The low-level mechanical core is finally in hand, and the water maker can be made.

This is a gratifying thing for Bai Mu, which means that he has a stable source of water. This way, he can focus on other aspects of the excavation process and does not need to specifically look for water resources.

Click on [Manufacture] to find the low-level water maker.

[Low-level water maker: 4/4 copper, 5/3 iron, 13/1 wood, 1/1 low-level mechanical core] [Manufacturing].

Click [Manufacture]

Bai Mu took out the brand-new water maker, half a meter high, boxy, with a small amount of lines engraved on the surface, and the water maker was gray [start] option on it.

[Start] Below is [Energy to be added], after Bai Mu clicked on, he chose to add 4 wood.

The lines on the surface of the water maker began to flow instantly, and after a while, a drop of water dripped from the conduit and fell into the sink.

The sink is sealed, so there is no fear of water contamination.

Following the tips on the panel, 4 pieces of wood can feed the water maker to work for two hours, producing 500ml of water. If you have enough wood to run 24 hours a day, you can produce a full 6 liters of water!

And you need 48 wood to operate a day, if you need 2 wood to sell 50ml of water, and you get 48 wood, you only need to pay 1200ml of water, and you can get 4800ml more, four times the profit!!

Bai Mu dismantled a bottle of his newly found mineral water and put it on the exchange. 25ml of water is only enough for a normal person, but in the current cave environment, a mouthful of water is also a valuable resource, in addition, there are too many materials you need, if the price is set too high, then you can't trade a sufficient amount of materials, just see if anyone is willing to trade.

[Player: Bai Mu (183cm/69.3kg)

Trade Item: 25ml water*1

Required Item: Wood*1

Number of shelves: 22

Seller's Remarks: None]

After confirming the release, as always, the news of the transaction began to pop, except for the long time spent on the trading machinery core, Bai Mu's other transactions were basically empty.

【Trade 25ml of water to obtain: Wood*1】

【Trade 25ml of water to obtain: Wood*1】

......

Bai Mu took out the wild berries in the inventory, small red fruits, only the size of fingertips. Bai Mu took advantage of the time to observe the operation of the water maker, and ate a few nothing, sweet and sour were delicious, just suitable for relieving greasy after eating barbecue.

The water maker has started to drip steadily.

Without worrying, Bai Mu set the water maker aside, and then began to look at the room.

He wanted to upgrade his home, but the dense night at the door made him feel a little uneasy, and the light of the fire seemed to only illuminate his house, and when the fire reached the door, it seemed to be swallowed by the night. In addition, the map has hinted that cave monsters basically have the ability to dig soil, and the walls of their homes are earthen walls.

Therefore, it is necessary to upgrade the home.

Click [Home] → [Build], since there are no architectural drawings, so you can only upgrade on the original basis.

Currently, there are only two options: Wall and Floor.

[Walls (Upgradeable): Stone 55/30, Earth 389/30, Upgrade]

[Floor (upgradeable): 1. Wood floor: 55/4 stone, 30/15 wood, upgraded; 2. Stone floor: Stone 55/20, upgrade]

Bai Mu directly clicked to upgrade the wall.

After clicking, there was a flash of light in the room, and the whole thing turned into a slightly white stone wall, Bai Mu stepped forward and touched it casually, it felt rough and slightly cool.

It's not bad, the stone wall makes Bai Mu's heart settle down a little.

Flooring, Bai Mu chose to upgrade the stone floor, the reason why he did not choose the wood floor is from the safety considerations, of course, the comfort of the wood floor will be much better, but the wood has stone is more reassuring in this situation.

Now there is no door in the home, which is a big problem and full of hidden dangers.

There is a trap dug at the door, but what if it is a flying monster?

But at present, there is no blueprint for the door, and there is no way to build it, so Bai Mu can only click on [Manufacture] and make three wooden boards, just enough to block the door frame, and then take out the stones from the inventory and overlap them to block the wooden planks.

After completing the whole process, Bai Mu breathed a sigh of relief.

At least for now, ordinary monsters shouldn't be able to get in.

After finishing the matter, Bai Mu sat back next to the fire and checked the exchange, and no one traded the drawings. Bai Mu went to the chat channel again.

At this time, the wind direction of the chat [World] channel still hasn't changed much, and he is still scolding Zhao Ge.

It's just that now, there is also the name of Bai Mu.

"I finally grabbed the water of the white herd boss!"

"Bai Mu's items can only be robbed, unlike a certain pretending criminal, surnamed Zhao Mingge, who relies on strength to trade items."

"The difference between a real boss and a pretending boss. The real boss doesn't say a word, just releases food and water to trade, and pretends to be a big guy who only says that it depends on strength. ”

"Big guy Bai Mu, forever dripping gods!"

But it's also mixed with strange remarks.

"Big guy Bai Mu's barbecue skills need to be improved, wow, the barbecue meat that looks so good is completely ruined!"

Bai Mu really wanted to reply, it was not his poor skills, but the problem of the meat itself.

However, considering that it takes 60 minutes to speak once, forget it.

And when Bai Mu opened the [Region] channel, Bai Mu had a sense of urgency to survive.

"I heard voices outside my home, how are you there? A little scared. ”

"Me too, I always feel like something is watching me."

"I'm so cold."

"There was real movement outside the door, and I felt like I saw a pair of green eyes...... Damn! There really is something! It's coming, save ......."

When he saw this, Bai Mu frowned, because he found the number in the lower right corner of the regional chat, one was missing, and now it was 781, he had seen this number when he came, but he thought it was just the number of chat records, and he didn't care.

At that time, the number seemed to be around 1,000.

780......

Turns out this refers to the number of people in the area!

Bai Mu was a little stunned, was there so many people missing in one day?

Sure enough, his previous anxiety was correct, and in the dark night, there will be many monsters in the cave that will not appear during the day. And countless people have already paid with their lives for it.

It was those numbers that made Bai Mu's mood slightly gloomy.

"Try to upgrade the walls and floors, the door frame can find something to block, the monsters in the cave can dig the soil layer, and the earthen wall that has not been upgraded is not safe."

Bai Mu posted his first sentence in the cave on the [Region] channel.

As soon as he spoke, the chat history quickly increased.

"It turns out that the big guy Bai Mu is in the same area as me."

"What's the deal with a sudden sense of security?"

"Please hug your thighs!"

Bai Mu looked at it for a while and then turned off the panel, he reminded at most that he had no energy left to do more, so he could only say that everyone has their own lives.

When drowsiness hits, Bai Mu adds another 12 wood to the water maker, so that with the previous 4 woods, the water maker can run for 8 hours, and when it dawns tomorrow, you can get almost 2000ml of water.

At that time, you can exchange water for wood and continue to run the water maker.

Bai Mu lay on the snakeskin, using the sheepskin directly as a quilt, and with the fire, he couldn't feel the cold.

After a tiring day, Bai Mu quickly fell asleep.
