After thinking about multiple plans, Zhou Tiehu and others felt unsatisfied. With the current strength of the Yanhuang clan, it was not too difficult to capture the Galaxy Fortress. The question was how much price it would cost. Now, it was the last battle before the end of the War against the Tianhu Empire (not that it was almost the same). If the losses in front of the Galaxy Fortress were heavy, it would be really not good-looking, and the soldiers under his command also had family members. Therefore, Zhou Tiehu and others had these proposals. It was just because each of these plans would have to lose at least hundreds of military groups. Such a huge loss was something that Zhou Tiehu was unwilling to pay.

After half a month, Zhou Tiehu, Guan Tiebing, Shura in black, Ouyang Tielong, Zhang Zeshan and others racked their brains when they were trying to conquer the Galaxy Fortress, but they gained nothing. Suddenly, a soldier reported: "Commander-General, Generals, a fleet is coming from the rear." It seems that the rear sent people to support it, it should be that hateful guy Sun Tiejian.

When everyone saw the person standing on the bridge, they were very surprised: "Second brother, aren't you hiding on the Winged actress to do research? Why did you come here suddenly?" "I thought I would come." Qian Tiexin laughed and said.

Zhou Tiehu laughed and said, "Second brother is here, I guess there will be good news for us." "Just count the fifth brother the most. You know that I have good things to come here this time, but you guys have to invite me to drink afterwards." "That's for sure. As long as the second sister-in-law approves, it's okay for the second brother to drink more. I can afford it." Zhou Tiehu laughed. "Fifth brother, do you say that, second sister-in-law, I am a shrew?" Zhao Hongmei asked with a smile.

After everyone met on Zhou Tiehu's flagship, everyone punched each other a few times. After sitting down separately, Zhou Tiehu asked: "Second brother, you haven't come to the battlefield for many years, how could you be so interested?" "I don't think so, but when I see you attacking the fortress, I will give you a cannon."

Shura in black said happily: "What new invention did the second brother create?" "In fact, it's not a new invention, it's just a cannon. However, this cannon has taken a lot of effort to create it. It's best to attack the fortress. But the power of this cannon is too great, and I'm afraid to send it to the battlefield."

Good guns, the diameter of the muzzle is only thirty centimeters. Yes, right, it is correct. The diameter of the muzzle is only thirty centimeters, but the diameter of the gun barrel reaches thirty meters. From this we can see the thickness of the gun barrel. With such a thick gun barrel, the materials of the gun barrel are all refined by using refining tools. It can be seen that in order to refine this gun, Qian Tiexin really doesn't know how many Yanhuang clan refiners have mobilized to extract it. The total length of the gun barrel reaches 800 kilometers, which makes me feel exaggerated. The launching position behind the gun barrel is even more exaggerated. It is actually necessary to use 10,000 heavy-duty fortress-level warships of the elite Yanhuang clan to provide energy.

The fortress-class warship is Qian Tiexin's research result over hundreds of years. The liquid warship can be combined into heavy warships and has basically reached its peak, but Qian Tiexin is not satisfied. After hundreds of years of hard research, he finally successfully studied the combination mode of the fortress-class warship. This is the first time this time. Seeing a fortress appearing out of thin air, everyone took a breath. The Yanhuang clan is becoming more and more perverted.

After a day of busy work, all kinds of preparations have been completed. Next is the creation of the shell. A meteorite planet as big as one thousandth of a moon was sent into the array map of the fortress-level battleship, and then activated the array map. Then, the meteorite was constantly getting smaller. In the end, it turned into a shell that was only three meters long and thirty centimeters in diameter. Everyone felt heartbroken when they saw this shell. The material composition of this shell was probably not far from the material of the neutron star in the black hole.

After loading the bullet, all the engines of the fortress-level battleship were activated. This was not enough. Qian Tiexin also had to add an additional array map of 100,000 Yuanqi arrays prepared by him. He used countless immortal stones to provide enough energy. Although the energy situation in the cannon could not be seen, just seeing the countless engines and the array map of 100,000 Yuanqi arrays, you would know how much energy is contained in this cannon.

After aiming, after Qian Tiexin's "fire", the shell was bombed out, and the entire shell flew towards the Galaxy Fortress that was 20 million kilometers away at a speed close to the speed of light. It will take more than a minute to hit the fortress. This is the benefit of the physical cannon. There is no resistance in space. Therefore, the distance that physical cannon cannon can fly is close to infinite. Therefore, this cannon does not have an ordinary main gun but only has a range limit of three million kilometers.

When the shells have not hit the surface of the Galaxy Fortress, and there are still dozens of kilometers, a huge pit has been created on the surface of the Galaxy Fortress. When the shells are shot into the liquid metal layer, the liquid metals are bounced away by the spin force carried by the shells themselves, forming a vacuum channel, which does not stop the shells at all. When the shells hit the armor under the liquid metal layer, the solid alloy armor is penetrated like tofu in front of the shells, and cannot be blocked at all.

