Hearing Lu Meng's words, Song Shu could only let her step forward, and at the same time, carefully observe everything around her to avoid accidents.

Although Lu Meng could feel the breath of the Flower God Bracelet, she didn't know if it was her illusion, she always felt that the breath was constantly moving, far and near.

Of course, let's not talk about where the flower bracelet is for now.

How to open the stone door in front of him is a difficult problem.

Without the style or pattern of the key port or combination lock, the ordinary unlocking method will definitely not work.

In addition, since there is a flower god bracelet inside, the doorway that guards the flower god bracelet naturally has a certain amount of energy.

She secretly tried to use spiritual power before Song Shu woke up, but she couldn't open it.

That is, she had to find the right way to open the door.

But there's a catch......

What did Jiang Cheng's gang do last time, how could they be lucky enough to open the door?

Lu Meng looked at the ordinary and simple, without a trace of patterned black stone door and fell into deep thought.

Then, he asked Song Shu: "Have you ever asked Jiang Cheng what they did before opening the door last time?" The more detailed, the better. ”

Before coming, Song Shu would naturally ask this kind of question clearly, and at that time, Jiang Cheng also relayed to him in detail every part he remembered.

Song Shu recalled Jiang Cheng's words and relayed them to Lu Meng: "I heard him say that they were looking for clues separately at that time, Jiang Cheng was in charge of exploring the part of the area on the right side of the stone gate, but in addition to a bunch of small stones and some small grass, there was only a bare wall left, and there was no mechanism pattern on the wall, and when he was about to ask others, the door suddenly opened......"

"Of course, I also went to ask the other brothers in my companionship, and they all said that they couldn't find any useful mechanisms or anything like that, and they saw the door open on its own."

So, from the beginning to the end, they didn't know how the door was opened.

Lu Meng listened carefully to Song Shu's narration, and after hearing the description of some parts of his words, a flash of inspiration suddenly flashed in her mind.

There was a sudden movement under his feet, and he walked towards the area on the right side of the stone gate before Jiang Cheng said in Song Shu's words.

After a little fumbling, I turned on the flashlight, and sure enough, in a certain corner, I found a pile of weeds and some inconspicuous pebbles.

When I stepped forward and carefully touched the surface of the weeds, the roots of the grass were a little yellow, but the pointed parts of the grass were green and green.

The normal appearance should be the other way around.

At this time, Lu Meng turned to stare at Song Shu, "Have you asked about the direction explored by several other people?" ”

Song Shu was stunned, Miss Lu looked like this...... Did you find something?

However, he quickly replied to Lu Meng's question, "They explored in four corners, and they couldn't tell the direction here, with the stone gate as the basic direction, which were the left and right sides of the stone gate, or the left and right front of the stone gate." ”

Lu Meng went to survey the four locations according to the Song book.

A confident smile tugged at the corners of her lips when she saw something.

She finally knew what the problem was.

And she also knew why Jiang Cheng accidentally opened the door before, but after the door opened, he would be attacked immediately.

Because...... They didn't really open the door in the first place, and accidentally activated the mechanism set up by the door.

That's why it's attacked.

Song Shu saw the expression on Lu Meng's face and guessed that she knew how to open the door.

Although surprised, on Lu Meng, it seems to be ...... And take it for granted?
