Faced with the problem of saving people, Zhen Fei came up with a solution: "Make a spacesuit, fill this spacesuit with the lightest hydrogen, and reduce the gravity problem caused by the Golden Planet."

The question is, how do you strip hydrogen out of the air?

It is difficult to do this without the necessary equipment.

Before finding the hydrogen, the samurai below need water and food, someone must send these things down, and if they delay for a while, the already injured samurai will die of hunger and thirst. There are a lot of samurai who come to the Golden Planet, and they are eager to see what the planet is like when it is full of gold. And they don't believe that super-capable monks can be trapped on a planet.

Even Gorgen wanted to see it, and his purpose was the gold. But Zhen Fei immediately rejected Gao Gen's request, and Gao Gen's mana was shallow. If you go down, you may die the fastest.

In the end, two warriors with relatively deep mana were selected to pilot a cloud iron battleship, and they carried dozens of artifacts, which contained some Danshui and food. Under the guidance of the Shenzhou, it slowly flew downward.

This time, the Yuntie battleship had experience, and at the beginning, it used its speed to control the balance of the Yuntie battleship. The atmosphere of the Golden Planet is very thick, more than 5,000 kilometers away, flying in such a thick atmosphere, the Yuntie battleship will soon find no trace of the comrades below.

The Shenzhou commanded the Yuntie battleship to enter in the starry sky, but fortunately with radar and auspiciousness, both of which are advanced equipment for long-range control. In the turbulent atmosphere, the Yuntie battleship swayed like a leaf, and the pilot struggled to fight against the current. Try to keep the landing site as close as possible to your comrades.

Gradually, the rescue Yuntie battleship adjusted its position, and when it was close to the ground, the speed of the airflow was much smaller, and the battleship took the opportunity to adjust its head and raise its head high, so that it would not land immediately, and the people next to it communicated with the pilot in time according to the prompts on the computer and pointed out the direction.

It was really easier for two people to pilot the Yuntie battleship, and later, this mode was fixed. Qiao Bushi, who was proficient in mechanical principles, later added another power system to the Yuntie battleship, installing equipment for rapid climbing, steering, and turning, all due to the hints brought by the Yuntie battleship that fell on the Golden Planet this time.

It's not a bad thing to encounter danger, at least it exposes the shortcomings of the battleship, and the improved Yuntie battleship gradually adapts to various environments and has more powerful capabilities.

The two rescued samurai finally came to the rescued person's side, and they learned how terrible the Golden Planet was. Not only is the gravity too strong, but the temperature is very low. Since there are no stars nearby, the daytime temperature is around minus 100 degrees, receiving a pitiful amount of light and heat from the stars from farther away. At night, after the Golden Planet has turned, the temperature plummets to about minus 500 degrees.

It's cold to the bone.

This is another feature of the Golden Planet.

It's a harsh environment that costs human lives.

Seeing that his comrades-in-arms were about a hundred meters away, the Yuntie battleship was quietly moored and motionless. The two rescuing samurai watched and could not pass, and they felt that their bodies were about to stiffen. One of the two samurai was named Shu Aiwu and the other was Ke Zhan, and the name of the rescued samurai was Yuan Li. They belonged to the same brigade of samurai, and they were also considered comrades-in-arms, and they were together many times to defend themselves against the enemy.

Shu Aiwu smiled bitterly and said to Ke Zhan: "That's it, I use the five-flavor real fire to surround my body, isn't it just a hundred meters?" I'll rush over to it. "At such a short distance, the cold can't take away a person's body temperature at once, and there is also the protection of the five flavors of true fire, which should be able to realize the work of rescuing Yuan Li.

But Zhen Fei, who was far away on the Shenzhou, disagreed, and said: "Don't be careless, you have to contact Yuan Li, he can open the hatch for you in time to answer." ”

shouted Yuan Li's name a few times, only to find that under the low temperature, Yuan Li had fallen into a coma and couldn't hear the shouting at all.

In this way, the situation fell into a dilemma, if he didn't take over Yuan Li's Yuntie battleship, the computer power inside would run out, and at that time, the situation would be even worse. The injured Yuan Li could die at any time. Zhen Fei on the Shenzhou was in an extremely bad mood, and said angrily: "No matter what, you have to save Yuan Li, the battleship of the Shenzhou is large and can effectively resist the cold." ”

But this suggestion was immediately criticized by everyone: "The volume of the Shenzhou is too large, the weight is too heavy, and it can only fall faster and heavier when it rushes into the Golden Planet, and if the Shenzhou cannot be rescued, the entire army will be in a dilemma." ”

In the end, Shi Hong suggested: "If it really doesn't work, then set fire to Yuan Li's battleship, if you use the Five Flavors True Fire, the Yuntie battleship can still withstand this level of flame burning." ”

With the attitude of trying it out, Shu Aiwu opened the hatch, and with a wave of his hands, he released two bursts of fire, enveloping Yuan Li's battleship, and then, the hatch quickly closed. At this moment, Shu Aiwu and Ke Zhan felt like they were falling into an ice cellar, and they were shivering all over their bodies.

The bitter cold lives up to its name.

