This is survival, why don't you put it aside for health preservation?

Li Tian went back to the island monument, took the B-level cassette that was just opened last night on his body, and walked to the pigsty with two buckets of vegetables and a bundle of seawater rice stalks.

In the pigsty, the three-legged confrontation that Li Tian expected did not appear.

Now, the C-grade cow and the B-grade pig are in the same camp, both resisting and despising that ordinary cow.

Seeing the ordinary cow shivering in the corner, Li Tian felt distressed.

"Are you two bullying others?" Li Tian looked at the pig and the cow who were close to each other and asked.

But who would have thought that the two of them raised their heads tacitly at the same time and called out, not to mention pulling too much.

"No, both of you are obviously female, or different species, so why are you so closely related?"

Li Tian was very puzzled, but he couldn't get a response from them.

"Well, don't regret it."

After saying that, Li Tian directly took out the b-level upgrade card and used it on the ordinary cow.

The next moment, the ordinary bull spirit changed.

The horns of the cow are getting sharper and thicker, and the hair is much more beautiful than that of the c-level cow.

Properly handsome cow!

When the cow saw this, her already round eyeballs widened a bit, and she quickly moved away from the wild boar, and looked at the B-rank cow, mooing.

But the b-level cow glanced at it indifferently and ignored it.

This amused Li Tian, ​​it turns out that Niu is also so snobbish.

As for the great white shark cub, after thinking about it, Li Tian decided not to feed it, as he didn't have so many eggs to feed it, so he could only feel wronged for the time being.

After finishing all this work, Li Tian went to cook.

......

After lunch, the three of them walked towards Li Tian's room and looked at the screen of the island monument.

Click [Receive Task]

"Today's task is not difficult." Li Tian accepted the task with a smile.

After Wang Lao heard this, his eyes lit up: "It's not difficult, I can't wait for this task every day! Don't talk about it, I'm going to fetch 20 pieces of black soil and plow the field!"

Looking at Wang Lao's leaving back, Li Tian and Li Erbiao looked at each other, dumbfounded.

As for the task of expanding the area of ​​the island, it is not to mention how simple it is. There is a lot of storage in the temporary pumice storage warehouse, so just use it directly.

"Next, when Mr. Wang has reclaimed the black soil, we can develop supplies. Let's continue to burn charcoal fire first?" Li Tian suggested.

But as soon as the two of them entered the stove and lit the fire, Mr. Wang walked in with a drooping face.

"Old Wang, what's the matter, aren't you feeling well?" Li Tian asked worriedly.

After hearing this, Elder Wang just sighed and didn't say anything.

This made Li Tian and Li Erbiao even more anxious.

"Old Wang, what's wrong with you, don't scare us."

Only then did Mr. Wang smile wryly and said: "Hey, people are old after all, and they can't grab the machine. I just plowed a piece of land, and that little Yi plowed the 19 black soil I just used."

"Don't talk about being addicted, even the itchy hands haven't been cured... hey."

At this time, Mr. Wang was really wronged like a child, but fortunately, there was nothing wrong with him, which also made Li Tian and Li Tian heave a sigh of relief.

However, in order to stabilize Wang Lao's mentality, Li Tian was both a comfort and a reminder.

Said: "Old Wang, don't forget, we have been rewarded with 20 pieces of A-level black soil for completing the mission, you go and take it out, and see if it is worthwhile to plant something."

Sure enough, upon hearing this, Elder Wang was full of enthusiasm: "Okay, I'll go right away!"

......

After the mission was completed, Xiao Ai and Oli quickly salvaged the supplies ashore, and Li Tian and Li Erbiao stopped their work and went to open the supplies box.

[Open the material box and get: b-level waterwheel power generation device*1, which has been stored in the temporary storage warehouse of the island monument. ]

[Open the material box and get: expanded pumice*5, metal*10, which have been stored in the temporary storage warehouse of the island monument. ]

......

051. The sea is frozen, S-level upgrade card

"Water wheel power generation device? This is a good thing." Li Tian smiled, and immediately took it out, and installed it in the freshwater stream that evolved from the island.

The water is flowing, just enough to drive the water wheel to rotate.

The installation of the water wheel power generation device is exactly the same as the previous tap water system, and it will be installed automatically when it is taken out.

It is directly connected to the cable of the main switch of the farmhouse house.

And through the system reading, the waterwheel power generation device can also store electricity for the solar storage panel if it does not use electricity.

This just makes up for the embarrassment of solar energy failure when the weather is bad.

the next afternoon.

Li Tian and Li Erbiao continued to burn charcoal. Among them, Li Tian also contacted the boy by the sea, and learned that everything was fine with him, and he was already on his way to pick up the fifth member.

......

At 12:[-] midnight, everyone ushered in the third day of winter!

The winter is bitter, and a thin layer of ice has appeared on the sea surface. I am afraid that it will not take long for the sea surface to freeze completely, and it will even be possible for people to walk.

This is good news for any survivor, as they can easily walk to the sea to get supplies.

