Human race, but was chased by girls from all races

"Well...how about I fly over there and see what's going on?" Long Xinyu suggested. The red-haired girl was already eager to try.

"No, you stay here, I'll go." Lin Tianlang said. After that, he took out the dragon crystal and merged it into his body. Dazzling golden dragon wings grew out from Lin Tianlang's back. Seeing this change, the puppet housekeeper's expression did not change at all, and he looked calm.

"Wait for me here, I'll be back soon."

Lin Tianlang spoke to the girls behind him, then flapped his wings and flew towards the library built on the mountainside.

The lake surface on Bajiao Island is obviously different from that on Giant Island. In other words, given the vastness of the water surface, it is no longer appropriate to call it a "lake surface". It may be more appropriate to call it a sea surface. The sea water in this sea area is churning violently. Just below Lin Tianlang, the sea water is constantly rolling, and various turbulent currents form white whirlpools. Once you accidentally fall into it, you may not know where you will be washed to.

It is not suitable to sail on such a rough sea, so this also strengthened Lin Tianlang's determination to use flying as a method.

It didn't take too much time to fly from the shore to the cliff library, just one or two minutes. When flying to the cliff library, Lin Tianlang saw a small platform. He flew around the library and the entire towering rocky mountain, observed the terrain, and found that this library was really strange.

Based on what Lin Tianlang observed, it was impossible for this library to be built here according to common sense, because this rocky mountain was too steep, and the construction here was extremely difficult. Even if magic could be used to build it, it was still the same. Therefore, the first impression that Lin Tianlang had of this library was that it seemed to be generated on the spot. However, this psychedelic mirror world itself was not the real world, but a world created by old Principal Mace, so it was not surprising that there would be such a spectacle.

After the first round of observation around the cliff library, Lin Tianlang had a rough idea in his mind. The small platform in front of the cliff library can be used for landing, but because the area of ​​the platform is a bit small, it is a bit difficult for Long Xinyu to land in the form of a dragon. It seems that he can only land here in human form.

After coming up with an idea, Lin Tianlang turned around and flew back to the shore.

"how is the situation?"

After landing on the shore, the girls gathered around and asked.

"Just like I said." Lin Tianlang said, "The only way to get there is by flying. The sea conditions are too bad, and most importantly, the cliffs are too steep to climb up. So since it's like this, we might as well just fly over there."

"But there is a problem with flying. There is a small platform in front of the library where we can land. But the area of ​​the small platform is very small, so if Long Xinyu lands in dragon form... it will be a bit difficult. In other words, we can only fly over and land in human form."

Lin Tianlang explained in detail.

"You mean, I can't turn into a dragon and carry everyone over?" Long Xinyu said.

"Yes." Lin Tianlang nodded: "You can only fly in half-dragon form and carry one person at a time. In other words, we have to fly twice."

"Of course I have no problem." Long Xinyu said, "Then shall we set off now?"

"Yes, let's go now." Lin Tianlang nodded. He looked at the other four girls except Long Xinyu: "Then... who among you will be the first to go?"

"Let me go first." Xu Weiwei volunteered.

"And me." Shirley followed closely behind.

"Okay, then let's not waste time and go now." Lin Tianlang nodded.

"Xuexue, I'll take you with me!" Long Xinyu said with a smile, hugging Shirley's waist. Having been deskmates for a school year, Long Xinyu and Shirley have a very close relationship now.

"Okay, then I'll leave it to you, Xiaoyu." Shirley nodded with a smile.

"Then I'll take Xu Weiwei with me." Lin Tianlang nodded.

"Hey, why do you sound so reluctant?" Xu Weiwei pouted and said unhappily.

"Don't add to the drama, I didn't say anything!" Lin Tianlang rolled his eyes at Xu Weiwei, then stretched out his hands to hold the silver-haired girl's waist, and hugged the girl tightly. Although this action was not the first time, and even more intimate actions had been done before, but buried in someone's broad chest, the girl still inevitably blushed. Especially with several other girls watching, which made her even more shy.

