The Chosen System: Counterattack with Husband

The gas mask blocked the corners of Rong Yan's mouth, which were a little uncontrollable at the moment, and even Lin Yi, who was accustomed to keeping a blank expression, turned his gaze away slightly.

Fortunately, they already knew that their tour leader was a person who would occasionally get addicted to acting, so they didn't burst out laughing.

In such a serious atmosphere, she can still act like a movie queen. I'm afraid she has already maxed out her skill of finding joy in adversity.

"Please, give us, ahem, a road to heaven, a sample."

Lin Yi stretched out his arm and pointed to the high stairs behind Xu Yiyu, pretending to be serious and acting with her.

Well, it’s not difficult for him to hold back his laughter, really.

Rong Yan nodded in agreement and subconsciously raised his hand. He wanted to press the corners of his mouth manually, but the gas mask on his face blocked his way.

"No problem. Please wait for Xu to go up and explore the way."

Xu Yiyu raised his head and deliberately patted his chest vigorously, putting on a reliable look that said, "Just wait and see."

But when she turned around and looked up the spiral staircase, she instantly returned to her original calm and peaceful expression.

Although Xu was deliberately joking just now, she really wanted to explore the way ahead of her companions.

The next moment, Lin Yi and Rong Yan saw with their own eyes Xu Yiyu who had been deliberately amusing them just a moment ago——

It disappeared from their sight at a speed that was almost invisible.

After more than ten seconds, Rong Yan manually closed his jaw which was open in surprise, and glanced at Lin Yi's face.

The eyes beneath the gas mask were still focused and resolute, without even a hint of surprise.

He is indeed worthy of being the captain of a provincial criminal police corps, able to remain unmoved even when faced with a mountain collapse.

Rong Yan turned his gaze back to the dim spiral staircase in front of him and vaguely heard footsteps that seemed to come from above his head.

Well, Sister Yi Yu is a non-staff member of the atmosphere group who understands contrasts. That’s confirmed.

On the other side, Xu Yiyu, who had already run out, used his eyesight to look all the way, but did not find any clues on the side walls on both sides that could trigger the mechanism.

As the spiral staircase gradually rose in height, the torches on the side walls gradually lit up, as if recognizing the presence of the visitor Xu Yiyu, and the cold flames gradually illuminated the road ahead of her.

Although Xu Yiyu climbed the stairs quickly, he did not forget to pay attention to whether there were any triggered traps under his feet.

But along the way, every step she took was solid, and not a single step was missed.

Not right.

Twelve out of ten things are wrong.

Soon, as the last flame was ignited, Xu Yiyu also climbed to the highest point of this spiral staircase.

When he saw clearly the "door" in front of him that was not really a door, no matter how good Xu Yiyu's mentality was, he almost couldn't help but swear in his heart.

Okay, okay, all the calmness along the way was just to pave the way for this moment, right? She, Xu, is impressed!

After taking a quick look at all the details of the "door", Xu Yiyu took out his mobile phone, which had no signal long ago, from his coat pocket with an expressionless face and took a few photos of the "door".

If being speechless is also a kind of danger, then her current situation is definitely extremely dangerous.

After taking the photo, Xu Yiyu turned around and walked downstairs without any reluctance, not wanting to look at this "door" again.

She was certain that the owner of the underground palace must have some evil taste in teasing new comers.

Before Xu Yiyu came up, the black cat that had just been lying on her shoulder had already jumped off her shoulder and was now squatting at the feet of Lin Yi and Rong Yan, as if it was not worried at all that Xu Yiyu, who was out exploring the way, would never come back.

But at this moment, Xu Yiyu just wanted to rub the black cat's cute face a few times to avenge the black cat for teasing him.

What could be wrong with Mimi?

Mimi just wanted to see the Twolegs’ expressions break down.

But a few minutes later, Xu Yiyu returned to Lin Yi and Rong Yan just like when he went to explore the way.

Without waiting for her two companions to ask about the situation ahead, she took out her cell phone from her coat pocket with a helpless look on her face and placed it in front of them.

Rong Yan looked at the photo carefully, then glanced at Xu Yiyu who had a "violent" look on his face, and almost couldn't help laughing.

Lin Yi just widened his eyes slightly and then cast his gaze towards Xu Yiyu who seemed a little angry.

"First of all, I would like to state that I am not good at mathematics, not that I have any prejudice against this mechanism or its designer."

When Xu Yiyu said this in what she thought was a relatively calm manner, Lin Yi and Rong Yan both heard the gnashing of teeth hidden in her tone.

Rong Yan believed that if the designer of this mechanism stood in front of Xu Yiyu now, his sister Yiyu would rush up to duel with him without hesitation.

"Sister Yi Yu, let me take a closer look at the photo. Although I'm not an orthodox science student, my math... is pretty good."

I don’t know if it was Rong Yan’s illusion, but after he said this, he seemed to see that Sister Yi Yu’s resentment became a little heavier.

After handing the phone to Rong Yan, Xu Yiyu immediately squatted down, picked up the black cat that was sitting elegantly at the feet of his two companions, and rubbed its face frantically with both hands.

The black cat seemed to have anticipated Xu Yiyu's reaction. It neither hid nor cried out, but just let herself be "ravaged" by her obediently.

"Come on, let me see what's going on."

Rong Yan half-knelt down holding his phone, and took out a pen and mini notebook from his pocket with familiarity.

It also made Xu Yiyu's words about "Ice and Fire" come true again.

Xu Yiyu's hands, which were rubbing the black cat, paused for a moment and his eyes drifted towards Rong Yan.

Although she was smiling, the look in her eyes was somewhat complicated.

——A 15 times 15 Sudoku matrix is ​​enough to give her a headache, as she is a student with severe academic imbalance who gets a headache when she sees slightly complicated math problems.

If she could deduce the answer to the 3x3 nine-square grid according to the formula "two and four are shoulders, six and eight are feet", then this obviously much more complicated Sudoku was obviously not within her area of ​​expertise.

What kind of good person would find time to do math problems while exploring an underground palace?

Come, the owner of the palace whose true identity is still unknown, come out and tell us about your mental journey when you set up this mechanism.

Did she just want to see the expression on the face of a latecomer like her, Xu, who was not good at math?

The owner of the underground palace’s thoughts are really... too abstract.

She, Xu, is tired of guessing and doesn't want to guess anymore.

Rong Yan carefully examined the layout of the Sudoku matrix and the known numbers in the photo, and with his other hand he took a pen and began to write and draw on the notebook.

Lin Yi stood aside with his arms folded, not interfering with the actions of the two squatting people, but just waiting quietly for Rong Yan to give an answer.

Two minutes later, Rong Yan did not give the answer to the Sudoku, but made a somewhat unexpected move.

He closed the notebook in his hand with a "snap", pointed to the top of the spiral staircase with his pen, looked at Xu Yiyu with a smile and spoke.

"Sister Yi Yu, the photo is still too blurry, how about we go up and see the real thing?"

Lin Yi swore that he definitely saw the almost invisible twitch of Xu Yiyu's mouth in one thousandth of a second.

However, this expression flashed by very quickly, and the next second, a smile appeared on her face again.

"Okay, let's go up together... and see the real thing."
