Douluo Continent: I came from Demon Slayer!

From the day Catherine officially became an apprentice, patients noticed a new plaque with the words "Butterfly House" engraved on it at the entrance of the small courtyard, and a little girl was also with Dr. Lin.

When asked, Lin Yang would always say casually, "She is my newly accepted apprentice, Catherine."

When someone asked if he still wanted apprentices, Lin Yang replied,

"That's enough for now."

This made Catherine secretly relieved, while some people beat their chests and stamped their feet, looking heartbroken.

After that, Lin Yang had a little tail following him around.

Lin Yang never talked about grand principles when teaching; he simply had Catherine follow him around and learn from her.

How to clean external wounds, how to treat insect bites, how to fix fractures, and how to diagnose internal injuries.

Once things have progressed to a certain point, Lin Yang will let Catherine do it herself.

The first time she stitched up a wound, Catherine's hands trembled so badly that she couldn't even hold the needle steady.

Lin Yang simply stood aside and watched without saying a word.

In the end, Catherine did not disappoint Lin Yang. Although her stitching was a bit rough, the fact that she dared to try was an improvement.

For a period of time afterward, Lin Yang left all the simple injuries to Catherine, giving him more time to cultivate and try to develop new medicines.

The coagulation powder and antidote he developed were very popular and well-received among mercenaries.

Although the price is a bit high, sometimes a packet of clotting powder can save a life.

In this way, Butterfly House had its own source of income, instead of relying solely on Lin Yang's financial contributions.

As the reputation of Butterfly House grew, many mercenaries and ordinary people came to Butterfly House for treatment, which naturally offended other pharmacies and clinics.

Trouble soon came knocking, and it started with two second-ring Soul Masters.

When facing a Soul Master, most ordinary people feel fear and dread.

If Lin Yang were an ordinary person, he might have accepted his fate, but unfortunately... Lin Yang is not.

Since those two Soul Masters stepped into the Butterfly House, no one has ever seen them come out again.

The only difference was that Catherine's teaching now included a cadaver and a human skeleton model.

That evening, the manager of Huichun Pharmacy, the middle-aged woman who had previously tried to recruit Lin Yang, received a "return gift".

A peeled-off face, a heart, and a gold soul coin.

When the middle-aged woman woke up and saw these terrifying things by her bedside, she immediately urinated.

Lin Yang's words of warning were: shamelessness and a lack of conscience!

The gold soul coins were Lin Yang's reminder: it's just a job, there's no need to risk your life!

This middle-aged woman was merely a manager, a pawn that had been pushed out.

Lin Yang didn't kill her because he didn't want to cause any unnecessary trouble.

In this Heavenly Dou City, strength is important, but rules are equally important.

The middle-aged woman clearly understood Lin Yang's warning; her expression changed several times before she finally sighed helplessly.

She was just an ordinary person, while the other party was clearly not a simple doctor; the two were not even on the same level.

"Forget it, they're just peasants, how much money can they make? Our main target is still the Soul Hunting Group and those Soul Masters."

"Understood."

.......

Inside the Butterfly House, Catherine was hanging out the freshly washed sheets to dry, and the air was filled with the sweet scent of soap.

Just then, a dark shadow swept over her head, growing larger and larger until it covered her entire body in the blink of an eye.

"A letter has arrived! A letter has arrived!"

A slightly sharp cry descended from the sky, and then a large bird, half a meter long, flapped its wings and landed steadily on a nearby shelf.

Its entire body was covered in smoky gray feathers, its head was tilted, and its pointed beak opened and closed, actually speaking human language, which looked quite mysterious.

This is a type of spirit beast called the Wind Falcon, which is quite common.

It doesn't have any special attack power, but it does have one thing in common: it's fast.

Tian Dou City is nearly two thousand kilometers away from Shrek Academy, which is well beyond the range of the Hidden Energy Connection.

For easier communication, Lin Yang used his blood to modify two wind falcons: one named A-Da and the other A-Er!

After obtaining the blood, these two wind falcons not only became faster and more enduring, but also gained a stealth-type blood demon technique.

He was simply the perfect messenger.

They can deliver letters from Shrek Academy to Tiandou City in just eight hours.

Among them, A-Da is responsible for contacting Lin Yang and Xiao Wu, while A-Er is responsible for communicating with Grandma Susie.

Catherine was already used to Ah Da's special circumstances and didn't even look up.

"Okay, okay, you're yelling so loudly, you're going to deafen me."

Ah Da shook its feathers in dissatisfaction.

Catherine removed the letter from its back, then took out a special piece of jerky, waved it at Ah Da, and tossed it over.

"Ah Da, catch!"

Ah Da pounced and snatched the jerky in his mouth, devouring it in just a few bites. After finishing, he even smacked his lips.

The feathers, which had been slightly droopy due to the long flight, instantly perked up.

"Catherine, delicious!"

Catherine smiled and reached out to give the bird's head a couple of hard pats before letting Ah Da leave.

She then took the letter and went into the room, knocking on the laboratory door.

"Teacher, there is a letter for you."

Soon, Lin Yang came out of the laboratory, took a thick letter, and smiled: "Go ahead and get busy."

Catherine tactfully withdrew, closing the door behind her.

Lin Yang sat down by the window, opened the envelope, and found a thick stack of neatly folded letters inside.

He opened the letter; the handwriting was crooked and messy, like a bunch of chicks crawling across it.

But this didn't stop Xiao Wu from writing down her daily events in great detail:

"I beat up Ma Hongjun again today, and Oscar was actually laughing on the side, so I beat him up too."

Lin Yang's lips twitched.

"That big bear is so mean! All I did was sneak up on him, how petty!"

"I fought two matches at the Great Soul Arena today and won both. In the second match, that Soul Master tried to ambush me, but I kicked his head off. When I came back, I found that my left leg bone was slightly fractured, but it's nothing serious, so don't worry."

Next page.

"That sleazy Oscar actually confessed to me, it's hilarious. I told him he's crazy, and he said he's lovesick. I almost threw up my dinner from last night."

Lin Yang's brow twitched slightly, and he continued reading.

"But don't worry, I beat him up on the spot and gave him black eyes. He probably won't dare to talk to me for half a month, hehe!"

"The dean thought I went too far and fined me five gold soul coins. What a greedy old fox!"

As you flip further down the page, it's mostly filled with these kinds of trivial details.

However, it was precisely these trivial details that Lin Yang paid close attention to.

After reading the letter, Lin Yang put it back, thought for a moment, and then wrote a reply.

While writing, Lin Yang suddenly had an idea.

Nottingham Academy should be on holiday these two days, so does that mean Tang Hao is about to discover that his soul bone is gone?
