The signal was cut off.
The living room was silent.
In just a minute, a regiment of soldiers was almost instantly swallowed up.
Those monsters were too terrifying.
If all of them were to come out, they believed that they would occupy the entire city by daybreak.
Tomorrow, this place might turn into ruins.
Fortunately, there was still a shelter here.
Xiao Fei's big eyes were filled with fear. He hugged the beagles and weakly looked at Ye Xiu: "Brother, what should we do?"
Ye Xiu wasn't worried because he knew that the Cataclysm would come. He just wanted to know what kind of creature it was. Up until now, he hadn't gained much.
So he decided to observe for a few days.”
"That's right!" His father also agreed. He looked at the luxurious underground fallout shelter and smiled."It's very safe here, much better than the official shelter. These monsters should be active in the Urban area for the next few days.”
"Yes!"
Xiao Fei nodded obediently. He knew that this was the only way now.
Although his mother, Qin Yun 'er, was very afraid, she still comforted the little girl and said with a smile,"It's fine. We have a lot of food here. Staying here for half a year shouldn't be a problem. Oh right, Little Xiu, I've also prepared some seeds for vegetables and grains.”
"Of course!" Ye Xiu nodded. He had expected this question.
Therefore, he left behind a 50-square-meter planting base. There was no problem growing all kinds of plants. This was a different kind of greenhouse.
……
Soon, the night passed. The four of them slept together and did not separate. Even though this place was very safe, fear was the most important factor.
The next morning.
Ye Xiu realized that all the computers and networks had lost their signal.
In other words, he had lost contact with the outside world.
Of course, he believed that this wasn't just his family's situation. All the networks and cables in this city had been destroyed.
The entire city was probably in a state of panic.
However, he was not worried and continued to live in the underground fallout shelter.
Everything he needed was here, and staying there for half a year was not a problem.
……
On the third day, nothing happened.
On the fourth day, nothing happened.
Until the fifth night.
……
Suddenly, there was the sound of a collision outside.
Bang!
Bang!
After a series of collisions, Ye Xiu wasn't worried that the titanium alloy door would be knocked open.
Therefore, not long after.
The monsters gave up and left.
……
This made Fei Fei heave a sigh of relief. His beautiful big eyes were filled with fear.
Although his father was usually carefree.
However, at this moment, he also took on the responsibility of being the pillar of support and comforted the little girl.
Ye Xiu saw this, but he didn't say anything.
However, he was also afraid that one day, this thing would not be able to defend itself.
Therefore, the most important thing now was to upgrade the fallout shelter and the research center.
He looked at his remaining 110 points!
……
Thus, Ye Xiu chose to come to the Research Base.
After scanning his identity, he opened the research project of the research base.
[Combat Drone: Level 3:10kg of pure iron! 1kg of copper! Gold 0.002kg! [Equipment: Requires two nuclear energy crystals!]
[Research Base: Level 1!]
[Research Items: Bullets, Desert Eagle, Scout Drone!]
[Upgrade to the next level requires 20 points!]
Would you like to upgrade?
"Yes, sir!"
Seeing the stats of the research base, Ye Xiu didn't hesitate to confirm it.
He needed combat drones now because he needed level points to do anything. However, his 10 level points per day were not enough.
Therefore, he had to hunt underground creatures to obtain more leveling points.
Of course, he wouldn't go out by himself. He would be a fool.
Therefore, he tried to see if he could use the combat drones to hunt!
Ding! Congratulations to the host for successfully upgrading!
Name: Research Base!
[Level: 2]
Area: 200 square meters!
[Researchable Items: Desert Eagle, bullets, reconnaissance drones.] AK-47 automatic rifle! M4A1 automatic rifle, mini reconnaissance aircraft!
[Upgrade to next level: 30 points]
Do you wish to continue upgrading?
……
"Yes, sir!"
Ye Xiu chose to level up again.
Soon, he heard the system notification. The research base changed again and doubled in size.
It was already four hundred square meters.
On the basis of the original scientific research.
Combat drones were added!
……
Unlocked items, nuclear drones, helicopters, fighter jets, tanks, submarines, warships, independent satellite equipment, teleportation portals, spatial portals, and so on!
Of course, Ye Xiu also understood that this was still very far away for him.
Therefore, after the upgrade was completed.
He first chose to build combat drones.
This was a miniature drone similar to a reconnaissance drone. However, on top of the original foundation, it had added various means of attack. At the critical moment, it could even activate the nuclear power system inside, causing terrifying damage in a radius of nearly a hundred square meters!
However, the consumption of a combat drone was still very high.
On the basis of not having any materials.
It required eight energy crystals to exchange.
With the addition of two attack nuclei.
One combat drone required ten energy crystals.
That was ten upgrade points.
And Ye Xiu currently had 60 points left!
Therefore, after thinking about it, he decided to exchange for two!
The remaining 40 points were used to upgrade the Sanctuary.
……
Name: Sanctuary!
[Level: 3]
Area: 400 square meters!
[Buildings: Research Base]
[Upgrade to the next level requires 40 points!]
[After upgrading, the fallout shelter will be expanded to 800 square meters, and the titanium alloy door will be upgraded to a double-layered titanium alloy door, 1.2 meters thick!] The thickness of the wall was increased to 1.2 meters, and the foundation sank another ten meters. There was an independent elevator!
Would you like to upgrade?
……
"Upgrade!"
Ye Xiu didn't hesitate to choose yes.
The next second, Ye Xiu saw a blue blueprint appear in front of him.
It was the plan of the entire fallout shelter.
The difference was that apart from expanding the area, it could also be expanded up and down, which meant that it could be transformed into an underground building!
Therefore, he thought about it and chose to continue building.
This way, in addition to the upper floor, there was a second floor.
The third level was the research base.
……
After doing all this, he was relieved. Even if all the monsters attacked together, they probably wouldn't be able to break through the 1.2-meter-thick titanium double-layered iron door!
Now that he had the drone, it was time for him to check the situation outside.
