Cao Xing glanced at the properties of the drawing.

【Magic water storage device drawings】

[Drawing introduction: A water storage device that can automatically purify water, heat and maintain constant temperature can be built indoors]

[Materials required for construction: Small electronic component*1, Iron*30, Copper*20, Mithril*5, Primary element crystal*2]

(Note: After the construction is successful, you need to invest a primary magic crystal, which can provide energy for the water storage device for two months.)

…

After seeing the above introduction, Cao Xing was delighted.

"Isn't this just a water heater?"

"That's great! We don't need to heat water for bathing anymore."

Thinking of this, Cao Xing decided to build one in every resident's house tomorrow.

After a moment.

Liu Muxue had also finished washing up.

She tilted her head and wiped her wet hair, like a fairy emerging from the bath.

After seeing Cao Xing, Liu Muxue said softly: "Ah Xing... the water is ready, I'll go upstairs to warm the bed first, you can come up after you take a shower..."

"good."

Cao Xing nodded in agreement, and then took a nice hot bath.

…

On the second floor of the lord's cabin, the temperature here is also very comfortable.

There are burning stoves on both sides, and heating pipes are constantly delivering heat.

For most of the survivors, it was heaven!

It can be seen from the fact that Qiu Yating asked Cao Xing for warm clothes today that most of the survivors are still in a freezing state.

After all, not everyone can be like Cao Xing, who not only upgraded the bonfire to a furnace, but also built heating pipes.

Even Fang Long, who had made good progress, had only just upgraded his territory bonfire to level 6.

At night, most of the survivors could only huddle around the fire to sleep.

It's nice to have a quilt.

At the same time, Liu Muxue poked half of her head out from under the quilt, then patted the pillow beside her and chuckled, "Axing, the quilt is already warm, come in quickly."

"OK."

Cao Xing took off his coat and got into the warm bed.

The next moment, a pair of slender and warm legs came towards him.

The two looked at each other, and there was some shyness and a hint of expectation on Liu Muxue's beautiful face.

After a while, there was a slight sound from the small wooden bed again, accompanied by the charming voice of the beauty.

In the quilt, Liu Muxue twisted her graceful body, making Cao Xing feel as if he was falling into the clouds.

Until an hour later.

The beauty took a quick breath.

She lay contentedly in Cao Xing's arms...

The two hugged each other quietly, feeling each other's body temperature.

Liu Muxue put her long legs on Cao Xing and rubbed him gently.

The smooth touch keeps caressing.

Compared to Xia Yanni and Sarah, Liu Muxue has the most well-proportioned body, especially her pair of long and tight legs, which can be called a perfect work of art.

Of course, this does not mean that Xia Yanni and Sarah are not as good as Liu Muxue, it can only be said that they each have their own characteristics.

A few minutes later, Liu Muxue raised her head and said, "Ah Xing...my parents sent me a message again today. They wanted me to give him some furs."

"But I didn't give them anything. Instead, I asked them to exchange 2,000 pieces of wood or 1,000 pieces of stone with us."

Cao Xing was amused when he heard this, "Did they give it to you?"

Such a large amount of resources is a considerable sum for the survivors at this stage.

Liu Muxue shook her head: "No, they said they didn't have that much."

"I told them not to spoil their two younger brothers too much and let them go to work too."

Cao Xing nodded. "Sure. If they have collected so many resources, it wouldn't be a big deal to trade them a few wolf skins."

After all, for Cao Xing, this was a good deal.

Liu Muxue nodded her head slightly, and a sly smile suddenly appeared under her beautiful facial features.

"By the way, Xing... have you decided which beauty's room you want to go to tonight?"

When Cao Xing heard this, his eyes widened and he coughed a few times.

"Ahem! What are you talking about, Mu Xue?"

After hearing this, Liu Muxue smiled even more brilliantly.

She didn't seem to care about it, and said softly: "Ah Xing... I can actually see how our subjects feel about you..."

"During the day, Sarah and Renis looked at you with such passion that they almost wanted to eat you up..."

"I also know that everyone in this territory loves you and respects me..."

"So, as a lord, I can't have your love all to myself!"

