The manufacturing technology behind supergiant war armor was extraordinarily complex. Due to their immense size, even the forging of special metals and the transmission of energy posed enormous problems.
If cutting-edge weapons such as space shuttles, aircraft carriers, and intercontinental missiles once demonstrated a nation's strength, then supergiant war armor demonstrated the strength of human civilization as a whole.
Even with the combined efforts of all humanity, and the Salvation Army's tremendous support, only thirty-three supergiant war armors had been built worldwide.
It could be said that every supergiant war armor was the crystallization of human civilization's painstaking efforts, the pinnacle of humanity's survival and reproduction on Earth.
For that very reason, these weapons of war were all priceless treasures. Each had its own unique signal frequency and was equipped with a signal transmitter tens of thousands of times more reliable than an aircraft's black box, allowing the fastest possible rescue when endangered or even missing.
What Shen Feng held in his hand were several such signal trackers.
He could not help feeling excited. Drawing a deep breath, he pressed the button and turned on the signal tracker's screen.
Light flickered, and a simple, clear world map appeared on the screen, followed by dozens of flashing points.
This was still a map of the world from before it had been completely submerged by the sea, and Shen Feng felt a surge of familiarity.
Thirty-three flashing points were scattered across the globe. Shen Feng saw one near San Francisco, clearly the wreckage of the Oglala Crazy Horse he had encountered earlier.
In a stretch of sea somewhat farther from San Francisco, another faint point was also blinking.
If he was not mistaken, that sea area was the Mist Sea he had visited before. The flashing point was most likely the supergiant
