Seeing Wen Yiyang struggling to control his body on the violently shaking lotus leaf on the surface of the stream, the white-bearded old Taoist said worriedly: "Little Taoist priest of Putuo Mountain, you should think of a way, if the lotus leaf you turned out with a spell is overturned by the torrent, the life of that little Taoist priest of the Zhengyi Sect will be in danger, and I don't know where he will be washed by this torrent at that time." ”

At this time, Yu Fei'er was also as worried about Wen Yiyang's safety as the white-bearded old man, so he desperately thought of a way in his heart, but he really couldn't come up with any good way to help Wen Yiyang get out of trouble for a while. Just when Yu Fei'er was helpless, his eyes inadvertently fell on a few clumps of reeds that were washed away by the torrent on the opposite side of the stream, and his heart suddenly lit up, and he hurriedly comforted Wen Yiyang loudly: "Brother Yiyang, hold on, Yu Fei'er has already come up with a good way to help you get out of trouble." All you have to do is keep an eye on the whirlpool closest to you, and when a pinch of reeds is caught in the whirlpool, you immediately cast your immobilization spell on the reeds in the whirlpool. As soon as your Immobilization Charm is cast, I'll cast a spell to help you jump onto the reeds in that maelstrom. As for what will be done after that, I'll tell you when the time comes. After saying that, Yu Fei'er condensed his luck and began to cast a spell.

"What? Jumping on the reeds in the whirlpool?Yu Fei'er, I heard you right, right?" Wen Yiyang listened to Yu Fei'er's words, and his head, which had been shaken by the lotus leaves shaking under his feet, became even more muddy.

Seeing that the lotus leaves he had turned out might be overturned by the torrent at any time, Yu Fei'er couldn't care about explaining to Wen Yiyang. He quickly squatted down his body, then spread the five fingers of his left hand and pressed against the stone he was standing on, while the fingers of his right hand quickly formed a Dao finger and stood in front of him, continuing to control the five elements qi that he had previously punched into the bottom of the stream. As the Five Elements Qi at the bottom of the stream reached the other side of the stream, the reeds growing on the bank were instantly activated, and they jumped out of the soil on the shore one after another, drawing arcs in mid-air and then all landing around the whirlpool not far from the front of Wen Yiyang.

It seemed that Yu Fei'er had used the power of his earth control technique to the point of perfection, otherwise all the reeds of different lengths that popped out of the soil on the shore could not have all landed around the whirlpool closest to Wen Yiyang. The reeds immediately spun in the direction of the whirlpool's rotation as they landed around the whirlpool, and slowly converged towards the center of the whirlpool, where it seemed that some force was pulling them. Under the influence of this mysterious force in the whirlpool, all the reeds were twisted into a long rope around the edge of the whirlpool, and finally formed the exact same shape as the whirlpool on the edge of the whirlpool. As the swirling reed belt enters the center of the whirlpool, the long reed band immediately turns into a spiral in the center of the whirlpool.

Seeing that the long reed belt was about to be swept to the bottom of the water after being turned into a spiral in the center of the whirlpool, Yu Fei'er hurriedly reminded: "Wen Yiyang, quickly cast your immobilization spell on the reed belt in the center of the whirlpool. ”

At this time, Wen Yiyang already held a talisman painted with a fixation spell in his hand, and after hearing Yu Fei'er's reminder, he didn't think much about it, and immediately threw the talisman in his hand at the reed in the center of the whirlpool in front of him, and at the same time recited the incantation in his mouth: "Heavenly Spirit Spirit, Earth Spirit Spirit, the fixed ancestor is coming, say not move, don't move, can't lift your hand, can't twist your waist, and don't shake your feet into the ground, I sincerely ask the six stars of the Southern Dipper, the seven stars of the Big Dipper to help, I am in a hurry like a law." ”

As soon as the spell came out, the talisman thrown by Wen Yiyang immediately turned into a "Ding" word, and fixed the reed belt that was about to be swept into the bottom of the water in the center of the whirlpool. Wen Yiyang just wanted to open his mouth to ask Yu Fei'er what he should do when he came down, and Yu Fei'er had already heard a shout in his ears: "Get up." A strong force immediately came from the lotus leaf under his feet that was transformed by Yu Fei'er's spell, and his entire body was violently lifted out.

