An Lin's expression didn't change in the slightest upon seeing the arrival of Su Wenjun.
Everything was within his control. After all, he had traced Dong Guo's divine intent, and he knew that Su Wenjun was nearby.
Su Wenjun possessed the Return to Void Intermediate Stage cultivation base. This was not enough to kill An Lin, and if a battle did erupt between the two, a full-blown war between the Four Nine Immortal Sect and the Green Wood Imperial Family would be inevitable. He trusted that Su Wenjun knew how to weigh up the pros and cons and would come to the correct decision.
The other first-rate sects could just take the phoenix egg and run. However, where could the imperial family run to? Were they just going to leave the Purple Star State behind? The resources in an entire state definitely surpassed the value of a phoenix egg.
Hence, Su Wenjun wouldn't take the risk and nor would he dare to do so.
