This is what the old man called the library. It follows the simple and rigorous style of the alchemy room. There are only a dozen huge stone bookshelfs and the only stone chair in the indoor space of a standard rectangular 400 square meters. The stone rack is not wide, but its length and height cannot be underestimated. It blocks the room like huge screens, leaving only two walkways less than two meters close to the walls on both sides of the room.

The top is even connected to the roof. At the height of 1.85m, Li Yan can only touch the fourth floor of the stone rack counting from top to bottom. The interval between each floor of the stone rack is half a meter. It is filled with densely packed books and records of chopped or rolled animal skins.

Without the help of a mage, even if Li Yan develops Yao Ming's height, he should sigh at the books on the top. Don't think about using climbing to solve the problem. The electric magic circle hidden on the stone rack will make everyone who tries to do this.

The residents outside the tower spent three cycles of light and darkness in the galaxy, while Li Yan, who was immersed in the sea of ​​books in the tower, completely lost the concept of time, just like returning to his days at the Merlin Master Tower, every book and every stack of materials attracted him. With his eyes on the memory of ten lines and his rapid thinking, the original questions were explained one by one, and then marched towards new questions, repeating over and over again. This kind of pleasure of clear thoughts was extremely wonderful.

Before he knew it, he had laid a solid theoretical foundation in the field of magic circles.

At the same time, this process of absorbing a large amount of magic-related knowledge has also inadvertently brought a lot of benefits to Li Yan's magic practice. You should know that the field of magic is vast, and each step of the magician's improvement is not only spiritual power, deep consciousness, etc., but also closely related to the seemingly subtle aspects of magic element characteristics, magic network energy flow characteristics, magic element arrangement, mental power and attribute bias of deep consciousness, etc. Every time you deepen your understanding of them, it is quite flattened the rugged road ahead.

Therefore, Li Yan even had a self-mockery that life continued like this. Of course, it was just a self-mockery. The strange old man who had disappeared for three days was pressing tightly on his heart like a mountain.

"Ou Tilu's "Essence of Engraving of Magic Arrays", it seems that your vision is pretty good." The empty and quiet room suddenly echoed hoarsely, and a low voice interrupted Li Yan's thoughts. When he turned around, the strange old man was still wearing that black robe and slightly hunched back in the shadow of the aisle. He quietly didn't know how long he had stood there, his eyes staring straight at him, like a ghost.

Li Yan didn't feel surprised either. A simple "fossil into mud" made a small hole in the armrest on the right side of the stone chair, stood up and placed it gently on the book, and carefully placed it on the chair seat, turned around and saluted the old man, and said with a smile: "Hello."

"Um." The old man turned his head and snorted without hesitation, ignored Li Yan, turned around and stepped on his staggering steps, and said, "Eat your dinner quickly. At most half an hourglass, I will see you in the alchemy room. Also, don't misplace my collection! Believe me, you will never like the smell of the 'Heart Eater'."

As this sentence fell, a thick blue book flew out on its own in the corner of the stone bookshelf that the fluorescent ball had just shone on its own. After changing positions with the same blue partner close to the right, it quietly sank into dormant.

The footsteps of "pat" disappeared. After a long time, Li Yan turned his head slightly and looked at the two books exchanged back and chuckled silently. The speculation three days ago was confirmed again, and this old man was not crazy!

As for why it becomes so weird.

Subtle clues were interspersed in my mind: the magician, thin, closed in his robe, his voice was extremely hoarse, dead, his movements were stiff and clumsy, and he was very prone to anger, the Nether Fire, the Heart-Devouring Spell, but the dark aura was not strong, and he forced himself to learn the magic array.

After many analyses were ruled out, the final answer faintly emerged.

‘Is that true?’ Looking at the charming light flashing under the fluorescent light in his hand, Li Yan smiled and raised his eyebrows lightly: “The dinner time is very sufficient when half an hourglass is available, thank you.”

When he was half an hourglass, Li Yan chewed it slowly and solved the large piece of barbecue after only half of the time.

When he walked out of the library, followed the spiral stairs to the alchemy room, and then passed the door that was disguised as a wall by the illusion array, the time just passed by 1/3 of the hourglass, which was 20 minutes on the earth.

In front of the huge obsidian table, the old man bowed his head and fiddled on the table.

Walking to one end of the stone table, Li Yan carefully observed his movements.

At this time, a small rectangular rectangular stone slab was placed flat on the table, with a length, width and thickness similar to that of the iPhone 4 on the earth, and the surface was smooth and flat.

A metal pliers are clamping the sides of the stone slab, and the handle is hooked on the edge of the obsidian table like a big hook. There is also a screw that is hooked at the bottom of the table through the screw holes hooked at the bottom of the stone table, which seems to be a fixing function.

The old man was holding a triangular carving knife in his right hand, and a small magic pattern engraving pen in his left hand was working on the stone slab. It can be seen that a long dent had been cut on the surface of the stone slab, and the dent had been filled with dark purple magic carving potion. At this moment, the small ceram knife was stabbed in the stone slab under the control of the withered right hand, moving calmly and firmly.

Whenever the carving knife passes, the magic pattern engraving pen held in the left hand will quickly follow, and the stretched dent is coated with purple potion.

At this time, the old man's thin hands were no longer clumsy. Although they were a little stiff, they gave people a feeling of holding a huge and clever hand.

This is an art. Li Yan stared at the old man's movements, and even couldn't bear to blink his eyelids and reflected a detail of this scene into his mind.

Thank you Xiaoyangmanman for your reward!

Hahaha!
