Douluo Continent: I came from Demon Slayer!

The Kingdom of Barak, where Shrek Academy is located, is extremely far from Heaven Dou City.

Not only is the Kingdom of Silves in between, but they also have to pass through an important pass—Jialing Pass!

Jialing Pass is the last barrier of the Heavenly Battle, and also the main battlefield where the war between the two gods broke out in the original world.

And now, it's just an ordinary checkpoint.

The journey of nearly a month was very long, especially traveling alone through mountains and rivers.

Lin Yang passed through the Kingdom of Silves, crossed the Jialing Pass, and finally arrived at Tiandou City without any major incidents.

From a distance, Tiandou City looks like a ferocious beast crouching on the ground, exuding a sense of historical weight.

Neither Nottingham nor Soto could compare to this magnificent city.

Even before entering Tiandou City, the wide official road was already bustling with activity, and various caravans could be seen everywhere in an endless stream.

Lin Yang followed the flow of traffic, driving his carriage slowly closer to Tiandou City.

After a routine check at the city gate, Lin Yang was told that the carriage was not allowed to enter the city.

To be precise, carriages belonging to non-nobles were not allowed to enter the city.

Lin Yang shrugged, not surprised at all. In the city of Tiandou, class distinctions would only be more pronounced.

After leaving his carriage at the carriage shop, Lin Yang walked into Tiandou City.

The Heaven Dou Royal Academy was located outside Heaven Dou City, but Lin Yang did not choose to go directly to the Heaven Dou Royal Academy. Instead, he wandered around the city alone.

It's not registration time yet; showing up unannounced will only make you look foolish.

It would be better to use this time to learn more about Tiandou City and prepare for future plans.

Lin Yang spent a few days briefly visiting several landmark locations in Tiandou City, memorizing the locations of several clinics and pharmacies.

The acquisition of whale glue and herbs cannot be stopped.

He used different identities to privately acquire whale glue, trying to avoid unnecessary trouble.

He also rented a small courtyard in a secluded alley as a temporary place to stay.

He planned to stay here until he officially enrolled at the Heaven Dou Royal Academy.

The secluded location also means less disturbance.

Ten days later, at the entrance of Lin Yang's courtyard, a middle-aged man happily accepted the money bag.

He simply weighed it in his hand and already knew its significance, then said with a flattering expression,

"If you need any more medicinal herbs next time, please just send someone to inform my herbal medicine shop."

Lin Yang nodded and gave a simple reply.

After the middle-aged man left, Lin Yang casually carried the bags of medicinal herbs in front of him into the courtyard.

First, perform some simple processing on these herbs, then sort and store them properly.

Afterwards, Lin Yang took some herbs to a room.

The room was spacious, with a large rectangular table in the middle filled with various instruments: test tubes, beakers, distillation flasks, and so on.

These instruments, so out of place in the Douluo world, were all specially made by him.

Sitting at the experimental table, Lin Yang's hands moved swiftly, peeling, crushing, extracting, purifying, and blending.

Judging from his practiced movements, this was clearly not the first time he had handled herbs.

Soon, seven or eight test tubes were placed in front of Lin Yang.

Each test tube contained a small amount of liquid, some yellow, some pale green, and some agate-like blood red.

Lin Yang placed the extracted herbal essences into a large test tube in a certain order or dosage.

Then, his pupils contracted to the size of pinpoints, and he simultaneously diverted a wisp of his mental energy to carefully sense the reaction of the solution in the test tube.

These mixed medicines seem to have undergone some kind of strange change.

It first changed from light red to light yellow, and finally turned into a completely blue-green solution.

Lin Yang frowned, tilted his head back and drank most of the solution in the test tube in one gulp. The remaining small amount of solution was a diluent he had added to his own blood.

The moment the diluent was added, the bluish-green solution seemed to be rapidly stained by something, eventually turning into a pale red liquid.

Failed!

