Armageddon: Shelters Can Be Upgraded Infinitely

"I'll test you on a question about geography..."

"Where's your home?"

After sending these few words, Lu Yan closed the world chat interface.

Although he couldn't understand this woman's face showing off her wealth, he didn't intend to waste precious time on such meaningless verbal battles. As for his last question, it was purely teasing.

He has no plans to plunder other people's resources for the time being.

First of all, although the weapons produced by the system are excellent, they are not far ahead of everyone by a single version; secondly, his current military power is not as good as those of those masters. Danger.

After collecting all the materials and materials for expanding the ventilation system, Lu Yan started to dig a ventilation channel above the mound of the safe house.

This is a job that requires special care. Since the ventilation pipe needs to go straight to the ground, and there is a certain turning arc, it is much more difficult than the drainage channel. If it is not well controlled, there will be a danger of collapse at any time.

With the help of the crude design in his brain, Lu Yan took out stone materials every 30 centimeters down to strengthen the soft soil wall in the tunnel, and pushed forward bit by bit.

It took a full four hours before a crude stone ventilation duct was connected to the underground safe house.

"It consumed 15 survival points and 160 units of stone..." Lu Yan stood at the air vent of the safe house, wiping the sweat from his forehead, "It's very similar to the consumption of building a drainage channel!"

Excavating a ventilation duct with a total length of 8 meters and a vertical structure is definitely a job that consumes both energy and energy.

Even with the special effect of the shovel (easy to dig), Lu Yan's muscles still ached uncontrollably after doing all this.

"It seems to be pulled to the bruise...Hiss, it hurts!" Lu Yan looked at the injured leg, and at this moment there was also a burst of severe pain. In order to dig this ventilation channel, he paid a lot cost.

But standing at the vent right now, feeling the gentle breeze with the smell of grass and trees pouring in from the wilderness, Lu Yan instantly felt that everything was worth it!

[A stone ventilation channel]

[Width: 1 square meter]

[Length: 8.3 meters]

[Evaluation: A strong and excellent ventilation duct, which can make your safe house dry and keep the air circulating at all times]

Ventilation system, complete!

Lu Yan snapped his fingers, the next thing to do is to add a safety system to this ventilation duct, otherwise, in the unprotected state, this ventilation duct will be a self-service food intake for beasts wandering in the wilderness, just jump in , you can eat delicious Luyan brand fine soft steak, pork belly, big bone...

[Whether to make barbed wire? Need 1 unit of iron block, consume 1 survival point]

[Whether to make iron anti-theft windows? Requires 4 units of iron blocks and consumes 1 survival point]

[Whether to make a sealed window? Need 1 unit of wood, 1 piece of explosion-proof glass, sealant...]

Lu Yan turned on the production function, and produced three items to strengthen the safety performance of the ventilation duct according to his previous plan.

"The hole in the barbed wire...is only 0.5 cm, even a small snake can't climb in." Lu Yan picked up the barbed wire and checked it, and was very satisfied with its protective density.

Among the three products produced by the system this time, the barbed wire mesh and the anti-theft window are of ordinary quality, and only the sealed window is of excellent quality.

Lu Yan looked at the anti-theft guardrail again. It is made of twelve iron bars as thick as an adult's index finger. Among them, there are six vertical lines and six horizontal lines. They are interlaced and combined to form a "net" shape. The square gap in the middle is about two About ten centimeters, this kind of space, no adult or medium or large beast can get in.

As for the sealed windows of the last fine class...

【Sealed window (excellent) (easy to close)】

[Easy to close: when closed, it is 100% isolated from hot and cold air, noise, toxic gas, and micro-radiation attacks]

Lu Yan looked at the properties of the sealed window and felt very pleasantly surprised.

When it is closed, the safe house is completely isolated from the outside world, and any invisible harmful materials cannot get in through the vent!

"It's just that its strength is too low to resist violent damage, otherwise I really want to replace the door of the safe house with a sealed window of this property!" Lu Yan sighed, and all three products passed his assessment. Next is installation.

He directly turned on the [Upgrade] function in the survival system, and as expected, two upgrade options appeared in the stone air duct in his sight.

[Upgrade Direction 1: Increase anti-theft and anti-intrusion capabilities, need 50 survival points]

[Upgrade Direction 2: To enhance the ventilation and ventilation capacity, 50 Survival Points are required]

Putting the three items in the vent, Lu Yan looked over again, and the survival point requirement for upgrade direction 1 was reduced to 5 points.

"Start upgrading!"

When Lu Yan gave an order, blue light shone in the ventilation duct, as if a pair of invisible hands grabbed the barbed wire, the anti-theft bar, and the sealed window ~www.wuxiax.com~ and firmly installed them in the designated position of Lu Yan!

Three seconds later, all items are installed!

Ventilation system, completely finished!

Immediately afterwards, Lu Yan piled up some weeds and dead branches at the position of the vent outside to camouflage.

"Next... I'm going to build a stove, a kerosene lamp, and upgrade the walls and gates of the safe house to stone." Lu Yan rubbed his chin and carefully listed his plan in his mind.

He discovered that there was a kind of construction gene lurking in his bones, and just thinking about these things made him feel uncontrollably excited!

"I want to completely upgrade the safe house from [barely providing living space] to [providing safe and comfortable living space] before the sun sets today!" Lu Yan's eyes were firm and sparkling.

…

On the other side, in a safe house in a rock cave, a girl stared at the world chat interface on the screen with a smile on her face.

The bright sun shone in at noon, reflecting the girl's delicate and beautiful cheeks.

Bright eyes and bright teeth, a sweet smile!

If Lu Yan was standing here at this time, he would definitely be able to recognize this girl as Liu Yuanyuan who flaunted her wealth in the trading field and raged at the players on the World Channel.

But at this time, Liu Yuanyuan's face did not have the slightest bit of arrogance, domineering, and villainous look.

Her expression was full of confidence and calmness, and there was a sly smile at the corner of her mouth.

"A Yuan, what's the matter?" A tall, wheat-skinned young man came over, holding a military dagger in his left hand, and dragging a wild wolf that had just been hunted with his right hand, and asked softly: " Did that group of players take the bait?"?
