Lin Si's idea is very beautiful, but it ignores a practical problem.

That is, so many trial rooms are guarded, why is there no one near this one.

The trials in the trial room are driven by the formation, and what needs to be consumed is the spiritual power in the formation, if anyone can enter casually, then how can the academy afford this kind of consumption.

On the door, he didn't see anything like handles, latches, or locks.

He was going to push the door straight in, and pushing the door was a very simple action, just reach forward. He made this movement naturally, and then the door naturally did not move.

He touched his chin, it was a bit too cruel, not to mention that if he made a fuss, he would immediately attract others. Even if there is no one, it seems that such an unwarranted destruction of school facilities is unjustifiable......

Standing in front of the black stone door, Lin Si fell into deep thought, and finally found an unguarded trial room, so he was naturally unwilling to give up, so he walked around the door and took a closer look.

Soon, he slapped his forehead and sighed to himself, there was a dark green square pattern on the wall next to the door frame of this door, the pattern was not large, only the size of a palm.

There was a stripe in the pattern, and he looked closely, and saw that it seemed to be similar to the one on the top of the instrument that the Administrator used to check his ID card credits.

Do you want to put the ID card on it?

Maybe this doesn't cost any credits at all! He took out his identity card and put it on the dark green square, which lit up and then went out.

Lin Si pushed the door again, and then disappointed again......

He finally understood that this dark green square was equivalent to a fixed administrator, and he couldn't get in if he didn't have enough credits.

He couldn't help but want to explode, how can this school have credits everywhere!

But he's not one to give up so easily, it's still morning, and he has time to try.

He approached the dark green square, carefully looked at the pattern inside, and after looking at it for a long time, except for dizziness, he could see that this should be a small detection formation.

Although Lin Si had never been in contact with the formation, he had studied in the city of the academy for a few days and read a lot of books on cultivation, and he had heard of such things as formations, but he had not learned them.

If you can directly break this formation, then you don't need to take credits and go in directly?

As soon as this thought appeared in his mind, he could no longer linger, and during this time he was really overwhelmed by the so-called credits.

Lin Si didn't know that if he was known by others, he would definitely laugh off his big teeth, he would think of directly breaking the formation at the door and entering, just because he didn't understand the formation at all, and the ignorant were fearless.

It's not easy to break the formation, since this detection formation is placed here without care, it is recognized that the students can't break it, and they can only rely on the credits of the identity card to get in.

Since the day this trial room was built, no one has been able to break into it without an identity tag.

Lin Si didn't think that he was not talented, but that was reflected in his cultivation. As for the formation, he was not so arrogant that he felt that he could directly break through this formation that made other students, including the formation students, be turned away by just reading a few formation books.

But how do you know if you don't try it? At least it's tempting to get in without credits in the future, isn't it?

He quickly retreated, leaving the Trial Hall and heading straight for the library.

Although the formation also involves cultivation and spiritual power, there are still some popular formation knowledge on the mainland on the second floor of the library.

Lin Si even forgot to go to lunch, sitting on the ground under the bookshelf with a book, he watched it very attentively, and the introduction of the basic formation was gradually memorized by him.

Putting down the book in his hand and breathing a sigh of relief, he rubbed his somewhat sour eyes and found that it was dark again outside. From morning to evening, he memorized no less than four or five formation books. If someone else knows about this "feat", it must be unbelievable.

He didn't seek to understand the medical books when he memorized them, but he really understood these formation books, although the depiction of the formation required spiritual power, but maybe it was related to cultivation, he was born with talent and interest in this kind of thing.

According to the book, the so-called formations are composed of three aspects, the entrance of the formation, the line of the formation, and the nodes of the formation.

The entrance of the formation is the place where the external spiritual power is accessed, and it is the source that supports the operation of the formation, if there is no source of power, then the formation is just a bunch of complex pictures.

The line of the formation is the route of the arcane power within the formation, and the node is the transit place of the transformation of the formation line. Because of the different lines and nodes, the formation can become a formation with different effects.

This is also why the formation needs a formation map, because the line is too mysterious, and even some large formations still need a formation disk.

Just like an attribute long sword used by a Transit Realm cultivator, the sword body depicts a formation that amplifies the effect of wind attributes, so ordinary people use this sword, at most, because the material is better than fine iron, it is more tough and sharp, and they can't drive the formation of the sword body.

And only when it falls into the hands of a wind cultivator, the wind amplification array carved on the sword body can be activated by the wind attribute spiritual power infused by the cultivator, thus enhancing the wind attribute power that is finally exerted.

So what kind of formation should be used for a sword of this kind of strength that suits him? Lin Si thought for a moment, as if there was no one who had ever cultivated the power of sealing, so there was no such formation at all.

But now I am not here to draw the formation, but to break the formation.

There are several ways to break the formation, one is to break it by brute force and directly destroy the formation. But most of the formations were already integrated and indestructible. Moreover, Lin Si didn't dare to forcibly destroy the testing formation in the trial hall, once he was discovered, he couldn't afford to pay for it.

