Letting the Tyrannosaurus saunter over like this is probably also due to the instructions from the controller behind them.
This group of Tyrannosaurus might possess explosive speed for rapid movement, but they can't sustain it for long; even the blood-striped Tyrannosaurus likely can't avoid this issue.
It's somewhat similar to Mimi.
So, at this moment, they are obviously conserving energy.
However, by letting Xu Xin and the others see the tracks of the Tyrannosaurus so clearly, they are actually providing them with preparation time, exposing the arrogance of this controller.
Clearly, the other side looks down on this side.
The other side probably thinks that even if they give them time to prepare, they would be helpless, and it's better to let the dinosaurs conserve energy and exert force only when they reach Crystal City to ensure success.
It can only be said...
Their approach is indeed very reasonable.
