Thundered!

In a series of thunders, the earth cracked, and many aliens were killed by the thunder.

Compared with fire, the lethality of thunder is greater, and when a burst of thunder falls, the number of aliens is reduced.

The rest of the aliens were disrupted and fled in all directions, but thunder still fell from the sky, and the aliens continued to fall.

Although this killing array still has an attack range, the attack speed is so fast that many aliens have not fled.

Even aliens who escape the attack range will be attacked by humans or gas bombs, and it is difficult to leave safely alive.

The thunder kills fast and goes fast, and soon after the end of the fire dragon killing array, the power in the thundercloud is exhausted, and it disappears.

The last army was already retreating, they were all birds, and they were retreating very quickly.

But at this moment, a dense crowd of aliens appeared on the horizon, and nearly 20,000 aliens were killed.

"Reinforcements have arrived!"

When the retreating commander saw this, his expression was overjoyed.

Sou!

A flash of lightning appeared, turning into a huge black-feathered thunder eagle.

"The warriors of the Black Feather Thunder Eagle alien race obeyed the order and attacked the human formation with all their might!"

Obviously, a general offensive is about to be launched at this moment.

"Everybody's back!"

Xiao Mu also let the people who were hunting scattered aliens outside retreat, and now the number of alien armies has increased too much, and the masters of less than five hundred people can't stop the aliens at all, and they will be easily surrounded and killed.

At this moment, the only thing that can deal with the alien army is the power of the formation, and last time he was able to destroy nearly 10,000 alien races, this time the number of aliens has doubled, but the formation has also been improved, and he is completely confident to deal with it.

Zhang Tianying and the others looked at the alien race, and retreated to the Heavenly City with a heavy heart.

For so many aliens, they didn't have much faith to stop them.

"It's time to fully activate the power of the formation!"

Xiao Mu flashed and landed in the core area of the formation, where there was an array disk, in which ten immortal crystals were placed, and the light was already dim at this moment.

He took out a full forty new immortal crystals and put them in it, which was all the inventory, enough to launch four killing formations in one go.

Pinching and urging, the entire Heavenly City's formation shone brightly. At the same time, there is a dangerous aura emerging in all directions.

The formation barrier, which had originally become thinner due to the consumption of power, was restored in an instant, and the thickness had increased a lot.

Outside the city, the alien commander who had killed him found that the power of the defensive formation had increased a lot, and his expression was a little uneasy.

The Black Feather Thunder Eagle commanded the fastest, his eyes were sharp, and he flashed a look: "Something is wrong!" ”

"After consuming it for so long, how can there be such sufficient strength."

The commander of the Qingjiao royal family was also a little surprised, and had a bad feeling.

"Oops, there are killing formations in four places!"

The blood-eyed white ape's pupils shrank, and he found that around the Heavenly City, there was a dangerous aura.

"It's not good, we fell for it, and they still have a killer hand!"

The Black Feather Thunder Eagle guessed something, and his eyes became more and more ugly.

"Retreat first, save your strength!"

The commander of the Qingjiao royal clan chose to retreat without hesitation, and the Black Feather Thunder Eagle had already moved.

But at this moment, it was too late, behind them, a wall of energy formed by the formation rose to the sky, merging with the formation barrier of the Heavenly City, forming a cage that locked the alien race in it.

The alien panicked.

"Hmph, this wall won't be too strong, attack directly!"

The Black Feather Thunder Eagle Commander slammed directly into the formation wall, making a muffled bang.

"Want to go? Leave some lives behind. ”

Xiao Mu watched the movements of the alien race, and the seal in his hand kept forming, and a tornado that reached the sky formed in the alien group, carrying a sharp cutting force, like a meat grinder, cutting the alien race within the range into pieces.

This is just the beginning, leaving the position, the fire dragon reappeared, and the alien race originally avoided this position and would not be directly attacked.

However, Xiao Mu couldn't change the position of the gossip for the time being, but he could let the condensed killing array force move, and under his mind, a thousand zhang fire dragon approached the area where the tornado was.

Roar!

The fire took advantage of the wind, and suddenly the fire dragon became larger, and the power became more ferocious, rushing into the alien race, shaking its head and tail, and hundreds of alien races died.

For a while, the wind and fire moved together, and the blood-eyed white ape clan who were mainly attacked was miserable, they were not fast in the first place, and they died the most at this moment.

The forces of the other two clans were also under attack, and in Ze Position, a large number of water droplets condensed out of thin air, and then accelerated, falling towards the Frog Jiao Royal Clan and the warriors of the Frog Jiao Royal Clan within the range.

Puff puff!

These raindrops contain amazing penetrating power, more terrifying than bullets, and the attacked aliens can't stop them by a single look, and blood holes appear on their bodies, and they are even killed by dense raindrops.

This is the fourth killing array in addition to Wind Kill, Thunder Kill and Fire Dragon Kill, Flying Rain Kill, and Water Attribute Attack.

Water was originally a supple thing, but under the power of the formation, water contained powerful energy, and instead turned into a terrifying killing weapon.

This time, the soldiers of the Qingjiao Royal Clan died the fastest, they were faster than the blood-eyed white ape, but in these raindrops, they were helpless, even if they went to defense, it was difficult to resist for too long.

The Black Feather Thunder Eagle was all birds, and because of its fastest speed, many of them quickly dodged the killing array and began to attack the formation barrier that closed their retreat.

Thundered!

The thunder kill followed, and one after another thunder slashed, no matter how fast the birds of the Black Feather Thunder Eagle Royal Clan were, they couldn't be faster than the thunder, even if they dodged in advance, but the void was already filled with a large amount of mist, and under the power of thunder, it was impossible to completely dodge it, and many subordinate races also suffered.

Fortunately, some of the Black Feather Thunder Eagle royal clan has wind and thunder attributes, and Destruction Thunder has a certain resistance, and can still dodge.

After they converged, they quickly broke through the outer formation wall and escaped smoothly.

In other places, there were also some who, under the leadership of the Fifth Order, broke through the escape gate with the killing array and left the range of the formation in embarrassment.

Xiao Mu didn't care, as long as he could hunt most of the alien races, it would be difficult to stop these escapees, unless he took out another forty immortal crystals and strengthened the formation walls blocking the alien races on the periphery several times.

It's a pity that the forty immortal crystals just now have basically used up his inventory, and it is already very good to be able to activate the four major killing arrays at the same time, and it is already very good to destroy more than 20,000 alien races in combination, and it is impossible to keep them all.

Wind Sweep Kill and Fire Dragon Kill, Flying Rain Kill and Thunder Kill, under the combination of two and two, the power has increased a lot, and the alien race is like a lamb to the slaughter, under the power of the killing array, it keeps dying.

The killing didn't last long, about 10% of the aliens fled, and the rest were left behind, and the battlefield gradually quieted down, and there were a lot of alien corpses on the ground.

Click.

The immortal crystal in front of Xiao Mu cracked, the light dimmed, and there was not much power left in it.

He is still very satisfied, this time he killed nearly three times as many aliens as last time, and the key is that the human race has won again!
