Along the underground water network, the Lin Group's industrial park was separated, and by the time the members in charge of the broken were back on the ground, the surface of Iron Blood City was empty. At this moment, the invasion of the planetary system has been decided. In the face of the enemy's absolute superiority, the defending fleet gave up holding on after only a little resistance, and ran away with the warships withdrawing from the range of the planetary system. At this point, the cave planet system has fallen, and only the passive resistance of the ground armed forces of a few planets such as the cave star remains. On the other hand, the main fleet, which was led out in advance, was blocked on the interstellar route at this time, and it was impossible to return in time for reinforcement in a short time.

Speaking of interstellar routes, we have to talk about the shipping lanes between planetary systems. Although there seem to be roads everywhere between the planetary systems, no matter how you sail, you can reach your designated destination. But in reality, there are not many channels between seemingly empty planetary systems that can actually navigate all the way. In other words, there are not many passages that have really been determined to be navigable. Star vehicles such as starships and starships will travel quickly between planetary systems by navigating with curvature. One of the prerequisites for curvature navigation is that there are no obstacles between each other, and it must be in a state of near vacuum. The principle of curvature navigation is to stir up the space of the three-dimensional universe to form a distorted high-dimensional space. The temporarily distorted high-dimensional space will be like stirred seawater, and under the reaction force provided by the surrounding seawater, it wants to return to its original three-dimensional state. In this way, the distorted high-dimensional space will give the battleship and spacecraft a reaction force, pushing the battleship to sail in the opposite direction.

High-dimensional space is like rolling a piece of paper into a paper roll, which greatly shortens the distance between two points that are originally far apart. If a certain size of meteorite fragments appear along the way of the warped space, the battleship and the spaceship will crash headlong at super high relative speeds, crashing into pieces! Even if the battleship and the spacecraft have special radar warnings, they need to sail out of curvature for a long distance before impact. In addition, the energy required to enter the curvature navigation state is much greater than the energy required to maintain the curvature navigation, and frequent entry into the curvature navigation state will cause a huge load on the engine block of the battleship and spaceship, and seriously affect the service life of the engine!

Therefore, the perennial maintenance of the main and secondary routes of the interstellar route has become a necessary channel for smooth navigation between planetary systems. The interstellar caravans with the goal of making profits naturally choose these guaranteed routes.

On the other hand, the tactics adopted by the interstellar pirates are to frequently drop meteorite fragments on the retreat of the main fleet of the cave planetary system. In this way, the interstellar pirates severely slowed down the main fleet of the planetary system, making it impossible for them to return in time, buying the interstellar pirates to wreak havoc on the Cave Star for several days.

Judging from the current situation, even if the main fleet of the cave planetary system returns to the cave planetary system, it will encounter an attack by interstellar pirates. In the case that there is no huge difference in combat effectiveness between each other, the interstellar pirates can use the planets and stars in the planetary system as "shields" and bunkers to fight against the return fleet that has no cover to hide their bodies on the periphery of the planetary system in the form of positional warfare.

All in all, the situation on Cave Star will not change anytime soon, and the interstellar pirates will take over the planetary system in the next week to a month.

Iron-Blooded City is located southeast of the outskirts of the city, in a "safe zone" that serves as a bridgehead into Iron-Blooded City. Soon, the interstellar pirates that cut into the planet's atmosphere from the southeast of Iron Blood City will arrive in a close-to-ground flight and lead the vanguard to the city's various anti-aircraft fortresses to disarm the city's anti-aircraft fire network. After the city's anti-aircraft fire network is lifted, there will really be no hostile armed forces in the city who dare to appear on the ground.

Now, Zuo Zhe appears as a smiley ghost in an underground stronghold in the security zone, and the members of the Gray Raven Group who have failed their mission wait for instructions on their next step.

For the Crows, the most likely possibility that the mission has failed is that the enemy has cracked the keys to their side. Combined with the previous incident of blood wolf and other special forces arresting the target and being killed, the threat of the target Zuo Zhe has been greatly increased. However, for the members of the Gray Raven Organization who have just experienced a strange battle, the most important thing at the moment is not to find the mission target to hide, but to kill the vulnerabilities and patches of the intelligent terminals in the individual mecha, and add new firewalls, and update some core key and password programs.

By the way, the mobilized network experts can also find out the real reason for the intrusion of their own network through the historical records in the individual mecha intelligent terminals. In the end, it was because of the leakage of the intelligent terminals of the special forces such as the blood wolf, but because the reinforcements on the target person's side invaded their own network system.

This is very important, and very urgent. Even if you can't gain the upper hand in intelligence warfare, you can't fall behind from the beginning. If the enemy always knows in advance what their next plan of action will be, it will be difficult to carry out the next search plan. In addition, self-examination can determine if there are undesirable enemies hiding in your team. As the party that invaded Iron Blood City, if you don't do a good job of guarding against it, it will be a shame if you are invaded by the enemy in the opposite direction.

In the cab of the individual mecha, through the powerful network intrusion ability of the Terminator, Zuo Zhe learned the thoughts of a group of middle and high-level members led by Commander Sen Luo. If Zuo Zhe didn't do something, he would be asked to come out of the cab of the individual mecha for inspection. Although he has multiple passwords such as DNA, pupils, and fingerprints of the smiling ghost, the liquid terminator can also disguise Zuo Zhe's appearance to be highly consistent with the smiling ghost, but Zuo Zhe does not think that he can hide it from the investigation of those who have a heart.

Therefore, Zuo Zhe revealed the secrets of the security zone and the pirate's attack plan to the garrison of Iron Blood City through the Terminator in a way that the other party could not discover. If you can eliminate the "safe zone" on the invader's side in Iron Blood City in advance, the enemy's subsequent invasion will lose the bridgehead, and the pace of attacking Iron Blood City will be slowed down. If the pirates' attack goes too well, it will seriously undermine the confidence of the defender. If the gap between the defending side and the attacking side is too large, the defending side is likely to be coerced into arresting Zuo Zhe. At that time, Zuo Zhe will really become a sandwich cake and fall into the situation of being attacked on his belly and back. And if Zuo Zhe's next plan is to be implemented, there needs to be a prerequisite, that is, the situation in the Earth Cave Star must remain in a state of stalemate and turmoil, and there can be no one-sided situation!