Lin Yang ignored the changes in the test tube and simply wrote down in the notebook beside him:

The No. 18 potion, long-term use can slightly improve physical condition, but there is a very high probability of losing one's sanity after taking it. It has no resistance to ghost blood and is not worth researching at present!

There are many similar records.

He had accumulated knowledge of the medicinal properties and effects of herbs, the efficacy of medicines, and the various symptoms of failed products.

These herbs and medicines were all personally verified by Lin Yang, even the poisons were no exception.

That means Lin Yang, thanks to his ghostly body, the effects of poisons on him were minimized.

Is this considered a Douluo Continent version of Shennong tasting hundreds of herbs?

Just as Lin Yang was preparing to try other reagents, there was a rapid knocking at the door outside the courtyard.

"Dr. Lin, open the door! Help!"

Hearing the urgent cries for help, Lin Yang sighed involuntarily and muttered, "I already told you I'm not a doctor!"

Even so, Lin Yang quickly got up, left the laboratory, and opened the courtyard gate.

Standing outside the door were three or four burly men, each one big and rough. Judging from their weathered appearance, they were clearly a group of mercenaries.

Mercenaries are not part of the Soul Hunter Group; they are basically ordinary people without soul power.

They were mostly assigned thankless tasks such as guarding caravans, escorting goods, gathering herbs in the wild, or treasure hunting.

If the money is high enough, people will go even to hunt soul beasts, even if it's just to be cannon fodder to attract them.

Upon seeing Lin Yang emerge, a young, burly man who appeared to be the leader, looking to be only in his twenties, stood there with a pleading expression on his face, his posture practically humbled.

"Dr. Lin, please save my brother..."

Lin Yang followed his gaze and looked back. Behind these burly men was a simple stretcher.

On the stretcher lay a relatively young boy, his face pale and contorted in pain. He coughed up blood from the corner of his mouth from time to time, clearly barely breathing and nearing the end of his life.

Lin Yang glanced at it briefly, then said, "Bring him in!"

A smile appeared on the young, burly man's face, and he quickly called to the others, "Quick, carry Xiao Hai inside."

The group hurriedly carried the boy to an empty room.

Lin Yang asked, "What happened?"

A bitter look appeared on the young, muscular man's face.

"Actually, we don't know much either. We were camping in the wild last night as usual when Xiao Hai suddenly started acting like this. We gave him antidote powder, but it didn't work at all."

"I had no other choice but to send it to you."

Lin Yang nodded, without asking why they didn't go to find a healing soul master.

In fact, healing-type Soul Masters are highly sought-after among the upper echelons of society.

Even for just one ring, a large number of nobles were vying to take them.

As ordinary citizens, where can we find ways to contact healing-type Soul Masters?

Even if they had connections, they probably couldn't afford the expensive treatment.

Similarly, due to the existence of Soul Masters, the medical system in this world is polarized.

Powerful healing-type Soul Masters can instantly heal fatal wounds; the most famous examples are naturally the "Nine-Heart Begonia" or the "Seven Treasure Glazed Tile Pagoda".

However, the medical care for ordinary people at the bottom of society remains at an extremely backward level, and there is not even a sound medical system.

Even ordinary doctors rely mainly on experience and a superficial understanding of herbal medicine when treating patients.

Ironically, Lin Yang's current identity as a "doctor" was purely accidental.

It originated from a single Heimlich maneuver.

From then on, the neighbors recognized him as a young doctor, and people kept coming to his house for treatment.

Despite Lin Yang's repeated insistence that he was not a doctor and that they should go to a qualified doctor, it seemed to have little effect.

People still come to our door on their own initiative.

Having no other choice, and unable to simply watch the patient die in front of him, Lin Yang gritted his teeth and proceeded.

As the husband of the Butterfly Sisters, Lin Yang has some basic medical knowledge due to his upbringing and the experience he has accumulated through his "Shennong tasting hundreds of herbs" (a legendary Chinese herbal medicine practice).

After a while, he actually managed to establish himself as a "doctor".

It can only be said that this was a completely unintentional success.
