The roar of the fighter jet engines waxed and waned in the sky, while the thick smoke on the ground continued to billow. Many from Shu Country were looking up at the entangled planes, unable to discern which were their own.
Due to the distance, they could not make out the models of the planes, nor could they see who was chasing whom.
The bombers known as "flying pencils" began to head home, and the fighter jet troops from Qin Country also started to retreat. Their mission was to protect their own bombers; there was no reason to stay and fight.
After all, the bombing was over, their mission was complete, and the enemy before them couldn't be eliminated in a short period of time. Staying would only add to their own fuel burden.
Keep in mind, this is a place over 200 kilometers from the border, and their aircraft's combat radius is just over 400 kilometers.
