Chapter 254: Introduction to the Underground Fortress's Functions, Large-Scale Construction Begins
Tang Yu and his party were all excited when they saw the upgraded hideout.
But the most excited one was Little Raccoon.
"Hahaha, we finally moved into the cafeteria! We can finally eat the food made by Xixi every day, it's so delicious! Oh~~~ and the big guy, I can't bear to part with him!"
The upgrade time is 60 seconds.
When the light curtain disappeared, several people stood on the subway track and looked at the wall. It was the same as before, without any change, and it was still an ordinary wall.
But as Tang Yu stretched his hand to the wall, the light flowed, and the security door of the hideout seemed to emerge from the water, slowly revealing its true appearance.
Open the door and enter, everyone filed in.
It was still a spiral staircase corridor, through which you can look down at the appearance of the entire underground floor.
The area of 7,500 square meters is already more than 300 or 400 square meters of a standard football field.
So when you look at it from the spiral staircase, it looks extremely empty. The height of the underground floor is not 10 meters as calculated by Xiao Ba before, but directly changed to 20 meters.
In other words, the height from the security gate of the hideout to the ground of the underground floor is about 18 meters.
It is about the height of five or six floors.
The purpose of Tang Yu doing this is very simple, that is, to increase the upper limit of the functional area of the underground floor, leaving room for operation for large vehicles or machinery that may be encountered later, and therefore the facilities of the hideout extend downward as a whole.
As for the fact that the security gate of the hideout is too high and inconvenient to enter and exit.
Since Tang Yu has the feature of teleportation, he has rarely used the security of the hideout. His role now is more symbolic, meeting the construction conditions of some facilities.
Several people went down the stairs and began to browse and familiarize themselves with each floor.
Little Raccoon and the technician were naturally very happy that there was such a large space on the underground floor.
Tang Yu also took out the various vehicles he had previously stored in the backpack space and placed them in this space.
Little Raccoon has collected quite a lot of vehicles, including various types of vehicles, small submarines, and marine vessels, as well as many rare vehicles such as excavators and drilling machines. He is indeed a vehicle maniac.
Of course, the most important ones are the two armed helicopters.
One is the empty frame of the Mi-8 helicopter parked outside the CBS Sanatorium, and the other is the rebel armed helicopter that Octopus rolled into the sea last night.
The technician frowned when he saw the rebel helicopter.
"Boss, military helicopters generally have positioning and transmitting devices, you see..."
Hearing the technician's concerns, Tang Yu was very calm.
"It's okay. Yesterday, I encrypted the information permission of our identity information and hiding place through the Information Strategic Support Center, and shielded the signal at the same time. The rebels will not receive any signals. Of course, it would be better if you have time to modify the signal transmitter."
The technician readily agreed.
Then Tang Yu took out all the mechanical processing equipment and parts collected from the technician's nest.
Then he handed them over to the technician and Little Raccoon to sort them out.
The group continued to go down.
Leisure and entertainment area on the second underground floor.
Living and resting area on the third underground floor.
Combat command area on the fourth underground floor.
Functional resource area on the fifth underground floor.
Weapon shooting area on the sixth underground floor.
Storage and classification area on the seventh underground floor.
Ecological planting area on the eighth underground floor.
Basic support area on the ninth underground floor.
From now on, the Garden Subway Station Hideout has been officially upgraded to the Garden Subway Station Underground Fortress.
Through the panel, it can be seen that the holographic barrier perfectly covers the entire underground fortress. The successful upgrade of the underground fortress has also strengthened and optimized the infrastructure in the hideout to a certain extent.
For example, the lighting, ventilation ducts, underground water well machine room, generator room and other infrastructure are all optimized to perfectly fit the current underground fortress environment.
The underground water machine room also directly increases the water output by 30% because of the overall depth of the underground fortress.
Tang Yu took out a stack of construction drawings.
[Warehouse upgrade drawings - automated storage warehouse]
[Beverage generator construction drawings]
[Maintenance workshop construction drawings]
[Automated irrigation network construction drawings]
[Ventilation duct upgrade drawings - laboratory fresh air filtration system]
[Kitchen upgrade drawings - multi-functional restaurant]
[Entertainment room construction drawings]
[Decoction furnace construction drawings]
[Experimental field construction drawings]
[Freight elevator construction drawings] and so on.
These were all picked out before, waiting to be upgraded to the underground fortress and then directly built.
Tu Shanxi had already collected the construction materials, including the drawings and materials for the [Hideout sewer construction drawings] and [Septic tank construction drawings] needed to expand the bathroom.
Also needed to be built together are the three drawings purchased from the Doomsday Merchant, [Low-band signal collector construction drawings], [High-band signal collector construction drawings], and [Communication intelligence monitoring station construction drawings].
Different from the other three drawings.
Although many of the construction materials needed for these three facilities are high-end materials, such as phased array units, cables and other items, they are not as difficult to obtain as military supplies.
So, with Tushanxi's deliberate purchase of the most scarce food, drinking water, medicine, backpack containers and other materials, the materials have already met the construction conditions.
As Tang Yu built these drawings one by one on each floor.
The drawings in his hand disappeared, and the entire underground fortress began a new round of construction and upgrading.
These drawings are all ordinary drawings, and they can be built and upgraded in a few hours at most.
This is a rare overall improvement of the underground fortress, especially on the eve of the great flood disaster, which can be seen from the morale boost of everyone.
And Tang Yu felt that he had finally accomplished a big thing.
Now that the hideout has been upgraded, all facilities have also been built and upgraded.
The construction of the underground fortress can be temporarily stopped.
The next time the underground fortress wants to have a major improvement in strength, it is estimated that it will have to wait until the construction of the [rocket silo], [satellite remote sensing control center], [electronic warfare coordination center], [fire control radar locking system], and [missile production workshop] facilities.
The rest of the things will be left to Tushanxi and the others to handle and clean up.
Tang Yu came to the fifth underground floor - the functional resource area.
As the lowest floor of the small elevator, the elevator divides this floor into two areas, one large and one small.
The facilities in the large area are toilets, disaster coin mines, and the wine generator, soup decoction furnace, refugee treasure chest, etc. that are under construction.
The small area has only two facilities.
One of them is the [Medical Laboratory], which is also the main production facility for all of Tang Yu's advanced medical supplies.
The other facility is an epic facility that Tang Yu spent a lot of money to build - the Disaster Exhibition Hall.
