Lin Xuan drove the car and returned to Las Vegas smoothly, and after resting there for a day, he returned to Huaxia again, and then went directly to Hook Fishing Island.

There are Huaxia warships patrolling around Hookyu Island, so Lin Xuan doesn't have to worry about spies from other countries approaching the island, and the first thing to build on the island is the monitoring system and basic defense system, and all of them are handed over to Jarvis to manage, monitoring the island all day long, as well as the movements on the surrounding hundreds of meters of sea.

Once an unknown person is found to be approaching, the basic defense system will definitely not allow the other party to land on the island smoothly, and Jarvis will also send an alarm reminder to Lin Xuan.

But fortunately, during Lin Xuan's absence, no one else approached the island.

Now that the construction of the defense system of Goyu Island has been completed, it is expected that it will be completed in another ten days, and this island will become an island of science and technology with the world's most advanced defense weapons and the most reliable defense system.

The factories here will also produce some of the most advanced technology in the world, and the core of the future world may be the island.

Thinking of this, Lin Xuan seemed to suddenly understand the reason why the system allowed him to build an island of science and technology.

Do you want me to take this as the core and foundation to realize the great cause of changing the world's science and technology?

But what is the purpose of stealing the red spar this time, and what is the connection with this island of technology?

Lin Xuan couldn't figure it out, and in the next ten days, Lin Xuan also carefully studied the black cylinder, but no matter how he studied it, he couldn't figure out what it was and what it did.

He even asked about the system. However, the system only reminded the red spar that it could not be separated, but did not give any explanation for the red spar.

……

this day. The island's defense system was finally completed, and Lin Xuan and Jarvis inspected the island's entire defense system.

"Sir. The defense system has been checked, and everything is fine! ”

"Okay, Jarvis, now through our satellite base station, try to connect to the American military satellite!" Lin Xuan said in a deep voice.

"Okay, sir, the connection is expected to be completed in ten minutes!" Jarvis replied, and a connection progress bar appeared on the computer screen.

Lin Xuan knew very well that although the defense system and defensive weapons on his island were the most advanced in the world. But that's not enough to make the island the safest in the world.

Moreover, many missile interception weapons on the island need the cooperation of early warning satellites, radars, and other facilities, and although Lin Xuan has built radars on the island, he does not have early warning satellites.

Therefore, he can only borrow the early warning satellites of the United States, and not only that, Lin Xuan also plans to directly borrow the missile defense system established by the United States around the world.

You know, the United States currently has the most comprehensive ballistic missile defense system in the world, which can intercept all types of ballistic missiles.

This kind of system is mainly known to consist of five major components, namely, early warning satellites, improved early warning radars, ground-based radars, ground-based interceptor missiles, and combat management command and control communication systems.

Among them, early warning satellites are used to detect the launch of enemy missiles, provide early warning and information on the launch and landing points of enemy ballistic missiles. These satellites are space-based infrared systems. That is, missiles are detected by the infrared radiation signal of the smoke and fire ejected by the enemy when the missile is launched.

This is the top priority of the entire system, and it is also the reason why Lin Xuan wants to control all the American early warning satellites, because these satellites will also provide useful information for the defense system on his island.

And the improved early warning radar is equivalent to the "eyes" of the missile defense system. It can warn targets at a distance of 4000-4800 km.

The radar built by Lin Xuan on the island is even more powerful than that of the United States, capable of warning more than 9,000 kilometers.

Ground-based radar is an X-band, wide-band, large-aperture phased array radar that directs ground-based interceptor missiles into operational airspace.

Ground-based interceptor missiles consist of booster rockets and interceptors (warheads). The former sends the interceptor closer to the target, and the latter automatically adjusts the direction and altitude. Collide with the target after finding and locking onto it, knocking it out into space.

However, the interceptor missiles on Lin Xuan's technology island are more advanced. Its intelligence allows it to accurately find enemy missiles without the help of ground-based radar, and it can reach speeds of more than 40 times the speed of sound.

Finally, it is the combat management command and control communication system, which is also the system that Lin Xuan once controlled, and now Lin Xuan's Jarvis 2 is still hidden in this system.

This system belongs to the brain of the entire missile defense system, and it uses computers and communications networks to link the above-mentioned major systems to control 24 low-orbit early warning satellites and six high-orbit satellites that constantly rotate around the earth all day long.

As soon as an enemy missile is detected, its infrared radiation signal is tracked.

Through the combat management command and control communication system, the satellite not only "informs" the command center of the missile's flight trajectory, but also indicates targets for the early warning radar and ground-based radar.

After the early warning radar finds the target, it relays the tracking and evaluation data of the missile to the ground-based radar.

As soon as the launch order was received from the American Space Command, the interceptor missile took to the air. After the interceptor relied on the infrared detector it carried, it collided with it with all its might, and died with the other party.

Therefore, Lin Xuan wants to control not only the early warning satellites of the United States, but also the combat management command and control communication system of the United States.

Although this system belongs to the American military network, and the external network is generally impossible to invade, Lin Xuan asked Jarvis to directly invade the American military satellite through the satellite base station he established on the island, and this invasion process is actually not difficult, after all, those satellites have been controlled by him and have done some tricks.

Then, through military satellites, it got in touch with the Jarvis 2 hidden in the US military network, and then quietly controlled the entire combat management command and control communication system, as well as the US missile defense system.

Unless the United States deactivates all of its military satellites, it will never be possible for him to terminate Lin Xuan's control of their missile defense system.

Of course, Lin Xuan's control is not completely controlled, but it is a secret borrowing, which gives Jarvis a permission in the system, so that Jarvis can also control the system.

But it has not changed the control authority of the US military over the system, and Jarvis's control authority is also carried out in secret, only when he needs it, Jarvis will directly control the entire system, and usually just borrow their early warning satellites and some early warning radars to use the defense system on their island as eyes, and will never be found by the United States to find any clues.

"Sir has been successfully connected!" Jarvis's voice rang out again.

"Okay, immediately connect with Jarvis II and connect the American missile defense system with the defense system on our island!"

"Yes, sir—the connection has been made!"

"Well, that's good!" The corners of Lin Xuan's mouth hooked up a smug smile, with the United States' missile defense system as the first line of protection, and Huaxia's backing was his second line of protection.

And the island's defense system and weapons are the third line of protection.

In this way, his island is definitely the safest place in the world.
