In addition to these electric protective nets, some life-related electrical appliances also appeared.

[Electric Lamp: Can emit a weak yellow light, illuminating a small room. Requires Iron*1, Glass*2, Copper Block*1]

[Electric Grill: Grill food without smoke, healthier! Requires 10 iron blocks and 2 copper blocks]

Range hood: This appliance extracts cooking fumes and exhausts them from the tree house. A must-have for the kitchen! Requires 10 Iron Blocks and 2 Copper Blocks.

[Electric water pump: Connect to the water source and automatically draw water after power is turned on. Need to be connected to the pipeline for use. Requires 5 iron blocks and 2 copper blocks]

[Electric water heater: can heat water for showering, needs to be connected to a pipe. Requires 5 iron blocks and 2 copper blocks]

[Pipeline: The pipe connecting the water pump can withstand water temperatures of 0-100 degrees. Pipe*1 requires iron block*1]

This is possible, this is really possible!

With these, his tree house really feels like a home!

Not to mention the electric oven and range hood, the electric water pump and electric water heater at the back were enough to make him smile.

He had always felt that his bathroom was too basic. He had to fetch water himself, and he usually went outside to relieve himself. There was no water heater. The water temperature was just right when the weather was hot, but now it was so cold that he had to boil water for every shower.

It’s too troublesome and time-consuming, and it’s not safe to go out and solve the problem.

And now, electric water pumps can be used to pump water!

The power system must be established.

This time, it really is a complete transformation from the inside out! Most importantly, these appliances don't require a lot of copper. The electrical grids and pipes, which require the most, don't require copper!

The copper blocks in his hand can meet the needs of many people!

Just do it.

The first is the generator.

Since he has the coal mine, it is naturally impossible for him to use a hand-cranked generator.

However, the introduction of coal generators says that they will produce exhaust gas, heat and noise, so it is best not to place coal generators inside a tree house.

Xu Xin thought about it and felt that it was not appropriate to leave it outside.

It is not safe outside the tree house. Even though it is protected by plant hearts, there will still be natural disasters, behemoths and other factors that he cannot predict. It is really inappropriate to place a generator that provides electricity outside the tree house.

You must know that the three major elements of the Doomsday Fortress: food, energy, and weapons, must all be inside the fortress. Once attacked, you can defend the fortress to the death. As long as the fortress is not destroyed, there will not be any major losses.

Therefore, things like generators should be placed inside the tree house.

But the exhaust, the heat, the noise...

Xu Xin thought of the newly expanded space on the first and second floors.

Those spaces are completely separated from the third-floor living area and the fourth-floor planting area where he lives, and are far enough away that there is no need to worry about them affecting each other.

I chose the new space in the tree house on the second floor! It also happens to be home to various workshops and workbenches, giving it a real factory vibe.

Moreover, there is no third floor above the newly appeared second floor, which makes it more convenient for the discharge of exhaust gas, after all, exhaust ports can be opened on it.

Xu Xin immediately went down to the second floor and pushed open the door to the new space.

This newly appeared space of 100 square meters seems to be a little bigger than the last time I came here.

According to the introduction of the banyan tree, the crown of this banyan tree will continue to grow!

However, this presents a problem.

As the banyan tree continues to grow, will the positions of the items placed in the tree house change?

Xu Xin observed carefully and came to a conclusion through the patterns on the floor and walls: the formed floor will not change, will not stretch as a whole, but will continue to grow from the edges to expand its area.

In other words, if he places a coal generator next to the window and wants to use the window to discharge exhaust gas, as the banyan tree grows, the position of the generator will not change, but the window will be farther and farther away from the generator!

Hmm...it's a bit troublesome.

He could make a hole in the ceiling to let in air, but that would involve issues like rainwater...

Let's do this first. Anyway, the tree house is not growing very fast. It looks like it may not grow more than a few centimeters a day. At worst, we can just adjust it later.

After making the decision, Xu Xin immediately made a coal-fired generator.

【Please select a placement location.】

He directly chose a location at the edge of the second-floor tree house, next to the window for exhaust, which was the farthest from his living area.

"Bang!" With a loud noise, a coal generator three meters wide and one and a half meters high appeared beside the window.

Xu Xin walked forward to observe.

The entire generator is made of iron, showing a bright metallic color, and the sharp-edged structure looks really technological. In front of the generator, there is a round iron cover with a handle on it.

He pulled the handle open, revealing a furnace-like combustion chamber.

It seems that all that needs to be done is to put coal in it.

Xu Xin did not throw coal directly into it. He had not yet connected the wires and the battery. Starting it would only be a waste of coal.

He thought about it and built a few more walls around it, enclosing the entire coal generator into a small room. Otherwise, the exhaust gas generated during power generation would fill the whole room. In this way, there was only one exhaust outlet, the window, and there was no problem.

Let's call this small room the power room.

Next is the battery. With the battery, the generator can generate and store electricity.
