After thinking of a number of plans, Zhou Tiehu and the others were not very satisfied, with the current strength of the Yanhuang Clan, it was not too difficult to capture the Star River Fortress, the question was how much to pay. Now, it is already the last battle before the end of the war against the Heavenly Tiger Empire (not almost), and if you suffer heavy losses in front of the Star River Fortress, it is really not good-looking, and the soldiers under your command also have families. Therefore, Zhou Tiehu and others all ignored these proposals. Just because, each of these plans is to lose at least hundreds of front army groups, and such a big loss is something that Zhou Tiehu is unwilling to pay.

After half a month, Zhou Tiehu, Guan Tiebing, Black-clothed Shura, Ouyang Tielong, Zhang Zeshan and others racked their brains to find a way to capture the Galaxy Fortress, but they gained nothing. Suddenly, one of the fighters reported: "Commander-in-chief, generals, a fleet is coming from the rear. "It seems that someone from the rear has sent someone to support, it should be Sun Tiejian's hateful guy.

Seeing the people standing on the bridge, everyone was surprised: "Second brother, aren't you doing research on the winged actress? "I thought I would come. Qian Tiexin said with a smile.

Zhou Tiehu smiled and said, "Second brother is here, there must be good news for us." "It's the fifth most ghostly, and I know that I have good things to buy for you this time, but afterwards, you guys have to invite the second brother to drink." "That's for sure, as long as the second sister-in-law approves, there is no problem for the second brother to drink as much as he wants, and I can afford the fifth brother." Zhou Tiehu laughed. "Fifth brother, you say that, second sister-in-law, I am a?" Zhao Hongmei asked with a smile on the side.

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 been to the battlefield for many years, how can you be so interested?" "I don't want to, but when I saw you coming to attack the fortress, I brought you a cannon. ”

The black-clothed Shura said happily: "What new invention has the second brother come up with?" "Actually, it's not a new invention, it's just a cannon, but this cannon really took a lot of effort to make." It's the best way to storm a fortress. It's just that. The power of this cannon is so great that I am a little afraid to send it to battle. ”

Good cannon, the diameter of the muzzle is only 30 centimeters, yes, you read it right, the diameter of the muzzle is only 30 centimeters, but the diameter of the barrel reaches 30 meters, so you can know the thickness of the barrel, such a thick barrel, and then see the material of the barrel. They are all materials refined by refining techniques, and it can be seen that in order to refine this cannon. Qian Tiexin really didn't know how many refiners of the Yanhuang clan had mobilized by Lu Dao to refine it. And the total length of the barrel reaches 800 kilometers, which is exaggerated when you think about it. The firing position behind the barrel is even more exaggerated, and it takes 10,000 heavy combined fortress-class battleships of the Yanhuang Clan's elite division to provide energy.

The fortress-class battleship is the result of Qian Tiexin's research over the past few hundred years. The liquid battleship can be combined with a heavy battleship to basically reach the top, but Qian Tiexin is not satisfied, and after hundreds of years of painstaking research, he finally succeeded in researching the combination mode of the fortress-class battleship, and this time it is the first time to use it. Seeing a fortress that appeared out of thin air, everyone gasped, the Yanhuang clan is really becoming more and more perverted.

After a busy day, all kinds of preparations have been completed, and the next step is the manufacture of shells. Sending a meteorite planet as big as a thousandth of a moon into the formation of a fortress-class battleship, and then activating the formation, I saw that this meteorite was constantly getting smaller, and at its worst, it turned into a cannonball no more than three meters long and thirty centimeters in diameter. Everyone felt chills when they saw this cannonball, and the material composition of this cannonball was not far from the neutron star material of the black hole.

After loading, all the engines of the fortress-class battleship were all started, which was not enough, but also the formation diagram of the 100,000 Yuan Qi Array prepared by Qian Tiexin and the use of countless immortal stones to provide enough energy. Although he couldn't see the energy in the cannon, he could only see the countless engines and the formation of 100,000 Yuan Qi arrays to know how much energy was contained in this cannon.

After aiming, after Qian Tiexin's "launch". The cannonball was blasted out, and the entire cannonball flew at nearly the speed of light towards the Galactic Fortress, which was 20 million kilometers away. It will take more than a minute to reach the fortress, which is the advantage of the physical cannon, there is no resistance in space, so the distance that the physical cannonball can fly is close to infinity. Therefore, this cannon does not have the range limit of only three million kilometers of ordinary main guns.

When the shells did not hit the surface of the Galaxy Fortress, there were still dozens of kilometers away, and a huge crater had already formed on the surface of the Star River Fortress. When the shell hits the liquid metal layer, the liquid metal is blown away by the spin force carried by the shell itself, forming a vacuum channel that does not stop the shell for half a minute at all. And when the shell hits the armor under the liquid metal layer, those solid alloy armor is pierced like tofu in front of the shell, and it can't stop the shell for half a minute, so even the armor layer with a thickness of 8,000 kilometers can't block the penetration of the shell, so that the shell has been blasted through all the armor and hit the inside of the fortress, and at the same time, it also penetrates the internal structure of dozens of layers, which is the first to fall to the ground. And after the cannonball with huge mass fell to the ground, it also crushed through countless layers of structure, almost crushing through the main reactor inside the fortress. If the shells were a little stronger and crushed through the main reactor, then the Galactic Fortress would be finished.

