Royal Calendar Era January 25, 438 7 am

An unknown fire and inexplicable attacks caused the orc troops in Sara City overnight.

This should have been the time of day when orc troops gathered out of their nests.

But now, in Sara City, except for a few key positions, there are almost no figures of orc warriors.

Obviously, after a night of trouble, most of the enemy troops returned to the camp to rest.

Since this is the case, Ergou doesn't have to guard the rooftop. In fact, there is a real-time monitoring by monitors, Ergou no longer needs to monitor himself.

So what should I do next, rest, kill the enemy, or continue to investigate?

After repeated calculations and deductions overnight, Ergou found it difficult to come up with a perfect combat plan.

The troops are limited, and our side cannot directly occupy Sara City in a short period of time.

In Sara City, it is even more unrealistic to go and go for a long travel battle without being discovered by the enemy.

Once the enemy is alarmed, the consequences will be unimaginable.

Furthermore, there are too many important facilities in Sara City, but there are not many places to start tempting and killing. In this Sara City, it can be said that all buildings are extremely important to Ergou. Needless to say, various strategic material production plants are self-evident, even the warehouse area has huge wealth for Ergou.

It can be said that every time Ergou destroys a part of it, it means that he loses more wealth. Obviously, Ergou has long regarded Sara City as his private property in his heart.

In addition, there are a large number of human prisoners who need to be rescued, with less to more, and property must be protected so as not to injure the masses. This severely asymptotic number of combat troops of the two armies has made Ergou feel a little nervous.

The area of ​​Sarah City is not large, with a large population and a large variety of high-tech production with complex technologies. It also requires the integration of self-sufficiency and extensive material production. Confidentiality requires that the above-ground buildings have strict floor height restrictions. So the conclusion is naturally that the underground building part of Sarah City is as huge.

As soon as he thought of this, Ergou walked down the roof and returned to the goods station. Neibajie and Anna were not sleeping. They were still using their existing resources and working hard to make bombs. Several boxes of finished products were already placed behind them.

"I'm back. Thank you for your hard work, yo~ there are many results. Aren't you letting you two rest? You are disobedient!" Ergou, who entered the door, said as he walked.

"How dare we rest? We are facing a orc army of hundreds of thousands, so we are just following it! Let's come earlier, otherwise Sister Lai Jiao and I will probably not be able to handle it in a few days!"

Anna was chewing chocolate in her mouth, complaining, and was still assembling a bomb in her hand.

The eighteen sister is making some simple fried foods, packing medicines, two beauties, one big and one small, and happily cooperates. This situation gives Ergou an illusion that her mother takes her daughter to make dumplings.

"How are you doing there? There is nothing new to the enemy, right?" Sister Eighteen was concerned about the situation in Sara City.

"Ah, there's no big problem. The orc army has been struggling all night, and most of them are resting at this time.

However, three freight airships were set off just now, and it was probably transporting the cargo to other bases.

I pressed a few monitors on it. You guys are busy first. I will check the underground floor to see if I can find some military information that is beneficial to us." Ergou was ready to leave after he said that.

"Don't you need some breakfast?" Sister No. 18 said with concern.

"Let's take some emergency capsules first. Before the reinforcements arrive, I will do my reconnaissance work as much as possible. At this time, the orcs are exhausted. I should take the opportunity to harass the enemy."

As Ergou said that, he had disappeared from the fire stairs.

......

Ergou looked inward from the transparent observation window on the door at the fire escape exit on the first floor. As Ergou expected, there was no enemy guarding him. Using the permissions obtained by Anna before, Ergou easily opened the door and walked in.

The smart ceiling light illuminated, and a square hall with huge space appeared in front of Ergou.

The center is a transparent circular guard room around it, and it seems that there are weapons inside.

It is hard to imagine that the careless orc garrison was in vain here without worry.

There are a large number of small trams parked in the surrounding area. Now this floor is a passage dedicated to personnel. These trams are used to facilitate personnel to quickly pass underground.

There are four deep tunnels in the four directions of this hall, with no head at first sight, no one passing by, and no lights, which are dark and a bit terrifying.

There are also landmarks and famous brands on the walls on the exit side of each tunnel, which are detailedly marked with the location and distance information that can be accessed, such as 2km of the Central Research Institute and 5km of the nuclear power plant.

The thick dust on the ground shows that the orcs have not used this facility for a long time. If the orcs have not used or even defended the entire underground transportation network, wouldn't it be perfect? ​​It would not be so smooth in cooperation with Ergou's combat plan?

Ergou quickly got on a stadium car, and there was only one start button on the dashboard, steering wheel, brake, and accelerator. It was easy to operate. Ergou tried to press the start button. The equipment was intact and it was lighted up at a glance.

