Lynn originally thought he could find an open-pit salt mine near the village.

It was already a blessing from above.

But unexpectedly, the heavens favored him once more.

A small hill of deep brown appeared in Lynn's eyes.

The scale of the hill was rounded, mostly covered by a layer of green vegetation.

Only the top had dozens of square meters of exposed coal, revealing its original appearance.

[Medium Open-pit Coal Mine]: Composed of the remains of plants and animals gradually transforming into a coal mine through complex biochemical reactions.

Standing at the edge of the open-pit coal mine, Lynn picked up a piece of dark brown rock underfoot.

The surface of the rock was glossy, with a smooth and hard texture.

[Anthracite]: Combustion material, can be used for heating, cooking, forging, etc.

Seeing the words in front of him, Lynn raised an eyebrow.

It's anthracite!

Typically, coal mines are divided into three types: lignite, bituminous coal, and anthracite.

Anthracite has the highest heat output of the three!

It can burn stably and fully without black smoke, while also generating strong heat…

If it weren't for the Ore Vein Detector.

Lynn would never have thought this was a medium-sized open-pit coal mine!

With the open-pit coal mine, mining could provide almost unlimited fuel.

Not only for heating, cooking, and forging.

The efficiency of the Salt Factory's salt production could also be significantly enhanced!

Seeing Master Lynn holding a piece of stone, reluctant to put it down, Red picked up a piece as well.

After feeling it slightly, his eyes widened in disbelief and he said.

"Master Lynn, is this... a coal mine?"

Lynn glanced at him, "Yes, a coal mine!"

Two explorations took nine days, without finding an iron mine.

But finding a medium open-pit coal mine made Lynn feel pretty good.

The next consideration was how to start mining coal!

Lynn looked at the Holographic Map; the distance from the village to the open-pit coal mine was twenty li!

Without mechanized transportation, the distance was quite far!

The location of the open-pit coal mine was downstream of the village, making it impossible to utilize the Acadia River for transport.

This means.

The mined anthracite could only be transported by cart.

The barren hill was full of rabbit holes and stones.

For the carts to pass smoothly, roads must be paved.

Three thousand mu of pea fields were not yet fully planted.

With limited labor, Lynn had to temporarily shelve the anthracite mining plan.

...

After five days away.

No abnormal situations appeared in the village.

This was due to Lynn's cultivation of their mindset and Kuisi's [Well-organized] talent ability.

The first time back at the wooden house, Lynn called on Ehrelo and Colin through Kuisi.

A Level 3 [Forging], a Level 3 [Construction].

In the wooden house.

Lynn sat on a chair, eyes fixed on the two of them.

"Gentlemen, I need you to cooperate again to build twenty carts with brakes!"

The slope of the open-pit coal mine wasn't high.

But making the carts go up safely and come down safely was challenging.

Empty carts could go up, but coming down was problematic.

After digging, coal blocks would be scattered everywhere on the mining ground.

Even with horseshoes, the draft horse's legs would be cut by coal blocks.

This is unavoidable.

Lynn was concerned that…

A cart loaded with over a thousand pounds of coal.

The cart's descent speed would be faster than the draft horse and people.

To use draft horses to go up the hill and transport anthracite, the cart's brakes must be perfected.

After explaining the cart's purpose, Ehrelo and Colin exchanged glances.

Their eyes were full of surprise.

Master Lynn had found a coal mine in the territory after being away for a few days.

Lynn said, "So, I need carts that can handle coal loads and brake on slopes."

Colin frowned deeply, and Ehrelo was also pondering something.

A little while later.

Colin spoke with regret, "I'm sorry, Master Lynn, I don't know how to make brakes…"

Ehrelo nodded in agreement.

Until Lynn used charcoal to roughly draw the outline of a braked wheel on the wall.

Colin and Ehrelo's eyes gradually lit up.

When Lynn made the ox cart frame before, he gained and integrated the knowledge of making braked carts.

Colin quickly moved to the wall, looking at the unique design, and stammered, "Master Lynn, this is…"

Lynn replied calmly, "Friction brakes."

The principle of friction brakes is simple; using things like sticks and the friction between the wheels to achieve stable deceleration.

However, the design on the wall improved on the ordinary friction brakes.

Upgraded the wooden connection between the brake pad and frame to high-quality iron connectors.

Incorporated the lever principle to adjust brake force so when descending too fast, the cart could be forcefully braked.

Finally.

Lynn added a wheel-locking device to prevent accidental rolling after parking…

After finishing drawing the cart design from memory, Lynn clapped the charcoal dust from his hands, "Do you understand now?"

Listening to Lynn, Colin and Ehrelo came to their senses.

Colin nodded repeatedly, "Master Lynn, no problem. If Ehrelo collaborates with me, we can make such carts!"

Ehrelo responded, "Yes, Master Lynn."

Lynn nodded in satisfaction, "I wish to see these twenty carts after the summer plowing!"

In the discussions between Colin and Ehrelo, the two left Lynn's wooden house.

Neither Colin's carpenter's house nor Ehrelo's Blacksmith Shop requires them to labor.

Their task is to relentlessly create the labor tools needed by the village.

Picking up two baskets of herbs, Lynn headed towards the well.

Amid the curious gazes of some villagers, he began washing the herbs.

Herbs collected back, if to be used as medicine, need several processing steps.

Cleaning, sorting, drying, crushing, packing, and storage.

Once cleaned, Lynn found some flat baskets to naturally sun-dry the sorted herbs and wick away moisture.

...

Gradually gaining experience, Lynn's mind was enriched with knowledge about [medicine]

Until evening time.

Lynn sat in front of the kitchen stove.

On the stove, a Pottery Pot was continuously boiling.

A cool aroma entered Lynn's nose and mouth through the steam.

Lynn felt an inexplicable comfort!

Boiling mint in the Pottery Pot for twenty minutes, he then poured the Mint Soup into a bowl.

The fresh fragrance and herbal aroma became even more intense.

Lynn looked at it, and a string of words emerged.

[Mint Soup]: Non-toxic, made by boiling mint, can be used to relieve symptoms such as fever, headache, and sore throat caused by colds.

Lynn nodded in satisfaction and took a sip.

The taste was slightly sweet with a faint coolness.

Pouring the Mint Soup from the Pottery Pot into a large pot, he instructed the cook to distribute these concoctions to the villagers.

Lynn continued brewing more remedies.
