Flying through the air, Du You also sighed in relief. "Fortunately, they haven't established a portal in their main territory over there."
Each territory can only build a limited number of portals, for instance, a sixth-tier territory can establish up to six portals linked to Earth. Each time a level is raised, one more portal is added, which is a fixed rule.
Previously, Du You had been keeping an eye on several scrolls within his own space, all of which sealed sixth-tier Zombie Dragons and Ghost Dragons. Should any issues arise, he would immediately release them and then cover his own escape.
The reason he chose to boldly use the main gate was also because he feared being surrounded.
With the stable forces of a sixth-tier powerhouse present, Du You was certain the opponent had a sixth-tier territory. If the opponent's territory portal was open in this area, the appearance of sixth-tier military branches could encircle him, which would be very dangerous.
