Shi Lang did not know anything that was going on back at the command ship, his complete focus was dedicated to the fight in front of him. He was aware that his ability had a limit. After a certain point, his body movement will not be able to keep up with the senses.
So, for him the spirit energy was like a boon, it enhanced his physical body limits, and made him strong. He was dodging the phaser beams shot by the first prince at a very close range, it was as if he was a ghost. His speed had begun to leave quasi after images.
The first prince was getting enraged with every single second his attacks were useless. Shi Lang, on the other hand, was getting calmer with every single second. His aura was as if a sword of ice. Suddenly, the phaser gun glitched. Not everyone could detect a fractional difference in the firing time. This was because the core inside the gun has been over used and was exerting and it will take a longer time for the core to charge and attack.
