My hotel is full of emperors throughout history.

Suddenly, a series of extremely rapid hoofbeats were heard outside the gate.

Immediately afterwards, a shout from the guards at the gate suddenly rose in volume, a mixture of surprise and vigilance.

"Halt! Who goes there?! Ah—it's... the Golden Dragon Flag?!"

The generals in the tent tensed up.

Golden Dragon Flag?

That was a ceremonial regalia that could only be used by the emperor's personal guards or envoys carrying special edicts!

This hour is so rushed...

Li Jing's eyes flashed with a sharp light. He suddenly stood up, not even bothering to straighten his sleeves, and said in a deep voice.

"Follow me to greet them!"

Before he finished speaking, he strode out of the tent.

Hou Junji, Xue Wanche, and the others dared not delay and quickly followed, their hearts filled with doubt and uncertainty.

Could something have happened in Chang'an? Or has His Majesty issued another urgent edict?

As soon as the group stepped out of the tent, they saw torches blazing at the gate, and several riders swept in like a whirlwind. The leader held aloft a small golden dragon flag that gleamed in the firelight.

Both the knight and his warhorse were drenched in sweat, with steam rising from them, clearly indicating that they had endured an extremely arduous long-distance raid.

The knight at the head of the group, covered in dust but with eyes as sharp as an eagle, was none other than Zhang Yan, the deputy commander of the Hundred Cavalry Division, whom Li Jing had met in front of the Taiji Hall!

The riders behind him were also elites selected from among the hundred cavalry, each with an extremely tired expression, yet they still forced themselves to sit upright, their eyes scanning their surroundings warily.

What's even more striking is that each of these riders had several neatly shaped boxes tightly bound to their saddles, wrapped in thick oilcloth and leather.

The box wasn't large, but it seemed to have been carefully protected to the extreme, and even after such a frantic run, it didn't budge in the slightest.

Upon seeing Li Jing coming out to greet him, Zhang Yan almost dismounted, but because his legs were stiff, he stumbled and was helped up by his personal guards.

He didn't even bother to catch his breath, he knelt on one knee, held the Golden Dragon Flag high with both hands, his voice hoarse and strained from thirst and excitement.

"This humble general, Zhang Yan, has been dispatched by His Majesty with an urgent secret decree, traveling day and night to escort the 'Immortal Realm Secret Medicine' here! His Majesty's oral instruction: 'This item is crucial to the success or failure of the Western Expedition, and the survival of our soldiers. It is of utmost urgency. It must be delivered to the Duke of Wei personally, and there must be no mistakes!'"

The words "celestial medicine" resounded like thunder in the ears of Li Jing and the generals behind him!

Li Jing stepped forward and personally helped Zhang Yan up. Touching him, he could feel that the muscles in Zhang Yan's arms were still trembling slightly uncontrollably, which showed how desperately he had fought along the way.

He steadied himself and said in a deep voice.

"General Zhang, you've worked hard! His Majesty's kindness is boundless! Where is the medicine?"

Zhang Yan pointed to the boxes next to the saddles of the knights behind him.

"They are all here! His Majesty has strictly ordered that they be kept away from light and moisture, and handled with care. Detailed instructions on their use are also contained in this sealed box."

As he spoke, he took out a flat, small metal box sealed with sealing wax from his person and respectfully handed it to Li Jing.

"Quickly! Unload the boxes and carry them into the central command tent! Be careful! Do not bump or knock them!"

Li Jing immediately gave the order, his voice carrying a rare hint of urgency.

He himself, holding the secret box, turned around and went back to his tent first.

The generals suddenly realized what was happening and immediately began to help.

The cavalrymen of the Hundred Cavalry Division, together with Li Jing's personal guards, carefully unloaded the boxes from the horses and carried them steadily into the central military tent in pairs.

The box fell to the ground with a dull, solid thud.

Inside the tent, torches blazed brightly.

All eyes were focused on the boxes and the secret box in Li Jing's hand.

The somber and murderous atmosphere from the earlier discussion of military strategy had not yet completely dissipated, but now they were enveloped by an excitement mixed with immense hope, intense curiosity, and disbelief.