"Let's go." Lin Tianlang called to Long Xinyu, then flew up with Xu Weiwei in his arms: "Hey, hold on a little tighter, what are you doing standing there in a daze?"

"Um... I know!" Xu Weiwei curled her lips, put her arms around someone's waist, and then when someone wasn't paying attention, she secretly pinched him/her hard.

Lin Tianlang and Xu Weiwei set off first, and after Long Xinyu transformed, he followed closely with Shirley. After bringing the two girls, Jin and Yin, to the small platform of the library, Lin Tianlang and Long Xinyu returned to the shore to pick up Qiuyue and Aniya.

The two trips took less than ten minutes. Now everyone gathered at the entrance of the cliff library. Lin Tianlang and Long Xinyu lifted their transformations and returned to their most ordinary human forms. Then, everyone walked towards the entrance together.

“Squeak~~~~”

As if sensing the arrival of everyone, the door of the library opened automatically. Everyone didn't hesitate and entered the library. In the library, there was an antique atmosphere everywhere: wooden floors, exquisite bookshelves on both sides, filled with densely packed books of various colors.

"Wow...what a beautiful library..." Seeing the scenery inside the library, Ania's eyes lit up and she couldn't help but exclaimed.

Antique lanterns are hung on the walls of the library to provide lighting. The pale yellow light spreads out layer by layer, adding a sense of ancient flavor.

"The puppet butler said that one-third of the keys are hidden in this library," said Shirley.

"Yes, that's right." Lin Tianlang nodded: "In that case, let's split up and look for it." Lin Tianlang said.

"But didn't the puppet butler say that if we want to get the key, we must solve a puzzle? I don't see any puzzles here that we need to solve." Xu Weiwei said with some surprise.

"I don't know. Anyway, let's look around first to see if there are any clues."

"..."

The group dispersed and began to search for clues in the library. The structure of the library was quite simple, just a very regular rectangle. After a quick measurement, the length of this rectangle was about 50 meters, the width was about 10 meters, and it was a relatively slender rectangle as a whole, and the height was about 4 meters.

"Hiss... Where is the key hidden?" Lin Tianlang checked the bookshelves one by one, trying to see if there were any secret doors or compartments. In the rectangular library, the bookshelves were only placed on the two "long" sides, and there were no bookshelves on the wide side of the rectangle, but a yellow-white background wall.

In this 50 square meter flat library, 10 meters long and 500 meters wide, everyone dispersed to look for clues. However, in the first round of searching, no one found any useful information.

"Did everyone find anything?"

Ten minutes later, Lin Tianlang called everyone together and asked. But the girls looked at each other and shook their heads.

"Okay, let's search again carefully." Lin Tianlang said helplessly. He himself did not find any useful clues. But to be honest, this 50m x 10m rectangular library has two layers of densely packed bookshelves. If there is a secret compartment in one of the bookshelves, or even a book that is the switch to activate the hidden door, then it would be very difficult to find it.

Everyone dispersed again to look for clues. At first, there was no clue, so everyone could only use the least efficient method - taking out the books from the bookshelf one by one and eliminating them one by one.

"These books... why are there nothing in them?" Long Xinyu's voice rang out. The red-haired girl held a thick ancient book in her hand, and the title was incomprehensible. But this was not the point. The point was that the content of the book was empty. Inside the paper, every page was blank.

"Let me take a look." Following Long Xinyu's voice, Lin Tianlang ran over.

"Look, the content of the book is empty." Long Xinyu held up the book and showed it to Lin Tianlang: "You say, this is a library, why would there be such an empty book with no content?"

"Is every book like this?" Lin Tianlang asked, and as he asked, he quickly pulled out a book from the bookshelf. Lin Tianlang also couldn't read the name of the book, which was a very obscure ancient Chinese text that Lin Tianlang didn't recognize at all. But after opening the book, Lin Tianlang also discovered that the content of the book was empty.

“Are these all empty books?”

Lin Tianlang pulled out several more books and after checking, he found that the contents of the books were also all empty.

"I think I know what the puzzle is." Lin Tianlang closed the book in his hand, then exhaled heavily and said thoughtfully: "I guess this entire library is a puzzle."
