15 days is the time limit that Gu Erdan gives to the other party.

During these 15 days, Gu Erdan led the generals and elite troops back to the undead world, leaving only those miscellaneous troops to continue to rage in this world.

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

In addition, I don’t plan to take down the other party immediately, so the wisest choice is to return temporarily 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 create magic crystal cannons that can damage or even kill advanced undeads.

At that time, the two sides officially start a decisive battle, and Gu Erdan can use the cannon fodder to experience the power of these improved magic crystal cannons personally.

However, the plan was not as good as change. After 15 days, Gu Erdan did not wait for the news that the magic crystal cannon was successfully improved, but instead waited for a bad news.

That is, the Azure Empire has been completely lost!

Gu Erdan underestimated the desire for military merits by the miscellaneous soldiers.

After several days of hard attack but failed to take it down, these guys actually formed a team of undead death squads composed of high-level undead spirits and launched a strong attack on the rainy night.

Faced with the raids of high-level undead spirits, the legendary Azure City that never withered never fell overnight.

Then the capital was defeated! The royal family of the Azure Empire was unlikely to win! He actually moved the capital!

Gu Erdan was stunned when he heard this news.

This plot is wrong! The legendary final battle is here! The legendary improved magic cannon!

Why did a group of miscellaneous soldiers beat them up? Just like that, I can’t call it an empire? My brother country is almost the same!

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

It was obvious that the other party did not give up on resistance and was still thinking about making a comeback by relying on the Magic Crystal Cannon.

Although if these craftsmen die, Gu Erdan can recover their souls and let them help them do things.

But I am not familiar with their system, so how can I make them work perfectly?

Not to mention the real core knowledge, which is absolutely controlled by the royal family. Gu Erdan cannot 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 Azure Empire.

Looking around, there are all wreckage. This place can no longer be called a city, because it has basically been moved.

To be precise, this city was not defeated by the undead miscellaneous army, but was destroyed in the hands of its own people.

After they broke through the blue city and broke through the gate of the capital, the other party actually chose to bombard the entire city without any difference and baptize the entire city.

With the magic crystals that have been buried, this series of explosions has caused a lot of trouble to the undead army and suffered extremely heavy losses.

Of course, the residents of the capital suffered even worse losses.

After a round of bombing, they were basically one out of ten, and the once glorious Azure Capital was declared no longer existed at that moment.

When he arrived in the imperial city, Gu Erdan led the generals to stand in front of a ruin and remained silent.

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

However, the giant cannon was seriously incomplete at this time, the upper half was basically blown up, and the top cover was already broken.

This thing was the only weapon that posed a threat to their top combat power when the miscellaneous army invaded. He once knocked down an eighth-level skeleton beast.

Unfortunately, because it was just a semi-finished product, after three consecutive shots were bombed, the magic crystal cannon exploded directly.

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

Footing the wreckage of the giant cannon, Gu Erdan sighed.

If they were given some time to transform, maybe they could really make the perfectly modified magic crystal cannon.

"Forget it, since the other party has moved the capital to retreat, it will still be with the skilled craftsmen. I guess there is any way to make a comeback. I heard that they have gone to other countries, right? What's the situation there now?"

As soon as Gu Erdan finished speaking, the White Bone Pioneer Officer next to him had already given a deep reply.

"Because the destruction of the Azure Empire within a month has caused panic in other countries. I heard that they have formed a large-scale coalition force and are preparing to come here to wipe out the undead."

"Well, this is good news. How is the magic crystal cannon improved?"

"This... according to the informant, they don't seem to plan to use the magic crystal cannon."

"ah?"

"To be precise, it was the royal family of the blue empire that fled to other countries and was unwilling to share the way of making magic crystal cannons. They were still fantasizing about how to make them rely on this technology to rise."

The words of the White Bone Pioneer made Gu Erdan confused.

"It's time for life and death, are they still thinking about their own acre of three-point land?"

"Yes, with the fact that other countries have many military sources, dozens of kingdoms have gathered a total of millions of troops. They don't think this battle will fail, so they have no way to force the royal family of the Azure Empire to hand over the magic crystal cannon. It is likely that they plan to solve the problem before discussing it."

"Hiss, he actually chose to compete with the undead natural disaster? Who gave them the courage?"

Holding the magic crystal fragments that had been blown into pieces in his hand, Gu Erdan slowly clenched.

"Notify the Miscellaneous Army to prepare for assembly and send a regular army to prepare for war. It seems that if they don't beat them hard, they will be unable to wake up."

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

The miscellaneous troops scattered around him, as soon as Gu Erdan issued an order, hurriedly summoned the army to head towards the assembly point.

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

There is a huge city wall standing in the middle of the canyon, and thousands of soldiers are ready for war.

And at the exit of the canyon, endless undead spread out, and there was no end at a glance.

The number of undead at this time is no longer comparable to that at the beginning.

Kill, transform, kill, transform again.

All the dead of war turned into living zombies or walking zombies, becoming one of the low-level undead.

Such urgently revived undead spirits have no soul ghost fire, so they do not have the protection of death and do not have the ability to act during the day.

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

But now is different from the past. When the number of these resurrected undead reached a certain level, the breath of death emitted in their bodies naturally gathered in one place, forming a rich dark cloud above the undead legion.

And this dark cloud also blocks the light in the sky and creates the basis for the undead to march in the daytime.

Black clouds cover the city! The fog is like the sky collapses!

The monsters are raging! Ghosts and monsters are everywhere!
