Don't look at Vuong Han's calculation ability now, but in fact he has been locked in this realm for hundreds of millions of years. Of course he knows this, but sometimes saying it is useless. Now he just observes the phenomenon first and confirms that this phenomenon will actually happen, then he will deduce the reason behind this known correct answer, just like this Tu Hai, the reason Vuong Han will find out Tu Hai, because he has seen Tu Hai Tu Hai really exists like that, so he is sure that the other party must have a reason, so Tu Hai can be said to be a " authoritative belief", for Wang Han, it was Tu Hai's "Existence" that supported him during his subsequent long research. ,The bow and arrow are already in his hand, the arrows are also prepared, as long as something appears at this time, he can immediately apply measures to see if he can replace the opponent or control the opponent's movements. or not.
