Su Heng believes that there are only two possibilities for the existence of copies.

One possibility is that there is no opening on purpose, it is the hidden mechanism of the doomsday world, as if there is a feeling of unwritten rules everywhere.

Another possibility is that the system has not had time to open the dungeon, and it has already been encountered by some lucky players and cleared.

Su Heng’s frame caught fire. While cooking, he paid attention to the information on the exchange.

"Eat something light in the morning."

The iron pan was hot, and Su Heng put the quick-frozen noodles in it.

Looking at the white dough turning yellow and scorching, the fragrance has overflowed from the pot.

After frying both sides, Su Heng presented the dough cake, put a little bit of cold eating rabbit, and made a finger cake.

took a light bite.

Crunchy and crunchy on the outside, the hot noodles are extremely delicate in texture. With a little bit of cold rabbit, it is a perfect meal in the apocalypse!

"It would be even better if there were some bean skins and lettuce!"

Su Heng ate the pancake in a few bites.

"Gu dong gu dong."

After having breakfast, the chill of the morning was expelled by the heat brought by the hot hand-grabbing cake.

Su Heng still did not wait for the transaction information of explosion-proof glass.

"It looks like it won't be available for a while."

Su Heng took the next step, screened the keywords, and found that there is still some information on tempered glass.

"Explosion-proof glass can't be bought, but tempered glass can still be bought."

Su Heng briefly looked around.

"These people really dare to speak!"

For a piece of tempered glass, the highest price was 2L of pure water.

What kind of lion is this to open such a big mouth!

Sure enough, someone commented below:

"Want 2L of pure water? Why don't you grab it?"

"That's right, keep the heirloom for yourself!"

Su Heng then swiped down and saw a seller with a reasonable price.

【Seller: Gu Hongcai】

[Items on the shelf: 1 piece of tempered glass]

【Trade Intention: 400ml Purified Water】

[Remarks: If you want to change some pure water from the treasure chest, get away from the liar! 】

Click on his avatar to chat privately, and after some bargaining, he successfully used 300ml of pure water to get the tempered glass.

[Strengthened tempered glass]

[Quality: Top class]

[Grade: Normal]

[Evaluation: Tempered glass that AK can't break through, an essential material for upgrading doors and windows! ]

The most advanced material?

Su Heng originally wanted to use a piece of tempered glass to make up the count, but he never thought that it was a piece of top-grade tempered glass.

The materials are collected.

The next step is to completely upgrade the safe house.

[Wooden Safe House] has been upgraded to [Stone Safe House]

[Required material: 240/240 stone]

In the safe house model, Su Heng selects the preset customization column, chooses to keep the window of 1m*2m, and adds the tempered glass easily.

Confirm the upgrade!

The whole room has been scanned by the orange code, and the place has changed dramatically!

The original wood disappeared, replaced by stone materials, and even the load-bearing structure of the house was completely changed!

The sun shines in through the explosion-proof glass above his head. Su Heng, who has not seen the sun all night, is stabbed by the light and subconsciously stretches out his hand to block it.

After a few seconds, Su Heng got used to the light.

Carefully observe the tempered glass overhead, which can be used for both lighting and skylights for ventilation.

Even the wooden door of the safe house has been upgraded to a stone door.

After a brief moment, it was about ten centimeters thick, absolutely safe.

【Su Heng's underground safe house】

Space: 75㎡

Structural strength: 95%

Completeness: 99%

Facilities: wooden table, wooden chair, wooden bed, wardrobe

Disaster Resilience: Good+

After upgrading to a stone safe house, the structural strength and integrity have been improved.

Due to the particularity of the stone materials, the overall height and area of ​​the Suheng Safe House have been reduced to a certain extent.

However, only a reduction of 5m2 has no significant impact.

It solved several major problems of moisture-proof, drainage, ventilation, lighting, and earthquake resistance at one time.

【mission completed! 】

[Congratulations for getting: Doomsday Honor 100 points, Doomsday Observer! 】

[Congratulations on getting a chance to draw a lottery, do you want to start the lottery? 】

Good guy.

Su Heng didn't know how likely he was to win the lottery and treasure chests. This was already his third mission, and the lottery was long overdue.

"smoke!"

[The lottery is being drawn, please wait...]

[Congratulations on getting: Chain Armor! 】

As the mechanical female voice in his ears disappeared, Su Heng began to take stock of the rewards brought by the completion of this mission.

The first is the Doomsday Observatory.

[Doomsday Observer]

[Quality: Lower Level]

[Grade: Normal]

[Function: Through the Doomsday Observer, you can check the disaster category 96 hours before the disaster strikes]

[Evaluation: Live well, the apocalyptic wasteland needs the great you to rebuild! ]

"Can you check the disaster category 96 hours before the disaster strikes?"

"The public system is a 72-hour reminder of disasters, which means that I can use this instrument to know what the next disaster will be 24 hours in advance."

An orange-yellow tripod supports the Doomsday Observatory, which can be seen just by leaning down slightly.

"The shape is very similar to the level that often appears on construction sites, construction roads, and bridges."

It is the thing that many people regard as a telescope.

The way to use it is that it must be outdoors. Su Heng happily put away the tripod, hugged it, and walked outside.

The stone door was a little heavy, and Su Heng struggled to push it open.

Choose a stable ground, set up the Doomsday Observer, and start trying to observe.

Through the Doomsday Observer, what Su Heng saw was completely different from what he saw in reality.

The soil, grass, flowers and trees are all covered with white snowflakes.

The goose feather snow fell from the sky, and a thick layer of snow accumulated on the ground.

In addition, on the snow-covered ground, there are different shades left, UU reading www. uukanshu. com Monster footprints of various sizes!

Just looking at this scene, Su Heng's hair stood on end, and he got goosebumps all over his body.

A text message slowly unfolded in the foreground of the doomsday scene.

[Disaster: Storm Calamity Snow]

[Level: 2]

[Disaster Countdown: 92:48:56]

[Reminder 1: Storm disaster snow will last for 72 hours! ]

[Reminder 2: After taking/drinking Xianxue, there is a 50% chance of being infected with an unknown virus, and a 50% chance of death immediately! ]

The latter was killed immediately, the former was worse than death!

After 92 hours and 48 minutes, the storm and snow is coming!

"Looks like this is no ordinary snow!"

"I'm not talking nonsense, otherwise, why would it be called Storm Calamity Snow instead of Blizzard?"

Su Heng continued to explore the functions of the Doomsday Observer.

In addition to observing the types of disasters in advance, the observer also has the function of an electronic map, which can display its own coordinates and nearby mineral resources.

Unfortunately, there are no mines nearby.

However, Su Heng did figure out where he was.

He is in the northern hemisphere, the largest continent on Blue Star.

Su Heng originally predicted that the next disaster would be acid rain, storms, floods and other disasters.

So he focused the upgrade of the safe house on waterproofing, water-proofing, moisture-proofing, and load-bearing.

Unexpectedly, it turned out to be a special disaster.

"Snow turns into water, which will also cause the soil to loosen and the terrain to change drastically, so you're half right."

[It is detected that player Su Heng's safe house level ranks among the top in the world, and the [Recruitment] function is now enabled for you]

[Note: At this stage, the [Recruitment] function is enabled, only for players invited by the system]

"Recruiting?"
