But when it comes to the metallurgical processes

Lu Cheng held the black card in his hand, his thoughts had already returned to a millennium ago.

What should I do What can I do

In the course of history, internal troubles have weighed far more heavily on China than external threats.

Although feudal etiquette brought relative stability and contributed to the continuation of civilization, it also greatly restricted the development of thought.

I recommend using a source switching app to read books. It's really useful! You can download it quickly and give it a try.

Lu Cheng knew that in the world before he traveled, China's situation had been extremely dangerous for a time. But fortunately, generation after generation of ancestors had worked tirelessly behind the scenes, and they had survived the most difficult years.

While Lu Cheng experienced a thousand years, the Seven Laws changed seven times.

Since the Qin Dynasty, external threats have been far more serious than internal troubles!

When the First Emperor Qin was attacked, he was surrounded on three sides by Han troops. The military might burned as far as Chang'an City, until Li Tang, the sky was dark and dim, and mountains and rivers were broken.

This made Lu Cheng understand that the extraordinary world he was in was even more dangerous. One wrong step, and he would be doomed forever.

The Hundred Schools of Thought flourished again, but this time it was forced upon them.

This enabled the four social classes—scholars, farmers, artisans, and merchants—to unite and work together to overcome the national crisis.

Stagnation and clinging to old ways will lead to falling behind. That is the greatest lesson.

It must develop, and keep developing.

There is no way out.

Lu Cheng knew that the Hundred Families, after a thousand years of effort, had turned the tide of battle. Now that the Lùkǎ is disbanded, it wasn't completely dissolved.

The time and epic of the Card Realm, like its geography, are fragmented, a series of cards that can be defined and modified by a sufficiently powerful cardmaster.

Just as *The Odyssey* was originally intended to take place after the Trojan War, and the Sanctuary cleverly wove them together.

If guided by human hands, the afterglow of the Second Hundred Schools of Thought would be like spring rain, seeping and expanding to encompass all realms.

So, let your thoughts wander.

Is there a historical record of compiling the skills of various schools into a single book

That's it.

Looking back at the history of technological development.

From the Qin and Han dynasties, from "The Nine Chapters on Mathematical Arts" to "Qi Min Yao Shu" and then to "Shui Jing Zhu".

During the Song Dynasty, Shen Kuo compiled the skills of previous generations and wrote the monumental work "Dream Creek Notes".

Until the end of the Ming Dynasty, the great scientist Song Yingxing compiled the best of what was known in the world and wrote the encyclopedia of technology, *The Exploitation of the Works of Heaven*.

The entire book compiles agricultural and artisanal techniques, including machinery, brick-making, ceramics, coal mining, and oil pressing.

But because of the God Card invasion, history rebooted in a legendary epic scale.

The Lu Kaka experienced major events such as the Millennial War, the Second Contention of a Hundred Schools, and the revival of heaven and earth's spiritual energy.

If the war were to drag on until dawn, what would Song Yingxing's *Tian Gong Kai Wu* (Second Hundred Schools of Thought Era), a book from the *Lishu*, look like

Perhaps it is a superlative skill that encompasses spiritual arts, forging, cultivation techniques, secret arts, and sorcery!

Putting this skill card as the core equipment in the workshop would be like having everything you could possibly need.

While expertise in some areas might be lacking, it's definitely comprehensive.

But unfortunately, Lu Cheng can't go to Lü Ming.

Although the Gatekeeper said after the Millennial War he could redraw the Seven Laws in the form of a secret realm, it cost money.

Lu Cheng had never been there. With Li Ming's size, Lu Cheng simply didn't have enough energy to draw it out of thin air.

However, this doesn't mean he has no way out. He still has a background to rely on. As one of the chief officers of the Daming Naval Headquarters (鎮海司), Lu Cheng can find another Ming Dynasty official who is also lost in Han Dynasty, 【Zheng He】!

To manifest this secret realm, Lü Cheng paid a great price, but it was necessary.

Above the vast sea of Law Han, the fleet of the Zhenhai Division maintained its wartime course, advancing forward.

