January 25, 438 A.D. at 11 a.m

After cleaning it all up, and even cutting off his hair all over the ground, burning it clean, Ergou equipped his mecha and returned to the camp.

Anna, the eighteenth sister hadn't even rested yet, and when she saw the second dog coming back, her face showed a happy expression.

"Why did you go for so long? Why are all your mechs broken? Is there any danger encountered? ”

"Dog! How many bombs did Anna make? That's enough to blow up half of Sara City, and when the support forces bring the detonating device, everything will be in place! ”

"Oh my God? Nana, enough is enough You two don't do it first, I'm okay Little Pepper, I found a network of underground ventilation pipes extending in all directions below, encountered the resistance, and there was a little fighting!

They don't trust me, we need to find an opportunity to launch an attack and gain the trust of the Resistance!

With their cooperation, the military operation in the city of Sara, I am sure that it can be successful. ”

Looking at the bombs all over the ground, Ergou was stunned.

"What's the plan?"

The eighteenth sister was not tired, wearing a combat uniform, not only did not cover the slightest beauty of the eighteenth sister, but it looked full of wild temptation.

"I can't talk about the plan, originally I just wanted to wait for the support troops to come, and rely on drones to drop explosives in a disorderly manner, endlessly consuming the living force of the orc troops.

Now I decided to change my tactics and first try to work with the Resistance.

Taking a step back, without the support of the Resistance, I would have sent troops to seize the vast underground ventilation network of Sara City.

In order to carry out a sneak attack on Sara City, does Nana have any explosives that can be used now?

From now on, let's make Sara City chaotic! "Ergou is really impatient.

"With the materials at hand, I can only make simple, chemically time-lapse fuzes.

I'll make it, and you both can install it for me!

We'll be able to set off fireworks in a moment, haha! ”

When it comes to sabotage, Nana, like all bear children, has an indescribable penchant, and of course Nana's destruction is infinite.

Ergou quit the mecha and joined the bomb assembly team, revealing Ergou's big bald head, of course.

"Ahh Your hair? Two dogs? Wow! Dogs? Why is your face so red? Are you stimulated by something? Your head is so bright, it feels like the entire warehouse has instantly increased the lighting level?"

For the new shape of the second dog, Anna and the eighteenth sister exclaimed one after another.

"Ahem! Get a hairstyle and welcome our upcoming Sara City victory!

Let's get started, let's speed up the bomb production! ”

Ergou was embarrassed to cover up and prevaricate, and he couldn't really tell them that he was broken by a fart and died of shame! Ergou's scalded face turned even redder at this time.

Explosives, the bomb has already been manufactured, and the work at this time is to assemble Anna's newly made time-delay fuse on the bomb.

With the addition of Ergou, the bomb assembly work is faster, and the large and small bombs are quickly assembled.

In less than twenty minutes, behind the three of them, there were bottles and cans of all sizes.

"Nana, I understand your timing and bomb?

That is, the bottle is filled with explosives, the neck of the bottle is plugged with corrosive material, and then filled with a corrosive solution and sealed.

When the corrosive solution corrodes the material at the neck of the bottle, it explodes when it comes into contact with the explosives at the bottom of the bottle, right? ”

Ergou, who had just finished assembling a bomb and waited for Anna and Sister Eighteen to deliver materials to herself, hugged a large bomb made of a huge transparent bottle that had been assembled relatively early, and observed it carefully.

"That's right, Shu Huang is smart, you can understand it at a glance!"

Nana didn't raise her head, and replied to Ergou, her hands were still quickly completing all kinds of manufacturing, and her fast arms left only the afterimage of the Dao in front of her short body.

"How long have you been waiting, and why do I see that most of the materials in this bottle have been corroded?"

Looking at the transparent bomb, Ergou was a little puzzled, and the eighteenth sister beside him sent a large number of bombs waiting to be assembled.

"Don't worry, my calculations are very accurate, with a delay of forty minutes, and the error is no more than one minute!"

Nana buried her head and continued the movement in her hands.

"Shenma? Nana! Are you going to blow us up? ”

Hearing this, the eighteenth sister and the second dog on the side were not calm in an instant, dozens of soil and bombs behind them, and they were about to explode in less than twenty minutes, and then look at the three of them around at this time, a large amount of explosives were piled up, in case of an explosion, it is estimated that Sara City will be blown up by more than half.

"Oops! You two don't make a fuss, okay? Which one is this? Don't stop, you can still work for five minutes! Anna yelled in dissatisfaction.

Hearing this, the eighteenth sister stood directly on the spot, and the second dog still wanted to pretend to be calm and continue to work, but at this time, his hands were shaking disobediently, surrounded by a bunch of bombs that exploded at any time, and he was obviously frightened, so why continue to assemble bombs? I'm just afraid that it's good not to run away, and the second dog even feels itching in the lower abdomen, and he is really scared to pee.

At this time, Ergou's head was full of words, the sound of the second hand ticking, and he felt that every second was his last second in this world.

Finally, on the choice question of pretending to be forced and life, Ergou quickly chose the latter, and flashed into his mecha with a jump and shouted.

"Pepper is equipped with a mecha, and the bombs are enough, let's move the bombs to the roof of the building and launch an attack! Anna helped with the transport! ”

"Okay!"

The embarrassed eighteenth sister, hearing this, quickly equipped her mecha, dragged a small cargo box, and began to load bombs inside.

