Seeing the rising column of water in the direction of the rainbow spring, Xuantian stood in place for a long time, without saying a word, his face was shocked, as if he had witnessed a ghost and a god.

"Why? I can't believe it, if you practice this sword finger to the fullest, you can also have this power. Qingling said lightly.

"Uncle Shi, you made such a big move, won't the head of the sect blame you?" Xuantian finally came back to his senses and wondered.

"Naturally not, I've made a bigger move than this before. Now that I have taught you the cultivation method of the Sword Finger, it is up to you to do the rest. You go to the Falling Thunder Waterfall, cultivate in the turbulent waterfall, resist the torrent with your sword finger, and if you can split the water flow with your true qi, it can be regarded as a slight achievement. The terrain of Falling Thunder Waterfall is treacherous, and no one will easily set foot in it, but it is an excellent place to practice sword fingering. ”

Xuantian waited for Qingling to say that, then knelt down and thanked: "Thank you Uncle for teaching me kung fu, my uncle's teachings and disciples must remember it." It's just that this sword is extremely profound, and the disciple's talent is dull, if he fails to practice the divine skills, I hope to ask my uncle for forgiveness. ”

"No matter how intelligent or dull you are, if you can know how to concentrate and have no distractions, you can achieve it. Besides, your heavenly capital is superior, why do you say this?" Qing Ling's face was serious, and he said in a deep voice.

Xuantian carefully understood what Qingling said, suddenly felt enlightened, bowed down and thanked: "Thank you Uncle for solving the confusion for the disciple, the disciple will definitely live up to the high expectations of the uncle." ”

"That's very good, you can go and cultivate. Qing Ling waved his hand lightly at Xuantian and ordered him to leave.

Xuantian bowed to the ground again and bowed his head to say goodbye, and then went straight to the vicinity of the Falling Thunder Waterfall, and he heard the sound of the waterfall surging like thunder a mile away, which was really shocking.

Xuantian came to the edge of the waterfall, looked at the deep waterhole formed by the accumulation of the waterfall over time, and thought to himself: "If you cultivate here with the help of the art of the imperial sword, you will definitely not make much progress, it seems that you must enter this waterhole." If it weren't for the fact that when I was younger, I used to play in the river outside the town and learn a little about the water, it would have been a bit of a problem. ”

Xuantian didn't hesitate for a moment, and jumped straight into the deep pool. Unexpectedly, the water pressure in the deep pool was very huge, and as soon as Xuan Tianfu entered it, he felt that his body was heavier and heavier, as if Mount Tai was pressing on the top, and he was almost unable to move.

"This Thunder Waterfall is so dangerous, no wonder no one dares to approach it easily. Xuantian thought secretly in his heart.

Seeing this, Xuantian hurriedly raised his qi dantian, and used his true qi to pass through the meridians of the large intestine of his hand Yangming, wanting to temporarily relieve the pressure with the help of the true strength emitted by the sword fingers. Unexpectedly, every time he traveled the qi, the true qi was stuck in the Quchi acupoint at the elbow striation, and he could not take another half step forward. Xuantian tried back and forth more than a dozen times, but not only did he make no progress, but he also consumed little of his energy left. The pressure in the water hit frequently, and Xuantian felt that his body had increased a little more for no reason, and it became very difficult to hold his breath.

"If we continue like this, I am afraid that we will drown here today. ”

Xuan Tian thought about this, and the survival potential hidden in his body exploded instantly, only to see his body leap upwards suddenly, and he actually broke through the pressure of thousands of catties in the water, and reached more than ten zhang above the waterhole. Xuantian saw that this struggle really took effect, and hurriedly used the last bit of physical strength to use light skills to sweep towards the ground by the pool, his feet just touched the surface, and a deep feeling of tiredness suddenly hit, but he felt that his body was sore, his spirit was sluggish, and he fell to the ground and fell asleep.

When he woke up, it was almost dusk, and Xuantian thought that it was obviously foolish to enter the water rashly, and he needed to wait until he fully mastered the method of qi vein operation before he could try it.

Xuantian immediately crossed his legs and entered a state of meditation to relieve anxiety, abandon distracting thoughts, calm his mind, and unite his body and mind.

After the preparation was completed, Xuantian raised the qi dantian and began to penetrate the meridians of the large intestine of the hand Yangming. Xuantian has no desire and no thought at the moment, when the true qi travels to the big acupoint of Quchi that has been unbreakable in the pond for a long time, he has not encountered the slightest obstacle, and has passed smoothly without stagnation, and the subsequent acupuncture points are also broken through one by one, as if walking on a flat road.

A week after Xuantian successfully practiced qi, he did not take pride in victory, but repeatedly lucked through the meridians to ensure that he could do it in one go in the future.

