This time, the knowledge that activates the Krypton Gold plug-in is neither a spell nor a beast control technique, but a medicine formula called a ‘Zerg’s Ripening Agent’.

"Ripeness agent? Could it be..."

Su Mu raised his brows and had a bad guess, so he quickly checked the introduction of this medicine.

Although this potion has not yet reached the perfect level of Kryptonium and its efficacy is limited, but in the introduction, the phrase "can ripen larvae and shorten the growth period and reproduction period" is enough to make Su Mu affirm his guess.

He thought quickly in his heart:

"The bookworms made a mandatory task to let the students clean up the bookworms because during the recent period of time, the bookworms in the library have suddenly flooded, making them unprepared and overwhelmed."

"It stands to reason that the library has been built for so long, and all kinds of moisture-proof and insect-proof methods and spells are all available. Even if bookworms occasionally appear, the magic circle and book spirits here can be eliminated in the first time. It is impossible for bookworms to be infested! Perhaps this zerg worm ripening agent can explain some problems..."

"Perhaps the insect plague in the library was not accidental, but man-made! Someone secretly brought bookworms into the library and used special potions for them to shorten the reproduction cycle and strengthen concealment and adaptability. So before, the library The magic circle and the book spirits in there weren’t able to find their tracks until the insect plague broke out!"

Although I don’t know who is the one who made this kind of thing, it’s not hard to guess its purpose-to destroy the library collection!

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Mountain Xiuzhen University, in addition to ordinary practice books, there are also many precious classics and historical documents!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

Although these are only Su Mu's guesses, he felt it necessary to report to the school.

Don't be afraid of ten thousand in everything, just in case.

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

Besides, there is Wenwubin protecting the calf.

Su Mu looked around and made sure that there was no one around, so he took out his cell phone, dialed Wen Wubin's number, and reported the situation at the library, as well as his findings and guesses.

After listening to Wen Wubin, he said: "Your kid is really learning alchemy materials. In the library these days, there are many immortality students who have taken the task of book essence, but I can notice that the bookworm has been killed. Medicine, you are the only one!"

"The school has long discovered this situation?"

"of course."

Wen Wubin did not lie to him.

"Originally, this matter is confidential for the time being, but it doesn't matter if I tell you the kid. After all, you are definitely not related to this matter.

At the beginning of the flood of bookworms in the library, we launched an investigation and found that all kinds of bookworms in the library showed signs of being affected by the medicine. The growth and reproduction ability were greatly enhanced, and there were different degrees of evolution. , Can adapt to the anti-insect circle in the library, and escape the detection and culling of the anti-insect circle, so it can be flooded!

At present, the school has recruited professionals and formed a task force to investigate the matter thoroughly, especially to find out where the mutant bookworms and the medicines came from! In addition, the precious books and documents in the library have also been transferred to other places for better storage. "

Qingcheng Mountain Xiuzhen University has Jiaotu and Xiong Da who are responsible for security work, as well as experts and professors such as Wen Wubin. It is unlikely that the people who put the insects on the medicine came in secretly from the outside.

If you really have the strength, you can destroy the library directly. Why do you want to do such a trick?

The most likely reason is that there is a spy insider in the school, or there is someone who has a bad intention among the people who visited recently!

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

Now that the school had made arrangements, Su Mu let go of his mind and did not follow up on the progress of the investigation, so as not to embarrass Wen Wubin, so he stopped the topic and after a few small chats, he hung up the phone.

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

After a while, a book spirit flew in front of him.

Seeing that the person summoned is Su Mu, this book is very enthusiastic: "Oh, dear friend, it turns out that you are calling me. You haven't been to the library for a while, how are you doing recently?"

While speaking, an eye was cracked on the cover of the book spirit.

He looked up and down Su Mu until he saw the mummy corpse of the bookworm in his hand, showing a trace 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?"

This series of actions by Shu Jing were all seen by Su Mu.

He couldn't help but secretly vomit: "I am so embarrassed to call my esteemed good friend? I come to the library, just like others, I have to do mandatory tasks before I can see you, and seeing your reaction just now, if I don’t have this one in my hand The body of the bookworm, I am afraid you will ignore me? Is this the way to treat a respectful friend? Hatui, scum!"

Of course, Su Mu couldn't 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 am also very happy to see you again. This time I am here, I want to borrow these books: "The Nature of Qi", "Mathematical Methods", "Transformation and Utilization of Reiki" ..."

Su Mu talked about the books that needed the liver to break through the method of fishing toad and swallowing qi.

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 they were correct, Su Mu put all these books into the space bracelet, and was about to leave.

Unexpectedly, the book spirit is still opening up.

"Please wait, our dear friends!"

"Why~lightnovelpub.net~ do you want me to help?"

Su Mu stopped and turned back.

The book Jing continued to say: "Yes, yes, we have a question and want to ask you."

Su Mu said: "This is my honor, let's talk, what's the problem?"

"That's it. Since the bookworms in the library became plagued, we have released related tasks. At the beginning, no one took this task. We had no choice but to set it as a time-limited task that must be completed to enter the library. , The task load has risen, but all the students doing this task are not satisfied, and some people have complained to the school, which makes us very painful."

"We don't understand. The same tasks are all tasks. Why do the students who are not satisfied with the tasks we posted have complaints? Could it be that we did something wrong?"

The book spirit 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 did make a mistake. Not only did you make a mistake, you made a big mistake!" 13
