My hotel is full of emperors throughout history.

Meanwhile, in Chang'an, the capital of the Han Dynasty, at the northern gate of the Weiyang Palace, the armory and forbidden garden were located.

The vast area that was originally used to store armor and chariots was now strictly cordoned off, with three layers of Imperial Guards standing at attention with halberds, strictly prohibiting anyone from spying.

In the center of the venue, those heavy trucks stood there quietly, like steel behemoths descended from the sky, looking extremely out of place with the surrounding palaces.

Crown Prince Liu Ju stood in front of the carriage, dressed in the everyday clothes of a crown prince.

Beside him were high-ranking officials, led by Grand Minister of Agriculture Sang Hongyang, Director of the Imperial Household Department Zhao Yu, and Grand Master of Works Gongsun He, as well as dozens of top craftsmen urgently summoned from the Imperial Household Department, the Directorate of Works, and the Examination Office.

Most of these craftsmen had graying temples, rough fingers, and eyes that held a mixture of fear, awe, and an almost obsessive curiosity.

"How is this?"

Liu asked with a smile.

"Its diameter exceeds five feet (approximately 1.15 meters in the Han Dynasty)!"

The craftsmen gathered around the tire, exclaiming in disbelief.

"Neither metal nor wood, as elastic as leather, as hard as iron, cast in one piece without any mortise and tenon joints? Such a material is unheard of!"

"The difference between the center of the left front wheel hub and the center of the right front wheel hub, and between the left rear wheel hub and the right rear wheel hub... is no more than half a finger's width (approximately 1 centimeter)!"

An old craftsman's voice was filled with disbelief.

Another group of craftsmen tried to insert thin bamboo strips into the seams of the steel plates, but failed and stared at the seams in silence for a long time.

How exactly was it connected?

Why isn't there even the slightest gap?

That's unreasonable!

Some craftsmen even use a feather to gently sweep away the dust from the steering linkage joint.

When they saw the exposed, oil-slicked bearing structure, the old craftsmen almost fainted.

Based on their external shape and tiny gaps, they used their experience to deduce the internal structure on the sand, creating sketches as complex as star charts.

"There must be dozens... no, hundreds of high-quality steel balls rolling in unison here!"

A craftsman specializing in axles had a hoarse voice and unfocused eyes.

"Only in this way can the steering force be easily transmitted to such a massive ship... But how are these steel balls inserted? How are they held in place? How are they lubricated? This... this is the pinnacle of ingenuity!"

The more detailed the measurements and the more data collected, the deeper the chill in the hearts of the craftsmen.

The initial excitement and curiosity were gradually replaced by a bottomless sense of confusion and frustration.

"This thing..."

Gongshu Ming finally stopped his fingers, which were almost raw from being rubbed raw.

He looked up, his face not filled with fanaticism, but with a shock that was almost utterly devastating.

"How exactly was it made?"

"It was not forged by human hammering...nor is it any casting method we know of."

"The components seem numerous, yet they form a unified whole."

"Its size is as large as a house, yet its precision surpasses that of a clock."

"The material is neither metal nor wood, yet it combines the properties of strength, flexibility, toughness, and elasticity..."

He staggered a step and bowed to Liu Ju and the group of important officials.

"Your Highness...we...we are using mortal standards to measure the work of nature!"

Then, pointing to the heavy truck, he said with absolute certainty.

"This item is definitely not from this world!!!"

Upon hearing this, Liu Ju showed no surprise; instead, he chuckled.

"Don't rush! This thing really can't be made right now."

"As long as you can learn something from this, that's fine."

Then, Liu Ju pointed to the front of the car and laughed.

"You've only seen its bones and muscles so far, but you haven't witnessed its power yet!"

"This thing... can actually move!"

"active?"

Everyone was silent for a moment.

If it has wheels, it's normal for it to be able to move.

But Liu Ju's next words made everyone gasp in shock.

"If fuel is plentiful and the load is full, this thing can easily travel a thousand miles a day."

"Hiss~!"

Everyone looked at the heavy truck.

When fully loaded?

How can something this big, fully loaded, travel a thousand miles a day?
