On the west coast of the White Eagle Federation, 160 kilometers offshore, there is an island called Prudence Island. This island is not well-known because it is a private island, not open to the public, and it has no ports, making it inconvenient for large ships to dock. At this moment, three teams are conducting reconnaissance of all sea, land, and air positions around the island, expanding the reconnaissance range to fifty kilometers. To be on the safe side, they also conducted reconnaissance of the underwater environment, deploying the Deep Sea Team. Liu Haiyang and Jiang Shaoran led the Deep Sea Team, staying underwater a day ahead, and even figured out how many types of coral polyps grew in the surrounding reefs. After the Abyss Battlefield in the Sea Demon World, the Deep Sea Team led by Liu Haiyang became the most powerful force beneath the sea in the Human World, unmatched by any other. Moreover, human technology struggles to be effective underwater. Although humans can build submarines, even nuclear submarines, due to the low visibility underwater and the presence of ambient ocean noise, submarines in the sea are like blind men, relying only on sonar to hear. When two submarines encounter each other underwater, their contest is like two blind men listening to each other’s movements, too afraid to start their engines, silently lying at the seabed listening.

The advent of the Abyss Era completely changed the rules of underwater games. Powerful ocean system superpower users had fully mastered sea supremacy. Since superpower users are too small, they can only sink to the seabed, and even if the sky is full of anti-submarine aircraft, it is impossible to find ocean system superpower users. However, ocean system superpower users can easily locate submarines as long as they enter the search range. Especially Jiang Shaoran, with the class of a Spiritual system Wave Summoner, can produce a subtle response with seawater, and all movements at the seabed cannot escape her perception. Therefore, human technological methods are completely powerless against ocean system superpower users. To vie for sea supremacy can only be a contest among ocean system superpower users. At present, Da Xia has the strongest deep sea team on Blue Star, unmatched by anyone else. As soon as Liu Haiyang’s Deep Sea Team enters the sea, they become the overlords of this ocean. Of course, Liu Haiyang often jokes that when the six of them come ashore, they are just six salted fish. While not as weak as ordinary people, their combat power is indeed halved. This is the price to pay for ocean specialization, but it is a valuable price. For most superpower users, being the best in one field is the best choice. Even Lu Heng wouldn’t compete with Liu Haiyang and his team in the sea. The three teams were responsible for protecting Yu Zhenhai, Shen Yunyue, and three others, conducting reconnaissance in the waters around Prudence Island to ensure that there were no ambushes on all islands and reefs within fifty kilometers. Finally, they reconnoitered the island itself. The whole process went smoothly, without finding any traps. Even the researchers on Prudence Island were working as usual, and the ships transporting food and materials docked as usual. After the reconnaissance was complete and confirmed no issues. When night fell, Lu Heng officially landed on Prudence Island, penetrated walls to enter the laboratory, and then searched for the Life Tree Vine in the lab. During the process, he encountered a researcher, whom Lu Heng controlled using Spiritual Dominance and inquired about the machine room where experimental data was stored. He copied a set of experimental data to take away, and then found out the location of the Life Tree Vine storage. The Life Tree Vine was stored in an encrypted storage room with a triple-password alloy door. Lu Heng didn’t need these, he directly penetrated the wall and saw the Life Tree Vine in a cylindrical glass case. The emerald energy-based vine quietly floated inside the glass case. Lu Heng chopped open the glass case with a sword and took the Life Tree Vine in hand. As the glass case was shattered, the alarm in the laboratory went off, alerting all the duty personnel in the whole lab. After obtaining the Life Tree Vine, Lu Heng performed a Void Flash to leave the lab and joined the team members to depart Prudence Island. The whole process was unexpectedly smooth. In fact, Lu Heng even began to suspect that the Life Tree Vine he had obtained was fake. So on the way, he handed the Life Tree Vine to Su Muyu to check its authenticity. After inspection, Su Muyu confirmed that the Life Tree Vine was real: "Finally retrieved the Life Tree Vine. Now I can go to the Elf World to help Queen Orelana remove the necromantic aura." Before dawn, all operation personnel returned to the Dragon Power Base. After roll call by the team leaders, it was confirmed that there were no people missing. This operation was highly successful, even to the point of making one feel uneasy. If it weren’t for knowing that the last operation almost fell into an ambush, this one might have been considered making much ado about nothing. Obviously requiring only Lu Heng to enter the lab and retrieve the item, yet reconnaissance of the surrounding waters was conducted two days in advance. Of course, any soldier with military experience wouldn’t consider detailed reconnaissance as making much ado about nothing. Only saturation reconnaissance can ensure operational success and personnel safety. Besides the Life Tree Vine, Lu Heng also retrieved a complete set of experimental data from the Prudence Island laboratory. After returning, he handed it over, and a dedicated research team will study the experimental data. The next day, Lu Heng received a preliminary analysis result of the experimental data from Qi Jinhui.
