Having previously performed the technique, it was easier to repeat it now. Urahara gathers and compresses a great amount of keigoku behind the portal, shaping it into a bolt of force lightning. Before opening the portal, he paused a bit to try and figure out how he would take control of the keigoku and reform it after having released it.
When ready, he opened a portal in front of him which allowed the bolt of force lightning to get released at great speed while also loosing a bit of its compression. Urahara took advantage of this, now it was easier for him to take control of the keigoku. Without wasting any time, he "tamed" the keigoku with his own chakra, allowing the bolt to separate much faster until it was only a large amount of senbon sized needles which still continued straight forward.
It was now possible to direct the keigoku as it was split into these senbons, keeping control over it, Urahara manipulates them to rotate 45 degrees to the left from their original trajectory.
