Behind the whirlpool is a wonderful world.

Su Qi was shrouded in boundless clouds and mist, he sat in a comfortable circle chair, there was a huge mahogany square table in front of him, which was one zhang long and wide, the table was empty and very smooth, only Su Qi's hand was placed in a palm-sized gold wire copper frame incense box, with a finger-length green incense inserted on it, there was an inkstone next to the incense box, which was soaked in a pool of spiritual liquid, and there was a bamboo pen holder next to the inkstone, and only a pen was placed on it.

The white jade hollow thin tube, with aura inside, the black hair is soft and soft, flashing with a faint aura, and the pen barrel is engraved with four words, like a cloud flawless.

This is a very high-quality spiritual pen.

A little red suddenly appeared on the green incense, I don't know who lit it in the air, the red light flashed a few times, and there was a rising aroma, the taste was mellow, with a hint of sweetness.

A line of words appeared on the table, lingered for a moment, and then faded into the mahogany.

Please complete five questions before the incense ends.

"Before the incense is exhausted...... Su Qi was stunned for a moment, remembering the purpose of this trial, "Is it a formation?"

The spiritual light on the mahogany table flickered, starting from the center, and suddenly a stripe of black lines extended out, and in just a moment, a complex circular formation was formed on the mahogany table, about one-third the size of the table.

However, it is obvious that this formation is incomplete, with four blanks on each side.

"This is ......" Su Qi held his breath, his eyes shrank, and he became slightly nervous.

Although he had never seen this kind of formation, he could already tell from its general structure that it was a formation used for sealing.

"Do you want me to complete it?"

Su Qi smiled, this kind of formation question is still very common in the human race, every formation master will go through such a process when learning, first start by learning the drawing method of the formation, trace it one by one, and then spend a lot of time to memorize all the common formations, and finally it must be able to draw from beginning to end without stopping or hesitating, the time spent on this step varies from person to person, it may take half a year for those with good talent, and it may even take several years for those with poor talent.

But this is just the beginning for the formation master.

After that, you have to memorize a large number of forming formations, from small formations with only a few formations to medium-sized formations containing hundreds of formations, at least more than fifty kinds of formations must be memorized, and then you have to try to draw formations by hand, which is a process that requires practice to make perfect, on the rune paper, on the wall, on the ground, on the magic weapon, in each different location, the skills of drawing the formation are slightly different, and mastering them proficiently is the beginning of a formation master's maturity.

After a long period of study and practice, the formation master also has to spend time to constantly read and study the formations left by his predecessors, these formations may be strange, some may be infinitely powerful, even the half emperor will be frightened when he sees it, and some may seem useless, and can only do such trivial things as removing water and keeping dry, but a qualified formation master can still find what he wants in it, and he can also accumulate a lot of experience, after all, for the formation master, adapting measures to local conditions is the king.

Therefore, it takes far more time and energy to train a formation master than cultivating a monk of the same level, and because of this, the formation master has become a fragrant bait, no matter when and where, a powerful sect will open its doors to the formation master.

Su Qi began to dabble in formations when he was in Qishan, although he couldn't practice at that time, he read a lot of formation books, not only knew the formation theory well, but also studied thousands of formations.

This kind of formation problem book is often sold in the Eastern Wilderness, the price is not cheap, an ordinary monk may need to save a long time to buy one, there will be forty or fifty questions in the book, and there are even hundreds of questions, from completing the formation, deconstructing the formation to drawing the opposite formation, the question type is strange, there is everything, thanks to the old man's collection of books, Su Qi has never lacked such books at hand, he also likes to solve these formation problems, for him, this makes him get back a little bit of the happiness of secretly doing Sudoku in the classroom in the past.

He picked up his pen and quickly glanced at the formations on the table.

The key to completing the formation is to understand the role of this formation, and at the same time, to be familiar with the common formations, so that you can quickly determine what is missing in the blank part.

Lifting the pen, dipping it in ink, and putting down the pen, Su Qi only thought for a while, then quickly put down the pen, and quickly drew on the table.

As he remembered, it was a limited-time game.

After the last stroke, the formation on the table burst into flames, burning quickly from the center, and in just a few breaths, the formation had already burned out, leaving an empty and smooth mahogany tabletop.

Su Qi relaxed slightly, which showed that the solution he had just made was right.

But soon, a second formation appeared on the table.

Same as just now, it is also a completion formation problem, but there are as many as eight blank spaces, which is twice as much as the first one, and the function of the formation is completely different, this is a magic circle that gathers spiritual energy, but it is much more complex than the ordinary spirit gathering array, and the efficiency is also heaven and earth.

Su Qi had never seen this kind of formation.

Is this the spirit gathering formation commonly used by the ancestors of the Terrans? It seems to be better than the current use of the Terrans.

Su Qi bit the pen and pondered for a moment, figuring out the structure of this formation, and then put down his pen while secretly thinking that maybe this trial could gain more than he imagined.

The green incense burned little by little, the curved aroma rose to Su Qi's ears, the surrounding fragrance was very refreshing, Su Qi's attention was also concentrated like never before, as he continued to solve the problem, the formation questions that appeared on the table became more and more difficult, and his thinking time continued to increase, and even on his forehead, sweat began to condense.

In the third question, sixteen places are missing.

In the fourth question, thirty-two places are missing.

It's a lot of work.

After solving the fourth question, Su Qi put down the pen, rubbed his eyebrows, and glanced at the green fragrance beside him, it still had half of its length left, and there was only one question left in front of him.

Time should be enough.

The fifth question was emerging, and the pattern quickly extended to the edge of the table, and it was visible to the naked eye, it was more complex than the previous ones, and it had already taken up the entire table.

And the blank space ......

Su Qi glanced at it and was stunned.

There are 128 blanks!

Almost half of the formations are missing, and the difficulty of making up for it has risen sharply, even if there is still half the time, Su Qi no longer dares to pack the ticket, and it will definitely be completed.

"I knew it wasn't that simple. ”

Su Qi sighed, biting the pen hard, the white jade in his mouth was cold, completely different from the smoky aroma, he stared at the formation in front of him, as if there was nothing else in this world.
