Strips of illusory green scanning light extended from Sumo's feet and spread far away.
When the limit is reached, the light returns again, and the progress increases by 0.1%.
Taking advantage of the binding, Su Mo opened the wooden door and looked in.
Behind the wooden door, there is a ladder made of mud.
Going down the stairs and waiting until the silent count reached fifteen o'clock, the eyes suddenly became bright.
With the help of the faint sunlight coming from the entrance of the cave, Somo could barely see the structure inside.
The ground and roof paved with planks constitute a stable foundation, ensuring that the huge underground pothole will not collapse.
"Bet right!"
Su Mo was delighted.
It is certainly beneficial to choose the ground, and it can gain some convenience in the early stage of development.
But he has never forgotten one thing, with the tools for making pages, it is not difficult to build a house on the ground.
But if you want to build a shelter underground, you must not only rely on tools, but also have sufficient architectural knowledge to ensure the stability of the underground structure.
Otherwise, if you dig indiscriminately, you may die in a landslide at night without knowing how to die.
Seeing that the binding progress bar of the doomsday survival system was still rising slowly, Su Mo simply sat on the stairs and opened the chat panel while conserving his energy.
Perhaps, others also have this so-called doomsday survival system?
I watched the world channel for a while, and then turned on the regional channel and watched it for a while.
No one mentioned it.
"It seems that I am the only one with two systems?"
Somo came to a conclusion.
At this time, most of the speakers on the World Channel and the Regional Channel chose the above-ground refuge, and only a few chose to go underground.
However, those who chose to go underground only complained about the tragedy of the underground, and then began to communicate to find supplies.
With no reference and no idea what it was, Su Mo could only continue to wait.
Fortunately, the improvement of the progress bar was very stable. After more than ten minutes, the green light finally stopped scanning. After returning to Sumo's body for the last time, a crisp prompt sounded:
[The doomsday survival system is successfully bound]
[First time binding reward: 100 survival points]
[Scanning the living environment of the host, during the evaluation of the survival points, 5 survival points were obtained today. 】
[Final settlement, you have obtained a total of survival points today: 105 points! 】
[Remaining survival points: 105 points! 】
As the reminder sounded, a large piece of scattered memory was transmitted.
Originally, the doomsday survival system was a product that he could bind in the previous world. Unfortunately, the information was blocked at that time, and the country did not notify all the people to enter the shelter until the day before the disaster.
Naturally he also didn't have time to dig into the personal shelter and thus missed the system binding.
After coming to this world, if the survival game panel is a game panel that everyone has and can use, then the Doomsday Survival System is a modifier, and only Sumo owns it.
According to the doomsday survival system, every day you survive, you can get a certain amount of survival points.
Survival points are similar to points in the game and cannot be directly exchanged for items.
Its function is similar to the item upgrade function in the game, but the upgradeable scope is more comprehensive.
As he learned more and more, Su Mo pressed the excitement in his heart and fixed his eyes on the simple underground survival base:
【Personal refuge】
Owned by: Sumo
Space: 100㎡ (floor height 4.2m)
Completeness: 100%
Facilities: None
Introduction: The shelter is extremely simple, without any living facilities, at best it can be regarded as a small tomb in the last days.
Looking at the introduction on the panel, Su Mo's heart moved, and he turned his head to look at the only wooden door in the shelter.
【Refuge door】
Effect: slightly anti-theft, slightly anti-radiation
Upgrade Direction 10: Increase the thickness of the wooden door, increase the sturdiness of the wood, slightly fireproof and waterproof ([-])
Upgrade direction 60: change the material, upgrade the wooden door to a stone door, greatly increase durability and other attributes ([-])
Evaluation: You don't want to live in the last days with a wooden door, do you?
After observing for a while, Su Mo barely figured out how to use the Doomsday Survival System.
In addition to purely relying on survival points to upgrade the system, users can also provide materials, which greatly reduces the survival points required for the upgrade plan.
For example, to upgrade a wooden door to a stone door, if he can provide 10 units of stones and 2 units of wood, the survival points required for the upgrade will drop to 5 points.
Survival points can be used as any substance, but the conversion efficiency is definitely not as good as the original substance.
So as long as enough similar substances are provided, and the survival point plays a role of transformation and assimilation, the consumption can be greatly reduced.
After understanding these situations, the pressure of survival that had been pressing on Su Mo's heart was finally much less.
"I want to create a strong enough shelter before my parents and sister put it in"
"Before that, let's solve the material problem first"
Clenching his fist secretly, Sumo walked out of the shelter along the steps.
Drinking water, food, these are the primary concerns.
Fortunately, now that the survival system is in place, a general development route has appeared in Su Mo's mind.
First, he came to a small tree and used his own body weight to break the branch. After putting it in the inventory, a reminder came out.
