Beautiful girl, do we still have anything unsolved? Why is there no mechanism here?" The white fox walked around the door in confusion, with a puzzled face.

Since there is a door, it must have a way to open it, otherwise the design of this corridor will lose its meaning.

Zhi Yao was also puzzled, she had never encountered this kind of door without a switch, or that the switch had been destroyed in the fight?

Zhi Yao thought about it seriously, and thought about the recent things on this road, and suddenly a flash of inspiration came to mind.

Zhi Yao carefully took out the flint from the storage ring, and the flint was wrapped in the sheet, and Zhi Yao could only hold it through the sheet.

"Lao Bai, get out of the way, I'll try this is feasible. Zhi Yao said to the white fox.

As soon as the white fox saw the flint, he remembered the experience of being burned, and immediately jumped far away, looking at Zhi Yao curiously.

Zhi Yao settled her mind and tentatively printed the side of the flint towards the gate.

Suddenly, the gate melted with a sneer, but in a moment's time, it was completely melted away, spreading out in all directions.

A solid gate was completely burned down and reduced to ashes in just a few breaths.

Zhi Yao hurriedly put away the flint stone and continued, she was afraid that this road would be ruined.

However, the power of this flint stone is too great, which is really beyond her expectations.

It's a pity that this thing can't be recognized, and it can't be touched at will, so it's a bit weird to hold it with a sheet.

The white fox shuddered as it watched the gate melt quickly, and suddenly felt that it was lucky that it was not burned to death.

"Let's go. Zhi Yao beckoned to the white fox and walked out cautiously.

The white fox followed Zhi Yao closely and followed carefully.

As soon as she stepped out of the door, Zhi Yao found herself in a large hall again, which was currently empty, and she should be the first to come out.

And there were twenty more doors in this hall, and each door had a key groove on it.

Zhi Yao thought of the three keys she had gotten almost immediately, and immediately took them out of the storage ring.

After carefully observing the three keys, Zhi Yao found that a pattern suddenly appeared on them.

One has a lightning bolt pattern on it, which should be a thunder attribute.

One has a stone on top of it, which should be an earth attribute.

The other is a flower, which should be of wood attribute.

Zhi Yao turned to look at the doors on both sides that had not yet been opened, and she was a little anxious in her heart, presumably it wouldn't be long before the others would have to pass through the Yongdao, so it was better for her to go in early.

Thinking like this, Zhi Yao took off the hat, she was so arrogant before, if she was recognized by them, she was afraid that she would be beaten by the group, and finally die a desolate death.

It's better to be so generous, and if you meet them, you can explain that you are from somewhere else.

No matter what, it's better than wearing a hat.

Zhi Yao walked in front of several doors in turn and began to look for the corresponding door, and soon, she found the door corresponding to the flower.

But Zhi Yao didn't choose to enter, for her, choosing the thunder attribute must be the most helpful.

If you enter a door by yourself, you will inevitably meet other people when you come out, and you will probably miss the door behind you.

Therefore, it is most reasonable to choose the Thunder attribute.

After a while, Zhiyao finally found the door, and she gently printed the key.
