Slowly approach the windowsill and touch the liquid ball.

Including digging, looting, trading.

Iron block: 165

Spirit stone: 61

Wood is still the previous 245.

There is still a flint to upgrade the safe house.

The number of times to dig the corner and the shovel is capitalized.

[transaction completion]

[pink stockings: - 1]

[iron block: + 5]

——

Someone really changed it?

Call out the game panel and click on the trading partner information, which is also anonymous.

This man

I guess it's also about face.

Yu Cheng switched to the [chat] column. I haven't seen you for a long time and click to have a private chat.

Choose a female avatar.

(Yu lingxuan, female)

Edit the message and send it.

"Flint, yes?"

Moyo waited a minute or two, but no news came back.

Close the game panel.

It's too extravagant to exchange a few flints with the drawings of low-grade water purification collectors.

Yu Cheng gave up his plan to trade the drawings.

"Master..."

Xiaofen walks to Yu Cheng and looks eager.

??

Seems to be aware of his doubts, Xiaofen pointed to his iron bowl not far away.

Is it necessary to replenish foreign body blood so soon?

Yu Cheng stares at Xiaofen.

The blue screen emerged.

[overwork]

[foreign body blood shall be taken in advance]

——

Indeed, Xiaofen fought a little frequently this day.

Go to the window, call the sleeping screen on one side, and slide the blue screen.

Find out the remaining 600ml serrated snapdragon blood and pour it into the iron bowl and stone bowl of small powder.

"Good master!"

Xiaofen smiled at Yu Cheng, then went to the stone bowl and began to swallow.

[system prompt: unread message waiting to be checked]

It should be the woman.

In order to prevent harassment information, Yu Cheng has already deliberately turned on no disturb. Only after chatting can they send messages to each other, otherwise they will be rejected.

Call out the blue screen and open [chat].

The head of a woman with dark hair kept fanning.

Click on it.

(Yu lingxuan, female):

"Do you have a windstone?"

"Flint, I have one here."

Perfect!

Yu Cheng starts editing the message.

send out.

"Flint already exists."

"There is another wind stone."

The other party obviously paused for a while. It was estimated that he didn't come back until a minute later.

"What else do you want?"

The fish got caught

Edit, send.

"Nothing else."

"Flint with filter or insect repellent."

"So you don't have flint?"

Looking back at the news, Yu Cheng smiled and sent the edited information.

"If you think so, the chat is over."

Exit the chat box.

Change to the [transaction] column.

The next thing to do is to wait

Through previous dealings, it is obvious that the woman is anxious.

Simply flipped the [transaction] page.

In addition to some reliable materials such as wood, iron, dry bread and so on, the rest is a pile of all kinds of things.

[trading item: Fairy stick]

Dry bread × 2】

[trading item: Zishui gun]

[required: iron block × 8】

——

[trade item: human reproduction manual]

[transaction demand: 800ml water]

——

This nm is darker than me!

Yu Cheng continued to decline, looking for useful materials.

At the same time, the [chat] column began to shake.

The woman guessed that she couldn't wait.

Shift your eyes to the dialog box.

indeed.

Yu lingxuan's head is shaking.

Click on it.

(Yu lingxuan, female):

"OK."

"But there is no filter, only insect repellent grass."

Yu Cheng did not respond and began to set up the transaction information to get flint and insect repellent grass.

Then send it.

[system prompt: transaction succeeded]

The flint appeared in Yu Cheng's hand. It was mild and slightly fragrant.

Wait

Yu Cheng turned to the trading office. The previously anonymous information came from the same source as Yu lingxuan at the moment.

what?

What does she want those pink stockings for?

The other party seems to be aware of something and clears all the previous transaction information.

Both of them didn't send out the next message.

Close the game panel and put the flint obtained from the transaction on the windowsill.

Finally, this level of safe house can be transformed into level II.

Yu Cheng looked forward and stared at the rotating spirit liquid ball on the grain.

There is more grill in the first level, and I don't know what will be more in the second level.

Stretch out your right hand and press it down on the spirit liquid ball.

Required for upgrading materials:

Timber: 200 (245)

Iron block: 150 (165)

Flint: 4 (4)

Wind stone: 2 (4)

Spirit stone: 20 (61)

Driving force: 1 (1)

Drive core: 1 (1)

[system prompt: upgrade safe house?]

The [yes] below finally shows a long lost blue light.

Keep your eyes fixed and confirm.

The bracelet disappeared on Yu Cheng's wrist. The golden light immediately wrapped him and Xiaofen's body. Then one person and one dragon were slowly sent outside the safe house.

The little powder claw carried a stone bowl and was still licking it.

The little guy looks really tired.

The golden light completely surrounded the safe house. From time to time, I saw wood and iron flying around. I don't know what to do.

"Eh?"

"Master, why are we here?"

Xiaofen didn't forget to lick a small stone bowl, and his state seemed to return to his best.

Yu Cheng indicated the front safe house.

Touched little pink's head.

"I like my master best!"

Xiaofen rubbed against Yu's trouser legs, and the pink tail kept shaking.

Accustomed to this attractive voice, Yu Cheng looked at the safe house not far away and looked forward to it.

long time.

The golden light dissipated slowly, and the blue screen appeared above the safe house at the same time.

[system prompt: safe house upgrade succeeded]

[safe house level: 2]

——

After two or three seconds, the blue screen dissipated in the cave.

The remaining light of the package safe house slowly dissipated, showing the current upgraded appearance.

Wood blocks spread around it, iron blocks were replaced with iron sheets, and the house was covered all around.

From a distance, it looks like a small silver fortress.

Yu Cheng stepped out and came to the upgraded safe house.

From the outside to the inside, there have not been too many changes except the appearance.

Into the safe house.

The materials inside are placed neatly, and the windowsill still exists in the previous position.

A fresh breeze came slowly, and the grill was upgraded again.

The charcoal inside dissipated and replaced with a red light source.

If you guessed right, you should have used flint.

Except for previous material changes.

There is a small box object in the house, which is located in the middle of the floor.

Keep your eyes on it.

Blue screen display

[system prompt: drive protection?]

Is this the driving core?

Trial use, confirmation.

[yes]

[system prompt: do you want to use ten spirit stones?]

[no]

Want to pit the spirit stone again?

Or waiting for an emergency to drive again, almost hit the jackpot!

Xiaofen went to Yu Cheng and sat in front of him.

In the corner.

The cave clock did not change its position.

Record the time.

4:30 p.m.

It shouldn't be delayed. The caves are completely dark in an hour or two. Who knows what will appear again.

Think of this.

Yu Cheng walked outside the safe house
