Cai Lin becomes pregnant after heading to the Poison Swamp.

When Shen Wen successfully refined a fourth-grade poison pill, the 'Corpse Organ Pill'.

"This is the Corpse Organ Pill. Although its name sounds unpleasant, it is essentially a healing Medicinal Pill, especially for internal organ injuries. It can eliminate damaged internal organs and rapidly grow new ones..."

Yan Li, who had been frowning, finally couldn't help but stand up. He bowed deeply to Shen Wen, his tone urgent and sincere:

"Master Shen! Your skill is truly divine, Junior is impressed! But Junior has a matter that has troubled me for many years, leaving me utterly perplexed!"

Shen Wen looked at him and nodded slightly: "Please speak."

Yan Li, having received permission, quickened his pace: "Great Master, when refining Medicinal Pills primarily made of poison, especially high-grade poison pills, it's inevitable that toxicity will dissipate during the process.

Alchemists like us are in constant contact, and even with the utmost care, it's hard to avoid being corroded by the poison. Over time, this accumulates and causes great damage to the body.

I wonder... does Great Master have a good remedy to avoid this affliction?"

This question clearly brought out the hidden worries in everyone's hearts. Even Yun Man subconsciously sat up straight, his eyes filled with anticipation.

Shen Wen heard this, shook his head gently, and honestly said:

"On this matter, I also don't have a particularly perfect solution."

He paused, seeing the undisguised disappointment on everyone's faces, and continued to explain:

"Perhaps high-grade Alchemists can protect themselves with profound Dou Qi or isolate it with an abnormal flame, but ultimately, it's not a long-term solution.

The Dao of poison pills is essentially dancing with poison, where risk and reward coexist."

However, he changed the subject and pointed out the unique advantages of the poison pill system:

"But conversely, precisely because we can use a wide variety of poisonous substances, our flexibility in selecting medicinal ingredients far surpasses traditional Alchemy.

Many rare or even extinct medicinal ingredients might find substitutes in poisonous substances with similar properties.

This is one of the greatest advantages of the Dao of poison pills."

He scanned everyone with his gaze and concluded:

"Everything in the world has its pros and cons. No Alchemy system can be perfect.

Traditional Alchemy is safe but sometimes limited by medicinal ingredients; poison pills carry higher risks but might open new paths in desperate situations.

How to weigh the choices depends on personal preference and need."

Although Shen Wen could not provide a perfect answer to the problem of poison corrosion.

His thorough analysis and the miraculously skillful refining process itself had already made Yun Man and others feel greatly enlightened, as if a new door had opened before their eyes.

Finally.

When Shen Wen threw several sixth-grade poison-attribute demonic cores, filled with violent aura, into the Medicine Cauldron.

And with exquisite techniques, he stirred the energy of heaven and earth.

Successfully refining a sixth-grade poison pill the size of a longan, entirely dark purple, with strange pill patterns slowly flowing on its surface, the entire Alchemy room fell silent.

That Medicinal Pill quietly floated in the air, emitting a heart-palpitating energy fluctuation, yet also carrying a strange sense of Perfection.

"This is the Royal Poison Pill, with similar effects to the Huangji Pill, but the medicinal ingredients are easier to find, and the refining method is also simpler. However, when consumed, there is no pain compared to the Huangji Pill."

"This Royal Poison Pill requires enduring some pain to advance by one grade."

Yun Man took a deep breath, took the lead in standing up, and bowed deeply to Shen Wen again, his voice filled with excitement and immense respect:

"Listening to Master Shen's words and observing Great Master's Alchemy is better than us working in isolation for decades!

What Great Master has taught today has pointed an unprecedented path for our Izumo Empire Alchemist Guild!"

Shen Wen smiled calmly and waved his hand, putting the newly refined Royal Poison Pill into a jade bottle.

"This is the payment for the medicinal ingredients I took from your treasury."

..."Finally, it's done."

Cao Ying and the others were in the Alchemy room, looking at the map they had spent nearly ten days drawing, which contained the location where the Netherworld Poison Flame had previously been discovered.

