You, a tyrannical ruler, roam the heavens; you cannot understand my joy.

Remember this name: . Remember this domain name: . Good books won't lead you astray.

The next day, early in the morning.

In the mansion that Zhao Ji specially built for Lu Zuo, as soon as Lu Zuo opened his eyes, he saw the golden finger's prompt appear precisely on time.

[Missed the morning court session; internal strength +6.]

[Enchanted by beautiful women, internal strength +3.]

[Colluding with the demonic path, Demonic Heart +5.]

[Excessive indulgence in lust, bonus reward: Cultivation +1299.]

[Destroying and destroying Buddhism, extra reward: Cultivation +270000.]

[Leading a rebellion, utterly absurd, Dao Enlightenment +2.]

[Reusing a wicked concubine can bring ruin to a country; calligraphy +10, painting +10, chess +10, musical instrument skills +10.]

"It seems Madam Cai and her men have destroyed another twenty-seven temples..."

Lu Zuo thought to himself, then gave the golden finger the command: "Add all cultivation points to the Myriad Leaves Flying Flowers Stream."

[Consuming 271299 cultivation points, the Myriad Leaves Flying Flowers Flow technique has reached 271300/1000000.]

The moment the notification tone ended, an indescribable burst of vitality emerged from the deepest part of the dantian, like a seed dormant under the frozen soil of winter, suddenly breaking through the last hard shell and sprouting wildly.

The true energy within his body flowed ceaselessly, cleansing and nourishing everything it touched, as if the gentlest spring rain had soothed and cleansed his limbs and bones...

Every muscle fiber stretches and leaps with joy, radiating unprecedented vitality.

Between the livers, a cool sensation flows, as if one is in a deep mountain forest after the rain, with the freshness of grass and trees in every breath.

Lu Zuo narrowed his eyes, a mysterious perception emerging in his mind.

It's a feeling of the rhythm of life!

Within the plum blossoms in the courtyard, beneath the earth, and indeed throughout the entire world, unfolds a hazy yet vast network woven from countless breaths of life.

There seemed to be a kind of burgeoning, expansive energy in the world that was particularly kind to him.

And like weary birds returning to their nests, they gathered towards him in wisps and strands...

Lu Zuo opened his palm, his thoughts shifting slightly. Without moving his fingertips, a faint, almost invisible cyan halo naturally flowed around him, causing subtle ripples in the surrounding air.

"Ten thousand leaves flutter and flowers flow, the wood element gives rise to life..."

"The five elements within seem to be subtly beginning to form a cycle."

In the Yin-Yang School's martial arts system, the human body's internal organs correspond to the five elements. If one can master all the five elements and Yin-Yang techniques, one can create a circulation of the five energies within the body.

If the Yin-Yang incantation is added, it becomes a complete cycle of Yin-Yang and the Five Elements.

Once one reaches this stage of cultivation, severed limbs can regenerate, and injuries can heal rapidly.

Unless a vital spot is hit and the attack is fatal, it is difficult to lose one's life at the hands of another.

As for the immortality of the Underworld Emperor, it is similar to this method, but it is a kind of method that forcibly generates Yin and Yang and the Five Elements, and it is precise to the smallest details of the human body.

From Lu Zuo's perspective as a time traveler, it means that a Yin-Yang and Five Elements cycle system is constructed in every cell.

The human body inherently contains the energies of Yin and Yang and the Five Elements.

The practice of Yin-Yang techniques aims to stimulate the Yin-Yang and Five Elements, making them more intense and powerful.

Therefore, after Lu Zuo's Yin-Yang techniques based on the Wood element were improved, his Five Elements Cycle System was already being subtly established.

All that's left is to continue refining it...

Just then, a voice called out from behind. Lu Zuo turned around and saw that Jing Ni had woken up from her sleep, but her face was full of fatigue.

Yesterday, the two returned to the mansion, and after a conversation, they naturally slept together.

In fact, Lu Zuo had already guessed why Jing Ni had come when she appeared in Shangjun.

I just haven't had the time to deal with her yet...

Now that they've come to us willingly, we'll naturally accept them all, just like Li Wu and the others.

"I'm going to the Gongshu family's house later, do you want to come with me?"

Lu Zuo stood up and asked while putting on his clothes.

"No..."

Jingni weakly waved her hand, her eyes glancing at him with a mixture of resentment and allure: "I'm so tired..."

Lu Zuo shook his head and smiled: "Then you should take good care of yourself."

After saying this, he turned and left the room. He instructed the servants to prepare some tonics for Jingni before leaving and heading straight for the Gongshu family.

.......

Half an hour later...

Led by the disciples of the Gongshu family, Lu Zuo slowly walked towards the gate of the Gongshu family's workshop.

Before you even get close, a strong smell of molten metal, coke, and tung oil hits you, mixed with the smell of sulfur and saltpeter.

Behind the towering brick and stone walls, came a continuous series of metallic clanging sounds, the creaking of gears turning, and a deep mechanical hum.

"This way, Marquis Changxin, your uncle is inside."

The young man from the Gongshu family led him to the workshop gate, activated a mechanism next to the gatepost, and then stood to the side.

But then a series of clicking sounds came from the machinery, and the workshop door slowly opened.

What comes into view are more than ten furnaces burning fiercely, scattered metal parts, unfinished gears, and copper pipes of various thicknesses.

Dozens of shirtless, muscular craftsmen were busy at work.

Some people were pulling the huge bellows with all their might, while others were wielding heavy hammers, striking the red-hot metal blanks on the anvil, sparks flying everywhere.

