To Lecturer Craft:

Please forgive me for not saying goodbye. By the time you read this letter, I must have been on the clipper on the way to Dunling.

It wasn't because I had any expectations of a dead place ruled by authority and the church, but that my mentor, whom I hadn't been in touch with for a long time, sent me the latest research from him, invited me to Tun Ling to give some help within my ability, and specifically mentioned people around me who were not trustworthy enough.

Frankly, I wanted to turn down the offer because I was not the kind of person who did it for personal reasons, and there were so many things I had to deal with at the Wentengang Medical College. Only this time it's different, it's for a bigger future.

Although I can fully trust his academic integrity, the progress made in this research still made me feel like I was in a dream the moment I read it, and I couldn't believe that I could personally witness such a great moment in my lifetime.

You must remember that in "The Structure of the Human Body", Edward, who likes to sign in the cervical vertebrae, has confirmed three of the traditional four-fluid theory, and the "Body Fluids", which has lasted for hundreds of years, has been reborn in the bold verification of today's people.

In this epoch-making book, the author did not finish the whole work, leaving behind a regret that has not been completed for decades - black liquor. This mysterious liquid, which symbolizes stillness and end, has never been truly found, and is even considered to be a kind of imaginary finger, the embodiment of the inhibition system.

As a new classic, this argument is regarded as an unbreakable truth, which has been sung like a holy text by people who lack the ability to think for decades, and is regarded as proof that today's medical thinking is superior to that of its predecessors.

What a ridiculous thing, what was born to break the tradition has become a new tradition, and the cervical vertebrae that seem to be smiling may be laughing at such stupid behavior? Turning a speculation that has not yet been confirmed by clear evidence into a statue of a god, the college is used as a church dedicated to it.

Now, in our own way, we have to show our respect for the sage – to completely subvert the fallacies of his theories. In an empirical way, of course.

Here, allow me to introduce to you in a less formal way my mentor, Professor Morrison, who is also the leader of the Faculty of Medicine at Tunling University.

Thanks to the development of glass-making technology for more than ten years, the increasingly sophisticated glass instruments have made experimental observation easier, so he accidentally discovered an incomprehensible phenomenon in his recent experiments. As a rigorous and careful person, the mentor will never miss this accidental incident on the grounds of "mistakes".

Due to space reasons, and a number of other considerations, the exact process cannot be described in the letter. In short, after a series of complex operations, a very small amount of black liquid is extracted from the human body.

In the following experiments, the liquid exhibited unusual properties that became more pronounced after further purification.

I'm guessing you've already thought about what I'm going to say by reading this, which is the inhibiting nature we've been looking for for a long time.

In every way, it exhibits an inhibiting effect that makes things that have vitality tend to come to a standstill, and it only takes a very small amount to achieve it. I've done some tests with samples sent by my teacher, and I've put together the results with the samples and handed them over to Lucius, who is my most trusted and gifted student here, and is qualified to know all about it.

If that's right, these two things and this letter will be handed over to you by Lucius, and you can communicate everything about it with him, but be sure not to give it away to anyone else. Experiments must also be conducted in secret, and Lucius will tell you where my private lab is.

Until I return, you can use my lab to do a more detailed, comprehensive test of this black liquid from your own perspective.

As a fellow scholar, you can understand the urgency of a person seeking knowledge. I couldn't bear such a great temptation.

The palatial palace of medicine is now close to being completed, and only the last corner is left for us to fill, and the perfection of the four-liquid doctrine in physical proof is just around the corner!

If the mentor is right, I should be able to help him accomplish this feat within three months, and return to Wenden Harbour with a brand new book to share with you. May we appreciate together the latest and most beautiful treasure in the treasure trove of knowledge.

In addition, I have a vacant house near the college that I can live in for a long time. The key is enclosed in an envelope, so feel free to use it if necessary.
