the first time, saw all kinds of tools in the studio, and knew that what Li Mu said was true, and he had real skills.

Li Mu asked him to wait next to him, and raised the stove with Li Chongyi. Li Chongyi and Li Mu have worked together many times, and they have long been familiar with these jobs. In a few moments, the fire was red.

Li Mu put Dugu Jiu's sword into the furnace, gritted his teeth, and bought a [Forging Catalyst] from the system store. This [Forging Catalyst] alone cost him a thousand yuan!

The effect of the forging catalyst increases the temperature of the furnace for a certain period of time. Its effect is affected by the user's forging level and furnace level.

Ancient smelting techniques, the highest level of craftsmanship, can create temperature conditions, the maximum 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, so it can only retreat to the next best thing, after repeated forging at a certain temperature, squeeze out the debris and bubbles, and improve the mechanical properties of iron through the method of 'carburizing'. During the Han Dynasty, craftsmen invented the technology of '100 steelmaking', which increased the number of repeated heating and forging, which not only processed and formed, but also reduced inclusions, refined and homogenized, and greatly improved the quality of steel.

Since the Han Dynasty, the skills have gradually stabilized, and there has been little change. Whether it is 'a hundred refining' or a 'thousand refining', after all, it is repeatedly forged, and if it cannot reach the melting point, it cannot completely solve the problem of debris and tiny bubbles. At this time, the right meteorite iron highlights its value.

Meteorites come from space, and some of them are pure iron in their own right. After the friction of the atmosphere, it reaches a high temperature of thousands of degrees, far exceeding the melting point of iron. The process of falling is not an exaggeration to call it 'molten iron', and it is used to forge weapons, and the material must be superior.

[Forging catalyst] can make the temperature in the furnace exceed 1500 degrees Celsius in a short period of time, reaching or even exceeding the melting point of iron. In this way, the forged weapon will have fewer impurities, fewer tiny bubbles, and more uniform carburizing.

[Forging Catalyst], thrown into the furnace, the originally yellowed flame instantly erupted into a burst of blazing. As if the sun was setting in a furnace, Li Mu knew that the [Forging Catalyst] would not last long, and he raced against time to see that the iron sword was burning red, and there were faint signs of melting, so he took it out and put it on the anvil, picked up the hammer and smashed it.

He didn't dare to use Li Chongyi to do it for him, because this was upgrading weapons, not forging weapons. Li Chongyi only has brute force, he is a 'hydraulic press', he only knows how to smash, he can't control the strength, and he doesn't know the heat and skill. And the sword embryo is not the same as his giant axe, with such a thin sword body, Li Chongyi hammers down, and the only consequence is to break it in two, which is not good at all.

Li Mu activated his skill, and the tapping sound was one after another, and the sound was faster, and an afterimage was picked out from his right arm. He repeated this many times, and only then did he stop, knowing that the fire had turned back into a yellowing flame.

The blade of the sword was placed in the quenched stone trough, and the room was suddenly filled with steam. When the water vapor dissipated, Li Mu took out the sword from the stone trough again, and the sword body was already a circle smaller than before, but the sharpness was far greater than before. The blade of the sword is shining blue and imposing.

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

[Meteoric Iron Sword (nameable): One-handed sword. Meteorite is beaten and refined for a long time; There is no blood in cutting people, and iron is like clay. 】．

[Basic strength requirements 12].

[Dexterity +5].

[Stamina +5].

[Sharpen iron like clay].

Li Mu gasped, he didn't expect to upgrade a golden equipment with special attributes. By default, forging weapons without attributes is white, with one attribute is green, with two attributes is blue, with three attributes is gold. Normally, the third attribute is also a stat point bonus, such as strength. However, this weapon, with the trait of 'sharpening iron like clay', means that it is even more superb, because it can damage blades below the same level.

In addition, after the upgrade, the base strength requirement has been reduced by 3 points. In other words, if you are in the game, you can use this superb weapon when the character level is lower, and if you hold it with a trumpet, you can also damage other people's weapons, which is not too cool!

But now it's not in the game, Li Mu is a little curious, whether this 'sharpening iron like clay' can really 'sharpen iron like clay'. Li Mu carried the sword, came to the place where the iron ingot was placed, made two strokes, and slashed down!

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

Is this still your own sword?!
