Sitting in Shanhetu's own cave mansion, Cheng Yu did not cultivate, but was studying the runes of the Soul Suppression Tower. During this time, he memorized all the formations mastered by the soul suppression.

Ma's, we won't be alive, we'll carry it down if we're dead, it's all right!

Although he has mastered these formations in his hands now, this is the same as studying in school, he only memorized one answer and couldn't understand the principle, which made Cheng Yu very depressed.

Cheng Yu sat on the fifth floor, and set up a Yuanyang Soul Formation according to his memory, watching the red runes flickering in the air, and the formation on the ground was also glowing with red light, he wondered in his heart, how did so many runes form a formation? How were these runes chosen?

Around the runes that activated the formation, Cheng Yu tried hard to understand the principle, but these runes were constantly rotating and glowing, making Cheng Yu's observation very difficult.

This has almost become a compulsory course for Cheng Yu every day, and he will spend several hours every day studying these things.

Although it was very difficult, Cheng Yu did not give up, he admired this predecessor who built this Soul Suppression Tower, he was able to create such a magical Soul Suppression Tower, this predecessor was definitely a genius with extremely high formation attainments.

However, Cheng Yu only knew a little bit about the formation, and even the jewelry he created for several women only added some simple formations suitable for cultivation, such as the spirit gathering array used to help them gather qi, and the tracking formation used to determine their location.

These formations look very practical, maybe in front of ordinary monks, Cheng Yu is still good, but in front of monks who really understand formations, Cheng Yu's formations are too ordinary, and even some can't be put on the table.

Real formations, everyone, they can trap people of the same level or even higher than their own cultivation just by using the formation! Cheng Yu learned all auxiliary formations, and the really powerful ones are attack and kill formations!

A sealing formation like the Soul Suppression Tower is also a special offensive formation, what about your cultivation level? For Cheng Yu, the cultivation of the Yuan Infant Stage is high, and it is not still sealed by the Soul Suppression Tower.

This is the power of attacking the formation, and you can easily clean up the enemy without spending a single soldier, so do you still need to fight? If you understand a strong defensive formation, then even if you hide at home and sleep, you don't have to worry about the master coming to attack you! With his attack like earth-shattering, I can also sleep soundly in front of the bed.

Therefore, Cheng Yu felt that if he could crack the principle of the formation here, he would definitely be able to become a formation master in the future, and even if Kunlun really hit the sea of clouds, he could not be afraid!

After watching it for a long time, Cheng Yu shook his head and sighed, he still didn't find anything different! Holding a rune in his hand, Cheng Yu had an urge to smash this thing, thinking about what was going on inside!

But this thing is so precious, and I can't bear it! Suddenly, Cheng Yu slapped himself!

I want to know what's inside, do I need to smash this thing? I can't just use my divine sense to probe it!

Thinking of this, Cheng Yu began to use his divine sense to probe in, first his brows were furrowed, and he felt that it was a little blurry inside, but slowly, Cheng Yu's frowning brows suddenly relaxed, and then, his face turned into excitement and joy!

There is really a way in this, and I saw that there was a formation inside, to be exact, an incomplete formation! Cheng Yu was not proficient in the formation, but it didn't mean that he didn't know whether the formation was complete or not.

After his research, the formation in it is indeed an incomplete formation, but unfortunately, Cheng Yu can only see the incompleteness of the formation, and the others do not understand.

Thinking of this, Cheng Yu didn't study it anymore, but withdrew his divine sense, and then grabbed several other red runes that formed the Yuanyang Soul Formation with it, and then probed his divine sense into it one by one.

After careful comparison by Cheng Yu, he finally found that the remnants inside were all remnant formations, but these remnant formations were the same formation, that is to say, the reason why these runes could form this formation was because each rune was equivalent to a part of a complete formation.

Knowing this, Cheng Yu's finally came to the ground, this formation is very complicated, although I know that these are part of a formation, but this is like a jigsaw puzzle, with the fragments of the same picture, but how to put together a complete picture still takes time to explore.

This remnant array is in the rune, but it can't really be like a jigsaw puzzle, one remnant array after another remnant array, Cheng Yu had no choice, and finally went back to his room to find a pen and paper, and then traced on the formation with his divine sense, drawing each remnant array.

This formation is a total of twenty-two runes, each remnant array is very complicated, when Cheng Yu drew all these twelve remnant arrays onto the paper with a pen according to his divine sense, Cheng Yu felt like he had gone through a big battle, because if he used his divine sense to copy the remnant array for a long time, it was really not an easy task.

