Sun Guang was continually strengthening the Dorne defense line he led, and over the past few days, he gradually received many...submarines from Qin Country.
A year ago, Qin Country began a large-scale construction of submarines to make up for the lack of a navy and insufficient combat strength, but the results were unsatisfactory.
Most of Qin Country's submarines and submarine supply ships were ineffective. Even after the loss of Shu Territory, they were chased all over by the Great Tang Empire's destroyers and anti-submarine helicopters.
With the loss of Shu Territory, the remaining submarines lost their supply base, forced into exile, with those having sufficient fuel ordered to regroup at Dorne.
Of course, most submarines were directly captured by the Great Tang Empire due to lack of fuel, leaving them no choice but to surrender obediently.
