The so-called back-row tickets are essentially standing tickets. While there is a small stool to sit on, those who make it to the back row are not likely to be high-ranking officials or wealthy individuals, let alone have the ability to participate in the auction. Having a place to stand is enough for them.
In simple terms, they're onlookers and casual bystanders.
Lin Zhen's spot is located next to the aisle, which is an advantageous position with a good view. Not only could he clearly see the auction situation on the stage, but he could also observe the VIPs passing by him.
The martial force of this planet is quite impressive, with the most powerful reaching the God Transformation Period. For instance, in the bath Lin Zhen just visited, there was a Divine Transformation guard.
But those who can transform into Gods are quite rare; reaching Longevity or the Three Flowers level is already considered impressive here.
