Qianji Sect, the formation of the great sect, although the strength of the martial arts is not high, but with a hand of extremely high formation attainments in the divine domain has also made a reputation, it is rumored that the divine domain was separated from the five continents continent, covering the eyes and ears of the heavenly Dao could not succeed, it was the ancestor of the Thousand Machines Sect who was willing to use his own life as the eye, which really completed this masterpiece.

In the Divine Domain, almost no one dares to be an enemy of the Thousand Machines Sect, because if they casually put a formation on your territory, it is enough to make the other party's disciples scramble, and if they want to sleep in their sect, it is even more fantastical, there are formations almost everywhere in the sect, like a copper wall, and if you don't pay attention to it, you will die in Huangquan.

At this time, a young man wearing a jade crown walked out of the Dawangshan Library and went straight to the storefront of the Thousand Machines Sect.

"Childe, are you back?

"What's going on? What's in the library?"

As soon as he reached the door, two of his men immediately ran over and asked curiously.

The three of them walked and walked, although they seemed to be chatting casually, but if you look closely, you will find that their steps are exactly the same, as if following some kind of rhythm, walking into the depths, their figures faintly begin to blur, and finally seem to be hidden by smoke, completely disappearing.

Going to the deepest part, the interior layout is completely different from what is revealed to the world.

"Dad, mother, you haven't slept yet......" The boy stuck out his tongue and whispered.

"You volunteered to investigate the situation in the bookstore, and what did you see all day?" The middle-aged man frowned slightly, and his voice was dissatisfied, "I've been idle all day long, not doing my job, look what you look like?!"

"Ridiculous!" the middle-aged man was so angry that his hair stood on end, and his face turned red, "It's ridiculous! You unfilial son, see if I don't break your mouth today!"

He trembled and walked up, apparently unable to control himself.

"Master, you are dissipated, Han'er didn't mean to. The woman on the side hurriedly stretched out her hand to hold and comfort.

"Whether it's intentional or not, you must slap your mouth! My thousand-year-old ancestral business, can he slander and insult it?!" The more he spoke, the more angry he became, staring at the young man with bloodshot eyes.

"Dad, I'm telling the truth, there is a numerical algorithm recorded in the library, called Arabic numerals, which is simple and easy to understand, and much more convenient than our hour and direction, and what kind of messy calculations are made!" the boy continued.

"I'm ...... today. Scrap you!" The middle-aged man almost blew up on the spot, "What a bullshit number algorithm, it's just bullshit!"

"Qiankun Xun Zhenkan Ligendui, these directions are obscure, who remembers, it contains all kinds of changes, but if you use numbers instead, use numbers
