Ainsley's heart skipped a beat at the elder's words, but she still stubbornly believed that Jake must be safe.
She conjured a strong barrier for Jake at the last seconds, and although her action might be a step too late....maybe Jake did have a protective item in his spatial storage.
Some good items could be used immediately upon danger, even when the owner didn't take it out of the storage space and actively used them.
In a sense, Jake did have a lot of such items, especially when he was an influential and rich businessman.
But the item didn't respond because, in the last seconds, Jake's luck helped him to get out of the explosion intact without losing an arm or a leg.
If not for this, the moment the owner was about to face death, the rare protective items would be used up immediately and disappear into nothingness after saving the owner's life.