The second is to remove the power source of the formation, for most formations, removing the power source is a dead thing, and there is no threat.

But the detection array in the Trial Hall was actually equivalent to a lock, and it was itself a dead thing that had not been activated. Only when the points on the ID card meet the required requirements can the power source be activated to make the formation work, thus opening the door lock.

Instead of destroying his power source, Lin Si had to find a way to activate this formation. Let the formation treat him as a student with enough credits, and directly open the formation to let him in.

But that formation obviously has an identification system, otherwise it would not be possible to determine the number of credits of the identity card. Where is it so easy to rush casually?

He scratched at his hair in distress, not knowing where to start.

Seeing that it was not early, anyway, there was still time the next day, so he decided to go back and discuss it with Mu Zheping.

......

At home in the small bungalow, Lin Si was feeding the children while introducing today's events to Mu Zheping.

"Haven't you given up yet?" Mu Zheping smiled, he seemed to be very dismissive of the school's trials.

"Now it's not a question of giving up or not giving up, but if we find a way to get in, it means that the places that need credits to enter in the future, as long as there is no one to guard, we can enter directly! How difficult it is to get credits You should also know that the credits of both of us are currently zero!" Lin Si analyzed without raising his head while feeding the child a small bite of food with a spoon.

"What you said is very reasonable, but why do you think that the detection formation that so many people can't open, the two of us can open it!" Mu Zhe showed a mocking look and said slowly: "That detection array is placed there and no one is guarded, which means that no one can directly break through without credits, including the students and even teachers of the formation department!"

"That's right, I know!" Lin Si didn't care at all about his words, he had already thought of these things.

"But what we're using isn't spiritual power, it's the power of imprints!, I think, this kind of power may have a surprise effect on breaking the formation!" he chuckled at the corner of his mouth.

"Why do you think that?" Mu Zheping didn't know where his confidence came from.

"First, the pattern of our Heavenly Seal itself is more complex than those so-called formations, and it may be a formation itself!"

"Second, you should be able to experience that the power of the seal is more advanced than the spiritual power, right? Just like my seal power can be endorsed, your seal power can increase the power of thousands of catties, and the spiritual power does not have this special effect at all. Moreover, we can fight hard with the spiritual power cultivators in the late stage of the transition realm just by infusing the power of the middle stage of the speculum, no matter the strength and speed, the reaction is not weaker than the other party, do you think the spiritual power of the same level can do it?"

"Third, I forgot to tell you that I have been able to excite the SCP through the body!"

After Lin Si said these words, he waited for Mu Zheping's shocked eyes.

He was not disappointed, and when he heard him say that he had been able to stimulate the SCP penetration, Mu Zheping's face really changed.

"How did you do it, and when did you do it?" he couldn't stay calm anymore, because he was also a seal-power cultivator, and this kind of thing had something to do with himself.

Lin Siyang was proud: "Hehe, I can't think of it! The pattern of my second layer of heavenly seal is actually very early!"

"Say it quickly! Sell a hairy pass!" Mu Zheping said impatiently.

"Ahem, walking on the road this morning, I had an idea to think of a way to run SCP, a place I had never thought of before!"

"What is it?"

"You have also guessed that if we want to come out of the body, what we need is that the SCP force is strong enough to a certain extent, maybe it can be stimulated, in fact, yes!"

"But our SCP strength is simply not enough!"

"That's right, but our seal power can flow through each other in the body, so why don't we concentrate all five seal forces into our right hand, isn't that strong enough?"

Mu Zhe looked suddenly, this place was just that he hadn't thought about it, and in addition, it would take a few days for him to flow through the whole body, so he always thought that it was still very early for the body to be transmitted to the body.

"But in the battle, if you concentrate all the five forces to one point, then there will be no imprint power in the legs and torso, which will affect your speed and defense ability! He hesitated.

"That's right, but you're also a good fighter, and you should know that sometimes you need to concentrate a little bit to break through the opponent's defenses, and when you should be desperate, the more powerful the better, and it's worth sacrificing a little speed. What's more, we don't have to fight now, the power of the seal comes out through the body, and there is hope for unlocking that formation!" Lin Si said disapprerovingly.

Mu Zheping naturally understands this truth, and Lin Si's discovery allows the two of them to stimulate the power of printing in advance, which is naturally good news. He's just used to thinking about all aspects of things, good or bad, and trying to be as thoughtful as possible.

"What if you inspire me to take a look?"

"Ahem!" At the mention of this, Lin Si seemed a little embarrassed.

"What's wrong?"

"See for yourself!" Lin Si put the child into Mu Zheping's arms, stood up, and ran the exercises. The five imprints converged in his palm.

The wide palm seemed to have countless openings, and a blue light instantly revealed and wrapped the palm.

The blue light is an inch thick, but it's only an inch......

Mu Zheping held the child and watched intently, for a long time, he asked suspiciously: "What is the use of only stimulating this Cheng dù?
