Although Yang Yi and the others actively asked for battle, Karl did not immediately arrange tasks for them, but called up all the information related to the battle and asked them to figure out the battlefield situation first.

After reading it patiently, Yang Yi and the others knew it in their hearts.

Three days ago, the fleet of the Silicon Alliance suddenly appeared, blocking Prometheus with a thunderous force before the garrison could take action, and also shot down several reconnaissance ships sent by the garrison. Immediately after sending out the signal for help, Colonel Carr made a military deployment according to the plan.

In the defense deployment of Prometheus, the garrison base known as "North Star" and the mercenary base called "South Pole Star" are two support points, which have irreplaceable value. To put it simply, these two bases are indispensable, and the fall of either base will make the garrison's defensive deployment an ornament.

Here, a secret of the First War Zone is involved.

Thousands of years ago, after the capture of Prometheus, the First War Zone made an extremely ambitious construction plan to build Prometheus into a frontier fortress. It's a pity that the subsequent armistice agreement made this dream come to naught, but Marshal Sean, the commander of the First Theater of Operations, did not give up Prometheus Star. Everything that has happened since then has to do with it, but it's not that simple.

According to Sean's vision, the first war zone will completely rebuild Prometheus and completely rebuild it according to the standards of a space fortress. The most important thing is to install an SSS-class Origin Energy Converter in the center of Prometheus Star, making it an energy source for the entire military fortress. If this plan is successfully completed, then Prometheus will be built into a space fortress hundreds of years ago.

Although Sean's grand vision did not become a reality due to the armistice, the military bases in the north and south poles were planned before the operation to transform Prometheus was halted. And construction began. These two military bases are of vital value in the defense of Prometheus. That is, through these two military bases, the energy provided by the Origin Energy Converter will create a strong geomagnetic field for Prometheus, which will protect Prometheus through the geomagnetic field and change the environment of Prometheus Star. If war breaks out. It can also transform the geomagnetic field into an energy barrier by enhancing energy.

It can be seen that if Sean's plan becomes a reality, Prometheus Star will become a super space fortress like "Kuhn-Barion".

Although it did not become a reality, the construction of the two military bases was completed one after another.

Hundreds of years later, the S-Class Origin Converter removed from a scrapped warship in the First Theater was sent to Prometheus and installed in two military bases. In addition, after several generations of efforts, the geocentric tunnel connecting the two military bases has also been completed.

Although there is a big difference from Marshal Sean's vision. But Prometheus' defense deployment is already beginning to take shape.

That is, with the use of two S-class Origin Energy Converters, a slightly weaker geomagnetic field can be created to provide the most basic defense for ground bases.

However, in the past hundreds of years, these two primordial converters have never been running at full power, and the equipment used to create the geomagnetic field has never been used.

In Carr's words, it is questionable whether the equipment that creates the geomagnetic field will be able to function properly. But it was necessary to open a tunnel in the center of the earth to connect the two military bases. to start the equipment. Only by activating this set of equipment can you block enemies from outer space.

Karl thought of this when the enemy attacked.

Unfortunately, the liaison officer he sent to the "South Pole" base never returned, and the tunnel train used to transport personnel and supplies was destroyed shortly after the enemy landed on Prometheus. Three days. Karl didn't know anything about the situation at the Antarctica base.

In order to prevent the enemy from attacking from underground, Karl had already ordered the tunnel to be blocked.

Obviously, this is not a long-term solution.

"The attack came so suddenly, and although we took immediate action, it was less than four hours later. The enemy landed on Prometheus and surrounded the base. None of the scouts I sent out came back alive, and even if they were, they would be unlucky. Karl sighed and said, "It's not clear what the enemy is doing, but the destruction of the tunnel train in the center of the earth must have been the work of the enemy. So far, the enemy has launched more than 20 attacks, and although a large number of troops have been invested each time, they have never sent out troops to attack the fortifications, otherwise we would not have been able to hold out for so long. In my guess, the enemy must have focused on the south. ”

"Concentrate forces on the Antarctic base?"

Karl nodded and said, "Anyway, we are a regular army, and we have plenty of ammunition and supplies, and we all have strict military training, so we can hold out even if we are besieged. Guarding the base of the South Pole Star are interstellar mercenaries, although some of them are retired soldiers, and their quality is no worse than ours, but most of them are outlaws, even if they have strong individual combat effectiveness, they cannot fight collectively like regular troops. ”

"There is no doubt that the difficulty of attacking the South Pole Star base is much lower."

"If I were the commander of the Silicon Legion, I would attack the Antarctic base first."

