Irene had such an identity and background, which really surprised Nathan.
Moreover, Irene also revealed that the Nums' forces could not be wiped out under the deterrence of such a powerful military force in Nievic, in fact, it was also because of Mikhail's earlier layout.
Irene's wise grandfather had already known the disadvantages and loopholes behind the overall environment of Nievic.
This made Nathan stunned. Since it was Mikhail's arrangement, why did Irene reveal it to him? Wouldn't this let the plan that Nievic had for years fail?
This plan could change the whole Nievic. Once it succeeded, the oligarchs would be wiped out by the mayor who ascended to the presidency.
In the end, Irene gave an answer that Nathan could easily accept. She did this to save her life.
It was reasonable for humans to struggle for life.
