Immediately afterwards, Ouyang Liuyun tapped this place rhythmically.

A total of seven   , four long and three short, followed by a bang, the bluestone slab moved away automatically, and a big hole suddenly appeared on the ground.

  Ye Feixu opened his mouth in a weird manner: "It turned out... it really opened."

  He took out the fire fold from his arms and lit it. The fire light illuminated the surrounding darkness, and then he found that there was a long corridor inside.

  The corridor seems to be very long, the inside is dark and it is not really seen, and there is a strange smell everywhere.

   Ye Feixu waved his hand, fanning away the musty smell of sex. Ye Feixu's body shrank, then turned to look at Ye Feibai's indifferent face: "Second brother, there won't be any ghosts here, right?"

  Yefeibai’s lips tick slightly: "If you dare not go in, then go back."

  Speaking of it, it is an eventful period. They need this treasure very much. Now that it is here, there is no reason to shrink back. Besides, even if there are no treasures in it, it is considered an adventure.

  Thinking about this, Ye Feixu took the lead in entering.

  The three talents just stepped in, and the bluestone slab above their heads slowly closed again.

  Hearing the dull voice, Ye Feixu felt a little panic in his heart.

  The stairway is very long, about fifty or sixty steps. After walking the stairway, you find that there is a long secret road in front.

   Ye Feixu became more and more worried as he walked around, and couldn’t help asking: “Will we get in and can’t get out...”

  As soon as his voice fell, he heard Ouyang Liuyun yelling, and then countless torches lit up in the entire secret tunnel in front of him.

  The sudden sight of Ye Feixu was terrified, and then I heard Ouyang Liuyun laughing: "I just touched a mechanism. Seeing your timid appearance, what treasure are you looking for!"

   Ye Feixu wiped the cold sweat on his forehead, and he was about to fight with Ouyang Liuyun: "Ou, Yang, Liu, Yun!"

   "Okay, shut up!" Ye Feibai looked at them a little helplessly, suddenly there was a thought that you two are not as sensible as my two sons.

  Ouyang Liuyun saw that Ye Feixu would continue to attack himself, and raised his brows: "I tell you, in case we touch any mechanism here, it won't be good, then we may really not be able to get out."

  Ouyang Liuyun is an expert in this area, Ye Feixu had to believe him, he snorted: "Go out and settle accounts with you!"

  The three of them continued to walk forward, surrounded by smooth stone walls, nothing else.

  They saw that the entire secret road had come to an end, except for the stone table in front, but there was nothing.

  Ye Feixu looked around and curled his lips in disappointment: "Che, I thought there was really a treasure, it's just a mystery! Is this a treasure?"

   Ye Feixu stepped forward and knocked on the table: "A stone, a real stone. A stone table, a teapot, two teacups... Is this the so-called treasure?"

   Ye Feixu was so disappointed, he picked up the two teacups on the table at random and threw them in his hands indiscriminately.

  "Be careful!" Ye Feibai's voice.

   "Put it back!" Ouyang Liuyun's voice.

  The voices of the two people are the same.

   Ye Feixu heard that there was something wrong with the two of them, and quickly put the cup in his hand back to the place. At this moment, dozens of sharp-edged weapons were shot from which direction, emitting a faint cold light.

  Yefeibai's phoenix eyes narrowed slightly, with a touch of solemnity on his face.

  His body leaped up quickly, his sleeves fluttered, his hands were as fast as lightning.

  He condensed all his power into the wind, and a palm wind containing violent power swept toward these sharp blades.

  His movements were too fast, Ye Feixu barely saw how he took action, he heard the sound of a sharp blade falling.

   Ye Feixu seemed a little unresponsive and came over and patted his chest: "It's dangerous!"

  Ouyang Liuyun picked up a sharp blade from the ground, and looked at him angrily: “There are many organs here. If it weren’t for the quick response just now, we were all beaten into sieves!”

Ouyang Liuyun pointed in various directions to show him: "Look here, and here... If you continue to touch the switch, hehe, thousands of hidden weapons will be shot at us, even if there are ten non-white I can't save you."

   Ye Feixu's face turned pale: "So serious?"

   "Nonsense!"

   Ye Feibai frowned slightly: "Is this mechanism on the table?"

   "Yes." Ouyang Liuyun breathed a sigh of relief and smiled, "These mechanisms have been played a few years ago. Fortunately, they are not unfamiliar."

  After he stepped forward, he put the teacup and teapot on the table, and moved them in a regular order, out of a complicated pattern.

  Next, I found that the stone wall in front was slowly opened.

  However, after this stone wall was opened, there was another stone wall behind it.

   Ye Fei Xu said: "Look, there is something on the rock wall!"

  I saw that there were ninety-nine-eighty-one grids on it, some of the grids had corresponding points, and some of the grids were blank.

   Ye Feixu was completely dumbfounded: "What is this?"

  Ye Feibai stood in front of the stone wall, his eyes were confident and proud, and his whole body exuded a dazzling glow: "Sudoku."

The Sudoku board is a nine-square, and each square is divided into nine small grids. In these eighty-one grids, there are already certain numbers and conditions for solving the problem. Then through logical reasoning, fill in 1-9 in the other blanks. So that these nine numbers appear only once in each row, column, and house.

  This kind of gameplay is simple, but the number arrangement is ever-changing.

  Ouyang Liuyun's expression of joy just disappeared without a trace, and his face changed: "It's not white, it's not good...Time is counting down...If this problem cannot be solved within a stick of incense, the entire stone chamber will collapse."

Ye Feixu followed Ouyang Liuyun’s sight and saw that the stone wall was pressing down in a slow state. He was a little annoyed at this moment that he insisted on coming in: "This question looks so difficult, and Can't it be solved in a moment? Why don't we withdraw first?"

  Ouyang Liuyun shook his head with a wry smile: "The road behind has been blocked."

  As soon as Ouyang Liuyun's voice fell, Ye Feibai had stretched out his hand to make three dots in a blank grid. His inner strength was deep and his movements were chic and clean.

  Fingers fell into the hard rock wall, and there was powder falling down continuously.

  It seems that he is standing forward, a strong aura exuding all over his body.

   Ye Feixu's eyes widened: "Second brother, are you sure you are not blindly blind?"

  Ye Feibai now has no time to answer him, his brain is spinning fast, all his strength is concentrated in his fingertips.
