In fact, now Feng Shitian's heart is very unhappy and awkward!

The reason is that this is really a bit too simple to make parallel goods keys, all she needs is to knock a few times casually, but now the old guy from Yun Tianbury is sitting on the side staring intently at the movements in his hands, so now Feng Shitian is really a little embarrassed!

What the hell is she going to do to make this counterfeiting process like a real key?

Feng Shitian's brows furrowed slightly, and then she took out a piece of metal that had been burned red from the refining instrument ding, and then struck the cutting board in front of her, and sparks flew everywhere with every hammer!

One, two, three......

I kept knocking this piece of metal until it was cold, and then I threw it back into the refining tripod again, and then I changed it to another piece of metal and continued to beat it!

The temperature inside the refining tool is getting higher and higher, and the flames are also raging, almost as if they are about to erupt out!

Rao is the cultivation of Yuntian burial now feels a little too hot to stand it, and he raises his sleeves from time to time to wipe the sweat from his forehead!

And at this time, he could also see clearly, Feng Shitian's face was also covered with sweat at this moment, and her hands didn't have time to raise them to wipe a handful of sweat now!

Yun Tianfu could see very clearly that a few drops of sweat slipped down from Feng Shitian's forehead and fell directly into her eyes, but even so, Feng Shitian's eyes did not close, and her gaze fell on the piece of metal!

Yun Tianfu looked at the original key in his hand, and then let out a long sigh in his heart, he can see it now, this key is really difficult to build, it is said that he has also seen the Feng Shitian Refinery, but it is the first time to see her sweating profusely and looking focused!

The impurities in the pieces of metal have been completely eliminated under Feng Shitian's knocking, and then Feng Shitian kneaded these metals together while hammering and calcining!

"This, this, this ......" Yun Tianhua Fu looked at the movements in Feng Shitian's hands in surprise, although he is not a refiner, but he has never eaten pork and has always seen pigs go, he has still heard that it is extremely difficult to knead metal like this, especially now that Feng Shitian has cleaned up all the impurities in the metal, then this will make it more difficult to knead the metal, but in the same situation, if Feng Shitian can still successfully complete the kneading, then the performance of the new metal obtained will be extremely strong and excellent!

Seeing that Feng Shitian's face, which was originally relatively white, became red under the reflection of the flames, Yun Tianyu touched his face and was also a little hot, presumably his face was now fighting with Feng Shitian!

Yun Tianfu really didn't expect that he would wait for three full days like this, and in these three days, Feng Shitian had just finished kneading all the metal!

Seeing Feng Shitian once again put the metal that had been kneaded into the refining tripod again, Yun Tianfu finally found a chance to speak: "Kang Qiu, that, that, I just remembered that there are still many things in the clan that I need to deal with, I will put this key here, I, I have to leave first!" ”

"Ugh!" Feng Shitian looked at Yun Tianfu with some strange eyes: "Master Yun, aren't you afraid that I will break that key?" ”

"Huh!"
