MTL - Armageddon: Shelters Can Be Upgraded Infinitely-Chapter 30 The heavy rain is coming, the last sweep

If you want to be an arms dealer in the wilderness, you must ensure that you have the strength to suppress those ghosts and monsters who have weapons.

Lu Yan knew this very well.

Before he has the ability to manufacture lv2 weapon products, he will not easily sell cold weapons such as bows and arrows, spears, etc. among the lv1 weapon products.

He opened the weapon manufacturing page. So far, Lu Yan's weapon manufacturing proficiency is lv1 (7/30), and there is still a gap of 23 proficiency points before upgrading to lv2. It is probably enough to make 8 more sophisticated weapons to meet the upgrade. condition.

"There is no problem in making lv1 sophisticated weapons, but lv2 weapon products are similar to flintlock guns, bird guns, etc. Compared with lv1 weapons, the materials required to manufacture them are much more, and the quality requirements are also much better. A barrel needs to be customized with extremely high-strength steel..."

"There are also materials for making black powder, and flint for igniting gunpowder... These things are rarely seen in the trading field at present."

"If I upgrade to lv2 weapon crafting proficiency now, I may face the dilemma that although I have the ability to craft advanced weapons, I don't have the materials!"

Lu Yan analyzed his current situation very accurately.

The current him is not suitable for consuming precious survival points and steel, wood, etc. to upgrade the proficiency of weapon making. He can save these things temporarily and use them in other more urgent places, and wait until enough materials are collected. Consider this.

[Sell item information: 5000ml mineral water]

[Necessary items: copper ore with a copper content of more than 20%, iron ore with an iron content of more than 50%, pure copper, pure iron, various steel materials, gunpowder, raw materials for making gunpowder, kerosene...]

[Exchange ratio: copper ore 1 unit: 10ml! Iron ore 1 unit: 5ml! Pure copper 1 unit: 50ml! 1 unit of pure iron: 10ml...]

Of the remaining 7 liters of drinking water, Lu Yan kept 2 liters for his own use, and put the rest on the shelves.

Although some other materials are added to the required items, the main target of Lu Yan's transaction this time is all kinds of ores, which are of high quality and low price, although all players are well aware that after the early stage, the value of metal ores will be greatly reduced. There were gains, but they had to face an important problem.

That is, if these things are not sold, it will be difficult for them to survive the early stage! Even if they survived, most players do not have the technology and equipment to smelt ore!

In a short time, the significance of keeping these ores in their hands will not be too great!

"Damn it! Lu Yan is a bastard, I said he has a lot of water reserves in his hands, as expected! I want to share!"

"Buy a lot of ore... Could it be said that Lushen has the technology to refine metal?"

"This is so frightening! We are still gnawing bark to catch bugs, and Lushen has already started to move towards the industrial stage!"

"Hahaha, my safe house is close to the mine. A lot of ore has been mined in the past few days. The 5000ml of mineral water is mine!"

It didn't take long for Lu Yan's drinking water to be hung up, when the success of the transaction sounded one after another.

Instead of staring at the transaction information, he reached out and pushed open the door of the safe house and walked out.

At this time, it was already two o'clock in the afternoon.

At this supposedly hottest moment of the day, Lu Yan felt something strange.

The temperature in the air is still very high, but the sun is not so dazzling, as if covered with a shield, and after standing in the field for a while, the skin and lips do not feel stinging and chapped as quickly as yesterday.

Lu Yan touched his back, and the shirt was soaked through in just three minutes.

But he is very clear that it is not pure sweat that wets his shirt, because if the body loses such a huge amount of water, it will react with dizziness and throat thirst in a short time. discomfort.

He looked into the distance, and saw a group of birds hovering in the low sky, hunting tiny mosquitoes.

"I didn't expect...the rain came so fast!" Lu Yan squinted his eyes and sighed.

Hot temperatures, dark sun, wet shirts, heavy breathing, low birds...

All these signs prove that the environment in the wilderness has undergone drastic changes, the moisture in the air has increased, the high temperature and drought for nearly three days are about to recede, and a heavy rain is about to come!

He looked at the item information in his trading floor, and within a few minutes, the 5000ml of drinking water was completely sold out.

"It seems that among this group of players, many of them don't even have the ability to judge the astronomical environment... Of course, it is not ruled out that this environmental change is regional. It may rain in the area where I am. Others The area is still sunny and poisonous!" Lu Yan rubbed his chin, although he couldn't judge whether the heavy rain was widespread or comprehensive, but one fact is certain, that is, after the heavy rain, the value of drinking water will be reduced. plummeted.

Fortunately, before the heavy rain came, Lu Yan had successfully cashed out at the highest point.

He opened the trading field and found that there were 180 units of copper ore and 420 units of iron ore in his [extractable] item. In addition, there were 20 units of carbon steel, 10 units of iron, and 3 units of soil. Nitrate, 1 unit of sulfur, 1 unit of kerosene!

