In the evening, the two arrived at their first rest stop.

The airdrop package contained food and water, as well as replaceable lithium deuteride batteries. The two helped each other remove the exoskeleton, set the "little fat guy" aside, connected the water bag to the spacesuit's valve, opened the valve, and sucked out the liquid food inside.

The place to sleep is a "capsule apartment". Although it is not very useful as a shelter, at least there is an air bed to sleep on, so that you won't fall on the ground all night and be sore all over the next day.

"Fan, how many times have we slept in the same bed?"

"No, please don't say that." Zhang Fan was startled and quickly corrected Katerina. "We're both wearing spacesuits right now! Technically speaking, we're completely physically isolated from each other."

"Tch, don't let your seemingly upright appearance fool you, you're anything but honest at heart." Katerina nudged Zhang Fan with her body.

"What did I do wrong?" Zhang Fan protested, shoving back.

“Never behaves properly!” Katerina shoved back, saying dismissively, “Remember that night on the fireflies? I was asleep, but my body was anything but still.”

"What did you do to me while I was asleep?"

“I didn’t do anything,” Katerina nudged him again and laughed. “I just wanted to make sure you behaved yourself where you were being naughty.”

"You, you, you, don't scare me!" Zhang Fan sat up in fright.

“Hahaha.” Katerina laughed. “It’s alright, I didn’t do anything. You weren’t qualified back then. Hehe.”

Zhang Fan breathed a sigh of relief and lay back down. Thankfully, nothing happened. What if something had happened and he hadn't even felt a thing? That would have been a huge loss!

"As expected, young boys are inexperienced; they blush at the slightest touch." Katerina giggled happily. "I'm saying, you and your little sweetheart have been together for so long, and nothing's happened? Are you impotent?"

"You're the one who can't!" How could a man be told he can't by a woman? Zhang Fan's tone hardened as well, "You didn't see it, how do you know it didn't exist!"

"Bullshit." Katerina gave Zhang Fan a disdainful look. "He's definitely an inexperienced young man, isn't he? I can tell just by looking at the way he walks."

"Ah, this..." Zhang Fan was sweating profusely and quickly changed the subject, "How about we talk about you? With your qualities, I don't believe you don't have suitors around you."

“What’s the use?” Katerina stopped laughing and sighed softly. “No matter what it is, once it gets involved in politics, it becomes dirty…”

"You mean...something like a political marriage?"

"Why should women be treated as appendages?" Katerina's tone turned angry. "Why should women be reduced to a political bargaining chip for men?"

“Sigh…” Zhang Fan also sighed, “I understand Prime Minister Medvedev’s difficulties. Your Ross’s ‘two-person show’ style of power transfer has been going on for many years, hasn’t it?”

"Leaders change frequently, but each term inevitably involves shifting from one hand to the other. To eliminate doubts on both sides, political marriage is certainly a good way to build mutual trust."

“So I envy Ivanka,” Katerina said. “At least she can do whatever she wants without considering the consequences, which is something I can’t do.”

“No wonder Ivanka said you and she are similar in status, and she understands many of the things you’ve done.” Zhang Fan looked at the night sky above the transparent window and said, “Blue Star has already gone through all this, what does politics matter? If you can go back in the future, then you have to be tough this time and do what you want to do!”

“Okay!” Katerina nodded. “If I can go back to Earth in the future, the first thing I’ll do is find someone I like and get married.”

“Okay, I support you!” Zhang Fan nodded as well.

"What if the other party is unwilling?"

"With a beauty like Kada's qualifications, how dare the other party be picky? If that's the case, then I'll help you throw 'Little Fatty' into his house!" As a friend on the same side, Zhang Fan expressed his firm support.

"It's a deal!" Katerina suddenly sat up, staring at Zhang Fan. "You'd better not be too scared then!"

"What wouldn't a real man dare to do?"

Zhang Fan didn't care who the other party was; he definitely couldn't back down when the time came.

The next day, the two continued their journey. The higher they climbed, the steeper the slope became, and their pace had to slow down. There were also many large craters on the ground caused by ejected volcanic rocks, which they had to carefully avoid, as falling into one would be troublesome.

On the third day, lava flows began to appear on the ground, originating from the crater. Some of these lava flows appeared to have cooled and solidified, but if you were to accidentally step on them, the thin shell concealed a pool of bright red lava, which could instantly destroy your leg. This was why the Apollo spacecraft could not be forced to land on the mountain; the hidden risks were too great.

On the fourth day, the two were able to see the summit of Mount Olympus.

This must be the first time in human history that the summit of Olympus Mons has been seen from the surface of Mars. The mountain is so tall and so large that if you were standing on flat ground, the summit would be hidden beyond the horizon.

A Boeing 797 flying at an altitude of meters on Earth can only reach halfway up a mountain.

Mount Olympus is like a child who is sleeping soundly and cannot be woken up; if you anger him, the consequences will be unimaginable.

Although in a period of dormancy following the eruption, volcanic ash still surged out from the fissures in the mountain's belly, forming a huge column of smoke that reached into the sky.

Zhang Fan and Katerina stood on a high point on a small ridge, with a flowing lava stream in front of them.

"Fan, what should we do?" Katerina looked up and saw that the lava was flowing out of a gap in the volcano. Looking down, she estimated that it would take about 10 miles to bypass the lava flow.

But the mountaintop was just across the way, less than 30 meters away, blocked by this valley stream. Time could be disregarded for the time being, but the problem was that there were no airdropped supplies on the detour route.

"Have you ever played on a swing?" Zhang Fan suddenly asked.

"I played with this when I was a kid, what do you want with it?"

Zhang Fan laughed: "Let's play one more time."

"Hold on tight!" Without saying a word, Zhang Fan turned the exoskeleton to its maximum power, picked up Katerina, and ran.

"What are you going to do? Wow—"

Zhang Fan took a running start to the edge of the valley, jumped into the air, pulled the safety buckle, and below was bright red lava. The metal cone at his waist shot out and nailed into the opposite mountain.

The two men crashed into the opposite rock wall, their feet now only a few meters away from the lava flow below.

Zhang Fan bent his knees and spread his legs in advance, and the exoskeleton effectively cushioned and absorbed most of the impact force.

"Hey, could you at least tell me beforehand next time?" Katerina was still a little shaken as the two of them climbed up the rope.

"No problem, it's your turn to jump next time."

After reaching the summit, the two climbed down into the crater and, in a relatively flat area, began installing "Little Fatty".

"Little Fatty" is the result of Zhang Fan and Katerina's joint efforts.

A new type of nuclear fusion bomb based on helium-3 extracted from minerals.