Several other people were gathered around a partially formed mechanical beast skeleton, using complex tools to adjust the intricate gears and linkages inside.

As for Gongshu Chou, he stood in front of a huge plan beneath the mechanical beast, the table covered with cowhide drawings depicting intricate structures.

He was wearing a brown short-sleeved shirt stained with oil, and holding a bronze caliper, carefully measuring a small but intricately designed gear assembly.

Lu Zuo stepped forward, stood beside Gongshu Chou, and glanced at the blueprint. It appeared to be a mechanical beast, but the details were rough and the structure was very simple…

But this thing just happens to work, isn't that amazing?

When Lu Zuo was in Nantong, he also asked the craftsmen of Chen State to disassemble the mechanical weapons to see if they could replicate a batch.

The result was that the parts inside were extremely simple and crude, making them easy to imitate.

However, the replica mechanical beasts could not be operated, and the repeating crossbow could not fire any arrows...

What's even more terrifying is that the mechanical beast has been operating day and night, and it still hasn't broken down?

Not a single mechanical beast needs repair!

Sometimes Lu Zuo really wondered how the technology tree in the Qin Dynasty world grew.

He even thought that it wasn't impossible for the Gongshu family or the Mo family to build a spaceship out of a pile of bronze and wood someday.

"Has Master Gongshu made another new invention?"

Gongshu Chou, who was so engrossed in his conversation that he hadn't noticed Lu Zuo's arrival, only realized what was happening after hearing those words and quickly bowed in greeting.

"I was unaware of the arrival of Marquis Changxin. I apologize for failing to greet you properly."

Lu Zuo waved his hand: "We're so familiar with each other, there's no need for formalities."

"How about those custom-made Dangkang items?"

Gongshu Chou bowed and said, "Reporting to Your Excellency, it has been completed."

"So fast?"

Lu Zuo originally just came over to ask about the progress, but he didn't expect that they would actually make it for him.

"We have to thank the Marquis for this."

When this matter was mentioned, Gongshu Chou's face lit up with excitement, and even his tone became somewhat agitated.

He pointed to the furnaces in the workshop: "In the past, the most troublesome thing about the Gongshu family when making domineering mechanisms was the word 'firepower'."

"Now things are much better..."

"With the coke that the Marquis refines, all problems are solved!"

"The ferocity and duration of their firepower are simply breathtaking!"

He picked up an unfinished metal component from the table, tapped it lightly with his fingertips, and it produced a crisp echo:

"Look at this material, it heats evenly, all impurities are removed, and its toughness is even better than before."

"Key components that previously required ten days of repeated forging can now be formed in three to five days, and with even better quality!"

"That's why not only have all one hundred Dangkangs ordered by the Marquis been completed?"

"Even the production schedule for those thousand-machine repeating crossbows can be shortened by at least a year!"

He paused briefly, then added, "Oh, by the way."

"Based on the principles of the Thousand-Machine Repeating Crossbow, our Gongshu family has recently developed a new type of small Thousand-Machine Repeating Crossbow that can be held by a single person and fired continuously."

"Although its range is not as good as that of the crossbow, its power is in no way inferior."

Gongshu Chou looked at Lu Zuo, chuckled, and asked, "I wonder if Your Excellency would be interested in purchasing a batch?"

While the repeating crossbow was excellent, it was only suitable for offensive and defensive battles. This smaller repeating crossbow, however…

Isn't that a machine gun?

Lu Zuo quickly asked, "How much is one?"

"Not expensive, fifty gold coins."

Isn't this expensive?

Lu Zuo clicked his tongue slightly. If he wanted to build a ten-thousand-man repeating crossbow force, the starting capital would be 500,000 taels of gold!

This doesn't even include the vortex-feed arrow magazine...

Well, the money that was just seized from the Buddhist temple will now go into the pockets of the Gongshu family.

How much stock do you have in stock?

Gongshu Chou: "Not many. I sent 10,000 to the Lishan camp a few days ago, and there are still about 3,000 left."

"Then I'll buy three thousand first, and then order another seven thousand."

"Speaking of which..."

Lu Zuo finally couldn't contain his doubts and asked, "Mr. Gongshu, what exactly is the power source of those mechanical beasts?"

"And how does it work?"

"Oh, that's easy."

Gongshu Chou gestured with his hands as he explained.

First do this, then this, and then this, and it will run.

The explanation left Lu Zuo completely bewildered, while the craftsmen in the workshop nodded repeatedly, seemingly lost in thought, some even showing expressions of sudden realization…

……

Soon, Lu Zuo returned to the Tang Dynasty world with one hundred Dangkang rifles and three thousand repeating crossbows.

He then used the mother-child teleportation pendant to go to Yunshan County in Dongyang. He found a relatively secluded place, took out the mechanical beast and repeating crossbow from his spatial storage, and then quickly went to the county governor's mansion to call someone to come and receive them.

But after walking a short distance, an ancient-looking token came into view.

[The second talent has been triggered, granting the Barefoot Immortal's Traveling Token, allowing travel between two worlds. From: Fictional Song Dynasty.]

[Note 1: Due to differences in the flow of time and space, ten days in the fictional Song Dynasty world are equivalent to one day in the Tang Dynasty world.]

[Note 2: It can be activated after energy is injected.]

[Note 3: The world is already anchored in the Tang Dynasty. After traveling to the fictional Song Dynasty, you can stay for a maximum of 100 days before being teleported back. You can only travel back again after three days.]
