W finally knew why this iron cube was so big, it was 400 meters long, 400 meters wide, and 40 meters high, because it was a large hydrogen reactor.

Only the hydrogen reactor can provide it with enough energy supply, so its size will be so large, and when the hydrogen reactor is turned on, it needs to reach a value of hydrogen activity before it can be turned on normally, so its previous ten minutes is not to wait, but to let the large hydrogen reactor enter the boot state.

W had heard about hydrogen reactors, and it was no secret that it was made public even before the catastrophe, and Starprint cooperated with power companies around the world to build many hydrogen nuclear power plants around the world.

The reaction source is raw hydrogen, which is a non-radioactive nuclear raw material, but the construction of hydrogen power station is a very complex matter, and there are many procedures in it, and there are many materials required, for example, the most important material is called rhodium crystal, but rhodium crystal is an extremely difficult substance to synthesize, that is a substance with a very high melting point.

When the Xingwen company was not mature for hydrogen technology, it relied on cooperation with power companies around the world to develop hydrogen technology, and the original hydrogen technology could not make hydrogen batteries, so the original exoskeleton armor was also purely electric, and the output and endurance were also pitifully weak.

However, since W knows that the core of the Flying Fortress is a large hydrogen reactor, then he also knows its weakness, the hydrogen reactor is a high-temperature fusion, the core temperature can reach up to 8,000 degrees Celsius, but the core fusion material is magnetically bound to the center of the reactor.

The rhodium crystal is fixed around the core, the melting point of the rhodium crystal is very high, and the excellent melting point can be used as the protective shell of the reactor, and secondly, it has a good thermoelectric conversion efficiency, which can directly convert hydrogen thermal energy into electrical energy under the impetus of the magnetic effect, so the power generation efficiency of the hydrogen reactor is very high, compared with the traditional boiling water nuclear power plant, the efficiency is hundreds of times higher.

So W also thought of its shortcomings, it is a heating monster, while generating a lot of electricity, it itself will also generate extremely high heat, so it also needs to be equipped with a large part of the space to make its supporting cooling system, if that's the case, then the Flying Fortress is a paper tiger.

W took off again, she flew to a very high position, and observed the sky fortress through the over-the-horizon function, the snow was very heavy, and it was all goose feather snow, but she found that there was no snow on the sky fortress, not even on it, but she looked carefully and found that there was a thin layer of fog on the sky fortress.

That is the manifestation of the snow flakes falling on it and being vaporized by the heat in an instant, that is to say, the surface temperature of the air fortress is also very high, which also proves that W's conjecture is correct, so how does it dissipate heat, W fell quickly from the sky, she began to fly at an ultra-low altitude to get close to the air fortress, and after a short sonic boom, she flew not far below the air fortress.

In fact, it is difficult to find the heat dissipation holes of the air fortress without looking carefully, its heat dissipation holes are almost on the ion thruster, W has always thought that it is the attitude auxiliary thruster on the ion thruster, W thinks that it is for the air fortress to control the attitude, because those heat dissipation holes emit a dark red light, and it is also these lights that interfere with W's judgment.

In fact, those red rays are just the hot gas formed by the heat dissipation of the air fortress, and the gas is mixed with the coolant used for heat absorption, and after absorbing enough heat, a faint red fire is formed at those heat dissipation holes.

Immediately, W immediately connected to Mia through the Starstripe Interactive System.

"Mia, are you on Jack's side, let John immediately order, transfer all the starstriped test subjects to support me, I have found a way to destroy the Flying Fortress." W shouted, she had found the weak point of the Flying Fortress, but the Aerial Fortress was already close to the Resistance's large forces, and its ultra-high-energy ion cannon was already accumulating, and it would not be long before it could be fired again.

Mia sits next to Jack in one of the evacuated Resistance armoured vehicles, but she then snatches the walkie-talkie from Jack's hand that is connected to John's side, and sets her helmet to the public so that John can hear W directly through the walkie-talkie.

"Sister W, you can say it, Uncle John, he can hear it now." Mia replied.

"John, you immediately order all the star-striped test subjects wearing exoskeleton armor to come to my aid quickly, I have found a way to destroy the Flying Fortress, hurry up, or you will all die." W then shouted that she was still spinning around the Flying Fortress at a very low altitude, and that she was going to make sure that each of the Aerial Fortress's ion thrusters had heat dissipation holes next to them.

"It's W, but I promised them that I wouldn't let them die." John didn't give the order, but explained to W in a tangled way.

"Uncle John! Do you think you're saving them, you're hurting them, if you can't tear down the fortress in the air, let alone you, they will die with them, and in the end no one will be able to live. W shouted at John, but she had already circled the Flying Fortress, and she had confirmed that there was a heat dissipation hole next to each ion thruster.

"W, you give me a moment, you make me think about it." John was so entangled that he fell into deep thought after saying this.

"Don't think about it, the giant cannon of the Flying Fortress will be charged immediately, and once that thing is fired again, everything will be over, you don't want to watch more than 20,000 people of the Resistance Army being burned alive!" W said this almost angrily, she could hardly understand what John was thinking, and in this time of crisis, it was difficult for her to understand what John was hesitating.

"Okay, I see, I'll order it now, I'll have the Starstripe Subject come to your aid now." John said with a deep breath.
