The old man in Xuanyi didn't say much, and directly used the dark gold pen to quickly depict it on the paper, and the few people below were staring at it without blinking, for fear of missing a little detail.

Soon, the Fengxing formation was depicted, and the old man in Xuanyi demonstrated how to fold it into a paper crane, and then calmly glanced at Feng Ruo and the others, and then took out a pile of light blue paper and distributed it to everyone.

"This is ten pieces of green crane paper, you can practice on your own, if you can depict it successfully, and you can inlay the five elements stone, the best quality, the old man will reward a popular mount!"

After saying this, the old man in Xuanyi waved his long sleeves, and then sat on his green jade immortal crane and floated away!

"Ha! Fengxing Mount! It's all me!" At this time, a ten-year-old disciple of the Heavenly Machine Academy laughed proudly, obviously he was very confident in himself.

"Hey, Senior Brother Xu is a formation genius of this Academy, there must be no problem, but I don't know what that popular mount is? If it is a green jade immortal crane, Senior Brother Xu, you will make a lot of money!" Another disciple of the Heavenly Machine Academy said with some flattery.

"Hmph! I want to be beautiful, the green jade immortal crane is the best popular mount, and the master uncle has only made such one, how can he reward us? But even if it is not the green jade immortal crane, it should not be too far behind!" Senior Brother Xu thought a little smugly.

Listening to the conversation of these people, Feng Ruo just silently put away the ten pieces of green crane paper that belonged to him, for the Fengxing mount that the old man in Xuanyi said, he did understand that this kind of mount was completely made of the Fengxing Formation, the flight speed was extremely fast, and it would not be tired, as long as there were enough Five Elements Stone to consume, it could fly non-stop, so if the cultivators in the Immortal Cultivation Realm were on a long journey, if they had the conditions, they would use this Fengxing mount.

However, the only drawback of this popular mount is that it cannot fight, so generally in dangerous areas, cultivators still prefer to use flying spirit beasts as mounts.

At this time, Senior Brother Xu and the others saw Feng Ruo put away the ten pieces of green crane paper, and they all showed mocking expressions, although they were afraid of the strength that Feng Ruo had shown before, but they had an absolute advantage in terms of formation.

"Hey, who is that, seal if yes, right? The cost of Qinghe paper is not low, you don't want to waste it, I bought it with five Five Elements Stone, if you want to talk about the formation, then you need to talk about talent, you haven't even learned the Rushan formation, how can you depict the Fengxing formation?"

Senior Brother Xu said very authoritatively, and the rest of the people also nodded again and again, looking very reasonable.

"Oh, is it?" Feng Ruo glanced at a few of them lightly, if he hadn't written down the Fengxing Formation, maybe he would really sell these ten pieces of Qinghe paper to them, but now, it's another matter!

"I'm sorry to disappoint you, but I actually want to get a Fengxing mount to play with!" Feng Ruo smiled politely at Senior Brother Xu, turned around and walked away.

"You-" Senior Brother Xu pointed to Feng Ruo's back, but he was so angry that he didn't say anything for a long time.

Feng Ruo didn't pay attention to this little episode at all, all he was thinking about now was how to portray the successful Fengxing formation, not to get the Fengxing mount that rewarded, but to be really interested.

It's a pity that Feng Ruo doesn't have the tools to portray now, even if he goes to the Tiandang Mountain Market now, it's useless.

"Otherwise, try to portray your mind yourself?" Feng Ruo suddenly had this thought in his heart.

After thinking about it, he decided not to go to the East Peak today, but returned to his newly owned courtyard, and after opening the protective formation, he entered the quiet room to start carving.

For the portrayal of this mind, even the old man in Xuanyi said that it was extremely difficult, and Feng Ruo was not sure in his heart, but fortunately he just thought it was interesting, so it didn't matter if he tried it or not.

After revisiting the steps of the depiction of the popular formation, Feng Ruo had no distractions, released his mana little by little, and then carved it onto the green crane paper, this process was like an invisible pen depicting on the green crane paper.

But this mana is not as good as the real pen, because the purity is different, the amount released is different, so every moment this invisible pen is changing, if the traces left can be seen, you can see the thickness and thinness, crooked and twisted strange look!

If it's just a simple line, or there is no big problem, but the popular formation is very complicated, so Feng Ruo only depicted it for a short while, and the green crane paper turned into ashes with a "whew".

"It's really difficult!" Feng Ruo shook his head and sighed, but he didn't stop at all, still controlling his mana and carving, and soon, the second piece of green crane paper also turned into ashes.

"It doesn't seem to work like this, the amount of Qinghe paper is not enough!" Feng Ruo thought about it, and found more than a dozen broken animal skins from the storage belt, which were all the results of his previous hunting of first-level spirit beasts, because there were too many wounds, resulting in scattered animal skins, but now it can just be used to depict the popular formation, anyway, this formation only needs to have a carrier, as for the success or not, he doesn't expect it at all, just to improve his proficiency.

These broken animal skins are really tougher than the green crane paper, each piece can make Feng Ruo carved four or five times, and finally turned into ashes, and after he consumed these dozen animal skins, his mana has also completely bottomed out, but it is not without gains, he has now been able to successfully carve half of the popular formation, thinking that if there is a special carving tool, he has already completed it.

After running the second layer of Qingyun Jue's mental formula, Feng Ruo recovered most of the mana in his body after meditating cross-legged for a few hours, but he didn't care about resting, and directly carved it on the remaining eight pieces of Qinghe paper!

Finally, on the last piece of green crane paper, Feng Ruo successfully carved a popular formation with his heart!

Without hesitation, he folded this green crane paper into a paper crane according to the technique of the old man in Xuanyi, but this was only half the success, and the last step was to inlay the Five Elements Stone!

The so-called inlay is not the kind of rough and hard putting the two together, but it requires the use of mana to transfer the power in the Five Elements Stone to the paper crane, just like when Feng Ruo refined the flame power in the Fire Surname Five Elements Stone to the long knife.

This link requires the implementer to have enough mana, not only to activate the Five Elements Stone on the one hand, but also to set aside a part of the mana to protect the paper crane from damage, which is much more difficult than refining weapons!

But the more this happened, the more Feng Ruo felt challenged! After a short rest, he began to mosaic the Five Elements Stone!
