In the middle of the night, one of the elemental kings gritted his teeth and gave an order full of unwillingness: "Withdraw!" ”

There is no way but to evacuate, preserve strength, and find a way.

Elemental airships and solar chariots have withdrawn from here like a tidal wave, and around the area where the original ice city is located, a steady stream of mummies have emerged, and the number has increased exponentially.

In just half a day, the number of mummies that appeared had reached a million, with the goal of destroying everything, spreading in all directions, and this number was still increasing.

The unkillable "undead army", like locusts, occupied most of Europe in just a few days, and the elemental civilization, the sun civilization, Xiao Ling and others, watching the surging mummies, could only keep retreating.

In the past few days, the two sides have fought a few more battles from time to time, but each one has been in vain, but it is believed that these mummies have become stronger, and their own side has lost a lot of elemental envoys and sun warriors.

Whether it was the elemental civilization or the solar civilization, they all resorted to the means of pressing the bottom of the box, and only then did Xiao Ling know that these civilizations also had the ultimate weapon that was not inferior to a nuclear strike.

For example, the "Elemental Cannon" of the elemental civilization, which is a weapon that stores the five elemental energies of "earth, water, fire, wind and air" and then launches it, but the volume is too large, almost as tall as a ten-story building, and it is very troublesome to use, it has been stored in the "Elemental City" where the current power core of the elemental civilization is located, and now in order to deal with these expanding undead legions, it was temporarily transported over, and the "Elemental Cannon" hit with a blow, the power can be called devastating, and a thousand-meter peak in the distance was razed to the ground. Thousands of mummies were destroyed along with them.

After this "elemental cannon" attacks once, if you want to store enough elemental energy again, you need a group of elemental envoys to release energy, and it will take a few more days to complete the storage, so it will never be used lightly unless it is absolutely necessary.

And after using it at this moment, everyone waited quietly and nervously, hoping that a miracle would occur.

Unfortunately, the scene that appeared after that was the same as the use of ICBMs a few days ago, on the scorched earth that was razed to the ground, soon there was a gathering of matter, re-transformed into a powerful mummy, an undead army, and resurrected again.

"Not even the Elemental Cannon can destroy them, far away—" One of the elemental kings let out a desperate roar.

At the current rate of the undead legion's spread, in less than a month, the entire earth will be their world, and they can't resist it, either die on the earth, or they can only find a way to escape from here and enter space.

It's just that with the current aerospace technology of the elemental civilization, it is impossible to escape with all the elemental humans, and only a very small number of humans can escape, and when they enter the long space, it is dangerous and unpredictable, and if they are not careful, they may fall.

Despair emerged from everyone's heart, and a white light suddenly flashed in the distance, and there was a loud bang that was deafening.

However, it was the solar civilization that used the last resort and used a killer weapon similar to the "elemental cannon", which was called the "solar bomb".

This "solar bomb" is to gather a huge amount of solar energy, gather and compress, and finally release it, the power is so great, even more than the "element cannon", everyone in the distance only feels that at the end of the horizon, a dazzling sun rises, like the sun in the sky falling, the destructive energy burns the earth, and the sky is filled with a scorching breath.

Xiao Ling saw it in his eyes and was secretly surprised, the power of this "sun bomb" even surpassed the nuclear bomb with the largest yield used by human beings on the earth, which was enough to destroy all materials within hundreds of kilometers, but unfortunately, it still couldn't kill these mummies.

All means have been exhausted, everyone is desperate, and they understand one thing in their hearts, this is a doomed fate, the end of the fifth age of mankind, not human beings can stop it, these undead legions are invincible, their fate is only to perish.

"Guys, we're going back to Elemental City and report to our leader what happened here."

The three elemental kings said goodbye to Xiao Ling and Mr. Bai, they had already understood in their hearts that the only way out now was to abandon the earth and escape into the unfathomable depths of space.

This means that they will have to abandon ninety percent of their elemental humans, and only a very small number of elemental high-level people will escape.

After all, the spaceships that the elemental civilization has secretly built now can accommodate a limited number of them, and they can't carry the entire elemental human race away.

The Elemental armies began to withdraw from Europe, and airships of various sizes took off.

Xiao Ling, Mr. Bai and the others stayed, watching the sun chariots on the other side also start to move towards the distance, and they also left.

"Destiny cannot be violated, the earth ...... I can't hold it. Mr. Bai's face was full of despair.

Xiao Ling looked at the group of mummies approaching in the distance, and muttered, "Let's retreat too......"

Xiao Ling, Mr. Bai, Zhou Kesheng, Jiang Leitian, Guo Yongchang and Catres retreated in the direction of Asia together with the three battle kings.

Cattres was originally a European, but his country had perished, he had become a survivor, and now he was homeless, so he followed Xiao Ling and others, but everyone knew in their hearts that Asia was not safe, and these undead legions would soon occupy the whole of Europe, and then expand to the rest of the earth.

"Is there really no way to deal with these mummies?" Jiang Leitian couldn't help but ask.

Mr. Bai said: "The methods that should be tried have been tried, these monsters really can't be killed, as long as they can't be killed, we have no way to think of it." ”

Xiao Ling kept frowning slightly and was silent, always feeling that he seemed to think of something, but he couldn't remember.

After the arrival of the battleship sent by the Warrior Civilization, it turned out that this was the warrior sent by the headquarters to send reinforcements to the King of War, but after witnessing the horror of the undead legion, everyone had no intention of fighting, and just got on the battleship and returned immediately.

Everyone is thinking about the way back, thinking about how to escape from this earth that is about to end.

The undead legion, unstoppable.

After everyone left on the battleship, when they passed through the highest peak in the world, suddenly Xiao Ling seemed to think of something, let the battleship stop, jumped in the air, and fell on this peak.

It was once shrouded in black light, but now the black light has disappeared, and only a huge carriage lies here, quietly weathering the wind and sun, standing still.

This carriage is the part of the human race that crashed in the Death Train.

The former feather king Shi Yu and the barbarian king Xiao Han tried their best to reverse the doomed fate of mankind that was about to end.
