It is said that several days before Xiang Shan and his group's arrival, a fleet of engineering ships had departed from the Republic's Qiongya Port and arrived in Indonesia the day before to begin their operations. They were filling sand and soil along the edge of a bay, working together with the Federation's construction team to construct a dike right along the edge of the strait.
At the same time, the Federation was also erecting several partitions within the bay using massive steel plates to block the flow of sea water and simultaneously using pumps to extract the water inside.
Considering the pollution issue, this seawater was not discharged directly into the sea but was temporarily contained in all available vessels.
This was said to be the achievement of the Peacekeeping Forces.
