Human race, but was chased by girls from all races

Solve three puzzles...

This is the hint given by the puppet butler. In other words, unlike the last time on Giant Island, on Octagon Island, if you want to get the world core fragments, you can't just use force, but you must use your brain. Only by using your brain can you solve these puzzles.

"I didn't expect it to be a puzzle game." Xu Weiwei pursed her lips and said in disbelief.

"Puzzle game?" After hearing this, Long Xinyu rubbed his temples: "Hmm... It sounds boring... If it's a puzzle game, I can't help you. I get a headache just thinking about these things... Hmm..."

"What kind of puzzle game is it?" Aniya twisted her fingers together and asked nervously, "Will...will it be dangerous?"

"I don't know. Just follow the instructions of the puppet butler." Shirley said softly.

"Mr. Butler, where can we go to solve these puzzles and get the keys?" Lin Tianlang asked.

"I am the butler of the Octagonal Pavilion and the person in charge of the three puzzles. If you are sure you want to challenge the puzzles, I will take you to the place where you challenge the puzzles." The puppet butler said. He is a puppet, so no emotion can be heard from his mouth, just like a robot.

"You'll take us there?"

"Yes." replied the puppet butler.

Everyone looked at each other for the second time, and finally everyone turned their attention to Lin Tianlang, meaning that he should make the decision.

"Then it seems that there is no other way at the moment." Lin Tianlang lowered his head and thought for a while: "It seems that... it feels a bit similar to the schedule of the championship."

As he spoke, Lin Tianlang looked at Qiuyue who was standing aside.

"Master, what you mean is... if the test on Giant Island is courage and strength, then the test on Octagon Island is wisdom?" Qiuyue said softly.

"From what I've seen so far, I think so." Lin Tianlang nodded: "The third round of the competition is a test of trust. I don't know what the test of the End Island will be."

"Lin Tianlang." At this time, Xu Weiwei spoke up: "I think we should first solve the things we need to do now. There is no need to think too much about other things for the time being."

"Well, you're right." Lin Tianlang nodded and agreed with Xu Weiwei's opinion: "Then we can only follow this wooden butler now. As I said, although I don't feel any danger nearby, we can't let our guard down. Is everyone clear?"

"Understood." The girls said in unison.

"Okay, let's go." Lin Tianlang nodded. He turned around, looked at the puppet butler, and said, "Mr. Butler, we are ready. Please take us to the scene where we will solve the puzzle."

"Okay, then follow me." said the puppet butler. At this time, a side door of the Octagon Pavilion suddenly opened. Not only that, a violent mechanical operation sound was heard. Everyone was shocked to find that two rails suddenly "grew" out of the ground from the opened mechanism. The rails extended to a very far place, with no end in sight.

In addition to these rails that grew out of thin air, there is also a very simple rail car. Although this rail car runs on rails, it is not a train, but more like a roller coaster in the amusement park in the human world.

Seeing all this, the most surprised were Lin Tianlang, Xu Weiwei and other people from the human world. It was known that the world of the psychedelic mirror was created by Principal Mace 500 years ago. At that time, even the human world had not yet seen trains. Who would have thought that Principal Mace had already developed a rail car!

"These... seem to be mechanical devices..." Ania bit her lip and said in a low voice.

"Mechanical technology? Are you talking about that magical technology unique to the dwarves?" Xu Weiwei blinked and said.

"Yes." Aniya nodded.

In addition to being very good at manufacturing, the dwarves also have a special technology, which is mechanical engineering. This technology can combine machinery and magic to create very powerful machines. However, this technology is too difficult for other races to learn, so it has not been fully promoted in the magic world. In particular, the overall trend of the magic world now tends to be a great integration of races. Those big cities such as the Holy City, Saint Lent City, and even slightly larger towns such as Atlan Town are all mixed races.

Only Dragon Valley City and Crescent City are still urban settlements of a single race, but such cities are becoming less and less common in the wizarding world now, and most towns are inhabited by mixed races.

