Human race, but was chased by girls from all races

……

"What do we do now?"

Qiuyue looked at Lin Tianlang and asked. There was no doubt that Lin Tianlang was the backbone of the team. Facing the current situation, everyone was waiting for his instructions.

"..."

Lin Tianlang touched his chin, frowned tightly, and said nothing. After a while, he reached for the lever next to him and pulled it.

"Kaka!"

As the lever was pulled, all the doors began to rotate again, making mechanical sounds. Lin Tianlang had just pulled the lever on the left, so the door rotated counterclockwise, and now Door No. 2 had come to Room No. 1.

However, when the mechanism was completed, a new situation emerged. The entire octagonal hall suddenly shook violently, as if there was an earthquake.

"What happened?" Aniya said nervously.

"I don't know!" Long Xinyu swallowed his saliva, observing the surroundings vigilantly and on guard. However, the vibration soon ended, and at the same time, Lin Tianlang found that the pull rod seemed to have changed. Compared with the beginning, the length of the two pull rods seemed to be shorter.

"This pull rod... seems to have become shorter after the vibration." Lin Tianlang told everyone about his discovery.

"What? Let me see?" Xu Weiwei came over after hearing the voice. The silver-haired girl carefully checked the two pull rods and then said, "It seems... it is indeed shorter than before."

"Well, why don't we try to see if the door can be opened?" Qiuyue said softly.

"I'll go, I'll go!" Long Xinyu rolled up his sleeves, quickly walked to Door No. 2, and stretched out his hand towards the door handle.

"Click!" With the crisp sound of a door being unlocked, Door No. 2 was opened, revealing Room No. 1 behind it.

"The door can be opened!" Long Xinyu shouted.

This is definitely exciting news. Everyone looked at each other and breathed a sigh of relief. When everyone found that door No. 2 could not be opened just now, they were still a little worried. But fortunately, door No. 2 was not locked.

"Let's go in and see what's inside the room." Shirley said. Then, the blonde girl walked into the room. Long Xinyu followed closely behind her, searching anxiously in the narrow room.

"This room... is empty."

However, the room was only this small, and they could see almost everything at a glance. After searching around, they found that Room 1 was almost completely empty. There were no clues or even anything. There was nothing left except the walls.

"You two should come out of the room first." Lin Tianlang said to the two girls, Jin and Hong. They nodded and then left the room. After they both left the room, Lin Tianlang pulled the lever again, but this time, he found that he couldn't pull the lever, whether it was the left or the right.

"Huh? The lever is malfunctioning?" Lin Tianlang frowned.

"Ah? No way?" Xu Weiwei said, "How could this happen?"

“I don’t know. It was fine just now.” Lin Tianlang scratched his head and said.

"Could it be... because the door was not closed?" Qiuyue reminded.

"It's possible...Shirley, please close the door!" Lin Tianlang looked up and said to Shirley.

"Okay." Shirley nodded and closed the open door No. 2. After the door was closed, Lin Tianlang immediately tried to pull the lever again. Sure enough, this time the lever could be pulled normally. The mechanism started working again, and all the doors moved counterclockwise again, and door No. 2 was aligned with room No. 8 again.

This time, without Lin Tianlang or anyone else reminding her, Long Xinyu could not wait to open the door. But something strange happened again - the door could not be opened again.

"What's going on? Why can't it be opened again?" Long Xinyu scratched his head and said with a pout.

"There must be some pattern in this, right?" Qiuyue touched her chin and made her own guess: "It's possible that only when the lever is pulled a certain number of times can the door be unlocked."

"Oh - Senior, why didn't I think of this!" Xu Weiwei said with sudden enlightenment: "Perhaps, this is really possible!"

Xu Weiwei's expression became excited, as if she had found something remarkable. She hurried to the door, released her mental perception, and attached it to the door.

"Lin Tianlang, keep pulling the lever!" Xu Weiwei said to Lin Tianlang, "I'll stay here and watch to see if there will be any changes to the protective spell on the door!"

"Okay!" Lin Tianlang nodded and pulled the left lever again. The mechanism started to work, and Door No. 2 and Room No. 7 were aligned.

