Among the three options given by the hacker, the second one seems better — it has better odds and a higher success rate. The only downside is it would impact innocent people...
As for the third option... it appears to be high risk, high reward, but in reality, it's all risk and no reward.
The blood lineage feeling brought by the Bloodline Mark can be controlled. If Nuke Arofa were really marked with a blood lineage, Xia Zhou could coerce him with a [Bloodline Curse] without revealing his own location or identity.
Or he could simply kill Nuke Arofa without making any use of him.
But with Nuke Arofa's vitality attribute value in the hundreds of thousands, it would take some time to kill him using the [Bloodline Curse].

Such a situation is too dangerous; Xia Zhou didn't want to see it happen.
