Two hours later, all the systems in the Tianji Fortress have been breached, and the electronic warfare troops of the Tianhu Army began to frantically destroy all the software in the fortress's defense system, however, before the defense system was completely breached, Sun Tiejian had already ordered the defense system to be closed, if the defense system was not closed, I am afraid that not only the software, but even the hardware will be destroyed by the Tianhu Army, and the loss will be great.

As soon as the defense system is turned off on the fortress side, of course, the Tianhu Army will immediately know that after the defense system is closed, it does not mean that it can operate normally if it is opened again, and it needs to be cleaned up before the virus and Trojan horse in the system can be re-operated, besides, as long as the defense system is turned on again, the electronic warfare troops on the side of the Tiger Army will also use Trojan horses to manipulate the defense system, so the defense system of the fortress is completely finished in a short period of time, and it has no effect.

After receiving the report from Fierce Tiger Sos, the Tiger Fury ordered: "First Army, attack. "The 400,000 Starriver-class warships of the First Army began to charge forward, starting from fifteen million kilometers away and heading towards the fortress, advancing at a speed of three hundred kilometers per second. The range of the main guns on the Starriver-class battleships has reached 10 million kilometers, and there is still a range outside, but outside the range of the main guns does not mean that the battleship has no way to attack the fortress, there is a way, that is, missiles.

"All the missiles are ready, and after a minute they attack. "In the face of fortresses, missiles are not completely useless, especially the missiles on the Starriver-class battleships, which are very powerful weapons.

Eight missile exits were cracked on each battleship, eight huge missiles flew out of the launcher, and the 400,000 warships, with a total of 3.2 million missiles, flew towards the Dimensity fortress like a swarm of bees.

The missiles equipped on the Starship-class battleships, each of which is three kilometers long and one hundred and thirty meters in diameter, are filled with the most powerful ultimate particle explosives in the Heavenly Tiger Empire, the power of this explosive is extremely amazing, each kilogram is equivalent to 10,000 tons of terrifying power, and a missile, except for about half of the fuel, the other half are ultimate particle explosives, and its number is as much as 50 million tons, and its power is equivalent to 5 billion tons** Explosives, 3.2 million missiles attack at once, and its total power is equivalent to 160 trillion tons of ** explosives, such a terrifying power is enough to destroy a planet like the earth.

How can we say that the attack distance of a missile is shorter? Of course, it is shorter than the main gun, but it is much longer than the main gun, because there is almost no resistance between the universe, that is to say, after all the fuel of the missile is consumed, it can still continue to move forward with the help of inertia, and if it is not a celestial body such as a planet in front of it, the missile may fly forever, so the range of the missile is much longer than that of the main gun, and of course, its speed is much slower than the speed of light of the main gun.

These missiles only reach a speed of 100,000 kilometers per second before the fuel is exhausted, only one-third of the speed of light, and at this time they only enter the range of 10 million kilometers of the fortress, and from this time on, the missiles fly towards the fortress with the help of the force of inertia, and the speed remains the same. Ten million kilometers, which is only a hundred seconds, is still very fast, in comparison, much faster than a battleship.

A hundred seconds later, the missile hit the Dimensity Fortress, and the huge explosion power stirred up countless liquid metal waves, setting off huge waves that soared into the sky, these huge waves were hundreds of meters high, and countless fireballs appeared on the surface of the entire fortress, and the high temperature produced by the explosion reached tens of thousands of degrees, like a small sun, such a high temperature evaporated countless liquid metals, turned into gas, and flew away under the power of the shock wave.

After the explosion, the strong light disappeared, the high temperature also disappeared, the temperature of the vaporized liquid metal decreased again, turned into liquid again, and fell back to the surface of the fortress under the gravity of the fortress itself, only a very small part of it was washed away by the shock wave too far, has left the gravity circle of the fortress, and can no longer return to the surface of the fortress, turned into small droplets solidified in space, for a while, there are countless small water droplets in the distance, the number of these small water meters is indeed a lot, but in terms of total volume, it only accounts for less than one billionth of all liquid metal。

The power of the missiles is powerful, but they have not yet been able to blow through the liquid metal layer, in other words, the only function of these 3.2 million missiles is to blow up a little liquid metal, and the rest cannot even make the fortress shake a little. Although this result was within the expectation of the Heavenly Tiger Army, the solidity of the fortress actually reached such a level, which really made the generals at all levels of the Heavenly Tiger Army scratch their heads.

Missiles don't work, so there is no need to waste them, and missiles are quite suspicious and expensive, so the First Army no longer launches missiles, but accelerates until it is within the range of the main guns.

If you want to attack more powerfully, you must get closer to the fortress, and the artillery attack at the first 10 million kilometers into the firing range and the artillery attack at 300,000 kilometers are the same, but the power when hitting the fortress is more than ten times different, so in order to save energy and increase the power of the main artillery when hitting, the First Army had to continue to move forward and get closer to the fortress.

