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

Inside a quiet room, Yao Lao held the Purple Leaf Orchid in his left hand, his eyes slightly narrowed.

After a brief moment, he let out a slow breath. In his palm, a cold, white flame suddenly emerged.

As soon as the flame ignited, the room's temperature instantly rose.

Yao Lao remained calm as he skillfully controlled the Bone-Chilling Flame, refining the Purple Leaf Orchid until it melted into a small mass of green liquid.

He continued purifying it with his flame, extracting every impurity. Once the liquid had reached its purest form, he tossed in the Bone-Washing Flower, subjecting it to the same process.

After a series of controlled burns, the flower was completely fused into the green liquid.

With a single motion, Yao Lao carefully poured the refined liquid into a container. Now, only one step remained.

The final refinement of the demon core.

The entire alchemy process lasted for over half an hour.

Lin Yan had been watching intently the entire time, his mind completely absorbed in the process.

For the first time, he truly witnessed the art of refining medicine.

Once Yao Lao completed all the necessary steps, only a few drops of green liquid remained, still enveloped in a cold white flame.

He carefully stored them in a jade bottle before turning to Lin Yan with a faint smile.

"This is done."

"Little friend, you can now use it for training."

"One drop per session. Fill a basin with water and add the medicine. Let it soak into your body as you train."

"If you follow this method, breaking through the Tempered Body stage shouldn't be difficult."

Lin Yan's face lit up with joy.

He cupped his fists respectfully toward Yao Lao.

"Thank you, Senior Yao!"

Without wasting time, Lin Yan carefully stored away the extra bottles, leaving one in his hand.

Following Yao Lao's instructions, he filled a large wooden basin with water before dripping in a single drop of the medicinal liquid.

The moment the liquid touched the water, a rich medicinal fragrance filled the room, and the water turned a deep green.

Lin Yan removed his clothes and jumped into the basin, immersing his entire body.

The moment his skin made contact with the liquid, a powerful sensation surged through him.

As time passed, the green hue of the water began to fade.

Several hours later, the liquid had become completely transparent, meaning that every trace of medicinal power had been absorbed.

Lin Yan climbed out of the basin, dried himself, and immediately tested his strength.

He clenched his fist and felt an unprecedented power coursing through his body.

His flesh and bones felt as tough as wood and stone.

A look of astonishment appeared on his face.

"This is… the fourth layer of the Tempered Body stage!"

Originally, Lin Yan had expected to only reach the third layer with this training session.

He had not anticipated that he would jump two entire levels, directly reaching the fourth layer.

"Could it be that the medicinal herbs in this world are stronger than the ones back in Dou Qi Continent?"

Yao Lao stroked his beard thoughtfully.

However, the two of them did not dwell on the matter for too long.

After all, gaining more power than expected was a good thing.

There were still more pressing matters at hand.

"Now that your body has absorbed the medicine, it's time to train your martial arts."

"Your body needs time to fully integrate the medicinal energy. The best way to do that is through intense physical training."

"If you can push your body to its limits, you'll be able to extract every last bit of residual medicinal power before your next session."

Lin Yan nodded in agreement.

"That makes sense."

Yao Lao smiled approvingly.

Many people, when experiencing the effects of medicinal training, would become impatient and rush to absorb more.

However, Lin Yan remained calm and logical, proving that he had a strong temperament.

"Then let's start practicing martial arts."

Lin Yan got into position and immediately began training in the Lin family's Penetrating Fist.

Pa! Pa! Pa!

With each punch, a crisp sound rang out.

This was the Lin Clan's Level 1 Martial Art, Penetrating Fist.

Though it was considered a low-rank technique, it had a unique feature—if practiced to the highest level, it could unleash a series of ten consecutive explosive strikes.

At that stage, it could even rival Level 2 Martial Arts.

That was why Lin Yan had chosen this technique—its potential for growth was far greater than other Level 1 skills.

"Hmm…"

"This martial art is quite similar to the Huang-rank Dou Techniques from my homeland."

"The difference is that Dou Techniques focus on utilizing Dou Qi, while these martial arts emphasize physical strength."

Yao Lao observed Lin Yan's movements carefully.

However, to a Dou Zun-level expert, this kind of martial art was too simplistic.

Yao Lao only needed a single glance to fully understand its structure.

Stepping forward, he turned to Lin Yan.

"Little friend, pause for a moment and watch me demonstrate."

Lin Yan immediately stopped his practice and focused on Yao Lao.

With calm movements, Yao Lao threw a single punch.

Pa! Pa! Pa! Pa! Pa! Pa! Pa! Pa! Pa! Pa!

A chain of ten explosive sounds echoed through the air.

Yao Lao had instantly mastered Penetrating Fist to perfection.

"Did you understand?" Yao Lao asked with a smile.

Lin Yan nodded firmly.

"Let me give it a try."

He adjusted his stance, recalling Yao Lao's movements, and threw a punch.

Pa! Pa! Pa! Pa! Pa! Pa!

A sixfold explosion rang out.

Though he had not reached the ultimate ten echoes, he had instantly improved from his previous attempts.

"Little friend, you truly are a martial arts genius."

"To think you improved so much just by watching once…"

"Impressive!"

Yao Lao's eyes shone with admiration.

Lin Yan, however, did not let the praise distract him.

Instead, he continued training.

For several days, he repeatedly practiced Penetrating Fist.

Finally, after countless attempts—

Pa! Pa! Pa! Pa! Pa! Pa! Pa! Pa! Pa! Pa!

A tenfold explosion rang out.

Lin Yan's eyes gleamed with excitement.

"This is it… the Ten Echoes of Penetrating Fist!"

"I've mastered it!"

Yao Lao nodded in satisfaction.

After a moment of thought, he turned to Lin Yan.

"Little friend, you have remarkable talent in martial arts."

"But with your level of skill, it would be a waste to continue practicing low-level techniques."

"I happen to have a high-grade Level 4 Martial Eight Extremes Collapse. Would you be interested in learning it?"
