At midnight, the moon was high in the sky.
Yun Su stood in the courtyard and looked at the bright moon. After a short seclusion today, he had already deduced some key points of the flying technique.
During the day, when he saw the City God hiding things with a divine technique and riding a divine wind of incense, he had an idea. He wanted to deduce a flying technique and a method to hide things.
Considering that deducing spells was extremely exhausting, after weighing the pros and cons, he chose to prioritize deducing flying spells.
If it was just a question of whether he could fly, it would naturally be much simpler. However, the flying technique that Yun Su wanted to deduce was more demanding.
The first thing was to be safe.
As a Soul Formation cultivator, he was extremely confident that he would not die even if he fell from the sky.
However, flying was not only used for traveling. In a battle between cultivators, they could encounter each other in the sky, the ground, the water, and the fire. If they fought in the air and their flying technique was not perfected, there might be problems.
The second thing was to be fast enough.
He was immortal and had once traveled the Great Void. Yun Su no longer yearned for ordinary flying techniques. He was like the legendary monkey in the Journey to the West. His standards had become a little high, so he naturally hoped to fly safely and quickly.
Killing the enemy was not considered strong. When he could defeat them, he would leave afterwards, leaving behind a group of people who could only eat dust hatefully.
If he can't win, then run. True strength comes from not being able to be caught up on.
The last thing was convenience.
The Art of Flying had always been an auxiliary technique. Without considering escaping, if flying required a lot of concentration and magic power, the gains would not make up for the losses.
"As an immortal cultivator, I still need to have some immortal aura to be able to hold on."
The more Yun Su thought about it, the better he felt. He was vaguely excited and looked forward to flying even more.
The last time he went into seclusion was to digest his insights from traveling the Great Void. Although it was only a drop in the ocean, it still allowed his cultivation to improve greatly. Although his cultivation level was still at the Soul Formation realm, he had glimpsed some of the rules of the world. After some time, when he perfected it and was sufficiently prepared, he could find a place where spiritual energy gathered and try to break through.
These laws of heaven and earth and comprehension of the Great Dao might not be enough to overturn the mountains and rivers but it was very useful to deduce some things or have some understanding of them.
This was how the Yin-Yang Fish Diagram and the Five Elements Technique were deduced.
This time, Yun Su had prepared five ideas for the flying method.
The first was to fly on a weapon.
To fly on a weapon, one first needed to engrave a flying array formation or the power of the wind on it. Then, one had to spend a large amount of time refining the weapon to be smooth. Usually, when cultivating, one had to spend some time on it. Even if one could not communicate telepathically, one had to control it naturally. Then, when they used it, they could use it to fly.
That was also the most common way for cultivators to fly.
If the flying array engraved on it was too crude, or if one's comprehension of the power of the five elements was insufficient, or the refinement of the weapon was not smooth enough, it was very easy for flying to fail.
Therefore, flying was a very difficult thing for ordinary cultivators. It would be fine if it was an immortal sect with an orderly inheritance. They did not lack artifacts and elders. As for ordinary itinerant cultivators and foreign species, it was not easy to cultivate their bodies to be as light as a swallow and fly at high speed in the air. It was not as fast as jumping and flying low on the ground.
In the library of the Wang family's mansion, Yun Su saw many miscellaneous books and novels about immortals and monsters, such as "Nanko Immortal Fate" and "Sword Immortal in the Clouds". Be it words or pictures, most of them were about flying on swords. The rest were mostly about various weapons. They were used for self-defense, attack, and flight. It could be said that there were hundreds of styles.
Ordinary flying was usually in the low sky. It was enough to fly above the peak of the mountain. If one flew too high, it was easy to fall to their death. There was a story in a miscellaneous book about a woodcutter meeting an immortal. The so-called 'immortal' was someone who fell from the sky and almost died.
On that point, Yun Su had absolute confidence in the Heaven Slaying Sword. It could be used easily. There was no need to inscribe array formations and refine them. Moreover, it was fine to fly low in the sky. He just did not know if the Astral Layer, which was extremely dangerous to cultivators, could be flown in.
The second was the Beast Taming Method.
If they could find a flying spirit bird or animal, whether it was a spirit bird demon or some other spirit beast, once it was tamed, they could ride it out. The common ones were mostly birds, such as cranes, eagles, and birds of prey. As long as they were not wild beasts, they would be good mounts.
In the eyes of mortals, those who could control beasts and fly were all high and mighty immortals. This meant that they were powerful. The stronger the mount, the faster they could fly without consuming any magic power. At critical moments, they could even help fight. After a long time, they could even transform into human form and serve their master.
However, Yun Su had nowhere to capture one for the time being. He might not be interested in a random demon, so he gave up for the time being.
The third was the Art of Air Manipulation.
This kind of Air Manipulation Technique was the most mysterious. One could come and go without a trace, hiding between the five elements of heaven and earth. With Yun Su's cultivation in the Soul Formation realm, he could fly with a thought. It was extremely mysterious but it consumed too much magic power. It was not suitable for ordinary cultivators to fly, nor was it suitable for long-distance flying.
The fourth was the Rules Method.
The Rules Method was based on the understanding of the five elements and the affinity with the world. One also had to be able to touch a trace of the rules of space in the world. To teleport over a long distance, one had to break a certain shackle.
Yun Su also tried and realized that it was not impossible to forcefully open this shackle with just his Soul Formation cultivation. It was a pity that the preparation time was too long, the speed was too slow, and the fact that it did not give him the agility he wanted. The consumption was too great and it was very unsafe.
This method could be used to escape as a last resort but it was not suitable for daily life.
Yun Su liked the fifth method the best and had thought of it the earliest.
That legendary monkey did not learn a lot of things but shamelessly learned the Somersault Cloud. Later, with this divine power, he killed and plundered. He was successful in his travels.
There was no place to learn the Somersault Cloud but it could be deduced.
"Gather!"
Yun Su formed a hand seal and reached out to summon a cloud that floated across the night sky. The huge cloud was guided by magic power and kept shrinking. When it finally landed, it was only three square feet in area.
The clouds seemed to have solidified. It was different from what he had imagined. Instead, it was filled with water vapor. With a flick of his finger, he shot it towards the empty space in the courtyard, and it started to drizzle.
"Invoke!"
Yun Su did not give up. Although the rain cloud that he had just thrown away was mostly made out of water vapor, there was a cloud Qi inside. He cast another spell and summoned a small cloud that was about a square foot in area.
This time, it only gathered slightly. He reached out and touched it lightly. It still had a texture and was a little softer than cotton candy.
He flew up lightly and stepped on it. It was as if he was standing on water, floating slightly. He actually managed to support himself and did not fall.
"Rise."
With a thought, the clouds slowly rose and carried Yun Su high into the sky. He crossed the courtyard wall and slowly flew into the air.
When moving front, back, left, right, up, and down, his magic power triggered the power of the wind between heaven and earth. It was very easy to fly and the consumption was not big.
