Armageddon: Shelters Can Be Upgraded Infinitely

[Open the picture! 】

Inside the shelter, Lu Yan enlarged the picture on the private chat interface, and a sketch of the shelter with simple pencil lines appeared in his sight.

The initial safe houses issued by the system are uniform in both size and shape, the only difference being the ground and underground.

This simple bird's-eye view doesn't look complicated, and even people who have never done engineering can understand it clearly.

"Divide the safe house into six areas, two bedrooms, a warehouse, a kitchen, a vegetable cultivation room and a hall, separated by a wall..." Lu Yan raised his eyebrows as he looked at the design sketch. : "There are shooting holes in all directions of the six rooms, connected by steel cables, and the control center room is set up in the master bedroom..."

After about three minutes, Lu Yan turned off the picture.

Generally speaking, he is still very satisfied with some of the design concepts in this sketch. Although the area division is a bit mediocre, if the shelter is rectified according to this design drawing, the space can be used perfectly, and the most exquisite It is the self-defense system designed in the sketch!

Install long-range weapons such as crossbows and flintlock guns at the shooting holes, connect the triggers with steel cables, and connect the steel cables to each other like wires and lead directly to the master bedroom, and finally all of them are connected to a machine box controller.

Lu Yan only needs to sit in the bedroom, and he can control multiple weapons to attack through the machine box. Coupled with his talent of [seeking advantages and avoiding disadvantages] and listening to the walkie-talkie, this shelter will officially become a fortress with powerful firepower!

If the design is completed according to this concept, Lu Yan can wipe out all the enemies without leaving home when encountering a mob attack by the trio of black brothers like last night!

And what makes Lu Yan most satisfied with this design is...

The other party not only helped him design the space he currently owns, but also made a simple plan for some spaces that Lu Yan had not expanded at this time!

For example, the second floor and the third floor of the shelter will continue to expand downwards in the future, such as the watchtower that needs to be built on the ground in the future...

Although these plans are only a few strokes, the sincerity of the other party can also be seen.

"With the future development, the area of ​​more than 100 square meters in the shelter is definitely not enough. The other party can think of this step..." Lu Yan rubbed his chin and suddenly laughed: "This is probably the legendary introversion Bar!"

At this time, the high-quality steel ax in the trading field was too sought-after, and everyone was trying to find ways to satisfy Lu Yan, and Mu Qianqian's design clearly hit Lu Yan's mind.

Soon, several more private chat messages were sent, also a few design sketches from different players.

Lu Yan carefully compared these drawings, and finally chose Mu Qianqian. Her design focused on military defense and practicality, and even thoughtfully sketched out the prototype of the shelter expansion in the future. Invisibly saved him a lot of trouble. In comparison, the design concepts of other sketches naturally seem unattractive!

Opening the private chat interface, Lu Yan replied to Mu Qianqian, ready to discuss the details with the other party in detail.

But after waiting for three full minutes, Lu Yan received the other party's reply.

[Mu Qianqian: Road God, I'm sorry! I have dealt with some private matters, and I just saw the private chat message. Is there any dissatisfaction with our design sketch? 】

[Lu Yan: This design direction is not bad, but I want to explain some details in advance, my shelter has ventilation ducts...]

Soon, Lu Yan told the other party about the inherent equipment in his shelter, and also put forward some small requirements on the placement of items. After receiving a positive reply from the other party, Lu Yan temporarily decided on a transaction plan with the other party.

A day later, Mu Qianqian will come up with a complete design drawing!

After solving the design problem, Lu Yan once again set his sights on the last two trophies of this mountain trip~www.wuxiaspot.com~ Those two somewhat crude flintlock guns!

【Old flintlock gun】

【Maximum shooting range: 600 meters】

[Penetration: 4 (penetrating 5cm planks within 100 meters)]

[Explanation: This is the most basic firearm. Its accuracy is equal to that of a crossbow, and its power is several times stronger than that of a crossbow. The only weakness may be that the reloading speed is too slow...and it may explode! 】

Two flintlock guns with mottled paint leather were placed in front of Lu Yan, and there was still a faint smell of gunpowder smoke on the guns.

In terms of power alone, these two flintlock guns are not much stronger than Lu Yan's previous longbow, but what you need to know is that Lu Yan's longbow is [excellent grade], and these two flintlock guns may be just The most common and even inferior products!

This is the grade gap between weapons.

The top cold weapon of lv1 may only be on par with the lowest low-quality weapon of lv2!

This is level suppression!

[Upgrade Direction 1: Upgrade material quality, increase weapon life, and reduce the risk of bombing! Survival points 20 are required! 】

[Upgrade Direction 2: Upgrade design accuracy, increase rifling, increase range and accuracy! Requires 40 Survival Points! 】

Two different options appeared in front of Lu Yan.

"The bombing accident seems to be serious...but I don't plan to use these two flintlock guns. I plan to use stronger steel to create higher-quality new firearms, and there may be some special effects." Lu Yan looked at it. One glance at upgrade direction one, and then fall on upgrade direction two: "As for adding rifling...it seems very necessary!"

"However, it's better to be able to produce a boring knife and industrially produce rifling... In case of mass production of flintlock guns in the future, one upgrade will cost 40 survival points. Who can afford it?"
