Tianyu Alchemy Lord

And such a large circle formation definitely requires an energy source to continue to operate.

The formation master discovered that the energy source of this formation turned out to be the evil spirit of the sinful place!

The energy source of this formation is actually connected to the evil aura in the Sinful Land. In other words, as long as there is evil aura in the Sinful Land, this formation can continue to operate for a day.

On the contrary, there is only one way to turn off this formation, and that is to make the sinful place free of evil spirits. As long as the evil spirit disappears, the formation will naturally become ineffective.

That way, everyone who is imprisoned in the land of sin can be freed again.

So, from that moment on, the formation master was dedicated to finding the source of the evil aura in the sinful place. It's a pity that he spent his whole life without achieving anything, and he could only die in depression.

And this "Hundred Formations Heavenly Book" is the summary he made by writing down his life's hard work before he died.

The content of this "Hundred Formations Heavenly Book" not only contains the essence of some formations that he has summarized throughout his life, but also various formations that he has learned from ancient classics and previous works.

These formations are of extremely high grade, and only a few people can master them.

But in the "Hundred Formations Heavenly Book", the principles and arrangement methods of these formations are clearly written and explained in simple terms. Anyone with a certain foundation in formations can try to understand it.

The more Su Chen read through the "Hundred Formations Heavenly Book", the more surprised he became.

There are exactly one hundred formations recorded in the "Hundred Formations Heavenly Book", no more, no less. As long as he can thoroughly understand this "Book of One Hundred Formations", he can master these one hundred formations.

In addition, the "Book of One Hundred Formations" contains the formation master's own summary of the formation experience. Su Chen believed that if he could thoroughly digest this book, his attainments in formations would surely reach a new level. Enter a new stage.

Although Su Chen also studied formations in his previous life, his research was more on the basic principles of some formations, and he didn't cover much about actual combat.

And this "Hundred Formations Heavenly Book" is more about the actual combat of formations and how to arrange formations in actual combat. In this way, it just made up for the shortcomings of Su Chen's formation in his previous life.

Su Chen turned his attention back to the preface. At the end of the preface, the formation master wrote a sentence.

"My lifelong wish is to be able to crack the formations of the Sinful Land and free all the prisoners in the Sinful Land. Now it is no longer possible. If anyone who comes after gets the "Hundred Formations Heavenly Book" written with my whole life, please remember my If you have the ability, your wish will be fulfilled for me. Remember, remember..."

In Su Chen's eyes, it seemed as if an old man with white eyebrows appeared in front of him, giving instructions earnestly.

At the end of the preface, there is the signature of the formation master: Guo Yue.

It turns out that this formation master, one of the three founding ancestors of Sinful Land, is named Guo Yue.

"Senior Guo Yue, since I have inherited your formation, I will definitely keep your wish in mind and work hard to find opportunities to fulfill it."

Su Chen clasped his hands together and said to the "Hundred Formations Heavenly Book".

Guo Yue's wish is to free all the prisoners in the Sinful Land. This should be because he is also a prisoner in the Sinful Land, so his perspective on the problem will naturally be biased towards the warriors in the Sinful Land.

However, from Su Chen's point of view, there is nothing wrong with this. Su Chen doesn't know how to judge morally. What's more, in Su Chen's opinion, locking people up in a sinful place for generations and even giving birth to children with the marks of prisoners is too severe a punishment. Most people simply cannot afford such a severe punishment.

It is actually not impossible to fulfill Guo Yue's wish. Because Su Chen had already found the source of the evil aura in the sinful place.

The source of the evil aura in the Sinful Land is the soul of the true dragon. Nowadays, the True Dragon Soul has been exhausted, so in fact, even if Su Chen does nothing, the formation in the Sinful Land will gradually become ineffective after decades or more than a hundred years.

However, if you want to disable it immediately, you need to do something.

At the moment, Su Chen put away his thoughts for the time being and began to study the main text of "The Book of One Hundred Formations" instead of thinking about it.

Soon, Su Chen was immersed in the world of formations.

When Su Chen raised his head again, he didn't know how long had passed.

"The mystery of this formation method is almost as good as the alchemy method."

Su Chen took a long breath. This feeling of swimming in the ocean of knowledge made him feel fulfilled.

At this moment, Su Chen glanced at the book in his hand with unfulfilled interest. Although he didn't see enough, he knew that he was still in the process of "selection" and could not waste any more time.

Although the appearance of the man in blue made Su Chen realize that there was something fishy about this so-called "selection", before knowing the truth, Su Chen still had to act according to the rules of the selection game.

At that moment, Su Chen glanced at the man in blue and saw that the man in blue was still unconscious, so Su Chen stepped out of the mustard space.

When we arrived outside, it was already early in the morning. Only then did Su Chen realize that he had been reading in the Mustard Seed Space all night.

At the moment, Su Chen looked around, chose a direction, and started on his way.