After Yuan Li's battleship was roasted by the fire, his body temperature quickly rose, and the person woke up slowly. opened his eyes and looked around, found Shu Aiwu and the others, smiled and waved his hand. Shu Aiwu and Ke Zhan were overjoyed, and said into the microphone: "Let's go over immediately, you just need to open the hatch and let me in." ”

"Okay." Yuan Li said with difficulty.

Shu Aiwu said to Ke Zhan: "I'll send you into the storage space, I won't do it, you have to continue to complete the task." ”

"Okay, I wish you success." Ke Zhan hugged his comrades tightly and agreed to Shu Aiwu's proposal.

Shu Aiwu stood up and did a warm-up exercise, opening the blood movement in his whole body, and then opened the hatch and rushed outside, due to gravity, he fell to the ground all at once. Shu Aiwu is also a very strong person, although he can't stand up, he still surrounds himself with the five-flavor real fire, not from the invasion of the cold, and then, lying on the dusty ground, he put the battleship and Ke Zhan into the storage space, this storage space is shared by him and Ke Zhan, and Ke Zhan who enters the storage space can also enter and exit freely.

Shu Aiwu, who has participated in the Guards Division for four years, is an extremely resolute figure, and he completed the process of arriving at Yuan Li's battleship in a crawling posture. Such a harsh environment and scene stunned everyone.

The worse side of the starry sky is displayed in front of everyone, and many people have been educated from this picture and dare not take it lightly. No matter how strong they are, they are still like babies in front of the power of nature, because the starry sky is too big, and that kind of power can only be changed by immortals, they are just monks, just a little stronger than ordinary people.

From a distance, a planet is so small that it seems to be able to hold it in your hand, and if you land on any planet, you will find that you are an ant.

Under the auspicious lens that everyone was worried about, Shu Aiwu completed a short crawl of 100 meters. Yuan Li, who was already in tears, opened the hatch and pulled Shu Aiwu, who was about to freeze, into the cabin of the battleship.

Ke Zhan in the storage space was like a year, and he couldn't wait to jump out, he didn't know the situation outside, and he came out with the five flavors of true fire, in his thoughts, Shu Aiwu might have been frozen stiff now. After coming out, I found that in the cabin of the battleship, I immediately put away the five-flavor real fire.

Hurriedly treated the two comrades-in-arms, Yuan Li mainly hadn't eaten for two days, he was cold and hungry, and with the shock injury, he was already at the end of the crossbow. Shu Aiwu was mainly frostbitten, and there was no major problem elsewhere.

Ke Zhan sent his two comrades-in-arms into the artifact space, and then he also entered the artifact space, and the temperature in the artifact space was a little better, as well as delicious food and wine. They are safe for the time being.

It is more difficult to produce hydrogen, and in the absence of technology accumulation and experimental equipment, Sun Yingji's research has not made progress.

Zhen Fei said: "In fact, water is a compound of hydrogen and oxygen, as long as the water molecules are separated, it is hydrogen and oxygen. ”

This information is known to anyone who knows a little bit about chemistry. Zhen Fei hoped that Sun Yingji would once again unleash the ability to extract the essence and extract the hydrogen from the water, but Sun Yingji could not do it.

Zhen Fei's words were a hint to Sun Yingji, and three days later, Sun Yingji finally succeeded in extracting the spirit from the water vapor, stripping hydrogen and oxygen from the water molecules.

Water vapor is a form of existence, and only in this form is that water and qi are the closest to it, and Sun Yingji can use the means to extract the soul.

After stripping the oxygen is significant, and below, hydrogen is of course very light, on top.

After the experiment was successful, a large amount of water vapor was created using a huge pot that was burned with a five-flavor real fire underneath. The entire manufacturing process is set up in a storage space, after turning water into gas. This storage space was delivered to the outside of the Shenzhou.

The cold temperature immediately turned the gas into liquid, and the oxygen turned into a pale blue liquid at minus 215 degrees Celsius. At minus 253 degrees Celsius, hydrogen becomes a colorless liquid, and at minus 259 degrees Celsius, hydrogen becomes a snowflake-like solid.

A large amount of hydrogen was obtained, and then the solid hydrogen gas was put into the clothes made of snow cotton, and the melted hydrogen immediately worked, and the people wearing the clothes instantly rose into the air inside the Shenzhou, which is a gas 14 times lighter than air.

Next, another Cloud Iron Battleship was sent into the Golden Planet to rescue the two battleships and three people below.

When Shu Aiwu and the three learned that there was already a way to rescue them, they all cheered and celebrated with wine glasses.

A week later, the preparations were ready. Entering the Golden Planet was a company, on the surface there were only two pilots, according to the tips of the Shenzhou mothership carefully slid down and landed, this time, their speed and accuracy have been significantly improved, just docked next to Yuan Li's battleship, and then, the warrior waved Yuan Li and the others together with the Yuntie battleship into the artifact space, from the auspicious lens, only one Yuntie battleship was on top of the Golden Planet.

Then, the samurai went out during the day, after all, the temperature during the day was only more than 100 degrees below zero, and the spacesuit made of hydrogen played a role, and the powerful hydrogen pulled the samurai's body to stand up. And they can fly on the Golden Planet.

More than 100 samurai took action, using powerful magic weapons to cut open gaps in the planet, and threw very pure gold ore into the storage space.
