When Daoist Ji unleashed the "Six-Revolution Sun Dissolving Arrow" just now, Zhang Yan's Heart and Spirit was already on guard. For the other to risk his life and forcefully activate this spell under the threat of the Purple Cloud Divine Thunder, there was no need to think further—he could tell that this strike must contain immense power.
When faced with Divine Passage Skills, if a Cultivator knows he cannot withstand them, those whose Escape Skill is superior can simply seize the opportunity to flee, and once the spiritual mechanism is exhausted, the spell will naturally dissolve.
Zhang Yan possessed both the Five Elements Escape Technique and the Sword Escape Technique, so he could have easily withdrawn to a great distance. Yet doing so had its drawbacks: if the Purple Cloud Divine Thunder Net were left without anyone to control it, it would grant Daoist Ji a chance to escape. Still, before figuring out the details, he was unwilling to take the blow head-on.
