Lilith won't be responsible for anyone other than Zheng Yichen, so even if Lilith manages the Hazy City defense line well, if something happens to Zheng Yichen, Lilith won't be 'responsible' for this defense line.
Even if this defense line is operated to the point where it almost defeats the Boundary Breaking Organization, she would still choose the most decisive action between achieving success and rescuing Zheng Yichen.
If abandoning the Hazy City defense line and using all its resources could exchange for one opportunity, she would unhesitatingly abandon the Hazy City defense line to exchange for that one opportunity.
If she's not allowed to abandon it, only after calculating everything and confirming that there's not a slightest possibility, would she continue to fulfill Zheng Yichen's 'last wishes'.
Zheng Yichen undoubtedly does not want to die, but if one day he really has to perish, it should be thorough.
