"Thank you for your kindness, if I can't do it, then I will definitely find my brother, I hope that my brother won't feel troublesome at that time. Ye Qiushuang also knew that the other party was for business, so she would talk to her so much, and it would be rude to refuse, so she still left a little hope for the other party, and when the other party saw that she had refined black essence iron from the black stone, she would not die.

"Okay, junior sister, please, junior sister, the black stone is worth a lot of money, don't be reckless when the time comes. The other party still thinks that Ye Qiushuang is a little girl who can't learn anything about refining, and spending so many black stones is just for fun, so he reminds him.

"Thank you, brother. Ye Qiushuang didn't say anything except thanks, and followed him into the boiler room.

Came to a deep cave, the heat came to her face, this should be caused by the flames of the volcano, Ye Qiushuang followed in, the internal space of the cave is very huge, almost the entire mountain is hollowed out, and the volcano is deep underground, Ye Qiushuang can't see it, she only feels that the temperature inside the mountain is higher than outside, and it is very stuffy.

"Senior sister, the environment here is very bad, if you feel that you can't breathe, don't be strong, we often faint when we first come here, and it's not good to faint for a long time. There are alarm devices in the boiler room, if you feel in danger, just knock on the copper Luo inside, and someone will come to save you. The man reminded her. This is mainly due to Ye Qiushuang's generous hand, and she will give two lower-grade spirit stones when she leads the way and passes a word, which shows that this junior sister's net worth is rich, and she doesn't know that she is the son of that family, this kind of person should be the lady of heaven in the family.

"Okay, I see. Ye Qiushuang didn't dislike the other party's verbosity, the environment here is so harsh, newcomers to this place will indeed fall into a coma after being stuffed in the cave for a long time, which shows the difficulty of the lava trial on the north side of the mountain.

Ye Qiushuang chose a boiler room, thinking that if she couldn't stand the air here, she could escape quickly.

The whole boiler room is not large, and most of the place is occupied by a one-person high boiler, and the rest is a forging table, on which the general weapons are repeatedly forged.

If a good weapon is to be formed, it must go through several processes of material selection, refining, forging, quenching, and grinding, which seems simple, but it is very difficult to make a weapon, which requires a long immersion time. Ye Qiushuang didn't think much of her own weapon was as good as her, she just felt that if the flying talisman could be made using what she had experienced in the illusion, then it would be better for her to use the fur refining weapon she had learned in the illusion than to ask an apprentice to refine the knife she had learned.

But she didn't know if the luck would still be there this time, sometimes she was a little suspicious, what she experienced was not an illusion, but a fact, but if it was a fact, how to explain that she was here? Time could not be turned back, so she didn't let herself go to these things that she didn't have, calm her mind, she wanted to refine the weapon.

Pick up the black stone, the first step is to refine the black stone, if you choose black iron, it will not be so troublesome, but Ye Qiushuang also knows that the first price of black iron is there, even if she has money, she doesn't spend it like this, and black iron is not something that can be bought with money, and the most important thing is that black iron can be refined and there will be good and bad, in fact, refining black iron from black stone does not require any level of refining, only skills, and these skills are not something that can be mastered at will.

The reason why she was able to master these skills is because of the war in the fantasy world, in the war, the quality of the weapon is a life, if you don't take good care of your weapons, then it is very likely to die, and once you die, the people around you may not be able to escape the doom, because there is one more enemy to attack, so in the barracks, these skills are also life-saving skills, and no one will hide their secrets, and because of this kind of behavior that will not hide their selfishness, she has grown rapidly in the barracks, whether it is mental, or in terms of combat skills, but unfortunately she was too pampered in the past, and was protected too well by her parents, so that there was not enough time later, even if she is desperately growing up in the military camp, she can't keep up with the pace of the war.

While thinking about it, she had successfully refined the black essence iron, and the first time she refined, her speed was not fast, mainly because she pinched the right time. But it's been refined, looking at the black essence iron glowing with cold light in his hand, the quality is not very bad, if the knife made of these black essence iron and refined iron is used at the end of the body training realm, there is no problem.

Thinking like this, Ye Qiushuang has invested in the next refinement. Her attention is highly concentrated, she doesn't even feel the heat in the air, the heat keeps rising, and the impurities in the meridians in her body are also disappearing little by little, this feeling is unprecedented and comfortable, sweat flows down her cheeks into the clothes, and she doesn't even feel that the clothes are soaked unconsciously, until all the black stones have been refined, and the quality of the refining is much better than she imagined。 The difference between black iron and iron is that black iron is not a blade, and it has not been quenched to have the cold light of the weapon, and after quenching, this cold light will be more dazzling, which is why black iron is precious.

A big bag of black stone, the fusion of black essence iron is not a fist-sized piece, not much, but there is no loss, according to the quality of her still earns. Then the materials will be fused and forged.

She didn't plan to forge at this time, she felt that she had realized something in the refining of the black stone just now, so she wanted to cultivate well, and she refining the black stone leaf too quickly would be eye-catching, and she always had to delay a little time.

Then Ye Qiushuang began to meditate, she introduced the air flow in the dantian into the meridians, but found that the meridians seemed to be much looser than before, and soon the impurities in the meridians were forced out little by little.

"It's strange, why are there so few impurities in the meridians, and it's so easy to force one out?" Ye Qiushuang repeated again.

Suddenly, the small realm in her body loosened, and she entered the fourth level of the early stage of physical training. Originally, Ye Qiushuang felt that it was over, but she found that she could still open up the meridians, so she continued, so far, only the last four of the twelve meridians in her body were left, once these four meridians were opened, then she would be able to advance to the middle stage of physical training. However, the more you go to the back meridians, the more difficult it is to open up, especially the last Rendu Second Meridian, how many cultivators have been blocked from opening these two meridians since ancient times.
