However, they still have to solve this problem and do these things well, otherwise they will have no way out.

Xu Haojie, Zhao Xincheng and the other three must suppress the feeling of fatigue in their hearts and continue to solve this problem.

Now Fang Hui said to the three of them: "We should think about how to solve the mystery of this switch, since it was painted on it.

It is proved that there must be other solutions, and now that we have found the switch that opens the exit, the next thing we have to do is to combine the two and get out of this secret passage.”

Zhao Xincheng and Xu Haojie were also cheering each other up because they felt that they were about to go out and now they had reached the most critical and final step.

After solving this matter, they can go out of the secret room smoothly and meet with Ye Wuque. They may be able to start the third level of mission.

"Do you think this pattern is implying that we should actually find an actual key to open the exit."

After Xu Haojie said that Zhao Xincheng, Fang Hui, and the little boy were all in deep thought, and felt that what Xu Haojie said was indeed a little reasonable.

But the surroundings of this secret room are empty and there is nothing at all. How can I find a key that can open the exit?

They really felt that this was really difficult, and they looked up at the exit of the wall above their heads, and there seemed to be no place to insert the key into next to them.

They also looked at Xu Haojie in confusion. Xu Haojie naturally thought of this, so he continued: "Although we did not see the keyhole next to the exit, we have no way to find the key now.

But it does not mean that these things do not exist. Think about it, it is not a very strange and very strange thing that we will come to this secret room."

After Xu Haojie's reminder, it was indeed a matter of explanation that they would come to this secret room that could not be solved by science.

Now they still look at these things with a very scientific perspective, and there is definitely no way to solve them. Now they have abandoned the idea of ​​looking at these things with a scientific perspective.

But from some other aspects, perhaps as Xu Haojie said, it is the key to existence. But they cannot observe or see with their naked eyes.

If they solved this problem from another perspective, they might be able to find it, so now that Fang Hui heard Xu Haojie say this, a light of inspiration flashed in his mind.

But he couldn't catch it if he wanted to catch it. He said in a vague manner: "You guys say we can't see it with our naked eyes, but we can still touch it with our hands?"

After Fang Hui said it, the more he thought about it, the more he felt that what he said was indeed quite reasonable. After all, they would appear in this secret room, so there was no way to explain it with a scientific perspective.

So now they can think from other aspects, maybe they can't see it with their naked eyes, but touching it with their hands may be achieved by touching it.^

Fang Hui thought this way and decided to actually practice it, so he said to Xu Haojie and Zhao Xincheng now: "That's it, Zhao Xincheng, Xu Haojie, you two are forming a wall of people, I'll climb up.

Let’s see if there are any protruding places around the exit and whether there is a hole to insert the key. If so, we will follow the idea that Xu Haojie said to find the key.”

Xu Haojie and Zhao Xincheng could also understand Fang Hui doing these things. They thought this was indeed too strange, and this was the only way.

So the two of them nodded and then built a human wall. Fang Hui did not waste time and climbed up directly. He was searching there at the exit of the wall above his head.

He used his hands to feel whether there was a raised key hole on the wall. Fang Wei touched it and felt that the wall was very smooth, there was no key hole at all, and there was no raised area at all.

Now Fang Hui really felt something was wrong with his thinking, but he did not give up. He kept touching the side with his hands, and he kept expanding the scope.

He thought that since the wall under their feet was painted the shape of a key, it proved that this place must be opened with a key.

Now Fang Hui continued to search here, and Xu Haojie and Zhao Xincheng were both a little unable to hold on. After all, they had been in this underground palace for a while, and now they were a little lacking in physical strength.

Xu Haojie and Zhao Xincheng were urging Fang Hui there, and Xu Haojie said to Zhao Xincheng: "How about it, Fang Hui, have you found the keyhole?"

Fang Hui knew that Xu Haojie and Zhao Xincheng would be about to be unable to hold on, so he also accelerated his touching speed. He was sweating profusely and was very nervous.

I wanted to find it quickly, but I couldn't find it quickly.

The little boy said from the side: "Brother Fang Hui, don't worry, you can't find it once, we can search twice or three times."

As soon as the little boy finished speaking, Fang Hui suddenly felt a place with a raised feeling. Fang Hui looked at that place in surprise.

Although it was still very smooth when he looked at it, even when he touched the raised area, it was a little smoother than other walls.

But he did touch the place with the keyhole, so Fang Hui shouted now: "I touched it. There is indeed a raised place here. Do you want to come up and touch it?"

Xu Haojie, Zhao Xincheng and the little boy heard Fang Hui say that he had touched the protruding place and the keyhole.

All three of them were quite excited because they did not do this wrong and finally did not think about it wrong. Fortunately, they found this solution.

Although Xu Haojie and Zhao Xincheng and the others are now building a human wall and letting Fang Hui climb up to check it out, they are indeed a bit tired, but they think these are worth it.

After all, Fang Hui has found the place to insert the keyhole. After Fang Hui came down from above, Zhao Xincheng, Xu Haojie and others have been talking about this.

Zhao Xincheng and Xu Haojie were also very excited. They also wanted to see it, but they knew that if they went up and touched it, they would definitely waste more energy and physical energy.

They still think it's good to keep these energy and physical strength, and they shouldn't waste it on these loves and places. Anyway, since Fang Hui touched it, she must be touched there and would definitely not deceive them.

"Since we have now confirmed that we need a key to open the exit, but where are we going to find a key now."

After Zhao Xincheng asked this, Fang Hui and Xu Haojie were all in deep thought. They really didn't know where to find the key to the key now.

I don’t know if I should start from it, after all, it’s really empty in this secret room, nothing, nothing. They want to find a key in this empty room, isn’t that just making a difference?

Moreover, they had knocked on the surrounding walls before, and they had not found any gaps at all, and it was impossible for them to have any dark grids or other things.

All of them were in deep thought. Suddenly, Fang Hui had a light of inspiration and felt that although they had already confirmed that the surrounding walls were solid, there was no secret place at all.

But they also ignored two places, one was the wall above their heads, and the other was the wall they stepped on under their feet.

It would be really bad if they ignored these two places and passed by the final answer just like before.

So now Fang Hui immediately expressed his thoughts. Fang Hui said to Xu Haojie and Zhao Xincheng and the little boy, and he felt that the key must be on the wall above his head.

Or they should look for the wall they stepped on under their feet, just like they just looked for the surrounding walls and knocked on whether the surrounding walls were hollow.

But they didn't think about checking the piece above their heads and stepping on the piece under their feet. Now after hearing Fang Hui's explanation, they felt that Fang Hui was really considerate.

They didn't think of this at all, and the little boy felt that the key was probably on his head, because the painting on the wall they stepped on under him was definitely useful.

Otherwise, why would the owner of the underground palace do such a thing? Draw a key shape on the wall below, which is simply a thing.

So now the little boy also expressed his thoughts and said to the three of them: "I think this key is very likely to be on the wall above our heads. Why don't we focus on the wall above us?"

When Zhao Xincheng and Fang Hui heard the little boy say this, they also felt that the key might be hidden on a wall above their heads.

But now there is a question of how they should look for it. If it is in the bottom, four people can act separately, but in the wall above their heads, they must make a wall.

That would consume a lot of energy and physical strength. If they couldn't find it all at once, they would spend all their energy and energy. What should they do?

Now Xu Haojie also raised his question. Xu Haojie was very confused. This matter was indeed a bit difficult to deal with.

"But you don't think it's a bit troublesome to really find the wall above our heads, because you also know that just now, I was very tired when Zhao Xincheng and I reached the wall.
