The Ultimate Live Superstar

A simple bark,

Can you play so many tricks?

Just a little makeover.

Just turned into a blower?

This is too bullshit!

I saw Lu Yu's actions.

There was an instant uproar in the live broadcast room, all kinds of gifts appeared one after another, and it took a long time to subside!

but.

Amidst the admiration, many water friends also said:

This kind of blower with built-in blades is too inconvenient.

It is only possible to work by constantly rubbing it with your hands.

If I use this guy to heat up the charcoal fire, I'm afraid I can't do it if I'm not single for 50 years, right?

Most importantly, it's tiring to look at!

Copper smelting is a big project, when will this turn to the end?

Faced with doubts from some viewers.

Lu Yu smiled knowingly.

Please don't worry:

"Everyone, this is just a half-finished product, don't be impatient, then look down-"

talking.

He turned around and found a few branches of different lengths.

A small wooden frame in the shape of a "door" was built with bark rope.

placed above the blower.

Then, he took out the spindle he had made while weaving before.

"Remember this spindle?"

"When I was building the weaving machine, I said that in addition to turning silk threads into twine, the spindle could also be used as a bow drill."

"If it is applied to the blower, the problems that everyone cares about will naturally be solved."

Bow drills, as the name suggests, are drills with bows.

Mostly used for drilling wood for fire.

This method of making fire should be one of the most convenient and quick methods of drilling wood to make fire.

save time and energy.

Incredibly efficient.

Much more powerful than a hand drill.

In addition, in other respects, bow drills can perfectly replace manpower.

An automatic blower is one of them.

talking room.

Lu Yu held a spindle.

Remove the circular stone plate below.

I randomly found a bark rope and tied it to both ends and transformed it into a wooden bow.

Next, wrap the tree rope bowstring around the fan's drill pipe.

It was fixed on a small wooden frame together.

As such.

Just hold one end of the bow drill with your hand and keep pushing and pulling.

The fan blades of the blower will naturally follow!

Not only the wind is persistently strong.

The most important thing is that this is much less labor-intensive than simply rubbing it with your hands!

After it was done, Lu Yu didn't say much, just showed it to the audience on the spot!

on the screen.

As the bowstring is retracted and released.

The fan blades in the casing sometimes turn forward and sometimes reverse.

In an instant.

The whirring sound of the wind came out from the air outlet, and it didn't take a moment to blow the charcoal fire!

see this picture.

The audience suddenly lit up and left messages in the barrage:

"Fuck! Wonderful!"

"This blower is invincible!"

"So ingenious!"

"666666666"

"The anchor's manual ability is really strong!"

"This wind is comparable to that of a five-speed electric fan!"

"Do you know so much upstairs? Have you ever lived?"

"Hahahahahaha!"

...

soon.

After a wave of gifts, Lu Yu simply thanked him a few words:

"Thank you all for the gifts."

"Actually, it's just a very simple automatic blower, and it's not difficult to make at all."

"The main structure, nothing more than the fan blades and the shell, are all materials that are usually available at your fingertips."

"The principle is even more simple and clear, and any normal person can imagine it."

"However, in order to perfectly apply simple principles to daily production and life, in addition to being good at discovering, we must also dare to try."

"Because in the final analysis, it is the repeated attempts that have allowed human civilization to go from being poor and in vain to where it is today."

"How's it going, guys? Isn't this blower interesting?"

More than interesting.

Simply too TM show!

The simple principle that no one knows, plus a few inconspicuous things to piece together everything, can play so many tricks.

It's not okay to disagree!

This scene almost perfectly interprets the unique charm of primitive existence——

Create your own world bit by bit using the materials you can get your hands on!

...

two hours later.

Lu Yu put the finished blower aside.

Walking to the charcoal kiln, through the ventilation holes below, I leaned over to observe the fire inside.

At this point, the fire above had completely spread to the bottom of the kiln.

The firewood below was flushed red.

"Everyone, it's almost the same as burning like this..."

Deducting a large piece of clay from the bamboo basket, Lu Yu continued:

"The next step, what we have to do is to plug all the ventilation holes with mud."

"Including the opening above the kiln roof."

"The purpose of this is to slow down the burning speed of the charcoal and let it be completely carbonized. At that time, as long as all the volatile gas overflows, it will be done."

"The whole process may take a while, so we have to wait for a while."

Taking advantage of this time, Lu Yu ate something casually to replenish his energy.

Then, he started the stove again.

A fire was rearranged.

And take out most of the remaining mud.

around the fire.

Circle by circle, a small cylindrical furnace was built.

"Someone asked in the barrage, why do you need to make another furnace when you have an earth kiln?"

Looking at the barrage, Lu Yu explained:

"It's actually very simple. The bigger the kiln, the better."

"For metal smelting, a small furnace is easier to concentrate the temperature than an earth kiln. Secondly, because our materials are limited, if an earth kiln is used, more charcoal will be wasted, so it is necessary to build a small furnace separately."

talking room.

Lu Yu first smoothed the edge of the furnace with his hands.

Then a moderately sized charcoal outlet and air inlet were opened at the bottom.

The role of the air intake is obvious.

Just to connect the blower to the duct!

The role of the charcoal outlet is also well understood.

With it.

After the refining is completed, the copper material reduced by charcoal fire and high temperature can be easily scraped out of the furnace.

The function of the opening line of the charcoal kiln is similar.

...

Live stream here.

With the blower, furnace, mineral powder and charcoal, the preparatory work basically came to an end.

Next.

As soon as the charcoal comes out of the oven.

You can throw the ore powder into the furnace.

Covered with charcoal smelting.

By the time.

After continuous refining at high temperature, the copper contained in the mineral powder will naturally be gradually reduced and become copper material.

After that, just melt the copper stock into liquid copper.

Pour into molds.

You can turn it into the shape you want!

Like an axe blade, a knife blade.

Even arrowheads are no longer a problem.

...

Time flies.

In the blink of an eye, it was two o'clock in the afternoon.

While waiting for the charcoal to come out.

Lu Yu was not idle either.

He has been chatting with the audience without a word.

It wasn't until the green smoke at the mouth of the charcoal kiln stopped volatilizing that he stood up and walked over to check.

to the kiln.

He first touched the temperature of the kiln wall with his hand.

Then, I checked the fire on the top of the kiln again.

After a while he said:

"Friends, it should be almost burned."

"Stop talking, let's open it up and see what's going on inside—"
