"Water." Rosen said calmly: "I already knew it when I was in junior high school."
"You are right." Mark said: "Now, I still have water in my aircraft. I used hundreds of liters of unused hydrazine (Note) to catalyze it with iridium, and it would decompose into nitrogen and hydrogen. As long as I gathered the hydrogen into a small area and ignited it, I would literally reshape human history."
"Yes." Rosen said with a smile: "Maybe it's to reshape yourself. Don't forget that the combustion of hydrogen and oxygen will also produce a lot of heat. If it cannot be dissipated, it will explode..."
"Don't be such a spoiler. I have made careful calculations and there will definitely be no problem." Mark said confidently: "There is never any harm in lighting hydrogen. FAA hates fire, because In general, fire is a human killer in the sky."
"So everything they sent here is flame retardant, obviously not including Martinez's personal belongings."
As he spoke, Mark took out a wooden cross and shook it towards Rosen, saying: "With fire, all problems will be solved."
After filling the jar with hydrazine, Mark He then drove Rosen back to the living cabin and followed him while operating and explaining. He looked like a chatterbox who had been bored for a long time but had nowhere to talk.
"Hey, Mark, have you ever said that you are very suitable to be a teacher?" Rosen said.
“Not really.” Mark said with a smile: “If I can return to Earth alive, I will follow your suggestion and become a teacher in a university to teach them how to grow potatoes on Mars. Survive, and how to get along with the Chinese."
"Haha." Rosen laughed after hearing this.
Mark put on goggles, ignited the wood chips chipped from the cross, and prepared to use the flame on it to ignite the hydrogen produced by the decomposition of hydrazine, so that it would burn calmly in an aerobic environment, thus Get water.
I have to say that Mark’s thinking is very smooth.
But in operation, it's a bit... a slight difference.
At first, the hydrogen gas did burn as he expected. Mark was extremely excited and cheered.
When Rosen saw this, he grabbed his arm and teleported him without saying a word.
The reason why Rosen didn’t rely on his legs to retreat or dodge was because he was afraid of being too late.
Of course, the more important thing is that his teleportation is so smooth now, which is much more convenient than running and jumping.
In order not to scare Mark, he did not teleport too far, only four or five meters.
Bang.
The next moment, there was an explosion and flames.
Because Rosen came to the rescue, Mark was not blown to the ground like in the original plot.
Although the situation was not that serious at the time, otherwise he would have been dead.
"Wow, Rosen, did we go directly from there to here just now?" Mark pointed to the place where he was standing just now, and then looked at the current place.At the position, he looked at Rosen and said uncertainly: "Kung Fu?"
"No." Rosen shook his head and said, "Magic."
" Stop it." Mark didn't believe what he said and said, "Anyway, thank you for saving me again. Did you expect it to explode?"
"Almost. "Okay." Rosen nodded and said, "You are thinking very well, but you have overlooked one thing. Our breathing also contains oxygen. If it accumulates in the cabin, it will eventually burn with hydrogen. When calculating You may have ignored it."
"Yeah." Mark rubbed his ears and said, "Okay, I admit that I am a bit stupid, but it doesn't matter. When my ears stop ringing, I will continue to try."
Rosen nodded and encouraged: "Come on."
With the experience of failure, Mark's next experiment of hydrogen and oxygen combustion to produce water is natural. Completed successfully.
To celebrate Mark's success, Rosen treated him to a meal of fried noodles and some home-cooked dishes.
Judging from Mark’s expression when he was eating, he seemed to have an average acceptance of fried noodles, but he still ate them cleanly.
Obviously, the lack of food had made him feel stressed and he began to change.
While Mark was busy serving his potatoes, Rosen was not idle either.
Farming is not difficult for him who is proficient in farm work at level 4, and naturally it does not take up much time. Apart from watering regularly every day, there is basically nothing else to do.
After all, there are no pests on Mars, and even if there were, they might be eaten by the poisonous flower vines that guard the glass greenhouse every day.
In addition, there are no weeds here, so there is no need to weed or anything.
So with nothing to do, Rosen rode an electric tricycle around Mars.
Due to the limited power of electric tricycles, they can only travel around twenty or thirty kilometers at most.
It was okay at first. Lawson was quite fresh, but after a long time, he got bored, so he gave up the electric tricycle and started running around by flashing.
Occasionally I don’t want to walk anymore, so I sit on the Clay Stone Demon’s shoulders and let it carry him and run wildly on Mars.
Before traveling, Rosen had collected many maps on Mars.
But after he arrived, he discovered that these maps were either incomplete or biased. If his map expertise hadn't been a vegetarian, he might have really gotten lost on Mars. It is very likely that we will get an achievement such as the first time someone got lost on Mars, which will definitely leave a shameful page in the history of human Mars exploration.
It is worth mentioning that the reason why Rosen is obsessed with exploring is not just because he has nothing to do. The more important thing is to earn achievements.
Not long ago, when the seeds he planted began to sprout one after another, he achieved many achievements one after another.
For example: the first plant to be planted on MarsThe person who invented chicken feathers, the first person to grow corn on Mars...
Although achievements such as these are basically useless, they neither give attributes nor reward the opportunity to extract skills or items. But you can get a medal.
Although the medal is still a blank slate with no attributes, it looks good.
What’s more important is that it satisfied Rosen’s desire for collecting, so in order to accumulate more new medals, he began a journey of exploring Mars and gaining achievements.
It has to be said that on such a planet where no human has ever set foot before, no matter what Rosen does, he will probably achieve success.
Achievements are so popular, but unfortunately almost none of them are useful.
But Rosen enjoyed it.
Of course, in addition to such useless things, Rosen also tried to do some serious things, such as working on the map of Mars while wandering.
He definitely didn’t know how to survey and map in the past, but now that he has level 3 map specialization and an m44 compass that never loses his way, everything has become much easier.
As Rosen spent more and more time wandering outside, the roads he traveled became farther and farther, and his range of activities expanded crazily.
But he still returns home on time every day and never stays out overnight.
The reason is that his teleportation continues to upgrade due to his frequent use.
“Teleport, level 5, you can reach anywhere within 10,000 meters.”
“Your map expertise has been upgraded to level 4, and any map you have seen will be It will guide you in the right direction, and the terrain and landforms you have seen will automatically form a map in your mind for you to consult at any time."
"Due to the correlation between teleportation and map specialization, new ones are derived. Skill: Delivery, as long as you have and loaded a detailed map of a certain area, you can complete accurate delivery within a certain range even if you have never reached the area."
"Current level lv1, With you as the center, any coordinate point within a radius of 500 meters can be delivered. If there are obstacles near the delivery location, the landing point will be slightly adjusted to ensure your safety."
"Remarks: It’s not just people who can be delivered, but also other items.”
After seeing the last note, Rosen couldn’t help but take a breath.
This is simply a naked hint that he can deliver any items to the enemy's home thousands of miles away in the future.
This is definitely a powerful weapon that can easily kill enemies while sitting at home, without having to worry about having anything to do with you.
The level of delivery must be raised as soon as possible. Whether you can live as you like in other worlds in the future depends on its power. Rosen secretly made up his mind and immediately started leveling up frantically.
Note: This is how it was translated in the movie version I watched. I also saw some experts saying that it was the rocket fuel hydrazine n2h4.I really don’t understand what the body is, so just listen to it. Anyway, we are not growing potatoes on Mars, hehe.
