The Heavenly Race could deal with him through a Spatial Channel that had not yet been opened, which evidently required a price to be paid, otherwise, in the foreknowledge, the first two times he approached the Passage, the other party would have already made their move.
Although he did not know exactly how the Heavenly Race had acted or what means they had used to kill him with one strike, as long as that method wasn't available for unlimited use, he would have the opportunity to avoid it.
Foreknowledge began again.
In this foreknowledge, he used the Across the Heavens Shift at the very last moment, attempting to avoid that strike.
Although he successfully dodged the blow for the first time, evading death, the attack did not dissipate. Instead, it locked onto him and struck at him again.
