Mass Transmigration: I Have an Armory

There is no shortage of biogas in the primitive world.

A few months ago, the Chosen One had already discovered biogas.

It's just that the natural biogas is mixed with other gases and is not pure.

Longcheng's research institute spent a long time, first making glass bottles, rubber hoses, fermentation containers and other equipment, then purifying the biogas bit by bit to remove impurities and moisture, and finally prepared ten bottles of pure biogas .

Long Wudi gave one of the bottles to Nan Feng.

Nanfeng: "Only ten bottles in total? Don't you guys in Dragon City use them?"

Long Wudi: "Yes, but don't rush. The research institute is already building an assembly line. Soon, there will be too much biogas to use up."

Nanfeng: "Okay, I won't be polite to you."

Nanfeng accepted the bottle of biogas with peace of mind and glanced at the information on the panel.

To upgrade the hut, in addition to biogas, you also need [Obsidian], [Quartz Stone], [Marble] and other messy things. These are very basic materials that can be found in the warehouse in Nancheng.

He can now upgrade his cabin.

But Nanfeng is now deep in the ancient forest, surrounded by ferocious beasts. If the hut is moved here to upgrade, it will definitely be demolished in minutes.

Let’s go back to Nancheng.

"Lizardman, I'll let you go today." Nanfeng murmured, staring into the depths of the forest.

If you continue to go deeper, it's hard to say whether you can find the lizard people. On the contrary, Nanfeng is likely to be in danger.

Let's forget it, wait until we are stronger, and then fight back...

Silver light flashed, and Nanfeng stepped onto the teleportation array and teleported to Nancheng within the mist.

Nowadays, most of the Chosen Ones are outside the fog, but there are still some Chosen Ones who are not good at fighting and remain in the Southern City in the fog.

For example, those two engineering men.

They had gone to Black Crow City for a while before, but they thought Black Crow City was noisy and chaotic, which was not conducive to their experiments, so they came back again.

Nan Feng had just selected one of the engineering men and teleported him over.

At this time, the sound of discussion between the two engineering men reached Nanfeng's ears.

"According to the law of conservation of energy, we know that the total amount of energy in the universe is eternal. Energy will neither appear nor disappear out of thin air. It will only be transferred from one object to another."

"Becoming stronger essentially means absorbing energy from the outside world into one's own body. Based on the above laws, we can draw a conclusion: when we become stronger, it means that some living beings are getting weaker."

"So, this is why we can upgrade by hunting ferocious beasts!"

south wind:"……"

You can upgrade by hunting ferocious beasts... Is this thing worthy of such a serious discussion?

Another engineering man obviously didn't have much interest in this topic: "Let's build a ship. To the east of the Haoyue Empire is the Sea of ​​Formlessness. It is said that no natives have reached the other side of the sea. Maybe there are people on the other side of the sea. Endless wealth awaits us.”

The first engineering man heard this and nodded: "It makes sense, let's build a ship! According to the formula F float = ρ liquid gv row..."

shipbuilding?

When you two half-assed engineering men build the ship, I might have unlocked the aircraft carrier. Will it be your turn to get the wealth on the other side of the sea? funny.

Nanfeng patted the dirt on his body and ran quickly to his hut.

Cabin, upgrade!

[Rare House]:

[Grade]: B grade

[HP]: 1 million

[Defense]: 10,000

[Characteristics]: +1000 life/minute, +1000 magic power/minute

[Skill]: Demolition - You can move your cabin to another location, with a cooling time of 8 hours.

[Materials required for upgrade]: [Refined Iron]*10,000, [Sand]*100,000, [Water]*10 tons, [Copper Wire]*1,000...

After the upgrade, the appearance of the cabin has not changed at all. It is still the same as the original, a square log cabin covering an area of ​​5 square meters.

But inside the cabin, earth-shaking changes have taken place.

The first is the internal area, which is at least 300 square meters. The living room is spacious, there are many rooms, and there is even a refrigerator, air conditioner and water heater!

"Oh, I bought it. Isn't this too modern?"

Nanfeng walked around his cabin three times, but still found a flaw: "Why is there no computer? I can't help but want to start it!"

But think about it carefully, there is no network here and it can't be started, so forget it.

Take a shower first...

After the upgrade, the hut can restore 1,000 health points every minute.

By the time Nanfeng finished taking a bath, the wounds on his back had healed to some extent, and even the toxins in them had been expelled from the body.

"This recovery speed is about half that of Su Yihan."

"It can be demolished once every 8 hours. You can bring it with you when fighting. Isn't this equivalent to carrying a mobile spring?"

"And the hut has 1 million health points. Even if it encounters Emperor Zun, it can resist twice, right? This time is enough for me to teleport away."

Haha, there is another life-saving skill, cool!

Nan Feng laughed three times and caught a glimpse of the red egg in the corner from the corner of his eye.

This is……