Liu Muxue clenched her little pink fist and said with a firm look.

Hearing this, Cao Xing became even more embarrassed.

He was about to explain something when he heard a knock on the door.

Boom boom boom!

Cao Xing asked in confusion: "Who?"

After a while, a voice came from outside the door: "I... Sarah... have something to report to the Lord..."

Cao Xing immediately looked at the person beside him awkwardly, and then said, "I'll let her come again tomorrow."

But Liu Muxue covered her face and chuckled, "Go ahead, go ahead, just in case it's something important."

"Remember to come back early~"

Seeing that Cao Xing was still a little embarrassed, Liu Muxue continued, "Don't worry too much, just go."

Cao Xing sighed after hearing this.

Then he got up from the bed, put on his clothes and walked out of the lord's cabin.

When Cao Xing pushed open the door, he saw the beautiful dark elf standing aside with her head lowered.

The two pointed ears stand upright, giving people a delicate feeling.

"Sarah, what's wrong?"

Hearing Cao Xing's voice, Sarah raised her head and then grabbed Cao Xing's wrist without saying a word.

Cao Xing noticed that Sarah's eyes became as hot as last night.

Then, she took Cao Xing all the way to her room.

The door closed with a bang.

"Sarah, what do you want to tell me?"

Cao Xing continued to ask.

Sarah didn't answer. This time, she took the initiative to take off her assassin leather jacket.

In the light of the fire.

In an instant, a body with perfect curves appeared in front of Cao Xing.

Then, in front of Cao Xing, she took the initiative to take off her bra.

Instantly, a pair popped out.

"My Lord... Sarah wants more..."

After hearing this, Cao Xing also understood Sarah's current condition.

Then he nodded and said, "Same as yesterday, Sarah?"

"Um……"

Sarah responded softly, then knelt down in front of Cao Xing.

Ten minutes later, Sarah stood up and wiped the corners of her mouth.

And Cao Xing gently picked her up.

Sarah is about 1.6 meters tall and looks very petite in Cao Xing's arms.

Moreover, she was very light in weight; Cao Xing felt that she weighed less than 90 kilograms.

On the small wooden bed.

Sarah was as enthusiastic as she had been the night before.

This perfect body continued to radiate scorching heat, as if it was about to melt Cao Xing.

"Lord Lord...Lord Lord..."

“Hmm…”

After a long sigh, Sarah fell weakly on Cao Xing.

Cao Xing did not do anything else. He just held Sarah in his arms and gently stroked her smooth back with his right hand.

A few minutes later, Sarah seemed to have recovered some of her strength, and she said softly, "My Lord... you are so amazing. You made me feel something I have never felt before."

At this moment, she no longer looked like the cold and arrogant assassin she was during the day, but appeared extremely gentle.

Cao Xing smiled and said nothing.

And at this moment, Sarah's thin lips suddenly curved up.

"Actually, that woman from Ascalon also wanted to find you..."

"But I wanted to feel the lord's love before her, so I decided to bring you here first..."

Cao Xing was stunned for a moment after hearing this. No wonder Sarah went to knock on his door so early.

At this time, Sarah leaned close to Cao Xing's ear and whispered, "But... you can go find this Ascalon woman later..."

Her pointed ears hit Cao Xing, and Sarah's breath seemed to arouse some psychological feeling.

Cao Xing glanced at her.

However, under Sarah's surprised gaze, he suddenly turned over and pressed Sarah under him.

After her initial panic, Sarah's face turned even redder.

She tilted her head and showed her long elf ears to Cao Xing, looking so shy and lovely.

The sound of breathing could be heard again in the room.

More than an hour passed.

The dark elf beauty trembled in his arms, then tensed her limbs and grasped Cao Xing tightly with her slender arms.

After a while, Sarah gasped and her chest heaved violently, then she collapsed.

Cao Xing also gradually felt exhausted.

Compared to Sarah, who is a third-level leader, his physical fitness as a second-level mage is still a little bit inferior.

Cao Xing wiped the sweat from his forehead.

Sarah had a rosy face and a satisfied smile on her face as she kissed Cao Xing on the chest.