But now that the remnants are on paper, it's really a jigsaw puzzle. I saw Cheng Yu pouting his ass lying on the bed, carefully comparing the twenty-two remnants, and then carefully piecing them together.

But this thing is far more difficult than Cheng Yu imagined, even if the twenty-two remnant diagrams are placed in front of him, there is no way to put them together into a complete array diagram!

Cheng Yu fought for more than an hour, and he was confused, and then he remembered an important question. Since these runes are arranged in order, aren't the formations in this order also in this order?

Thinking of this, Cheng Yu slipped into the Soul Suppression Tower again, put out this formation again, and then compared the order of this rune, put these pieces of paper in the order of these runes.

"Haha! Lao Tzu finally succeeded!Haha!" Looking at the formation formed by the twenty-two pieces of paper placed together, Cheng Yu finally shouted excitedly!

"Soul Suppression!See? This is the formation diagram of the Yuanyang Soul Formation Formation!" Cheng Yu looked at the formation and shouted.

"What is the use of roaring, what is the use of knowing the formation? Will you use it? Can you put on a new formation now?" The figure of the soul suddenly formed in front of Cheng Yu, and he looked at him with disdain and said.

"Well, it seems to be really like this, but it doesn't matter, I believe in the wisdom of Young Master Ben, it's all a matter of time!" Cheng Yu was stunned, and then said disapprovingly.

Anyway, the research that has been going on for a while has finally found a breakthrough, although these are only cracked with existing formations, but isn't this a good start?

"Huh, isn't this formation the big formation below?" Cheng Yu put the formation on the paper on the ground, which happened to be very similar to the formation that was lit under the twenty-two runes next to him, Cheng Yu picked it up and compared it and said in surprise.

Zhen Soul looked at the formation on the paper, then at the shining formation, and finally looked at Cheng Yu with an idiot-like look.

"What kind of eyes are you?" Cheng Yu was a little embarrassed by the soul suppression.

"This is the result of your research? Such a big formation is in front of you, and you have made so much effort, this is what you call wisdom? Your wisdom is also suitable for taking off your pants and farting!"

"Hmph, you seem to be very powerful, if you are so powerful, why don't you know these things?" Cheng Yu said depressedly.

"As the owner of the Soul Suppression Tower, you should also have the responsibility to understand him, if you want me to sue you all of them, what's the use of asking you to be the master?"

"Okay, okay! I can't talk about you, but then again, aren't all the same big arrays? Isn't it different every time?" Cheng Yu didn't fight with the Zhen Soul, but turned to the main topic.

"Of course this one is different!" said Soul Suppression, of course.

"Damn, do you know this, then why don't you sue me?" Seeing the calm and relaxed appearance of the soul town, Cheng Yu was suddenly angry, this girl really knew about this, and she didn't tell herself.

Zhen Soul didn't speak, just looked at him with disdainful eyes.

"I know, I'm the master of the Soul Suppression Tower!" Cheng Yu pursed his lips and stopped speaking for a while.

It is true that he is the owner of the Soul Suppression Tower, but isn't he also the soul of the Soul Suppression Tower? Doesn't he have the responsibility to fully grasp and understand the Soul Suppression? But Cheng Yu is also lazy to say this, as the saying goes, it is better to ask for others than for yourself.

"I do know this, but what can I do? As you can see now, you activated this formation because you first knew the use of these runes. But what about the other things you don't know? You still can't activate the formation, so naturally you can't know what the formation is displayed?" Zhen Soul put away his disdainful expression, and instead looked at it seriously and said.

"Then I can fight like just now!" Cheng Yu thought for a while and said.

"You're right, this is indeed a method, but it's the stupidest method! The old master also did this, I told you that several of your formations were found by her in her lifetime! Do you think you can find out all these runes in a few lifetimes?

Also, each layer represents the highest number of runes in the formation! This fifth layer means that the formation here will use a maximum of fifty runes, do you think that without any prompting, you can find the exact fifty runes, and then put together the correct formation?"

"What? The formation here will use up to fifty? So, a formation on the ninth layer may use up to ninety?" Cheng Yu said in shock.

Zhen Soul really knows a lot more than him, but this is pressure on him, and it seems that this is also the reason why he is reluctant to sue himself.

"Yes, so this method is okay, but it's not the best way, the reason why I don't sue you is that I hope you can find a better way! I sue you that these formations have been found by generations of masters with their lives, tell me, how many can you find in this life?" said Zhen Soul seriously
