"I see!" Su Yu suddenly said, no wonder although he had heard a lot about Edgeworth and Flying, he had never seen it.

The general sword is simply not enough to withstand the strong spiritual power output, and a good sword is just able to withstand a few more times, a good sword is not easy to get, if the sword is abolished after a few times, presumably ordinary people will not and ordinary swords are only a hundred miles away, so it is rare to see people who fly with the sword.

"But your Traceless Sword is different!" Elder Gongsun smiled deeply, if this sword was the same as an ordinary sword, Elder Gongsun would not have taught a sword-like sword.

"Master, please!" Su Yu's eyes lit up, and he immediately handed the Traceless Sword to Elder Gongsun.

"It is true that an ordinary sword can only be destroyed a few times, but this sword will not be like this, the strong spiritual power of the sword art will not only not make it collapse, but can nourish this sword, in the long run, it is not impossible for this sword to give birth to a sword spirit. "Elder Gongsun looked at the Traceless Sword with burning eyes, a sword that can reach this level is rare in the world!

Fortunately, the appearance of the Traceless Sword is covered with mottled rust, and ordinary people can't see the uniqueness of this sword, and the rust on the sword seems to have grown together with the Traceless Sword, and it cannot be removed unless it is washed and cast.

"The sword technique is not difficult, as long as you can control your spiritual power to drive this sword and stabilize your body, you just watch. After speaking, Elder Gongsun picked up the Traceless Sword, took a slight leap, and stood on the Traceless Sword.

Elder Gongsun seemed to have an attraction under his feet, firmly absorbing the Traceless Sword, and there was a strong spiritual power on the Traceless Sword.

"Whoosh!" The next moment, I saw the Traceless Sword carrying Elder Gongsun flying forward quickly, and the Traceless Sword was covered with a hazy halo, which was Elder Gongsun's spiritual power.

In the blink of an eye, Elder Gongsun came back, unloaded the Traceless Sword and handed it to Su Yu.

Su Yu took the sword, and there was still Elder Gongsun's spiritual power on the sword, and he clearly felt that the Traceless Sword was indeed absorbing this spiritual power!

"This sword is really absorbing spiritual power!" Su Yu had never paid attention to such changes before, otherwise he would definitely treat this sword well before.

"This is the mantra of the sword, I will teach you now, if there is no mantra of the sword, this sword will not be able to fly. Elder Gongsun stretched out two fingers and put them in front of Su Yu's forehead, and the next moment, Su Yu felt that there was something more in his mind.

"After delaying for so long, I should also go, these three pills are so good that you can save your life in a crisis. Elder Gongsun took out three more jade bottles, and inside the jade bottles were three different colors of pills.

"The disciple thanked the master. Su Yu carefully put away the three bottles of pills, Elder Gongsun's favor is really not small.

"Since you have worshiped me as a teacher, you don't need to thank me, these are all I should give, the old man only hopes that you can return safely. Elder Gongsun looked at Su Yu with kind eyes, he placed high hopes and hopes on Su Yu, I hope that he can take a different path in the future!

"Yes, the disciple knows!" Su Yu nodded, looking at Elder Gongsun's kind gaze, and suddenly felt that Elder Gongsun was escaping after staying in Xiaofeng for so many years, although he didn't know what Elder Gongsun had experienced before, but Elder Gongsun was a powerful figure, and the blows he had suffered were bound to be extraordinary.

Elder Gongsun left, it seemed that he had only taken a few steps, but his figure disappeared quickly, and it was not until he could not see Elder Gongsun's figure that Su Yu found a place to sit down.

"Imperial Sword Technique Formula...... Su Yu clicked the Imperial Sword Technique Formula that Elder Gongsun had put into his mind, read it carefully, and firmly remembered it in his heart, and then this Imperial Sword Technique Formula slowly dissipated.

"Try this sword technique, when you are proficient, we will set off!"

"Okay!" Su Yu responded, looking at the Traceless Sword with burning eyes, he was already familiar with the swordsmanship mantra, and he couldn't wait to try the swordsmanship.

"Spiritual power is the base, the long sword is the auxiliary, the body floats with the sword, and the sword walks......" Su Yu silently recited the sword mantra, carefully controlled the traceless sword, levitated it in front of him, and leaped forward, standing on the sword.

The Traceless Sword was suspended in the air, and Su Yu had a feeling of unsteady standing, his body swayed from side to side, and he carefully controlled the Traceless Sword with spiritual power to maintain the balance of his body.

"Let's go!" Su Yu tried to urge the Traceless Sword forward, the speed of the Traceless Sword was not too bitter, Su Yu didn't dare to be too fast, and he couldn't control it well.

As soon as the Traceless Sword moved, Su Yu's figure shook and unsteadily, as if it could fall off the sword at any time, and it took a long time for the Demon Emperor to stabilize, and gradually, Su Yu was able to control his body on the sword and try to speed up the speed of the sword.

But to speed up the sword, it is necessary to increase the output of spiritual power, the faster the speed of the sword, the more spiritual power is required, realizing this, Su Yu understands why there are not many people in the sword, this kind of consumption is really terrifying!

According to his current strength, if the speed of the imperial sword is a little faster, the spiritual power in his body can support half an hour is the limit, and he can't even fly fifty miles in half an hour.

"No wonder few people fly with the sword, the consumption of spiritual power is too great!" Su Yu stopped the sword, jumped down from the Traceless Sword, looked at the Traceless Sword that seemed to have changed somewhat, and shook his head slightly, but it is better to have the sword than not to have it.

"Su Yu, you are wrong, Elder Gongsun only taught you the sword technique because he actually had other intentions. Seeing Su Yu's appearance, he knew that he didn't understand what Elder Gongsun meant.

"What do you mean by senior...... Master deliberately taught me the art of the Imperial Sword Technique, but it is actually better to cultivate?"

It is true that the sword technique consumes spiritual power, but Su Yu also needs to cultivate spiritual power, if every time the sword runs the spiritual power in his body to the limit, then the meridians in his body will have a sense of hunger, and the spiritual energy absorbed when he cultivates again will definitely be much more, and the spiritual power in his body will be more than before, which is also good for him to improve his strength!

"Yes, this is the biggest benefit of Swordsmanship, in front of it, the so-called disadvantages are not worth mentioning at all, people who used to use Swordsmanship to practice can be seen everywhere, but for some reason it has become so rare now. The machine spirit nodded appreciatively, Su Yu's comprehension is really rare, but it is a pity that today's people regard swordsmanship as chicken ribs.

"I have basically mastered the sword technique, and I will use the sword technique to practice along the way, where do the seniors think we will go next?" Su Yu looked at the machine spirit with a radiant expression.

"Let's go to the Human King City! There's an old guy who hasn't seen you for a long time!" said the machine spirit, looking in the direction of the Human King City.
