Though Zhou Tian had substantial strength to stop him at that time, if that Tyrannosaurus clearly knew what it wanted to do, it would indeed be somewhat difficult.
However, although Zhou Tian's strength was exceedingly powerful and his entanglement made it nearly impossible for that Tyrannosaurus to escape, nothing is absolute. To say that the Tyrannosaurus had no chance of escape at all would not be correct.
In fact, while hope was slim, if that Tyrannosaurus truly wanted to escape, it indeed was not entirely hopeless at that moment.
Relying on the Tyrannosaurus's Wind System Rule ability, an escape would naturally seem impossible. But, that Tyrannosaurus also had cultivated another rule ability, and from its performance at the time, it was evident that this hidden ability was best at crowd control.
