Many children, many blessings: Stealing the offspring of powerful figures to cultivate immortality.

The top floor of the Pill Tower is an absolute forbidden zone for Gu Qinghan.

There are no servants or menial tasks here.

Not even a fly can get in.

The ground is paved with millennia-old snow jade bricks, so shiny they reflect light like a mirror.

The air was filled with the finest calming incense, filtered through ninety-nine arrays.

The angle at which each medicine shelf is placed, and the spacing between each jade bottle, are all incredibly precise.

This is the ultimate obsessive-compulsive disorder of a Taoist immortal physician.

But today, this restricted area has been hit by a devastating disaster.

"Click."

The crisp sound of chewing echoed in the empty laboratory.

Gu Qinghan was concentrating on refining the medicinal liquid from a ten-thousand-year-old fire lotus.

Hand trembled.

A drop of medicine veered off course and landed on the glass table with a soft "hiss".

He took a deep breath and closed his eyes.

"Snap. Snap. Ptooey."

The sound grew louder and louder, and was even accompanied by the sound of shells being spat out.

Gu Qinghan turned her head abruptly.

Jiang Yining was sprawled out on the priceless bed of ancient black ice jade without any regard for her image.

One leg was bent, and the other leg was dangling off the edge of the bed.

He was holding a handful of spiced sunflower seeds that he didn't know where he got them from.

They were really enjoying it.

The sunflower seed shells traced graceful parabolas in the air.

Then, it landed precisely on the gleaming, snow-white jade floor tiles.

Some of the pieces even flew directly to the edge of Gu Qinghan's most treasured Nine Dragons Purple Gold Cauldron.

Gu Qinghan's breathing instantly became heavy.

He stared intently at the sunflower seed shells on the ground.

Those few black shells, on the snow-white floor tiles, looked like a malignant tumor growing on his retina.

It's blinding.

Nausea.

It's incredibly frustrating.

"What are you doing?" Gu Qinghan practically spat out the words through gritted teeth.

Jiang Yining spat out the shell from her mouth.

She blinked innocently.

"Have some sunflower seeds, Tower Master? Would you like some? These are some I brought up from the lower realm, roasted with five-spice spiritual energy, they're crunchy."

She even kindly handed one over.

Gu Qinghan looked at her greasy fingers.

Then look at the chalcedony bed she had just lain on, which was originally pure white and flawless.

The surface is now covered with sunflower seed crumbs.

hum-

The string of "reason" in Gu Qinghan's mind snapped.

He strode over.

A chill emanated from his body.

Seeing his aggressive demeanor, Jiang Yining shrank back into the corner of the bed.

"What are you doing? If you don't want to eat, then don't. Don't hit me. I'm your key experimental subject; you can't afford to pay for the damage if you break me."

Gu Qinghan stood in front of the bed.

He looked down at her.

His chest heaved violently.

Just when Jiang Yining thought he was about to lose his temper and throw her out.

Gu Qinghan suddenly raised her right hand.

His slender fingers formed an extremely complex hand seal.

A pure white light shone from his fingertips.

"Dust Cleansing Technique!"

A white light swept across.

The sunflower seed crumbs on the bed disappeared instantly.

The melon seed shells on the ground vanished into nothingness.

Even the spiced melon seed scent in the air was completely purified into a cool, medicinal fragrance.

The whole world became spotless once again.

Gu Qinghan breathed a long sigh of relief.

The furrowed brows finally relaxed.

He gave Jiang Yining a cold look.

"No impurities are allowed on my top floor. If you dare to create any more garbage, I'll throw you into the alchemy furnace to be burned as firewood."

After saying that, he flicked his sleeve.

He turned and walked back to the workbench, preparing to continue refining the medicinal liquid.

Jiang Yining watched his back straighten up again.

A wicked smile curled at the corner of his mouth.

That's it?

I thought it was something really impressive.

It turns out he was a late-stage obsessive-compulsive disorder patient who could only maintain his cleanliness obsession through magic.

She reached into her sleeve pocket.

He took out an oil paper package.

Inside was a piece of dried Crimson Flame Snake meat, roasted until it was dripping with oil.

This was her stockpile of food made from the flesh of a Mahayana-stage demon beast in the lower realm.

It sizzles and releases oil, with a wonderful aroma.

Jiang Yining tore off a piece and put it in her mouth.

Gu Qinghan had just picked up the jade tweezers used for purification.

The rich aroma of roasted meat filled his nostrils.

His hand froze.

She nearly crushed the jade tweezers and turned her head away.

Jiang Yining was holding up the greasy jerky, eating it with her mouth full of oil.

A drop of golden grease slid down the corner of her mouth.

"Tick-tock".

It landed on the snow-white jade floor tiles.

Gu Qinghan's pupils suddenly contracted.

He felt as if someone had squeezed his heart hard.

"Jiang! Yi! Ning!"

