In just a dozen or so days, it’s naturally impossible for this deserted island to undergo a drastic transformation.
Of course, a more crucial reason is that Li Younan doesn’t have the same enthusiasm as he did during the "Alone in the Wilderness" program.
Last time, when participating in the show Alone in the Wilderness, Li Younan genuinely felt like he was on vacation, so his primary pursuit at the time was to make his life more comfortable.
But now, no matter how strong one’s inner strength is, it’s impossible to view this experience as an alternative vacation.
What’s more, there are so many people who care about him and are eagerly waiting to hear from him.
Therefore, all of Li Younan’s actions are efforts to establish contact with the outside world as soon as possible.
In this process, it seems as if he’s improving his life, but in reality, it’s work that must be done.
For example, building a house like this is mainly about coping with wind and rain, which is why it was constructed with a beam-lifting structure to have a sloped roof.
At the same time, the internal space needs to be large enough to accommodate such a workbench, which is his only means of contact with the outside world, so there is no room for error.
Even when using parts dismantled from the plane, precision is essential, and a flat table is a necessity.
As for obtaining food, most of the time, Li Younan still chooses to eat the more convenient and quick breadfruit.
But in all fairness, there aren’t many breadfruits on this small island, just two or three dozen when all mature ones are counted.
Considering the possibility that the SOS signals sent out might not be received immediately, he might enter a long-term struggle mode. Therefore, as one of the few carbohydrate sources, he must conserve them a bit.
Every two or three days, he goes to the seaside to fish to obtain the protein essential for survival, which is equally important.
Hand-cranking the radio is a very mentally consuming task; there needs to be enough energy to maintain focus.
Yesterday during the day, he successfully made the radio, and the whole process was even more challenging than Li Younan had imagined.
There weren’t many components dismantled from the plane that could actually be used.
Fortunately, there are many types of radios, and the Morse code radio that Li Younan assembled didn’t require too many precise parts; the beauty of the oscillation circuit was perfectly demonstrated at this moment.
At this moment, Li Younan had just woken up from bed, having slept for only two hours, and it was just getting light outside.
He chose to send the telegram last night, considering that late at night, there would be less electromagnetic interference from the outside, and at sea, even at night, there would be personnel on duty constantly listening to radio signals.
The signal from his radio, being simple combined with Li Younan’s radio operation skills, sent the SOS signal hundreds of kilometers away; if things went smoothly, someone should have received the SOS signal last night.
Right now, there’s another headache, which is that the battery power has run out.
Because the lithium battery from the flashlight already didn’t have much power, and without any charging equipment, after sending the SOS signal last night, he temporarily can’t use the radio.
However, it’s not without a solution.
Li Younan sat on the bed quietly thinking for a moment, his gaze falling on a pile of components featuring copper core wires and capacitors.
The only current solution is to handcraft another hand-cranked generator using these materials.
With a hand-cranked generator, he could charge the lithium battery.
To make a hand-cranked generator, the current materials were very sufficient, with magnets, copper core wires, capacitors... of course, actually doing it won’t be so smooth either.
Thinking this, Li Younan got up, went out to retrieve the remaining half of yesterday’s smoked fish, paired it with a coconut, and managed to consider it breakfast.
He then returned to the house and sat in front of his workstation again.
In front of him was a radio that wasn’t particularly exquisite, with a case made by Li Younan out of a wooden rectangular box, with a groove on the front embedded with a homemade Morse key.
The core of this key is a steel pin for operating linkages, clamped with a silver contact dismantled from a relay, because such contacts don’t need soldering, directly pressed against the pin’s base with a resilient steel strip from a seat belt, allowing the pin to function with the contact.
Without any soldering tools, this was a solution devised by Li Younan, but it didn’t affect the usage at all.
There were two holes on the left side of the box: one connecting to the antenna, which was easily resolved by dismantling galvanized steel cable from the plane; the other hole connected to headphones, also made by Li Younan himself, using rubber film, skins, aluminum foil, and copper connectors, with two copper wires, one end wrapped around the connector’s tail, the other inserted into the radio, and when placed against his ear, the Morse code’s ticking sounds were still clearly distinguishable.
Since it needed to be checked at any time, this box wasn’t covered, allowing a clear view of the oscillation circuit inside. The inductor coil was enameled wire dismantled from the plane, and the capacitor was handmade by Li Younan himself, using two slices of skin aluminum foil clamped with phenolic plastic panels from the cabin’s interior, tightened with three small bolts. Its effect wasn’t as good as soldered, but it didn’t affect the usage.
Naturally, the whole radio had no indicator lights or display screens; the only work indication was that when a button was pressed, the earphones against his ear would emit a faint hum.
