The gentleman sent by the formation peak is a second-grade array master, and the badge pattern is an abstract graphic representing the two spiritual roots of gold and water, because it is recognized that the more spiritual roots, the more suitable for learning the formation, but the reality is that there is only one five-grade formation master who is marked with the five elements of spiritual roots in the entire Fengming world, and belongs to the head of the Dongwo Formation Sect, which is famous for specializing in the formation road, Dongwo is actually the name of the place of Dongwozhou, and the small sect has grown little by little to become the top of the formation, and it has made Dongwozhou a holy place that the formation masters yearn for, and the formation division alliance is the backstage of this sect.

Lu Xiaoman looked at this formation master curiously, his eyes were half-drooping, and there were heavy dark circles under his eyes, which was rare to see, the black circles under his eyes were like this, how many nights had he stayed up, and there were actually such monks who didn't care about their own image.

The other party glanced coldly at the sparse classroom, his eyes did not linger on the three people in the first row, as if they were treated equally, and then introduced himself in a voice that seemed to have not woken up.

"My surname is Xu, my name is Xu Jinxue, you can call me Uncle Xu, now according to the usual practice, test your arithmetic ability first."

After speaking, Xu Jinxue raised his hand, and several large scrolls flew out of his sleeves and landed on everyone's table accurately.

Lu Xiaoman put the pen and ink in place, while browsing the volume, sweeping it at a glance, it was all so simple that you don't need to use your brain, she picked up the pen and dipped it in ink and wrote the answer directly, in one go, and then put the pen down.

"Uncle Xu, I'll hand in the papers."

"Huh?!"

Lu Xiaoman's voice startled all the other disciples who were thinking hard, He Feng and Chu Rui also looked at him in surprise, especially Senior Brother Bingshan, it was really rare to have an expression, Lu Xiaoman looked left and right, only their names were written on their papers, and they were still fiddling with calculations at hand.

Xu Jinxue came down from the podium slowly, and Lu Xiaoman saw that a timekeeping incense stick had just been lit on it, and only one pointed tip was burned, and she finished answering the paper in her hand.

"You are Lu Xiaoman?" Xu Jinxue picked up the scroll, looked at the answer first and then the name, and then put the scroll into his sleeve.

"Yes, Uncle Shi, I'm Lu Xiaoman."

"Make another one."

Xu Jinxue took out two dense large volumes and handed them to Lu Xiaoman, turned around and returned to his seat to close his eyes and recuperate.

Lu Xiaoman habitually reviewed all the questions first, and found that the difficulty of these two sheets was directly doubled compared with the previous one, but it was still very simple for her, while reading the question, she had the idea of solving the problem in her mind, she didn't need to dig out the scratch paper, all calculations relied on mental arithmetic, and the two large volumes were all written, and the incense sticks on them were burned less than a quarter.

"Uncle Xu, I'll hand in the papers."

Lu Xiaoman sighed softly, once again breaking the quiet atmosphere in the classroom, and many disciples sitting in the back couldn't help but complain loudly that their train of thought was interrupted, He Feng and Chu Rui were not affected this time, they still lowered their heads to make their papers, and their hands were also very stable, they had heard that Lu Xiaoman was good at calculation in the past few days, and now they have seen with their own eyes how powerful she is, so they will not be shocked again, there is an excellent formation master in sword cultivation, and everyone benefits.

Xu Jinxue walked down, and after reading Lu Xiaoman's scroll, he still didn't say whether it was right or wrong, he directly put it into his sleeve, and then took out the third scroll, only a piece of paper, and there was only one question on it.

Lu Xiaoman glanced at the question and widened his eyes, this is a formation-breaking question, and it is the last very big question in the mathematics, physics and chemistry exam, and the gap between outstanding students and ordinary students is in this big question.

This kind of problem can't be solved directly by mental arithmetic, so Lu Xiaoman put the scroll aside, took out scratch paper and a thin charcoal strip and began to scribble and write.

Xu Jinxue, who was on the podium with his eyes closed, peeked at Lu Xiaoman, closed his eyes and continued to recuperate.
