Finally, it was the president of the United States who had the greatest voice on the scene who made a summary and decided on the implementation of the next plan.

"Those five alien giants are now in our earth's airspace. They will launch a massacre against us at any time, just like the massacre that invaded Manhattan, New York a few years ago."

"If we don't fight for time, it will cause millions or even hundreds of millions of casualties among our human compatriots at that time, which is definitely an irreparable bad consequence."

"Follow my command and start our last card, the doomsday nuclear bomb code named hell dog!"

President Ellis clenched his fist, his fingernails embedded in the palm, and the green veins on his wrist protruded.

Obviously, he made a difficult decision.

Listening to the "doomsday nuclear bomb" mentioned by the president of the United States, most heads of state and senior generals in the United Nations conference room are confused, and there is no clear and accurate concept of the weapon he mentioned.

However, there are a few awesome countries in the country that spy intelligence agencies know about the secret information of the hellcat nuclear bombs at the end of the United States, such as Russia and China, so the leaders of China and Russia did not show any suspicious expression when they heard the secret weapon of the "doomsday nuclear bomb". In fact, they have read the relevant reports submitted by their agents.

The director of aegis and the Secretary of defense around the president of the United States are also very clear that the so-called "doomsday nuclear bomb" in the president's mouth is a 100 million ton high-purity TNT equivalent super nuclear bomb.

It can destroy all conventional buildings with a diameter of 60 kilometers in an instant. If the outward forms of damage such as shock wave and thermonuclear radiation are included, its effective damage range can even reach 100 kilometers away, causing things within 100 kilometers to become ruins and debris.

Because it has such terrible destructive power, it has the title of "doomsday nuclear bomb"!

It took the United States more than 10 years to build this doomsday nuclear bomb with hundreds of millions of tons of high-purity equivalent level. I don't know how much human, material and financial resources were spent in the whole process.

Looking at all the military systems of the United States, in fact, there is only one. It will not be taken out easily if it is not a last resort.

Now, in such an emergency, large-scale alien forces have intruded into the territory of the earth without authorization, so the president of the United States decided to give this ultimate killer mace a try.

"Mr. President, do you really want to use that doomsday nuclear bomb?"

The Secretary of defense is fully responsible for the preservation and maintenance of the doomsday nuclear bomb, which has been stored in a secret base on the Pacific island.

President Ellis did not reply, but slightly closed his eyes and nodded in response to the Secretary of defense.

"I see..."

The Secretary of defense took out the password box of the doomsday nuclear bomb and opened the palmprint recognition system.

The launch conditions of this doomsday nuclear bomb can only be opened when the US president, the US Secretary of defense and the supreme General of the US Navy press the palmprint at the same time.

After a little hesitation, the three national core executives no longer hesitated. They pressed the palmprint hard to make the doomsday nuclear bomb system pass the biometric identification, and then quickly lost the combination password.

Then, the secret base of doomsday nuclear bomb was started and began to operate.

A nuclear missile with a length of 50 meters, the shell painted with the pattern of the American flag and the words "may God be with you" brought a mass of thick smoke and dust from the launching pit and slowly accelerated upward.

Soon it rushed out of the secret island base and rushed in the direction of the five space giants over the United States with an arc flight path!

"The nuclear missiles we launched just now are of the megaton equivalent level. Now this megaton equivalent doomsday nuclear bomb will theoretically form a comprehensive destructive power that will be more than 100 times that of the nuclear missiles launched before."

The US Secretary of defense looked solemn and frowned. "I hope this time, our last card can produce some results that are no longer disappointing!"

For a time, in the UN Security Council meeting room, the holographic communication virtual bodies of heads of state looked up at the real-time moving track of the doomsday nuclear bomb displayed on the big screen.

The doomsday nuclear bomb is mounted on a missile with extremely superior comprehensive performance. At this time, it is crossing the Pacific sea at a super speed of tens of times the speed of sound, creating a strong and harsh sound barrier wave in mid air, approaching the enemy ship in the blue sky.

According to the calculation and analysis of the weapon system, it is estimated that in another 30 seconds, the doomsday nuclear bomb carrying 100 million tons of high-purity TNT equivalent can reach the target area and detonate.

At the same time, five zetaris were on board.

In the five spacious battle command rooms, the red threat command message came from the giant ship monitoring system in charge of field marshal zitari and general Obsidian IV.

Looking at the evaluation data displayed on the big screen, marshal zitari's expression remained calm. It seemed that he did not pay attention to the earth man's 100 million ton equivalent doomsday nuclear bomb, although the power of this nuclear missile was 100 times that of the nuclear missile just now.

"Unexpectedly, there are such powerful weapons on the earth in this remote and backward corner of the Milky way. If it was an old zetari warship a few years ago, I'm afraid it would be bombed to pieces."

At this point, marshal zitari breathed a sigh of relief and raised a strange arc at the corners of his mouth, "Fortunately, before we set out, Lord mieba delivered a large amount of cosmic cube energy to the energy Bank of the five warships. As one of the six infinite raw stones in the universe, the energy contained in the cosmic cube is pure and impeccable. The shell barrier maintained by this energy can resist all powerful energy attacks, including the 100 million ton equivalent tyrannical nuclear energy 。”

But in fact, marshal zitari felt a little uneasy at the moment.

Because the energy storage capacity of these five zetari warships is limited, at the beginning, mieba used the cosmic magic cube to instill energy into them. Even if it is full, the energy storage has reached 100% full load, which is enough to resist more than 10000 million ton equivalent nuclear bomb explosions, but theoretically, its defense ability is still limited.

The explosion endurance of more than 10000 million ton equivalent nuclear bombs is roughly estimated to be equivalent to the upper limit of defense endurance of more than 100 billion ton equivalent nuclear bombs.

This means that if the earth people launch more than 100 such doomsday nuclear bombs, the situation of the zetary warship will be more dangerous.

Although marshal zitari is not sure whether there are more than 100 such doomsday nuclear bombs in the earth's military system, he is not afraid of ten thousand. Therefore, it's best to teach these earthmen a lesson and frighten these humble creatures!

"Marshal, let me go down and meet these stupid earthmen."

Ebony throat, the first-class Nianli master, suddenly slowly raised his arm and asked for instructions from marshal zitari, the General Commander.
