The power of the three ships that can deter a small country even if they are pulled out in peacetime is not inferior at this moment, and there is nothing else on the Nuoda River except this lone fleet, and the Jinling section of the river, which used to be extremely busy, now looks like a dead field, and it is no longer as prosperous as it used to be. www.biquge.info The military region, which was seriously short of steel, even used its main battle tanks to drag the huge ships that drove into the moat ashore, artificially stranded in front of Jinling City, the entire deck was cut and re-welded on the newly built reinforced concrete wall, all electronic instruments and cables were completely removed and transported into the city, and some T-shaped parts that looked really piercing were installed on the steel wire mesh outside the city.

Not a single part of the freighter was wasted, so much so that after the construction of the Great Wall, only deep ravines left by the sharp bottoms of the ships that were dragged down were left on the plains, and the originally dense ships had long since been transformed into the pillars that supported the defense of Jinling.

There is only this fleet on the empty river, but it does not mean that there is nothing else under the turbulent undercurrent. Four mini-submarines with long guns, not much bigger than a car, were cruising around the fleet, and if you excluded their metallic sheen, they were almost as bloated sharks, and no one could tell the difference between them and live fish at a glance under the refraction of the light underwater.

Out of vigilance against the possibility that the swarm might successfully mutate into an underwater force, Qin Feng emphasized to Wang Ba at the beginning of the establishment of the navy that it must have sufficient anti-ship capabilities before having a fleet, and the flexible underwater unit is a weapon to ensure that it is invincible in the face of the swarm and the human fleet.

Before the fleet officially embarked on the voyage, there were already two spear mini submarines secretly out of the hidden shipbuilding base from the water and swam along the channel of the current fleet, Qin Feng naturally would not let the ocean-going giant ship worth 10,000 gold just casually embark on an unknown route, the hydrological data of this section of the Yangtze River has been collected, and the thick red long line on the screen in the bridge is the data display of the Yangtze River.

Under the premise that he could not obtain the landform of the motherland with military-level accuracy, Qin Feng chose to measure this eternal land inch by inch, and the existence of the blasting robot brought a lot of convenience to this plan, but it was helpless against the waters, and the timely appearance of the spear mini submarine undoubtedly filled the lack of small reconnaissance and offensive weapons in the waters.

The map shows that the fleet had just passed through the Yuqiao Town Farm, and the Yangtze River at the corner of the corner restricted the view from the towering bridge, otherwise they would have been able to see the battle position that Qin Feng had predetermined for them, the Second Yangtze River Bridge. However, considering the range of sight at night, none of the people on the bridge chose to look at the scene outside the inclined porthole, and the captain who had been reminded by Wang Ba was standing on a high position in the middle of the bridge to receive data feedback from the razor cruisers and spear mini-submarines around him to judge the safety level around the battleship.

All the military region can do is to send frogman troops to land the ownerless ships that are still floating on the river, drive them along the dug moat into the outside of the city, and then artificially run them aground, but when the insect swarm has just invaded the earth, many insects smashed on the ships transporting sand, gravel and coal that are still sailing on the river, and some of the ships whose crews were slaughtered collided together and finally sank after losing control, and these shipwrecks are even more threatening after months of erosion of the river and the capsizing of the sediment at the bottom of the river. The steel parts that burst out due to the pressure at the bottom of the river could collide with the fleet sailing at full speed on the river at any time, and what was even more deadly was that the fuel tank of the sunken ship was blocked by the sand and mud at the bottom of the river at the beginning of the sinking, so that the diesel fuel that became extremely viscous under the pressure of the water did not begin to leak from time to time until nearly half a year later. If it's just the problem of oil leakage, it's nothing, as long as the fleet finds it in advance, but the problem is that the fuel leakage is still ongoing, when the lance mini submarine first detected the Yangtze River waterway, a submarine inadvertently drifted to the top of the sunken ship in the process of avoiding floating metal objects, and suddenly a black current gushing out from the bottom of the river completely wrapped the small submarine from the bottom to the top. With the help of the backwash of the current, most of the oil was left behind, and now there were three submarines accompanying the fleet, and the sparks from the collision of metal parts and the hull of the submarine were enough to turn a submarine covered in diesel into an oversized grilled fish.

Before this, no one in the peacekeeping force considered that there would be a spark under the water, but after this incident, Qin Feng's cognition was refreshed again, under the viscous diesel oil that produced mutations under high pressure, only a slight impact between iron and iron was needed, and the environment isolated from the river water was enough to ignite the weakest sparks, which may not be observed by the naked eye, but the temperature that reached the ignition point was real, and the ignition point of diesel fuel was only 220 °C under general atmospheric pressure, Not to mention other bizarre conditions that can arise under the pressure of the river bottom, such as the fact that it only takes 110°C for these substances to ignite.

After all, the Lance Mini Submarine is designed for underwater navigation, and one of its particularly advanced configurations is a sturdy anti-condensation hatch, but at the beginning of the design, the Navy's engineers did not take into account the existence of high temperatures underwater, and they were more worried about the problem of freezing the shell of the submarine in the polar regions. Avoid it.

The shell of the submarine will undoubtedly become as brittle as a biscuit under the dual action of the scorching flame and the low temperature of the water, and although the general-class battleships and razor cruisers are made of impact-resistant nanosteel hulls, the seemingly sturdy bottom will be in a state of helplessness when encountering high temperatures, and nothing can be all-powerful on land, sea and air under the current level of technology, these warships are not super fortresses equipped with multi-directional sea/air thrusters, and they must always be on the lookout for those small but deadly threats in the changing water.
