The system is one year ahead of schedule, but it’s not the end of the world yet!

[Main Survival Mission·3]

[Task Name]: Security Barrier

[Task Introduction]: With a loyal pet and a group of trustworthy people, it is time to build a stable shelter for yourself. Find a suitable area and build a shelter where you can survive safely.

Special requirements: The shelter covers an area of ​​at least fifty acres, and the living materials inside can support at least one hundred people for one year. The walls of the shelter are strong enough to withstand at least the impact of level three ferocious beasts. There are at least five buildings in the shelter. Defensive building.

"Fifty acres, Mingyuan Community is enough. There are a total of one hundred single-family suites in Mingyuan Community. Each building occupies about an acre of land. The entire community should be more than 100 acres." Chen Mo made an estimate of Mingyuan. The size of the community, "But how awesome is this wall to withstand the impact of third-level ferocious beasts?"

[Task period]: sixty days (if it is not completed after the time limit, the task time will be doubled and the reward will be reduced by half)

[Special Tips]: Since the host obtained the top-level reward in "Main Survival Mission 2", this time we will give you a special reminder about the conditions for obtaining the top-level reward.

"Conditions for obtaining top rewards": The shelter covers an area of ​​at least 100 acres, the survival materials in the shelter can last for at least 100 people for three years, and the strength of the shelter walls can at least perfectly withstand the impact of fifth-level ferocious beasts. Have at least ten defensive buildings.

"The top reward still has to withstand the impact of the fifth-level ferocious beast? What level of wall is needed to block it?" Chen Mo felt that this main survival mission was a bit difficult.

[System prompt: It is detected that the host has started the main survival mission three. If the host subsequently opens the gift package reward, he will be able to obtain architectural drawings, building materials and other rewards. At the same time, the system mall has also opened some architectural drawings and building materials for sale. 】

"Huh, it turns out that the system will also provide architectural drawings and building materials, so you can rest assured. With the things produced by the system, it shouldn't be very difficult to find a wall that can withstand level five ferocious beasts.

I just don’t know how much material is needed. "

Chen Mo felt a little more relieved when he saw that the system would open up rewards and redemptions for construction.

Otherwise, it would be a bit difficult for him to build a city wall with extremely high defense level out of thin air.

There were no task requirements for managing the system for the time being. Chen Mo first opened the system mall and checked the sales of architectural drawings and materials in the system mall.

He found that the architectural drawings were so diverse and had everything in them.

[Shelter main building·A-level architectural drawings]:

[Drawing Description]: Using modular design, it can be assembled into buildings of different sizes according to needs. The main building has a cylindrical appearance to adapt to different terrains. The interior of the building adopts a honeycomb structure, which can withstand greater pressure. The roof is equipped with solar panels and rainwater harvesting.

[Materials required for construction]: high-strength carbon nanotube composite materials, self-healing concrete, efficient thermal insulation materials, smart glass windows, and other composite materials

……

[Fence·B-level architectural drawings]:

[Drawing Description]: The fence adopts a double-layer design, the outer layer is made of high-strength alloy steel, and the inner layer is a nano-scale protective net, which can effectively block attacks by vicious beasts. There are laser defense systems and detectors on top of the fence.

[Building Materials]: Super alloy steel, nano-scale protective net, high-efficiency energy battery, laser transmitter, other composite materials

……

[Defense Building (Machine Gun Tower)·B-Class Building Drawings]:

[Drawing Description]: The machine gun tower adopts a rotating design and is equipped with a high-speed machine gun and an intelligent aiming system. The tower body adopts a multi-layer protective structure and can withstand large attack forces. There is an energy shield generator at the top of the tower.

[Building Materials]: High-strength alloy steel, nanoscale composite armor, energy shield generator, high-speed machine gun system, other composite materials

……

[Energy facilities (solar power station)·C-level architectural drawings]:

[Drawing Description]: The solar power station adopts a spherical design and is equipped with high-efficiency solar panels on the surface. There is an energy storage system inside the power station to store excess energy.

[Building Materials]: High-efficiency solar panels, energy storage batteries, intelligent control systems, other composite materials

……

[Agricultural facilities (ecological farms)·C-level architectural drawings]:

[Drawing Description]: The farm adopts a closed design to simulate the natural ecosystem. The farm is equipped with ecological ponds, planting areas, breeding areas, etc., and adopts a circulating water treatment system. There are plant growth lights and carbon dioxide recovery devices on the top of the farm.

[Building Materials]: High-strength transparent materials, circulating water treatment systems, intelligent lighting systems, carbon dioxide recovery devices, and other composite materials

"System, you have a lot of building materials, which are themselves creations that need to be made. Are there any drawings for these things?" Chen Mo asked after glancing at the mall. He was wondering if he could get some such drawings and make them in the prosperous age. Production.

[System prompt: There is no function to sell related material drawings. If the host needs related materials, please directly use survival points or the equivalent amount of gold to purchase them. 】

Following the reply to the system prompt, Chen Mo realized that in addition to the selling price of survival points, behind each building material, there was actually a gold selling price.

"No wonder they are talking about gold as hard currency. At the end of the world, all money is useless, but gold can still be used, and can you still buy things with the system?"

Chen Mo was also quite surprised.

He immediately looked at the relevant ratios.

According to the ratio calculated by the system, 1 gram of gold is equivalent to the purchasing power of 1 survival point.

Of course, the purchase of these building materials is limited to other things that can only be purchased with survival points, and there is no additional gold as a currency.

But even so, it was a profit for Chen Mo.

I already knew that the end of the world was coming, and money was the most useless thing.

Now there is a way to convert useless money into gold and then exchange it for extremely useful building materials. It is simply beautiful.

But there is still a question: with the drawings and materials, can the building be built accurately?

Chen Mo couldn't help but ask the system: "What if I have the drawings and materials but there is no talent to build the relevant buildings? Isn't this a trick on me?"

[System prompt: Please rest assured, the host, the system can provide the host with construction robots, and the construction robots will complete the construction tasks perfectly.

At the same time, the system can also provide the host with a one-click construction function. As long as the host has relevant drawings and gathers building materials, the system can perform one-click construction for the host. 】

"According to what you mean, both of these items must be charged."

[System prompt: The host can rent three construction robots from the system for free. If the host wants to improve efficiency, it can rent a few more construction robots. For each construction robot, the host will be charged an additional 1000 survival points.

If the host chooses to use a building function, the price of the survival points required for the building will be determined based on the system's evaluation of the building's original construction time. 】

"You are actually willing to provide three units for free. You have some conscience."

After understanding the construction-related content, Chen Mo no longer worried about these things.
