It is impossible to explain, at least not yet.

So when the three of them didn't know the answer they wanted from Qi Zhen and Li Qiang, they didn't have too disappointed expressions.

After all, in the game, Li Qiang and Qi Zhen's considerations are only much deeper than the three of them.

It's just that I'm still a little curious.

Then a few people walked through the main hall and came to the illusion enchantment that Yu Yao had arranged.

The magic of the so-called illusion enchantment lies in the fact that even if you walk in front of it, as long as you don't step directly over the boundary with one foot, there will be no incongruity in the feedback of the vision, just like the real thing.

So when the scene in front of everyone's eyes suddenly changed from the red walls and green tiles in the inner courtyard of the deep palace to a pitch-black mountain stone and rock wall, even if they were mentally prepared, they were still shocked by Princess Yuyao's methods.

Stripped of illusion, the scenery here really feels like an underground mound.

Of course, the walls and mountains here still do a lot of support to avoid any external force that could cause something like a landslide.

The black stone walls also have some obvious traces of artificial modification.

Finally, there is more quiet and solemn meaning, less of those fireworks in the world, and less of those inexplicable magnificence, carved beams and paintings.

The crowd began to scatter around looking for clues around them, to see if there was a way to get to other places, or some clues that could lead to the rest of the story.

Except, of course, Xiao Ao.

The others were also accustomed to this matter, and when they saw the white-clothed figure behind the negative hand, they were all speechless.

Facts proved that Qi Zhen's guess was not wrong, and after looking around, Meng Ran took the lead in finding an unusual place in front of the mountain recess on one side.

A boxy organ.

This recess is really neatly made, as if a piece of the mountain here was deliberately pulled out, forming a space in front of it that looks like nearly 100 square meters.

The location of the mechanism was in the middle of the wall in the middle of the mountain recess in front of the team.

When he heard Meng Ran call the others to his side in an unbelievable tone, and when he saw the boxy mechanism in front of him, even if he was as calm as Li Qiang, he couldn't help but have a trace of astonishment on his face.

Mainly because this mechanism is so familiar to everyone.

In the previous life, this mechanism had a very magical name, called Huarong Dao.

Huarong Dao is the road taken by Cao Cao's defeat during the Three Kingdoms period, I don't know if it was inspired by this story, and later generations created this puzzle game.

Of course, there are no Three Kingdoms in this world, and naturally there is no Cao Cao, so on those large or small squares, the numbers marked are only uppercase and traditional characters.

But the meaning is pretty much the same.

Huarong Road has a chessboard with 20 small squares, and the player needs to move each piece to help the largest piece above move from the initial position to the bottom of the whole trap and escape through the exit. It is not allowed to leap the pieces, and at the same time, try to move the largest piece to the exit with the fewest moves.

In the game in his previous life, the biggest obstacle for Cao Cao to escape from Huarong Dao was Guan Yu, Guan Yu immediately Huarong Dao, one husband should be a pass, and ten thousand people should not be opened.

Therefore, the chess piece that occupies two squares in the middle is usually written with the word Guan Yu written on it, and how to solve it has become the key to how to unlock this mechanism.

And here, the word written on this chess piece is a 捌.

And on the biggest chess piece representing Cao Cao, it is written that it is picked.

There are only ten boxes of different sizes, occupying twenty fixed grids of the whole mechanism, of which the two empty spaces are the space that can be moved.

It's a fun puzzle game that isn't too difficult, and with enough time, everyone in the squad should be able to solve the trap.

"I'll come, I'll come, I'll do this!"

Yu Liang stepped forward with a big grin, and directly moved the smallest block in the mechanism in front of him with three written on it a block downward.

As Yu Liang moved the inconspicuous little square in front of him, the ground under the team's feet began to tremble.

After a burst of reeds, a rumbling sound echoed through the space.

Frightened, Yu Liang quickly stopped his hand that was about to continue moving.

"What's going on?" Yu Liang hurriedly asked.

Qi Zhen showed a hint of surprise on her face when she heard these voices, and said softly, "We probably met the real thing." ”

If it encounters the real one, it naturally does not mean that the team has encountered the real Huarong Dao, and they will have another battle with Liu Bei's army.

But what Qi Zhen said, except for Xiao Ao, everyone else instantly understood what Qi Zhen meant.

I don't know how the boxy chessboard in front of me is connected to the mountain here, or if it was built deliberately as part of the mechanism.

The current team is afraid that they are only in the pick-up area, and once they adjust the position of these small squares in front of them, the mountains in this place will also move.

Until the squad walks out.

