Pirates are a very distant existence to Zuo Zhe. Before the crossing, the places where piracy occurred on Earth were generally in the Strait of Malacca and the Gulf of Aden. In Zuo Zhe's inherent understanding, pirates would only operate in those very backward places. But now, Zuo Zhe's preconceived notions have been seriously impacted. In other words, it was Zuo Zhe who recognized the essence of the Earth Cave Star. On Earth, these remote places are as remote and chaotic as Somalia, and interstellar pirates are rampant.

Before Ruiya came to the Earth Cave Star, he had a general understanding of the security around him. It stands to reason that in recent years, interstellar pirates have not been as rampant as in previous years. The biggest characteristic of pirates is that they are afraid of the hard, even if they have the combat power to forcibly gnaw the hard bones, they will not go to the enemy with strong defense forces because of serious logistical problems. As for the direct invasion of the cave planetary system like the current one, it is even rarer.

Regular interstellar pirates certainly don't gnaw hard bones, but what about those unconventional pirates? For example, the private armies who have been secretly cultivated to act as hole cards. Interstellar pirates are a trump card used by big conglomerates to attack their rivals. If you can't openly go to war with your competitors on the surface, you can send out secretly stored private forces at the critical moment of legitimate competition, disguise them as interstellar pirates, and launch a fatal blow against the rivals' important fleets.

This kind of trick is not uncommon for the big forces, in fact, some of the interstellar pirates around the Earth Cave Galaxy are secretly supported by the major forces. But the problem is that there is no one force in the Cave Star that can gather a pirate force that is enough to launch a planetary system invasion war! After this battle, the consumption of interstellar pirates will undoubtedly be very huge. Moreover, as soon as the garrisons of the surrounding planetary systems react, they will come to support the battle. At that time, the interstellar pirates with weak logistics can only retreat after grabbing a wave. And once the power of the interstellar pirates is exposed, those greatly affected consortia will hire a powerful bandit fleet from other planetary systems for their own safety.

Unless something particularly serious happens, interstellar pirates will not rush into a large-scale invasion.

Now, the invasion of the interstellar pirates has proven the importance of Zuo Zhe. While there is no direct evidence, there are many things that do not require evidence. Now, the high-level leaders of the Earth Cave Star have two choices, the first is to hand over Zuo Zhe for the peace of the Earth Cave Star. As for whether the interstellar pirates will stop there, it depends on whether the follow-up military compensation is powerful. However, even if you want to compromise with pirates, you can only compromise in private. If it is put on the table, the face of the ruler of the Cave Star will be lost.

The second option is that the more the enemy wants to get it, the more they can't get it. And no matter how the high-level of the Cave Star chooses, Zuo Zhe will face the attack of the high-level of the Cave Star and the interstellar pirates next! Now that Zuo Zhe's importance has been further strengthened, it is entirely possible that the elite troops that would not have been used to arrest Zuo Zhe will be able to play!

The news of the interstellar pirate invasion of the cave planetary system does not seem to be directly related to Zuo Zhe, but this news has a great warning significance for Zuo Zhe. After learning that the interstellar pirates had taken advantage of the situation to launch an invasion, the threat to Zuo Zhe suddenly increased a lot! Fortunately, the interstellar pirates are invading the Cave Star, which has caused most of the attention of the Cave Star garrison to be attracted to the interstellar pirates, and they can only send a small group of elite troops to capture Zuo Zhe.

Therefore, what Zuo Zhe really wants to say is to retreat quickly!

How to retreat? Do you want to use the Python form war mech that you just loaded to dig a hole in the ground and retreat? Retreating underground is not a good option, and even very advanced tunneling rigs can inevitably cause huge vibrations during the tunneling. The speed of underground retreat was relatively slow, and it was difficult to leave the Iron Blood City, which had a diameter of thousands of kilometers, in a short period of time.

With the Terminator, a super individual vehicle that surpasses the current era, Zuo Zhe has a new idea in his heart. And once this idea popped up, it firmly occupied Zuo Zhe's thinking, and it was difficult to get rid of it.

Iron Blood City is now in a state of combat readiness, and the high-energy particle cannons in the underground fortresses throughout the city have quietly revealed their hideous cannon muzzles. Protected by the Massive Energy Shield Generator, these muzzles unleash deadly artillery strikes on enemies who dare to appear in the Cavestar's outer vision.

However, this anti-aircraft weapon actually did not play much of a role. In general, in a landing operation in the atmosphere of the planet, the commander of the landing force will not attack from the sky above the city as long as he still has brains. The attacker's fleet will cut through the wild part of the planet's atmosphere from a cloudy position on the dark side of the planet. After cutting into the planet's atmosphere, the first landing force will quickly switch to an ultra-low-altitude ground flight mode, using the cover of the spherical surface to quickly approach the target city by flying close to the ground. At that time, with the ploughing firepower of the interstellar warships in outer space, the landing force will be able to quickly attack the target city, disarm the anti-aircraft fire in the target city, and let the enemy in the target city only dare to survive in the passage below the surface under the deterrence of outer space firepower, like a rat in the sewer.

As the first priority target city for interstellar pirates, Iron-Blooded City is surrounded by large expanses of dark red open-pit hematite mines. In these inaccessible open-pit iron mines, the enemy can choose any direction to launch a landing operation. This is very bad for the defending side.

However, today's interstellar pirates have not yet invaded the planetary system where the cave star is located, and they are still in the battle stage for outer space. By "planetary systems" we mean planetary systems that have only one central star within them. Planetary systems with two stars orbiting each other or even more stars in a planetary system will be specified. In fact, almost all ecological planets are located in single-star planetary systems. By contrast, planetary systems with two or more stars are mostly violent in terms of external conditions. And if there are three stars in a planetary system, then there are basically no planets in that planet system. Attracted by the gravitational pull of three stars at the same time, there are not many planets that can withstand such a harsh and changeable external environment without collapsing. Even if there are one or two planets, it is almost impossible to be ecological planets suitable for life.

With the current emptiness of the Cave Star System, it is almost impossible to resist the invasion of interstellar pirates. It won't be long before the main fleet is lured away in advance by the pirates and the Cave Star will be successfully invaded by pirates and a landing operation will be launched. There is not much time left for Zuo Zhe, and Zuo Zhe must seize the world to carry out that seemingly crazy, but in fact very feasible plan.
