I fought back after reselling my engagement

This is not something that only dragons, snakes and pythons can refine. According to legend, the races that can refine dragon balls are all powerful and extremely talented.

"How can I refine a dragon ball by myself?"

"You don't feel the blood of the divine dragon in your body. I wonder where you are from? As far as I know, there has never been a divine race in this world."

She has the blood of a divine dragon, so she refined dragon balls.

Su Zhen held the bead and used his spiritual sense to detect it. It was a chaos inside. "What should I do now? The space inside is a chaos."

"Once the Nascent Soul is refined, the space can be opened. During this period of time, you can continue to comprehend the power of time."

She had experience and insights in understanding the power of time, and Xueheng taught her in detail.

After hearing this, Su Zhen continued to practice.

After completing his comprehension, Su Zhen entered the training platform and practiced time magic within the platform's barrier. A time spell was a small ball that appeared in a one-to-two ratio, meaning that one day outside was equivalent to two days inside the ball.

She kept practicing, and used the time spell to create time balls, from one to two, to one to four, one to eight, one to sixteen...

Xue Heng looked at the girl who was practicing in the bonsai on the practice platform. It took her three hundred years to achieve minor success in her practice, and three thousand years to achieve major success.

Under the time barrier, it took her only ten years to comprehend the law of time, and another thirty years to improve the ratio from 1:2 to 1:32. One day outside was equivalent to one month inside the space. When she improved her ratio to 1:108, it took her a long time to advance.

Xue Heng was extremely surprised. The other party only took 10% of her time to reach a level that she could not reach back then. She took 300 years to reach 164 and could not make any further progress.

"Congratulations, fairy, you succeeded!"

"Thank you for your guidance in the future."

Su Zhen clasped his fists and bowed. His Nascent Soul had already refined the dragon ball, and there was a space of three acres inside.

Her eyes lit up, and she cast time magic on the dragon ball over and over again. When the time magic was successful, a time barrier would be formed on the ground, and the thin film formed by the time barrier would wrap around the dragon ball.

It worked!

She brought in four bonsais. Once she entered the space, the three rooms were transformed into real size. The alchemy room, instrument room, talisman room, and training platform were still in the shape of bonsais. She wanted to build a pavilion later, and the training platform could be placed on the central table of the pavilion.

With a change of mind, she took out the book of "Array Techniques of Dongyuan Continent" from the mermaid's golden bead, entered the Xueheng Hall to look through the book, and studied the array plates and flags she had purchased.

Xue Heng asked, "You want to learn the art of formation?"

"Yes, I need to deal with Feng Ji. He hides too deep, so I need to use formation techniques."

"To deal with the spirit, there is the Demon-Slaying Formation, but this formation is too murderous. We can use the Demon-Trapping Formation."

"He is a spirit body, can he be trapped by the demon trapping formation?"

"Although he is an immortal, if he loses his physical body, his magic power will be greatly reduced. Only a third-grade demon-trapping formation is needed to trap his soul for several days. To trap him completely, a fifth-grade demon-trapping formation is required."

There are dozens of formations, and each one starts from the first grade. Ordinary formation masters will choose three types of formations: defense, attack, and guard, and pick one or two of each to study in depth.

"I don't understand the art of formations, but I've heard of several formation masters discussing it. There are four types of formations: defense, attack, protection, and tool. The Soul Gathering Formation is a tool formation, the defense is the Solid As Hard As A Rock, and the attack is the Wolf Killing Formation..."

She explained these formations in detail. She didn't understand them, but she had lived long enough to understand more than others.

“If a fairy wants to learn formations, she cannot learn all of them. She should pick two of each. But I heard that the most advanced formation in the world is the Nine Revolutions Heaven and Earth Formation. This painting has formations from the first to the tenth level, and the fourth-level fairy formations, but only the first to fifth levels are handed down in the world. This formation is incomplete, and in the future, formation masters will need to find the rules and deduce it by themselves.