Now, though, Starship Fortress is finished. The liquid metal layer provides a strong defense for the fort, but when the armor layer is penetrated, the liquid metal is gravity that follows the passage opened up by the shells and goes straight down. In this way, it is equivalent to the formation of a liquid metal column up to more than 10,000 kilometers under the action of gravity, and the impact force generated by such a liquid metal column is too strong. All the buildings inside the fortress, no matter how good the layered structure is, could not stop half a minute, even the solid outer wall of the main reactor and the force field cover, until these liquid metal columns burst through the outer wall of the main reactor, causing a huge explosion in the main reactor.

Even the main reactor did not explode. The liquid metal flowed into the interior of the fortress in a constant stream of gravity. It was enough to flood countless places inside the fortress. And the armor layer of the fortress could not block much artillery fire without the protection of the liquid metal layer. Therefore, this cannon is definitely the life of the Galaxy Fortress, and the Galaxy Fortress is finished.

With just one shot, the huge fortress of the Galaxy Fortress was completely destroyed, so could there be any other fortress in the whole universe that could stop this cannon? The fortresses of other races in the universe are just like paper paste in front of the Yanhuang clan, and they are definitely killed one by one, and there is no luck. Everyone looked at Qian Tiexin's eyes, as if they had seen a devil, only a 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 useless to fight warships, and the consumption is too great, it can only be used to destroy buildings such as fortresses or destroy a planet, and it is the strongest weapon of destruction I have ever invented. Fifth brother, that's all I can help you with. ”

Zhou Tiehu understood. Qian Tiexin knew that the Daoyan Huang Clan would counterattack sooner or later, and the counterattack would inevitably run into the fortress of the Heavenly Tiger Empire. Even if the Yan and Huang clan wanted to capture these fortresses, they would have to lose their troops, so he specialized in researching the Ultimate Destruction Cannon, a terrifying cannon with lethal power, to destroy the fortresses. Qian Tiexin's invention allowed countless soldiers of the Yanhuang clan not to die on the battlefield of attacking the fortress, and the merit was immeasurable.

Using hundreds of thousands of compression arrays and massive amounts of energy, a meteorite planet is compressed into a cannonball, making the cannonball have a density close to that of a neutron star, and the weight of such a cannon is calculated in billions of tons. Coupled with the energy of the cannon, it accelerates to close to the speed of light, so that the cannonball has an invincible ability, used to attack objects that are difficult to move, no matter how thick your armor is, you can't stop it, in fact, any armor is like paper paste in the face of such weight and speed, and it can't be stopped at all. This is how the Ultimate Doom Cannon works.

Although the principle is simple, it is extremely difficult to make it successful, even with the ability of the Yanhuang clan, it took decades to create such a one, and the use of hundreds of thousands of refiners was as many as hundreds of thousands of people, and countless precious materials were consumed before it was successfully refined. Moreover, the energy to be consumed to fire such a cannon is also massive, just like now, the consumption of immortal stones is calculated in 100 million pieces, and the average poorer race is not even enough immortal stones to fire a cannon. However, it was all worth it, and it has been proven that as soon as the ultimate destruction cannon comes out, any fortress in front of it is scum.

The Yanhuang clan was naturally thunderous, without using a large number of fleets, without paying a lot of sacrifices, just one shot destroyed the Star River Fortress, from then on, the wormhole that attacked the imperial capital of the Heavenly Tiger Empire was opened, and this war was about to end, which is of course a happy thing.

However, the Heavenly Tiger Army is in big trouble. When the fortress was pierced, Tianhu Tiehai and the others were not inside the fortress, and there were also rear troops to sort out. When he heard that the Star River Fortress was destroyed by the Yanhuang Clan, Tianhu Tiehai completely collapsed on his seat, all his confidence was completely defeated, and he was completely desperate.

The Heavenly Tiger Army was almost desperate, and even the fortress with high hopes was destroyed with a single shot, so what else could they use to block the Yanhuang Clan's troops? Is there any meaning to what they have done? No, what they have done is meaningless, even if they fight with the Yanhuang Clan, they will only die in vain, and they will only fight in vain.

The blow of the Ultimate Destruction Cannon defeated not only the Galactic Fortress, but also the determination of the Celestial Tiger Army to resist. This is similar to the effect of the United States dropping atomic bombs on Japan at the end of World War II, bringing not only lethal injuries, but also huge psychological deterrent effects.

Tianhu Tiehai raised his head and said, "Tieyi, order the whole army to surrender, no need to fight anymore." Tianhu Iron Wing's whole body was shocked, and he shouted: "Brother Hai." "Go ahead. The war is over, and there is no point in fighting any longer. "Yes, Brother Hai. (To be continued......)