This time, Yi Yang had no choice at all, so he had to jump on the reed belt fixed in the center of the whirlpool. When his feet landed on the reed belt, Wen Yiyang only felt that his feet sank, and then his whole body began to sink rapidly towards the bottom of the whirlpool. "Oh no! Yu Fei'er must have missed something, how could this little reed bear my weight. Judging from the current situation, I have no possibility of escaping this vortex, and it seems that I am really in danger this time. Just when Wen Yiyang was flustered, a powerful recoil force suddenly came out from the reed belt that was compressed into a ball under his feet, instantly pushing Wen Yiyang's body out of the vortex and then jumping into the air.

When his body was pushed out of the whirlpool to reach the highest point above the stream, Wen Yiyang immediately turned over and returned to the stone where Yu Fei'er and Whitebeard Lao Dao were standing. After his body stood firm on the stone, Wen Yiyang finally breathed a sigh of relief, and at the same time, his mind began to recall his entire process of getting out of trouble. Thinking of the thrilling place, Wen Yiyang still felt palpitations, and from time to time he could see water droplets on both sides of his face sliding down his cheeks, and then dripping from his chin to the stones under his feet, and he didn't know if the water droplets on his face were brought down from the water wall just now, or if the previous series of dangers made him break out in a cold sweat, maybe both.

After some reflection, Wen Yiyang's heart was more in doubt than fear, so he looked at Yu Fei'er with wide eyes and asked, "Why did a powerful force suddenly come out of this small reed belt and push me into the air? Could it be that all this is really in Yu Fei'er's calculations? Brother Dao, explain to me quickly, what kind of method did you use to help me get out of trouble this time?"

Yu Fei'er immediately explained with a smile: "Previously, due to the urgency of time, Yu Fei'er didn't have time to explain to Brother Dao. Brother Dao now asked why this seemingly inconspicuous reed belt suddenly erupted with a powerful force? ”

"My immobilization spell?" Wen Yiyang looked dazed.

"It all starts with some secrets in the maelstrom. "We know that whirlpools are only created in flowing water, and that calm and motionless water does not produce whirlpools. When a whirlpool is generated, the closer you get to the center of the whirlpool, the greater the velocity of the water, and when the velocity of the water in the center of the whirlpool is so large that it will even form a space in the center of the whirlpool. Don't underestimate this space, legend has it that there is a sect in Shu Mountain that specializes in cultivating sword spells, and its disciples can not only fly with qi and sword, but also use sword qi to kill the enemy invisibly. Legend has it that they used the special space in this whirlpool to create this kind of sword qi that kills people invisibly, but this kind of swordsmanship of theirs can create such a space in the air, so they also named this swordsmanship of their own vacuum. ”

"Little Taoist priest of Putuo Mountain, the kind of person you are talking about should be a swordsman from Shushan, right? Is there really such a sect in this world? These things you said may be made up by those people who sing operas, and they are not credible. The white-bearded man seemed to be extremely unconvinced by what Yu Fei'er said.

Yu Fei'er said again and again: "What the old gentleman said is that the rumors about the swordsmen of Shushan are also heard from those pilgrims who came to Putuo Mountain to worship incense, don't take it seriously, let's talk about returning to the whirlpool." ”

Wen Yiyang, who heard half of it, stopped doing it now, and he grabbed Yu Fei'er's previous topic and asked again and again: "Brother Dao even knows exactly what kind of spells the swordsmen of Shu Mountain will cast, how can he not know if they really exist in this world? ”

Seeing that Wen Yiyang was unrelenting, Yu Fei'er rolled her eyes and replied: "The rumors about the Shushan swordsman may be made up by some boring people as this old gentleman said, because no one has ever seen the existence of his disciples for thousands of years. As for why these rumors can describe the spell of the Shushan swordsman so well, it is because the person who made up this rumor cleverly derived the vortex he knew into the air, and then made up the Shushan swordsman, a spell that can kill people with sword energy, and even more importantly, this person also gave this spell a decent name, making the whole rumor sound more realistic. ”

"What kind of mystery is hidden in this little whirlpool?" Wen Yiyang asked.