The shells were half a minute, so even the armor layer as thick as 8,000 kilometers could not stop the shells from penetrating through it. The shells kept bombarding all the armor and hitting the inside of the fortress. At the same time, they also penetrated dozens of layers of internal structures, and then fell to the ground with all their strength. After the shells with huge mass fell to the ground, they also pressed through countless layers of structures, almost pressed through the main reactor inside the fortress. If the shells were stronger and pressed through the main reactor, the Galaxy Fortress would be finished.

However, now the Galaxy Fortress is over. The liquid metal layer can provide strong defense for the fortress, but when the armor layer is penetrated, these liquid metals pass downward along the channel opened by the shell under the action of gravity. In this way, it is equivalent to a liquid metal column of more than 10,000 kilometers formed under the action of gravity. The downward impact force generated by such liquid metal columns is too strong. All the buildings inside the fortress and the layered structure cannot be blocked. Even the solid outer wall and force field cover of the main reactor cannot be blocked until these liquid metal columns blasted the outer wall of the main reactor, causing a huge explosion in the main reactor.

Even if the main reactor did not explode, the liquid metal flowed into the interior of the fortress under the action of gravity. It could flood countless places in the fortress. The armor layer of the fortress could not stop much artillery fire without the protection of the liquid metal layer. Therefore, this artillery would definitely take the life of the Galaxy Fortress, and the Galaxy Fortress is over.

With just one shot, the huge fortress of Galaxy Fortress was completely destroyed. So, can there be other fortresses in the universe stop this shot? In other words, the fortresses of other races in the universe are just like paper in front of the Yanhuang clan, and they are definitely dead one shot, which is absolutely unreasonable. Everyone looked at Qian Tiexin as if they saw a devil. Only the devil could invent such a terrible weapon.

Zhou Tiehu asked: "Second brother, what kind of cannon is this?" "This is the ultimate destruction cannon I invented. This cannon is of no use to fight warships, and the consumption is too great. It can only be used to destroy buildings such as fortresses or to destroy a planet. It is the strongest destructive weapon I invented. Fifth brother, these are the ones I can help you."

Zhou Tiehu understood that Qian Tiexin knew that the Yanhuang clan would counterattack sooner or later, and the counterattack would inevitably encounter the fortress of the Tianhu Empire. Even if the Yanhuang clan had the ability to capture these fortresses, it would have to lose troops and generals. Therefore, he specially developed the ultimate destructive cannon, such as the ultimate destructive cannon, to destroy the fortress. Qian Tiexin's invention allowed countless soldiers of the Yanhuang clan to die on the battlefield where they attacked the fortress, and they were of great merit.

Using hundreds of thousands of compression arrays and massive amounts of energy, a meteorite planet can be compressed into a shell, so that the shell has a density of nearly neutron stars. The weight of such a shell is calculated in billions of tons. In addition, the energy of the cannon will accelerate it to close to the speed of light. In this way, the shell has invincible ability to attack objects with inconvenient movement. No matter how thick your armor is, it cannot be stopped. In fact, any armor is like paper in front of such weight and speed, and it cannot be stopped at all. This is the principle of the ultimate destruction cannon.

Although the principle is simple, it is difficult to successfully create it. Even with the ability of the Yanhuang clan, it took decades to create such a sect. There were hundreds of thousands of weapon refiners used, and countless precious materials were used to refine it successfully. Moreover, the energy required to fire such a shot is also huge. Just like now, the consumption of immortal stones is calculated in billions of pieces. Generally, a poor race cannot even have enough immortal stones to fire. However, all this is worth it. Facts have proved that once the ultimate destruction cannon is out, any fortress will be slag in front of it.

The Yanhuang tribe naturally had a thunderous joy. There was no need to use a large number of fleets or sacrifices. The Galaxy Fortress was destroyed in just one shot. From then on, the wormhole that attacked the imperial capital star of the Tianhu Empire was opened, and the war was about to end. This is of course a happy thing.

However, the Tianhu Army was in trouble. When the fortress was pierced, Tianhu Tiehai and others were not inside the fortress, and there were also troops in the rear. When they heard that the Galaxy Fortress was destroyed by the Yanhuang clan, Tianhu Tiehai completely fell to his seat, and all his confidence was completely defeated, and he was completely desperate.

The Tianhu Army was almost desperate, and even the fortress with high hopes was destroyed in one shot. So, what else can they use to block the Yanhuang clan's troops? Is everything they did meaningful? No, what they did mean nothing. Even if they fought with the Yanhuang clan, they would just die in vain. All they fought was futile.

The ultimate destruction cannon defeated not only the Galaxy Fortress, but also the Tianhu Army's determination to resist. This is similar to the effect of the United States investing atomic bombs in Japan at the end of World War II, and it brings not only killing, but also a huge psychological deterrent effect.
