In the live broadcast room, when the audience heard Lin Feng's words, the screen was full of question marks.

“？？？”

"That's tall, did I hear me right?

"Tap water, exquisite!"

"Master Feng is really an infrastructure maniac!"

"So the question is, where do the faucets come from?"

While watching the barrage, Lin Feng stood on the high ground to build a collection fan, and explained with a smile: "Faucet, we can use bamboo pipes instead." Then, in the pipeline, install a simple filtration system, and when you don't use it, you can find something to seal the nozzle. ”

"The cistern is open-air and will be frequented by mosquitoes and birds, so a filtration system must be installed, otherwise I can guarantee that the water you drink will definitely smell of bird droppings. ”

Ten minutes later, all three collection fans on the reservoir were set up.

The next step is to mud up.

Mudding can fill the gaps between tree branches, so that it can better collect rainwater and ensure collection efficiency.

"Before mudding, it's a good idea to layer the fan with a layer of palm or some of the larger shrub blades to make the fan smoother. ”

With that, he jumped off the heights, went into the woods, and brought back a lot of palm leaves.

The collection fan was built on only three sides.

The extra outlet can be used as a water level observation window.

The specific structure is a layer of palm and a layer of mud.

It has two floors.

One side has an area of about 1.5 square meters, and it is rectangular and spreads outward.

When it came to the mud, Lin Feng needed to climb up to the high ground next to the collection tower first, and then lean forward, his belly against the observation window.

Go to the sides first, then to the side farthest from you.

When he was working, in order not to let the live broadcast room be cold, he began to popularize the history of the rainwater collection tower to the audience.

"The rainwater harvesting tower is the earliest known water storage device of mankind. On tropical islands where fresh water is scarce, the indigenous people of primitive tribes call it 'the waterhole of life'. ”

"Until now, some indigenous people in the Pacific South Island have used this method to collect rainwater to pray for good weather throughout the year. ”

"Although the collection tower has been reduced from a utility to a decoration for blessings, and has withdrawn from the stage of history, its role is still there. ”

"For survivors, the waterhole of life is your hope to live. ”

Talking and doing, progress is fast.

After a while, the fans on all three sides were coated with two layers of fine clay and became flat.

Then, while drying the yellow mud, Lin Feng began to make an automatic flow device.

This seemingly tall device, in layman's terms, is actually a hollow bamboo pipe, add some charcoal to it, and then find a bamboo tube to seal the water outlet.

When you need to catch water, remove the bamboo tube, and when you don't need it, cover it.

"The outlet pipe doesn't have to be bamboo, any hollow tubular item is fine, such as discarded plastic pipes, bamboo pipes, hollow thin tree trunks, etc. ”

When I built the triangular house before, there were a lot of thin bamboos that were idle.

Over time, these thin bamboos have long since changed color.

Lin Feng chose a bamboo with fewer knots, took a few red-hot charcoal fires, threw them in, and kept blowing into the bamboo pipe.

At this time, the camera gives a close-up of the inside of the bamboo pipe.

I saw that the charcoal fire in the depths flickered and dimmed, and it didn't take long for wisps of green smoke to float out of it.

"666, this big smoking gun!"

"Sexy Streamer, Smoking Online!"

"Master Feng, the old man is still short of a boy here, with a monthly salary of 3,000, including room and board, can you come?"

“233333”

Soon, as time passed, the charcoal fire finally burned an irregular hole in the bamboo and fell.

The ignition point of dried bamboo is about 300 degrees, and it is perfect to punch holes with charcoal.

The only thing to pay attention to is that the charcoal fire should always be kept away from the inner wall of the bamboo pipe, so as not to burn the pipe.

After about ten minutes, the green smoke gradually thickened, and the two bamboo joints of the bamboo pipe were all opened.

Then, Lin Feng took a piece of cold charcoal of the right size and stuck it on the top of the outlet pipe, leaving a gap between his fingers.

The next step is to install it, just insert the end with charcoal into a bottom corner of the bottom of the cistern, and extend the outlet of the water pipe to the mud wall below.

After the planning was completed, Lin Feng used an axe and a stone knife to smash a hole in the corner of the reservoir, inserted one end of the bamboo pipe into it, took the mud and sealed it, and then used a slightly larger diameter bamboo to fasten the water outlet to act as a water valve.

"After the water pipes are ready, there is still one step away from completion, which is to fire the bottom and walls of the pool. ”

"This firing method is the same as burning pottery over a bonfire. Therefore, the heating may not be very uniform, and it cannot be formed at one time, at least several times. ”

At this time, the time was close to noon, and the temperature on the island began to rise, and in only two or three hours, most of the clay was dry, but it could not be fired immediately, and it had to be dried for a day or two.

In the afternoon, Lin Feng made some chicken food, watered the vegetable garden, lay down in the hut to make up for sleep, and didn't get up until three o'clock.

For dinner, it was still chicken and cassava.

In addition to coconut, there is also sugar cane for dessert.

The smoked turkey meat with cane juice has a unique flavor and is no worse than honey.

Before going to bed, Lin Feng collected a large number of dead branches and leaves in the jungle, spread them on a dry clearing in front of the camp, and scattered them with wooden sticks.

Because of the frequent rain in the past few days, even the deeply buried branches and leaves are a little damp.

In order to ensure the firing effect, it is best to air dry it one day in advance.

Nothing was said all night.

The next morning, the weather was clear.

After breakfast, Lin Feng opened the live broadcast room as soon as possible.

"Good morning, everyone. Today, we're going to burn the cistern. ”

When Lin Feng walked towards the water tower, a line of white subtitles appeared on the screen: "Desert Island Survival, day.50." ”

……

After a day and a night of air drying, the clay in the pool has been completely dried.

Lin Feng took a part of the scattered branches and leaves, poured them into the pool, and lit them with tinder.

Soon, smoke rose and the fire grew stronger.

"Worship Fire Maple is going online?"

"The Altar of Storm is officially opened~!"

"Full of rituals, 23333"

"Will this work?

Half an hour later, a furnace was finished.

The color of the pond changed dramatically, and the clay changed from yellow to iron blue.

Lin Feng knocked on the bottom of the pool with his hand, feeling that it was not enough, so he burned another stove.

"It's not completely hardened, and it will have to be burned at least two or three more times. ”

"That's the disadvantage of clay, if it's high-quality concrete mixed with lime, you don't need to go through the hassle, just wait for it to dry, and it's super waterproof. ”

"The fired clay can be used perfectly, but it always needs to be repaired. Otherwise, over time, the appearance will crumble. ”

Soon, two hours passed, Lin Feng burned it a total of four times, until he thought he could fill the water, he cleaned the wood ashes inside, and then carried the clay pot, poured three large pots of water next to the canal, and poured it into the cistern.

Didn't leak.

It's just that the water is a little muddy, there are a lot of impurities, and there is a thick layer of grass ash floating on it.

Immediately afterwards, when the audience questioned whether the collection tower could not successfully produce water, Lin Feng smiled, without saying a word, and directly pulled out the bamboo water valve.

One second, two seconds, three seconds!

After waiting for a few seconds, suddenly a slightly turbid clear stream slowly flowed out of the bamboo pipe......