Time passed quietly in the rumbling sound of the falling thunder waterfall, and two hours passed in the blink of an eye, Xuantian slowly opened his eyes, his face showed joy, thinking that the cultivation within these two hours was quite effective.

"Although the power is still weak, it should be able to do as you like. Xuantian muttered to himself.

Xuantian stood up, lifted a breath of true qi, and easily condensed it to the Shangyang acupoint of his right index finger.

At this moment, the airflow within a radius of Xuantian's right index finger was obviously much tighter than Fangcai, and some visible fluctuations between the friction of the airflow were born out of thin air, like fine lines floating on the surface of the water.

Xuantian volleyed into the deep pool three zhang away, only to hear a "snort" sound that broke through the air, and the sword pointed at the true qi straight out and fell into the pool.

The pool of water suddenly rippled in circles, and even saw some slight bubbles emerging from the center of the ripples, and between a few breaths, a clear column of water with crystal waves and flowers erupted from the pool, straight up more than three feet, just like a white fish tumbling and jumping in the cold pool.

Seeing this scene, Xuantian nodded slightly, quite satisfied with the results of his cultivation, and said in his heart: I see that I can re-enter the pool to cultivate from tomorrow, and I will rest first tonight.

There was nothing to say all night, and the next morning Xuantian re-entered the deep pool, with the cultivation of last night, Xuantian easily used his sword fingers, but the pressure in the pool was far beyond Xuantian's imagination. Fang used his sword finger to force a little scattered, and then there was an endless stream of follow-up attacks. When Xuantian finally broke through the encirclement and emerged from the deep pool, his true qi had already been consumed, and even if he was hit head-on by a torrent, his body fell back into the pool.

Xuantian had to struggle out as last time, running the Three Cleansing Heart Method, restoring his physical strength and true qi, and after three hours, Xuantian tried again, but it was still fruitless.

In this way, I tossed back and forth for three days and three nights, and each time the result was the same, and there was no progress in the slightest.

Xuantian calmed down and pondered carefully, and found that he was still in a hurry and didn't know the trick.

"In order to quickly get out of the deep pool and bounce off the falling torrent, you must have deep internal strength. And now I have not opened one of the eight veins of the strange meridians in my body, and my internal cultivation is very low, so I naturally can't resist the waterfall. It is necessary to retreat and practice first, and then make plans after opening up the big points around the body. It's just that if that's the case, then why did Uncle Shi order me to cultivate here in the first place?" Xuantian thought in his heart.

"Wait a minute----" Xuantian suddenly seemed to have an understanding, and immediately used his true qi to try to forcibly break through the starting point of the Yin Dimensional Vein, one of the eight great wonder scriptures---- to build the Bin acupoint, this move is really extremely reckless, these eight great wonder scriptures are the eight lifelines that are the most difficult to get through in the human body, and the true qi will go crazy immediately, and the skill will be wasted.

Beads of sweat continued to drip down on Xuantian's forehead, his brows were furrowed, and his face seemed to be very painful.

After a while, Xuantian suddenly opened his eyes, his complexion gradually soothed, and the flickering essence in his pupils was a little more obvious than usual.

"Uncle Shi is really right, whether it is the water pressure of this deep pool or the rapids of the waterfall, it has the effect of strengthening the muscles and forging the bones, and impacting the acupuncture points around the body. I only experienced five days of training in the pool, and when I penetrated the acupuncture points, it was several times easier, and it seems that this place is really an excellent place to practice internal strength. Xuantian was pleasantly surprised and couldn't help but praise.

After Xuantian found the method of cultivation, he dived into the deep pool during the day and let the water of the pool impact his muscles, bones and acupoints, and at night he concentrated on controlling the true qi to penetrate the many acupuncture points in the eight veins of the Qi Sutra.

Devoted to penance, I didn't realize that time was rushing and time was passing quickly, but I didn't know it.

100 days later, Xuantian has opened up the two veins of Yin Dimension and Yin Stilts, and his internal cultivation has risen greatly, but Xuantian not only did not stop there, but instead took the risk of his life, and sat down on a rock with the most concentrated fall, and his true qi resisted the pressure of 10,000 catties carried by the waterfall. At this time, Xuantian's skill was already quite profound, and he could barely support it for a moment. As Xuantian cultivation deepens day by day, the time for persistence will be extended day by day. This waterfall rapids were very different from the faint impact in the deep pool, and the cultivation process increased tenfold in an instant.

Time is like an arrow, the sun and the moon are like a shuttle, three years in the blink of an eye, like a dream.

At this moment, Xuantian, who was still naked, sitting in the inverted Milky Way, suddenly roared, shocking the four wilds, like a hundred bells ringing in unison, and a hundred beasts roaring together, traversing the miles and lasting for a long time. For a moment, it was enough to overpower the rushing waterfall, which was like the sound of thunder.

Such an astonishing skill can only be practiced by those who have penetrated the two veins of Ren and Supervision.
