The choice to temporarily hold back is not because Huang Dao is merciful, but because he sees his enemies as two groups: first, the Sword in Fish actors who want him dead and to destroy the Reincarnation Dream Flower; second, the mysterious underground tunnel. Although the underground tunnel appears in the Dark Forest due to Special Props, it does not mean he can safely leave after killing the Sword in Fish actors; he might be forever trapped in the tunnel or transferred to another world. Any result would destroy the original plan, and such outcomes are absolutely not permissible.
Among them, Li Shijiu's situation is the most unusual, and it is only now that he can confirm that Li Shijiu has indeed no connection with the Sword in Fish actors, at least not on any deep level. In other words, what Li Shijiu says and does are all based on her own experiences and thoughts, which means there's a high probability that everything she says is true.
