Room survival: I know the prompts behind the door in advance

Chapter 64: Open the box and upgrade the room
Seeing this, Lin Qing's eyes lit up and she exclaimed: "What a good thing!"

No wonder 404 dared to chat with her outside for so long just now. It turned out to be because of these props.

In addition to these three props, there are some pieces of animal meat in his space backpack, as well as some drinking water and food.

The room upgrade materials dropped include 80 planks, 22 bronze ingots, 66 nails, 140 stone blocks, 10 black crystals, and 3 world gold coins.
He didn't know where he collected so much, but Lin Qing still happily accepted it.

After all, it was also her gain.

By the way, she worked hard and opened the 5 wooden treasure chests, 1 bronze treasure chest, and 1 black stone treasure chest that she harvested on the way.

Among the 5 wooden treasure boxes, there is an empty box, and the remaining items are 2 bottles of mineral water, 3 bags of bread, and disinfectant alcohol.

A total of 10 planks are broken down.

From the bronze treasure chest, an iron sword came out.

But it's just a simple item, not a prop. Like her stainless steel saber, it's a cold weapon.

This was of little use to her. After all, she was used to using stainless steel sabers and was not used to using other weapons.

As for the last black stone treasure chest, Lin Qing was still looking forward to it, hoping to find a useful item.

After opening it, what I saw was equipment supplies.

There is a box full of supplementary magazines for the frozen shooter, as well as the AK47 automatic rifle and its matching spare magazines.

Lin Qing's eyes lit up, he raised his hand to fish out the AK, and pulled the bolt, "Wow, cool!"

This shiny smooth bore and heavy mechanical feel seem to be full of strength!
There was also a set of black tactical clothing inside, which seemed to fit Lin Qing's physique just right.

"Not bad. You can wear it if you encounter a dangerous world."

Lin Qing muttered to himself, took out the contents, disassembled the black stone treasure box, and obtained 6 black crystals.

This time, during the trip to the dollhouse, a total of 15 wooden treasure chests, 2 bronze treasure chests, 3 black stone treasure chests, 33 world gold coins and 1 world silver coin were harvested.

The materials that can be broken down are 30 wooden boards, 4 bronze ingots, and 18 black crystals.

There are also some materials found in several other wooden treasure chests, plus the proceeds from the seizure of 404, a total of 144 wooden boards, 26 bronze ingots, 70 nails, 150 stones, and 20 black crystals.

It looks like the harvest is pretty good.

Lin Qing had a lot of materials left after upgrading the fourth-level room, and there was still a lot left in total.

I wonder if I can upgrade to a fifth-level room.

While thinking this, she opened her personal panel again and checked the materials needed for upgrade.

【五级房间升级条件：木板375/160，青铜锭70/48，钉子103/160，石头150/200，黑晶60/60，紫铜55/10.】

Unexpectedly, this time the nails and stones were not enough.

Lin Qing's heart suddenly tightened and she felt a strong sense of crisis.

The materials for upgrading these rooms have actually doubled. It seems that the next time the rooms are upgraded to level 6, they will be doubled again on this basis.

Unexpectedly, I was stumped by these simple materials.

Just now, I pretended to be cool with 404, but I gave her another boomerang invisibly.

What a miserable word.

In the zombie world, she and A013 chopped some wood, which could be processed into wood using the workbench.

But what she lacks now is not wood.

"I hope I can go to a world with abundant resources. Upgrading this material is too uncomfortable."

Lin Qing sighed speechlessly.

She had to make the pickaxe quickly. Maybe a resource world would be opened sometime, allowing her to upgrade while lying down.

Thinking like this, she almost couldn't restrain her impulse and wanted to try her luck outside the door. Maybe she wouldn't be tricked and could pick up some boxes.

However, Lin Qing quickly gave up this idea.

It's not worth it to upgrade the room. After all, the purpose of upgrading the room is to better protect yourself.

Otherwise, it would be too much of a loss.

At this time, Lin Qing suddenly thought that she seemed to have sold some of the cigarettes and alcoholic beverages that she had listed in her personal mall some time ago. She wondered if these would be enough.

With this in mind, Lin Qing opened his personal mall, and the goods listed above were indeed sold out.

The balance in the personal mall shows that there are some materials accumulated and can be withdrawn.

There are 240 planks, 28 bronze ingots, 200 stones and 100 nails.

"Wow, I didn't expect it to be so profitable selling things!"

Lin Qing sighed in shock.

These upgrade materials are enough.

Lin Qing extracted the materials from the personal mall. At this time, the room upgrade system on the personal panel showed that it could be upgraded.

Lin Qing decisively agreed, "Upgrade!"

This time, a burst of soft white light still appeared on the walls of the room, and it seemed that it was being upgraded and renovated.

Lin Qing had experience this time, slowly eating oden, drinking sparkling water, and waiting for the room upgrade to be completed for a longer period of time.

She also took the opportunity to go upstairs and pour the obtained plant growth liquid on the plants on the three plots of land, hoping that this would speed up their growth and allow her to eat fresh vegetables as soon as possible.

Lin Qing also specially collected the grape seeds left over from eating grapes and planted them in the soil in an attempt to harvest some fruits.

"I don't know if this will work. I hope it can grow into a grape plant so that I can eat grapes as soon as possible!"

Finally, Lin Qing poured enough water on the fruits and vegetables, hoping that they would grow up as quickly as possible.

Soon, the room upgrade was completed with a shudder, and the white light dissipated.

This time, Lin Qing's room was much more refined. Not only did the room have warm wallpaper, the solid wood floor became smoother and more precious, and even the bathroom had a completely new look.

What's more important is that there is an extra fireplace on one wall of this room that can burn wood for heating.

It looks like there are special vents outside.

Of course, Lin Qing didn't need to climb up to see it. It was definitely like the socket without wires. There was no ventilation opening and it disappeared naturally.

Just for decoration.

At this time, Lin Qing noticed that there was a screen-like device beside the door of the originally plain room.

She checked it out curiously, but to her surprise, it was actually a device for setting up a defense system outside the door.

"Damn it! You can actually install a room's defense system. This function is great!"

Lin Qing exclaimed.

She swiped the screen next to the door and saw that the existing devices included only some simple expulsion weapons.

But it was enough for her needs.

Greatly improved her sense of security!

"It's simply great! It seems that as the room level increases in the future, this defense system will also be upgraded accordingly."

Lin Qing realized this phenomenon and understood the importance of upgrading the room.

If you encounter a dangerous world, wouldn't it be possible to resist the danger without going out?

　Thank you for your support. I have good news for you all. The PK retest has been completed! So there are recommendations later. The author’s book will not die for the time being (breathe a sigh of relief)

　　Seeing that You Baozi has always wanted to add more updates, but the author's coding ability is limited, and some plots and settings need to be pondered, so two updates a day is more suitable for the author. If he can code more, the author will also Will update from time to time

　　Lulu also listed a lot of interesting imaginary worlds. Now that I have the opportunity, I will work hard to write good stories to repay everyone. Take a bow~
