Since he was determined to bear the catastrophe of the demon village, Du Xu had to make some preparations, although it was only two small roles, for Du Xu, it could be sent away.

But small characters are also organized people, and this kind of evil organization is the most difficult to deal with! In some cases, no one pursues their life or death, and sometimes, someone will come to investigate, and in the end, they often involve the behind-the-scenes boos.

Preemptively, the snake hits seven inches. If Du Xu doesn't make a move, he will definitely press the black hand behind him at a lightning speed, leaving absolutely no hidden danger.

In this case, he needs some hole cards, or even a trump card that can be hammered out.

After planning and then acting, with Du Xu, who is innate and easy to calculate, he already has this capital.

Du Xu is ready to retreat, completely refine his first magic weapon - the Wheel of Life and Death Flag, and by the way, prepare some talismans and practice some targeted spells, so as to face the mastermind behind the scenes in the future, so as to give him a "surprise" and let him reincarnate smoothly.

Of course, now Du Xu is also the teacher of the little goblins in the demon village, and he has to teach the students every day, and he is unwilling to reveal his identity, so he needs a vacation to take time.

For a private school teacher, give yourself a vacation, is it a matter?

Of course not!

Du Xu has countless reasons to give himself a vacation, and he is not a hard-working student party, so he needs a valid reason to take a vacation. Wouldn't it be nice to give students a practical assignment and keep them available for a few days?

From university professors and graduate tutors on the earth in the 21st century, Du Xu has learned countless methods of pit student labor.

Organize the thousands of books in the library!

This is an assignment that starts from the knowledge structure system and cognitive law of the knowledge system of the discipline, cultivates the construction of students' knowledge system, strengthens experimental teaching, practice and interactive links, stimulates students' curiosity, expands students' reading range, cultivates students' scientific spirit and practical spirit, and forms an assignment to improve students' learning quality and cultivate their self-learning ability.

In general, Mr. Du Xu deliberately assigned homework with good intentions in order to exercise the students' abilities in all aspects and form the knowledge system of the little monsters in the demon village.

To this end, Mr. Du Xu worked hard to compile a "Classification Outline of Library Collections", which improved the original rough classification of eight categories and upgraded it to eight outlines and 59 subheadings, each of which is divided into encyclopedias.

The students in the demon village were in tears, and they were very grateful to the teacher for their efforts without asking for anything in return, and even the old tree spirit Mu Rongsheng, who heard the news, saw Teacher Du, who had been busy for a few days and nights in order to sort out the books in the library, had a white face, and was struggling to lead the students to sort out the books, and they couldn't help but shed tears.

What a good gentleman who is dedicated and dedicated!

Lao Shu sighed silently carefully, and ordered the villagers to pull Mr. Du back to rest, and solemnly warned the other villagers and little monsters that nothing should be disturbed Mr. Du's rest.

In this way, Du Xu spent a quarter of an hour rubbing a backward document with a spell, and then used his true qi to make his face pale, and he was given more than a decade of vacation.

Poor Xiaoying and them, I don't know how much effort it will take to sort out the three-story library and tens of millions of volumes of books.

Of course, Du Xu is not so insidious, he left clues in the library, if Xiao Ying carefully packed up the collection of books, and strictly followed the "Outline of Library Collection Classification" he wrote, he would find six books of cultivation hidden in the library, especially the most secret "Shouren Sutra", Du Xu hid a spell, only Xiao Ying can discover this scripture.

Once discovered, the scriptures will turn into golden light and disappear into Xiao Ying's eyebrows, and as Xiao Ying's cultivation grows, the content of the "Shou Ren Sutra" and the cultivation knowledge entered by Du Xu will be slowly unsealed.

"Xiaoying, the teacher can only help you get here. ”

Du Xu looked like he was going to die or live, was supported by two villagers, and returned to his residence, Mu Rongsheng said to him excitedly with tears in his eyes: "Mr. Du, you have a good rest, I know that you like to be quiet, and you will not let that group of little monkeys disturb you." You can rest in the house in peace, and I will discipline the monkeys, and I will not let you worry about them. ”

"Sir, you rest here in peace, every day's meal, I have people delivered to the door, you don't like to disturb, if there is any request, just shake the brass bell at the door, they will hear it, and they will come. ”

Du Xu nodded weakly.

