Zhang Feng's current constitution of 'Brain and Heart' is at 9, and his spiritual sense already covers over forty meters.
Adding to this is Yu God's occasional intimidation.
This keeps Zhang Feng constantly in a state of heightened spiritual awareness.
It is precisely this awareness.
That allowed Zhang Feng to notice something off about these four inspectors.
Because their constitution, on average, is around 150.
And no matter how much they tried to disguise it while walking, he could see their internal muscle exertions through their clothes and skin.
Such deliberate concealment and clearly specially trained techniques of exertion.
In an instant, Zhang Feng knew these four were assassins, especially since their murderous intent was locked near him.
The reason they hadn't locked onto him was that they hadn't captured anything 'specific' about him yet.
Because they didn't know who he was at first, or even if they did, their intent was not accurately murderous.
