Seeing that Tian Xu was serious, Ziyan was no longer shy, but she still asked suspiciously, "Is it really possible?"

Tian Xu said: "Actually, even if you take off your clothes, I have to build a formation around you to reduce the resistance of the water, otherwise, the speed will be unbearable." ”

Ziyan was still not at ease, and said: "I heard what you said seems to be very powerful, you go down and swim for me first, so that I can be prepared, and I don't know what to do if I get in the water." ”

Tian Xu said: "Okay, I'll swim around first and you can take a look." As he spoke, he jumped up from the spot and plunged headlong into the water.

Instead of switching to the usual gill breathing mode, he used the method he had just learned to use the formation method to filter oxygen from the water, and while swimming underwater, he released a string of bubbles, so that Ziyan could clearly see his flickering figure underwater.

This was the first time he had gone into the water with his clothes on, and after using a formation to isolate his clothes from the water, it was not much different from taking off his clothes and swimming. But he was used to direct contact with the water, and after putting on his clothes at this time, the resistance did not increase significantly, but his swimming movements were somewhat affected, making him a little slower than usual.

In addition, there is another thing that makes Tian Xu feel unaccustomed to wearing clothes, that is, after isolating the contact between the body and water, the olfactory imaging cannot adapt to it for a while, which makes him feel that the sensitivity of the body's senses has decreased a lot, which is quite uncomfortable.

Fortunately, this discomfort is more psychological, and after swimming for a while, this problem does not exist.

He felt it carefully, and found that the most obvious effect on his swimming movements was the jade soft sword used as a belt around his waist. After putting away the Qingyu soft sword, his waist was completely released, and it was really much more comfortable to swim again, and his speed was close to usual.

He knew that the jeans he wore on his legs actually had an effect, but he was worried that Ziyan would not be able to adapt to him taking off his pants, so he could only overcome this discomfort.

In fact, with his current realm, the green jade soft sword with his waist has little effect on self-defense. But when he was just roaming the rivers and lakes alone, this soft sword had made great achievements several times, killing the enemy and protecting his safety. This green jade soft sword was left to him by his father, and as a commemoration, he usually carried this soft sword around his waist, which has formed a habit.

After swimming for a while and proving that the newly created breathing pattern was completely feasible, he couldn't resist switching to the gill breathing mode before going ashore. When Xun's cold and clear water rushed into his body, Tian Xu let out a long howl with nostalgia and happiness. It's just that this howling sound was emitted in the form of aura oscillation under the water, causing a circle of splash to bloom on the nearby water surface.

He swam near Ziyan, suddenly accelerated and flew from the water into the air, a stream of water sword spat out of his mouth, his body flipped two somersaults, and gently landed beside Ziyan, and his whole body, except near his mouth and nose, was dry.

"How's it going, isn't it? Let's take you for a swim, and I'm sure you'll like it the first time. ”

Ziyan couldn't help but feel itchy when she saw Tian Xu swimming in the water, and saw that his clothes weren't wet at all, so she said, "Okay, but why is your mouth wet?

Tian Xu smiled and said, "Don't worry, I won't choke you." My mouth and nose are wet because I don't breathe the same way you do, I can filter the water like a fish to breathe, otherwise how could I think of a way to let you breathe underwater?"

Tian Xu asked Ziyan to pull her long hair back behind her head, and then took off the earthy yellow robe characteristic of the Kunlun School, leaving only the usual clothes inside, took off her shoes, changed her into a pair of fins for swimming, and jumped into the water with her.

When he first entered the water, Ziyan was obviously a little nervous, and his hands hugged Tian Xu's waist tightly, making it difficult for Tian Xu to swim. Later, perhaps he found that his breathing was not affected as if he was on the ground, and the clothes on his body were not soaked, so he gradually became bolder, and began to try to let go of Tian Xu and swim in the water by himself. It's just that her swimming movements are very stiff, and she can often only spin in one place without Tian Xu's help, and it is difficult to adjust her body posture.

Tian Xu carefully guarded her side and instructed her in swimming, and after more than half an hour, Ziyan finally mastered some regular swimming skills and was able to slowly move in the direction she wanted.

Anyway, learning to swim is quite easy without breathing problems. The density of the human body is about the same as that of water, and there is not much resistance to floating and diving, and the only disadvantage may be that people are not streamlined, and the resistance of swimming in the water is much greater than that of native aquatic animals, and it is not easy to reach high speeds.

After Ziyan swam by herself for a while, Tian Xu taught her how to use her aura to move forward. This method is not the patent of the Ning Dan Realm, and the Qi Gathering Realm can also be used, but it is limited by the total amount of aura and the ability to control the aura, and the efficiency of urging is far less than that of the Ning Dan Realm.

Tian Xu's breathing formation condensed for the purple smoke, as well as the aura shield isolated from the water, all needed to be mastered and controlled by him personally in order to operate normally. With Tian Xu's control ability, as long as the purple smoke is no more than ten meters away from him, it will be very easy, if it is farther away, it will gradually become difficult, and after more than 15 meters, he will be a little uneasy.

This made Tian Xu very distressed, Ziyan still couldn't leave his own protection to swim. Judging from his experience, if he didn't reach the Ning Dan, he would not be able to completely solve this problem with the ability to comprehend and control the aura in the Qi Gathering Realm, and it seemed that he could only really learn this trick of his after the Purple Smoke Ning Dan.

Ziyan himself was not satisfied with moving under Tian Xu's support, so he proposed to Tian Xu to try to swim by himself. Tian Xu asked her: "But if you swim by yourself, how can you solve the breathing problem and waterproof problem?"

Ziyan had already figured out a way for herself, and said, "I can hold my breath for about fifteen minutes at a time, and it's a big deal to get out of the water every few minutes to change the air, it shouldn't be a problem, right?"

Tian Xu groaned and said, "That's okay, but if I remove the protective formation, your body will be soaked in water, and you have to learn to get used to this feeling." In addition, now the waterproof shield on your body also provides you with a streamlined fairing, and reduces the resistance when you swim, after I remove the shield, the clothes on your body will bring huge resistance to your swimming, and the speed will slow down a lot, so be mentally prepared. ”

Ziyan nodded and said, "I know, if you don't try, how can you say that you have learned to swim?"

She asked Tian Xu to send her to the shore, saying that she was going to change her clothes, and drove Tian Xu out far away, and when Tian Xu found out from the water in the distance, Ziyan was already swimming in the water, and when she returned to her, she was already playing happily.
