Bab 4543: Don't even think about leaving when you're here (1)

A few dark shadows approached the tower, trying to sneak into the core area to get more information.

As they sneaked all the way here, no one saw through their hiding methods, which made these shadows even more confident.

It seemed that this Tower City was nothing more than this.

The moment they neared the tower, a buzzing sound suddenly came, and countless runes fluttered like snowflakes.

It was as if something had been activated all of a sudden, releasing a terrifying aura.

The seemingly peaceful and harmless loucheng turned into a Tiger's Den and Dragon's pool in an instant, as if it was going to swallow the enemies who sneaked in.

The figures of several infiltrators were also exposed at this moment, and the spell techniques that concealed their figures were completely ineffective.

"Not good, quickly retreat!"

The cultivators who tried to sneak into the city were slightly shocked and chose to retreat without hesitation.
