15 days, this is the time limit for Gu Erdan to give each other.

In the past 15 days, Gu Erdan led the generals and elite troops back to the undead realm, leaving only those miscellaneous armies to continue to wreak havoc in this world.

After all, the level of his elite troops is too high, and the consumption after crossing the plane is too great.

In addition, I didn't plan to take down the other party immediately, so it was wisest to return for a while to save energy.

According to Gu Erdan's calculations, with the efforts of skilled craftsmen across the country, 15 days should be enough for them to break through the bottleneck and make a magic crystal cannon that can damage or even kill high-level undead.

When the time comes, the two sides will officially start a decisive battle, and Gu Erdan can also use the cannon fodder to experience the power of these improved magic crystal cannons in person.

However, the plan is not as good as the change, and after 15 days, Gu Erdan did not wait for the news of the successful improvement of the magic crystal cannon, but waited for a bad news.

That is, the Blue Empire has lost all its fronts!

Gu Erdan underestimated the motley army's desire for military exploits.

After rushing to the sky for several days, but failing to take it down, this group of guys actually formed an undead death squad composed of high-level undead and took advantage of the rainy night to launch a strong attack.

In the face of the fierce raid of the high-ranking undead, the legendary blue city that will never wither fell overnight.

And then the kingdom was breached! The royal family of the Blue Empire can't win! Fucking moved the capital!

Gu Erdan, who heard the news, was stupid.

This plot is not right! The legendary final Armageddon! The legendary improved magic cannon!

How did a bunch of ragtag armies destroy them! Is it so embarrassing to call it an empire? The younger country is about the same!

The only good news is that the craftsmen who made the magic crystal cannon did not hang up, but were packed and taken away when the other party escaped.

Obviously, the other party has not given up resistance, and is still thinking about relying on the magic crystal cannon to make a comeback.

Although if this group of craftsmen died, Gu Erdan would be able to recover their souls and let them do things for themselves.

But if you are not familiar with their system, how can you make them work perfectly?

Not to mention the real core knowledge, which is absolutely in the hands of the royal family, Gu Erdan can't guarantee that he can catch all of them who control the core technology.

Therefore, if you want to quickly improve the magic crystal cannon, it is more likely to be under the command of the Azure Empire.

As the portal opened, Gu Erdan led the generals to the ruins of the capital of the Blue Empire.

As far as the eye can see, there are no more wreckage in this place, because it has been largely leveled.

To be precise, this city was not defeated by the undead motley army, but by its own people.

After they broke through the blue city and broke through the gate of the national capital, the other party actually chose to bombard indiscriminately and directly baptized the entire city.

With the magic crystals that have been buried for a long time, this series of explosions has caused the undead army to suffer a lot, and the losses are extremely heavy.

Of course, the inhabitants of the capital suffered even more.

After a round of bombing, they were basically one out of ten, and the once glorious blue capital also ceased to exist at that moment.

Coming to the imperial city, Gu Erdan led the generals to stand silently in front of a ruin.

Directly in front of him was a cannon, a magic crystal cannon that was tens of meters in size and looked very domineering.

It's just that at this time, the giant cannon has been seriously damaged, the upper half is basically blown up, and the top cover has been torn apart.

This thing was the only weapon that posed a threat to the top of the motley army's combat power when they invaded, and it once knocked down an eighth-order bone beast with a single shot.

It's a pity that because it's only a half-finished product, after three consecutive shots, this magic crystal cannon exploded directly.

As the large number of magic crystals stored inside were detonated, the controllers and soldiers in a radius of hundreds of meters were torn apart on the spot, and even the surrounding city walls were collapsed by the shock wave.

Stroking the wreckage of the giant cannon, Gu Erdan let out a sigh.

If they were given a little more time to transform, they might be able to make the perfect improved Magic Crystal Cannon.

"Forget it, since the other party has moved the capital and retreated, he still retreated with the skilled craftsmen, there must be some way to make a comeback, I heard that they went to other countries, right? What's going on over there now? ”

As soon as Gu Erdan's words fell, the White Bone Pioneer Officer next to him had already replied in a deep voice.

"Because the Blue Empire was destroyed within a month, it has completely caused panic among other countries, and I heard that they have formed a large-scale coalition army and are ready to come here to exterminate the undead."

"Well, that's good news, how is the magic crystal cannon improved?"

"It's ............ According to the informant, it seems that they did not plan to use the magic crystal cannon. ”

"Huh?"

"To be precise, the royal family of the Blue Empire who fled to other countries are unwilling to share the production method of the magic crystal cannon, and they are still fantasizing about being able to rely on this kind of technology."

The words of the White Bone Pioneer Officer made Gu Erdan's whole person blind.

"It's time for life and death, and they are still thinking about their own one-third of an acre?"

"Yes, coupled with the fact that there are a lot of troops from other countries, dozens of kingdoms combined, enough to make up a million-level army, and they don't think that this battle will be lost, so they didn't force the royal family of the Azure Empire to hand over the production method of the magic crystal cannon, it is likely that they plan to solve this problem after we solve it."

"Hey, you actually choose to confront the undead scourge head-on? Who gave them courage? ”

Grabbing the fragment of the magic crystal that had been shattered in his hand, Gu Erdan slowly clenched it.

"Inform the miscellaneous army to prepare to assemble, and send a regular army to prepare for battle, it seems that they will not wake up without beating them hard."

With a flick of his cloak, Gu Erdan led the generals to disappear into the portal.

And the miscellaneous troops scattered around, as soon as they heard Gu Erdan's order, hurriedly gathered the army and marched towards the assembly point.

Three days passed in a blink of an eye, and in the valley in the middle of the Kaidaya Mountains, the army had been assembled.

In the middle of the canyon there is a huge wall towering, and thousands of soldiers are ready for war.

And at the exit of the canyon, endless undead spread, with no end in sight.

At this time, the number of undead is no longer comparable to the one at the beginning.

Kill, transform, kill again, transform again.

All the war dead have become living corpses or walking corpses, and have become one of the lower undead.

For example, this kind of emergency resuscitation of the undead does not have soul fire, so they are not protected by the breath of death, and they do not have the ability to act during the day.

The sunlight that contained the breath of life alone was enough to kill the thin dark energy in their bodies and burn them to ashes.

It's just that this time is different, when the number of these resurrected undead reaches a certain level, the aura of death emanating from their bodies naturally converges in one place, forming a thick dark cloud above the undead legion.

And this dark cloud also blocks out the light in the sky, creating the basis for the undead to march by day.

Black clouds crush the city! The fog is like a sky collapse!

Wreak havoc! Ghosts!

That's it! Scourge of the Dead!
