To use a game map to illustrate the current situation on the battlefield, in one third of the Earth's allied forces in the rear, the enemy red dots had been completely destroyed, leaving behind a large number of green dots.
Also, the green dots were moving forward slowly but surely as they ate up the red dots.
At this rate, the allied forces would eventually gain the upper hand and slowly eat up Thanos's ground troops.
Thanks to Luke, the king of snipe shots who never missed a shot, the attacks on the rear of the allied forces were significantly reduced.
The firepower support gradually suppressed Thanos's ground troops, and they weren't pushed back.
A stable rear provided the Karma-Taj sorcerers a better environment to work in.
Apart from the main force that had been dispatched at the very beginning, these sorcerers never stopped opening portals and bringing in reinforcements from all over the world.
