Deposed? I couldn't be happier! I wouldn't even be a dog to the crown prince.

"Anyone who dares to disturb His Highness's rest will be killed without mercy!"

Xu Xiao's hoarse voice, like the scraping of rusty blades, combined with the murderous intent shooting from his single eye, instantly terrified Li Tai and the other princes, making them cower like quails.

"Old...Old Xu, I'm leaving now, I'm leaving now."

Holding the blueprints, Li Tai, with his round body like a ball, rolled out of the warm pavilion with disproportionate agility.

The door closed again.

Li Chengqian rolled over, grabbed the down pillow next to him, covered his ears, and continued his salted fish business.

This sleep lasted for a full seven days.

During these seven days, the small court assembly was held every day in Taiji Palace, but the chair next to the dragon throne, which represented the highest power of the Tang Dynasty, remained empty.

Every day, Fang Xuanling and Changsun Wuji would habitually glance at that empty seat and then sigh silently in their hearts.

Without His Highness the Crown Prince, the court sessions felt utterly soulless. Although the national treasury was receiving daily revenue and infrastructure construction was progressing steadily, the exhilarating feeling of being overwhelmed by a superior force was nowhere to be found.

Until the afternoon of the seventh day.

In the warm room.

Li Chengqian stretched groggily, just about to ask Wu Meiniang to bring him a bowl of chilled plum juice.

Deep in his mind, the system notification sound that hadn't been heard for a long time suddenly rang out like a series of clear copper bells.

[Ding! It has been detected that the host has not participated in any national affairs for seven consecutive days.]

[Congratulations, host, on completing the hidden achievement: 'The Pinnacle of Passive Satisfaction'!]

[The overall research and development progress of the Tang Dynasty's technology tree has automatically increased by 5%!]

[Ultimate reward being distributed... Congratulations, host, you have obtained: Basic Industrial Penicillin Extraction Technology (with a complete set of sterile culture dish blueprints)!]

Li Chengqian suddenly opened his eyes and almost fell off the rocking chair.

penicillin?!

This thing is a miracle drug that can snatch humans back from the clutches of death!

In this era of cold weapons, where even a slight cold or a knife wound on the battlefield could lead to amputation or even death, the emergence of penicillin was of strategic value no less than that of 100,000 Great Snow Dragon Riders.

"Old Xu!"

Li Chengqian wasn't even wearing shoes; he was barefoot on the Persian carpet.

"Quickly! Go to the Imperial Medical Bureau and 'invite' that old sage Sun Simiao here for me!"

Half an hour later.

Sun Simiao, the most renowned physician of the Tang Dynasty, carrying his medicine chest and panting heavily, was carried into the East Palace by Xu Xiao like a chick.

"Your Highness... Your Highness, my old bones can't withstand this kind of torment."

Sun Simiao wiped the sweat from his forehead and was about to bow when Li Chengqian grabbed him.

"Old Master Sun, stop with the nonsense. I have a miraculous formula here that can revive the dead and heal the wounded. Would you like to see it?"

Li Chengqian slammed the "Guide to Penicillin Extraction and Cultivation," which he had just extracted from the system space and transcribed on Tang Dynasty Xuan paper, onto the table.

Sun Simiao picked up the blueprints with some suspicion.

After reading just a few lines, the nearly 100-year-old physician's cloudy old eyes widened instantly, and even his white beard trembled violently.

"This... using moldy green hair to treat wounds? Extracting a miraculous medicine from this green hair that can kill 'evil poison'?"

"Your Highness, the petri dishes and purification methods described here are completely new to me, yet their principles seem to subtly align with the Great Dao!"

Sun Simiao became more and more excited as he looked at the drawings, and finally knelt down on the ground, hugging the drawings to his chest as if they were a priceless treasure.

"If this medicine truly works as described, countless lives will be saved! Especially for the soldiers on the front lines, this would be a tremendous blessing!"

Li Chengqian nodded in satisfaction.

"I've given you the blueprints. If you need any materials or craftsmen, just go to Mo Ju. I want to see this medicine in mass production as soon as possible, and distribute it to the ocean-going fleet and the soldiers stationed in Liaodong."

They sent Sun Simiao, who had fallen into a state of madness, away.

Li Chengqian lay back down in the rocking chair and leisurely crossed his legs.

A few days later, the first batch of penicillin was produced in the secret workshop of the Imperial Medical Bureau.

After clinical trials on several death row inmates, the remarkable anti-inflammatory effects, which were described as miraculous, completely shattered the worldview of all the imperial physicians in the Tang Dynasty.

The news reached the imperial court.

The entire court looked at the report on the efficacy of the medicine, which was personally drafted by Sun Simiao and whose handwriting was so messy with excitement.

The entire Taiji Hall was completely silent.

Li Shimin sat on the dragon throne, holding a report on a penicillin sample in his hand, his expression as if he had swallowed a giant ostrich egg.

"This medicine... was it something Chengqian dreamed about after sleeping for seven days straight?"

Changsun Wuji stood at the lower end, swallowed hard, his eyes filled with deep awe and an inexplicable sense of unease.

"Your Majesty, His Highness the Crown Prince hasn't even left the East Palace these past few days. He spends all his time sleeping and spacing out."

"But the Tang Dynasty's national strength not only didn't decline, but because of the appearance of this miraculous medicine, the soldiers' battlefield survival rate soared to nearly 99%!"

Fang Xuanling shook his head with a wry smile, a wry smile that showed utter resignation to something beyond reason.

"This old minister has studied the classics all his life and always believed that governing a large country is like cooking a small fish, requiring diligence day and night."

"But now it seems that our Crown Prince has truly grasped the highest level of 'governing by non-action' in Huang-Lao philosophy."

"Governing by doing nothing is nothing more than this."

Changsun Wuji sighed deeply.

"Your Highness's lack of effort is the greatest effort you can make for the Tang Dynasty."

In the days that followed, this sentence became the most popular and profound saying in the Tang Dynasty court.

At this time, Li Chengqian...

He was holding a fishing rod, sitting comfortably by the Qujiang Pool in the back garden of the East Palace.

The water shimmered, and a gentle breeze carried the fragrance of flowers.

"Wow, making salted fish is getting more and more technically demanding."

He looked at the fishing float trembling slightly on the water's surface and muttered to himself.

Even without my own efforts, the Tang Dynasty will still be number one in the world. This system truly resonates with me.

Just as he was about to lift the rod and reel in the fish.

Suddenly, a rustling sound of footsteps came from the dense bamboo forest behind us.

Li Chengqian didn't even need to turn around to know that it was definitely those idle princes and their younger brothers coming to "pay their respects" again.

"Big brother! Big brother!"

A small figure emerged from the bamboo forest.

He was a handsome young boy with delicate features, but his eyes revealed an unusual firmness and precociousness.

He was wearing a well-fitting, small-sized python robe and jogged to Li Chengqian's wheelchair.

"What's wrong, Zhinu?"

Li Chengqian turned his head and looked at Emperor Gaozong of Tang, Li Zhi, who in history should have become the third emperor of the Tang Dynasty and started the "Yonghui Era".

Li Zhi carefully straightened his clothes, and then, like a little adult, solemnly bowed deeply to Li Chengqian.

"Brother, I also want to be crowned a king."

The little boy raised his head, and in his clear eyes, a kind of ambition that refused to fall behind shone.
