White smoke billowed from the fuel tanks.

It looks like a mushroom on fire.

"Due to some impurities in the fuel tank that cannot be eliminated by the replenishment water, the ship's emergency start device has failed, please find another way to ......" A familiar electronic synthesized voice came.

There was a loud bang.

Luo Chuan's eyes opened instantly, and his blood-red eyes looked around vigilantly.

He hurried into where the fuel tank was, and looked at the billowing white smoke coming out of the fuel tank, almost in despair.

It turned out that the fuel tank was installed on the outside of the spacecraft and was a new type of conformal fuel tank.

The conformal fuel tanks of the "Candy" spacecraft are flanked in the middle of the spacecraft and are nearly twenty-five centimeters long.

Each fuel tank can hold 2.5 litres of water.

Originally, he calculated very clearly that the five liters of water processed in the fuel tank would burst out with huge energy.

The tremendous impetus generated by these energies is enough for the Candy Ship to fly off the ground of Eros, into space, out of the solar system, and finally to the core planet.

It was supposed to be good, but who would have thought that things would change.

By this time, the fuel tank had been reduced to pieces.

The water that I managed to get was wasted.

To make matters worse, the fuel tank was also destroyed.

"It's all my fault." Luo Chuan said secretly, "I forgot that the water prompted by the spaceship is the purity of pure water. ”

The "Book of Water" can also only filter contaminated water to tap water levels.

Tap water, which contains rust, sediment, bacteria, viruses, macromolecular organics, minerals and trace elements.

This quality of water can easily block the fuel treatment process of the fuel tank during the fuel tank treatment process, so as a veteran interstellar voyager, they deeply understand that the quality of untreated tap water cannot be used as a water supply for the ship's fuel tank.

Thinking of this, Luo Chuan slapped his head suddenly, full of remorse, he was too careless.

Luo Chuan returned to the cabin, he lowered his head, and his heart was extremely heavy.

Suzaku, Xuanwu, and Qinglong were still lying well in the refrigerated spaceship cabin.

"I'll take you back to the core planet." Luo Chuan said secretly, looking at the three bodies in front of him, his heart felt a faint pain for some reason.

While in Shaxing, he used the blood matchbox to make Roland successfully perform an interstellar jump.

"I wonder how Roland is now? Before coming to Eros, I heard that she had found Professor Nangong and successfully enrolled in Yuxing High School. "My sister's trip is going well, Luo Chuan thought to himself, "The entire Blue Dragon Action Team has all been destroyed. Now, he doesn't know anything about the core planet. ”

I really want to see Roland!

Luo Chuan looked at the barrenness and endless sand and gravel outside the window, and was in a bad mood.

In this kind of place, it is not known how many more days he will live.

The ship's food storage crates were almost all eaten.

Luo Chuan estimated in his heart that in two days, or even just one day, he might be starved to death.

So, he had no other choice.

Humans will not be able to survive on Eros for long.

He began to calculate carefully, trying to figure out another way.

Another way to get the ship back up.

According to his re-study of the "electronic manual" on the control panel of the "Candy" spacecraft, there was only one way for the ship to restart, and that was to refuel.

"The fuel tank has exploded and shattered." Luo Chuan said to himself, "We must find another way to solve the problem of spaceship fuel." ”

The sun above his head pierced his eyes, and the sun seemed to be the most eternal existence in the entire solar system.

He was so hot that every pore seemed to be steaming and dripping with sweat.

Sun?

Luo Chuan raised his head, and the sun hung straight in front of him like a huge fiery red disk.

Solar energy?

He suddenly thought of a solution, and that was solar energy.

The energy source of solar energy is the energy (mainly solar energy) from the outer celestial bodies of Eros, which is the huge energy released by the fusion of hydrogen nuclei in the sun at ultra-high temperatures, and the vast majority of the energy required by humans comes directly or indirectly from the sun.

In a sense, solar energy is a truly inexhaustible source of energy.

Thinking of this, Luo Chuan felt an inexplicable sense of excitement in his heart.

Solar energy can provide almost everything a spaceship needs.

He was going to build a miniature solar-powered system for the spacecraft himself.

Luo Chuan stepped off the spaceship, devastated and covered with sand and gravel.

As soon as his feet stepped on the gravel ground, he immediately retracted.

The ground is too hot.

Luo Chuan took off his shoes and looked at the soles of his feet that were scorched by the heat of the ground, and couldn't help but feel a little sad.

However, he had no choice.

He had to get the materials to make the solar-powered system.

And these materials can only be found from this Eros star.

He endured the sharp pain under his feet as he moved forward.

I was still replaying everything I had planned in my head.

The basic principle of solar power supply is to convert the collected light energy into electrical energy and store it, and release the stored electrical energy when the load is turned on.

To make a simple solar power system, you also need crystals, crystals that can quickly absorb sunlight and release electrical energy smoothly.

Solar power supply systems are generally made of monocrystalline silicon or polycrystalline silicon cells, regardless of the size of the monolithic cells in the sunlight to generate electricity voltage of about 5 volts, when the light is weakened the voltage decreases.

Luo Chuan lowered his head, he had to find monocrystalline silicon, polysilicon, or other materials that could replace both.

Suddenly, Luo Chuan felt that his body was sliding rapidly, and the feeling of weightlessness in his brain was particularly strong.

"Ah......h

It was pitch black in front of Luo Chuan.

He stretched out his right hand, and Midori instantly transformed into a flashlight, and the light of the flashlight illuminated the path in front of him.

It's a long groove.

The trench was about two meters high, and Luo Chuan's body could barely pass through the trench.

Luo Chuan focused the light of the flashlight on the trench wall in front of him.

On either side of the groove is a series of intricate geometric figures.

"What is this diagram?" Luo Chuan looked carefully, the lines on the wall were chaotic, with different shapes, squares, rectangles, diamonds, and some figures that could not be said to be that kind of geometry.

An inexplicable sense of fear rose in Luo Chuan's heart.

What else is hidden on this planet?

Forget it, don't want to.

Luo Chuan forced himself to remove the graphics he had just seen from his mind and turned his attention to finding materials for the solar-powered system.

He moved the flashlight to the front of his body, and the flashlight illuminated a long tunnel.

This trench is actually a long tunnel that sits beneath Eros.

Suddenly, a voice came.

"Who?" Luo Chuan shouted.

The pores all over the body stood up.
