Of the five people who were still together just now, there are only three left.

In order to prevent anyone from falling into the trap again, Yu'er clenched the cold hand of the other girl, and she handed her hand to Nangong Rushi, but was rejected by Nangong Ru arrogantly.

The three of them walked another stick of incense in the secret room, and at the end of the narrow secret room, it was a dead end with four walls. They had to look for mechanisms on the walls near the chamber.

Yu'er and Nangong Ru groped around the walls for a long time and didn't find anything unusual. Just when they were helpless, another girl was lucky enough to find an escape mechanism. She secretly rotated a stone in the corner of the wall to one side, only to see that one of the walls suddenly opened a gap, and the girl did not tell Yu'er and Nangong Ru, but walked sideways into the crack in the wall and closed the stone wall again.

When Nangong Ru and Yu'er noticed it, the girl had already left the secret room.

"Sure enough, you can never rely on others!" Nangong Ru's face was solemn and said coldly.

"Perhaps...... Maybe she didn't mean not to tell us how to escape! She tried to defend the girl who had fled alone.

"Probably only a fool like you would say such stupid things." Nangong Ru said as she bypassed the wall where the girl had disappeared just now, and caught a glimpse of the stones that had been moved in the corner.

Nangong Ru leaned down and gently turned the stone, and the crack in the wall opened again.

When she followed her to look, she suddenly heard a girl's scream in the crack in the wall, and saw that the stone slab inside was cracked again, and before the two of them could see clearly, they closed it again.

Nangong Ru guarded outside the crack in the wall and did not enter, she looked at the environment inside, but saw that there was another secret room inside, judging from the speed at which the girl entered the inner passage and the footprints on the dust on the ground, after the girl entered the inner passage, she did not touch the walls on both sides, and the mechanism of the inner trap, according to her speculation, should be a certain stone slab on the ground.

Nangong Ru was pondering, and the cracked wall suddenly closed, and a heavy stone wall suddenly fell from the side where she came, trapping her and Fu'er to death.

"How so? Is there still a mechanism? She exclaimed.

As the stone walls fell, four bronze finch heads poked out from the four corners of the four walls, and water was bubbling in the mouth of the bronze finch and slowly poured into the small secret room.

"Not good! We need to find the mechanism and get out of here, or we'll drown here!" Nangong Ru shouted loudly.

Yu'er obediently followed Nangong Ru to grope on the four walls.

After a while, the water was not even above the waist of the child.

She struggled to find a mechanism to get out of the water. When she looked up at the Bronze Sparrow's Head, she stumbled upon a somewhat abrupt stone brick underneath the Bronze Sparrow's Head.

"Look, sister!" She pointed her hand to the stone brick in the high place.

Nangong Ru was extremely surprised, and sighed: "Maybe that stone brick is the mechanism to open the secret room!" ”

Nangong Ru, who was taller, tried to tiptoe and reached for the stone bricks on the wall. But the stone brick was too high for one person to reach.

Nangong Ru turned around and said to Yu'er: "Quick! You climb on my shoulder, and I carry you to the brick! ”

Yu'er agreed, climbed onto Nangong Ru's shoulder with difficulty, and stretched out her little hand to reach the stone bricks.

The water had already covered Nangong Ru's chest.

"Quick! It's just a little bit close! Nangong Ru worked hard to support it, using up his last strength.

She tried again, reaching out and holding down the stone brick.

The head of the bronze finch stopped filling the water, and the water in the chamber flowed along the depression at the edge of the four walls, and the current gradually receded. I only heard a "squeak", and one of the stone walls opened, and the long-lost sunlight poured in.

Fu'er and Nangong were exhausted, and they fainted by the door of the secret room.
