Forced to marry a disabled man in the countryside? I'll repay you tenfold!

He secretly clicked his tongue in amazement: He had long heard that Captain Zhou had married a particularly capable and beautiful wife, but he never expected that she would bring so much delicious food with her on her long trip!

"Here, Comrade Liu, you must be tired from driving. Have something to eat." Su Wanqing handed over a cantaloupe and fried fish.

"No, no, no, Dr. Su, I can't accept this..." Xiao Liu blushed and quickly declined.

"Take this. You'll need the energy to drive and get there faster." Su Wanqing stuffed it into his hand without saying a word. "Don't be shy, consider it a treat from family members to the frontline soldiers."

Unable to resist, and genuinely tempted by the food, Xiao Liu thanked him and began to eat in small bites. After a few bites, his reserve dissipated considerably, and he gradually opened up and started talking.

"Dr. Su, are you really Captain Zhou's wife?" He still found it hard to believe.

"Genuine, no doubt about it." Su Wanqing took a piece of cantaloupe and ate it herself. "Otherwise, why would I be in such a hurry to get there?"

"That's not what I meant," Xiao Liu said, scratching his head sheepishly. "It's just that Captain Zhou is notoriously strict and stern around here. During training, just one glance from him and our legs go weak. We can't even imagine what he's like at home. Is he just as authoritative?"

"You're mistaken. At home, he's completely different from what you see. He eagerly does housework, can do everything and is good at it all. He doesn't talk much, but he's thoughtful and especially considerate of his family's feelings..." Su Wanqing said with a smile.

Zhou Yanshen: Wife, can you compare to these brats?

Even Zhou Yanshen himself didn't know why, but when he saw his wife, his voice subconsciously became gentle.

Over here, Xiao Liu was dumbfounded, his mouth agape, wondering if the person Dr. Su was talking about was the same cold-faced captain he knew. That Zhou Yanwang, who could take on several veterans single-handedly and was so ruthless during training that it made people want to cry, was actually a virtuous husband at home?

As the conversation deepened, the ease on Xiao Liu's face slowly faded, replaced by a serious expression. He hesitated for a moment, but decided to give Su Wanqing a heads-up beforehand, lest her expectations be too high and her disappointment be even greater.

"Dr. Su, there are some things I feel you should know. That karst region is enormous. Down from the entrance where they disappeared, there are dozens of main waterway branches that have already been explored, not to mention the hidden crevices and shafts. With the current manpower, searching each waterway one by one... conservatively speaking, it would take at least ten days to two weeks. You... need to be mentally prepared."

"Furthermore, the five comrades who initially went down to search also lost contact for a time. Therefore, the higher-ups have ordered a large-scale underwater search to prevent further losses, which is making the search very slow." In the end, they might only find bloated corpses—

He couldn't bear to see his sister-in-law, who had always been optimistic and strong, break down when faced with a long, hopeless wait and potentially worse news.

Su Wanqing listened quietly, quickly analyzing the information. The underground network was like a maze, but it also meant that her "cheat code" might have unexpected uses.

Following Xiao Liu's words, she looked anxious and confused: "Why would they risk going down into such a complicated underground river? Are they on some special mission? What are they looking for?"

She needs to know more background information to determine Zhou Yanshen and his group's possible operational logic and where they are trapped.

Xiao Liu hesitated for a moment. Logically, this was a classified mission. But looking at Su Wanqing's concerned eyes, and remembering that she was Captain Zhou's family member and had some geological knowledge, perhaps she could offer some insights?

"We are indeed searching for a special geological sample. It has important reference value for national defense scientific research. The mission requires us to go deep into certain specific layers of the underground river system for surveying and sampling. Captain Zhou and his team went down with this mission."

Su Wanqing's heart skipped a beat! Special minerals? Geological structures? This was exactly what her Insightful Grid function was all about! Not only could it scan living beings, but it could also sense special minerals or energy fluctuations! If Zhou Yanshen and the others' mission target was a mineral with significant energy characteristics or rarity, then using the Insightful Grid, she might not only be able to find people, but also directly locate the mission target area, greatly narrowing down the search area!

A barely perceptible glint flashed in her eyes. "So that's how it is. That place must be really hard to find."

"It's not just hard to find, it's like looking for a needle in a haystack," Xiao Liu sighed. "Hopefully, Captain Zhou and the others will be lucky..."

It was already late at night when we arrived at our destination.

Here, right at the foot of the mountain, more than a dozen military tents and some temporary prefabricated houses have been set up.

"Dr. Su, we've arrived. This is the temporary command post and rescue camp." Xiao Liu jumped out of the car and pointed to one of the smaller tents. "It's too late tonight, let me take you to rest first, and I'll take you to the command post to report tomorrow morning."

Su Wanqing nodded, and Xiao Liu left after escorting her to the tent. She climbed into the military tent with her package and medical kit. Although there were no blankets, she took out a set of blankets from her spatial storage and laid them out before forcing herself to fall asleep amidst the distant sounds of machinery and people moving around.

The next morning, Xiao Liu arrived promptly and knocked on the tent flap. "Dr. Su, are you awake? I'll take you to see Commander Zhao, the overall commander of this rescue operation."

Soon, Su Wanqing was led to a large command tent in the center of the camp, where a meeting seemed to be taking place. Xiao Liu stood at attention at the entrance and reported, "Report!"

"Come in," a deep, slightly hoarse voice said.

Xiao Liu led Su Wanqing inside. The tent was dimly lit, with a makeshift long table in the center. Five or six people sat around the table, some in military uniforms, others in civilian clothes, appearing to be middle-aged technicians. At the head of the table sat a soldier around fifty years old with a furrowed brow, presumably Commander Zhao.

When he saw that Xiao Liu had brought in a strange woman, Commander Zhao glanced at her, his eyes filled with obvious doubt and impatience.

Xiao Liu quickly stood at attention again. "Reporting, Commander, this is Comrade Su Wanqing, Captain Zhou Yanshen's wife. She is—"

Before he could finish speaking, Commander Zhao's face darkened. "Nonsense, Xiao Liu! I told you to notify the families and comfort them! Who told you to bring their families directly to the front-line command post? Do you know what the situation is here? They're just making things worse!"

Xiao Liu shrank back, looking aggrieved, after being yelled at.

Su Wanqing stepped forward and handed over the letter of introduction written by Liu Shuqing. "Commander Zhao, hello. I understand your concerns. But I am not just Zhou Yanshen's family member. I am also a doctor who has treated battlefield first aid and various complex injuries; I also have considerable knowledge of geological structures and mineralogical identification; I believe that, given the current manpower shortage, I can provide not only medical support and situation analysis but also some assistance on the front lines. This is my letter of introduction and organizational certificate."
