On the second floor of the library, although the collection of books is much smaller than that on the first floor, there are no new manuscripts here, and they are all original works with a sense of vicissitudes.

Leo followed behind Master Linyana, his heart beating with each book he scanned, and he realized that he had never seen any books before.

Master Linyana didn't stop, she continued to walk inside, and soon she was on the stairs that led to the third floor.

Leo was excited, and the books on the second floor made him yearn for it, but what about the third floor?

bang

The defenseless Leo was blocked by a transparent film, and because he was not guarded, he was directly shocked and retreated, and his right hand touched his sour nose with a look of surprise.

Master Linyana heard the movement behind her, and when she saw Leo's loss, she smiled, returned to the second floor and threw Leo a crystal: "Take it, this is a passage crystal, which can give you access to the third floor, but it only has the right of personal passage." ”

Leo was a little disappointed when he took the crystal, he thought that with this protective spell that could open the book, he didn't expect that it could only be used for passage.

The two climbed to the third floor, Linyana greeted and walked to the side of the cubicle, Leo raised his eyes to look at the books that exuded an inexplicable fluctuating aura, and tears flowed down his eyes just by looking at him, these books were obviously not what he could read now.

In the cubicle, Leo rubbed his astringent eyes, Linyana looked at it with a smile, and only when Leo recovered did she laugh and said, "Boy, don't look around, there are some things that a little apprentice is not qualified to see." ”

Leo didn't have long wisdom, he said unwillingly: "Knowledge is the ladder to find the truth, whether it is a wizard or a mage, in the face of knowledge, they can't resist the temptation in it." ”

Master Linyana nodded in agreement and said, "Leo, I came to you because I have a doubt that has not been resolved, and you can directly mention the reward." ”

Accident, quite unexpected, Leo guessed for a long time and didn't guess in this direction, there are two golden threads on Master Linyana's white robe, which means that the other party is a second-level mage, will there be doubts and can't solve it?

"My lord, I don't know why I need Leo's help. ”

Master Linyana said: "It's your thing that can emit light, I have tried many methods, even if it is exactly the same as your design, it can't make it glow, on the contrary, it will burn, I want to know why?"

It turned out to be this, Leo knew in his heart, and he said bluntly: "My lord, can you contact Teacher Saiya?

"Hehe, I knew you were going to ask about him. Linyana had a really such expression, "Okay, I'll tell you what you want to know if you solve your doubts." ”

Leo nodded, "My lord, can you do it again?" so that I can find out why." ”

Master Linyana nodded, opened a door in the compartment, and walked in with Leo.

In the laboratory, Leo looked at the meticulous Master Linyana seriously, and when the other party had done everything, he stopped the other party's action of powering up, "My lord, it's enough to get here, I already know the reason." ”

"You know?" Mage Linyana was surprised, the other party knew before the experiment was completed, which meant that she had made a mistake in the previous steps, but she didn't know what was wrong!

"My lord, the carbonized bamboo wire can emit bright light when it is electrified, but it must be in advance of the vacuum, otherwise the high temperature it produces will burn in combination with oxygen, which is why the bamboo wire is placed in a glass cover. Leo explained.

Venerable Linyana looked like she had seen a ghost, and she shook her head violently and said, "Impossible, this is simply impossible. It is a natural phenomenon that when light is generated, there will be temperature, and there will be no temperature without air. It's like a fire spell, it only burns when it's in the air, it produces bright light, and what kind of oxygen are you talking about?"

The composition of air Leo did not find relevant knowledge in this book, he nodded: "There are many different gases in the air, oxygen is a component of gas, and there are not only oxygen but also carbon dioxide, hydrogen and other gases in the gas. ”

"Carbon dioxide, hydrogen?" Linyana was shocked, and she looked directly at Leo with her eyes like electricity, "According to you, how do you separate these gases?"

This stumped Leo, what he said is very common knowledge on the earth, and he doesn't know if he really wants to analyze it in depth, and after thinking about it, he said: "I don't know how to tell the difference, but there are some simple ways to produce these gases." ”

"What method?" asked Linyana anxiously, this was a completely new body of knowledge, could she not be in a hurry.

Leo smiled silently, he was not stupid, enough to say this, no matter how much it was, it would not be as simple as two lips touching each other.

'This little bunny. Lin Yana scolded in her heart, a unique knowledge is already very expensive, not to mention this new knowledge system, she said: "Boy, what do you want, be happy, don't let the old body get angry." ”

"I want access to all the books in the library. "It's not loud, but the content is appalling.

"What did you say, did you hear me right!" said Master Linyana's eyes widened, and she almost killed the little rabbit cub with a bolt of lightning.

Leo had to repeat: "I need access to all the books in this library." ”

"No way, do you know how many systems of knowledge, how many unique books, how many secret texts there are in the library? It's impossible if you want to exchange one for all. Master Linyana roared, her eyes shining with thunder.

Shouting prices all over the sky, sitting on the ground to pay back the money, what a junior high school student knew in his previous life, how could Leo, a person who was affected by the impact of big information, not know, he said: "My lord, do you know how wide the coverage of this new system is? Let me say a little, it is also a point in the failure of your experiment, after the carbonized bamboo wire is electrified, it produces high temperature and combines with oxygen and burns, so is this the direction of the conversion of lightning energy to fire energy?"

Venerable Linyana was struck by lightning, and there have been this kind of research on energy conversion for a long time, because all kinds of magic have proved that it can be transformed, but these are still occasional natural phenomena, and no one has really done a concrete experiment yet.

"Wait, it's not up to me to call the shots. After Linyana finished speaking, she ignored Leo and took out a contact crystal and didn't know who to contact.

Leo was a little surprised, his original intention was to bargain, how could there be a turn, is it really possible for his request to be realized?

Thinking about the knowledge on the second and third floors, Leo felt a burst of excitement in his heart, if, if it can really be realized, then, then it can't be better.

After an hourglass, Master Linyana put away the contact crystal and looked at Leo, and in the face of that expectant gaze, Linyana's face was wrinkled.

She said: "Boy, the above agreed to your request, but there are a few conditions that you must agree to, otherwise this matter can only be abandoned." ”

Leo was pleasantly surprised, he didn't have any hope for this, but he didn't expect it to happen, in fact, if the other party disagrees, he will also say what he knows, and he thinks so.

"Your Excellency, you say, Leo obeys. ”

Master Linaya said, "First, knowledge can only be read by yourself, not copied. Second, the reading time is only three days. Third, you can't share this knowledge with others or leave it to future generations. Fourth, there must be a contract and you can't reveal any information to anyone. ”

The conditions are harsh, quite harsh, he can only read but cannot copy, who can remember so much in three days? Unless he forgets it, but each of these books has inexplicable fluctuations, and I am afraid that he will not be able to remember how much.

In order not to arouse the suspicion of the other party, Leo frowned and gritted his teeth and said, "I agree." ”

Master Linyana looked at Leo with some surprise, and agreed to such harsh conditions? Could it be that he was relying on something or looking for something?

The contract was signed, and Leo's performance over the next three days proved Wizard Linyana's guess, as Leo would only turn a page or two of each book before putting it back in .......
