At present, the area where Lin Fei lives is located on the edge of Canghai City, which is very close to the underground black market, although the security is not good, but it is convenient for Lin Fei to act, so he has been living here before he was admitted to Xiuzhen Academy.

The reason why Canghai City can be ranked among the five major city-states in the Kunlun Realm is that Canghai Academy, which is known as one of the five major cultivation colleges in the Kunlun Realm, was built here, which made the city prosper rapidly.

In fact, the five major city-states in the Kunlun realm are closely related to the five major Xiuzhen colleges, and they are definitely the most important talent training bases in the Kunlun realm.

In this era of national cultivation, the compulsory education of laying the foundation has penetrated into every corner of the entire human society, and the basic exercises are completely free of charge to the public, and all kinds of cultivation materials for laying the foundation are also clearly marked on the market, and the supply is sufficient. Otherwise, this era would not be the best of times.

Since the invention of the "Spirit Root Gene Liquid" by the Master of Heaven more than 3,600 years ago, the human race has evolved from generation to generation, and the spiritual root has become more and more perfect, which is the foundation for the cultivation of the whole people, ensuring that everyone can become a Qi Refiner.

To use a figurative analogy, that is, the first to twelfth layers of the Qi refining period, which is equivalent to the first grade of primary school to the third year of high school, and if you want to break through to the foundation building period, you must enter the Xiuzhen Academy for further study.

According to the official regulations of the Kunlun realm, any Qi refiner who has broken through to the twelfth layer of the Qi Refining Period can participate in the unified examination of the Xiuzhen Academy, and after reaching the standard, he will join the Xiuzhen Academy of the corresponding level, so that he will have the opportunity to come into contact with the higher-level Xiuzhen Exercises.

Of course, after entering Xiuzhen Academy, it will not be free, and you need to pay high tuition, or spend a lot of time to offset the tuition fee in the form of work-study.

As for the folk, there are also so-called loose cultivators, with their own unique way of inheritance, but most of them are not officially recognized, and can only be mixed in the underground world, which can be regarded as wandering in the marginal area. Therefore, the real road to prosperity is to enter the Xiuzhen Academy for further study.

The underground world of Canghai City, located in a place called "Fallen Street", was a fishing market by the sea many years ago, and gradually fell into disuse, as the characters of the three religions and nine streams gathered here, and finally became a gray area recognized by everyone.

Don't look at this underground world in the name of "Fallen Street", but it is actually a large community, but the lack of planning makes the streets and alleys crisscrossed, the terrain is very complex, and it has become the favorite gathering place of the city fox community rats, and finally the population in this area is nearly one million.

It's just that for Canghai City, which has a population of more than 100 million, such a place is still an inconspicuous remote corner, and no one has cleaned it up.

Lin Fei has lived here since he was a child, and he is very familiar with everything in Fallen Street, and I saw him walk through a few alleys and come to the door of a small medical hall with a sign that reads "Specializing in the Treatment of Bruises".

In this era, since all people can cultivate the truth, if there is no classified management, the whole society is easy to get confused, so the cultivators are also divided into many types.

The rarest and most rare person who can be called the pride of the sky is naturally a compound cultivator like Lin Fei, but when it comes to the largest number, it is a combat-type cultivator. In addition, there are medical cultivators, artistic cultivators, scientific research cultivators, management cultivators, etc., all of which are divided according to the field in which each cultivator is best at.

The cultivators who can open a medical clinic are naturally medical-type, but in a place like "Fallen Street", most of them are black doctors who have not obtained formal practice qualifications, or some unlucky people who have had their medical licenses revoked because they have committed major medical accidents.

Lin Fei was obviously a regular customer of this small medical hall, he didn't knock on the door, but shouted directly outside the door: "Old drunkard, business has come to the door! Have you not woken up yet? Why is it at this point in time, and you still haven't opened the door?"

A few minutes later, the door of the medical hall opened, and the first thing that came out was a red rosacea, and then a very hoarse-sounding voice sounded: "It turns out that you are a little ghost, with a few children in your pocket, what kind of business can you take care of the old man? By the way, your kid just rushed to the twelfth layer of the Qi Refining Period not long ago, and now you want to prepare for the unified exam of the Xiuzhen Academy?"

Judging from the words of this old drunkard, he and Lin Fei are indeed very familiar, and even care about Lin Fei very much, otherwise he would not know so much about Lin Fei's affairs.

And as the door of the medical hall was completely opened, the full picture of the old drunkard finally appeared in front of Lin Fei.

It was a small, thin, old man, with silver hair in a mess like a chicken coop, and the only thing that stood out was his rosacea.

However, it was such a raunchy bad old man, Lin Fei couldn't help but have a sour nose after seeing him.

Although Lin Fei was born as an orphan, he still has a lot of people close to him on his growth path, such as the old drunkard in front of him who only knows his name as Lao Guo, but doesn't know his real name, is an important person who has influenced Lin Fei's life!

Lin Fei's early childhood, it is naturally impossible to be as famous as he is now in the "Fallen Street", and the reason why he did not starve to death is all because of Lao Guo's help, which is equivalent to Lao Guo pulling him up until he has the ability to live independently.

Even now, most of the prohibited items that Lin Fei has refined have to be sold by Lao Guo to help him find channels to sell the stolen goods, don't look at the conversation between them, but in fact, it is an intimate relationship like a father and a son, and a master and an apprentice.

Lin Fei has never known what Lao Guo's origin is, but one thing can be determined, that is, Lao Guo's medical skills are enough to rank among the top three in the "Fallen Street", if he is not from a famous family, how can he have such a medical skill?

Lin Fei once heard Lao Guo keep muttering and shouting "Cui'er" when Lao Guo was drunk...... Cui'er ......", but when Lao Guo woke up, he flatly denied it, refused to admit that he had lost his temper so much, and never mentioned who Cui'er was.

But it's a pity that Lao Guo didn't wait for Lin Fei to become famous, and died prematurely because of the onset of old diseases. Otherwise, with Lin Fei's strength in the future, Lao Guo really wants to have something boring buried in his heart, and Lin Fei should be able to help him solve it.
