Three days passed quickly, in these three days, Lu Fan had no chance to make a flying machine again, what is needed to engrave the rune is a strong control, if he can't control the surge of strength, not to mention that the inscription has not been successful in the first place, even if it is a fire-type gun, he may make a mistake.

But after three days of familiarization, Lu Fan has also been able to control his strength very well, but to be meticulous, this is not something that can be done in a day or two.

In the early morning, the morning sun sprinkled in the courtyard and woke up everything, but Lu Fan had already woken up, standing in front of the workbench, and picked up the rune carving knife.

Lu Fan still wanted to try one last time, after all, if there was a flying machine, the probability of success in his later plans would be many times higher.

Lu Fan is not a fool, he knows that if he sells those things at auction, others will definitely be able to associate his identity, and the Federation Rune Master and Apothecary cannot copy it, which is an advantage, but it is also a disadvantage.

But he knew that his identity might be exposed, so he still decided to sell these things, except for helping the little fat man, he didn't have the slightest desire for Bai Zhi to know what he meant here.

If Bai Zhi was still alive, she knew that she was here, and she would definitely rush over.

And this auction was held in Noh Star, because of the front-line war, the palace-level masters were either transferred to the front line or stationed in the Federation to prevent those aliens from raiding the Earth base camp.

This is also the reason why Lu Fan dares to reveal his identity, he is betting, he bets that Bai Zhi can understand what he means, and he also bets again, whether there will be a palace-level master in this auction.

Therefore, the flying machine is very important, this is his biggest reliance on escape, even if his strength has skyrocketed now, he is confident that he is not afraid of any professional-level cultivation, but what if it is a dozen?

In the past three days, in addition to training his control of energy, Lu Fan has also been thinking about the matter of the flying machine rune, and at the same time, it has also made him really calm down, which is a good thing for him.

Although the auction was held today, it was not in the morning, but in the evening, so Lu Fan still had a lot of time to squander.

Holding his breath and concentrating, thinking back to the runes and all the details, just like every time he had engraved the runes before, when everything was ready, Lu Fan began to drop the first stroke, and then did not stop, carefully and smoothly wielding the rune carving knife.

One minute, two minutes......

An hour, two hours......

Finally, Lu Fan was once again engraved to the place where there had been countless failures before, and at this moment, Lu Fan's spirit hit like never before, and fine beads of sweat began to appear on his forehead, and even the beads of sweat flowed to his nose, forming a transparent drop of sweat, and he couldn't care about it.

At this moment, a gust of wind blew, blowing the beads of sweat on the tip of his nose onto the workbench on the side, and he simply didn't fall on the rune that Lu Fan was inscribed.

However, looking at the falling beads of sweat, Lu Fan fell into deep thought, and the runes that lost Lu Fan's control naturally quickly shattered, but Lu Fan stayed in place, and his mind was full of pictures of the drops of sweat dripping.

Yes, it's the wind, just like the wind can blow off sweat droplets, and the wind can take me flying, but how can I control the wind?

After all, I didn't want to be smashed on the workbench like that bead of sweat.

Lu Fan's mind began to spin, and suddenly, the scene of the battle with Chen Ao appeared in his mind, and when he fought against Chen Ao, Chen Ao was flying in the air most of the time.

How did he do it?

At such a critical juncture in the battle, Lu Fan naturally didn't have time to think about these issues, but now, Lu Fan had enough time.

Just like a videotape, Lu Fan's mind has always been filled with images of Chen Ao flying, even the images of Chen Ao fighting them outside the Flame Swamp before, and the images of Chen Ao falling to the ground due to the impact sound.

Over and over again, these pictures were replayed over and over again, and slowly, Lu Fan no longer looked like he was playing back, but as if he had become a spectator of these two battles, he could see every little movement of himself, even the fluttering of his clothes that he didn't know.

He could also feel the changes in the energy around Chen Ao's body, even if he had never had this image in his memory.

I don't know how long it has been, Lu Fan is like a quiet bystander, looking at these pictures over and over again.

Suddenly, a smile appeared on the corner of Lu Fan's mouth.

"Yes, it's the wind ......"

Lu Fan sighed lightly, and his eyes gradually returned to clarity, and at this time, it was already the middle of the day, and he was in a daze for a long time, at least, in the eyes of Xiaoying, who was waiting next to him for a long time with food, he was in a daze.

Lu Fan, who was in a good mood, smiled at Xiaoying, and after eating some food casually, he took out a rune module again, and this time he directly engraved the rune without even resting, because he was already in his heyday, and he had never felt so good as he did now.

Xiaoying on the side looked at Lu Fan, who was in a frenzy, with some confusion, but she still obediently walked out of the laboratory with food, and closed the laboratory very intimately, standing at the door, like a guardian saint, staring at everything in the outside world.

Many things are like this, if you don't understand, even if you spend thousands of years and hundreds of years, it is impossible to make the slightest progress, but if you understand, maybe you can do it in the next second.

Just like Lu Fan at this time, three hours later, looking at the vest in his hand, Lu Fan was very satisfied, the reason why he made it look like a vest was to facilitate manipulation, and he didn't have to take it out every time he used it.

What he lacks is only an understanding of the wind, and it is not up to you to write down the runes, if so, then the job of the rune master is too simple.

The so-called aircraft of the Federation are actually somewhat similar to a set of simple armor, and there are many parts at each joint, because these aircraft use airflow, in order to meet the requirements of repair, jet modules must be installed at these joints, otherwise it will not only be inflexible, but will make the repair lose balance.

It can be said that it is very inconvenient to wear, but even such a flying machine is hard to find.

And Lu Fan's flying machine will not have this shortcoming, because, with Lu Fan's flying machine, what takes him to fly is not an air current, but a wind.

The value of such a flying machine is beyond doubt.

Looking at the sky, Lu Fan took out a piece of material again, and continued to start carving, imagining what kind of sensation such a flying machine would cause if it appeared in the auction hall, Lu Fan still had some expectations.

What's more, he still has a treasure like Nirvana Fruit, when these things appear, Lu Fan believes that it should not be a problem for the little fat man to win this competition.
