I fell through the tunnel and brought my family to live a good life

Xu Congyi carefully put the envelope and the scroll back into the space, and then quickly returned to Shen Xiao's side. She knew that time was running out and she had to find more clues as soon as possible. In the dim study, hands are more practical than eyes. The two began to carefully feel the walls, floors, bookshelves and other places in the room where clues might be hidden.

Xu Congyi moved slowly along the wall, her fingers searching for any possible bumps or depressions on the rough stone wall. She noticed that a few books on the bookshelf were arranged too neatly, and she always felt that they were different from the other books. She gently moved the books, trying to find the mechanism hidden in them.

Shen Xiao knelt on the ground, tapping the ground with his palms, trying to judge whether there was a mechanism or a secret compartment by the change of sound. The two kept groping and exploring in the study. Although their fingers were a little painful, they did not give up. They knew that every detail could be the key to solving the puzzle.

Finally, during one of Xu Congyi's attempts, she discovered something strange on the bookshelf. It was a seemingly ordinary and inconspicuous ornament, quietly placed in a corner of the bookshelf. Compared with the surrounding books and decorations, it was not eye-catching. However, when Xu Congyi reached out to touch it, she found that it seemed to be firmly fixed by an invisible force, and no matter how hard she tried, she could not move it. Xu Congyi rubbed the ground with her feet, and Shen Xiao, who was kneeling on the ground, immediately came to her side. Shen Xiao carefully observed the position and shape of the ornament, and then tried to turn it with his hands. He felt a subtle vibration coming from the ornament. At the same time, the floor under their feet seemed to be slightly loose. The two looked at each other and saw the surprise and nervousness in each other's eyes.

Then, they found that a piece of floor under the desk was slowly sinking. As the floor sank, a dark hole gradually appeared. The hole was pitch black and bottomless, as if it led to another unknown world. A cold wind blew out of the hole, bringing with it a damp and cold breath that made people shudder.

Xu Congyi's heart suddenly sank. She couldn't help but frowned and whispered, "Why does it feel completely different from the secret passage in the warehouse?" This was not her illusion. When the secret passage in the warehouse was opened just now, it didn't feel damp and cold. Instead, it was filled with an old dusty smell. And now, this damp and cold feeling made her think of the water dungeon she had seen in novels before.

Shen Xiao also thought of this possibility. He did not rush to act, but first lay on the ground and carefully sniffed the wind blowing out of the cave. He frowned and confirmed that it was just a damp and rotten smell, and there was no fishy smell common in the water dungeon. This slightly alleviated his worries, but he still remained highly vigilant.

Shen Xiao looked back at Xu Congyi and said seriously, "I want you to wait for me up there. I'll go down and check the situation first." However, Xu Congyi shook her head firmly. She knew her own abilities very well. If she was there, she could quickly use her abilities to bring Shen Xiao back to a safe space when in danger. But if she wasn't there, once Shen Xiao encountered danger, it would be like a sheep in a tiger's mouth, unable to escape.

In the end, Shen Xiao decided to let Xu Congyi follow him. He took a deep breath and led the way into the narrow cave. Because the cave was narrow and deep, they did not dare to turn on the flashlight rashly, for fear of causing unnecessary trouble. Therefore, they could only rely on the weak natural light and their tacit understanding to carefully walk down step by step.

After both of them entered the cave, Xu Congyi dared to turn on the darkest flashlight. The dim light illuminated the surrounding space, but it still could not penetrate the bottomless darkness. They walked down slowly, one in front and one behind, following closely.

When they reached the bottom, they found the source of the damp and cold air. There was actually an underground river flowing slowly, with a dim light flickering under the water. Shen Xiao and Xu Congyi looked at each other and knew that this underground river was most likely a secret passage connected to the outside world.

"It seems that Old Tang also knows that he has done a lot of bad things, and he has even arranged a way out." Xu Congyi patted the stone wall lightly, with a bit of ridicule in his tone. Just now she was worried that this would be a water prison, but now seeing this underground river, she felt much more relaxed and could even joke with Shen Xiao.

The two looked around below, and found nothing special except the underground river and the surrounding stone walls. They decided to go back up, but before that, to be on the safe side, they decided to take another careful look at the stone walls.

Now they could turn on the flashlights and carefully observe the stone walls. Two people, one on the left and one on the right, slowly moved forward along the stone wall. The light of the flashlight swayed in the darkness, illuminating their way forward. They carefully observed every inch of the stone wall, looking for possible clues or mechanisms.

However, after a careful inspection, they did not find anything unusual. The textures and patterns on the stone wall were very ordinary, without any special marks or hints. They knew that this trip was not in vain, at least they had found the underground river and confirmed that there was no other danger in this place.

So they went back up there, turned off the flashlight, and turned the ornament back to its original state. As the ornament turned, the hole was sealed again, as if this secret place had never been discovered.

The two continued to search for a long time, but could not find anything for the time being. It was getting late, so they decided to go home. Before leaving, Xu Congyi took the books on the bookshelf that she had just felt were wrong. When she went back and looked carefully, she might find other clues. In order not to be discovered so quickly, she found a few other books from below to fill in the gaps and pretend.
