Next, Lin Yu'an stacked four spruce logs neatly on the inside of this row of wooden stakes, forming a solid and aesthetically pleasing log wall about forty centiters off the ground.
Then, he constructed the sa structure on the other side of the shelter, in the sa manner, before starting to process the edges of the waterproof tarp.
He stretched the lower hem of the waterproof tarp outward, just covering the tops of the two spruce log walls.
Imdiately, he used tripwire and carved ground nails, employing the truck driver's tightening technique to pull each attachnt point of the waterproof tarp taut, like a drum surface.
An extrely complete A-fra shelter with a solid log wall at the base was built in just over two hours.
But this wasn't the end; the most crucial heating system was yet to be completed.
Lin Yu'an said to the cara, "In the nights of Labrador, a good fire source is more important than a good roof."
He ca to a spot about one and a half ters in front of the opening of the shelter, and cleared all the vegetation and humus layer from the ground.
Exposing the moist soil beneath, he ford a fire pit about one ter long and half a ter wide.
Then, he went into the woods and sawed several thicker, dry spruce logs.
He stacked these wet logs outside the fire pit, parallel to the opening of the shelter, to create a heat-reflective wall about half a ter high.
"This design is the most efficient radiant heat heating system."
"The rock wall behind the shelter is the first reflective wall, and the wooden wall we just built is the second."
"When I ignite the long fire pile in the middle, its heat will be repeatedly reflected by these two walls, continuously funneling warmth into the place where I sleep, creating a warm radiant heat channel."
After doing all this, he began to perfect the interior by laying a thick layer of spruce branches on the shelter floor, forming an insulating layer about twenty centiters thick, serving as a mattress.
He stuffed finer branches and leaves into the backend of the A-fra, sealing it completely.
By the ti he finished all this, night had completely fallen, and he finally burrowed into the small temporary shelter that was enclosed on three sides and open on one side.
Then, using the magnesium rod and birch bark, he ignited the long fire pile, and the flas rose, bathing the entire interior of the shelter in a warm orange glow.
He could clearly feel waves of heat coming simultaneously from the fire pile in front and the rock wall behind, enveloping him.
Subsequently, Lin Yu'an unfolded his top-tier Western hiking sleeping bag and crawled inside, as the 850-fill goose down quickly locked in his body heat.
He lay in the darkness, watching the flas flicker ahead, listening to the howling sea wind outside, yet his mind was calr than ever.
The journey to the Frozen Throne has just begun!
————————
After a warm and stable first night, Lin Yu'an was awakened by the clear calls of seagulls in the distance.
He opened his eyes and the first ray of morning light shone through the opening of the A-fra, dyeing the inside of the shelter with a soft golden hue.
The long fire pile in front had gone out, leaving only warm ashes, but the sleeping bag still maintained a relatively comfortable temperature, not feeling the outdoor chill at all.
He unzipped the sleeping bag and walked out of the shelter, taking a deep breath of the cold yet fresh air.
He turned on the GoPro on his chest, speaking to the cara, "Good morning, everyone. It's six thirty in the morning, the first light in Labrador."
"I slept well last night; the effect of this temporary shelter exceeded my expectations."
"Today, our top priority is to solve the food problem, and to conduct a more detailed exploration of this territory."
"The coastline especially needs focused exploration. On this coastline, the most generous hunting grounds are the intertidal zones left by receding tides."
He didn't head out imdiately and instead first went to the shore, carefully observing the water-stained marks on the rocks, and then looked up at the position of the moon.
"The most important thing to survive on the coast is to understand the tides."
He proceeded with educational explanation to the cara, "I checked the data before I ca; the Labrador Coast has a semi-diurnal tide, aning there are two high tides and two low tides each day."
"Each tidal cycle lasts about 12 hours and 25 minutes, and now the position of the moon and the height of the tide line tell that this morning's lowest tide will occur around nine-thirty."
"Both the ebb and flow of the tides take about six hours each. I can't wait until the last mont of the lowest tide to head down, nor linger after the tide starts rising."
"And about one to two hours before and after the lowest tide—that is from eight thirty to about ten thirty—is when the tides are most stable, and the exposed mudflat area is largest."
"So, the safest strategy is to enter the intertidal zone an hour before the lowest tide and depart within an hour after the lowest tide."
"This ans that approximately two hours is the golden window for safe exploration of the intertidal zone."
"If I miss it, once the tide starts rapidly rising, it becos very dangerous, so I must seize this opportunity!"
During the more than two hours waiting for the tide to recede, Lin Yu'an didn't remain idle either.
He first went to the freshwater lake and filled his MSR stainless steel pot with clean drinking water, then set it over the fire to boil.
Then, he began to organize his gathering equipnt for the day, taking out the compression storage bag of his top-tier Western hiking sleeping bag from his backpack.