After a few minutes, Sarah stood up from the bed and seemed to be getting dressed.

Cao Xing was stunned, then asked, "Are you going out so late at night?"

Sarah nodded and said, "Yes, Lord, the snowfield is just as dangerous at night. We need someone to guard the territory."

"I'm not too confident about the abilities of the newcomers."

"So we discussed it and decided that I would be responsible for the security of the territory in the first half of the night."

"Rhaenys will be there in the second half of the night, and Assam and Andrew will be there tomorrow."

After hearing this, Cao Xing nodded suddenly.

The three people Sarah mentioned, including herself, were all subjects with a loyalty level of over 100.

Unexpectedly, they would take the initiative to help Cao Xing defend the territory.

Maybe this is the hidden function after loyalty reaches 100.

In front of Cao Xing, Sarah wrapped her plump breasts with a few rounds of white cloth again, and then put on the tight leather jacket again.

She held two shadow blades in her hands.

After putting on the equipment, Sarah seemed to have become a different person, full of sternness and murderousness.

"I'm going out."

After saying that, Sarah disappeared silently.

Cao Xing thought for a moment, stood up and put on his clothes again.

As he passed by Renis's room, Cao Xing touched his waist.

In the end, he still didn't go in.

Then, he quickly went back to his lord's cottage to avoid being intercepted by some woman again!

When Cao Xing returned to the lord's cabin, Liu Muxue was looking at him with her big watery eyes and a playful smile on her lips.

"I'm back, Xing."

Cao Xing nodded, then crawled into Liu Muxue's quilt.

The two fell asleep in each other's arms, leaving everything unsaid...

Late night.

Cao Xing vaguely heard several collision sounds near the territory.

One of the collisions seemed to have occurred near the territory.

Boom!

The violent vibration caused the lord's cabin to shake slightly.

Cao Xing and Liu Muxue opened their eyes together and listened for a moment.

After hearing no other movement, he fell asleep peacefully.

"Go to sleep, Muxue. It should be another ice nest. With our ability to defend our territory, we don't need to worry about it."

Liu Muxue blinked her beautiful eyes and nodded.

The two fell asleep again.

…

However, although Cao Xing's territory could withstand the impact of the Icebrood monster, the territories of other survivors were not so lucky.

That night, many surviving lords were awakened by the shock in the middle of the night.

When they walked out of the lord's cabin on a cold winter night, they immediately saw dozens or even tens of ice nest monsters rushing towards the territory.

In an instant, fear appeared in the eyes of these surviving lords.

“Alert! Alert!”

"An Icebrood monster is coming. Call out all combatants!"

"Damn it!"

Bang! Bang! Bang!

Those icebrood monsters were madly ramming into the buildings in the territory.

The battle started instantly.

This is the first night after the novice protection period ends.

The survivors have not yet adapted to the cruel pace of this world.

Even at night, I couldn't sleep peacefully and someone had to stay on duty.

The Icebrood's attack is as fierce as ever.

Some survivors, together with their subjects, managed to withstand this wave of attacks with great difficulty.

But some of the survivors' territories were swallowed up by ice nest monsters in the middle of the night.

The chat channels that used to be relatively quiet in the middle of the night were also flooded with a large number of messages.

Wang Shuo: "Damn it! These damn ice nest monsters didn't stop in the middle of the night. Damn, I almost got swallowed in my sleep."

Bai Mengxiu: "Are there any brothers near the coordinates 8313, 24521, 52311? Two ice nests appeared outside my territory, and many monsters appeared. I can't stand it any longer. Who can save me?"

Cai You: "This damn world is hard enough during the day, and it's even more troublesome at night. How are we going to mine resources tomorrow?"

The chat channels were filled with complaints.

Not only the chat channel in Area 174 where Cao Xing was, but also the world channel was flooded with all kinds of information.

Lester Grace: "Fuck! I was peeing outside and just as I took out my dick, an ice nest fell in front of me. The good news is that I blocked the attack of the ice nest monster, but the bad news is that I can no longer feel the existence of my dick!"