"It should be somewhere within this range."

Shen Wen glanced at the map. Compared to the entire Ancient Poison Marsh.

This had at least narrowed the scope by a quarter. Although it was still very large, there was at least hope.

"Moreover, with Xian'er's Calamity Poison Body and Primordial Spirit Body, the Netherworld Poison Flame often appears in places with exceptionally strong toxicity."

"Xian'er should have some induction to this type of poison vein. We'll set a one-year limit. If there's no progress in a year, we'll make other plans. First, let's refine the poison pills."

Even Xiao Yi Xian nodded at Shen Wen's words. After all, if there was no trace at all for a year.

It would be better to deal with other matters first... The flying boat slowly ascended, leaving the outline of the Izumo Empire's imperial capital far behind.

At night, Shen Wen often discussed Cultivation with Cao Ying and Cai Lin, or guided Dan Chen and Xiao Yi Xian in Alchemy and controlling their poison power.

Or he would check on Qing Lin's Cultivation progress.

Occasionally, he would also enter the quiet room alone to refine Medicinal Pills.

One day.

Shen Wen walked out of the quiet room holding a jade bottle, a hint of helplessness and amusement on his face.

Cao Ying curiously leaned over: "Husband, what good thing have you refined again?"

Shen Wen shook the jade bottle: "The old man urged me so much, I refined that 'Pregnancy Spirit Pill'."

Cao Ying was startled at first, then realized, her cheeks instantly flushing red as she playfully punched him: "Revered Master, he really is... so impatient..."

Shen Wen laughed and hugged her: "It's understandable for an old man to want to hold his grand-disciple, isn't it?"

He looked at Cai Lin, who was walking over, "Cai Lin, this Medicinal Pill can increase the chance of conception, which is especially rare for people of our Cultivation level. You and Ying'er should take it first."

Cai Lin took the Medicinal Pill, her cold and beautiful face showing no particular expression, only her earlobes slightly reddening. She nodded: "Okay."

Although Cao Ying was shy, she also knew that the higher one's Cultivation, the harder it was to conceive children, and this Medicinal Pill was indeed precious.

She took her share and mumbled softly: "Got it."

Shen Wen then looked at Xiao Yi Xian beside him, his tone gentle: "Xian'er, your Physique is special, it's not suitable for you to take it at the moment, wait until..."

Xiao Yi Xian quickly interrupted him, considerately saying: "I understand, Husband. Dealing with the Calamity Poison Body is more important right now."

She looked at Cao Ying and Cai Lin, sincerely saying, "I hope both elder sisters will bear children for Husband soon."

The matter was thus settled.

After Cao Ying and Cai Lin took the Pregnancy Spirit Pill, they didn't feel anything special. Life continued peacefully, and the flying boat kept advancing towards the Ancient Poison Marsh.

On this day, the flying boat finally arrived at the edge of the Ancient Poison Marsh.

Looking down from above, there was an endless expanse of dark green marshland below, with faint colorful mist lingering in the air.

Even through the flying boat's protective shield, one could seemingly smell the strange scent of sweet fishiness mixed with decay.

"We've arrived." Shen Wen stood by the porthole, his gaze sweeping over the area below.

Just then, Cai Lin, with somewhat hurried steps, found Shen Wen who was in the control room studying the map.

"Husband."

Her voice was still cool, but listening closely, one could detect an unusual fluctuation.

Shen Wen looked up, seeing her slightly solemn expression, his heart skipped a beat. He put down the map and walked over: "What's wrong? Why so serious? Have you sensed something?"

Cai Lin shook her head, her purple eyes looking deeply at him, her hand unconsciously resting gently on her lower abdomen.

She took a deep breath before slowly speaking in a tone that carried a hint of disbelief mixed with strange tenderness:

"My... my aura has been a bit abnormal recently, and my Bloodline also has a sensation."

She paused, seemingly confirming something, then clearly stated:

"I seem to be... pregnant."
