The local time of Europa was already a little late, but the conversion to earth time was just right. A group of people poured into the restaurant and divided up to eat and order food. Ye Han took his share and greeted Luo Qi, and sat down at a table with the mechanical expert Fang Yan.
Part 1. (PS: Book friend Crimson Crescent Moon makes a guest appearance - this is not counted in the word count.)
Putting a mouthful of rice into his mouth and chewing it twice, Ye Han raised his eyelids and glanced at Fang Yan. Seeing that Fang Yan had no intention of speaking, he could only lower his head and continue to deal with the food on the plate.
Luo Qi took a mouthful of rice and stuffed two chopsticks with shredded pork and stir-fried leeks. It tasted delicious when chewed.
Ye Han couldn't help but advise: "Slow down, no one will take it from you, there's still more left."
He wanted to ask about the mission immediately, but after thinking about it, he held back and waited until he was almost done eating.
Luo Qi chuckled but couldn't speak at all.
When the base was first built, everyone's non-staple food was space food shipped from Beiyue Continent. It was okay to eat it once in a while, but everyone would get tired of eating it three times a day.
However, the base has a special planting cabin, which uses the multi-layer soilless cultivation method to grow vegetables based on Beiyuezhou's experience.
When the convoy set off, the vegetables in the planting cabin had just sprouted. Unexpectedly, within ten days, the first batch of fast-growing vegetables had already been served on the dining table. It was not far away to achieve full self-sufficiency in vegetables.
Fang Yan commented while eating: "This planting cabin really solves a big problem. You can eat fresh vegetables here, which is great!"
Luo Qi finally swallowed what was in his mouth and said with a smile: "I heard that Beiyuezhou has also developed a breeding cabin. Why hasn't it been equipped for us?"
Fang Yan said with a smile: "Well, raising chickens can't lay eggs, raising pigs can't give birth to babies, so it's okay to raise fish. Anything else is just nonsense."
"Why?" Luo Qi asked curiously.
"It seems to be due to weightlessness... Hey, the gravity here is okay. You can try it if you don't want to." Speaking in dialect, he cast his hopeful eyes on Ye Han, "But that thing uses frozen embryos, and the breeding cycle is not short."
"You can give it a try." Ye Han said, "We're not sure how long we'll have to stay here."
Luo Qi's eyes widened: "Vegetable seeds are sent to the planting cabin, and frozen embryos are used to the breeding cabin. Good guy, it's quite economical."
Even today, when the cost of aerospace has been greatly reduced, aerospace is still a money-burning business. Bei Yuezhou must be doing this to reduce costs.
"Have you eaten yet?" Ye Han glanced sideways at Luo Qi.
Luo Qi nodded: "That's almost it."
"Okay." Ye Han put down his chopsticks, "What's going on?"
Although there are people coming and going in the cafeteria, we are all our own people in the base, so there is no need to worry about leaking secrets.
Luo Qi didn't say anything, his first reaction was to look at the dialect.
Fang Yan scolded dissatisfiedly: "Look at what I'm doing. Just say whatever you want."
"That's what you said!" Luo Qi passed the responsibility completely, and then looked at Ye Han and said, "Boss, our Professor Fang said that if we want to study planetary engines, we must build a new one underground.
base!"
Ye Han was confused: "What does this all mean? Let's start from the beginning."
"Oh!" Luo Qi agreed, recalling what he had experienced these days, and casually picked up his chopsticks and tapped them on the table, "This is our base. This is the entrance to the underground passage. After entering, there is a slope passage, all the way from here.
You can go down to the center of the earth, and there is a branch road every other way. I saw aliens in the branch road, and there must be an underground city inside."
Fang Yan said: "I have carefully observed that the closer to the ground, the more aliens there are. Not a single alien can be seen in the forks close to the center of the earth. There are also many forks that are simply dead ends. I don't know if the passages have collapsed.
Or deliberately sealed it." At this point, Dialect paused, "From the ground to the center of the earth, there are underground cities everywhere. I don't know how many forked roads there are on this road. This is just a passage. I have been thinking about it these days.
I wonder how many people can live in Europa if it’s full.”
Ye Han said: "The political work team obtained some information from aliens. According to the information, Europa has never been full."
"What else is there?" Fang Yan widened his eyes in surprise, "What else? What else?"
Ye Han nodded: "It's the same thing as a history book. I don't know if it is true yet."
"Then find a way to prove it, use carbon 14 measurement, or some other method." Fang Yan quickly came up with an idea.
Ye Han smiled bitterly: "It's just a few oral messages, how do you measure it?"
Fang Yan's eager expression suddenly froze, and he took a mouthful of rice in disappointment.
Ye Han looked at Luo Qi: "What's the condition of the passage? How long and wide is it?"
Luo Qi quickly replied: "It's basically a perfect circle, very straight, with a diameter of no less than ten meters, and a very steep slope, almost 60 degrees. Our car almost turned over when we drove in."
Ye Han frowned: "Then why didn't you report it?"
The two engineering vehicles at the base are modified armored vehicles. They can climb a slope of up to 35 degrees. Jupiter's zero gravity is lower than that of the earth. The climbing angle can be slightly increased, but the maximum cannot exceed 42 degrees. Otherwise, the engineering vehicles
The center of gravity will cross the support point of the rear wheel, and the car will definitely roll over.
Weighting the chassis to shift the center of gravity, or installing auxiliary wheels can improve the gradeability, but the several methods he could think of required technical and equipment support, which was simply not possible on Europa.
"It wasn't that steep at the beginning, and we lost contact before we reached the steep place." Luo Qi explained.
"Then how did you get down?" Ye Han asked in shock.
Luo Qi grinned and made a dragging gesture with his hands: "The aliens sent two bugs to bite the tail of the car, and they kept going down."
"Drag it all the way to the center of the earth?" Ye Han asked in disbelief.
"No, I changed it a few times in the middle, and the gravity got lower the further down I went. At the end I was almost weightless, and I could pull the car away with one hand." Luo Qi said.
Fang Yan added: "If the gravity were not so low, we would not dare to say that the planetary engine is in the center of the earth."
"Oh!" Ye Han suddenly realized, "How many turns does that passage have?"
The planetary engine is in the center of the earth, so the channel leading directly to the engine must be perpendicular to the horizontal plane. Since the inclination of the channel is 60 degrees, the channel must not lead directly to the center of the earth.
"Ten trips back and forth, and I also went into the dungeon a few times in between," Luo Qi said.
Ye Han's frown deepened: "Luo Qi, from your perspective, what can we use to fly directly to the center of the earth? Individual aircraft? Rotorcraft? Helicopters? Or fighter jets!"
Luo Qi thought for a while and said: "Fixed wings are definitely not possible, and rotary-wing aircraft are also a bit difficult. Armed helicopters should be fine, but they can only be lined up in a row and fly one by one."
Fang Yan was stunned when he heard this, and couldn't help but ask: "Director Ye, do you mean... a sneak attack?"
