Survival in the Banna Rainforest, night of the ninth day.
Inside the shelter, faint snores arose.
On a nearby earthen mound, a huge dark shadow slowly protruded from the bushes, gazing at the shelter for several minutes before a soft rustling sound of digging reached the air.
The snoring stopped.
Bi Fang opened his eyes, stared blankly at the canopy above, sat up, scratched his hair, picked up a dry stick that had been whittled into a fish-scale shape and dipped in oil, and lit it before stepping outside the fence.
Under the glow of the fire, the sound of digging abruptly ceased.
After gazing dumbfounded for a few minutes, Bi Fang sleepily reinstated the bamboo gate and threw the torch into the campfire.
He went back to sleep.
…
Morning of the tenth day.
Sunlight shone in from outside the door.
Bi Fang yawned, chewed on lemongrass mixed with charcoal, brushed his teeth with a tree stick for a while, and washed his face with clean water before concluding his morning hygiene routine.
After dealing with personal hygiene and filling the holes with charcoal ash and soil, Bi Fang started his live stream.
“Good morning, guys.”
[Boss Fang, good morning!]
[Why aren’t there any sisters, wuwuwu]
[Shivering cold, when will we women finally stand up]
[Did the Water Monitors attack at night?]
[Old Fang seems to have slept quite well? Did the Water Monitor leave?]
“It didn’t leave,” said Bi Fang, signaling the drone to follow behind him as he moved to the spot opposite the doorway.
There used to be a small hillock covered in bushes, with a stream and a big river in front and a slope with bushes behind—the shelter could be considered perched by the mountain and water.
But now, the small hillock had undergone a complete transformation, a pitch-black cave appeared at the bottom of the mound, and the dug-out earth was piled in a circle at the entrance of the cave, resembling a trench.
“It’s inside there right now.”
This was…
Zhou Weisheng stood up straight, looking at the scene with some surprise.
Zhou Weisheng had woken up early just to watch the live broadcast because he wanted to get a deeper understanding of the state of the Water Monitors within his own protected area.
Normally, his team would re
“Once the air starts moving and the speed is fast enough, we have ample oxygen to aid combustion, which increases both the efficiency and the temperature of the burn, essentially acting like a natural bellows.”
By harnessing the principle of hot air rising, the furnace expels hot flue gases from an outlet at the top while fresh, cool air is drawn in from the inlet, increasing the oxygen needed for the fuel to combust fully, and thus intensifying the flames.
This is the principle of the high furnace.
Iron smelting in a high furnace sounds complex, but it’s literally iron smelted in a high furnace.
Throughout history, a major constraint on materials has been the combustion temperature and furnaces capable of withstanding high temperatures.
The audience had an epiphany.
[Holy crap, I get it now!]
[Damn, is it really that scientific? I always thought Boss Fang hailed from a mystical world, dog’s head.]
[You think I’m science, but I’m really mysticism, ha!]
[There’s always someone dressed in the trappings of science, showing us magic.]
“High-rise buildings are the same. A fire in the lower floors creates hot air that moves upward through passages, continuously accumulating hot gases at the top, and as a result, the fire spreads to the top floors through air convection.”
“So in case of a fire, never run upwards; you must always head downwards.”
Bi Fang dug a pit large enough to accommodate half his body and started to build a stove out of clay.
[Is iron smelting with iron bacteria really reliable? It feels like Magneto pulling iron out of someone’s body.]
[It does sound a bit esoteric, but to say it won’t work, I’d bet fifty cents Fang will slap me in the face. Clown.]
“There are no issues, whether from a theoretical or practical standpoint, it is entirely possible to succeed.”
Bi Fang piled a large clump of clay on the ground, spreading it out in the pit and plastering a layer around the edges as well.
“Iron bacteria can oxidize ferrous iron to ferric iron and extract energy in the process, oxidizing ferrous compounds in water and causing them to form ferric hydroxide precipitates.”
“The sediment accumulates around the bacteria, generating vast amounts of brown sludge, leading to pitting and tubercles in equipment and piping. Often, the brown rust we see inside pipes is this stuff.”
“It’s also because of this that they can oxidize dissolved ferrous hydroxide and ferrous carbonate in the water to form ferric hydroxide deposits, concentrating and accumulating iron in the environment. Many scientists also believe they might play a role in the natural formation of limonite.”
“The ultimate ferric hydroxide can indeed be used for iron smelting!”
