"What's going on? Formation?" Hu Bugui also flew into the air, stood next to Shen Luo, and asked in surprise.
At this moment, a large number of runes emerged from the yellow light on the ground, rushing towards the buildings of all sizes in the city and merging into them.
And those yellow lights seemed to be attracted and were absorbed into the building permeated with runes. In the blink of an eye, a layer of ice-crystal-like yellow shield formed around it.
In an instant, all the buildings in Chang'an City were covered with a layer of yellow shield.
When Shen Luo saw this scene, his eyebrows raised.
"This is a change in the Chang'an City defense formation. It will bless the buildings in the city with the Wu Earth spiritual light to protect the safety of the people inside." Several Tang Dynasty government disciples flew over and said.
Shen Luo already had some guesses in his mind, and nodded slightly when he heard this.
The buildings in the city were protected by a yellow light shield. The attacks from the demons in the city hit the shield and were all shaken away, without any harm to the people inside.
Those yellow shields look ordinary, but they are actually indestructible.
The priests and disciples of the Tang government who were protecting the people in various places in Chang'an City breathed a sigh of relief. They could finally free up their hands and use all kinds of magic weapons and secret techniques to attack the demons.
Those demons were ferocious and unruly, and when they saw that they could not kill the civilians, they immediately fought back.
The court officials and the Tang government disciples, without having to worry about the common people, also fought the demons without restraint.
For a moment, lights of various colors collided violently, and the loud noise shook for hundreds of miles.
At this moment, there were unusual movements in Chang'an City again, with bursts of dragon roars and tiger howls. In the four directions of east, west, south and north, spiritual light rose up and condensed into the shadows of the Azure Dragon, White Tiger, Red Tiger and Black Tortoise.
Densely packed star symbols also appeared above the sky, like a huge pot turned upside down. It was the Four Symbols Heavenly Time Array, slowly falling down.
This time there was no Taoyao interference, and the Four Symbols Heavenly Time Formation was quickly established.
The Western White Tiger is in charge of killing and is the most active. Seeing the demons rampant in the city, he immediately opened his mouth and spit out countless platinum-colored sword qi, shooting down like rain, instantly killing a large number of demons.
The Azure Dragon, Vermillion Bird, and Black Tortoise also launched attacks, with countless green woods, flames, mines, and other magical powers falling down, and the demons in the city were immediately slaughtered in large numbers.
When Shen Luo saw this scene, he felt relieved. With the two powerful restrictions, the city defense formation and the Four Symbols Heavenly Time Formation, these monsters could no longer cause any trouble.
"No, these monsters attacked Chang'an City for the second time, and it was also a case of much ado about nothing. The man behind the scenes controlled the attack on Chang'an City twice. Even if he didn't want to destroy the three realms as the fox shadow said before, his goal must be huge and it won't be resolved so easily. Could it be that his target is not the people of Chang'an?" Shen Luo's heart suddenly moved, and he said goodbye to Hu Bugui. His figure disappeared in a flash, and he appeared in the center of Chang'an City the next moment.
Shen Luo spread out his spiritual sense and explored the surroundings. He used all his strength to operate the Netherworld Ghost Eyes, shooting out a green light about ten feet long, mixed with strands of black light, and looked around.
"Huh!" A green light flashed in his eyes, and his expression changed immediately. He pinched his fingers and activated the soft brocade clothes on his body. The whole person disappeared again and fled towards the northwest of Chang'an.
Inside the Circular Mound, Yuan Tiangang sat cross-legged on top of the altar, activating the True Dragon Wuji Formation.
