The "Beetle" broke through 300 meters of ice and reached underwater again.

Although she was mentally prepared, Ivanka was still taken aback by the scene before her when she first arrived here.

This place looks exactly like the South Pole of Earth. Wherever the lights are visible, there are "whales" blowing bubbles as they swim up and down.

Ivanka activated the thermal imager and quickly located the gap in the magma chamber. She turned the Beetle around and drove upwards, wanting to give it a try.

Upon reaching the ice layer above, Ivanka turned the "Beetle" around, activated all propellers, and dove downwards at maximum speed.

As the "Beetle" swooped down to the limit of the steel cable, Ivanka pressed the bomb release button, and the "depth charge" sank at an even faster speed than before, relying on inertia and gravity.

boom--

The thermal imager shows that the "depth charge" precisely hit the gap in the magma chamber, causing the surrounding temperature to drop rapidly and forming a localized area below 0°C.

However, the adhesion of this local area is too poor. According to the thermal imager, this area is being slowly pushed away by the magma jet until it floats to the surface.

It still doesn't work, huh?

Ivanka slumped dejectedly onto the dashboard of the Beetle.

"Ivanka, Ivanka?" Zhang Fan's voice came through the communicator.

"I am here."

"Did it fail?" Although he couldn't see what was happening underwater, Zhang Fan could guess what was going on from the voice in the communicator.

“It failed.” Ivanka’s voice was full of dejection.

"Then come up first, and we'll think of other solutions." Zhang Fan wanted to comfort Ivanka, after all, she had already done her best.

On the screen of the Apollo spacecraft, there was a small dot; that was Ivanka's location beneath the ice. Apollo did not have underwater detection capabilities; the small dot indicated the location of a communication signal source.

"Fan, I won't go back. You go back first."

Ivanka's emotionless voice came through the communicator.

"Not going back? What do you mean by that?" Zhang Fan suddenly felt a tightness in his chest and his palms started sweating. He had a premonition that things were developing in a way that was beyond his expectations.

"Get up here right now! Don't forget you're still a criminal!" Zhang Fan spoke almost in a commanding and threatening tone. "We've already dropped all three 'depth charges,' what are you going to do hiding down there?"

“No, you’re wrong,” Ivanka’s voice came through the communicator. “There’s one more.”

...

Qiongzhou Island, Wenchang Temporary Center.

The 10th International Multilateral Symposium on Mars Rescue is still underway.

"Do you think Ivanka will implement 'Plan B'?" Director Xiao Yimin asked, looking at the crowd around him.

“She definitely will!” Chief Engineer Yang Jiandong blurted out.

"Hmm? Teacher, you seem to know her very well?"

"Sigh..." Yang Jiandong sighed, "I once had a relationship with that girl."

"Oh?" Xiao Yimin immediately became interested. "How come I've never heard you mention this before, teacher?"

“That was 20 years ago.” Yang Jiandong looked up, lost in memories. “Back then, Ivanka’s grandfather, Nick Washington, was the President of the United States. President Nick sent his most beloved granddaughter to China to study Chinese culture. The Premier personally made the arrangements and gave instructions for this. My family was fortunate enough to be selected as the host family for Ivanka during her studies in China.”

"Ivanka lives at your house, teacher?" Xiao Yimin was stunned.

“This was President Nick’s request,” Yang Jiandong said. “The president said that the boy was quite smart, but stubborn, and sometimes showed some very dangerous ideas. Such a boy would have a hard life in the future.”

"President Nick did not expect her to achieve great things in the future; he only hoped that she could grow up happily like a girl from an ordinary family. The president believed that the influence of traditional Chinese culture would greatly cultivate her character, so he arranged for her to come to China to study."

"President Nick specifically instructed that Ivanka's food and lodging expenses be covered by the U.S. Embassy, ​​and that she should not be given any special treatment. She should walk to and from school like any other child, and should not be picked up or dropped off by car. She can take the bus when she goes out, but she should pay for it."

“Ivanka was only seven or eight years old at the time, but from the first moment I saw her, I knew that this little girl was extraordinary.”

“Her eyes were full of intelligence, and she had a unique quality that other children her age didn’t have. At the government school she was attending, she already showed the qualities of a leader and became the school’s leader.” Yang Jiandong laughed at this point. “To put it bluntly, she was a ‘king of the kids’ and a ‘troublemaker.’ During the two years she studied in China, she got a lot of beatings from me for this.”

“Mr. Yang, you still dare to hit her?” The European Space Agency Director, Brosnan, was also intrigued. “You know, this is the future ‘First Daughter’.”

“What’s there to be afraid of? You have to be punished for what you do wrong!” Yang Jiandong said, waving his hands in the air a few times. “The ruler I used to hit her was left by President Nick. It’s only right for a grandfather to discipline his grandson!”

"And then what?"

"After President Nick left office, relations between our countries deteriorated rapidly, as you all know. Ivanka returned home a year later, and I haven't had any contact with her since."

Everyone fell silent after hearing this.

"So, teacher, you think she'll definitely go with Plan B?"

“Definitely! Sigh…” Yang Jiandong sighed again. “This girl’s personality has never changed since she was a child. She’s smart, competitive, and has a very strong sense of self-respect. Once she’s made up her mind, no one can stop her. Even if others don’t understand or misunderstand her, she won’t explain herself to anyone. That’s why she’s been punished by me a lot since she was little. Sometimes, even when someone else is clearly in the wrong, she won’t explain anything to me, even if she’s going to get punished by me.”

...

"Ivanka, would you like to come up first?" Zhang Fan's tone had softened.

“Fan, I can finally speak to you properly now. Hehehe—” Ivanka’s happy laughter came through the communicator.

Zhang Fan stared helplessly at the Apollo screen, watching a small dot rapidly move downwards. Judging from the intervals on the screen, the dot had already traveled more than 1,000 meters.

The "Beetle" discarded the steel cable attached to its rear and ventured alone into the dark, deep waters.

“There’s no point in you doing this…” Zhang Fan said, almost pleadingly.

“It makes sense! Of course it makes sense!” Ivanka’s voice came through the communicator, along with the creaking sound of metal being compressed by high water pressure.

"Fan, when the whole world was thinking about why I didn't just die, you were the only one who still cared about me."

"so……"

"I don't want you to die."

"You saved the whole world, and I saved you."

"That way I'm even with them."

"Right?"

In the icy blue water, a lone beetle crawls toward its own rose...

...

Option B:

I. The diameter of the magma chamber opening beneath the Martian south polar ice cap is estimated to be between 5 and 6 meters, and the underground magma temperature is estimated to be between 1000 and 2500 degrees Celsius.

Second, the "Beetle" Mars rover is about 6.5 meters wide, with a maximum width of 7 meters, and its titanium alloy drill bit can withstand a high temperature of 3,000 degrees Celsius.

Third, the "Beetle" vehicle body can be used to seal the gap in the magma chamber. Because the magma lacks fluidity after being sealed, the magma in the "straw" will gradually cool and harden, eventually turning into solid magma rock.

Fourth, the Beetle's body cannot withstand the water pressure of 3,000 meters for an extended period of time. Except for the most robust spherical occupant compartment, the rest of the structure will be gradually destroyed by water pressure exceeding 10,000 tons per square meter.

Fifth, due to the loss of heat supply from the magma chamber, the Martian south polar ice cap will gradually return to its original state.

VI. The Beetle's crew capsule, having lost its power and energy, will be permanently sealed 3,000 meters below the ice layer.

This concludes the entire "Nuwa Mending the Sky" plan.
