[Record]: Player is detected to have a complete safe house core. Do you wish to absorb it?

When he saw the words jump out, Su Mo concentrated and used his mind to click yes without hesitation.

Suddenly,

The tortoise shell on the hand began to shake violently. To be specific, the tortoise shell produced--

A resonance!

The whole shelter seemed to be moving, with small tremors one after another.

With each passing second...

The frequency of the shelter's vibration seemed to be getting closer and closer to the frequency of the tortoise shell shaking in his hand.

With his naked eye, he could see the tortoise shell begin to crack and melt, one piece at a time. They melted into a blue liquid, falling from Su Mo's palm, and sliding all the way onto the stone floor.

Boom!

The earth began to tremble, and the entire shelter felt as if there was an earthquake taking place inside as it began to sway rapidly.

The next moment, Su Mo looked at the magical scene in front of him and was stunned.

[Record]: You have successfully absorbed the damaged safe house core.

[Record]: Your shelter area has increased.

[Record]: Your current shelter area is 110 square meters.

His originally familiar shelter went through a sudden metamorphosis. It was as if the shelter had eaten too much and grown fatter, with ten square meters appearing out of thin air.

In the extra space, there were a few things neatly arranged.

"Bark bark bark!"

Oreo, who was still lying on the ground and resting, looked like it had seen a ghost as it looked around at the extra space and barked due to the unfamiliar smell.

Su Mo walked quickly toward the extra space and began to look at the things on the ground.

There were around a dozen items.

The first was three shirts with blood stains on them. They were brightly colored and there was even a pink bear mask.

Beside the clothes were two tools. A stone axe and a stone shovel.

Compared with the rich and outspoken Su Mo, the man's equipment looked pitiful. He could not believe where the guy got the confidence to try and raid his shelter.

Fearing that there would be some hidden poison, Su Mo did not dare to use his hands, so he cautiously picked up the clothes with a stone spear and uncovered the items hidden underneath.

There were around a dozen more items as well.

There was some beef jerky that he bought on the market on the first day before. It seemed like a lot and was at least 300g.

There were four boxes of milk, a whole loaf of bread, two corn sausages, old yogurt, and a bottle of unopened Pepsi.

There were also two bottles of mineral water that have been opened but not finished yet.

"I've struck gold! I've struck gold!"

After using the game panel to confirm that items' properties were fine, Su Mo looked incredibly happy.

It was no wonder that those people did not choose to develop their own shelters normally and instead chose to steal from people.

The person who steals would earn more than the person who worked hard.

Just those items would sell for at least a few liters of water if they were listed on the trading market. Even so, they were priceless!

The food currently sold in the market was mostly bread that required a lot of water to be edible and mutant beast meat that was dry and difficult to swallow.

After days of looking through the listings, Su Mo did not find any food item to splurge on the market.

Unexpectedly, those boxes of items actually fell down from heaven for free.

"Since fusing a damaged core can increase ten square meters to my base, I'll fuse all of them!"

After taking out the remaining three damaged cores and selecting them one by one, his safe house began to shake again.

[Record]: You have successfully absorbed the damaged safe house core*3.

[Record]: Your shelter area has increased.

[Record]: Your current shelter area is 140 square meters.

[Record]: Your shelter level has been upgraded. Please enter the game panel to check.

After shaking for a while, at the same spot, a total of 40 square meters of space was added into the shelter and the shelter which originally looked empty became quieter and more serene.

There were a lot of things piled on the ground randomly. Just by looking at it, Su Mo felt so happy that he felt like he was going to faint.

At the innermost corner, there was a device that looked similar to his thick color television.

Su Mo was not unfamiliar with the device at all. It was exactly what he wanted from for a long time, what he dreamt about at night--

A generator!

At that moment, Su Mo could not suppress the excitement in his heart. It was as if he had seen his little lover as he walked quickly to the machine.

It was painted sky-blue throughout the entire body.

There were three thick black iron pipes surrounding the main body of the generator which acted as a side frame to protect it against dust.

When he lowered his head and saw the generator's main body, Su Mo's eager heart immediately became cold.

There was a label that said that it was a Siemens Wuxi diesel generator and those people probably got it after killing mutant beasts or from robbing someone.

However, the problem was that a spear had pierced through the generator's fuel tank and there was a large hole, exposing the inside of the fuel tank.

As Su Mo crouched in front of the generator, he began to carefully recall the generator principle he had seen in the miscellaneous books from his university's library.

It was simple for a generator to generate electricity:

In the diesel engine's cylinder, clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel fuel sprayed from the fuel injector. Under the upward squeeze of the piston, the volume is reduced, and the temperature rises rapidly, reaching the ignition point of the diesel fuel.

The diesel fuel is ignited, and the mixed gas burns violently. The volume expands rapidly, pushing the piston down, and is called work done.

Each cylinder performs moves in a certain order and the thrust from the piston becomes the force that rotates the crankshaft by pushing the force through the connecting rod, thereby driving the crankshaft to rotate.

By installing the brushless synchronous power generator coaxially with the crankshaft of the diesel engine, the rotation of the diesel engine will drive the rotor of the generator. By using the principle of electromagnetic induction, the generator will induce an electromotive force and current will be generated to the load of the closed circuit.

After thinking about it, Su Mo breathed a sigh of relief.

Fortunately, the thing that was kaput was not the most important part, the current control device. If that part broke, the generator would have been useless.

Since it was just a hole in the fuel tank that was damaged, he just needed to repair it with a few points!

He stared intently and focused his attention as Su Mo called up the system internally. After that, he looked at the diesel generator.

[Diesel Generator (damaged)]

Efficiency: 300kw (300 kwh at full load)

Fuel consumption: 230 grams per kilowatt hour (82L/h at full load)

Description: A diesel generator produced by Siemens Group in Jiangsu, Wuxi that has never been used. The circuit is functional, but the fuel tank is damaged.

Upgrade option 1: Replace and repair the core components of the generator, enhance the efficiency of the generator's power supply, reduce the power consumption of the generator. Survival points required (1680).

Upgrade option 2: Change the working mode of the generator into a biomass fuel power generator. Survival points required (6500).

Introduction: Am I yours? You're my You Le Mei! No, no, no! I want to be your generator! 

"D*mn, that's so expensive. 1680 points? I'll have to save up my points for at least ten days to half a month to upgrade it!"

After he shook his head, he gave up the crazy idea of ​​accumulating his survival points to upgrade the generator.

Su Mo began to ask for another upgrade option internally.

By changing it into single-category small function upgrade options, despite it costing more and not as cost-effective as the overall upgrade in the long run, he had a shortage of survival points, so it was a good way to solve his urgent needs.

"Even though it's going to be more expensive, so be it. As long as I can repair it, I'll be able to develop my base at double the speed."

A burst of light flashed, and the original upgrade options began to change.

[Diesel Generator (damaged)]

Efficiency: 300kw (300 kwh at full load)

Fuel consumption: 230 grams per kilowatt hour (82L/h at full load)

Upgrade: Repair (130), increase volume (50), increase conversion efficiency (300), change material (420), change energy supply mode - biomass (4450)...

"It needs 130 to repair it..."

The price was reasonable and was not too high, but Su Mo was not able to afford that much for now.

Today, he had a total of 153 points. It cost him 20 points to upgrade his raincoat and after using 65 points to upgrade the passageway, he was only left with 68 points.

"We'll have to wait until tomorrow to repair it, then."

After Su Mo calmed down the excitement and anxiety in his heart, he began to gather his supplies and count the spoils of his battle.
