The tunneling expert's technique was indeed remarkable. When Hua Qingqing and Cheng Susu were struggling to accurately determine the digging direction without measuring tools, Han Wei arrived. After paying respects to his fellow wives, he waved his hand and immediately instructed his disciples to commence work. Under the thick night fog, everyone proceeded with utmost caution, as a single misstep might alert the patrolling Imperial Guards stationed outside. Fortunately, Zhao Fu's personal attendants hadn't dispersed; their presence significantly enhanced security through perimeter surveillance. Soon after, Han Wei resolved the issue that had left Hua Qingqing and Cheng Susu perplexed - he precisely mapped out an excavation route while confidently assuring no complications would arise.

Hua Qingqing sighed, "The power of collective effort is truly infinite. We Earthlings who've grown dependent on high-tech tools are rendered helpless here."

Cheng Susu laughed, "Still talking like that? I used to be a mapping expert myself but now..." Her voice trailed off as memories resurfaced, "It's like we're living through the tunnel warfare of the Anti-Japanese War era."

Hua Qingqing asked, "Did you recall something about your past?"

"Many things," Cheng Susu admitted. "Especially after Zhao Qian disappeared. I've remembered quite a few Earth memories. Truthfully, I wish I hadn't remembered too much - those painful recollections are unbearable. I regret not cherishing our time together when he was with me."

Hua Qingqing comforted her, "I have a feeling your husband will return soon. He certainly can't bear to be separated from his elder wife who's like an older sister to him. Remember how happy and excited he used to get cuddling in your arms?"
