Although Ark has always planned to save fuel, the lack of fuel reserves in the Ark was exposed during this crisis.

In order to maintain mobility, the Ark has maintained a high-speed navigation in the entire crisis. In just a short period of time, it has consumed 5% of the Ark's fuel reserves. With the consumption in the past, the Ark's fuel reserves are now less than 70%.

If supply is not carried out, unless Lu Yu unlocks a major technology like a nuclear reactor in the copy, the Ark will really be out of ammunition and food.

Lu Yu had some considerations before, such as directly building an oil mining platform and refining a floating island for oil.

But the ark was always in a sailing state, and these two items could only be rejected after a little thought.

There are also large quantities of recyclable and renewable energy sources, such as wind and solar.

Now Lu Yu has actually made a wind turbine, and relying on the enhanced version brought by his "Self-free BUFF" to learn from one example and there is no technical problem in manufacturing solar panels based on the knowledge in his mind.

But both of these energy sources have their limitations. For example, the power generation power of wind energy varies. In order to make good use of its power generation capacity, the ark must also cooperate to build special power facilities to store and stabilize electricity use.

The solar power generation technology that Lu Yu has mastered now has not yet been able to break through the technical ceiling mastered by mankind in this era, which means that the conversion rate of the solar panels he manufactures is very limited.

With the surface area of ​​the ark, even if the solar panels are covered, the power generation is limited.

And silicon, the basic raw material for manufacturing solar panels, is not much easier to obtain than oil when the world is covered by the sea.

Whether it is wind power or solar power generation, it also has a certain impact on the maneuverability and protection capabilities of the Ark.

Both will affect the appearance of the ark during cruise, and the combat state is easily destroyed by the enemy.

After some consideration, Lu Yu thought of the ethanol gasoline that was once popular on land.

The engine used by Ark is a diesel engine, which can theoretically be prepared for biodiesel for alternative combustion.

Originally, Lu Yu planned to design and manufacture a device that can ferment algae starch that can be mass-produced and then convert it to prepare biofuels.

But although the end of the world is hard, it is fair.

As a hard worker, not only Lu Yu received a great reward and made great progress in his ability, but Arnold also improved a lot of his abilities through hard work.

While working hard in the planting workshop, he accidentally unlocked microorganisms that can produce large quantities of alcohols.

With this microorganism, the production process of biofuels is greatly simplified.

On the one hand, the production device can save valuable space after fewer steps, and on the other hand, the production efficiency is greatly improved.

Lu Yu's work efficiency is amazing. Now he has mastered the ability to master principles, design, and build one-stop.

This construction also brought some twists and turns. Lu Yu initially described an extremely space-saving design in his mind, which can be said to have used the length, width and height of the available cabin without wasting any waste.

Then after he drew the Scan diagram, Arnold looked at it for a long time and reminded: "Daniel, I admit that this is an extremely exquisite design. Even in the eyes of me, as an outsider, you can see the beauty of this mechanical one.

But I think it is necessary to remind you that the future operation and maintenance of equipment may not be entirely done by you.

Our ordinary skilled workers may not necessarily have the ability to maintain this extremely complex equipment."

Arnold's words made Lu Yu wake up suddenly. As his design and construction capabilities improved, he was increasingly pursuing the beauty brought by the ultimate craftsmanship.

However, this beauty is so unique that few people can go deeper except himself.

The biofuel production line he has initially designed has indeed saved cabin space through three-dimensional design, but for this ultimate beauty, too many craftsmanship that only he can do is used.

This is not a good thing for the long-term use of the equipment. After all, it is impossible for him to do the maintenance and operation by himself.

Change to the direction of easier use and easier maintenance operation.

The more stupid the change, the better the maintenance and stability will be.

The production line is rearranged to remove the complex processes, exposing the internal structure that was originally hidden for beauty, but instead has a unique aesthetic of mechanical punk style.

Unlike the weapons and equipment made by Lu Yu before, this biofuel production line was designed and manufactured by Lu Yu from beginning to end from the beginning.

Therefore, the quantity and complexity of the production line seem to be far less than those fine weapons and equipment, but Lu Yu spent five days building and polishing to make a work that satisfies himself.

Not everyone can watch Lu Yu and do it himself. Although everyone on the boat has a feeling of admiration for Lu Yu, the magical ability of the Reincarnator is still too powerful to them. If they are allowed to see it directly, I am afraid that the internal thoughts of the Ark will go in a direction that Lu Yu does not want to see.

Only Arnold and Xiaopang Brother can get Lu Yu's permission, and help him serve tea and water or simply appreciate his miracle.

When Lu Yu started making a piece of equipment, his hands could even perform more than a thousand fine operations in one minute.

In the eyes of Xiaopang Brother and Arnold, it was that Lu Yu's hand turned into a ball of light composed of afterimages, and then in a moment, he completed a complex and precise part from scratch.

Little Fat Brother sighed: "Daniel, you are simply playing technology into magic."

Lu Yu just smiled faintly for his compliment to this guy. Now the production line has reached a usable state, so just start production step by step.

His attention has also begun to shift to other things and said, "Although it is said in the conventional rules of the Reincarnation, I should not ask about your private affairs.

However, although I was a little busy during this period, my abilities have been greatly improved.

I think Arnold has also made considerable progress. Fat Brother, how are you doing?

We have been a companion who has been working with for so long, and you are still my tenant. If you have anything to help you, just say it.”

Brother Xiaopang drank all the tea in his hand and said calmly: "This time I have successfully accumulated a lot of survival points, but my rank is so ok, it's impossible. The difficulty may be very high, but it's quite interesting.

In a sense, I am also practicing myself. Maybe this is what Buddhism says, don’t seek outside or save yourself?
