Since he retrieved the relevant geological and hydrological data from Mr. Kato, Wu Liang has not appeared on the island for three consecutive days. During this period of time, I have been running the seventh platform between various government units, and after changing hands, I need to go through the relevant procedures in person, and the architectural design institute has also gone several times to redesign a planning map according to the ideas in my mind.

According to Wu Liang's concept, except for the harbor part of the harbor where there are few channels for ships to enter and leave the port, the whole will be surrounded by a giant wave wall 10 meters high and 3 meters thick, and the side facing the mouth of the bay to meet the erosion of the sea current also needs to be specially strengthened on the outside with a reinforced protrusion of seven meters high and one meter wide to cope with daily wave erosion and severe weather conditions such as typhoons and tsunamis.

The internal construction plan is also completely different from the existing Odaiba, with a circle of U-shaped conjoined buildings that are attached to the inner layer of the wave wall, and a load-bearing wall will be built every 30 meters, and the wall will be made of metal frame and mixed with high-grade concrete to make load-bearing beams. The first floor, about seven meters high, will be used mainly as a large material storage and processing plant, according to the load-bearing wall as a partition to prevent fire, facing the center of the island side in addition to retaining the necessary load-bearing wall, the remaining space will be installed with a large roller shutter to facilitate the transportation of materials, each warehouse will be closed separately, no one can open without a key.

The height of the second floor will only be half of the first floor, and the first floor of the warehouse is closed separately, the second floor will be opened up as a whole under the premise of retaining the load-bearing pillars, and the use of flexible materials to divide into several service areas with different functions, such as: medical, catering, entertainment, collective activities, etc., several areas will be laid in the middle of the metal roller shutter door with hard texture and fire protection function, and the critical moment will be used to urgently close a specific area, in order to avoid the complete destruction of the gathering place due to the leakage of the dead body due to inspection errors.

The third and fourth floors will be built into apartment-style residences, and each corridor connecting from the second floor will be separated, with four households on each floor, each with a floor area of about 60-70 square meters, which basically meets the needs of normal families except that there is no gas supply. (In order to avoid fires and save fuel, a canteen will be set up on the second floor to provide meals according to the time limit.) ）

The fifth floor will be separated separately to completely cut off the connection between the third and fourth floors, and the only way to communicate with each other is through the service area on the second floor, and the fifth floor will be used as a separate integrated control platform for the garrison's daily accommodation, storage of weapons and ammunition, and monitoring of the situation on the island. In this way, although the response speed of dealing with emergencies will be slightly reduced, it can increase the risk of direct attacks by dead bodies in the garrison, and also strengthen internal monitoring to prevent some people from having untimely thoughts in addition to food and clothing, and forcefully suppress them.

The rooftop space on the top floor will also not be wasted, whether it is the installation of solar panels to make up for the power gap, or the conversion of the roof into a greenhouse vegetable garden and breeding garden, which can make a considerable difference to the gathering place.

Odaiba's existing interior space will be greatly reduced if it is renovated in this way, but there is still a small vacant land in the central part of the island that can be developed, and the creation of a three-dimensional farm will provide a supply of green vegetables and a little protein in the cluster, and a considerable number of jobs will be created. (Having something to do, something to eat, and entertainment items will meet the basic physiological needs of most people, so as to avoid the tragic consequences of internal chaos in the later stage of the high family.) ）

The port will also need to be renovated, not only to widen the existing T-shaped pier, but also to fill in two additional breakwaters to surround the existing pier in the form of arm guards, and the oil and gas storage tanks will be rebuilt on top of the new embankment to expand the storage scale and improve safety and avoid accidents affecting the whole island. The cold storage will also be expanded in its original location to store enough meat for 2,000 people for a whole year.

In addition, as the weakest point of the island's defense, a five-meter-high defensive wall will be built between the port and the residential area, leaving only two passages four meters high and five meters wide, and equipped with metal gates with rollers and slides to make up for the defensive shortcomings, and the walls on both sides facing the port will also increase the firing ports and heavy machine guns to enhance the defensive capability.

In short, according to Wu Liang's idea, it is to build the seventh platform into a super-large turtle with a hard defensive shell, as long as it is not directly submerged by the sea of dead bodies, even if there is a little infection inside, it can be carried through.

Of course, this is not very beautiful in appearance, and it is more appropriate to build a new plan for Prison Island than to build a maritime city.

In addition to the defense facilities, the drainage and sewage facilities on the island are also under Wu Liang's consideration.

Drainage and sewage issues are particularly important if you do not want to purify domestic water with polluted seawater, or if the power supply of tidal power plants is interrupted due to domestic waste. Due to the size of the land, the only solution is to load garbage on ships and dump it back on the mainland.

The 7th Odaiba as a gathering place is only a temporary expedient measure, its carrying capacity is very low, it is better to say that the supply of food and drinking water is good, but the spare parts for fuel and machinery parts will always run out one day. After surviving the initial chaos of the outbreak of the "Bullock" virus, the survivors' eyes will be on the mainland sooner or later, and it is worth taking a small risk to obtain first-hand information about the dead body.

However, in order to make all this go smoothly according to your plan, there is a very big hurdle to challenge---- that is, a nuclear bomb that will explode at high altitude in Japan and form a large-scale EMP phenomenon!

Ignoring the initial shock wave of the nuclear explosion, which was not lethal at the beginning, the loss of power due to EMP alone directly paralyzed more than half of the defense methods designed by Odaiba itself, as for the highly lethal radiation dust scattered by the wind, it is equivalent to a catastrophe, and the electricity is gone, so how to talk about air purification? There is a lot of radiation dust accumulated in the body, even if he and Sakura can't survive the time to complete the task, not to mention that if the side quest can't be completed and the reward points are not enough, there is still only a dead end.

Therefore, how to follow the mission prompts and immediately organize a team of elite men to go to the military port when the virus breaks out, snatch an Aegis ship and find a way to intercept the nuclear bomb is also one of the difficult problems to consider.
