The forging workshop in the shelter became the absolute core of the entire settlement over the next month.

Lin Feng practically lived and worked here. He personally drew countless blueprints, from the overall structure of the generator to the dimensions of each gear and the number of turns of each coil, all accurate to the millimeter level.

He instructed Li Xiangbin and several women to begin forging the generator's casing, rotor, and stator using all the metal reserves in the shelter. The clanging of the hammer never stopped from morning till night.

The most crucial step is winding the coil. This is an extremely delicate and tedious task.

Su Wanqing and Qin Lan volunteered for the task. Together with several of the most meticulous women, they carefully and tightly wound the copper wires, each wrapped with an insulating layer, onto the forged iron core.

Their fingers were worn raw, their eyes were bloodshot, but not one of them complained. Because they knew they were weaving the future of this world with their own hands.

Pang Dahai was also conscripted.

His chubby hands, capable of tossing food and carving patterns with incredible dexterity, proved far more effective than Li Xiangbin's brute force when performing delicate welding tasks.

He was responsible for using a high-temperature spray gun (a simple tool that Lin Feng made using combustible gas and mineral crystals) to connect the various parts together.

Lin Feng, on the other hand, was the chief designer and the soul of the entire project.

He was like a king inspecting his kingdom, constantly checking the progress and quality of every step and solving one unexpected technical problem after another.

His vast knowledge base allowed him to easily spot even the smallest flaws.

A month later, a huge and rugged "permanent magnet synchronous generator" full of steampunk style was finally born thanks to the concerted efforts of everyone.

It stands silently in the center of the forging workshop, like a sleeping steel behemoth.

Black magnesia ore is skillfully inlaid on the massive rotor, shimmering with a deep, eerie light. Coils made of red copper and wood cores densely cover the stator, like the neural network of a behemoth. Every solder joint, every screw, embodies the hard work and sweat of everyone involved.

Next up is wind power.

Lin Feng chose the huge wind gap to the north of the shelter.

The wind there howls like ghosts and wolves all year round, so fierce that it can make boulders roll.

The construction of windmills is an equally massive undertaking.

They felled the tallest and toughest iron birch trees in the forest, and Lin Feng personally designed and shaved them into four enormous blades, each ten meters long and designed according to aerodynamic principles. They then used most of the remaining steel from the shelter to forge an indestructible iron tower that was twenty meters tall.

How to hoist the generator, weighing several tons and with huge blades, onto a 20-meter-high tower became a huge challenge.

In the end, Lin Feng, using levers, pulley systems, and the combined strength of the gold miners and everyone else, spent two whole days and, after numerous perilous attempts, successfully installed this behemoth into its designated location.

When the last blade was secured, the enormous, cross-shaped windmill stood tall in the wind, blocking out the sky. Everyone stopped what they were doing and looked up at this magnificent creation, a testament to the harmony between humanity and nature, their hearts filled with indescribable pride and awe.

Electricity was now available. However, wind was unpredictable, sometimes strong and sometimes weak. To obtain a stable and continuous power supply, energy storage devices—batteries—were necessary.

Lin Feng turned his gaze to the "Thunder Stone" recorded in his knowledge base.

This is an extremely rare crystal that can only be formed in special quartz veins in areas with frequent thunderstorms and where lightning strikes year after year.

It can lock in and release huge charges at the molecular level.

This time, Lin Feng didn't bring the main force, only Li Xiangbin and Zhui Feng Zhu Yue. This was because the Thunderstone's source was located in a forbidden zone known as the "Thunder Swamp," a death zone.

It was a swamp shrouded in thunderclouds year-round, where blue-purple arcs of electricity would occasionally burst forth without warning from the black mud.

The air was filled with a strong smell of ozone; any living thing that stepped into it could be turned into charred remains by a lightning bolt that fell from the sky in the next second.

Lin Feng rode on the back of Zhui Feng, flying low beneath the thunderclouds. His eyes flashed with faint electric light as he searched for the area where lightning struck most densely.

Finally, in the center of a charred, completely vitrified ground, he spotted a faint blue light.

"That's it!"

He directed the descent of the wind-chasing device, while he himself donned a heavy, insulating suit specially made from the sap of the rubber tree and cautiously approached.

It was a peculiar crystal, only the size of a human head, translucent and a deep blue color, with what appeared to be countless electric snakes writhing inside. It was the Thunderstone!

Lin Feng could sense that this small stone contained terrifying electrical energy enough to power the entire shelter for several days.

He carefully mined it using specially made insulated tools and placed it in a lead box made of the same insulating material.

In the following days, he risked his life to find three more similar thunderstones.

Back at the shelter, Lin Feng immediately began constructing the "super battery pack".

He dug a huge, secluded chamber underground. Then he fired four enormous insulating pools out of clay, placed four thunderstones in each, and poured in a mineral salt solution that he had concocted to promote a stable flow of electrical charge.

The main cable leading from the wind turbine is buried deep underground, passing through thick layers of rock, and finally connects to this "battery pack".

A large and stable power supply network is beginning to take shape.

The final challenge is the terminal that illuminates the light – the light bulb.

Glass is very easy to obtain.

The lamp holder and wire connection can be made using copper wood and scraps.

Most importantly, it's the filament. It must be able to withstand high temperatures without melting and emit light stably.

Lin Feng once again demonstrated his god-like knowledge.

He led his men to a volcanic area and found a strange creature called the "Fire Rock Spider" that lived in the crevices of lava. The silk spun by this spider was incredibly strong and had an alarmingly high melting point, making it the perfect material for light bulb filaments.

After countless failures, with the help of the vast ocean, the first alien incandescent lamp, though ugly, was structurally complete and embodied the hard work of countless people.

It was carefully installed at the top of a specially erected wooden pole in the central square of the shelter. Two black wires connected from the light fixture, ran down the pole, and disappeared into the ground, becoming part of the shelter's overall electrical system.

Everyone knows that tonight will be the moment to witness a miracle.
