Everything has changed.

It turned out that the exit of the secret room had disappeared due to the displacement just now, and the orientation of the entire secret room and the position of each row of drawers were rearranged like a large Rubik's Cube.

Xu Huange was so angry at this moment that he glared at Ye Mujin and said angrily: "Ye Bujin! I just said don't move, don't move, why do you always go wrong?"

"I ...... I just turned it unintentionally...... I didn't expect it to ......," Ye Mu Sumire said aggrievedly.

"Alright, now is not the time to get angry, the main thing for now is to find the exit first. Lin Chuyi slowly got up from the ground and said calmly, and then frowned and glared at Ye Mujin.

Ye Mujin immediately clasped her hands together and smiled at Lin Chuyi and Xu Huange, looking sorry.

Xu Huange sat upright with the slate, glared at Ye Mujin helplessly, and then his eyes inadvertently swept to the lower right corner of the slate, because the slate had just moved violently, most of the dust that had time to be wiped off on the lower right foot had fallen, and a word loomed.

"Princess Chu Yi, whose do you think this secret room belongs to?" asked Xu Huange.

Lin Chuyi shook his head: "I don't know, I've never been here. ”

"I think it's probably Xinyao, look here. Xu Huange wiped the remaining dust on the stone slab in the lower right corner with his hand, and a word slowly appeared - Yao.

"Coupled with the fact that you just said that you have never seen those digital patterns on the slate, it means that these digital patterns only belong to us Ritianji, and I can't think of anyone else except that she carved them. Xu Huange paused and continued: "If I guess correctly, this slate should be used as a table, and it should have been supported before, so it is impossible to lie on the ground like this." ”

"What do you mean by these number patterns, could it have something to do with the Book of Heaven?" asked Lin Chuyi, holding his chin.

"I don't know, now the problem is that the middle pattern of these symbols is missing. Xu Huange wiped the missing part vigorously, only half a diagonal line faintly appeared, some in the upper part, some in the lower half, and it didn't look like a decimal point, I don't know if it was a number or a symbol.

"What number pattern? I'll see. Ye Mu Jin ran over with a grin, "These patterns are so strange, I've never seen them before, I'm sorry, I can't do anything about it." Ye Mujin held her mouth and waved her hand.

"We didn't expect you to see why. Lin Chuyi replied in a disgusted tone, pointing to a series of twisting patterns and asking, "What do these patterns represent in your day?"

"In front and below are the numbers 90 and 15, and in the middle are the three symbols of trigonometric functions α, β, and γ. But what do these numbers have to do with trigonometric symbols?" Xu Huange struggled to recall a series of formulas in high school math, but it was hard to remember them after such a long time.

"What the hell is Xin Yao trying to tell us, what is the missing pattern in the middle?" Lin Chuyi muttered.

"If 90 and 15 are triangle angles, what does it have to do with α, β, and γ symbols?" Just as Xu Huange was thinking hard with his eyes closed, Ye Mujin patted Xu Huange's shoulder with his hand and said with a smile: "Huange, look, isn't this side missing, I made up for it all, you see this symmetry." ”

Xu Huange opened his eyes and saw that Ye Mujin had filled in the missing slashes in the middle of the first four digital patterns to form a symmetrical pattern ">", which looked like a greater than sign.

"Shhh

Ye Mu Jin held back her mouth and said, "Aren't I also trying to find a way for everyone." Then he was about to leave.

"Wait!" Xu Huange said as he stared at the slash line on Ye Mu Jin's patch.

"What's wrong?"

"There's a discovery! Xu Huange pointed to these number symbols and said: "If it is added by Ye Mujin just now, then this hypotenuse has become a symbol in our daily pole, that is, a greater than sign, and it will become 90 > α>β>." γ, if you define it according to the trigonometric function, α, β, and γ are the three corners of a triangle, that is, each angle is less than 90 degrees, and then look at the number 15 below, I think it may represent a difference of 15 degrees between 90, α, β, and γ, that is, 90 degrees minus α is 15 degrees, α minus β is 15 degrees, and β minus γ is 15 degrees. In this way, the sum of all the angles of a triangle is 180 degrees, α is 75 degrees, β is 60 degrees, and γ is 45 degrees, which is exactly the three angles of a triangle!"

