"Key to the Chamber of Secrets (quest item): Might be able to open a secret door."

When everyone saw this key, their speechless mood calmed down a little, and it seemed that it was not for nothing, this key may play a vital role.

"Let's go, move on." Indifference stood up at this time and took the lead in commanding.

"Wait, make a call." When the Iron Bull Demon King was about to leave, he received a text message, and he immediately quit the team channel and called back.

It turned out that the text message was sent by Haikuo Sky, and after he hung up and went back, he was always worried about the situation here.

After the Iron Bull Great Demon King walked to the corner and reported the situation here, he hung up the phone, came to the side of everyone and said, "Da Fei, you will command later." ”

"Why ......" indifferently was about to refute, after all, this was the internal task of the Guild of the Four Seas, and Qi Dafei was just here to help.

"Brother Hai said!" The Iron Bull Great Demon King only used a few words to dispel his indifference, leaving him speechless.

"Don't ......, I'm here to help, it's better for your own people to command this." Qi Dafei had already seen that something was wrong, and hurriedly excused himself.

"Let's go, it's okay!" The Iron Bull Demon King took out a copper coin and threw it on the ground to prepare to open the way, the copper coin thrown before had already been refreshed by the system, and now they can only find a way out again.

"Then let's go, let's discuss it together!" Qi Dafei is also very helpless, after all, this is someone's guild, the boss suddenly hung up and should be commanded by other managers, and now the command is in his hands, this is simply a hot potato, no wonder indifferent will have opinions.

The others didn't speak, the Iron Bull Great Demon King has always been a big grinning character, he doesn't care if you are happy or not, anyway, the sea and the sky have already said, he just has to execute.

The group then continued on their way, but they didn't encounter any monsters along the way, but occasionally found that they turned back again, and as long as they came across a copper coin at the door in the other direction of the room, they picked it up and threw it again, so as not to be refreshed by the system and make their route chaotic.

"This ...... Walked through all four doors? "This is another room, and the Iron Bull Demon King is desperate to find that there is a copper coin at every door.

The indifferent others didn't speak, but they all looked at Qi Dafei, and Qi Dafei had no choice but to take the hot potato and said, "Throw another one, and throw two if you encounter a duplicate one." ”

As soon as they heard this, they felt that this was the only way to do it, so they picked up the copper coins again and threw them again, and the door that was about to choose to enter threw two copper coins at the door.

Qi Dafei looked around as he walked, but every secret room seemed to be exactly the same, and there was no difference at all, let alone a way out.

After everyone turned around, they passed through another door, and found that they were back to the beginning, and above them was the open wall in the study.

"Do you want to go in?" Iron Hammer asked weakly, this task was taken by him, and he was more anxious than others.

"Of course I continued, I finally came to this point, and even Brother Hai hung up." The Iron Bull Great Demon King said without even thinking about it.

"Do you have pen and paper?" Qi Dafei asked casually.

I didn't expect that someone really had this thing with them, and I don't know where they bought it from, Qi Dafei took it from the priest with the paper and pen, unfolded the paper and drew it.

"Tie Niu, let's try again, I'll see if I can draw a map of this place." Qi Dafei simply finished drawing the first room and said.

So under the leadership of the Iron Bull Great Demon King, everyone began to look for a way out for the second time, still in the same direction, and after a while, they returned to the room they had walked in before.

At this time, Qi Dafei had already marked 7 rooms on the paper, and now they are back, but they don't know how many rooms they are back in.

"Let's go back and see how many rooms are there." Although I don't understand why walking in a straight line will suddenly return to the middle, but now there is no other way but to treat him as a normal time, after all, this is a game, some things can be more real, and some things really can't be more true.

They walked back three rooms in a row, and they were back to the beginning.

"If you walk through the seven rooms, you will return to the fourth room, which is the middle one." Fortunately, it is not traceless, at least now Qi Dafei has figured out a little bit of the law of the first route.

"Let's go, let's go!" Qi Dafei said, Tie Niu took the lead and continued to walk, Qi Dafei counted behind, and when he reached the fourth room, he hurriedly shouted to stop.

"Tie Niu, change the room, go to the left 4 times to try it, and throw the copper plate away."

Under Qi Dafei's orders, Tie Niu turned around and began to walk again, as Qi Dafei expected, when they walked through the fourth door, they found that they had returned to the room that had changed direction just now, only this room had two copper plates.

"It's almost clear, this labyrinth has 7 rooms horizontally and vertically, and if you go through the 7th room, you will go back to the room in the middle, which is where we are standing now."

Qi Dafei sorted out his thoughts, drew on the paper, and continued to everyone: "Our entrance is the door in the middle, but the exit is not in the middle, but as long as we walk along the outermost side, we will definitely find the exit." ”

"Just now we have eliminated two exits, one is the door of the seventh room corresponding to the exit, and the other is the room we just walked into, so we have to try 1, 2, 3 ...... now" Qi Dafei counted them in turn on the paper, "There are still 25 exits in the side room that we need to try one by one, I believe that there is always one right." ”

Everyone was dumbfounded, and there were a few people who didn't have good brains and some couldn't react, such as a straight person like the Iron Bull Great Demon King, if you ask him to get these abstract thinking things, he may not be able to understand it for a while.

"You can go as you say, I'm a little confused, I can't react." The Iron Bull Great Demon King simply didn't think about it, and let Qi Dafei have full authority to guide the way.

"In this way, we go to the middle two roads to return to this secret room in the middle, and we don't know if we are back here when we go to the other rooms, you throw a little more copper coins here as a mark, and mark the most central position of this labyrinth where we are now."

With Qi Dafei's guidance, everyone began to experiment according to the map he drew room by room, but this map was still only he could see, so he said that everyone would follow how to go.

Just like what the Iron Bull Great Demon King said, "Although I don't know what you're talking about, I feel like you're right." ”
