"That's it, well, it's Shu Xiao's fault, there are traces of low blood on the ground in front of you!" The second dog noticed something unusual.

This freshness coincides with the time when Huang San fled, there is not much blood, obviously Huang San carried out emergency treatment when he fled. Let's take a look at the submarine! The eighteenth sister, who came up to check the blood stains on the ground, analyzed.

After a long trestle, the three of them finally came to a dock, and two cargo submarines, one large and one small, were docked on both sides, and the reason why they knew at a glance that this was a cargo submarine was that these two submarines were very different from the conventional perception of attack and even the appearance of strategic submarines.

At this time, in the observation of the power mecha of the people, the various data of the observed submarine were directly and accurately displayed.

A large submarine and a small submarine, the large one is 140 meters long and 10.6 meters wide, and the small one is 70 meters long and 5 meters wide, and the appearance is much the same, except for the rudder with a high protrusion at the stern, there is a wide flat deck covering the entire upper layer of the submarine, which is obviously used to place cargo.

On the flat deck, there are no buildings, not even equipped with weapons, and a pair of rudder wings are installed on both sides of the hull, and the submarine is used to transport goods, which is very uneconomical compared to surface ships.

Following the bloodstains, several people passed the iron ladder connecting the dock to the submarine in the water and boarded the small cargo submarine.

"There is no one on board, I have obtained control of the submarine!"

Saying that, Anna, who was at the front, opened a secret door hidden in the middle of the deck of the submarine.

"With Nana here, it's really twice the result with half the effort, otherwise we will be difficult to find this entrance, and we can use this submarine when we go back, right?" Ergou sighed.

"Of course, this entrance and exit is too small, and it's inconvenient to wear a mecha!" The three of them had already arrived at the open hatch, and looking at the small hatch, Anna hesitated.

"Then I'll go in, you guys wait outside!" As he spoke, Ergou had already withdrawn from the mecha.

"Don't worry, Shu Huang just wants to check the evidence that Huang San escaped on this submarine?

I think I've found it, and besides whatever data you need about the submarine, I can give it to you.

I don't think it's necessary for us to go any further! ”

Anna had already looked inside the submarine through the monitors inside the submarine.

"So powerful? If you said it earlier, then I won't go down, what evidence did you find? Let's talk about the data of this submarine! "The second dog of Yang Yang has entered his mecha again.

"Submarine wheelhouse, with bloodstained broken clothes. I looked at it and confirmed that it was Huang San who was stabbed by the sword brothers that day, and there was almost nothing to say.

The standard pre-war Osfin Empire technology product, so I cracked the control system is also simple and abnormal, this small boat is equipped with a six-core fusion core drive, and the diving depth is no more than 50 meters, which is actually more suitable for surface transportation.

Need no more than ten people in the boat, of course, it is my control, I am enough, the cargo hold in the boat, it is estimated that human slaves, can carry 600 people at a time, the water surface is full load displacement of 4500 tons, the underwater speed is less than 20 knots, and now there is no cargo inside! Anna casually said what she knew.

"Well, it seems that this Huang San is very likely to be still in Sara City.

This cargo submarine, such a big guy, has an energy supply similar to our mecha?

Speaking of the chicken ribs of the submarine transportation performance, it reminds me of the orcs wanting to open the surface waterway, obviously the orcs do not have too many transport submarines, and will not use such uneconomical submarine transportation. Ergou seems to have discovered the problem again.

"That is, the enemy has large surface ships, so that the enemy needs to have large surface ships for maintenance and docking, and even production capacity.

In this way, no matter where the enemy is in the world, at least in the Osfpu continent, and even in our northwest region, there will definitely be a large port base and even a shipyard. The eighteenth sister also quickly thought of the problem.

"Well, we have a base canal, and there are a few traditional port towns downstream to the north, especially the historic city of Armstrong at the mouth of the sea.

With the No. 1 shipyard under the umbrella of Northern Heavy Industries, which was the second largest in the empire at the time, it seems that there is also a big war waiting for us there. Ergou realized the seriousness of the problem.

"Armstrong before the war, but it was a giant city with a population of more than 20 million, and the orcs were capable of occupying it?" Anna is also aware of the big problem of the problem.

"After the war, the population of Armstrong City must have decreased sharply, but in any case, if the orcs really control it, the size of the army will definitely not be less than one million, right?" As soon as the second dog thought of this, he felt a little chill down his spine.

At this time, in the city of Sara overhead, there are no less than 200,000 orc defenders waiting for Ergou, thousands of miles away over the sea, there are also enemy air helicarriers, and now there is one more, Armstrong City, millions of orc troops?

"The sword has finished inspecting the building, let's go!

Nothing unusual was found, and the base had obviously been wiped out by the garrisons of Sara City, but it would not be difficult for us to restore it in the future.

