Doomsday Game: I become stronger by staying at home!

In the level 1 shelter, Su Yi also lit up several technology projects, all of which only cost survival points.

But now in the level 2 technology tree interface, Su Yi saw some level 2 technology projects, lighting up not only costs survival points, but also requires a small amount of [electronic components] materials.

Although the amount of cost is not much, a single project only requires a few electronic components.

But once too many technology projects need to be lit up, these costs accumulated together are also a lot.

"The technology shelter is really a deep pit. It lacks points and materials. It is much more difficult than other shelters."

Su Yi sighed deeply. It just so happened that the mysterious existence did not remind everyone when they first chose the shelter.

Even Su Yi himself felt it was difficult. He could not imagine how uncomfortable it would be for the other survivors who did not have sufficient supplies if they chose to upgrade the technology shelter.

"At this point, I can't re-select the shelter category. I can only grit my teeth and continue to develop."

"Level 2 technology projects must be turned on. There are some level 2 technology rooms that I must build."

"First focus on buying these technologies. At least after buying the technology, there are related technical data to enter the research room, which can effectively improve the research ability of research talents. Maybe it can also allow them to continue to break through the talent level."

Su Yi considered comprehensively and found that although the investment in the technology shelter is a lot, the return is also huge, far exceeding the shelters of other categories.

After some consideration, Su Yi quickly bought several technology projects.

[Basic thermal weapon production technology]: 3000 survival points + 20 units of electronic components are required to light up; after lighting up, the shelter can build [thermal weapon firearms production line room], [thermal weapon bullet production line room], [automatic guarantee of ammunition supply for related shelter weapon modules].

[Intermediate Power System]: 2000 survival points + 5 electronic components are required to light up; after lighting up, it can provide more power resources, which can support the operation of more scientific and technological equipment and production lines.

[Intermediate Autonomous Water Resources System]: 2000 survival points + 5 electronic components are required to light up; after lighting up, it can provide more self-generated water resources, and at the same time has the perfect purification effect on most different water sources.

[Intermediate Scientific Research and Exploration Ability Improvement]: 2500 survival points + 2 electronic components are required to light up; after lighting up, the autonomous scientific research and development speed of the scientific research room can be improved faster, and the benefits of talents going out for exploration can be improved more.

[Agricultural Automation System]: 2000 survival points + 3 electronic components are required to light up; after lighting up, a fully automated agricultural room can be built to improve the food supply capacity of the shelter, and a fully automated agricultural cultivation system can be realized without human labor.

[Basic Mechanical Processing Equipment]: 1500 survival points + 5 electronic components are required to light up; after lighting up, all shelter rooms related to production can be built, providing the necessary core mechanical support for the production line, and at the same time, basic tools and parts for daily mechanical industrialization can be created.

[Communication and Network System (Regional Network Version)]: 2000 survival points + 3 electronic components are required to light up; a regional network communication system can be established inside the shelter to create a complete intranet system module to increase the speed of personnel message transmission; at the same time, it provides research assistance for electronic informationization and can provide basic computing power for all intelligent modules.

[Energy Reserve and Management System]: 2000 survival points + 5 electronic components are required to light up; a resource management module system can be laid in the shelter to ensure the long-term stable operation of the shelter and improve resource utilization. At the same time, a small amount of emergency resources and energy can be self-generated in an emergency state of resource scarcity.

......

After purchasing these necessary technology projects, Su Yi reopened the construction interface and quickly bought several shelter rooms that he had previously taken a fancy to.

[Machining Room]: 2000 survival points; place basic machining equipment, produce mechanical tools, parts and machine tool assembly lines.

[Ammunition Manufacturing Room]: 2000 survival points; configure various types of basic ammunition production lines to ensure the stability of ammunition supply.

[Weapon Manufacturing Room]: 3000 survival points; configure various types of basic thermal weapon production lines to ensure the production and maintenance of firearms and individual weapons.

[Energy Storage Room]: 2000 survival points; uniformly store and distribute shelter materials and energy modules, configure resource intelligent planning system, and configure energy emergency module.

[Basic Farmland Planting Room-Automation]: 2000 survival points; 2 types of agricultural planting items can be selected, and edible crops can be cultivated automatically.

[Communication Command Center-Regional Network]: 2000 survival points; configure regional network communication system to improve information transmission efficiency, and can mass-produce various basic communication equipment.

[Defense Bunker]: 1500 survival points; can be placed anywhere in the shelter (no vacant room required), build a single-soldier defense bunker, can provide basic weapon defense and shooting holes, and have weak air defense capabilities.

"Oh, it's really expensive."

After Su Yi finished building, he couldn't help but sigh: "Not only do you have to light up the corresponding pre-tech projects, you also have to buy the corresponding technology rooms."

"Just for the weapons, it's not enough to just buy the technology projects, you also have to buy the corresponding rooms."

"It seems that 2000 points can be done, but it takes at least 4,000 to 5,000 points to get it done."

Su Yi took a deep breath, and he looked up at the rooms in the main building that were shining with golden light. Many of the renovated rooms had been renovated.

In the open space outside the main building and on the rooftop, there were also defensive bunker modules that could accommodate 2-3 people.

Although this batch of expenses was not small, the shelter was also qualitatively improved.

"With these technologies and room supplements, my shelter has basically achieved true self-sufficiency, and has a higher defense capability against the enemy."

"Tsk tsk, my building is becoming more and more like the standard of a military base."

Su Yi smiled, and now what he had to do was much simpler.

Let Jiang Xiaoci arrange more people to collect materials in the city, especially materials such as iron, copper, and aluminum, as well as basic chemical materials for gunpowder and things containing these.

As long as there are enough materials, the production needs of ammunition can be met.

Of course, if these materials cannot be found, it doesn't matter. Each production room will self-generate part of the required materials every day, but the amount is not large, and it cannot fully cover the size of Su Yi's 500-man army.

"There shouldn't be many places in the city that have these things. The army also took away a lot of supplies and resources when entering the Doomsday War."

"Forget it, I'd better spend some more points to buy some. This money can't be saved."

Su Yi opened the points store, with a clear goal, and directly found the materials category.

After the upgrade of the level 2 shelter, the purchase categories in the points store have increased a lot, and materials for making ammunition can also be purchased directly in the points store.

Su Yi directly waved his hand and spent a huge sum of 20,000 points to buy a large amount of production materials for different new rooms to use, and even bought a lot of seeds for planting.

After doing all this, Su Yi counted his remaining points.

"There are still 236,365 survival points!"

Su Yi took a breath: "Damn it, I clearly feel that I have spent a lot, how can there be so many left!"

Su Yi carefully calculated that he had spent more than 50,000 survival points after tossing for a long time?

Su Yi quickly opened his construction interface and technology tree interface, re-examined, and repeatedly checked whether he had missed anything.

He checked again and again to make sure that he had bought the most important things.

Reconsidering the entire gathering place, there was nothing particularly urgent.

Supplies, survival, defense...all kinds of areas required for the development of the shelter have been considered in place.

At this point, Su Yi even felt that he could seriously consider using the remaining points to sprint to the level 3 shelter!

"I can't spend it all, I can't spend it all!"

Su Yi sighed: "So, this is the feeling of being rich?"

While other survivors are still suffering from insufficient points to upgrade the shelter, insufficient points to build rooms, and this and that.

Su Yi has already achieved the first stage of point freedom, with so many points that he doesn't know how to spend them!