It is also for this reason that the education for children of all races in these mixed cities is unified. Technology such as mechanical engineering, which is unique to the dwarves and cannot be learned by other races, will naturally not be included in the curriculum. Only the special skill of manufacturing is retained and is open exclusively to dwarf students.

"I didn't expect... to see mechanical technology here!" Ania said softly.

"In the magic world today, is there any place else where we can see mechanical engineering?" Lin Tianlang asked.

"Yes, the Mechanical City in the magic world is a city where dwarves live, just like our Crescent City." Shirley said, "I believe that in the Mechanical City, I will definitely see a lot of mechanical arts."

"Wow..." Aniya opened her mouth and said, "Where is the Mechanical City? I really want to go and see it..."

"The Mechanical City is quite far away from Saint Lent City. It seems to be more than 500 miles away." Shirley thought for a while and said.

"It's okay... I think my father mentioned this mechanical city before." Long Xinyu thought for a moment and said, "It's closer to our Longgu City, about 100 to 200 miles away."

"Let's not talk about this for now, let's go out and solve the puzzle as soon as possible." Lin Tianlang said.

Everyone climbed onto the "roller coaster" on the track. Each car could seat two people. After everyone was seated, the puppet butler activated the mechanism on the roller coaster. The train started moving, carrying everyone slowly towards the destination. As the train continued to move forward, the speed became faster and faster. Although to be honest, this speed was not much faster than Lin Tianlang's own flying speed.

"Rumble, rumble..."

When the train was running, the metal wheels collided with the tracks, making a unique rumbling sound. Then after a while, the train drove onto a huge "disc". In front of the disc, there were three track forks, each going in a different direction.

The train stopped on the "disc", right in the center of the disc.

"Adventurers, as you can see, there are three forks in the tracks, leading to three different puzzles. Please choose a direction of your choice. All three puzzles need to be solved before you can get the complete key. But there is no order in which to solve them." The puppet butler sitting in the last car of the train said to the people in front.

There are three tracks, leading to three directions. But you can't tell anything from just looking at it, so everyone didn't think too much about it and just randomly chose the leftmost direction to move forward. After the direction was chosen, the puppet butler started the plan to control the disc. The disc began to rotate, connecting the connecting track under the train with the track in the leftmost direction, and then the train continued to move forward.

“Boom… boom… boom… boom… boom… boom…”

The train sped along the track with the unique sound of wheels hitting rails. After driving for about ten minutes, the train arrived at the shore of Bajiao Island, and arrived at the destination of the first puzzle. After stopping steadily, the puppet butler said to everyone on the train: "Adventurers, we have arrived at the location of the first puzzle, you can get off now."

"Where is the puzzle...?"

Everyone got out of the car and stepped on the beach at the shore of the island. They looked left and right, but didn't find anything special. All around was yellow and white sand, just like the scene they saw when they landed. However, everyone knew that this was not the place where they first landed, but in another direction.

"Don't worry, you will know what the puzzle is soon." The puppet butler said calmly: "Over there is where you need to solve the puzzle."

As he spoke, the puppet butler pointed to the distance. Everyone looked in the direction the puppet butler pointed, and then they found out where the "place" he was talking about was. In the distance opposite the beach, there was a towering mountain. The mountain was very steep and very slender. It looked more like a towering sharp rock than a mountain, and it seemed to pierce the sky. On the mountain, there was a square rectangular building, halfway up the mountain, which looked very abrupt.

"See that library built on the mountainside? One of the three parts of the key you need is hidden in that library. And inside the library, there is a puzzle that you need to solve. After solving the puzzle, you will naturally get the key." said the puppet butler.

"Well, how do we get there?" Ania asked the puppet butler.

"You need to solve this by yourselves. I am only responsible for sending you here and then waiting for you here. After you come back after solving the puzzle, I will take you to solve the next puzzle." The puppet butler said mechanically.

"Well, it looks like it's up to us to figure it out." Lin Tianlang said. He stood on the beach and looked into the distance. The library built on the hillside was all alone, without any bridges or even a rope connecting it.

"It seems that if I want to get over there, I can only rely on flying..." Lin Tianlang touched his chin and muttered to himself thoughtfully.
