After Tu Changtian arrived at the front line, under his command, the entire defense line became more reasonable, and his command and combat ability was fully displayed.

Time always flies.

It didn't take long for Su Qing's army to reach the front line.

The two sides confronted each other from a safe range, and soon, Tu Changtian received a message from Su Qing, and when he saw it, his lungs almost exploded.

"Su Qing, the commander-in-chief of the Golden Domain, was ordered by His Majesty to come to conquer the invading enemy, my emperor has the virtue of a good life, although you are waiting for dirty things, but you don't want to take the life of the dog, and order me to salute first and then soldier, so I send this message, I hope that you will withdraw as soon as possible, otherwise once the attack is broken, the chicken and dog will not stay!"

Not to mention the change of heaven, it is that all the soldiers and generals of the Black Dead who saw this information were angry to death, and they were clamoring to destroy the human race one by one and give them a good look.

Of course, Su Qing obeyed Ji Hui's order to salute first and then soldier, but she didn't know how to say this, to be honest, she was born as a star thief, and she was able to make such a paragraph, which is quite good, but unfortunately she misunderstood what Ji Hui meant, Ji Hui was worried that the power of the super cannon was huge, and he had created too much killing karma, or hoped that the Black Emperor could retreat from the difficulty, and he could also waste one less shelling, but Su Qing understood that it was a salute before the soldiers, that is, to humiliate them first and defeat them.

So there was such a show.

After reading such a passage on another day, no matter how good his temper was, he couldn't bear it, so he immediately ordered the troops on the front line to fire a salvo.

Of course, Su Qing was not within the range, and this salvo naturally couldn't hit anything, but the meaning of Tu Changtian was very clear, and he resisted to the end.

"This is stubbornness! Someone, the cannon is waiting! ”

Su Qing gave an order, and a herald had already passed the order.

The whole army began to retreat, and the super cannon began to move forward slowly under the pull of the battleship, this time, not a dozen battleships, but one hundred and sixty super battleships, divided into eight directions, the giant cannon was pulled with thick iron chains, twenty battleships in each direction, this is to prevent the recoil of the giant cannon.

Although he knew that the cannon was dangerous, there was no way, if he didn't do it, the cannon wouldn't hit the enemy at all, and it would be a real waste.

And the soldiers of the Black Dead Clan and the soldiers of the Imperial God Clan within the defense line all looked at the enemy's actions strangely, although this cannon felt a bit big, but what can a cannon do?

Even if they don't fight back, let this giant cannon hit, and they won't be able to defeat this stronghold for a year!

The soldiers did not understand, and neither did the figure of the commander-in-chief.

"What are humans doing here? Why did they retreat? Is this scary? ”

In the flagship command room, a handsome man with a spar on his head said strangely.

He is the personal guard of the young man, and he is also the supreme commander of the troops of the Imperial God Clan on the battlefield, of course, the commander-in-chief of the entire defense line is Tu Changtian, they are just a cooperative army.

"I don't know their intentions for doing this, but no matter what, our goal is to stabilize the defense line and protect this stronghold, I believe that no matter what intrigues and tricks the human race has, as long as our follow-up army arrives one after another, we will not be afraid!"

Tu Changtian is very steady, and he doesn't care about the actions of the human army on the other side, but continues to strengthen the defense of the defensive line.

Soon, after a few adjustments, the Super Cannon was finally in position.

Its range is very large, so it is still outside the range of the opponent, and it can calmly adjust the position and adjust the angle, because it is pulled by the battleship, the adjustment is extremely troublesome, and it took more than ten minutes to adjust.

"Let's get started!"

Su Qing gave the order to attack.

The scientists who received the order began to work on the rear of the cannon, which was different from other automatic cannons, and could be fired at the push of a button.

Its workflow is very complicated, it has half a sun's energy crystals in it, and it is now in a highly condensed state, which needs to be activated first, and then in the process of complete activation, it cannot explode and spread, and when it is completely activated, it will be launched all at once under the guidance of a special device.

It can be said that it does not have any amplification equipment, some are just equipment to guide and prevent it from exploding in advance, its power is completely dependent on its own terrifying energy, there is no amplification at all, but this is enough, it does not need to be like other cannons, there are still requirements for cannon barrels, shells, operating principles or something, its lethality comes entirely from its own huge energy, this energy can be reduced by ten with one force, and it can destroy any obstacle in front of it.

Soon, the cannon began to be activated, and at the moment of activation, it was obvious that the entire cannon began to heat up, especially in the rear position, which began to change color slightly.

This change has become more and more evident over time.

By the end, the entire rear of the cannon had changed color, and the cannon had turned into a fiery red.

Fortunately, the material used to make this giant cannon is a special material, so it can temporarily resist this high temperature.

The entire battlefield, whether it is the enemy or the enemy, is staring closely at this giant cannon that is making strange changes, Su Qing is nervous, for fear that the giant cannon will not be able to bear it, and it will explode in advance, while Tu Changtian frowned, he vaguely felt that something was not quite right.

This giant cannon is really weird, different from any weapon seen before, as the power of the cannon increases, the energy supply time becomes longer, which is normal, the ultimate cannon of mankind Yang electronic combination cannon is a kind of cannon with a very slow energy supply, and the power is large enough, but the energy supply time with a giant cannon is too long!

A few minutes passed, and there was no launch!

Ten minutes have passed, and there is still no launch!

Twenty minutes passed, and the entire cannon turned fiery red, and the surrounding space seemed to be burned and distorted, and it still didn't fire!

Thirty minutes later, the cannon finally moved.

Rumble!

The barrel of more than 100 kilometers, the muzzle of the cannon suddenly a ball of orange-red fire drilled out, and in an instant it had already flown towards the defense line established by the Black Death Empire, as soon as this fire came out of the muzzle, it was like a wild horse that had taken off the leash, rapidly expanding and expanding, and the volume kept getting bigger in the process of flying, and soon, it had already illuminated this star field.

The two sides of the rolling heat wave can clearly feel it even through the battleship.

At this moment, everyone was shocked, and no one could say how they felt at this moment, as if they were suddenly watching a sun come into being from nothing.

Of course, at this moment, the soldiers on the side of the Black Death Empire were not only shocked, but also boundless fear.

The "sun" was approaching them, faster and faster, faster and faster, and in the blink of an eye, it had already flown to the very center of their stronghold.

It seems that such a rapid expansion can't match the speed of its expansion, and finally, it exploded, endless explosions, it seems that it can't stop, and the entire star field is bombarded back and forth, even including the defense line established by the entire Black Death Empire, and even the wormhole is not spared.

Even Su Qing's army, which had withdrawn far away, was still in a big mess by this shock wave.
