The system asked me, a weak woman, to challenge a saint

Zhu Laosi sent someone back to the camp in the early morning of the next day to pass a message, saying that he had gone up the mountain from the mountain road on the west side of the valley, and indeed found a camp near the top of the mountain. After Zhu Laosi and others expanded the search on the spot to confirm that it was safe, they sent a message the next morning. A guard came back to deliver the message.

Zhou Wanshan and Xiao Yuhan did not delay and quickly led people to the Xishan camp.

The Xishan Camp is not at the highest point of the west mountain range, but in an open area under the main peak. It is a long-term camp with complete living and production facilities and can accommodate no less than 100 people for mining, grinding, and storage of ore.

In a mine tunnel in the camp, Zhou Wanshan, Zhu Laosi and Xiao Yuhan stood in front of the closed stone door.

Zhu Laosi said: "We explored this mine last night. All other routes in the mine have been found to be dead ends for mining. We forced open other rooms and secret rooms that cannot be entered directly. Only two doors cannot be opened. . I have just seen the door below, and there is no trace of any mechanism at all, but there is something different about this door."

While introducing the situation, Zhu Laosi used a torch to illuminate the two grooves on the left and right of the stone door, as well as the twelve zodiac signs arranged on the left and right sides of the door.

"Hmm... it looks like a machine lock. We currently have too few clues. We still need to explore a little to see if there are any items in the camp that can be placed in this groove." Xiao Yuhan frowned and looked at the stone door. In her previous life, she particularly hated doing Mathematical Olympiad questions and guessing riddles. Now, as the only educated person, it is simply a kind of torture for her to decipher the mechanism.

"Chen Subaru didn't have time to think about the Five Elements Bagua, and now I'm here as a tool." Xiao Yuhan muttered to herself when she saw Zhou Wanshan and Zhu Laosi leading people to search. In fact, deep down in her heart, she also wanted to see what good things there were in this secret realm. As long as she was not risking her life, she didn't care if she occasionally used her brain. Moreover, she was right this time, watching those people look at her with admiration. The look in her eyes still showed a sense of accomplishment, and even at this moment, there was a smile hanging on the corner of her mouth that she was not aware of.

Two hours later, Zhou Wanshan and Zhu Laosi came to the stone door with two jade tokens and smiled. Xiao Yuhan was knocking at the door trying to find out the layout.

"Brother Chen, can you see if you can use these two jade tokens to unlock the trap?" Zhu Laosi walked quickly and handed the jade token to Xiao Yuhan. Xiao Yuhan took a jade token and placed it in the groove on the door, making it a perfect fit. . The jade tablet emitted a yellow-green light, and at the same time, the entire stone gate also emitted a faint yellow-green light, which flashed away.

Xiao Yuhan signaled Zhu Laosi to install another jade sign, and the door flashed again and then fell silent. Xiao Yuhan was confused. She thought there would be at least a reminder or something, but this is what happened?

"Xiaoxuan, what's going on?" Xiao Yuhan decisively gave up thinking and asked the system directly for help.

"Xiao Hanhan, do you really expect two pieces of jade to drive the entire gate? The energy is not enough~"

"Not enough energy? How to conduct energy?" Xiao Yuhan has become accustomed to Xiao Xuan's ridicule. He doesn't hesitate and asks directly if he doesn't understand.

Xiao Xuan did not answer her question, and Xiao Yuhan had no choice but to solve it by herself. She observed the distance between the two grooves, and her left and right arms could reach each other at the same time, so she pressed her two hands on the jade tablet and injected spiritual energy into it. Power, the jade card immediately glowed with yellow-green light. Xiao Yuhan thought it was feasible, so she increased the input of spiritual power. The jade tablet began to radiate waves of light outwards. The two wave sources continuously released the light wheels. The two waves intersected to form a straight line, connecting 11 holes with the diameter of the door gap. point, 3 o'clock, 7 o'clock direction.

With the continuous injection of spiritual power, the light of the entire door became stronger and stronger, and the two jade tablets turned bright yellow. Until the twelve zodiac signs lit up, the stone door made a clanging sound, followed by a clicking sound. sound.

While everyone was excitedly waiting for the Shimen to open, the Shimen became quiet.

When Xiao Yuhan felt that the spiritual power absorbed by the Shimen was saturated and could no longer be injected, her hands left the jade tablet. The light of the Shimen showed no signs of disappearing or weakening. She took a few steps back and looked at the motionless stone door, observing the triangular light of the stone door, then looking at the twelve zodiac signs, and fell into deep thought.

"The two stone gates look square together, so what does it mean to draw a triangle like this? What does this have to do with the twelve zodiac animals?" Xiao Yuhan was already a little irritable when facing one puzzle after another. She hates solving puzzles.

Zhou Wanshan looked at Xiao Yuhan, who was frowning, and then looked at Shimen, and said in a deep voice: "Brother Chen, is this mechanism also a coincidence hexagram?"

"The position of this connection does not conform to the arrangement of the Yin and Yang Bagua..." Xiao Yuhan answered without thinking and then suddenly froze. She suddenly thought that if there was a compass, in addition to considering the Yin and Yang Bagua, she would also have to consider the Yin and Yang, the Five Elements and the Heavenly Stems and Earthly Branches. The twelve zodiac signs correspond to the twelve earthly branches, so the connecting position should be the arrangement of the earthly branches turning a circle into a square.

"11 o'clock is the Si position, 3 o'clock is the Unitary position, and 7 o'clock is the Chou position. This is the three-alloy game!" Xiao Yuhan exclaimed softly, and then she tapped the three patterns of snake, chicken, and cow with her hand. In the surprised eyes of everyone, the three patterns flashed with light, and then the entire stone gate became silent and dim.

Xiao Yuhan's eyes widened, unable to believe all this, and a thought immediately appeared in her mind: "Did I guess wrong?"

"No, Xiao Hanhan, you guessed it right. It's just that if you use the power of the Five Elements to break the formation, the result must fall on the Five Elements. You don't borrow the Five Elements from the Three Combinations~." Xiao Xuan's voice sounded, pointing out Xiao Yuhan's omission.

Xiao Yuhan had no choice but to use up her spiritual power to reactivate the stone gate. When the brilliance of the twelve zodiac signs on the stone gate lit up, she chose to slap the monkey and the rooster. This time, the brilliance of the stone gate flashed and slowly opened.
