9 p.m. on January 25, 438 A.D

Inside the sealed container on the side of the camp, several orcs are undergoing the baptism of co.

Anna is on the container, and the temporary welded transparent viewing window can clearly see the situation inside.

One of the orcs had already spat foul and collapsed to the ground.

The other three orc warriors were also listless, half-sitting on the ground, dying.

"Effective?"

Looking at the window, Ergou said happily.

"It worked very well, it worked in a few minutes!

It seems that the body of orcs is more sensitive than that of humans.

After the body mutates, the price of simple physical enhancement is still very high.

Of course, it has something to do with the relatively small space for us to do experiments, which is why the speed is so fast.

During the war, to achieve such a degree, the ventilation ducts of underground buildings need a lot of processing and modification, and the amount of work is not small! ”

Anna is not tall enough, so she stepped on the cargo box on the side at this time and talked to Ergou.

"It's okay, it's nothing more than the air inlet and outlet in the building, we first produce and release CO at the air inlet, and the carbon monoxide in the building reaches a certain concentration and blocks the air outlet.

When the effect appears, the troops can enter to save people, and in terms of engineering quantity, it is just the inlet and outlet airway covers, and the switch of the air duct fan, right? Ergou said his opinion.

"The actual situation is not as simple as Dog Shu Huang said, such an important base, the fresh air system is not child's play!

The minimum standard of the original construction is also the three preventions, and the poison gas filtration alarm system must be there.

Before we do it, we need to dismantle the filter device, and in addition, the intelligent alarm assembly of the system also needs to send someone to find and destroy it! ”

Anna said what she knew, important information to be aware of in her actions.

"Hmmm! We'll have detailed information before we act, and the Resistance should know the exact location of the siren! Is there anything else to keep in mind? ”

The second dog man looked at Anna seriously, and I have to say that Zhang Haijun sent Anna to help him really help, although Nana was a little nonsensical many times.

At this moment, the beep bracelet came with a report from Captain Li Yang.

"Brother dog! The occupation of the warehouse area has been completed by eighty percent, but we are in the northwest region, encountering stubborn resistance from the enemy, and it seems that the orcs are protecting something! ”

"Is it difficult to fight? Safety first, if it doesn't work, withdraw it! Our reinforcements have arrived, and now we are not afraid to expose the base, we have the ability to hold the warehouse base! ”

Ergou is still worried about the safety of his teammates.

"The orc infantry is not enough to see! However, there are several orc mechs, the same ones you captured before, and the number is still increasing.

I've ordered to stop the attack, gather all the mechs, and surround the area! Waiting for your next instructions! ”

Li Yang calmly reported.

"Don't act rashly, the coordinates are sent, and I will go to support immediately!"

Ergou directly turned off the communication, then quickly equipped the mecha and turned to Anna Dao.

"Nana help me install it, jet power mod!"

When you are at the base, the installation of the mecha module is automatically completed by a workbench, but at this time, there is no equipment, so you need other mechas to help you manually install it.

"I'll go too!" "Nana will help me install it too!"

Anna was clamoring to go, and the eighteenth sister was already equipped with a mecha and was ready to travel with the second dog.

"Okay, since that's the case, let's all go out, grab a few orc mechs and come back, the defense task of the camp will be handed over to Captain Liu Yulei, and the sword brothers will also go, everyone bring the hunting net!"

Time was pressing, the enemy situation was unknown, and Ergou did not stop him.

Soon, five mechs, two silver, one pink, one black, one purple, two tall and three short, appeared on the roof of the warehouse, all equipped with jet-powered backpacks with X-shaped folding wings.

In the dark night, without waiting for the second dog to speak, Anna's slightly shorter pink mecha opened its wings, ran and jumped beautifully, with a long tail flame, and flew from the roof to the airspace northwest of Sara City.

The two silver mechs of the Sword Brothers set off after them, and the last to arrive was actually protecting the airspace in front of Anna.

Ergou, who had completed the acceleration on the roof, was just about to jump and find the northeast airspace outside Sara City, which seemed to be abnormal, and Ergou, who was about to reach the edge of the roof, turned around and spewed out a huge tail flame, and stopped his body.

At this time, the eighteenth sister who followed Ergou to help run, the purple mecha, had already flown out, and asked Ergou suspiciously in mid-air.

"Brother dog?"

"It's okay, you go first, I still have something to do!

Li Yang's troops eliminated the orc infantry, covered Anna and a few people, and tried to capture the orc mecha as much as possible!

Eighteenth sister, you use laser cannons to cover them in high places.

Stay safe, don't fight, I'll be there later! ”

Ergou was in the channel and gave instructions to everyone.

Then on the rooftop, the strangeness of the northeast airspace was observed, and the mecha radar did not warn, but the two dogs clearly saw that in the air, two black shadows were flying rapidly towards Sara City.

Ergou had a bad premonition in his heart, picked up the FQJ2000 behind him, and pointed in the direction of the black shadow.

"Bang bang" is two shots, and the second dog fires a monitor, and in an instant, the monitor arrives at the established position, and the clear picture is transmitted back when it starts to work.