Gu Qinghan roared in anger.

Jiang Yining looked at him with an innocent expression.

"Lord Tower Master, I'm hungry."

"Your 'Marrow Cleansing and Bone Scraping Soup' has completely drained my energy. If I don't replenish my energy, how can I cooperate with you in that experiment of devouring erysipelas tomorrow?"

She spoke with conviction.

"This is the flesh of a Mahayana-stage demon beast, highly nutritious. Only when I'm full can I produce higher-quality blood for your research, right?"

The logic is perfect and flawless.

Gu Qinghan was speechless.

He took a deep breath and forcefully suppressed the urge to strangle her.

He took a white jade bottle out of his storage ring and slammed it heavily on the table.

"This is a top-grade fasting pill! One pill is enough for a year! Take this!"

Jiang Yining pursed her lips.

"It has no taste. Eating that stuff is like chewing wax. It affects my mood. When I'm in a bad mood, the Divine Tree's absorption efficiency decreases. Tower Master, you wouldn't want the experimental data to be biased, would you?"

Gu Qinghan felt a tightness in his chest.

He has lived for over a thousand years.

The monks who met him either revered him like a god or feared him like a tiger.

I've never seen anyone so reckless as to dare to cross his bottom line and then use a set of twisted logic to completely shut him down.

"Tick-tock".

Another drop of oil fell to the ground.

Gu Qinghan's eyes twitched violently.

He couldn't take it any longer.

He raised his finger.

"Dust Cleansing Technique!"

The oil stains on the ground disappeared instantly.

Jiang Yining's eyes lit up as she watched his skillful movements.

"Lord Tower Master, your Cleansing Technique is truly masterful. How about this: I'll eat my food, and you can clean yours. We'll leave each other alone?"

Non-interference?

Gu Qinghan laughed in exasperation.

He was a powerful cultivator at the Dao Inquiry Realm, and the master of the Pill Tower.

Now he's reduced to a menial servant sweeping the floor behind a woman?

But he just couldn't bear to kick her out.

That was the most perfect experimental subject he had encountered in thousands of years.

"You eat it." Gu Qinghan gritted his teeth.

He gave up on refining the medicinal liquid altogether.

He moved a chair and sat three feet away from Jiang Yining.

He made a hand seal with both hands.

He stared intently at the roasted meat in Jiang Yining's hand.

Jiang Yining tore off a piece of meat, and a crumb fell out.

Gu Qinghan pointed with her finger.

A flash of white light.

The slag disappeared.

Jiang Yining took a bite of the bone and spat out a piece of bone fragment.

Gu Qinghan ordered again.

A flash of white light.

The bone fragments disappeared.

The two walked one in front of the other.

One of them was enjoying the food immensely.

One of them was gritting his teeth in frustration.

If the cultivators at the bottom of the Pill Tower looked up at this moment...

You will then find that high-frequency white light is constantly flashing in the windows of the top-floor laboratory.

"The Tower Master is practicing so diligently today," a passing disciple remarked.

"Yes, the frequency of those flashes of light... they must be trying to comprehend some kind of peerless killing formation." Another disciple said with admiration.

Top floor.

Jiang Yining ate and drank her fill.

He clapped his hands.

Gu Qinghan immediately cast the last Cleansing spell, cleaning the oil stains off her hands completely.

"Finished eating?" Gu Qinghan's voice was hoarse.

This half-hour of high-frequency spellcasting was more tiring than fighting a cultivator of the same level.

Tired.

Jiang Yining stretched.

"I'm full. By the way, Tower Master."

She suddenly leaned closer.

Gu Qinghan subconsciously leaned back.

"You said before that you wanted to study how I ingest elixirs?" Jiang Yining blinked. "I have an idea."

"Since elixir poisoning is a waste product generated during the alchemy process, why not break down the alchemy process itself?"

Jiang Yining began to spout the fallacies she had developed while refining pills in a pressure cooker in the lower realm.

"For example, you control the heat, and I'm responsible for using the divine wood to absorb all the impurities inside the pill the moment it's formed."

"Wouldn't those produced in this way be 100% pure, flawless divine pills?"

Gu Qinghan was stunned.

His mind was originally preoccupied with how to clean this woman up.

But upon hearing this...

Remove impurities?

Does energy exchange occur at the instant the elixir is formed?

This unconventional method of alchemy is theoretically... feasible!

The way he looked at Jiang Yining changed.

No longer watching a troublesome person who creates garbage.

Instead, they were looking at a priceless treasure that could break through the tens of thousands of years-old barrier to alchemy in the cultivation world.

"You..." Gu Qinghan suddenly stood up.

He grabbed Jiang Yining's wrist.

"Let's go! To the alchemy room! We'll try it now!"

Jiang Yining stumbled slightly as he pulled her.

"Hey, hey, hey! I haven't even digested my food yet! Why do you always jump to conclusions?"
