Gabriel had initially considered lighting them one by one.
But after challenging it several times in a row, it realized that the scattered sound-frequency bands in the air were not as numerous as imagined. There simply were not enough to light all one hundred and eight lamps in batches.
Since lighting them in batches was impossible, what should it do instead?
Gabriel soon discovered that among the sound-frequency bands in the air were some peculiar "noises," and these noises contained strange sound-frequency bands.
If it used these bands in combination, it could possibly produce the sonic meanings of "complete," "whole," and "entire."
Gabriel was not stupid. By this point, it understood the true rules of this "Beacon Challenge."
Lighting the lamps one by one was unrealistic. It could only use the "noises" to gather certain keywords, ultimately combining sound frequencies such as "light up together," "all shine," and "the whole illuminates."
Making every lamp in the entire corridor light up at once.
That was the true method of clearing the Beacon Challenge, as well as hidden information not recorded in the challenge rules.
After discovering this, Gabriel began trying again.
However, during its attempts, it found more clues. The "noises" did not remain forever. Some might exist for only a few seconds before vanishing.
And to form sound frequencies like "complete," a single noise was not enough. It needed to gather a large number of noises.
It was even possible that it had to swallow every single noise into its stomach before it could find the complete arrangement and combination.
Last time, Gabriel had missed several noises. At the final moment, it simply could not piece together a complete sound frequency, and could only reluctantly declare failure.
This time, Gabriel had learned its lesson from before.