"Humph! You two, don't believe Nana, I'm going to assemble the rest!

Go first, and the rest of Nana will be delivered! ”

Nana stomped her feet dissatisfied, but she was still assembling the bomb at high speed in her hand, and the synth was really powerful.

Like an amnesty, the eighteenth sister and the two dogs in the mecha quickly hugged two large boxes of bombs, disappeared from Anna's field of vision in a puff of smoke, and ran to the roof of the warehouse.

At this time, the two of them, who were bursting with adrenaline hormones, just wanted to quickly throw all these hot potatoes to the orcs, and came to the roof of the warehouse at full speed.

It was the middle of the day, with a few hours of light, but the sky was still dark.

There were two mechas, one black and one purple, on the roof, put down the bomb box and quickly took out the bombs inside, and there were already bottles and cans of soil and bombs around them.

"How long will it take to explode? As for drones, you don't want to lose them, do you? The eighteenth sister asked anxiously.

"Damn, shit! I forgot, wait a minute! ”

In a panic, Ergou forgot to bring the drone up, and in the weapon box left by the sword, there were two small drones, both in the camp, and Ergou jumped in a flash, fell back to the warehouse stack from the hole in the roof, and ran back to get the drone at full speed.

Under the threat of death, Ergou really used all the strength of milk, tried his best to learn in his life, and quickly completed various actions, the stunned eighteenth sister on the platform, looking at the direction where Ergou disappeared, before he could react, Ergou came back, with two more small drones in his hand.

Without any pause, Ergou began to carry out, the UAV combat posture assembly, no observation pods were installed, just cargo pylons, and then as many bombs as possible.

The two UAVs are both small individual reconnaissance aircraft, and when the folding machine is opened, the wingspan is only 60 centimeters, and it can only be mounted at a time, and half of the bombs brought by the two of them.

The explosion time of the bomb was running out, more than ten minutes, and regardless of whether it would be discovered by the enemy, Ergou directly released two drones.

The drone rose directly to a height of 100 meters, and then turned to fly out of the warehouse range, at least 200 meters away, and began to drop bombs.

Visually, no enemy found the drone, and soon, the unloaded drone flew back to continue loading the remaining bombs, loaded and released, as concocted, this time the hot potato, and the remaining bombs on the roof were taken away by the drone.

Ergou breathed a sigh of relief and began to be precise, dropping bombs in the previously observed orc barracks, I have to say that the ice and snow world has a good cover for the actions of the drone, all the bombs have been dropped, and the orc troops have no signs of finding, and there is a large amount of thick snow on the ground, which provides a good protective buffer for the safe landing of the bomb.

"Whew~ It seems that the orcs are not equipped with radar, or at least not, to be able to scan the drone's defense equipment!"

Looking at the two drones that had completed all the timing and bomb drops and were returning home, the eighteenth sister also breathed a long sigh of relief.

"It's okay, it's okay! For the time being, she has not been discovered by the enemy, Anna is really too reckless, and the bomb is only delayed for forty minutes?

It's noon, the best time of the day, and dispatching a drone is tantamount to asking for exposure! ”

Ergou is obviously finally relieved.

"Say bad things about me again, keep going! I've got a lot of treasures! ”

Nana, who was equipped with a sao fan mecha, suddenly appeared at the exit of the roof, and carried an oversized ammunition box, which was obviously very heavy and full of bombs.

"Nana, can you let Shu Huang take a breath? Oh, my God! ”

Seeing the ammunition box behind Nana, Ergou, who just wanted to relax, hurriedly gave the drone that was slowly detouring at a high altitude in the distance and returning to the country in a concealed manner, and gave the command to return at full speed in a straight line.

Compared with being discovered by the enemy, it is obvious that Ergou is extremely afraid, and the bomb cannot be sent out in time to kill himself.

"This batch of bombs has no less than thirty minutes to detonate! Look at the scare of Shu Xiao, haha~! You go on, and I'll go back and go on! ”

Equipped with a mecha and still short in stature, Nana dropped the bomb box and jumped back to the warehouse.

"Huh, hey? Don't go! What to continue? Nana, enough bombs, don't make any more! ”

The helpless Ergou shouted while retracting the drone.

"There are so many containers in the warehouse, the materials are sufficient, it's too wasteful not to make bombs, it's going to be blown up anyway! We'll blow him upside down, it's dark, it's going to be long! Hahahahahaha~"

Nana's demonic laughter echoed in the mecha of several people for a long time.

"Little devil, bomb maniac!"

What Ergou can do is to fill the drone that flew back as soon as possible and fill it with bombs again, and Sister Eighteen is also helping to assemble another drone.

After a night of reconnaissance, Ergou got the accurate three-dimensional map of the buildings on the ground in Sara City, and since the bomb exploded relatively well this time, he used a drone to drop the bomb to a farther distance, and the outer city wall of Sara City was stationed, and it was estimated that there would be no less than 100,000 orc troops.

When the last bomb was dropped, at this time, the entire eastern city of Sara City, many barracks, including the outer city wall, were dropped, no less than 200 time-delay bombs were waiting to explode.

"Boom。。。 Rumble! ”

When the two drones slowly descended back to Ergou's location from a high altitude, the first batch of bombs began to explode a few hundred meters away in the warehouse where Ergou was.