There are several formations in the world, but only the Nine Revolutions Heaven and Earth Formation is all-encompassing, and can be used for attack, defense, and trapping. It can be called a divine formation. But even a formation immortal cannot deduce the appearance of a low-grade immortal formation like this formation, but the formation immortals who can deduce a tenth-grade formation are all formation immortals who have entered the Tao through formations. "

Su Zhen asked: "Senior, in other words, this formation is the highest level formation."

"My west side hall is my study. Although I don't understand formations, I have collected dozens of formation diagrams. When I listened to the formation immortals' discussions, I specially collected books and formation diagrams on this formation. You can find them for reference and study."

Su Zhen asked: "Senior, among the four arts of cultivators, which one of the alchemy, weapons, talismans and formations are you proficient in?"

"Talisman."

In the courtyard, spiritual fruits, fairy fruits, spiritual flowers and fairy flowers are planted, but the spiritual herbs and fairy herbs are all planted according to one's own preferences.

Feng Ji's mustard bead space is full of medicinal herbs, which means that he was an alchemist back then. Among the books he left behind, those on alchemy and cultivation are the most popular, and other books are collected just for the sake of collecting.

He didn't seem to be a book lover. Apart from a book called "Encyclopedia of Magic" and a book called "Alchemy", which had some marks and signs of being read, he had never opened any other books.

"Senior, how long has it been outside?"

"About one day, I cast a double-layer time spell on you. More than forty years have passed here."

"Thank you, senior."

This is great. She studied in there for more than forty years, but only one day passed outside.

Su Zhen put down "Array Art of Dongyuan Continent" and went to the study in the West Hall. Compared with Feng Ji, Xue Heng was definitely a person who loved reading and collecting books. There were dozens of bookshelves in the West Hall of more than 100 square meters, which were classified according to level, spiritual roots, and categories. There were all kinds of books of the three grades: immortal grade, heaven grade, and earth grade. There were all kinds of elixirs, weapons, talismans, and arrays, as well as Taoist, Buddhist, demon, spiritual, martial, and physical cultivation.

She stood in front of the books on formation techniques. On the middle layer was a sticker titled "Nine Revolutions of the Universe". She took all the books on that layer away, returned to the main hall, summoned the training platform, entered it, sat there and first read the introduction to formation techniques, then looked at the formation diagram of the first-grade Nine Revolutions of the Universe, took the formation flags she had bought and set up the formation. After setting up the formation, she would break the formation and attack. After she broke it, she would repair it. After the repair was completed, she returned to the original place, checked the instructions for the second-grade Nine Revolutions of the Universe, the books on the experience of the formation immortals, and then set up the second-grade Nine Revolutions of the Universe.

Xue Heng looked at the people practicing the bonsai. Because time passed slowly outside, it was like fast-forward for the people inside. Often they would finish what they had just sat down to check.

Su Zhen summoned the weapon room from his Dragon Ball Space, shrunk it into the size of a bonsai, placed it in the hall, entered the weapon room, prepared materials, and began refining weapons.

Xue Heng could see her busy work through the glass of the equipment room. In just three moments, she had refined several formation flags.

Su Zhen came out of the equipment room and entered the training platform again, and began to lay out the third level...

It was too fast. It took a first-class person one month to learn how to set up the formation, two months to break it, and another three months to restore it. In total, it took half a year to learn everything.

The second-grade formation takes one year to complete; the third-grade formation takes three years to complete; and the fourth-grade formation takes six years.

Xue Heng thought it would take her twelve years to learn the fifth-grade formation, but it only took her eight years.

The sixth-grade formation needed to be deduced, so she looked for patterns between the first and second grades. She took a pen and some paper to do the calculations. It took her a month to find the patterns and deduce the third-grade formation. She compared the two sheets and found that there was only a slight difference between the beginning and the end of the third-grade formation. She also drew it out. When she did it the second time, the result was exactly the same as her first time.