"I'm rubbing! What is this Nima? The orcs really have a back hand! ”

The black shadow moving at high speed in the air turned out to be two huge black wyverns with wings that looked the same as the Glowing Lake Monster, only larger in size and with a pair of exaggerated leather wings.

Flickering their wings and flying through the air, their long hanging tails paddling the air behind them, the two dragons approached Sara City as fast as they could, as if there were orc warriors on their backs.

It's getting more and more interesting!

At this time, the warehouse area attacked by the dog team had already sounded fierce gunfire and repeated explosions, obviously there was a war over there, Ergou had to find a way to drag or kill these two new enemies, and in an instant Ergou made the decision to attack.

"Bang bang bang!"

Ergou was crawling on the roof, the heavy sniper in his hand was like an assault rifle, continuously pouring bullets, and just when the two flying dragons, from the northeast, were about to fly into the sky above Sara City, they were hit by Ergou's repeated accurate blows.

Both of them retracted their huge wings and protected their bodies and stagnated in the air, but the scene that the two dogs expected to kill the flying dragon in the air did not appear at all!

Ergou clearly saw that his bullets easily penetrated the wings of the two flying dragons, but the bullets that attacked the head of the flying dragons had no effect at all, how could this be possible, at this time, the distance between the two sides was less than eight kilometers, at this distance, their own weapons light armored vehicles, or armed helicopters could be easily destroyed, but these two dragons? What is the body made of, the defense value is so high.

The body can't move, just pierce and knock off the wings, the heavy sniper in the hands of the second dog, and a magazine bomb poured out, and under the accurate shooting of the second dog, the bullets were all accurate and tricky, hitting the bone nodes on the thick leather wings of the dragon hovering in the air.

This move really worked, and the two giant dragons with injured wings fell directly to the ground in a strange manner, and then the high outer wall of Sara City blocked the view of the two dogs.

Ergou previously launched the monitor, but due to the snow slope on the ground, the monitoring could not be monitored.

When his own bullet hit the wyvern's skeleton just now, Ergou seemed to see a spark appear, which is almost impossible if it was a living thing.

It doesn't matter much, since he shot down the flying dragon, Ergou naturally wants to go forward to check, get up and put away the heavy sniper and fix it behind his back, pick up the shotgun, run and jump to turn on the jet engine, and a few catapults are on the roof of Sara City, and quickly rush to the northeast.

"Pepper, how's your battle going? Watch out for enemies in the other directions, I'll go to the walls now! ”

Unlike Anna, who directly used to fly, Ergou used the roof of the building to keep bouncing, which was relatively more energy-saving, and at this time, Ergou was moving quickly while caring about the battle situation on the eighteenth sister's side.

"Everything is going well, two enemy mechs have been captured, but the orc infantry are charging with madness and fearlessness, and it is estimated that it will take some time before the battle is over.

As Captain Li Yang said, what are these orcs protecting?

Did you find anything about that? Need my help? ”

The eighteenth sister was on the roof of a building in the northwest, covering her own troops on the ground with laser cannons, not close, with her back to Ergou, obviously she didn't know what Ergou was doing just now.

"I'm fine, be careful, I'll help you later!"

As he spoke, Ergou had already approached the outer city wall, on the roof of a building, jumped up again, and a huge tail flame erupted from behind him instantly, and Ergou's altitude in the air at this time was close to a hundred meters, and he was about to fly over the city wall.

Soon appeared in the field of vision, at the foot of the wall on the ground, two dragons that fell into the snow pit, and there were two orc mecha standing on the side, obviously the guy who rode on the dragon before.

Ergou's heart is not good, because the cunning enemy is obviously waiting for his own adventurousness, at this moment the two flying dragons are staring at it with their eyes, and the two dogs that appear in mid-air instantly open their bloody mouths, and the two mecha on the side are raising multi-barreled cannons and aiming at Ergou.

"Bang bang bang!"

Knowing that it was a trap, the shotgun in his hand began to fire continuously in mid-air, and at the same time, many nozzles on his body were all opened, and he began to act in the opposite direction, falling backwards rapidly, almost instantly.

"Roaring !!!"

A giant dragon let out an earth-shattering roar.

"Spit !!"

The other dragon spewed out a cloud of orange flames from its mouth, and that wasn't the end.

"Bump Bump!"

The multi-barreled cannons in the hands of the two orc mechs began to strafe fiercely, and the rapid torrent of metal directly formed a barrage in the night sky, and quickly swept towards the two dogs in mid-air.

The roaring dragon was obviously not to set off the atmosphere, it roared casually, it seemed to be some kind of sonic weapon, and at this time, in mid-air, the two dogs who fell rapidly had a headache in the mecha.

And the second dragon, the puddle of dragon flame that spit out was even more terrifying, directly piercing the thick city wall in front of it, and shooting at the two dogs in mid-air, that terrible power, if it hits, I am afraid that the two dogs wearing mecha will also be directly vaporized in an instant, and there is not even scum left.
