According to the original plan, after the two descended the mountain, Zhang Fan pressed the controller in his hand, and "Little Fatty" would be launched into the lava pool like a mortar shell.

As the "little fat guy" continued to sink in the magma pool, the "eggshell" continuously absorbed heat from the magma. After about an hour, the "eggshell" would reach the critical temperature and collapse, triggering nuclear fusion.

But now, the "little fat boy" has fallen down prematurely.

"We're doomed!" Katerina was on the verge of a breakdown. "How are we supposed to get down the mountain in an hour?"

“No, you’re wrong.” Zhang Fan placed the remote control in Katerina’s hand. “You see, we don’t have an hour.”

The screen on the remote control showed that the "eggshell" was expected to reach the critical temperature in 20 minutes and 15 seconds.

Damn it!

"Failed?" Katerina looked at Zhang Fan. "It seems we're all going to die here."

"Quick, take off your clothes!" Zhang Fan said.

"What are you trying to do?" Katerina stared, her eyes wide. "Do you want to have some fun in the last few seconds before you die?"

"What are you saying!" Zhang Fan said anxiously. "Quickly take off all accessories except the spacesuit, and get rid of the exoskeleton too! We don't have time, we have to be quick!"

"What are you doing?" Katerina looked bewildered, but she still obediently took off the extra equipment she was wearing, just as Zhang Fan had instructed.

"I suspect that kid Liao Changtian knew this was going to happen all along," Zhang Fan said through gritted teeth as he removed his equipment. "If I ever get back to Earth, the first thing I'll do is beat him up!"

"Is this also related to Mr. Liao?"

“Of course it’s relevant!” Zhang Fan said fiercely. “He gave me a suggestion, a suggestion that was supposedly for the sake of safety.”

"What suggestion?" Katerina asked, somewhat curious.

"A suggestion that would allow us to reach the foot of the mountain in 10 minutes."

"Impossible!" Katerina exclaimed. "There's no way we could get down the mountain in 10 minutes!"

“Yes, we’re not running.” Zhang Fan said as he crouched down and opened the airdrop crate. “We’re rolling down.”

“Get out…” Katerina’s eyes widened.

"Have you ever played with a zorbing ball?" Zhang Fan suddenly asked. "You know, those transparent big balloons where you crawl inside and can play on land or water."

"I played with this when I was a kid..."

"Let's play one more time now!"

Zhang Fan took out a plastic package from the box, opened the inflatable bag inside, and the plastic package quickly expanded into a large, double-layered, hollow, transparent balloon with a diameter of 3 meters.

"Go in quickly." Zhang Fan pointed to a trumpet-shaped entrance on the giant balloon.

The entrance is only big enough for one person to enter, but once inside, there is a spacious interior that can comfortably accommodate two people.

"Are you sure we can get down the mountain?" Katerina asked, still looking bewildered after entering the zorbing sphere.

“Liao Changtian said it’s okay.” Zhang Fan also crawled in. “The Zorbow is made of high-strength PVC material, which is very tough and not easily punctured. The Apollo spacecraft is located at the lowest point in the center of the crater basin. As long as we roll into the crater, gravity will bring us to the Apollo spacecraft. The slope of Mount Olympus is very gentle, so we won’t roll too fast, and we can still control the direction with a little effort.”

"See, isn't this simple?" Zhang Fan recalled Liao Changtian's serious face when he said those words, and gritted his teeth in hatred.

"How can I try?" Katerina stared in astonishment the whole time.

"Like this," Zhang Fan said, then shoved himself to the side. "Go!"

The zorbing ball lost its balance and began to roll down the mountain.

"Wow—" Katerina screamed in fright.

"Don't panic!" Zhang Fan hugged Katerina tightly. "We still need to control the direction of the roll."

"How do I control it?" After rolling it a few times, Katerina got used to it, but she could no longer distinguish up from down from left from right.

"See that crater? If you do, just smash it in there."

The two people rolled around inside the ball, which bounced and rolled downwards.

Many people have played with zorbing, where you crawl inside a zorbing ball and roll down a grassy slope; it's a lot of fun.

But probably no one has had a more thrilling experience than the two of them, because you can't find a higher hill in the solar system.

The zorbing ball landed precisely in the crater below, bounced a few times, began to roll towards the lower center, and then slowly came to a stop.

After Katerina emerged from the zorbing ball, she knelt on the ground, feeling nauseous. She felt as if the whole world was spinning.

"Get up!" Zhang Fan pulled Katerina up and they ran. They were still some distance from the Apollo spacecraft.

Upon boarding the cockpit of the Apollo spacecraft, a short but violent tremor came from underground, and the entire Mount Olympus seemed to shudder.

Mount Olympus visibly expanded for a moment, then rapidly contracted.

The two people in the cockpit were terrified by the scene outside the porthole. They immediately started the spaceship and flew forward at maximum speed in the opposite direction of Mount Olympus, without even glancing back.

Zhang Fan and Katerina felt as if someone had suddenly pushed them from behind, and the spaceship almost went out of control. Then, huge plumes of smoke began to envelop everything around them, completely blocking their view ahead.

Fortunately, the Apollo spacecraft used hydrogen-oxygen engines, so there was no problem of the engine stopping due to inhaling dust. As long as it didn't collide with anything, it could keep flying forward.

Fire dragons appeared in the thick smoke; they were lava fragments thrown into the air.

This must be a sight only found in hell!

According to Liao Changtian, the volcanic ash from the Olympus eruption covered an area of ​​up to 1,600 kilometers, turning a 1,000-kilometer radius completely black for a week. If it weren't for the subsequent rain, this would have lasted even longer.

The upper part of Mount Olympus was stripped away by 4,250 meters, which is almost half of Mount Everest. The lost mountain body is about 100 cubic kilometers, weighing 23 billion tons, and the total volume of the ejecta is 4,517 cubic kilometers.

The volcanic eruption caused the average temperature of the Martian atmosphere to rise sharply by 5°C in a short period of time. After the volcano stopped erupting, a new crater was formed on Olympus Mons, which was meters in diameter and 1,700 meters deep.

Zhang Fan and Katerina, like two mischievous children, slunk away to the south pole of Mars.

The Martian south pole is now a world of ice and fire, filled with boiling water vapor.

"How can we fly like this?" The spaceship pilot had been changed to Katerina. Outside the porthole, all that could be seen was a white mist of water vapor, and visibility was zero.

"Don't look out the window! Look at the radar! That red dot is where Ivanka is!" Zhang Fan shouted. "We're in the hottest region on Mars right now. Just imagine you're flying over a giant boiling cauldron!"

The scorching magma has already surged beneath the ice cap, and the entire Martian south pole is rapidly heating up. Under extremely low atmospheric pressure, much of the solid ice has already vaporized into water vapor before it can even melt into water.

The atmospheric temperature here is 30°C, making Mars' south pole the hottest region at this moment.

Zhang Fan had already moved to the cargo hold of "Apollo," fastened a seatbelt to himself, and was preparing to jump out after the spacecraft hovered.