This is much more advanced than the ordinary Huarong Dao game.

After listening to Qi Zhen's explanation, everyone gradually relaxed a little, for fear that Yu Liang, who had just caused some big disaster, also breathed a sigh of relief at this moment.

Thankfully, there won't be any unpredictable danger to the team.

Just when Yu Liang hadn't finished his breath, there was a sudden click next to the Huarong Dao chessboard in front of him, revealing three engraved numbers.

Nine picks.

Then the last word turned up, and it became a 捌.

Below these three words, three engraved numbers also clicked, on which were written "捌拾壹", and then it became a "捌拾", and then it stopped moving.

Fools also understand what this means.

Before the ninety-nine countdown is completed, the team must complete the game within eighty-one steps, otherwise the outcome is unknown.

"Damn!" Yu Liang shouted.

Naturally, no one wants to try what happens after counting down to zero-zero-zero.

So Qi Zhen should have said "I'll come" at this time.

No one robbed him.

As the chess pieces in front of them continued to move, the rumbling sound began to echo in everyone's ears.

At the same time, a dense layer of sweat gradually appeared on Qi Zhen's head.

When Qi Zhen moved the square with the pick-up on it, the wall in front of the crowd also moved.

The team had to move along.

Qi Zhen seems to be relaxed and freehand, but in fact, there is no one to say about the tension in her heart.

He just didn't want to make his teammates anxious.

Needless to say, whether it was Li Qiang or the other three, none of them had Qi Zhen's deeper understanding of this game.

Qi Zhen's understanding of games, to be precise, of these puzzle games, is far higher than his attainment in playing large games.

And for the game in front of him called Huarong Dao, Qi Zhen is just one of the games with a very deep understanding.

After many years of research by senior gamers, there is a 100-step solution in China, and then it has been reduced to 82 steps after continuous exploration, and finally it has been reduced to 81 steps by relying on the deduction of modern scientific computers.

In other words, the Huarong Dao that the team is facing today is the most complicated state of this game.

No one knew the anguish and shock in Qi Zhen's heart when she saw the number eighty-one.

Just like now, no one can appreciate Qi Zhen's caution when moving the chess pieces.

Others only know that they are worried that the number of ninety-nine from the bottom above will decrease little by little, but it is difficult to understand that the number eighty-one is the most fatal for everyone now.

The first of the three engraved numbers above changed from Jiu to 捌, and then to Qi.

However, the position behind the team had just been tightly blocked by the mountains representing Lu and Er, respectively.

Qi Zhen stopped the movement in his hand at this time.

"Why did you stop?" Yu Liang asked.

Qi Zhen wiped the sweat from her forehead with her sleeve, and her eyes were fixed on the chessboard in front of her.

The three words representing the number of steps have become Wu Shijiu at this time.

"I want to think about it." Qi Zhen said lightly.

Qi Zhen closed his eyes uncharacteristically at this time, and began to deduce silently in his heart, the appearance of the chess pieces on the chessboard in front of him had been deeply engraved in his heart.

You can definitely do it, and you must have no problem figuring it out with your own mental strength!

The chess pieces kept changing positions on the virtual chessboard in their minds, and gradually became clear.

Pregnant! Qi Zhen's eyes lit up suddenly!

Eighty-one steps, one step is not much, one step is not less!

"Is it hard?" Yu Liang asked suddenly.

Qi Zhen nodded, and then looked shocked!

It turned out that Xiao Ao came to the chessboard at some point, and moved back the square with the word "two" that Qi Zhen had just moved.

Then he looked behind him, and as he moved, the mountain behind him rumbled and began to move, revealing the space behind him.

Qi Zhen looked at the engraved number that had become Wu Shi, and her face turned pale.

"Look at the back." Xiao Ao said suddenly at this time.

When they heard this, they looked back, where they had just stood.

Xiao Ao's body is a stalk, and his vision at night is naturally very keen, and he saw a palm-sized pattern in an inconspicuous place on the ground.

If it weren't for Xiao Ao's reminder, everyone would not have been able to find out about this.

It was a mark that looked like a flame,

Yu Liang nodded: "It seems that there are really some other unusual things in this underground, can you see anything?" ”

Xiao Ao thought about it, but shook his head.

Qi Zhen didn't look back at all, he just closed his eyes again.

After Xiao Ao moved this step, the puzzle that could be solved by eighty-one steps was instantly reduced to seventy-nine steps, which was equivalent to wasting two steps between this back and forth.

The countdown is no longer enough at this time......

Wantonly picking, wantonly picking......
