Wang Xiaowan did leave a shadow on his mistake last time, and this time he was too cautious to be a bit of a soldier.

Luo Xiaobei knew that Wang Xiaowan was a sequelae, but he didn't break it down. But the smile on the corner of his mouth couldn't be concealed no matter what, and he took two steps closer to the lake, thinking if he could get a closer look at the reason why the lake glows at night.

The glittering mangs bloomed on the surface of the lake, and then slowly swung to the sides. Circle after circle, layer after layer, like starlight piled up in one place.

"The lake glows at night, is that why the water has a color?" Wang Xiaowan followed behind and looked at the bottom of the lake.

However, the dazzling waves on the water surface are about to sparkle people's eyes, and even if you look down, you really can't find anything.

"Probably not!" Luo Xiaobei thought that when they followed the Han family's sister-in-law to the location of the mausoleum, when they stood in the place where they could see the strangely colored water coming out in the daytime, they didn't see such an incredible picture in front of them.

In other words, the scene in front of you may have nothing to do with the color of the water, but something else under the lake.

Luo Xiaobei glanced back at Wang Xiaowan, who was staring at the lake thoughtfully, and said, "Sister Xiaowan, what do you think?" ”

Different from the previous banter, the expression on Luo Xiaobei's face is very serious now.

Wang Xiaowan nodded, "I think the same as you!" ”

The two reached a consensus, and without further ado, they glanced at each other and jumped into the water together.

Unlike the cloudiness in the daytime, the underwater vision at night is surprisingly clear, which is even more puzzling.

The temperature under the water seemed to be colder at night, but it was clear and transparent as far as the eye could see, which made the two feel a lot more relaxed.

According to what had been discussed during the day, the two of them no longer devoted themselves to diving, but tried to focus their exploration on the stone walls around the lake. Because the line of sight is clear, the pace of the two is the same.

It was only after getting close to the stone wall that the two discovered the reason why the water in the lake glowed at night.

In fact, it's not the water that glows, but the deliberately hewn stone wall filled with water.

The stone wall looks like an ordinary stone during the day, but at night it glows white. This white light has a strong penetrating power, and when combined with the lake water, it turns into blue light.

And this light seems to have the effect of automatically purifying water.

This is a new discovery. If it weren't for the fact that it was important to find a mechanism now, Wang Xiaowan really wanted to chisel a piece of this stone wall and take it back to study and study.

Such convenient conditions and strange phenomena made the joy in the hearts of the two of them even more. After a short ventilation, he continued to devote himself to the journey of finding the mechanism.

Luo Xiaobei's hands were about to be frozen, as if they had been soaked in water for a long time, and she even felt a faint warmth coming from her body. The movements of his hands quickened, and he kept groping for the stone wall.

The stone walls here seem to have been excavated in situ, and no excess processing materials have been used. So much so that Luo Xiaobei and the others explored all the way, but they didn't touch the trigger device that might be related to the mechanism or the secret passage.

The whole process changed three times, and the original interest and interest were consumed less and less in each failure. The physical strength of the two is almost unable to keep up, and if they don't give up, they will be buried in the dark river.

Luo Xiaobei had too much helplessness in her heart, was her judgment wrong at the beginning? Does this lake have nothing to do with the entrance to the mausoleum?

The frustration in his heart grew, and just when Luo Xiaobei decided to give up and kept gesturing to tell Wang Xiaowan to go up again, Wang Xiaowan waved his hand eagerly to Luo Xiaobei.

Does this mean a discovery?

Luo Xiaobei was overjoyed and walked in the direction of Wang Xiaowan, but Wang Xiaowan's waving movement became more and more urgent, faster and faster, Luo Xiaobei didn't understand what she meant, and was about to stop, when a warm current suddenly rushed from behind him.

Under the action of the huge buoyancy of the water, Luo Xiaobei's already light body was pushed by this warm current and quickly crashed into the place where Wang Xiaowan was.

The short, non-painful touch shocked both of them, and as soon as they opened their mouths, water filled their ears and noses. The feeling of suffocation quickly pressed from all directions, and the two of them struggled for a short time before being sucked in by a huge whirlpool.

Luo Xiaobei was frightened and frightened, and the moment the darkness hit, what she thought in her head was, "Oh no! Another accident happened! ”

These unplanned things are all Luo Xiaobei's so-called accidents.

The so-called accident is the warm current, and she and Wang Xiaowan will drown because of this warm current.

Luo Xiaobei never expected that such a closed and not big lake, in addition to the strangely colored river water from the underground dark river, there was another entrance to the water flow that was not easy to detect.

The water of this warm current is not hot, but relatively from the underground dark river, and this water brings warmth to Luo Xiaobei.

Luo Xiaobei only realized before he lost consciousness that the stone wall, which seemed to have no gaps, should have gathered many culverts. When the outlet of one culvert is opened, the water in the other culvert is closed. Or that there is a time lag between the opening of the two culverts, which causes warm currents to rush in first, and then whirlpools.

Perhaps Wang Xiaowan discovered this and asked her not to approach. Or at the moment when the warm current rushed in, Wang Xiaowan noticed the movement behind her, so he asked her to leave quickly.

It's just that this signal was misunderstood by Luo Xiaobei.

However, even if it did, it was too late.

When Luo Xiaobei woke up, it was dark in front of him.

Although he couldn't see it, Luo Xiaobei was sure that he was lying in the water.

The cold and damp touch coming from under her, as well as the buoyancy that lifted her whole person, was undoubtedly water. The smell of damp and rotting wood in the air is invisible, but it makes the sense of smell and hearing more obvious.

Luo Xiaobei stood up, and the position of the water was probably on his knees.

She thought for a moment and pulled out a tiny lighting device from the waterproof bag she had strapped to her body.

It was originally prepared, but as soon as he took it out and opened it, the darkness in front of him briefly swallowed the light, and after a while, Luo Xiaobei adapted to the scene in front of him.

There was a sound of hula water behind him, and Luo Xiaobei looked back. I saw Wang Xiaowan, who was as wet as her, standing behind her, obviously just woke up.

With the light, she walked towards Luo Xiaobei's side.

"Looks like we've stumbled into the secret passage by mistake." Wang Xiaowan sighed, as for the sudden accidents before, she didn't want to say any more, because the important thing right now was that the two of them were in the mausoleum.