Sharma-Miya: "What kind of a hell of a world is this? We are here just to suffer. Now the Icebrood has breached my territory and I am about to die. I just don't know if I can be reborn as a Brahmin after I die in this world..."

Hasegawa Issei: "Yoshi! The monsters in one ice nest are enough for me to level up to 8. If I get two more, I can directly level up to 10. My undead minions are really powerful!"

Gao Zhiying: "Brothers, hold on! These ice nests are both dangers and opportunities. They can bring us a lot of experience points. If everyone reaches level 10 soon, it will be easy to break through to level 2!"

Wang Teng: "Hahaha! Damn Ice Nest Monsters, come here! I'm already level 9. If I level up one more level, I can directly break through to level 2, and these Ice Nest Monsters will never be able to do anything to me again!"

…

Everyone reacts differently to a crisis.

Some saw this as an opportunity, while others were panicked.

But no matter what, they can only adapt and seize every minute and every second of development opportunities.

And these have nothing to do with Cao Xing.

Their territory has been built with high walls, arrow towers, and powerful men are on duty 24 hours a day.

The two of them slept quite soundly in the second half of the night.

The next day...

As soon as Cao Xing opened his eyes, a system prompt appeared.

【Attention all survivors: You have passed the first day of the official period. 】

[The frequency of Ice Nests appearing and the level of monsters will gradually increase. ]

[When killing an elite or higher level Ice Nest monster, there is a small chance that a special item will drop: Ice Dragon Horn]

[Weather forecast: Today, there will be a cold wind in the snowstorm area, and the lowest temperature will reach -60℃]

…

Seeing the system prompt, Cao Xing asked in confusion: "What is the Ice Dragon Horn?"

At this time, Liu Muxue also glanced at the chat channel, and said with a worried look in her eyes: "Axing, it seems that many people died last night..."

Cao Xing took a look.

[Current number of people online in District 174: 30412/40173]

A large number of people died during the seven-day protection period for novices, and another group died on the first day of the official period.

Now the population in their area is almost falling below 30,000.

The situation in other districts is estimated to be similar, or even worse.

Cao Xing nodded, "Yes, there is nothing we can do about it. After all, we have no territory to protect us."

"Plus, the level of the Ice Nest monsters is still increasing. The other survivors can only seize every minute and every second of development time to survive the threat of the Ice Nest."

Hearing this, Liu Muxue also clenched her fists.

Of course, Cao Xing's time is not that tight, because his progress is far ahead of other survivors.

After a moment, he said, "Get up, Muxue."

"Yeah." Liu Muxue responded softly.

After a quick wash, the two of them came to the lord's cabin.

Dozens of polar people, the leader Cao Yi, and the tree spirits were all waiting respectfully.

After seeing Cao Xing, everyone bowed.

"My dear Lord, I wish you good health."

"My beautiful lady, may you always look beautiful."

Cao Xing nodded, then looked at the two Centaurs beside him.

"Kandar, Kandar, did an ice nest fall down last night?"

The Centaur stepped forward with its hooves, making a clattering sound.

They nodded at the same time and said, "Dear Lord, as you can see, four ice nests did fall near our territory last night."

"We pulled those newcomers out of their hiding places, and together with the powerful Lady Sarah, we killed all the icebrood monsters outside!"

The two centaurs had smug looks on their faces.

Ellie, Sylvia, and several imperial soldiers all had resentful expressions on their faces.

They were sleeping soundly in the middle of the night, but were awakened by a sudden tremor.

Before they could react, Cantor's loud voice began calling out from outside the door.

Then, they had no choice but to quickly get out of bed and follow Kanter and the others out to fight overnight.

Kantel walked over at this time, took out a pile of ice dragon marks and other materials, and presented them with both hands.

"My Lord, this is what we harvested yesterday. Please take a look."

Cao Xing nodded, then put all the materials into his backpack.

[Obtained: Glacial Fragment *243]

[Obtained: Ice Dragon Mark*497]

[Obtained: Small Chaos Book *5]

[Obtained: Small Spirit Book *3]

[Obtain: Ice Crystal (Green) * 32]

Cao Xing nodded with satisfaction, "Well done, Kandal, Kanter, you have worked hard."

…
