Gao Jinglun targeting Ling Tianyu is indeed a bad thing, but it can also be a good thing.
Elder Zhu and the others would love for them to strike Ling Tianyu with full force, as only dire adversity, unrestrained adversity, can stimulate Ling Tianyu's limitless potential.
It makes him crave survival, being pushed into desperation can help him mature faster, and those teachings imparted to him can be mastered more proficiently. If it really doesn't work out, they can always intervene at a crucial moment to resolve the situation.
The opportunity for Ling Tianyu to be treated with importance has arrived; it's possible that being pushed into a tight spot might lead to some unexpected developments.
Starting the war again would take several more days; at least four to five days, as it can't be so soon, especially with their resting place destroyed, which requires proper investigation.
Ling Tianyu still has time to prepare.
