Long Yun was like this, reciting this number mantra until dusk, and he still hadn't fully mastered it. It's strange to say, he can read those books and cheats, and he can memorize them a few times, but this mantra of mathematics is just a few dozen sentences, and Long Yun just can't remember them all.

Xia Qingyan saw that Long Yun didn't know the essentials for so long, so he had already written those mantras on the ground and let Long Yun understand them by himself, and she had already run away to no one, if she stayed here a little longer, she might be angry with Long Yun's dull brain.

"Forty-seven twenty-eight, forty-eighty-twenty-nine...... No, four-eight-thirty-three......"

Just as Long Yun was painstakingly reciting his math secrets, Su Yusheng finished his cultivation and came to find Long Yun.

Seeing that Long Yun kept talking to himself, Su Yusheng said, "Senior brother, what are you reading in your mouth? Could it be that Master taught you a spell?"

Long Yun looked up at Su Yusheng and said, "What kind of spell is it!" Master is teaching me math, but I can't learn it." After speaking, Long Yun patted his head in annoyance.

Seeing Long Yun like this, Su Yusheng hurriedly smiled and said: "It's getting late, let's go back first, let's practice another day, continue like you, maybe you will be mad by this number technique, and wait for it to spread out, the apprentice of the right protector of the Dharma will be made mad by a 'number technique', then it will definitely kill a lot of people with laughter, hahaha." ”

Long Yun saw Su Yusheng making fun of him, he didn't feel good in his heart, he made up his mind, he must not give up, and he must learn this number of techniques thoroughly......

At night, when he returned to his cabin, Long Yun's mind was still full of those numbers, which made him unable to sleep, he simply got up and sat down, and silently recited these mantras taught to him by Xia Qingyan today over and over again in his heart......

In the next few days, Long Yun didn't do anything, just recited this mantra of mathematics, and the senior brothers and sisters made fun of him from time to time, persuading him not to be a tendon all the time, this exercise was not suitable for him, so he asked the master to change the exercise to teach him.

But Long Yun didn't listen, he admitted the truth of death, and he had to memorize his mantra with one mind.

Xia Qingyan saw that Long Yun was so serious, and it was also difficult to ride a tiger, this "land shrinking Dafa" was what she had to teach Long Yun at the beginning, and now it is impossible to personally tell him not to practice.

Fortunately, the hard work finally paid off, and under Long Yun's persistent and hard work, he finally completely mastered the math mantra that he didn't know anything about before and made him miserable.

When Xia Qingyan assessed him back and forth several times, and he actually answered all of them fluently, Xia Qingyan simply didn't believe it.

"Long Yun, you really impressed the teacher, and thought that you would never be able to get this trick. He also said that he would give up on his own after a while, I didn't expect you to really memorize it all!" Xia Qingyan said to Long Yun in amazement.

Long Yun smiled and said, "Thank you, Master, for affirmation." There's nothing difficult about this, only familiarity. ”

Xia Qingyan said: "Now that you have mastered the mantra of mathematics, now let's try this 'method of shrinking the land' that the teacher told you." ”

Long Yun immediately stood on top of the square, ready to try how this "method of shrinking the land" was.

"Thirty-two!" Xia Qingyan suddenly shouted.

Long Yun listened to the order, calculated quickly in his mind, and said silently in his mouth: "Four-eight-thirty-two, four vertical and horizontal!" While he was silently reciting, the dusty footwork under his feet was running rapidly, and in an instant, he had already flashed to the square that was four vertical and eight horizontal.

Xia Qingyan said again: "Forty-two!"

"Six, seven, forty-two, six vertical, seven horizontal!", he said silently, his figure flashed again, and he split into the square of six vertical and seven horizontal.

"Fifty-four!"

Long Yun's figure flashed again and came to the square of six vertical and nine horizontal.

"Sixty-three!"

Long Yun's figure flashed, and he stood directly on top of the square with seven horizontal and nine horizontals.

Then Xia Qingyan sped up and called out a few numbers in a row: "Seventy-two! thirty-five! forty-seven! eighteen! fifty-six! eighteen! Eighty-one!"

Long Yun listened to the order, and calculated rapidly in his mind, and his body flashed several times, wandering back and forth in the world of these ninety-nine eighty-one squares, his body was like a wind, and his shadow was like a swimming dragon......

He seemed to feel that this huge nine-square grid was just an inch of land under his feet, giving people a sense of pleasure, worthy of the "Great Law of Shrinking the Earth"! Long Yun couldn't help but sigh.

Xia Qingyan was beside him, and when he saw Long Yun's progress, he couldn't help but feel happy for him, and said with a smile: "Okay, very good, come, come to the teacher." ”

Long Yun listened to the order and walked out of those squares and came to Xia Qingyan.

Xia Qingyan motioned for Long Yun to stand beside her, and then with a wave of her hand, a strong momentum swept across the squares just now, sending dust flying all over the ground.

After a moment of silence, after the dust receded, Long Yun looked at the clearing just now, the previous squares were all gone, and now there was only a bare wasteland.

Xia Qingyan looked at this wasteland and said: "In real combat, there can be no real grid on the ground, you must be able to do it in your eyes, but in your heart. ”

After speaking, Xia Qingyan walked to the top of the wasteland and said to Long Yun: "Now look at where I am, you take yourself as a starting point, draw a square in your mind, and then use the 'Land Shrinking Dafa' to move to my side." ”

Listening to Xia Qingyan's words, Long Yun took a deep breath, and then stared at Xia Qingyan's seat, and a huge square with himself as the starting point slowly appeared in his mind, his eyes moved slightly, and his mind was calculating the current Xia Qingyan's position in the huge nine-square grid in his mind.

After a moment of silence, his eyes suddenly froze, and he said, "Eighteen!"

After speaking, his figure flashed quickly, and he quickly came to Xia Qingyan's side, so close to her, that he was about to bump into her arms.

But Xia Qingyan stood there unhurriedly, and when Long Yun's face was about to touch her, she suddenly shook her figure and disappeared.

When Long Yun searched left and right, he found that Xia Qingyan was already behind him.

Xia Qingyan looked at Long Yun from a distance and said, "It's still too slow, come again!"

Long Yun continued to observe Xia Qingyan's position, and in his mind, he used himself as a starting point to re-carve a nine-square grid, this time he reacted much faster, and he quickly judged Xia Qingyan's position in the "fifty-sixth grid". Then he stepped on a series of steps, and quickly came to Xia Qingyan's side again.

Xia Qingyan saw him approaching him again, and he walked lightly without a trace.

In this way, Xia Qingyan kept changing his position, Long Yun kept chasing, their figures flashing back and forth in this wasteland, looking from a distance, like two sparkling waves in the breeze, one fell together......
