National Survival: My Ability Is To Sign In

In the bronze treasure chest, Chen Yuan got a water element crystal, a soul, and... 10 crystal fragments.

"Crystal shard?"

Chen Yuan frowned.

On the Mushan Lake side, the werewolf statue is broken, the werewolf fighting skills obtained are incomplete, and even the crystals are just fragments.

What a headache.

"I hope it will be of some use in the future..."

Chen Yuan disassembled the long-tailed crocodile king again.

Get +30 crocodile meat, +1 crocodile armor, and keep the sharpest teeth of the crocodile.

Then, pack up and go back with Xiaobai.

Wait and go back.

The clay transaction was completed. Someone exchanged 10 units of fine-grade clay for 1000ml of Liangbaikai with Chen Yuan.

"Brother Chen, why do you need clay?"

"Strengthening the smelting furnace."

"Smelting furnace? What the hell?"

The other side was confused: "Brother Chen, can you tell me what level your cabin is at?"

"On the way to 4."

There was silence there.

No one in the world has completed Level 3, and even 95% of people have not even reached Level 2 cabins.

Boss Chen is already charging for 4.

horrible!

There are a lot of materials needed to upgrade the cabin because he has the top 100 friends in the world.

Some materials are extremely difficult to obtain.

"Boss Chen, can I exchange your healing medicine for something else?"

The man asked again.

"Healing medicine?"

Chen Yuan was stunned and suddenly understood: "Is this why you're here?"

"hey-hey."

There was a smile on the other side: "Yes, Mr. Chen, my friend is injured and needs this urgently."

Chen Yuan noted that healing medicine can generally heal trauma in half a day. Since it can be released, the game has obviously been verified and certified.

"what do you have?"

There was a lot of talk over there.

Chen Yuan shook his head: "These cannot be exchanged for an excellent healing potion. I can exchange it for 30 units of excellent sand and soil on the market. I will not exchange anything else unless I recognize the value."

"Okay, don't be angry, Mr. Chen, I'll go ask."

Maybe he asked his friends over there.

Chen Yuan didn't care either.

After Chen Yuan strengthened all the clay and put it on the smelting furnace, and the smelting furnace completed the last step, the man sent another message: "Boss Chen, can I exchange it with you for a drawing of an excellent gas mask?"

Excellent grade gas mask blueprint?

The level is okay.

and.

Things like blueprints are currently the rarest materials, and their value is not inferior to elemental crystals.

After learning, if you make batches, the value will be even higher.

Even if you don’t use it now, you can in the future.

"Okay, you place a deal."

"Okay, thank you, Mr. Chen."

One minute later.

[Game Tips: Excellent Grade Healing Potion -1]

[Game tip: Excellent gas mask production drawings +1]

Chen Yuan took it out and studied directly.

[Game Tips: Successfully learned the blueprints for making excellent gas masks! 】

[Excellent gas mask: one of the daily devices, capable of preventing most poisonous gases and purifying the air. The size can be customized. Materials required: 32/4 iron block, 9/2 silver, 2/1 rubber, 10/1 crystal fragments , is it produced? 】

All required materials are available.

The rubber is the material that fell out of a Gray Wolf iron box.

What surprised Chen Yuan even more was that the crystal fragments could be used to make gas masks.

"Is it made?"

The game sent another prompt.

Chen Yuan shook his head.

Not necessary yet.

It’s not too late to make it when needed.

Next, Chen Yuan prepared lunch, which was the freshest grilled steak, a skill in the "God of Cooking Book".

Five or six kinds of seasonings were used.

It tastes amazing.

Chen Yuan couldn't wait to post a video and send it to the world channel.

pity……

"This poor channel doesn't have this function..."

period.

Chen Yuan looked at the sand trade again. There were people trading fine-grade sand one after another, but there were no large quantities.

"Forget it, let's go to the wasteland to see..."

After eating, Chen Yuan took Xiaobai and set off.

I thought about it yesterday.