The old tree spirit gave a few commands, and as everyone withdrew, he specially brought the gate before leaving.

The weak Du Xu was lying on the bed, and his divine sense felt that the old tree spirit and the villagers had gone away, and immediately jumped up vigorously, and his true qi ran a few laps, and the paleness on his face, his withering spirit, and his weak physical strength all disappeared.

Now he has a ruddy complexion and is in good spirits, and he is healthier than the big and small monsters in the demon village.

As soon as the Kunlun Mirror in the sea of knowledge flashed, Du Xu disappeared into the room, and the sudden disappearance of existence caused a change in the airflow in the room, blowing a small whirlwind, and rolling the room into chaos.

Entering the small world in the Kunlun mirror, you will be greeted by the vast world, the splendid mountains and rivers, the space is about a hundred miles square, and the most central vast fields are full of colorful plants, a hundred flowers compete for beauty, and the green trees are shady.

Surrounding the periphery of the plain is the misty mountain peak, surrounded by mist, faintly see the ancient trees on the peak, the strong vines are entangled, Du Xu once wanted to explore, but it seems to be blocked by a mysterious force, can not leave this hundred miles of plain.

The aura in the small world of Kunlun Mirror is abundant, but it is a pity that the laws of heaven and earth are not complete, so Du Xu does not cultivate here, what a comprehensive cultivation of the West Kunlun Dao Sutra, and the harm of incomplete laws, how could Du Xu not know?

He has been trying to weaken the existence of this heaven and earth, and at first it was only used as a storage magic weapon, storing some things, including some materials brought by the modern earth, some special products collected in this world, and luggage, which were scattered on a boulder in the plain.

Later, he searched for some medicinal seeds from Li San, and opened up a medicinal field here, allowing the medicinal materials to grow freely. In general, this small world actually didn't bring him much benefit, and it didn't help him much.

Perhaps it could become a medicinal herb source and provide him with some resources for his cultivation.

Because of the useless reason, Du Xu has never built this world well, anyway, the law is broken, and there is no weather, such as wind, rain, thunder and lightning, Du Xu has not even built a house.

Now if you want to refine magic weapons, you can only find a flat place and use spells to process a vacant land and use it as a place for refining weapons.

The alchemy refining tool is a matter of heaven and earth working together, not something that the monk can solve alone, the release of the elixir and the formation of the prohibition of the magic weapon all require the participation of the laws of heaven and earth, and in this small world where the laws are broken, it is really impossible to do it.

Fortunately, the ban on the wheel of life and death that Du Xu wants to refine has been completed, and now it is only to improve the tire of the magic weapon, connecting the banner and the flag.

Du Xu untied the long black belt on his left wrist, grabbed the lead and danced a few times, the black long belt quickly extended and widened, from a small black cloth belt to a black cloth one foot wide and five feet long.

Black silk, eight-grade spiritual material, feminine texture.

In the past, Du Xu didn't have many spiritual materials in his hands, and he knew very little about materials. In such a remote world as the supernatural world, there are even fewer ancient books involving natural treasures.

In the supernatural world, most of the materials of the "magic weapon" are some spiritual mortals, and only by using mana day and night to improve its quality can the "magic weapon" of this world be reluctantly refined. And those real magic weapons like the black-robed evil cultivators are mostly heirloom treasures handed down from ancient times, and the materials are some extinct heavenly and earthly treasures.

Therefore, Du Xu's cultivation and enlightenment teacher, Uncle Jiu, is also unclear about the division of spiritual materials.

Naturally, Du Xu also ignored these things gorgeously, the content of the West Kunlun Taoist Sutra is huge, all-encompassing, it is precisely because the content is too huge, Du Xu has no time to explore them one by one, and his energy is focused on the fundamental methods of cultivation, and the content of the cultivation methods in the Taoist books he reads is complete and rich, but the part about miscellaneous studies is only a few words, and most of them are still unknown.

It wasn't until Du Xu cultivated the innate divine soul, the soul power was a hundred times stronger, and the calculation power and perception power were infinitely expanded, that he kept in mind the content of the Tao Sutra and classified them one by one.
