MTL - Armageddon: Shelters Can Be Upgraded Infinitely-Chapter 9 Drains, done!
Lu Yan sat on the ground and looked at the crooked drainage channel in front of him. Although it already had the function of drainage, it was not reinforced with stone materials. Although the soil drainage channel looks very solid now, after a few heavy rains, the soil quality will be broken. If it is soaked, it will be softer, and it will collapse and block soon!
It's just that Lu Yan scanned around the trading house and found no powdered concrete for sale at all, not even the clay and adhesive used to make concrete.
"It seems that we have to use the [upgrade] function of the system."
Lu Yan called out the system interface, then looked towards the drain, and soon, two prompts appeared in front of his eyes.
[A drainage trench (upgradeable)]
[Upgrade method 1: Use stone materials for reinforcement to improve sturdiness, corrosion resistance, and easy cleaning! But it is vulnerable to destruction and requires 80 survival points! 】
[Upgrade method 2: Use plastic and stone pipes to bury pipes underground, which increases concealment, is not easy to be damaged, reduces bacterial growth, and avoids the spread of stench, but it is more difficult to clean up after blockage! 200 survival points are required! 】
The upgrade method of the drains is surprisingly similar to the placement of the safe house, both of which have two options: above ground and underground.
"From the perspective of the two options, the underground drainage channel is definitely more advantageous, but I have too few survival points now, so I have to spend all my money wisely..." Lu Yan thought for a moment, and decided to choose the first upgrade The method is to wait until there are more survival points in the future, and at worst, renovate the drainage canal.
There were only 10 units of stone left in his backpack. After taking them all out and placing them in the drainage ditch, he found that the survival points required for upgrading had dropped to 75 points.
Lu Yan rubbed his chin, he strode around to the back of the safe house, picked up some stones and put them together with the previous stones.
The survival point requirement slowly changed to 74.
"Sure enough, there is only a limit to the quantity of stones needed to upgrade the drainage canal, not the material... as long as it is a stone, it doesn't matter if it is a pebble or an ore!" Lu Yan discovered an important piece of information, which made him very excited: "Is this the case? It means that as long as I collect enough stones, my safe house can also be upgraded to stones in a short time?"
An hour later, Lu Yan picked up all the rocks within 1,000 meters of the safe house.
However, due to terrain factors, the road rock safe house is located far away from the mountains, so even after collecting all the surrounding stones, there are only about ten units.
[Upgrade method 1: Requires 70 survival points! 】
"There's no way to do this. There are too few stones around here. Just go to the trading ground to scan the goods!" Lu Yan looked at his palms that had been worn out with bleeding blisters, and then looked at the sun that had risen above his head, and it was about to arrive. He had to finish work on the drains and return to the safe house by then during the hottest part of the day or risk heat stroke.
It is the most convenient way to scan the goods directly on the auction house.
After all, Lu Yan now holds the common currency of "drinking water", and he can exchange for anything he wants.
Don't say that Lu Yan's unrestrained use of drinking water to buy various commodities is a stupid behavior, but that he can keep the water and spend more time and energy to collect stones from a farther place...
Time is also an important resource in the apocalypse.
It may take a day or two for Lu Yan to collect enough stones for the expansion of the drainage canal, and he has to go to a farther place. Not to mention the waste of time, he also needs to consume a lot of water and food in this day or two. Transaction purchases consume more!
His contribution and gain will be completely out of proportion!
What's more, in the early days of the doomsday, the price of stones, which can be seen everywhere, is very, very low, and you can buy a lot of them with just a little water.
【Seller: Lu Yan】
[Selling items: 10ml drinking water (total 1000ml)]
[Required items: 30 units of stone]
[Explanation: Buy a large number of stones, each person is limited to three exchanges! 】
After the drinking water hit the shelves, the news of the deal quickly rang.
[Player Su Chen bid 90 units of stones and got 30ml of drinking water! 】
【Player...】
Lu Yan's behavior of exchanging drinking water for stones is no less than a savior to some players who are struggling with hunger and thirst online. You must know that in the early days of the end, most players regard stones as a "resource" that can be found everywhere. Garbage, so far, there is no precedent for successfully selling stones in the trading field!
At this time, Lu Yan made a move, which naturally made many people deeply puzzled.
[Duan Xiu: The things he bought are so strange, stone... what can it be used for now? 】
[Hong Wen: Road God! My safe house is near the mine, how much more stone do you need, I contracted it myself! 】
[Li Qiunan: Ladies and gentlemen, do you think there is such a possibility... Lushen uses this method to help some people who can't drink water? After all, stone is now equivalent to garbage, who would be willing to use the most precious water source to buy garbage? 】
[Lu Shan: Of course! Lushenren are still very kind. They want to help people, but they don’t want them to have the idea of getting something for nothing... That’s why they use stones that anyone can get in exchange for water to let us know that we want to drink water. We must rely on our own efforts to fight for it! 】
[xx: The road is majestic, and the love is boundless! 】
【xx: Listen to me, thank you, because of you...】
In the world channel, a considerable number of players actually approved of this reasoning, because they really couldn't think of the use of Lu Yan's purchase of a large number of stones. Under the leadership of several rhythm masters, the world channel is full of brainless praise for Lu Yan...
As the saying goes, self-strategy is the most terrifying. Lu Yan never thought that his simple trading behavior would make so many people regard him as a benefactor, but he didn't bother to explain. After all, "prestige" is also an important resource. Although the performance in the early stage is not obvious enough, after the order is established in the wilderness and the survival is stable, UU reading www.uukanshu. The importance of com "prestige" will slowly emerge.
【You lost 1000ml drinking water】
【You get 3000 units of stone】
After the two prompts, a large amount of stones appeared in front of Lu Yan. He tried to put the stones into the drainage ditch, watching the required survival points and rewarding them bit by bit. Finally, after putting in 540 units, the survival points were fixed at 20 No more moving, no matter how many more stones are added, the survival point will no longer change.
"Has the limit been reached?" Lu Yan rubbed his chin. It is obvious that the stones needed for the drainage channel have reached the upper limit. If we want to continue to reduce the survival point, we need to add some concrete, and even after adding concrete, the survival point is impossible. Reduced to 0, because the system also needs "labor fees" to help complete the upgrade.
The addition of load-bearing columns to the safe house before consumed 5 survival points when the materials were complete, and the "labor cost" for upgrading the drains should be similar to it when the materials are complete.
"Confirm the upgrade!" Lu Yan simply chose the upgrade method 1, and as a pleasant reminder sounded, the green light shrouded the drain.
The light dissipated, and all the stones had turned into slates, which were neatly laid out in the drainage channel, and the gaps were also tightly bonded by cement!
A stone drainage channel extends directly from the entrance of the safe house to a depression fifty meters away!
[A complete drainage channel]
[Drainage performance: excellent]
【Impermeability: Excellent】
[Function: In the case of heavy rainfall, it can ensure that there will be no accumulation of water near the safe house and prevent backwatering! 】
[Description: Invincible anti-side leakage, caring, safe and comfortable, dry and not wet every month! 】?
