The tunnel is long, and only the quaint bronze lamps hanging from the walls are lit like beans, emitting a dim glow.

There is only a shallow layer of oil in the copper lamp, and I don't know how long the lamp has been burning, so that the lamp is full of dust, but the lamp oil has not decreased.

Under the dim yellow light, the raised characters on the walls reflect a light yellow light, as if bathed in layers of Buddha light, which looks quite mysterious.

"It is worthy of the Great Array of the Imperial Capital Defending the City, and these countless runes are just an energy path, which can be said to be the most vividly explained in the rune array."

Ning Xu rubbed the raised characters on the wall, and the energy flowed through the characters, and there were vague electric rays spreading out, bringing a slight tingling sensation.

"The spiritual power is flowing over there, the heart of the formation should not be far away, according to my brother, if the enemy contacts the center of the formation in advance, I'm afraid there will be a big problem, it's better to act first."

A buzzing sound sounded, Ning Xu subconsciously leaned back, and the arrow, which looked quite slender, flew past his forehead, and the arrow slashed, touching the hair of the arrow and almost turning into ashes.

When his body stopped slightly, Ning Xu's eyebrows swelled slightly, and the spiritual power of water spread out, drilling in the direction where the arrow was fired.

In the depths of the tunnel, a man dressed in black appeared in Ning Xu's mind, the man raised the slingshot in his hand, and another slender arrow landed on the string.

Unlike the arrows used in the longbow, this kind of arrow is obviously shorter, and the metal-like arrow reflects a faint blue light under the reflection of the fire, which is obviously soaked in a highly toxic substance for a long time.

As you can imagine, if you are shot, there is absolutely no good fruit to eat.

The bow-wielding man's movements looked quite slow, and some even deliberately pursued a certain sense of ritual, relying on the spiritual power that spread, Ning Xu could even "see" the green tendons on his hands that had burst out because of the force.

But all this was just an illusion, and in just a few breaths, several arrows soaked in poison shot out, each parallel to each other, perpendicular to the plane where it was solidified.

So much so that from Ning Xu's point of view, it was not five arrows at all, it was five small black dots, and connecting these black dots in pairs and twos happened to constitute a five-pointed star, just five arrows, in this narrow tunnel, for a while, it directly sealed all the positions that Ning Xu could move.

"Very strong!" Ning Xu was slightly shocked in his heart, but the five arrows were as fast as lightning, and he quickly realized that these arrows only needed a few breaths to shoot through themselves.

"Flame Phoenix Shield!" Ning Xu whispered softly, raised his hand and wiped it on his waist, and the giant axe disappeared instantly.

Immediately after, he only felt as if the blood in his body was burning, and an irrepressible burning sensation was filling his body, and then, red flames poured out from every pore of his body.

And not far in front of him, it was as if something suddenly collapsed, bursting out with a powerful devouring force, pulling those flames to condense into a huge shield in midair.

With the formation of the shield, a giant phantom behind Ning Xu stepped forward, knelt on one knee, and held the flame giant shield in his hand, and its body directly wrapped Ning Xu in it.

Guardian artistic conception, Yanhuang Spirit Shield!

With a ding, the arrow hit the shield, and a rather powerful force struck from the surface of the shield, Ning Xu was shocked, and subconsciously used the spiritual power in his body to offset this recoil, but the giant's phantom swept through a layer of ripples like ocean waves, and collided with the impact from the arrow, both of which were canceled.

And the spiritual power in his body had already poured out of the dantian, Ning Xu's eyes flashed with a hint of determination, he reached out and merged into the palm of the giant's phantom, holding the blazing flame shield, the flame shield touched his master's hand, and immediately began to shrink.

In just a few seconds, the huge shield, which was originally like a wall, almost cutting the passage in half, shrunk to a normal size, and was held in Ning Xu's hand.

But the flames that lingered outside the giant's phantom still swirled endlessly, like an endless sea of fire.

Ning Xu stepped on the soles of his feet on the ground and slammed his head, buried his head and shrank down, protecting his body in the shield as much as possible, and then ran in the direction of the arrow like a wild bull.

The tinkling sound was endless, one arrow after another came from afar, and through the gap in the sea of fire, Ning Xu could vaguely see that the arrow no longer flickered with ghostly light, but was pure white as gas.

Started using psychic arrows? It seems that the price of the previous kind should not be cheap, and he is reluctant to use poisoned arrows in this situation.

Such a thought crossed Ning Xu's mind like lightning, and almost instantly, he had already made a decision.

The distance was getting closer and closer, so much so that Ning Xu could even see the strange pattern of the mask on the face of the man in black.

"It's now!" Ning Xu continued to roar in his heart, the man in black raised the bow in his hand, and several spiritual power arrows glowing with white light left the string, saying that it was too late, and then quickly, Ning Xu's arm swung, and the shield surrounded by countless flames suddenly expanded, like a wall of fire, smashing towards the man in black with the swing of his arm.

Boom.

The voice was dull, and the arrow passed through Ning Xu's shoulder, taking away the slightest trace of blood, and at the same time, a huge giant axe appeared in his hand that was still intact.

Ning Xu roared angrily, stepped forward, and when his waist twisted, he drove his arm to smash the big axe Lu Qing, the flames on the axe were surrounded, and the heavy giant axe fell only a small distance away from the man in black.

The flames swirled, and the figure in black retreated, and the flames from the giant axe only burned off the hem of his clothes.

Successfully dodging the killing of the giant axe, the man in black breathed a sigh of relief, and then raised his bow quite proudly, as if to see the loss on Ning Xu's face, and then shot him.

He looked up, and there was no sadness on the young face that fell into his eyes, only a grin that was hideous to a little terrifying.

Almost instantly, the ground that was slashed by the giant axe suddenly cracked, and the roar erupted at the place where the giant axe and the ground touched, and the crack meandered forward, and the flames instantly burst out from the crack, and then exploded directly.

With a bang, the giant's phantom head shot and squatted to defend, bursts of fiery red appeared in its body, faintly condensing into pieces of beautiful feathers covering the surface of its body.

The waves of fire gushed out, but they were devoured at the first moment they touched the feathers, transforming into a steady stream of power, and the red flame energy crawled in its body, looking extremely eye-catching, and then directly drilled into Ning Xu's body, transforming into one flame spiritual power after another, replenishing his consumption.