There was silence.

"Hehe, I don't really understand what you mean, but it doesn't seem like I'm in trouble. Ye Mu Jin laughed.

"Yes, Ye Mu Jin, it helped me a lot!" Xu Huange smiled at Ye Mu Jin.

"Hehe, I can help. Ye Mu Jin touched his head and smiled.

"That is, it is crooked. Lin Chuyi raised his eyebrows and said.

"Hmph. Ye Mu Jin ignored Lin Chuyi anymore, turned around and asked, "Then what now?"

Xu Huange looked around and gestured with his hand to the surrounding walls: "I think Xin Yao should want us to find the corresponding drawer according to the angle." ”

"When we just displaced, did you count how many times we turned?" asked Xu Huange.

"Three and a half turns clockwise. Lin Chuyi replied.

"Have you counted them all?" Ye Mu Sumire's eyes widened.

"Those who practice martial arts are inherently alert to all dangers. Lin Chuyi replied.

"I believe that everything is born together, we have turned three and a half times, each layer above is staggered, it must also be three and a half turns, with this slate as the benchmark, if everything is reset, all the ring drawers around are tiled into a plane, find a corner of the triangle on the top floor, draw the largest triangle that meets the requirements, and the next two footholds will be in the ......" Xu Huange's brain is running rapidly.

"Princess, can you fly to the top floor and help me find an angle?" Xu Huange asked.

"Yes. I saw Lin Chuyi throw two flying rakes from the two cuffs and fix them on the stone wall on the top floor of the secret room, and then Lin Chuyi pulled the chain of the flying rake hard, stood up, and immediately flew to the top floor of the secret room, and the action was very clean and neat.

"You move slowly to the right first, I'll tell you to stop, you stop. Xu Huange replied.

"Okay. ”

"It's not this, it's not this, it's not this......" Xu Huange's mind was running rapidly, and the tense atmosphere made Xu Huange's forehead break out in a cold sweat.

About ten minutes later, just as Lin Chuyi was exhausted, Xu Huange suddenly said, "Stop! It's this drawer under your left foot, don't open it for the time being." ”

Lin Chuyi nodded, changed the shape of his body, pulled the chain of the flying rake with his right hand, pressed his left hand against the designated drawer, and spread his legs to fix his body.

"Next, Ye Mu Jin, you go to the back of the stone wall first, follow my pace and move forward clockwise, I move clockwise from the front of the stone wall to the right, follow my rhythm, I say let's go together, I say stop and stop together. ”

"Okay. Ye Mu Jin quickly ran to the back of the stone wall.

"Okay, go to a drawer position. Xu Huange closed his eyes, his brain was running rapidly, and the combination of various triangular diagonal lines was drawn in Xu Huange's brain.

"Continue to a drawer position. ”

......

One by one, the cold sweat on Xu Huange's forehead slipped down his temples and slowly dripped onto Xu Huange's clothes.

After walking for about ten minutes, Xu Huange suddenly opened his eyes and shouted, "Stop! Ye Mujin counted the 39th drawer up from the drawer at your feet!"

"Okay, no problem!Princess Chuyi, please borrow a flying rake!" Ye Mu Jin asked Lin Chuyi for help.

I saw Lin Chuyi fly out of his cuffs and set a flying rake on the top stone wall of the drawer on Ye Mu Jin's side, and the flying rake chain slowly fell, just at Ye Mu Jin's feet.

"Awesome!" Ye Mu Sumire exclaimed, and then slowly climbed along the flying rake chain to the 39th drawer.

"Next is me. Xu Huange's hand slowly moved to the drawer he locked, "Are you ready?"

"Are you sure?" asked Lin Chuyi nervously.

"To be honest, I'm not completely sure. Xu Huange paused and said: "Life and death are just a thought, 50% chance, maybe we will survive, maybe we will die." Are you willing to gamble?" Xu Huange frowned, and asked seriously at Ye Mujin and Lin Chuyi in the distance.

"There is no other choice now, I choose to believe you and take a gamble!" Lin Chuyi said firmly.

Ye Mu Jin was silent for a moment, and then smiled: "It's all fate, let's gamble!"

"Okay! I'll count 123, let's turn the key and open the drawer together!" Xu Huange said loudly.

"One, two, three!"