In the morning, we visited the lake and got rid of the Beast Queen there. In the afternoon, we went to explore the wilderness.

Over there in the wasteland.

I always feel that it is not simple, and there may be surprises.

Less than ten minutes.

Chen Yuan took Xiaobai to the edge of the wasteland.

At the beginning, Chen Yuan did not step into the past, but now he is about to set off.

Xiaobai was originally behind Chen Yuan.

When he arrived at the wasteland, he sniffed and stood in front of Chen Yuan.

"You want to clear the way?"

"Hmm..."

Xiaobai nodded repeatedly. Xiaobai's ears were very sensitive and his sense of smell was also very good. The grass was up to his knees.

It's safer to have it leading the way.

"Okay, then be careful."

Xiaobai then ran out, not very fast.

Chen Yuan followed closely behind.

If Xiaobai hadn't been Chen Yuan's pet beast, Chen Yuan could sense his position and it would have been easy to lose him in the grass.

Because the height of the grass is not low, the line of sight is also affected.

At this time.

There was a stir in the grass, and the next moment, Xiaobai appeared in front of Chen Yuan with a small khaki snake in his mouth.

[Soil Snake: A kind of snake in the Forgotten Wasteland, level 12, slightly poisonous, often found in the sand]

Forgotten wasteland?

Often haunt the sand?

The level 12 Earth Rock Snake is simply too weak for the level 16 Xiao Bai who has the bloodline of Queen Rabbit.

Then.

Xiaobai seemed to have released its breath.

Susu~~

There was a rustling sound in the grass dozens of meters ahead, as if countless earth and rock snakes were fleeing.

Xiaobai still has this function?

good.

Fortunately I didn't stew it in the first place.

Keep going.

Because there were too many weeds, Chen Yuan wanted to take out the mist-repelling stones and try them on the map, but there were only two of them, so he gave up in the end.

At this time.

The front suddenly became clear.

A small pond appeared in front of me, and there were a lot of sandy-yellow soil particles on the edge of the pond.

[Game tip: I found fine-grade sand, do you want to collect it? 】

Chen Yuan's eyes suddenly lit up.

There is actually fine-grade sand here, so much of it?

This forgotten wasteland seems to be full of treasures.

In front of the sand, countless small snakes were swaying in the pond. They were the rock snakes that had escaped in the grass before. They ran here.

"Xiao Bai, I give you a task!"

"Watch them."

Chen Yuan ordered.

Xiao Bai immediately jumped up and stood by the pond with grinning teeth, glaring at the group of rock snakes hanging in the water.

After being frightened, most of the earth-rock snakes ran away.

"good."

Chen Yuan took out the shovel.

Dig in this sandy soil.

[Game tip: Excellent grade sand +2]

…

During this period, Chen Yuan canceled all sand and soil transactions in the trading channel.

Why trade when there is so much sand?

Then, more than half an hour later.

A big pit was dug by Chen Yuan on the edge of the entire pond.

All the fine-grade sand and soil were hollowed out by him.

In addition to the 120 units needed to meet the needs of high-quality concrete, there are also 80 units of fine-grade sand and soil collected by Chen Yuan, plus an additional 32 units of fine-grade sand and soil before the transaction was cancelled.

There are now 232 portions of fine-grade sand.

The fine-grade stone also reached 125 copies.

Moreover, there is water here.

then.

Chen Yuan took action again, dug the pit much larger, poured 120 units of fine-grade rocks and sand, and introduced water into the large pit.

Stir.

Keep stirring.

Half an hour later, the high-quality concrete was finally made, and Chen Yuan put them all into the warehouse.

At this time, a melodious flute sound came.

Chen Yuan jumped out of the pit and stared at the past.

I saw a skeleton man playing a flute and with an iron ax on his waist, appearing on the other side of the pond.

"Chacha..."

It grinned at Chen Yuan, and then, with his knuckles clenched tightly, he took out the battle ax from his waist.