There are also no less than 40 transport submarines that have sunk in the dock, and it is estimated that they can all be restored.

That's a big boost for us, let's go to Sara City now, right? ”

Hundreds of thousands of orcs couldn't scare Anna, and she couldn't wait to find chocolate.

"Hmmm! Let's meet up with the Sword Brothers first, and the freight elevator is working normally, right? Let's take the fire escape! "Ergou needs to determine the operation of the elevator.

"Normal, let's go~" Anna started the mecha and ran like a whirlwind.

On the northernmost side of the submarine base, the mech reconnaissance team came to a huge hatch embedded in the rock, which had a cargo elevator gate connecting to the underground submarine base, and a slightly smaller metal door for a fire escape on one side of the gate.

The five mechs walked in directly, needless to say that this was a staircase, and everyone could only choose to climb the stairs on foot at this time for the sake of concealment and safety.

"Before the war, the city of Armstrong had a population of more than 20 million! What does the orcs have to take there? "Anna is also aware of the big problem

"Armstrong must have lost a lot of population after the war, but if the orcs controlled it anyway, the size of the army must not be less than a million, right?" The second dog felt a little chill down his spine at this thought

At this time, there are no less than 200,000 orcs waiting for Ergou overhead, and there are enemy airship motherships over the sea thousands of miles away, and now there are millions of Orcs in Armstrong?

"The sword has finished inspecting the building! Let's go! There is nothing unusual, the base has obviously been cleared by the garrison of Sara City, but it will not be difficult to use the recovery power in the future, and it is estimated that no less than forty submarines sunk in the dock can be recovered! That's a big help for us to get to Sara City, right? "Anna can't wait to find chocolate

"Hmmm! First meet with the sword, the elevator is running normally, right? Let's take the fire escape! "Ergou needs to determine the operation of the elevator

"Normal! Let's go~" Anna started the mecha and ran like a whirlwind

On the northernmost side of the submarine base, the reconnaissance team came to the huge hatch embedded in the mountain rock, which is the door of the freight elevator connecting the underground submarine base, and on one side of the gate is the door of the fire escape, the reconnaissance team walked directly in, needless to say that this is a staircase, and the reconnaissance team chose to walk at this time in order to conceal safety!

Since the city of Sara is located on the main road at an altitude of more than 4,000 meters, it is located on the Osbhai continent, the highest altitude of the first ladder, the underground cargo submarine base, even if it is deep underground, the altitude is 3,500 meters.

The connection between the two places requires an underground super elevator that spans a height of 500 meters, and at the same time needs to transport a large number of goods.

The giant elevator consists of a huge circular freight elevator in the middle, plus eight small fan-shaped passenger elevators built around the freight elevator.

The most powerful thing is that the huge freight elevator in the middle can usually be divided into four medium-sized freight elevators to run independently, such as encountering giant goods, four elevators can run at the same time to form a super large freight elevator.

It is conceivable that the amount of work involved in the construction of this super elevator is huge, and it can be said that the scale of the elevator alone exceeds the amount of earthwork in an underground base of King Stan.

The spacious fire escape is a circular staircase that surrounds the entire cylindrical elevator shaft, with fire doors on each floor, and an emergency fire shelter room is set up in sections.

At this time, the mecha reconnaissance team of five people, walking side by side on the wide fireproof staircase is still more than spacious, the architectural style and materials are the same as the underground base, and the second dog even suspects that it is built by a construction team.

"I regret that I didn't bring the momentum to the ground, when will this staircase be climbed!" A disgruntled Anna shouted first.

"At a height of five hundred meters, this circular staircase spans at least fifty floors, right? We have more than five kilometers of stairs to climb, and we are indeed a little tired, so we go up step by step, and there is a crawler-powered chassis, and we drive up directly! Ergou echoed.

"At the moment, what we're wearing isn't actually a power mech.

Strictly speaking, it can only be regarded as an armor power exoskeleton, or power armor.

If the Osbhai Empire was still there, with the Empire's strong industrial strength as the basic support, I would be willing to develop a real power mecha with a larger body size and more advanced performance.

This mission requires mecha diving, which is obviously not good for bringing a powered chassis and a jetpack, but with a submarine in the future, it will be much more convenient to come again! The eighteenth sister quickly accepted the reality, and the figure jumped, speeding up and flickering in the stairwell.

A few people complained, the task was in their bodies, the speed was still extremely fast, and they kept a high degree of vigilance to move forward, and after five minutes, they completed the long fire escape climbing through.

The exit is in front of you, through the transparent observation window on the door, you can see the outside world directly, and the two dogs cautiously close to the observation window to look at the outside world.

"Safe, thermal imager detection, no enemies around!" With that, Ergou opened the door and walked out.

Anna and the eighteenth sister also followed out, and the sword brothers installed a pistol self-defense system and an infantry mine behind the fire ladder door, respectively, and then followed the two dogs.
