At this point, you have to use the "Alchemy Technique" left by the old man, and there are a lot of recipes in it, both advanced and low-level, and they are very detailed.

If you can understand all the techniques of this refining tool, so as to comprehend it clearly, then it will directly become a mobile treasure trove of refining weapons, and you can draw whatever you need.

Qin Nan inherited part of the memory of the elder, and there were a lot of things about the art of refining weapons. And after he obtained this book, he carefully looked at it, and when the two were combined, basically the entire book had been deeply imprinted in his mind, just waiting for Qin Nan to put it into practice.

"Grow steel, add some Kelin stone, and it will never rust. Five refined iron, add some blue stone powder, the hardness is increased by 40%, and the appearance changes from black to white, which can directly save the effort of grinding. ”

Qin Nan Yuanshen walked between the pile of materials and the five refining furnaces, his arms dancing rapidly, his mind recalling the content of the alchemy essentials, and then calculating whether it was reasonable or worthwhile.

After all, some auxiliary materials are very precious, and if they are added to the refining materials, it is likely that after the artifacts are refined, the price of the sale will not even be recovered.

However, Qin Nan won't care about these things now, because the old man has a lot of materials here, and it doesn't matter if he loses it or not. His current purpose is just to practice his hands, and he has not yet reached the point of calculating catties.

"Fifty percent green steel plus fifty percent iron phosphorus can be synthesized into corrosion-resistant steel. Seventy percent ice steel and three percent horseshoe can be synthesized into intermediate high-grade materials, but you need to add some extra limestone"

Pieces of materials were put into the refining furnace by Qin Nan, and the movements were fast, one person practiced on the five refining furnaces at the same time, and he also had to observe the movement in the furnace, take care of the fire, etc., these jobs were not so easy to do.

An ordinary refiner might have shook his head, but Qin Nan gritted his teeth and persevered. Moreover, he is not so successful in refining every time, and the average failure rate is as high as forty percent, especially for some materials, because of material problems, the possibility of refining scrap directly reaches eighty out of eight, which is equivalent to refining ten times, and eight times are failures.

After every failure, Qin Nan had to throw the scrapped materials into the furnace to refine them again, decompose the original materials that had been mixed together, and then return them to the furnace for refining.

Failed again and again, again and again, back and forth, over and over again, Qin Nan couldn't remember what his success rate and failure rate were.

And he paid little attention to it, he only knew that if he did it, he would succeed and gain some experience. And if he doesn't do it, he won't succeed and won't gain any experience, let alone success and failure.

The road of refining tools must be in accordance with the rules, and there are no shortcuts to speak of. It was precisely because Qin Nan realized this fact that even he had to start working it, strengthening himself with the knowledge he had gained and high-intensity training.

In the blink of an eye, a few days passed, and one night, Qin Nan was refining weapons in the wooden house, and suddenly the voice of the ancestor of the Xiao family came from outside.

"Elder Qi, are you there?"

When Qin Nan heard this, he suddenly perked up, calculating the time, today is indeed the tenth day, I didn't expect the time of the ancestor of the Xiao family to be so accurate, no more than ten days, no less.

Qin Nan stopped the refining work in his hand, straightened his voice, and said, "Is it the tenth day today?" Okay, the old man will go with you to the Xiao family and help you refine the red horn iron. ”

"Great, thank you for your help, so dare to ask the kid if I'm waiting here and going to the Xiao family with you, or will I go first, and you'll go alone?"

It seems that he also knows that the old man has a strange temperament, so he doesn't dare to offend lightly, no matter what it is, he has to ask the old man first.

"You go first, the old man knows where the Xiao family is, and then he will come. Qin Nan looked in the direction of the courtyard and said pretendly.

He didn't want to be with the ancestor of the Xiao family, in case he saw any flaws on the road, it would not be good, he had to be cautious. So Qin Nan let the old ancestor of the Xiao family go, and he would then go to the Xiao family.

"Okay, the kid knows, pay attention to safety on the old road and retire. The ancestor of the Xiao family said, and went away alone.

He really has great respect for the old man, even if he talks to the old man outside through the wall and the courtyard gate, he will bow his waist slightly, and then arch his hands, he doesn't dare to raise his head, looking very solemn.

After the ancestor of the Xiao family left, Qin Nan hid his physical body, and then the Yuan Shen manifested into the appearance of the old man, found a black robe similar to the old man's body and draped it on his body, and tried his best to dress himself inside and out.

At that time, as long as the other party does not release the divine mind to spy on Qin Nan's cultivation, then there should be no flaws.

After all, the ancestor of the Xiao family respected Qin Nan too much, and he didn't dare to spy on Qin Nan's cultivation at will, because it was extremely impolite to test other people's cultivation at will.

After getting ready, Qin Nan floated out of the wooden house and flew directly over the courtyard gate, before slowly heading to the Xiao family.

Qin Nan flew silently in the night sky, a few hundred meters above the ground, a large number of houses crossed under his feet, and the entire refining city could see half of it.

This is the first time that he has not used the Peacock Ming King Wing, and only used the Yuan Shen to fly in the air.

In comparison, the feeling of the two is very different.

The movement of the Peacock Ming King's Wing is very strong, and it itself will set off a very strong wind. The original god is different, the original god almost does not make any sound, and directly flutters in the air, extremely soft, and there is no difference between it and ghosts.

It's just that Qin Nan didn't fly as fast as the Flying Martial Scripture with the Yuan Shen.

At this time, everything was silent, most of the shops in the refining city had turned off their lights and closed, and there were very few pedestrians. It took a few minutes to reach the Xiao family's mansion from the old wooden house.

Qin Nan did not go through the main gate, but flew directly over the Xiao family's mansion, and then went to the octagonal tower in the Xiao family's forbidden land.

There were hundreds of guards in the Xiao family, and no one was stunned to see this black-robed figure flying over from above and going to the forbidden land of the Xiao family.

I don't know if it was arranged in advance by the ancestor of the Xiao family, Qin Nan thought so.

At this moment, the door of the Xiao family's octagonal building is open, there are no lights inside, and it is dark.

It seems that it should be, it was arranged by the ancestor of the Xiao family. He even had an impact on the Yuan Shen with the blood of a martial artist, so he removed the guards of the Xiao family, and there was not even a light in the octagonal tower. R1058
