It is also very simple to have this conclusion, since it will appear here, and it can help repair the formation, the only thing Su Yu can think of is the drawing of the formation.

Direct learning means that they don't need to have a particularly advanced knowledge of the formation, as long as they know a little bit about the skin, they can directly repair the formation after learning.

And the Dark Stone is the raw material for restoration.

As for this fragment, Su Yu personally thinks that it should have nothing to do with the formation, because it is a fragment, plus it is dropped by the core statue, so it is reasonable to infer that it should have three fragments, and after collecting all three fragments, it can be combined into a complete prop.

The drawings are complete and can be studied directly, so there is basically no such thing as having to find a third drawing to repair the formation.

As for why there are two drawings...... This is unknown for the time being, but Su Yu feels that as long as he learns, he should know.

"I think these two drawings should be formation drawings, do you know anything about formations in Ning Shi?" Su Yu handed one of the drawings to Ning Shi.

In her opinion, even if Ning Shi has not studied the formation, but she also said just now, she has seen others repair the formation, and repairing the formation is a matter that requires concentration, and it is impossible for the general relationship formation mage to let you watch, so this formation mage should have a good relationship with Ning Shi.

In the case of having a friend who is a formation mage, Ning Shi must know more than ordinary people.

As he guessed, Ning Shi nodded after hearing it: "I understand a little, I'll take a look first." ”

After looking at it for a while, Ning Shi asked Su Yu for another drawing.

"These two drawings are indeed the drawings of a formation, but it is not the formation used by the Black Domain, and I don't know for the time being, in addition, these two drawings are the same." Ning Shi's words were all expected by Su Yu.

Although Ning Shi also said that he was not sure if it was this formation of the Black Domain, the two of them knew in their hearts what the answer was.

"In that case, do you think we should fix the formation first, or solve this statue first?" In Su Yu's opinion, whether it is to repair the formation first or solve the statue first, there is a risk.

If the formation is repaired first, but the statue is not hit later, then they must leave.

Leaving means that progress is reset to the time when the second core statue is killed, which means that they need to repair their formation one more time.

However, since it can repair the formation once, it shouldn't be difficult to repair it again, the focus is on whether the materials are enough, after all, the number of dark stones is limited.

But if you choose to solve the statue first, the risk point lies in the crack, in case the crack gets bigger and bigger, or the black domain explodes directly, then the consequences are needless to say.

"If Lord Su asks my opinion, I personally definitely think that the formation should be repaired first." After all, Ning Shi and Su Yu are not the same kind of people, and they don't know about the dungeon, nor do they know the progress, so they can't take this into account.

However, if the number of dark stones is not considered, Su Yu must also think about repairing the formation first, which will definitely be safer.

"Then let's go and see how the formation is repaired first." Hesitating all the time is not a solution, they have been in this dark place for long enough, and many of Su Yu's decisions must be made as soon as possible, instead of hesitating.

She was going to see how to repair the formation first, and how many dark stones would need to be consumed to repair the formation.

The best case scenario must be that she has enough Dark Stone on hand to repair twice, so that at least one chance is still preserved.

The next situation is that the dark stones in her hands are not enough, but because there are still nine ordinary statues that have not been hit, here are nine dark stones, if it is really not enough, then go and beat the remaining statues.

As for the worst case, it must be that the dark stones provided by the entire dungeon add up, which is only enough to repair the formation once...... But Su Yu felt that this possibility was very low, and the system would not leave the player with any way to survive in most cases.

Not to mention that this is a three-star copy, even a four-star copy is not so.

Anyway, Su Yu decided to take someone to see the situation first, and before that, Su Yu was going to assign the drawings first.

There are two drawings, one is used by Ningshi, and the other is used by Su Yu himself, and the reason does not need to be said.

After learning the drawings, the group returned to the location where they had killed the two core statues.

"These two core statues are the important props that support the formation, so we only need to fill in the missing props in these two positions, and the formation can be restored."

As soon as Ning Shi's words came out, other people who didn't know the existence of the crack were a little puzzled.

"It's not...... We finally demolished the statue, why do we have to restore it now? ”

"yes, didn't you say that this statue would increase the strength of those dark creatures? Aren't the dark creatures going to be stronger after the repair?! ”

……

Questions like these go on and on.

Su Yu didn't explain the matter of the crack, because it was easy to panic, but it was obviously not okay not to explain it at all, so she changed her statement.

"Although we want to destroy the formation, destroying the formation will also affect the formation, and the formation is easy to explode when it is in an unstable state." Although they were all explosions, the formation explosion would sound a little more acceptable than the explosion of the entire black domain.

Even so, there were people who felt scared.

"I see...... No wonder we have to repair the formation, so in this way, won't our previous efforts be in vain? ”

Although they definitely didn't want the formation to explode, they also didn't want the statue they had just destroyed to be restored, and the strength of the dark creatures would be strengthened again......

Su Yu and Ning Shi both knew everyone's concerns, and Ning Shi was more professional, so she explained the problem of repair for everyone.

"Repairing the formation does not necessarily restore the original effect, we only restore the stability of the formation to prevent it from collapsing and exploding, which will not affect the effect of the formation." It was precisely because it would not affect that Su Yu and Ning Shi did not hesitate to repair the formation.

Otherwise, the matter of the crack is solved, and the dark creatures and statues are strengthened again, which is not good news compared to the crack.

"That's ...... so"

"How do you fix the formation? Can we help? ”

In fact, they can't help, after all, they don't learn the drawings, and even if they help, it's a disadvantage.

But that was certainly not the case, Su Yu told some of them to rest, while others were on guard in place to prevent dark creatures from harassing them while they were repairing the formation.

……

……

The repair of the formation was very successful, and it didn't take much time.