In the instant when the Moon God fell, Rika vanished. Lu Cheng didn't even have time to visit Donghua before being kicked out. Now, back in familiar territory, Lu Cheng discovered that the recreated secret realm time was a mirror of the day of the decisive battle!

The young Lion King discovered this long-range strike fleet deployed in the East China Sea, causing the Moon Goddess to unleash a tidal wave on the area and have sea beasts surround the fleet.

The Zhenhai sailors fought with firearms, engaging sea beasts while battling the storm and tide, hoping to reach their destination as quickly as possible.

In the final battle, the Zhenhai Fleet lost two-thirds of its warships and suffered over half its sailors killed or wounded.

These brave sailors didn't even know the war was over, they were still fighting the enemy, and the fleet was still moving in the direction they were instructed.

Suddenly, in the sky, a round moon hung high like a bright mirror.

As the tide receded, tens of thousands of sea creatures fled in panic.

An old friend came by riding the wind.

We won.

When Lu Cheng brought the news to the captain's cabin, Zheng He trembled and stood up.

He lost a leg, ripped apart by a sea beast the day before. He lay unconscious for a day and as soon as he woke up, he jumped right back into command.

Leading the fleet, receiving orders to sail west and find the lost moon, searching for light in the dark ages. The fleet strayed off course to the battlefield where all warships were overheating and scrapped due to long-range support of the Youzhou battlefield. The fleet's position was exposed, putting it in extreme danger.

"Yes." Lu Cheng went up and supported him, murmuring, "You won."

"That's great," Zheng He said, his face still pale, muttering to himself.

"But the first culprit escaped, there's a bigger world out there." Lu Cheng slowly sat down opposite him, and said.

“At least two warships, the Fata, can still be repaired. We can still fight!” Zheng He listened, his brows furrowed.

At this point in the war, to win, one must achieve a complete victory.

"Lord Zheng, I have something more important to ask of you." Lu Cheng shook his head and collected himself: "I'm currently leading troops overseas to pursue the Death Raven. There's a big favor I need you to do!"

"What can I do for you" Zheng He asked.

Lu Cheng took a deep breath.

"The era Zheng DaRen lived in will produce a definitive book, the expeditionary force needs it!"

"What book How could I not know" Zheng He frowned.

"It's about what happened after Zheng Da! This book will encompass everything." Lu Cheng said seriously.

Zheng He shook his head: "I don't quite understand, Lu Si Zheng. Just tell me what I should do."

"The heavens are restoring balance, and the Zhenhai Division will soon return to the Ming Dynasty from here," Lu Cheng said slowly.

Zheng He knew Lu Cheng had something to say and listened quietly.

The lost fleet will once again pass through the spacetime tunnel without incident. From the tunnel, you will get a glimpse of seven worlds within the Law.

"Lu Si Zheng, are you planning to lead the Zhenhai Si to take advantage of this situation and attack Qili" Zheng He's gaze was solemn.

Lü Cheng stood up, bowing respectfully. He was just about to speak.

Boom!

Ten thousand bolts of lightning flash!

Lü Cheng roared, 【"Sisui Pass"】 empowered himself, and the turtle spirit saint mother's armor shone brightly on her body.

A bolt of lightning struck, and Lu Cheng spat out a mouthful of blood.

Is this a warning of an impending celestial calamity

Lu Cheng shook his head, wiped the blood from the corner of his mouth, and his eyes were firm.

Since the Qin dynasty, darkness has enveloped the night. Over a thousand years, dynasties rose and fell, with a hundred schools of thought vying for dominance! Though we have won this battle, the root of evil remains unremoved, and peace will not reign over the land and mountains! I implore Zheng sir to consider this. I shall compose seven-verse verses, gathering the best minds of the world, and pass them on to one named Song Yingxing, assisting him in writing the "Treatise on Ingenious Arts"!l kinds of fruits and martial arts skills.What's the matter with what they picked upLu Cheng immediately stopped forming his card deck into a celestial being.Emerging from the west bank of the River N...
