Zhou Zhou's eyes lit up.
The Supreme Barrier can actually defend against attacks?!
There was actually such a benefit in upgrading his territory to Yellow Gold-Tier Elementary Grade!
In the past, the Supreme Barrier could only block the invasion of the Scarlet Fog and not any attack.
It was equivalent to a gas mask.
It could only defend against poison and not bullets.
Now that the Supreme Barrier had been strengthened, it meant that the city under his command would have two levels of Defense buildings.
The first was naturally the Wall.
The second was the Supreme Barrier.
If the enemy wanted to break through his city, they had to break through the Supreme Barrier first, then break through his city walls before they could attack the city.
This would greatly increase the safety of the territory.
