* It limited the territorial extent of the empire. The soldiers' refusal to advance beyond a certain point meant that the empire could not expand as far as it might have otherwise. This limited the empire's access to resources and made it more vulnerable to attack from neighboring states.
* It created discontent among the soldiers. The soldiers who were forced to remain in Central Asia were unhappy with their situation. They felt that they were being treated unfairly and that their lives were being put at risk for no good reason. This discontent led to a decline in morale and made it more difficult to maintain discipline within the army.
* It weakened the empire's military strength. The empire's military strength was dependent on the willingness of its soldiers to fight. The refusal of the soldiers to go deep into Central Asia meant that the empire had fewer troops available to defend its borders and to conquer new territories. This made the empire more vulnerable to attack from its enemies.
In conclusion, the refusal of soldiers to go deep into Central Asia had a significant impact on the effort to build a great empire. It limited the territorial extent of the empire, created discontent among the soldiers, and weakened the empire's military strength.
