Phantom Beneath the Sea

"Beep... beep... beep... beep..."

When the Level Two alarm sounded throughout the base, Pioneer immediately contacted the command center's central AI.

"Central AI, report the situation!"

"Commander, the underwater early-warning radar deployed in the coastal waters has detected some unusual fluctuations. They are suspected to be Decepticons!"

The underwater radar had originally been deployed around Trindade Island to scout the increasingly frequent activity of submarines from various countries in the surrounding waters.

Later, following the invasion of the Replica Soldiers, Sun Cheng and the others discovered during their postwar review that the island's security and defense systems had far too many flaws.

As a result, the island's defense systems underwent a comprehensive upgrade.

The underwater detection radar originally deployed in the surrounding waters to monitor submarines from various human nations was also included in the upgrade.

After several months of technological improvements, radar had now been deployed not only around Trindade Island, but around several other islands as well.

The new underwater radar could detect not only submarines operating in the surrounding waters, but also the various unmanned deep-sea exploration devices that had risen to prominence in recent years.

It could even detect Decepticons and Autobots.

However, due to a number of limitations, although the underwater radar had a detection range of 470 kilometers, it could only confirm whether a target was a Decepticon or an Autobot after it entered the radar's optimal detection zone—within 130 kilometers.

The moment Pioneer heard the central AI's assessment, a fierce look appeared on his face.

"Send me the coordinates and more detailed information. Keep monitoring them closely and provide me with real-time data updates!"

"Yes, Commander!"

Pioneer largely agreed with the central AI's assessment that the suspicious intruders were likely Decepticons.

They still maintained some cooperation with the Autobots. Although Sentinel Prime's existence
