The four gates of heaven, earth, man, and dog

There was an ancient city that was extremely huge. It was like a primeval beast that lay on the ground.

The city walls were so high that they pierced through the clouds. Looking from afar, it was impossible to tell how big this giant city was because the edge of the city walls could not be seen.

It was as if they could only see one side of the city wall, but not the ends of the wall.

Star-moon ancient city!

Everyone's heart moved.

"Let's go!"

Bai Li flew forward, and the others followed closely behind.

As they got closer and closer to the city wall, they realized how huge it was. The wall was ancient and filled with the aura of time. It was as if it had crossed time and space from the beginning of the universe.

Soon, they arrived at the foot of the city wall and found a city gate.

No, to be precise, there were four doors. Behind the four doors, there was a common passage that led into the city.

The four doors were all different.
