The gears glowed black and rotated continuously, and there was no apparent place on the surface where the key could be inserted. The wall www.biquge.info pen ~ fun ~ pavilion is not wide, and the two of them took advantage of the light to inspect the situation around the wall and groped forward.

There was no clutter around the black wall, and the two of them fumbled around but found nothing, and it seemed that the secret was the gear itself.

Zhang Shaojun looked at the constantly rotating gears in front of him, looking for the trajectory of its movements. Ding Lingling took out the four keys she had obtained before, and the two of them stood together and watched the gears turn, trying to find some patterns in them.

The gear keeps turning clockwise and the number on its edge is constantly changing, from 1 o'clock to 5 o'clock, then to 8 o'clock, and then counterclockwise back to 1 o'clock after 8 o'clock.

The gears then move counterclockwise from 1 o'clock, first to 11 o'clock, then to 8 o'clock, and finally to 3 o'clock. After the gear reaches 3 o'clock, it pauses for 10 seconds, and then reinvigorates from 3 o'clock.

The gear then goes around and when it returns to 1 o'clock, it spreads out at its center point. The numbers inside the gear, which represent each time period, are self-contained, separated from the center point. The scattered gear lines are precisely positioned for twelve time periods, making it more like a clock, with a large piece in the middle.

It turned out that there was an electronic screen at 12 o'clock, and the time on the screen scrolled, which was nothing more than a countdown.

The remaining time displayed on the electronic screen is 55 minutes and 13 seconds!

Zhang Shaojun just glanced at the remaining values, and did not pay too much attention to them, and the insignificant countdown could only increase the tension.

The vacant space in the middle of the gear reveals his internal structure, which is also composed of various mechanical parts, each of which does not seem to be related to each other, as if something is missing.

The mechanical parts continued to rotate, and Zhang Shaojun observed for a while and then looked at the four keys in his hand, which looked like he had some eyebrows. There are no mechanical parts inside the clock, and some strange structures can be vaguely seen, like the product of several parts combination.

Zhang Shaojun compared these structures of gears with several keys in his hand, and quickly took out the figure-7 key, and the parts composed of the figure-7 keys just filled a small part of it.

The gears, which had been separated into twelve time periods, quickly joined together and then began to spin again. The rotation of the gears is different from the last time, first idling for a turn, then starting at 1 o'clock, turning counterclockwise towards 3 o'clock.

After the gear stopped at 5 o'clock, it went counterclockwise again to 3 o'clock. Once again, the gears are separated by Roman numerals, revealing their inner structure, but the two keys inserted earlier are gone. An electronic timer appeared at 6 o'clock in the gear, and the inside was still the moving mechanical parts, but without the gaps, it was more like a whole.

Zhang Shaojun looked at it for a long time and didn't understand how to use the remaining key, and the gears relentlessly joined again to cover the internal structure, and then began to rotate in other ways.

The gears are reunited, and their trajectory of rotation is changed again. The gears went around again, then went from 1 o'clock to 3 o'clock, and finally stopped at 1 o'clock. After an interval of 15 seconds, the gears opened again, and the structure was different from the last time it was seen. Zhang Shaojun still didn't see any useful interfaces, and the gears were engaged again.

The huge gears began to spin again, and Zhang Shaojun looked confused, looking helpless about the current situation.

Ding Lingling found out about Shaojun's embarrassment, he seemed to know something, and said, "Shaojun, don't you know the ancient method of expressing time?" ”

Zhang Shaojun shook his head and said to Ding Lingling: "What is the ancient hour, I don't know!" ”

Ding Lingling walked up to Zhang Shaojun and explained to the gear: "The ancient time is similar to our current 24 hours, and the four keys we took earlier are marked with "Zi", "Chou", "Noon", and "Shen", which are converted to ancient times with modern time, and the child time is 23 o'clock to 1 o'clock, the ugly time is 1 o'clock to 3 o'clock, the noon time is 11 o'clock to 13 o'clock, and the Shen time is 15 to 17 o'clock. Based on the results I just checked, it is exactly the same as the trajectory of the gears, and we should start from this perspective. ”

Zhang Shaojun observed for a while and nodded: "It seems that you are right, finally there are some eyebrows, but how to put the key in?" ”

Ding Lingling patted Zhang Shaojun on the shoulder and said, "Shaojun, let me come here, you help me keep guard." ”

Zhang Shaojun looked at Ding Lingling's confident expression and replied: "It's rare to see that you are so confident, I'll leave it to you here." After he finished speaking, he turned his back and went back to back to Ding Lingling.

"Thank you......" Ding Linglin wanted to say thank you to Shaojun, but for some reason she swallowed it back and looked at the gears by herself.

Jiang Wenshuo walked to the edge of the cliff where the previous few people arrived, and knew that he was going in the wrong direction, so he quickly turned back. He trotted for a while. After coming to the tiled house again, he struggled for a while, and then ran to the right.

Ding Lingling's beads of sweat continued to drip from her forehead to the ground, and her black eyeballs kept turning, looking for a place to insert the figure-nine key on the loose gears. She glanced at the screen, and there were 30 minutes and 11 seconds remaining.

Ding Lingling put her head close to its interior to check, and finally saw the keyhole that matched the figure-nine key at 2 o'clock, and she quickly inserted the key into it. The keyhole is located on the edge of several mechanical positions, and it is difficult to find its location without knowing the shape and location of the key.

The spread gears combined again, this time turning several times faster than before. Ding Lingling's eyes couldn't keep up with the rhythm of the rotation, and she only knew that she finally stayed at the number of 3 o'clock, and noon and Shen were both located in this time period. The shape of the two keys is also weird, and Ding Lingling did not find a place to insert the key.

The gears are turning again, faster and faster. Ding Lingling didn't even dare to blink her eyes, tears stayed from the corners of her eyes, and this time the gear stayed at 8 o'clock. Ding Lingling probably knew that this time it was an ineffective turn, and took advantage of this gap to rub her sore eyes to let her relax.

The gears spun and slowed down, and then stopped at 12 o'clock. There was no ambiguity in the place where she stayed this time, and Ding Lingling inserted the M-shaped key into the vacancy.

She still had one last key left in her hand, the gears did not spin again, and the metal engraved with Roman numerals did not come together. It slides from the outer frame to the edge of the gear, and finally merges with the gear.

The internal structure of the gear, the delicate mechanical parts, was completely presented in front of Ding Lingling, Ding Lingling cheered up and seized the time to find the last keyhole.

Jiang Wenshuo also came to the edge of the right side of the tiled house at this time, and saw the light from the black wall, and he began to sprint like a leopard!
