fourth

Ding Lingling took out a mask from her backpack and distributed it to several people. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 The four of them took it coughing, quickly put on their masks, and urged each other to speed up the pace of progress.

The presence of black smoke and plastic bombs made the mood of the four people anxious, and the idea of rushing out at the moment occupied their heads.

Xu Qian's right is a dead end, she can only choose to turn left at the intersection, but what makes her hesitate after turning left.

The concrete floor is exposed, with many small holes visible to the naked eye in many places, and black boxes on the left and right sides extend to the end of the road.

Xu Qian felt that something was wrong when she looked at it, and she didn't dare to take a step forward. Zhang Shaojun saw the boxes on both sides of the road and understood the reason for Xu Qian's hesitation, he walked to the front and motioned for Xu Qian to exchange places with him.

Zhang Shaojun looked around the aisle, picked up the porcelain shards on the ground, and threw them at the small holes. There was no movement on the ground, and no expected mechanism was activated. Zhang Shaojun asked the three of them to stay away from him for some distance, and then went to search alone.

Unable to determine whether the mechanism on the ground existed, he tried to avoid the holes in the ground and made it to the end of the road. He waved his hand and let the others move forward in turn.

Xu Tiannuo took a step forward, and as soon as his feet stepped on the concrete floor, the boxes on both sides opened. The two loudspeakers in the box made a cacophony of noise, and the sound resounded through the room, like the murmuring of an unsignaled television. Although the noise made people uneasy, fortunately, there was no danger, and he quickly joined Zhang Shaojun after walking down the aisle.

The other two followed, and the four of them lined up and continued to move forward, and they decided that Zhang Shaojun would take the lead.

[There are 53 minutes and 32 seconds left, and the bomb will blow up the entire room, please hurry up and escape.] 】

There is an intersection in front of the aisle, and in order to save time, Zhang Shaojun suggested that everyone move separately. He assigned tasks and precautions, and the four of them set off separately.

As Zhang Shaojun headed north, the noise of the horn continued to be emitted, which made his thinking efficiency significantly reduced. He rubbed his temples from time to time, and it seemed that the black smoke had made his body feel uncomfortable. He didn't dare to stop and continue to move forward, there were several black boxes in front of him, and there were no porcelain shards on the ground, which looked quite strange.

Ding Lingling moved towards the west, she seemed to be unaffected and jumped forward, the road was lined with wooden shelves from before, it was no wonder that she seemed so relaxed. She glanced up at the wooden shelf as she walked, looking at her watch from time to time, as if there was a way to sift through targets.

Xu Qian walked eastward, and wooden frames and boxes of different colors appeared on both sides of the road. The black smoke was getting thicker and thicker, and there was no time for Xu Qian to think, so she could only choose to move forward.

Xu Tiannuo continued to move forward with a gun, and the purple boxes around him opened one after another to reveal many strange things, including matches, gasoline, electronic scales, and so on. Everything was covered with bulletproof glass, which could not be penetrated by a bullet from a submachine gun alone. He ignored the clutter and walked straight on.

Zhang Shaojun continued to walk forward, and the black boxes on both sides opened in order, making strange sounds. The sound sounded like musical notes, and the boxes on either side seemed to be playing some song. It's a pity that Zhang Shaojun doesn't understand the rhythm of music, so he can only go straight, and the rear end of the road is blocked by an empty wooden shelf.

He took the butt of his shotgun and slammed it against the wooden shelf, trying to push it through, but to no avail. He then pulled the trigger of his shotgun, broke the wooden frame, and continued walking.

[There are 40 minutes and 03 seconds left, and the bomb will blow up the entire room, so please hurry up and escape.] 】

Ding Lingling went all the way to the west, and she walked smoothly and was not hindered by anything. She came to the wall that Zhang Shaojun had penetrated before, and used the butt of the submachine gun to make the hole in the wall wider, until a space about the size of a person was formed.

An intact metal door appeared in front of him, and there was nothing on it, not to mention the combination lock, not even the doorknob. Ding Lingling entered through the gap in the wall and observed the other half of the gate hidden within the wall.

Xu Qian walked about fifty steps, and a wall blocked Xu Qian, so she could only return to the starting point the same way.

A door appeared on Xu Tiannuo's side, and there was nothing on the façade as before, and he didn't know how to open it. He took out his walkie-talkie and told the others about the situation and stayed where he was.

The road on Zhang Shaojun's side also came to an end, and there was a big box at the end of the road. He opened the large box, and only a piano-shaped music box was placed inside. He tightened the knob of the music box, and a beautiful and familiar melody emanated from the music box.

The melody of the music box is exactly the same as the sound of the black box before!

[There are 32 minutes and 12 seconds left, and the bomb will blow up the entire room, so please hurry up and escape.] 】

Ding Lingling still didn't find anything at the door on the other side, but she saw a receiver similar to a microphone in the upper right corner of the door, and she told the others about the situation through the walkie-talkie.

Zhang Shaojun heard Ding Lingling's words, he picked up the walkie-talkie and said: "I found a music box here, and there are two rows of black boxes near it that emit music similar to music boxes, do you know what the connection is with these?" ”

Ding Lingling lowered her head and thought about it, muttering to herself: "Is the music box puzzle, I really miss it." ”

After that, she picked up the walkie-talkie and said, "Shaojun, can you take apart the music box and see what is inside?" ”

Zhang Shaojun responded and opened the music box, and after a long time, he finally found a one-line key on the back of the piano music box.

Zhang Shaojun informed Ding Lingling of the situation, and Ding Lingling asked Zhang Shaojun to come over and join her. After that, he asked Xu Tiannuo to find out if there was a small hole near the door.

Xu Tiannuo searched the gate carefully, but still found nothing, and still stayed where he was.

[There are 23 minutes and 11 seconds left, and the bomb will blow up the entire room, so please hurry up and escape.] 】

Zhang Shaojun came to her position according to Ding Lingling's prompts. Ding Lingling picked up the music box with the upper knob and aimed at the receiver in the upper right corner of the door, and when the melody was played, there was also good news from Xu Tiannuo's side.

A platform rose in front of the gate on Xu Tiannuo's side, and there happened to be a one-shaped keyhole on the platform.

All the puzzles seem to have been solved, and everything is moving in a good direction, but the black smoke is getting thicker.

The black smoke obscured almost all of the four's vision, and the trap hidden in the shadows could be triggered at any time, leaving them with little time left.

Zhang Shaojun, Ding Lingling, and Xu Qian gasped in the smoke and began to move in the direction of Xu Tiannuo.

[There are 13 minutes and 18 seconds left, and the bomb will blow up the entire room, so please hurry up and escape.] 】
