This time the knowledge of activating the kryptonite plug-in is neither a spell nor a beast control technique, but a drug formula called 'Alien Worm Ripening Agent'.

"......Ripening agent?

Su Mu raised his eyebrows, had a bad guess, and quickly checked the introduction of this potion.

Although this potion has not yet risen to perfection and has limited control of its efficacy, in the introduction, the sentence "can ripen larvae and shorten the growth and breeding period" is enough to make Su Mu confirm his guess.

He pondered quickly in his heart:

"The bookworms made it mandatory for the students to clean up the bookworms because in the recent period, the bookworms in the library have suddenly flooded, which has caught them off guard and kept them busy. ”

"It stands to reason that the library has been built for so long, and all kinds of moisture-proof and insect-proof means and spells are available, even if there are occasional bookworms, the magic circle and book essence here can be eliminated at the first time, and it is impossible for bookworms to overflow......!

"Maybe the insect plague in the library is not an accident, but man-made! Someone smuggled bookworms into the library and gave them special drugs to shorten the reproduction cycle and strengthen their hiding and adaptability. That's why before, the magic circle and book spirits in the library couldn't find their traces until the insect plague broke out!"

I don't know who did this, but it's not hard to guess the purpose - to destroy the books in the library!

In the library of Qingcheng Mountain Xiuzhen University, in addition to ordinary cultivation books, there are also many precious classics and historical documents! If these books are destroyed, the consequences will be unimaginable.

Although these were just Su Mu's guesses, he felt the need to report them to the school.

I am not afraid of 10,000 in everything, but I am afraid of what happens.

Even if this guess is wrong, it is for the good of the school, and no one will blame him.

What's more, there is also Wen Wubin to protect the calves.

Su Mu looked left and right, and made sure that there was no one around, so he took out his mobile phone, dialed Wen Wubin's phone, and reported the situation in the library, as well as his findings and speculations.

After listening to this, Wen Wubin said: "Your kid is really the material for learning Dan medicine. In the library these days, there are many pill students who have taken over the task of book essence, but you are the only one who has noticed that the bookworm has been drugged!"

"The school has long found out about this?"

"Of course. ”

Wen Wubin didn't hide it from him.

"Originally, this matter is confidential for the time being, but it doesn't matter if you tell the kid, after all, you will definitely not have anything to do with this matter.

At the beginning of the flooding of bookworms in the library, we launched an investigation, and found that all kinds of bookworms in it showed signs of being affected by the medicine, and their growth and fecundity were greatly enhanced.

At present, the school has dispatched professionals to form a special task force to thoroughly investigate the matter, especially to find out where the mutated bookworms and those potions came from! In addition, the precious books and documents in the library have also been transferred to other places for better safekeeping. ”

Qingchengshan Xiuzhen University has Jiaotu and Xiong Da who are responsible for security, and there are also experts and professors such as Wen Wubin, so it is unlikely that the person who took the worm and the medicine sneaked in from the outside.

If you really have that strength, you can just destroy the library, why do you have to do this kind of trick?

The biggest possibility is that either there are spies in the school, or there are people with evil intentions among the people who have visited recently!

It is indeed necessary to investigate clearly and find out the main messenger and participants, otherwise there will be endless troubles!

Since the school had already made arrangements, Su Mu put his mind at ease and did not ask about the progress of the investigation, so as not to embarrass Wen Wubin, so he stopped the topic, and after chatting a few words, he hung up the phone.

Putting away his phone, Su Mu walked over to a bookshelf and summoned the book spirit.

A moment later, a book spirit flew in front of him.

Seeing that the person who summoned was Su Mu, this book spirit showed great enthusiasm: "Oh, dear good friend, it turns out that you are calling me." You haven't been to the library in a while, how are you doing?"

As he spoke, an eye cracked open on the cover of the book.

His eyes looked Su Mu up and down, and it wasn't until he saw the dried corpse of the bookworm in his hand that he showed a hint of satisfaction.

Immediately, the book spirit said: "Thank you for helping us clean up a bookworm, what books do you want to borrow this time?"

Shujing's series of actions were all seen by Su Mu.

He couldn't help but complain secretly: "Are you embarrassed to call me a respected good friend? I came to the library, just like everyone else, I have to do a mandatory task before I can see you, and judging by your reaction just now, if I don't have the body of this bookworm in my hand, I'm afraid you will ignore me, right? Is this the way to treat a respected good friend? Hatui, scum!"

Of course, Su Mu would not be able to say these words, after all, he had to rely on the book spirit to help him find books from the vast sea of books.

He smiled and said, "Dear Shujing, I'm glad to see you again. I came this time to borrow these books: "The Nature of Qi", "Mathematical Methods", "Transformation and Utilization of Reiki", ......"

Su Mu told the books that broke through the method of fishing toads swallowing qi and needed liver one by one.

After listening to the book, he immediately recited the mantra, and saw a book, like a butterfly, flying out of the bookshelves and coming to Su Mu.

After checking that everything was correct, Su Mu put all these books into the space bracelet and put them away, and he was about to leave.

Unexpectedly, the book spirit opened his mouth to keep it.

"Please wait a minute, our dear good friend!"

"What, do you want my help?"

Su Mu stopped and turned around.

Shujing said continuously: "Yes, yes, we have a question and want to ask you. ”

Su Mu said: "It's my honor, let's say, what's the problem?"

"That's right, since the library has been plagued with bookworms, we've released relevant tasks. At first, there was no one to take this task, and we had no choice but to set it as a time-limited task that must be completed to enter the library. Now, the amount of tasks has gone up, but all the students who did this task were not satisfied, and some people complained to the school, which made us very painful. ”

"We don't understand, it's all the same task, why do we publish the task, the students are not satisfied, and they have to complain? Is it something we did wrong?"

Shujing looked at Su Mu, with a look of 'we are very wronged', obviously he really didn't know what they did wrong.

Su Mu sighed: "You guys did something wrong. Not only did it go wrong, but it was very wrong!"
