Tang Xin'er was slightly surprised, she was talented and intelligent since she was a child, not only proficient in martial arts, but also quite dabbled in arithmetic, Qimen Dunjia and the like, and she couldn't see the solution to this formation, but this young man from a miscellaneous servant thought of a way to break the formation?

After a pause, he said, "Since Childe knows the solution, it's okay to give it a try." Pen "Fun" Pavilion www.biquge.info"

Qin Shu said, "But if it's wrong, we may instantly turn into a roasted pig's head." ”

Tang Xin'er smiled faintly and said, "Now that you have entered this formation, it is a life-and-death fight, so what is there to worry about." ”

Qin Shu nodded, "That's good! ”

Taking the characters on the ground as the center point, Qin Shu stuffed two and four stones into the grooves on the doors in the northwest and northeast directions, then six and eight stones into the doors in the southwest and southeast directions, three and seven stones into the left and right doors respectively, and nine and one stones into the upper and lower doors respectively.

When the last stone was stuffed in, there was a sudden tremor in the hole, and a large amount of dust began to flutter and fall.

"I'm wrong?"

"It's over, it's over!" Qin Shu thought that the hole was about to collapse, and immediately hugged his head and scurried to find a place to hide, but the house was empty and where was there a place to hide?

Tang Xin'er glanced at Qin Shu lightly, a trace of disdain flashed in her eyes, and she stood up with an indifferent expression.

At this time, a loud bang was heard, and a door in the northeast collapsed, revealing a passage. At the same time, the tremor suddenly stopped.

"Success, success?" Qin Shu swallowed his saliva with a "grunt", and looked at the passage in a daze, and it took a long time to recover his strength. I wanted to stand up, but I fell to the ground with a pop, and then I found that my legs were already scared and weak.

This one...... It's a little embarrassing!

He coughed lightly and weakly explained, "Hey, I just got my foot down." ”

Tang Xin'er didn't have a special expression on her face, she just walked to Qin Shu's side lightly and stretched out her jade hand to help him up.

In order to save the last face, Qin Shu stood up against the wall.

"Ahem... That's what, it's good that it's not too serious. It's okay...... It's okay. ”

The two of them walked into the passageway, and after a few steps, they came to a room. This room is bizarre, consisting of three walls, each with a door and a groove.

Qin Shu took a closer look and found that the three walls were in a right triangle. Two of the doors on the straight side had been filled with stones, one with six and the other with eight, except for the one on the hypotenuse.

Qin Shu immediately laughed in his heart, thinking that it was some great formation, it turned out to be a geometric body.

It is known that the two straight sides of a right triangle are six and eight respectively, and the length of the hypotenuse is to be found.

It turns out that this "Nine Heavens Qiankun Cave" is just a formation of some simple math problems, as long as you solve these math problems, you can get out. These questions may be extremely difficult in the underdeveloped Dragon Soul Continent, but for themselves, they are only at the level of primary school students.

In this way, my highlight moment is coming! Such a good opportunity, if you don't pretend to be a perfect X, how can you be worthy of your math teacher?

After brewing his emotions, Qin Shu showed a dignified look and said to Tang Xin'er, "Miss Xin'er, do you know this formation?"

Tang Xin'er shook her head and said, "Although Xin'er has seen a lot of strange formations in books, she has never seen such a strange formation. ”

Qin Shu sighed and said, "I have heard this formation mentioned by a master, he said that it is called the 'Pythagorean Xuan Array', and the master also said that he has spent his whole life trying to crack this formation, but he has never been able to get the rules. ”

Pretending to be X, how can there be less foreshadowing? Storytelling has to be suppressed first and then promoted? When she stands up again when she is desperate, she doesn't believe that this time she can't move the heart of the big beauty.

"Pythagorean Xuanjing?" Tang Xin'er raised her eyebrows slightly, "What a strange name, it's really unheard of." I don't know how you got acquainted with that master, and if he can't solve it, I'm afraid we will ...... too."

Qin Shu nodded and said in a deep voice, "That's right, it seems that this time it is really more auspicious." At that time, the master said that I was gifted and a genius that could never be found, and said that I was probably the only one in the world who could solve it. Hey, in fact, it's just a joke of the master, how can I compare with his old man? He can't solve it, and I can't solve it. ”

Ahem...... I seem to be a little too boastful when I am excited? But this is not shameless, is it? After all, I haven't said that I know astronomy, geography, arithmetic and so on, and I am already very low-key.

Tang Xin'er said lightly, "Okay, it's all up to fate." ”

After being silent for a while, Qin Shu said again, "No matter what, you still have to try." I don't have anything to worry about, but what if I die? And Miss Xin'er, you are different, you haven't said goodbye to your sweetheart, you must be very unwilling, right?"

Tang Xin'er said calmly, "Childe, don't talk nonsense, if you want to try, try it." If she can go out, Xin'er will be happy. If she can't get out, Xin'er has nothing to be unwilling to. As long as her father and several brothers are safe, Xin'er will be satisfied. ”

After a pause, Tang Xin'er said again, "Qin Gongzi, Xin'er has misunderstood you before, don't be surprised." ”

This was a bit unexpected for Qin Shu, and he was also happy in his heart, and said with a smile, "Yo, you will also apologize?" With Miss Xin'er's words, even if I die, it's worth it. ”

Collected his emotions, then picked up a stone and wrote a bunch of formulas on the ground. I wrote all the right triangle hypotenuse law, Newton's first law, the second law, and so on, and soon the ground was full of English, Arabic numerals, and mathematical symbols, which looked mysterious.

Tang Xin'er Rao was well-informed, and she had never seen so many strange "runes", so she couldn't help but ask, "Childe, where did you learn these runes?" ”

Qin Shu said seriously, "It was the master who taught me." I met that master by accident in the woods, and when he saw that I was intelligent, he spent seven days and seven nights teaching me a lot of things. From astronomy to geography, as well as arithmetic metaphysics, the method of planning, and the way of ghost schemes, it is said that he taught me everything he has learned all his life. But I'm just a child, how can I remember so much, so in the end I just learned the surface. ”

Tang Xin'er shook her head slightly when she heard this, and said, "Childe is too modest." Although the son does not know martial arts, but Wen Taowu has the style of a master hermit, I think the master is not mistaken, in just seven days, the son has indeed learned a great skill. ”

Qin Shu knew that Tang Xin'er would never say some polite words against her will, since she said so, she must have thought so, and her heart was suddenly overjoyed. Martial arts are not enough IQ to make up, it seems that the girls on the Dragon Soul Continent also eat this routine!