After installing a self-defense weapon at the door, Ergou quickly got into the driving seat of the field car, stepped on the accelerator and drove to the east tunnel. The 5km of the nuclear power plant shown on the sign was the area where the explosion occurred last night.

Not to mention that the car is quite fast, at least at least 60 kilometers per hour, but the two-person stadium car that Ergou chose casually is really small. He is wearing a mecha and is driving a small stadium car at this time. The picture of driving in the tunnel is incredibly funny. It looks like a big bear riding a child's tricycle.

Since he was underground, Ergou didn't care about it and turned on various detection equipment of the mecha, thermal imaging, active radar, and life detectors.

The equipment in the tunnel is working normally. Wherever Ergou's yard car drives, the tunnel lights up accordingly.

Thinking of his mentally retarded enemy, giving him such a big flaw, and thinking that he could kill hundreds of thousands of orcs without bloodshed, occupy Sara City and take it for himself, Ergou was so excited.

Ergou, who was driving a small car, actually hummed a song proudly, but Ergou, who had lost his memory, didn't know what song he was subconsciously humming.

A few minutes later, just as Ergou was so excited that he didn't know why, he hummed a small song and stepped on the accelerator into the engine. The top-heavy small field car was almost flying.

The tunnel lights in front did not turn on in advance as before, and the visual distance was instantly shortened. Ergou instinctively wanted to slow down when he found a bottomless pit on the road dozens of meters ahead.

Damn! Ergou thought it was not good, and he stepped on the brakes in an instant, but Ergou drove too fast before and was wearing a heavy power mecha. The huge inertia was not so easy to stop. He was about to fly into the ditch with his people and cars. At this time, the mecha also sounded a harsh danger alarm.

In desperation, Ergou quickly turned the direction on the right side. It might be better if he didn't turn the direction. This direction was originally head-heavy, and each person and a car separated directly. Then two loud noises sounded in the tunnel.

The car crashed into the tunnel wall on the right, and Ergou was thrown out directly, and he fell to eat shit. Ergou, wearing a mecha, maintained a protruding position and slid on the ground for more than ten meters. When he was about to slide into a big pit, Ergou reached out to hug a huge rock next to him, and almost stopped.

He was careless, careless, scared the baby to death! Looking at the bottomless pit beside him, Ergou sat up and calmed down his emotions. Sure enough, the arrogant soldier would be defeated. Isn’t it just humming a small song and just doing this?

Turn on the mecha lighting, and the tunnels on the side of the big pit were all blocked. Damn, no wonder the orcs are no longer guarding underground, and love is a dead end!

The small field car on the side overturned to the ground, and the wheels were still spinning.

Ergou, whose mecha had a lot of paint lost, sat in the spot in frustration, and was so angry that he thought he could easily win with the help of this underground passage. Looking at the amount of earth filling the tunnel, he had to dig for a few days even if he dispatched thousands of people? I was so angry that I opened my mask and got some breathing!

Take a deep breath, exhale~ huh? Not to mention that the air in this tunnel is good, open the mecha mask and take a few deep breaths to adjust your mood. Ergou soon calmed down and the air was cold~

Cool, cool?

What does this mean? Such a large-scale underground building must have a complete ventilation system, including submarine bases, elevators, all underground buildings in Sara City, and even above-ground buildings, well!

With a flash of inspiration, Ergou immediately stood up, wearing a power mecha, and easily straightened the car. Fortunately, the stadium car was not a big problem, and it was also possible to drive the tires a little crooked.

The mecha two dogs, like a big bear, got on the car again and drove back in the ground car. Unlike when they came, the big bear with scarred bodies on the bike no longer hummed songs. The speed was also extremely slow, and the car with crooked tires had a rhythm of bumpy up and down.

Originally, a small military stadium car was the simplest version of the traffic auxiliary tool, and there was no shock absorption system at all. Ergou in the mecha was confused for a while. There was no way. This time, the action did not bring the power to the chassis, so you can't run back.

Ergou, who was dying up the bump along the way, carefully observing the surroundings and above the tunnel, trying to find the entrance to the ventilation system.

Ergou was impressed when he came and saw a large fan on the top of the tunnel. However, most of these fans ensure air circulation in the tunnel. If you are lucky, you may find air intakes nearby.

It was about to return to the starting point, and Ergou got nothing except the large fan.

The bumpy little car and Big Bear combination finally returned to the guard room. Well? If I were an architect, I would definitely send air in the center of several tunnels, right? And installing fresh air ducts here, it can also take into account the huge elevator system and freight submarine base, which must be nearby.

As soon as he looked up, Ergou suddenly realized that the above of the guard room was not connected to the building ceiling, and there were rows of air-exhaust grilles on the ceiling.
Chapter completed!