When Yu Fei'er first heard these rumors, she was just as curious as her current Dao brother. With curiosity, Yu Fei'er began to look for information about the swordsmen of Shushan in the ancient books of the sect. After flipping through a large number of ancient books in the sect, Yu Fei'er did not find any information about the Shushan swordsman in these books, but in these ancient books, he found a few books about the ancestors' cognition of the whirlpool, and in these books, they all mentioned an ancient book called "Hetu Shimeng Chapter", but unfortunately Yu Fei'er searched all the places where the books could be stored in the sect and did not find the existence of this book, but Yu Fei'er still summarized some mysteries in the whirlpool in these ancient books. ”

"Brother Dao, come and listen. Wen Yiyang couldn't wait to urge.

"I don't know what kind of theory you, the little Taoist priest of Putuo Mountain, will say?" the white-bearded old Taoist also showed strong interest.

"Yu Fei'er doesn't know if these theories about the vortex that he has summarized are right, since the two of them are interested, then Yu Fei'er will be ugly. As mentioned earlier, the speed of the water in the whirlpool is different, the closer to the center of the whirlpool, the greater the speed of the water, but the greater the speed of the water, the lower the pressure, which creates a pressure difference between the center of the whirlpool and the periphery of the whirlpool, and this pressure difference will push anything that falls into the whirlpool to the center of the whirlpool and press it to the bottom. Therefore, the reed belt that we see is drawn into the center of the whirlpool not by the huge pulling force from the bottom of the water, but by this huge pressure difference in the whirlpool. As for the magnitude of this pressure difference in the whirlpool, it is determined by the speed of the water flow, and the greater the speed of the water flow in the center of the whirlpool, the greater this pressure difference in the whirlpool. When the water velocity in the center of the vortex is so large that it breaks through a certain critical point, a near-vacuum space is formed in the center of the vortex, and the pressure difference in the vortex is infinitely amplified in this space. It can be seen that the caster used air to create a whirlpool, and then used the pressure difference in the whirlpool to produce a huge amount of power in the space in the center of the whirlpool to kill people invisibly, which really makes sense in theory, and it can also be seen that the person who made up the rumors of the swordsman of Shushan used a lot of thought. After understanding that there is such a pressure difference in the whirlpool, it is much easier to explain Yu Fei'er's method next. Yu Fei'er asked Brother Dao to cast a fixation spell to fix the reed belt in the center of the whirlpool, the purpose was not to fix the reed belt, but to fix the pressure difference in the whirlpool on the reed belt. When Brother Dao jumped onto the reed belt in the center of the whirlpool, the spiral-shaped reed belt at this time would inevitably squeeze down from top to bottom after being subjected to gravity. In this process of continuous squeezing from top to bottom, the power that was set in the reed belt by the Daoist brother with spells will be gradually amplified as the reed belt continues to squeeze. When the amplifying power in the reed belt was so great that it exceeded the maximum power that Brother Dao's immobilization spell could withstand, the immobilization spell was immediately released from the reed belt. As the power that had been accumulating in the reed belt was instantly released, the next scene appeared, that is, Brother Dao was bounced high into the air by the reed belt under his feet. ”

"I didn't expect this little reed to burst out with such a powerful power, but what surprised Wen Yiyang even more was that Brother Dao's calculation could be so fine, aren't you afraid that this small reed belt will not be able to withstand this pressure difference in the whirlpool?"

Yu Fei'er replied confidently: "Brother Dao, don't underestimate this reed, in Buddhism there is an allusion to 'Bodhidharma crosses the river with a reed'. Legend has it that the preaching of the Mo in the south has been completed, and when he returns, he encounters a river with no boat to cross, folds the reeds by the river, throws them into the river, and crosses the river by stepping on the reeds, which shows that this small reed is full of toughness. ”

The middle-aged Taoist who was standing on the opposite stone was extremely shocked after hearing that Yu Fei'er used such a clever method to help Wen Yiyang escape from his spell, but he quickly calmed down, and took advantage of Yu Fei'er and the three of them to say a word, waved the seven-star sword in his hand, and then held the sword in both hands and stood it on his chest, chanting words in his mouth and secretly casting the spell.

After the incantation in his mouth was finished, the middle-aged Taoist elder shouted angrily at Yu Fei'er: "Little Taoist, don't be too complacent, my spell has just begun, and the power is still to come, I want to see how you can crack my next spell." After speaking, he raised the seven-star sword with both hands and stabbed it at the stone under his feet. When the tip of the seven-star sword in his hand was about half an inch away from the stone under his feet, he suddenly stopped, and shouted loudly: "Turn." ”