Karl shook his head with a wry smile and said, "If the South Pole Star Base falls, we can't hold it here, the enemy will open the tunnel in the center of the earth sooner or later, and it won't take much time." What's more, as long as the enemy enters the center of the earth, they can control the entire Prometheus star. ”

"Control?"

Karl gritted his teeth and said, "Transform Prometheus Star into something that is not suitable for us to live in, or even survive here." ”

"What do you mean?"

Karl looked a little embarrassed and hesitated for a while before he said, "Although the plan to transform Prometheus Star was nullified by the armistice, the transformation work has been carried out secretly for the past hundreds of years, but the progress is slow. After all, this is a focal point for both sides, and any large-scale engineering work will raise suspicions. So far, the main infrastructure of the renovation project has been completed, and all that is missing is an SSS-class primordial energy converter and equipment to create geomagnetic fields. If our every move is under the watchful eye of the Silicon Alliance, then the enemy will be able to modify Prometheus in the same way, and even change the strength of gravity on the ground. ”

Yang Yi was slightly stunned, and the others also widened their eyes in surprise.

"There is no technical difficulty in changing the strength of gravity by distorting space. Silicon-based life is able to adapt to a stronger gravity environment, and if the surface gravity strength of Prometheus is increased tenfold, ordinary soldiers will not be able to survive here, let alone fight, even if they wear gravity-defying combat suits. If it is strengthened a hundred times, let alone me, an eighth-level soldier, I am afraid that even you will not be able to gain a foothold here. ”

Yang Yi sighed secretly, Carl was right, there was indeed such a possibility.

"It's a pity that we're too busy to take care of ourselves now, and we can't take care of other places at all. Besides, the base is already completely surrounded by the enemy, not to mention scouts, even unmanned reconnaissance aircraft can't fly out. Carl sighed. Before you arrived, I was almost in despair. ”

"What do you want us to do?" Lin Feng asked directly.

Karl gritted his teeth and said, "The top priority is to find out the situation at the South Pole Star base. If the Antarctic Star base has fallen, then there is no point in us staying here, we have to find a way to break through. If the base of Antarctica hasn't fallen, we'll have to keep fighting. ”

Lin Feng nodded slightly, indicating that he understood what Carl meant.

"In addition, we have to prevent the enemy from entering the center of the earth from somewhere else."

"How can I prevent it?"

"While it is easiest to capture the Antarctic Star base and use the Geocentric Tunnel, the enemy must have prepared for the worst-case scenario. With enough time, a dragon can make a way to the center of the earth, and the enemy may have already done so. ”

Lin Feng's brows jumped a few times, and his expression became gloomy.

"We can use the Shadow." Shen Chengwen saw Lin Feng's thoughts and said, "In addition, scouts can also be dispatched." ”

"Scout?"

Shen Chengwen nodded and said, "Ordinary soldiers can't pass through the enemy's encirclement, but soldiers can, and our people can act alone, at most two people in a group." There are fewer people, small targets, and it is more difficult to be detected by the enemy. It's just that we have to find the right direction. Simply put, which place is the best place for the enemy to make holes. Prometheus is so big, you can't just look around aimlessly. ”

"Actually, this is also a problem of the enemy." Yang Yi said.

Shen Cheng was slightly stunned when he heard this, and cast an inquiring glance at Yang Yi.

"Prometheus is a planetary celestial body, too big for us to hold all the places. Obviously, it is also impossible for the enemy to occupy everything. Although the base is surrounded by the enemy, the enemy commander will not be confident enough to think that he can trap us completely. In other words, if Colonel Carr's speculation was correct, and the enemy was trying to make a hole, he would certainly have sent heavy guards. From the point of view of saving troops, the enemy will choose to be near the place where the troops are assembled, that is, somewhere near the South Pole or the North Pole. Yang Yi paused slightly, and then said, "Obviously, in order to save time, the enemy will choose a valley with low terrain. ”

Shen Chengwen nodded thoughtfully and looked at Karl.

"Here." Carl gestured to the three-dimensional map. "This Grand Canyon is about five hundred kilometers away from the base, and the deepest part of the canyon is about five thousand meters, which is the deepest canyon within a radius of a thousand kilometers, and it is large enough to accommodate a large army, not to mention a few earth dragons."

"So, we already know where to go to scout the enemy."

"It's better to be careful." Lin Feng glanced at Yang Yi and said, "Let the 'Shadow' pass first, and after discovering the enemy, it's not too late for us to go over." ”

Lin Feng said so, Yang Yi was not easy to object, and others were even more so. (To be continued......)
