"So working backwards, if there are many, or even almost all of them in soft-shell packaging, what happens when I pull out a book?"

Feng Yan's gaze fell on the empty space where the book had just been pulled out, and he quickly came to a conclusion: if it was all soft-shell packaged books, after pulling out a book, the empty space that was pulled out would be covered by the books from both sides that immediately collapsed. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Feng Yan smiled, looked closer to the empty place, and found that it was dark and could not see the bottom, but the bookcase should not be too wide, almost the same width as the book, so Feng Yan reached into it without any worries.

But after the hand reached in, something unexpected happened to him, after half an arm was stretched in, he still didn't touch the bottom, Feng Yan was a little surprised, but he was not afraid, he simply stretched his whole arm in.

"Is it the same as the rabbit hole setting?"

After Feng Yan's whole arm reached in, he still couldn't touch anything, just when he wanted to draw a circle to touch whether there were other objects around him that could be touched, a pair of cold hands instantly pinched his wrist, Feng Yan frowned slightly, but did not make any radical behavior, two seconds later, Feng Yan felt a finger trying to write on his palm, Feng Yan immediately opened his palm completely with great cooperation.

“1~1~8~”

Although the speed of finger writing is very fast, the numbers written down are very simple, and after writing these three numbers, the hand that grabbed Feng Yan's wrist immediately released.

Feng Yan withdrew his arm, there was no number on the palm, it seemed that the guy who was writing on his hand just now, his fingers were not painted with some paint or something, this hint was just for the player to feel.

Feng Yan thought for a moment, took the book and said quickly: "Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxyfluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chloride, argon, potassium, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, ......"

118 is the number of all the elements in the periodic table, which is not difficult to guess after combining the chemistry books in his hand, but what Feng Yan doesn't know is that the system needs him to read out which groups of elements, so Feng Yan chooses to memorize them all until he recites the conditions required by the system, which is trivial for him, he remembers all the 118 elements, not only remembers, but also writes them all, of course, many people can also do this.

When Feng Yan read the sixth group of elements, the book in his hand glowed blue, and he saw a middle-aged European man dressed in gorgeous clothes appear in front of Feng Yan's eyes, and it was less than two minutes at this time.

This middle-aged man wears a crown, is dressed in the costume of the nobility of the ancient European court, and wears a crown on his head, it is not difficult to judge that this guy should be a king or something.

"Hey friend, my name is Charlemagne, your time is running out, we can't afford to waste it, I know what you want...... From here, you can teleport to the recipe area. ”

Feng Yan looked at Charlemagne, bowed slightly, as a sign of respect, and said in his heart: It turned out to be this hero.

"Dear Charlemagne, as you say, please help me."

Charlemagne paced two steps in satisfaction and said, "My friend, I understand that you are desperate to find a way to teleport, but you must solve the puzzle, and only those who have wisdom are qualified to get the way to teleport. ”

Feng Yan hugged his arms and immediately said, "Please ask the question." ”

Charlemagne smiled and said, "Please tell me exactly where my sword is, you only have one chance." ”

Charlemagne did not have a sword on his body, he was only wearing a gorgeous costume, and a sword had to be at least nearly 1 meter long, if he hid it on his body, he would definitely be seen at a glance, at this time, there was obviously no possibility of a sword, then his sword could be located anywhere in the library, Charlemagne actually asked Feng Yan to tell where his sword was hidden, there was only one chance, the second wave of book spirits would appear soon, and there was not enough time, which was obviously a bit embarrassing.

Feng Yan only thought for less than 10 seconds after listening, and then pointed to his temple and said, "The saber is hidden in your head." ”

Charlemagne showed a surprised expression, then clenched his right hand into a fist, pointed the fist to his temple, and pulled it outward, and in an instant, a saber about 1 meter long was actually pulled out of his temple by him, which was similar to magic.

Charlemagne, with his sword in hand, said with some incredulity: "Oh God, my friend, how did you guess it?" And so fast! ”

Feng Yan stretched out his index finger and shook it and said: "I'm not guessing, I have a factual basis, guessing is too low-end for me, Charlemagne, say your name alone, not to study history, many people may not have heard of it, but I want to tell your other identity, that is almost a household name." ”

Charlemagne shrugged his shoulders and said, "The character on the King of Hearts is me." ”

Feng Yan nodded: "The red heart KING on the playing card is designed based on you, on that card, you hold a sword hilt, located in the head position, the blade is only exposed a little, the rest of the blade seems to be hidden behind the head, in fact, it enters your brain, if it is only hidden behind the head, it is impossible for the blade not to stretch out from the other side, the card is drawn like this, this is my speculation." ”

Charlemagne clapped his hands and said, "Sure enough, a very smart friend, then don't waste your time, do you see the ten spotlights above the bookcase?" Adjust the angle of the third spotlight to level and you will be teleported immediately. ”

Charlemagne gradually disappeared, the spotlight at the top of the bookcase is the kind of small round lamp that can be adjusted by hand, and if you want to adjust the light to which angle, you only need to flick it with your hand, and the spotlight is facing outward at an angle of 45 °.

Feng Yan couldn't reach the spotlight at the top, he decisively pulled out a few thick and big books, put them under his feet, and pushed the spotlight to a horizontal state after stepping on it, and instantly he only felt a suffocating spasm, accompanied by a dark in front of his eyes, this feeling only appeared for a few tenths of a second, and the next moment he regained consciousness, looked up at the bookshelf in front of him, which were all recipe-type books, it seemed that he had come to the recipe area, at this time, on the bookshelf in the recipe area, many books were glowing with blue light, and they were dazzling for a while, And at this moment, the countdown is over.

"Roar~Roar~Roar~!!"

I heard many roars that shook the world, these roars were very low, and with a hissing sound, the whole library seemed to tremble, and then Feng Yan only felt that a big thing was rushing in his direction, the reason why it felt huge was because Feng Yan felt that when this monster ran up, the ground was shaking, but the amplitude of the vibration was somewhat similar to friction, this sound was caused by huge friction, and the ground vibrated at low frequencies. It didn't take long for Feng Yan to know why this tremor was happening.