"It probably still won't work... The protective spell on the door hasn't changed at all, and it's still tightly sealed." Xu Weiwei shook her head and reached for the handle. Sure enough, the door couldn't be opened.

"Keep pulling the lever!" Xu Weiwei said loudly.

Lin Tianlang nodded and pulled the lever again, and then the door of Room 2 and Room 6 were aligned.

"It still doesn't work, pull it again!" Xu Weiwei shook her head and said. Hearing this, Lin Tianlang didn't say anything more, but just pulled the lever again.

Door No. 2 is aligned with Room No. 5. Lin Tianlang has been pulling the lever on the left, trying to see if there will be any effect if Door No. 2 is aligned with the doors of different numbers. But so far, nothing has happened.

"Pull again!" Xu Weiwei said again.

The lever was pulled again, and Door 2 was aligned with Room 4. But after the mechanism finished operating, something went wrong again. The same vibration as the first wave appeared again, but this time it lasted a little longer, about ten seconds longer than the first wave.

After the vibration ended, Lin Tianlang sensed something and immediately checked the pull rod. As expected, the pull rod was shorter again.

"The pull rod has become shorter again!" Lin Tianlang said loudly.

"But... the door can be opened!" Xu Weiwei's slightly excited voice rang out. Then, the silver-haired girl opened the door No. 2, and the interior of Room No. 4 immediately became visible. However, like Room No. 1, there was still nothing in Room No. 4.

"I roughly guessed what happened!" After briefly checking the interior of Room 4 and making sure there was nothing inside, Xu Weiwei stepped out of the room and closed the door. The corners of the girl's mouth slightly raised, revealing a triumphant smile: "When the vibration happened just now, I found that the protective magic that was originally effective on Door 2 suddenly dispersed and spread the power to the other doors, making the protective magic on the other doors stronger, while the protective magic on Door 2 was ineffective."

"So... every time a vibration occurs, the door can be opened, is that right?" Shirley asked.

"Yes, that should be it!" Xu Weiwei nodded. "I just counted it. Every time we pull the lever five times, that is, every time the door moves five times, there will be a vibration. Therefore, every five times is a group. Every time we pull the lever for a group, the door will have a chance to open. If a group is not completed, the door cannot be opened."

Xu Weiwei analyzed it clearly and the smile on her face became even brighter.

"If that's the case, then we can make use of this mechanism." Lin Tianlang nodded: "However, after each vibration, the pull rod will be shorter. What's going on?"

"Sirius...if my observation is correct, this pull rod...seems to be a quarter shorter than at the beginning." Shirley pursed her lips and said softly.

“A quarter shorter…” Lin Tianlang frowned and thought for a moment.

"If we continue at this speed and the vibration happens six more times, the pull rod will be shortened to nothing." After thinking for a long time, Lin Tianlang came to this conclusion.

"That's right." Xu Weiwei nodded and agreed.

"What's right? This shouldn't be right, right?" Long Xinyu shouted, "If there are six more earthquakes, the pull rod will be shortened to nothing. Without the pull rod, will we be unable to control the movement of these doors? Will we be trapped here?"

"Xiao Yu, you're right, that's it." Xu Weiwei nodded, but there was no sign of frustration on her face: "This is the difficulty of this puzzle. That is to say, we initially had 8 chances to try. But we have already used two of them to discover the secret of the mechanism. So we need to use the remaining 6 chances to move Door 2 to Room 8 to take the key, and then move Door 2 to the exit to complete the escape."

"Hiss... Hearing you say that, I feel like it's a bit like solving a math puzzle." Lin Tianlang scratched his head and said. The current scene brought back painful memories of his middle school years when he was studying math.

"Haha, that's right! You're absolutely right, this is a math problem!" Xu Weiwei said with a smile, "And now Door 2 is aligned with Room 4, which is right opposite Room 8."

"So we need to make sure that Door 2 is aligned with Room 8 after a certain vibration in the next move. In this way, we can open the door smoothly, walk into the room, and take out the key."

"Oh this... bad, the dead memories are starting to attack me..." When thinking of mathematics, Lin Tianlang rubbed his temples with a headache. In middle school, mathematics was his lifelong enemy, not to mention that after coming to the magic school, he hadn't touched a math problem for 4 years...
