Yun Tian didn't say much, he left with a broom, Yang Sanliang was stunned for a moment, and then shouted: "Since you are on duty at night, then you might as well take this meal!"

Yun Tian waved his hand back and said, "I brought food with me, I don't need these!" After speaking, he disappeared outside the courtyard gate.

Yang Sanliang looked at Yuntian's back and was cold for a long time, before he withdrew his hand holding the food box, put the food box on the table, lifted the lid and sniffed deeply, and praised: "It's so fragrant, button meat, tofu, stewed meat, pickled vegetables, it's really good to look and taste, this fool has even missed so many good things, it's really simple, but it's just cheap for me, hehe, you can have a good meal tonight, and then sleep beautifully, this life is not too happy." ”

After saying that, he tore open the stool and feasted on it.

Yun Tian came to the library hall alone, and it happened that the steward in charge of the daytime guard was already waiting a little anxiously, and was patrolling back and forth in the hall with his hands behind his back.

Yun Tian hurriedly walked over, arched his hand at the man, and said, "This steward, below is a newly recruited miscellaneous disciple, who is here to guard the library hall as a night duty disciple, and can also help the Fu Master to help." ”

"What about Yang Sanliang?"

"Yang Sanliang has something to do, so I'll be on duty tonight!" Yun Tian said with a smile.

The steward frowned, nodded to Yun Tian, and said, "Ah, then you will be on duty tonight!" After speaking, he refused to explain more, and left without looking back.

Yun Tian watched the man leave in a hurry, just shook his head, but did not speak, but went straight into the library hall.

Because of the rules of the guild, the library hall must be on duty at night to close the door, and the departing steward is responsible for opening a closed circle, so that people outside can't get in, and people inside can't get out, and the entire library hall becomes a completely closed space.

Yun Tian watched the man carefully close the magic circle, he just felt funny, in fact, it was easy for him to break the magic circle, after all, for a genius like him, the level of this magic circle was still very poor, and it couldn't stop Yun Tian from a single bit.

However, at this time, the circle was closed, and the library hall became a completely enclosed space, allowing Yun Tian to walk in it completely freely.

Of course, there are formations between the different levels of the library hall, and the people who are allowed to enter at different levels are different, but even if these formations are a little difficult, they can't stop Yuntian all the time, as long as there is a buffer for a while, he can open these magic circles.

Therefore, the entire library hall is actually presented in front of Yuntian without reservation.

The known rune system, including paper runes and dao runes, each has nine grades according to the level, and as for the more advanced spirit runes, it is said that they are all things that only exist in the fairy world.

There are six colors of the symbol, which are yellow, red, silver, black, purple, and gold. Each type of talisman corresponds to three grades, the first to third frets of paper runes are yellow, the fourth to sixth frets of paper runes are red, the seventh to ninth frets of paper runes are silver, the first to third rank of the road runes are black, the fourth to sixth rank of the road runes are purple, and the seventh to ninth rank of the road runes are gold.

The higher the level of the rune, the more difficult it is to refine, which requires a higher-level rune master.

The level of the rune master is measured according to the level of the rune that can be refined, and those who can refine the first to two grade paper runes are called one-star Dao runes, those who can refine three-to-four-grade paper runes are called two-star Dao runes, those who can refine five-to-six-grade paper runes are called three-star Dao runes, those who can refine seven-eight-grade paper runes are called four-star Dao runes, those who can refine nine-grade paper runes to one-grade runes are called five-star Dao runes, those who can refine two-to-three-grade road runes are called six-star Dao runes, those who can refine four-to-five-grade road runes are called seven-star Dao runes, those who can refine six-to-seven-grade road runes are called eight-star Dao runes, and those who can refine eight-to-nine-grade Dao runes are called nine-star Dao runes。

The power of the talisman varies greatly depending on the level, and the paper rune of the first grade can only play a small buff role, and the gain of the paper rune of the second to third grade is quite large. When it comes to paper talismans above the fourth grade, the power can open the stele and crack the stone, hurting people in an instant. And the paper runes above the seventh grade have a strong inhibitory effect on the creatures of the dark system, and the so-called demon catching and ghost hunting generally rely on the paper talismans above the fifth grade. The nine paper runes are also divided into three levels, the yellow paper runes of the first to the third frets are called the small runes, the red paper runes of the fourth to the sixth frets are called the middle grade runes, and the silver paper runes of the seventh to the ninth frets are called the upper grade runes.

As for the Dao Talisman, it is a higher existence, the Dao Talisman is a talisman that can have characteristics similar to small supernatural powers, and its material is no longer limited to paper, so its power is also increased. Like the paper runes, the nine grades of the Dao Talisman are also divided into three levels, the black Dao Talisman of the first to third grades is called the lower grade Dao Fu, the purple Dao Fu of the fourth to sixth grades is called the Middle Grade Dao Fu, and the gold and silver Dao Talisman of the seventh to ninth grades are called the Upper Grade Dao Fu.

Paper talismans need to be pronounced incantations, but Dao talismans can be instantaneous, and the lethality is naturally not the same.

The refining of the talisman is extremely difficult, because it is just an ordinary talisman paper, and it can be transformed into a powerful medium through the steps of drawing spells, enchanting spirits, composing, and initiating formations, which is quite a difficult thing.

Especially those powerful talismans, they can even emit the power of moving mountains and reclaiming the sea, and such a huge power is usually only hidden in a thin talisman, you can imagine how amazing this is.

The refining of the rune, the higher the level, the greater the power, but correspondingly, the greater the risk of refining, and there are not a few rune masters who accidentally die during the refining of the rune. And the rune master is not for everyone to do, which requires a natural ability to communicate with the natural world, this ability can only be reflected in a very small number of people, this kind of factor, makes it extremely difficult to become a rune master, in the refiner, alchemist, rune master and array mage of the four special professions, the rune master is the second most difficult profession after the formation mage, so the number of rune masters has always been extremely rare, which makes the price of the rune has been high.

Dao runes are powerful, but they are extremely difficult to refine, so it is extremely rare to be able to refine Dao runes above five-star rune masters, even in the rune hall of the Moyang City Guild Association, there is only one person who has reached this level, of course this person can't come to the Chengnan Branch, the chief rune master of the Chengnan branch is a four-star Dao rune master who can refine seven-grade paper runes.

As for the others, most of them are two-star and three-star Dao rune masters, and some one-star Dao rune masters and rune apprentices are miscellaneous for these people, but this time Zheng Tiehan shouldered the pressure of the guild and decided to pull out these one-star Dao rune masters and rune apprentices to refine the runes to make up for the lack of people's hands, but the level of the refining runes will be conceivable, I am afraid that those one-star Dao runes and rune apprentices are even very difficult to refine two-star paper runes, and whether the refined things can be used or not is not to be said.
