The terrain in the small battlefield dictated that it was not suitable for a large army to march and fight. When the number was too big, the line would be too long, which would make the army too big and easy target for the four alien races.
But it was different now.
The four alien races' armies were weakening with many of them hidden in their base camps. Not many alien races were outside now. It wouldn't matter much if a small army of them sneaked their way over.
The base camp of the Asmodians was not far away from the human's. If Lu Li flew there at the top of his speed, it would only take four or five days. But since there were more than 1000 warriors and more than half were only at the Eternal Realm, the speed was impeded.
They marched and rested at intervals. Along the way, more than a dozen alien race teams sneaked up on them and about dozens were slayed. After 12 days, the army finally arrived at the base camp of the Asmodians.
