"Mr. Zeng, since you are an explorer from afar, you should be no stranger to enhanced serum, right?"
As Ye Feng pondered Han Xianxing's condition, Han Qiuli spoke again, "Injecting enhanced serum can indeed grant people immense strength, but this strength comes at a price!"
"The power gained from using enhanced serum has significant side effects on the human body."
"As the number of uses increases, these side effects become more pronounced..."
Han Qiuli paused, her expression seemingly hesitant.
After a moment, Han Qiuli seemed to have made up her mind. She stepped forward, glanced around outside the door, then turned and closed it.
"Although my father is very powerful, possessing the strength of an ancient creature like the Tyrannosaurus Rex... he also suffers greatly from illness... persistent pulmonary hypertension, causing violent coughing that has worsened his health..."
"Because of this, my father hasn't used the Tyrannosaurus Rex's power much in recent years..."
"And this is also why I've been looking everywhere for Sildenafil tablets. This medication is highly effective in treating pulmonary hypertension!"
"But in this post-apocalyptic world, medicine is scarce. The pharmacies and pharmaceutical factories of the old world have likely been plundered by countless explorer factions..."
After closing the door, Han Qiuli quickly explained to Ye Feng in a low voice.
"Miss Han... we don't seem to be very familiar. You're telling me a secret of this magnitude?"
Ye Feng looked at Han Qiuli with great surprise.
"I..."
Ye Feng's question left Han Qiuli momentarily speechless.
She was silent for a while before continuing, "Mr. Zeng, do you remember the sanitary pads I bought from you before?"
This time, for some reason, Han Qiuli used a respectful title.
"Yes? What's wrong?"
"Is there something wrong with the sanitary pads?"
Hearing this, Ye Feng couldn't help but frown.
"No, no!"
Han Qiuli quickly waved her hand, "The sanitary pads are fine, and I've already given the collected sanitary pads to a Grand Runemaster in the City of Arcane Arts!"
"When that Grand Runemaster saw the sanitary pads I brought out, they showed a rare expression of surprise..."
Han Qiuli recalled the scene from just yesterday, her expression filled with surprise.
"A Grand Runemaster in the City of Arcane Arts? Surprised?"
Ye Feng scratched his head, not quite understanding why Han Qiuli was telling him all this.
"Yes!"
Han Qiuli nodded, "It's because of the brand. The Su Fei sanitary pads you sold us. This brand seems very rare. At least, I haven't seen this brand of sanitary pads before..."
"And when that Grand Runemaster learned that I bought them from you, they surprisingly told me that you might be able to help with my father's condition..."
"And you come from afar, and you possess such a rare item as sanitary pads, coupled with the recommendation from that Grand Runemaster..."
"That's why I came to find you..."
Han Qiuli's tone was very respectful, and there was even a clear plea in her eyes.
She knew the power and status of that Grand Runemaster in the City of Arcane Arts very well, and they wouldn't speak carelessly.
"This..."
After listening to Han Qiuli's words, Ye Feng's brow furrowed tightly.
He basically only sold Su Fei sanitary pads to people on the survival channel, occasionally trading a few packs with people along the way, but those people preferred food...
And among those who bought sanitary pads from him on the survival channel, the most frequent buyers were those with IDs like Yan and Ying...
Ying hadn't logged in for a long time for some unknown reason, while Yan would occasionally buy a few packs from him...
Speaking of the City of Arcane Arts, Ye Feng had given Bing Shang hundreds of sanitary pads...
"Does Bing Shang have any connection to that Grand Runemaster in the City of Arcane Arts?"
A thought involuntarily crossed Ye Feng's mind.
"Mr. Zeng?"
Seeing Ye Feng staring blankly at the wall, Han Qiuli couldn't help but speak.
"Uh... to be honest, on my way to the Tyrannosaurus Rex, I opened a Mithril Treasure Chest, and it coincidentally contained a box of Sildenafil tablets!"
"That treasure chest was ridiculous, such a large volume, and only contained a box of Sildenafil tablets!"
Ye Feng's expression was indignant and lifelike.
"However, can you tell me why your father developed pulmonary hypertension symptoms after injecting the enhanced serum?"
"If I recall correctly, this symptom is caused by injecting the Desperate Serum, right?"
Pausing, Ye Feng asked the question that was on his mind.
"This... I only know that Father once injected something called Enhanced Serum No. 1. As for the Desperate Serum, I'm not very clear, but I can go ask my father!"
Han Qiuli quickly replied to Ye Feng.
"Is that so... Could it be that to withstand the power of Enhanced Serum No. 1, the Desperate Serum is also required?"
Ye Feng frowned slightly.
He remembered encountering that person in Zhanbi City who had also injected Enhanced Serum No. 1 and transformed into a giant beast like Godzilla. However, he couldn't control that immense power and eventually broke down...
At that time, the guy had said something like, "Damn Dr. C... must have hidden some crucial information... The use of enhanced serum of this caliber absolutely has special conditions..."
"I'll give you two pills first. Have your father try taking them to see if they have any effect!"
"If there's nothing else, you can leave. I have things to do!"
As he spoke, Ye Feng reached into his pants pocket and took out two blue 'Happy Pills,' handing them to Han Qiuli.
"Oh, right, the exploration of the Red Bank Ruins is tomorrow, isn't it? Try not to let anyone disturb me. I'm very busy, and we have our own food."
Pausing, Ye Feng added.
"Ah... Ah?!"
"Mr. Zeng, you... you..."
Ye Feng's prompt and generous offer of Sildenafil tablets caught Han Qiuli by surprise. She hadn't even considered what to trade with Ye Feng...
"Don't just stand there, take them!"
"Also, stop calling me 'you' and 'sir,' you're making me sound old!"
Seeing Han Qiuli in a daze, Ye Feng extended the hand holding the small blue pills further.
"Oh, okay! Okay!"
Han Qiuli finally came to her senses, happily accepted the Sildenafil tablets, carefully wrapped them in a handkerchief, and stored them in the spatial rift fragment ring on her hand.
"Mr. Zeng, due to some unexpected changes, we need to reconfirm some details about the Red Bank Ruins."
"The original plan to go to the Red Bank Ruins tomorrow morning has to be postponed by one day. However, if you are in a hurry, you can still go tomorrow, and we can send people..."
Before Han Qiuli could finish speaking, Ye Feng waved his hand at her.
"Oh, no need. Let's just postpone it by a day."
Ye Feng was originally quite anxious. After all, with only one day, even with the Fire Seed Record, understanding the small intermediate protective mecha, and even the silver-white mecha in the Spirit Gathering Ring, would be a significant pressure.
But with two days, there would be much more time.
"Then... I'll notify you then!"
Hearing this, Han Qiuli spoke again.
"Yes, if there's nothing else, you can leave!"
Ye Feng nodded and issued the eviction order again, without any politeness.
"Alright!"
Han Qiuli was also very straightforward and turned to leave, without any hesitation.
After Ye Feng saw Han Qiuli running off through the window, he pulled the curtains shut, activated the infrared alarm system, and then began to study the Fire Seed Record...
