(2D) How to shoot multiple bullets in different directions

Hello everyone,

i was trying to create a different shooting "system", i basically used to do this by creating a for loop that iterate between all the bullets in a single shot, then based on the counter i add an amount to the current angle so i have a nice looking multiple bullets shot, i tried to do the same algorithm with unity and like always, the result is pretty fancy but not what i really want, i wrote this method to shoot bullets : private Transform myTransform;

     public GameObject   Bullet; // bullet prefab
 
 void shoot (float reload, int num, float distance)
 
     {
 
         tmpReload += 0.1f;
 
         if (tmpReload >= reload) {
 
             print (tmpReload);
 
             for (int i =0; i<num; i++) {
 
                 Quaternion target = Quaternion.Euler (i * distance, 0, 0); // this line is wrong, but i thought this is where i should do it
 
                 Bullet.transform.rotation = target;
 
                 Instantiate (Bullet, myTransform.position, Bullet.transform.rotation);
 
             }
 
             tmpReload = 0;
 
         }
 
     }

the result i want to achieve is a pretty basic for any 2D shooter game so i think the solution must be quite easy, PS : i tried to do this : Bullet.transform.rotation = Quaternion.Slerp (transform.rotation, target, Time.deltaTime * smooth);

but also i didn't have the result that i was looking for

thank you very much