But for Li Tian, ​​this is tantamount to bad news.

Not to mention that this will restrict Xiao Ai and Ollie's fishing supplies, but it will also affect the Tiangong members who are sailing on the sea.

"The big thing is not good." Looking at the snowy world outside the barrier, Li Tian sighed.

Li Erbiao also had a sad expression: "It's only the beginning of the third day, and there are still four more days. I'm afraid the temperature will get lower and lower in the future. I don't know if the guys in Tiangong can bear it."

"Let's keep in touch with them all the time, and then we will sleep in shifts, and we must always meet all the needs of Tiangong members." Li Tian suggested.

Li Erbiao nodded again and again: "Okay."

The good news is that even if the sea is frozen, Xiao Ai can still work normally, but Ollie can't help Xiao Ai.

This result was naturally acceptable to Li Tian, ​​so he didn't complain.

After Xiaoai fished all the material boxes ashore, the two opened the material boxes according to the division of labor.

[Open the material box and get: Ice Chisel Drill*1, which has been stored in the temporary storage warehouse of the island monument. ]

[Open the material box and get: s-level upgrade card, which has been deposited in...]

......

"Goddess of Luck has opened her eyes." Li Tian couldn't help laughing when he saw such treasures unpacked from the supplies box.

But the use of the next s-level upgrade card stumped Li Tian and Li Erbiao.

Naturally, this kind of thing cannot be used casually, after all, it is too rare.

Li Tian has developed so far, and there are not many S-level things on the entire island.

Only reasonable upgrades can make it play its biggest role.

The first thing Li Tian ruled out was poultry and livestock. B-level cards are fine for them, but S-level cards are really wasteful.

As for the two power generation devices, the current electricity generated can also be supplied normally, and it is not necessary to upgrade.

As for those crops, there are now 20 pieces of A-grade black soil, and they are cultivated with A-grade black soil, and soon they will not lack A-grade crops.

After eliminating layer by layer, the final remaining options are nothing more than water resources and one's own quality.

Li Erbiao suggested that Li Tian should upgrade his quality to S level in order to deal with some dangerous situations.

But Li Tian rejected it.

Their bodies are now at the b+ level, but they didn't use the upgrade card during the period.

So this means that eating those foods with levels can also increase your own level.

That being the case, why not use the s-level upgrade card to upgrade the large distillation device?

In this way, everyone on the island can rely on s-grade water to improve their physical fitness, which is undoubtedly the best choice.

After telling Li Erbiao his idea, Li Erbiao naturally agreed.

The next moment, a brand-new S-class large-scale distillation device with many high-tech elements appeared in front of the two of them.

(S-class large-scale distillation device: 12l of S-class pure water can be distilled every 10 hours!)

Unexpectedly, the amount of water that can be distilled per day has doubled, which surprised Li Tian.

20l of s-grade water a day is completely enough to supply their consumption!

Next.

They just need to wait for the s-grade water to be distilled out.

Go back inside the house.

Considering that Li Erbiao didn't have a good rest yesterday, Li Tian asked Li Erbiao to go to bed.

Tonight he can just watch, Li Erbiao is not pretentious, nodded and left.

With nothing to do, Li Tian continued to go to the kitchen to burn charcoal...

The night was quiet and peaceful, and nothing unexpected happened.

Even the pirates who were extremely rampant some time ago fell silent after winter came.

Maybe they were frozen to death, maybe they were just too cold to move.

But in any case, Li Tian will not let down his vigilance. In today's world, everyone is a dangerous creature.

After hearing the crowing of the cock, Li Tian stopped the work of burning charcoal and got ready for breakfast.

Because it seems that Wang Lao and Li Erbiao will wake up after the cock crows almost every day.Biquge

After the three of them had breakfast, Li Tian was not in a hurry to fall asleep.

He was looking forward to how he would feel after drinking s-grade water all night.

Now, after a night of distillation, there is already a lot of S-grade water in the tank in the water storage area.

Li Tian was not stingy, and took out all of them, and evenly distributed them to Wang Lao and Li Erbiao.

The three clinked glasses and drank together.

Immediately, I felt that my body was changing, and it became stronger and stronger, and at the same time, my vision response was significantly improved!

"Is this the power of S-level water?" Li Erbiao clenched his fists and tried his strength. It was so different from B-level water!

Li Tian smiled and said: "We are only at A-level now, and if we want to reach S-level, I am afraid we will have to drink for a long time."

"Huh? This is only A-level? How strong will the S-level physical fitness be!" Li Erbiao was very excited after hearing this.

"The answer, won't it be revealed by then? That's fine, I'll take a nap for a while, and I'll continue my shift at night!"

......

Emperor Yan's island.

At this time, the scale of his island had reached more than 1200 square meters, but the house he lived in was only a stone house.

The advantage of the stone house is that it is ventilated in summer, and there is no need to worry about burning charcoal. The disadvantage is that it is too ventilated, and when the cold wind hits, he is shivering wrapped in a quilt.
