In Martial Universe, Signed in at the Start with Yao Lao's Ring

Before long, Lin Yan arrived at Qingyang Town's Trading Market.

Since he only needed to purchase basic medicinal ingredients, and none of them were particularly rare or expensive, he didn't need to go to an underground market or any other exclusive place.

Upon reaching the marketplace, Lin Yan headed straight to one of the larger medicine shops.

Using all the silver taels he had borrowed from Lin Xia, he converted the entire sum into medicinal ingredients before returning home.

Once back, he knocked lightly on his ring.

A moment later, Yao Lao's ethereal figure appeared, floating gracefully in midair.

Seeing the old man's composed expression, Lin Yan cupped his fists and smiled.

"Senior Yao, I'll have to trouble you again."

Yao Lao waved a hand dismissively, smiling.

"It's a small matter, little friend. No need for formalities."

Without further delay, Yao Lao began refining the ingredients.

Since he was only preparing medicinal liquid and not actually refining pills, the process was incredibly simple for him.

As always, he summoned his Bone Chilling Flame and directly threw in the medicinal ingredients, using the heavenly flame's power to refine them.

In just over an hour, the process was complete.

Lin Yan carefully bottled the finished medicinal liquid, storing it in multiple containers.

However, unlike before, he didn't hide them away carefully.

Instead, he strapped them onto his person.

Yao Lao noticed this and raised an eyebrow in curiosity.

"Little friend, what are you planning?"

Lin Yan chuckled.

"Well, money doesn't grow on trees, I borrowed silver, so I should find a way to pay it back. I plan to sell this batch of medicinal liquid, then have you refine another one. Senior Yao, you don't mind, do you?"

Lin Yan spoke earnestly.

Hearing this, Yao Lao laughed softly and shook his head.

"Of course not."

The effort required to refine this liquid was insignificant to him.

Moreover, Lin Yan's sense of responsibility impressed him.

There was an old saying: "A debt repaid makes future loans easier."

Yao Lao had always despised people who borrowed without returning. Seeing Lin Yan take the initiative to repay what he owed, Yao Lao couldn't help but feel a sense of appreciation.

"Good, then I have nothing to worry about."

Lin Yan smiled in relief, then immediately set off for the trading market once again.

This time, however, he didn't go to a regular pharmacy.

After all, normal pharmacies dealt in common medicinal herbs and only made small profits.

The medicinal liquid he was selling was a rare commodity, so selling it at a normal pharmacy wouldn't maximize its value.

Instead, Lin Yan made his way toward the underground trading market.

Of course, since this kind of place was more dangerous, he took precautions before entering.

He purchased a bamboo hat and disguised himself slightly to avoid drawing unnecessary attention.

Once he was fully prepared, he stepped into the underground trading market and made his way to a transaction window that looked similar to a modern bank counter.

"Please have a seat. If you have anything to trade, place it under the counter," an old, hoarse voice instructed.

Hearing this, Lin Yan didn't hesitate.

He placed his medicinal liquid on the counter.

"This is a liquid refined from various spirit herbs, designed to enhance the physique of Tempered Body cultivators, it also has excellent healing properties."

A withered hand reached out from behind the counter, grabbing one of the bottles.

The next moment, Lin Yan heard the sound of liquid dripping, indicating that the elder was testing the quality of the medicinal liquid.

Lin Yan patiently waited.

After a few moments, the old voice spoke again.

"This medicinal liquid has the potency of a Grade 3 Spirit Herb. Its medicinal properties are gentle, making it very suitable for Tempered Body cultivators. Tell me, what do you want in exchange?"

Lin Yan answered without hesitation.

"Silver. Six hundred taels."

He had borrowed one hundred taels from Lin Xia.

By selling this batch for six hundred taels, he could repay the debt and still have a considerable amount of money left over.

The old man behind the counter didn't even bargain.

"Deal."

A moment later, Lin Yan received six hundred taels in silver.

With money in hand, he immediately spent one hundred taels to purchase another batch of medicinal ingredients before returning home.

Once again, Yao Lao took action.

An hour later, a new batch of medicinal liquid was successfully refined.

Looking at the bottles of medicinal liquid before him, Lin Yan couldn't help but smile.

"Looks like I won't be running out of medicinal liquid anytime soon."

Right now, he had already reached the sixth layer of the Tempered Body stage.

There were still four layers left before he could break through to the Earth Yuan Realm.

If things went as expected, once he fully utilized these medicinal liquids, he would be able to advance to the Earth Yuan Realm.

With that thought, Lin Yan looked at the sky and nodded to himself.

"It's still early. Time to return the money."

"Hmm… I should also bring a small gift. After all, it's rare to find someone willing to lend money."

Without hesitation, he picked up a few bottles of medicinal liquid and headed out.

He quickly found Lin Xia, who was currently training in the clan's training grounds.

After all, the Lin Clan Competition was fast approaching, and after that, the Qingyang Town Hunting Tournament.

Everyone was focused on strengthening themselves to perform well in these upcoming events.

Lin Yan approached with a smile.

"Sister Lin Xia, training hard?"

Lin Xia turned to him and smirked.

"Of course! Not everyone is like someone I know, who just so happens to have already reached the sixth layer of the Tempered Body stage."

Lin Yan simply chuckled and didn't argue.

Instead, he handed her the silver.

"Here, this is the money I borrowed from you."

Lin Xia looked surprised.

"You borrowed money in the morning, and you're already repaying it at night?"

"Were you just messing with me?"

Lin Yan shrugged.

"What if I told you I already made several hundred taels off that loan?"

Lin Xia rolled her eyes.

"I'd sooner believe ghosts exist than believe you."

Still, she didn't refuse the money. Since Lin Yan was willing to return it, she saw no reason to decline.

As she pocketed the silver, Lin Yan suddenly pulled out a few bottles of medicinal liquid and handed them to her.

"This is the interest."

Lin Xia raised an eyebrow.

Lin Yan continued, speaking seriously.

"Use one bottle at a time. After training, fill a bath with water, then add the medicinal liquid, wait until the water turns green, then soak in it, don't use it too frequently. After one bath, train for a few days before using another. And most importantly—keep this a secret."

Lin Xia had initially thought Lin Yan was just joking.

But seeing how serious he looked, she nodded in agreement.

"Alright, alright. Got it. So secretive."

Lin Yan grinned and quickly left.

Meanwhile, Lin Xia finished her training and went home.

That night, after dinner, she was preparing for her usual bath when she suddenly remembered the medicinal liquid.

After hesitating for a moment, she muttered to herself.

"Should I try it? Lin Yan made it sound so serious. Maybe it actually works?Besides, he wouldn't harm me. No harm in giving it a shot."

With that thought, she opened a bottle and poured the liquid into her bath.