Seeing the Heavenly Tiger Army's warships approaching, Kaigula asked, "Third brother, should we give them some power first?" "There is no need for the time being, let them get closer and try the defense of our fortress, the enemy's heavy troops are still behind, they have troops, we destroy them at all, it is nothing, it is better to fight the defense of the fortress first." ”

Approaching three million kilometers, the Blood Tiger Soul Slayer ordered: "All ready, the main cannon is charged, and it will be fired in a minute." "The main gun of the Galaxy-class battleship is quite powerful, and it is not impossible to fire it while on the move, but if it is fired in a rapid advance, the recoil of the main gun when firing is too strong, and it will cause some damage to the battleship, so if it is not necessary, the speed of the battleship will generally be reduced to a speed of 100 kilometers per second before firing the main gun.

Each battleship has four main guns, and I saw a long, huge gun barrel stretching out from the front of the battleship, and the muzzle of the gun flashed with white electric light, indicating that the main gun was being charged, and the white electric light flickered more and more intensely, and when the flicker reached the limit, a terrifying white speed of light was sprayed out from the muzzle and rushed to the fortress three million kilometers away. 400,000 warships, a total of 1.6 million strong lights pierced the void, ionizing countless particles in the universe, and if someone was around, they could smell the smell of the particles being ionized. However, fortunately, such a terrifying attack has not yet broken through the limits of space, and it has not yet reached the level of tearing space.

The fortress had already activated all its defensive formations early in the morning, and countless energies were channeled from the storage arrays in all corners of the fortress to the liquid metal layer and the armor of the fortress, ready to resist the terrifying attacks of the enemy army. Yang Tiehui's mood was very nervous, could the fortress block such an attack?

The power of the main guns of the Galaxy-class battleship has reached level 35, and 1.6 million main guns are fired in a salvo, although they are not concentrated on one point, but the overall power is terrifying to the extreme, and there are quite a few main guns that are concentrated on attacking one point, and at some points they are only afraid that they will be fired by tens of thousands of main guns at the same time, such power is too strong, and whether they can withstand Yang Tiehui's heart is really bottomless.

Three million kilometers, the power of the muzzle is thirty-five, and the power when it reaches the fortress is a little more than thirty-four, and the distance reduces the power of the main gun by a part, but when the attack point of tens of thousands of main guns reaches a point at the same time, it is really unknown whether this point can withstand it.

Sun Tiejian smiled and said: "Tie Hui, if we can block such an attack, then we don't have to worry about it in the future, if we can't block it, then it's useless for us to worry, according to your design, our fortress defense is as high as level thirty-nine, and it should be able to block it." "Third brother, theoretically speaking, the defense power of level thirty-nine can indeed be blocked, but I am afraid that the fortress will also be damaged to a certain extent. "That's okay, our fortress is made by refining weapons, and it can automatically recover from injuries, don't worry. "Listening to Sun Tiejian's words, it seems that he is the designer of the fortress. Zhang Zeshan didn't say anything in his mouth, but he was deeply impressed by Sun Tiejian's general's style, the enemy was still able to be so calm, he really deserved to be the commander-in-chief of the external operations named by Han Wenzheng, and he wouldn't be able to do it if he was replaced.

Just as everyone in the fortress was talking, the fortress was hit, countless beams of light hit the fortress, and the entire fortress was immediately shaken by the powerful energy, and the whole fortress shook, and it took a while to calm down, and the people inside the fortress were like sitting on a passenger car driving on a country dirt road, and they almost couldn't sit still. Under the impact of such a strong energy, they didn't dare to release the Yuan Shen to observe the movement outside, in this case, releasing the Yuan Shen was definitely looking for death.

From the point of view of the Heavenly Tiger Army, the main cannon hit the fortress, causing a shaking of the fortress, however, the amplitude of the shaking is not very large, countless liquid metals were evaporated, and metal gases flew away, however, from the liquid metal layer, there is an additional blue energy shield, which is desperately resisting the attack of the main gun, the blue shield looks very soft, but it vibrates like a water wave, weakening the power of the main gun little by little, after a few seconds, the power of the main gun disappears, and the blue shield basically disappears, however, just a few blinks of an eye, these blue shields return to their original appearance。

All the generals and soldiers of the Heavenly Tiger Army widened their eyes, there was no way to hurt the fortress with such a powerful attack, the defense of this fortress was too strong, it seemed that if you wanted to hurt the fortress, you still need more warships to attack together, otherwise, there would be no way to hurt a piece of paint in the armor of the fortress.

Seeing this, the Tiger Fury asked, "Bigu, are we going to press or retreat?" "Your Excellency, the enemy has not counterattacked yet, and it is obvious that their system has not yet recovered, so we should take this opportunity to attack and not let them have the strength to fight back." "Okay, the whole army is attacking. "The 1.6 million Starriver-class warships of the Fifth Front began to move forward, pressing on the entire front, leaving no reserves.
