According to what Shen Bing had learned through Qiuqiu, the pirates led by the bearded Sang Ze were indeed local pirates from the waters around Malacca. The speedboats and submarine, however, were rather mysterious.
Speedboats were difficult to track, but submarines were easier, especially for Qiuqiu, who controlled every satellite in the world and could use navigation data to trace the course of any vessel.
Yet there was something strange about this situation. The submarine seemed to have appeared in those waters out of nowhere, with no trace of its movements before or afterward.
There was only one possible explanation: the submarine had switched off its radio transmissions and maintained radio silence both on its approach and while fleeing the scene.
For a submarine, radio silence left its crew effectively blind. Still, with someone possessing exceptionally extensive seafaring experience at the helm, it could navigate safely.
Although Phantom Immortal Technology possessed powerful technology, it could do nothing about a submarine traveling underwater without transmitting radio or navigation signals.
That made it difficult to identify the people behind this through that lead. All that remained was to rely on Mr. Old Charlie.
This was indeed a more promising avenue. After compiling information from around the world and running big data analyses and comparisons, Qiuqiu had uncovered a few clues.

This organization was strictly an intermediary, and an extremely mysterious one. It never dealt directly with clients. Both the backers who issued jobs and the mercenaries who accepted and completed them conducted their business through individual covert agents.
Such an arrangement was understandable. Many mercenaries undertaking these jobs were high-risk individuals. If the two sides made direct contact, any exposure of their identities could