Li Jing took a deep breath, carefully used a knife to cut open the sealing wax on the sealed box, and opened it.

Inside was not an imperial edict, but a roll of "celestial silk" (waterproof oilcloth) with a unique, smooth, and tough texture. It was covered with dense writing in Li Shimin's own handwriting, and also had detailed illustrations.

Li Jing read it intently, his expression shifting from initial solemnity to extreme shock, his fingers gripping the "Immortal Silk" tightening almost imperceptibly.

He quickly scanned the detailed descriptions of antibiotics—types (penicillin, sulfonamides, etc.), symptoms they target, dosage and administration, allergy testing, syringe usage, and preparation with disinfectant alcohol—far exceeding anything imaginable for this era. He also skimmed the information on related supplies such as tetanus antitoxin, painkillers, hemostatic powder, and sterile gauze…

Even with his composure to remain calm in the face of a collapsing mountain, a monstrous wave of emotion surged within him at this moment!

This is not just medicine; it is a complete, precise, and revolutionary combat wound care system.

If the effects described can be achieved, their impact on the preservation of the army's combat effectiveness and morale will be revolutionary!

Li Jing suddenly raised his head and looked at Zhang Yan, his voice slightly low with excitement.

"Your Majesty...is Your Majesty well? Has the procurement of this item been completed...?"

Zhang Yan bowed immediately.

"Your Majesty is well! To procure this batch of 'secret medicine,' Your Majesty has spared no effort and even used... special channels. Your Majesty said: 'Soldiers shed blood for the country, and I will not allow them to die from their injuries. This medicine, though precious, is not even worth a fraction of what my soldiers possess. Inform the pharmacists to proceed with the treatment; saving lives is the priority!'"

"His Majesty……"

Li Jing remained silent for a moment, then bowed solemnly towards Chang'an.

The generals were also deeply moved and followed suit in saluting.

After the ceremony, Li Jing's eyes regained their clarity and sharpness, and he turned to the boxes and chests.

"Open the box! Order the head of the Imperial Medical Bureau and all senior physicians to come to the central command tent immediately! Hurry!"

The box was carefully opened.

Inside, neatly arranged, secured with soft padding, were rows of small, transparent glass bottles, flat aluminum foil sheets, tiny metal syringes, delicate scissors and tweezers, brown glass bottles, and snow-white bandages and gauze packs…

Hou Junji picked up a syringe, looked at the gleaming needle in the firelight, and gasped.

"This...this is the 'immortal needle' to be injected into the body? Is it really going to pierce into the flesh?"

Although he was brave and fierce, the thought of the fine needle piercing his flesh made his scalp tingle.

Xue Wanche picked up a pill wrapped in aluminum foil and muttered to himself.

"Such a small piece can reduce fever and kill bacteria? Such divine arts are truly unbelievable..."

Soon, several of the army's most experienced and gray-haired senior medical officers arrived, panting heavily.

When they saw the scene inside the tent and heard Li Jing briefly recount the contents of the "Immortal Silk," they were all struck dumb, as if by lightning.

He then rushed to the medicines and equipment, examining them meticulously as if on a pilgrimage, his hands trembling and tears streaming down his face.

"Heaven has eyes! Heaven has eyes!"

One of the elderly doctors held a small bottle of penicillin powder, his voice choked with emotion.

"If this substance is truly as Your Majesty claims, capable of suppressing erysipelas, intestinal abscesses, and various other wound toxins... this is simply a miracle of nature! It could save countless lives of fine young men!"

Li Jing didn't delay any longer and gave the order in a deep voice.

"General Zhang and the brothers of the Hundred Cavalry, you have had a long journey. Please prepare hot water and food for them to rest well."

He looked at the group of doctors.

"Gentlemen, tonight you will all stay in the specially set up tents next to the central command tent. Immediately study the 'Immortal Silk' bestowed by His Majesty, and be sure to master its basic usage before dawn tomorrow! In particular, the methods of 'allergy testing' and 'injection' must be studied repeatedly, and you must not make any mistakes!"

"yes!"