Lu Yan made a rough calculation, and he could eventually obtain 36 units of pure copper and 210 units of iron by smelting these ores. These things can be used to create more than 200 cold weapons between ordinary and refined grades, excluding the consumption of survival points , Enough to make a fortune for yourself!

"Let's go, let's go! After this heavy rain, a top arms dealer will be born!" Lu Yan showed a bright smile on his face.

The richness of these harvests was far beyond his imagination. In addition to steel ore, he also acquired some basic materials for making gunpowder. With these, the plan to make LV2 weapons is just around the corner!

Taking advantage of his spare time, Lu Yan continued to pick up leaks in the trading field.

Suddenly, his gaze stopped, and a look of astonishment appeared on his face.

He found an extremely rare commodity that looked like an AA battery but had a completely different name.

【Product: Mobile Power】

【Capacity: 3000mAh】

[Place of Production: Ruins of the Secret Realm]

[Explanation: Disposable consumables can be used for mechanical drive and electronic product charging, and the mobile power will disappear after use]

[Required items: weapons, food, drinking water]

What is this, a disposable power bank?

Lu Yan felt thirsty. The [monitoring walkie-talkie] he obtained from the ruins of Baixiong City is currently in a shutdown state due to power loss. This mobile power appears so timely!

Thinking of this, Lu Yan immediately contacted the other party.

[Lu Yan: Hello, how do you sell mobile power? 】

Soon, the other party's reply arrived.

[Qin Yaoyao: 10kg of meat or 1 liter of drinking water, as for weapons...I need to identify the quality first, don't take out the **** stone axes like homemade ones]

The asking price of the other party is very straightforward. Lu Yan thinks for a moment, he will definitely not trade the remaining 2 liters of drinking water now, and the asking price for meat is also a bit high. After thinking about it, he can only use weapons to fight the other party Choose to complete the transaction.

After opening the [Manufacturing] system, Lu Yan used 2 units of wood and 1 unit of iron to rub out a spear.

【Spear (Normal)】

[Total length: 205 cm! Blade length: 40 cm! 】

【Toughness: Medium】

[Strike force: can be charged to pierce the flesh of wild boars, brown bears and other large creatures]

[Explanation: I still can't accept the fact that I am an ordinary spear. I often dream of being held in the hand of a magnificent giant, listening to his chanting: Red Spear, Immortal Shield, Slash Immortal king...]

Soon, Lu Yan sent the spear information to the other party.

[Qin Yaoyao: It has similar attributes to the weapon I destroyed in the ruins, its lethality is not bad, and it can be traded! 】

[Lu Yan: By the way, do you still have such mobile power in your hand? I want to buy a few more and prepare them]

The ghost knows how much power the monitoring walkie-talkie consumes, and how long a mobile battery can support it. Under unknown circumstances, it is always harmless to prepare a few more.

【Qin Yaoyao: To tell you the truth, the output of this item is limited. Even I can only produce one within 48 hours. If it wasn’t for the heavy losses in the ruins, I wouldn’t trade it! 】

Qin Yaoyao's words immediately aroused Lu Yan's association. He speculated that the other party might have obtained a small device that can produce this kind of mobile power in the ruins~www.novelbuddy.com~ and every time it is produced, It is about to enter the 48-hour cooling time!

Thinking of this, Lu Yan could only temporarily give up his idea of ​​hoarding goods.

[Lu Yan: By the way, is there a difference between high and low voltage for this thing? Some low-power electronic devices can't withstand high voltage, and I don't see any specific data on it...how can I tell? 】

【Qin Yaoyao: Hehe, you are asking the right person if you ask me about this! My former teacher was an electrical engineer. I have studied electricity with him for seven years, and I have already mastered electricity! It is no exaggeration to say that if I want to know the voltage of something, I reach out and touch it... and I know everything! 】

【Qin Yaoyao: It's crispy and numb to the touch, it's 220v! There is a bang when you touch it, it is 380v! If it crackles before touching it, it is high voltage electricity! 】

Lu Yan's expression was stiff.

You are really a **** genius!

Judging the voltage by hand... The electrical engineer who taught you this trick must have been "straight" in this life, right?

Lu Yan held back for a long time, not knowing whether the other party was really stupid or deliberately teasing himself, and finally replied politely: 【You...know quite a lot! 】

【Qin Yaoyao: A joke! I knew everything when I was twelve or thirteen years old! Not only academic issues, physiological knowledge is also clear! 】

[Qin Yaoyao: One day just after class, my lower body suddenly started to bleed, and my classmates were terrified, but I didn’t panic at all. I spent a long time explaining to them what menstrual period is, and I also popularized science on the spot, my classmates They all suddenly realized that they adored me very much! 】

【Qin Yaoyao: If the teacher hadn’t yelled like crazy that boys don’t have menstrual periods, and forced me to the infirmary, I might have died in the classroom that day...】?
