Douluo Continent: I came from Demon Slayer!

Dugu Bo's concession eased the tense atmosphere between the two considerably.

"Enough with the nonsense," Dugu Bo snorted lightly, getting straight to the point.

"What's this potion you mentioned? What ingredients does it require? How long will it take to make?"

Lin Yang was slightly taken aback. He hadn't expected Dugu Bo to skip the first method and choose the second one instead.

However, he quickly figured out the key point.

The old poisoner wasn't comfortable with him just talking; he wanted to try it himself first.

Dugu Yan doesn't have a soul bone, but he definitely has one on him.

This can also be considered a test.

"The potion is very simple; I can make it anytime."

Lin Yang casually named several herbs.

Dugu Bo frowned, somewhat suspiciously: "These are all common herbs. You're not trying to trick me, are you?"

Lin Yang shook his head, his expression calm.

"Your Majesty, ordinary herbs, when combined properly, can also produce remarkable effects. Seeing is believing; you'll see for yourself once you try it."

Dugu Bo glanced at him and then remained silent.

Hmph, this kid is really wary!

"Then I'll go to your place. I want to see if you really can turn the rotten into the miraculous!"

Dugu Bo couldn't wait a moment longer. He grabbed Lin Yang's shoulder, took off, and sped into the city, arriving at the location of the Butterfly House.

"Is this your clinic?"

Dugu Bo looked at the unremarkable courtyard, his suspicion growing stronger.

"good."

Lin Yang pushed open the wooden door and bumped into Catherine, who was tidying up herbs in the yard.

"Teacher, you're back..."

"Hmm," Lin Yang nodded.

"After you've put the herbs away, go and rest. Don't wait for me for dinner."

"Okay, teacher!"

Catherine stole a glance at the imposing Dugu Bo and obediently responded.

As a child from a poor family, she knew best what to do and when, and she wouldn't ask questions she shouldn't.

Afterwards, Lin Yang brought Dugu Bo to his laboratory.

As soon as Dugu Bo entered the room, he was attracted by the strangely shaped utensils that filled the room.

Are all these bottles, jars, and winding glass tubes related to medicine making?

This was completely different from what he had imagined alchemy to be; no wonder the kid insisted on coming here to do it.

Lin Yang ignored his expression and casually said, "Sit wherever you like. I need some time to prepare."

"Okay, go ahead!"

Dugu Bo responded and began to tour the laboratory.

After circling around, he stopped in front of a wooden shelf filled with bottles and jars, picked up a test tube containing a pale green liquid, and shook it slightly.

"What is this?"

Lin Yang glanced at it, then lowered his head again and continued picking through the pile of medicinal herbs.

"Antidote; it can neutralize the toxins of most soul beasts."

Dugu Bo didn't say anything, put the test tube back in its place, and continued to wander around, finally stopping in front of a wall.

The walls were covered with various drawings, including diagrams of human blood vessels, bones, and meridians, as well as some that looked like cross-sectional diagrams of the internal structure of some kind of animal.

Dugu Bo stared intently at the blueprints, his expression gradually shifting from casual to serious.

This kid's research on the human body is surprisingly deep.

Even he is far inferior in this respect.

Thinking about it carefully, it's absolutely terrifying!

It was as if he had personally dissected a person layer by layer, inside and out, more than once.

Otherwise, these drawings could never have been so detailed and accurate.

The distribution of blood vessels, the texture of muscles, and even the distribution of internal organs and bones are incredibly detailed.

Dugu Bo naturally didn't see anything wrong with it; on the contrary, he gained more confidence in Lin Yang, since at least this kid really had the ability.

Then, he moved to Lin Yang's test bench.

I watched him process each herb, grinding what needed to be ground, extracting what needed to be extracted, then distilling, purifying, and shaking...

The entire process was smooth and seamless, without the slightest hesitation.

"Boy," Dugu Bo suddenly spoke.

"Who taught you all these skills?"

Lin Yang continued working with his hands, his tone calm: "Just something I figured out myself."

"Figure it out yourself?"

Dugu Bo scoffed, "Do you think I'm a three-year-old?"

"If Your Majesty doesn't believe me, there's nothing I can do."

Dugu Bo was speechless for a moment, and felt even more frustrated.

Getting the truth out of this kid is harder than climbing to heaven.

Soon, half an hour passed quietly.

Lin Yang stopped what he was doing. He now held a test tube in his hand, containing a pale yellow liquid that emitted a faint medicinal fragrance.

"It's ready!"

Dugu Bo quickly stepped forward, his eyes fixed on the potion, his throat bobbing, his voice a little dry.

"How do I use it?"

"Drink it directly."

Lin Yang handed the test tube to Dugu Bo.

"Your Majesty possesses formidable cultivation. While the potions made from these common herbs may be slightly less effective, they are sufficient to verify their usefulness."

Dugu Bo nodded slightly: "If it really works, I will definitely not go back on my promise."

After saying that, Dugu Bo took the test tube and tilted his head back to drink it down.

Then, following Lin Yang's instructions, he circulated his soul power, gradually channeling the toxins from his body into his soul bone.

A moment later, Dugu Bo opened his eyes, a flash of wild joy in them.

it works!

Although only a tiny bit was expelled, he could definitely feel that the poison that had plagued him for most of his life had been successfully introduced into his soul bone and completely suppressed.

If it were Yan Yan, only five or six treatments would be needed to completely eliminate the toxins from her body.

Yan Yan is saved!

Dugu Bo was overjoyed. The stone that had been weighing on his heart for more than ten years finally cracked open at this moment.

"How is Your Majesty feeling?"

In fact, Lin Yang didn't need to ask any more questions; he could draw the conclusion just from Dugu Bo's expression.

"Not bad," Dugu Bo nodded, his voice tinged with excitement.

"This medicine...works!"

Lin Yang nodded slightly: "If possible, Your Majesty, could you bring Senior Sister Dugu over so I can examine the situation and then determine the appropriate dosage for the medicine?"

"No," Dugu Bo resolutely rejected.

"I want Yanyan to use the first method!"

Lin Yang looked troubled: "Your Majesty, this requires rare and precious materials suitable for a martial soul, this..."

"I have!"

Dugu Bo spoke with absolute certainty, his gaze fixed intently on Lin Yang.

"However, I need you to help me identify which rare and precious herbs are suitable for Yan Yan."

Without a doubt, Lin Yang's performance had completely won over Dugu Bo, and he was finally willing to reveal his secret.

"good!"

Lin Yang nodded without hesitation.

Without a doubt, Dugu Bo was referring to the Yin-Yang Well of Ice and Fire, which is also Lin Yang's target.

Although the whole process was somewhat different from what he had expected, he finally came into contact with the Yin-Yang Eye of Ice and Fire.
