The appearance of the canine-toothed monster seemed to have turned on a switch, and the originally dead and quiet underground space boiled in an instant, and there was a faint stream of shouts and killings in all directions.

Everyone in the Flint Squad was shocked, they didn't expect so many people to come in here.

On second thought, however, it's not surprising that the underground space is vast, and it's located in a mountainous area, with multiple entrances.

And since they could detect the strangeness of the black-winged monsters and the canine-toothed monsters, most of the others could do the same, so it was not difficult to follow the monster's trail.

"Let's move on!" Han Ying glanced at the deep darkness in the distance and turned his head and said in a deep voice.

He didn't have any plans to follow the sound to contact other teams in the past, but right now in the ruins, the wealth is moving, and everyone who enters the underground space is a potential enemy.

The group rested for a while, wrapped up their injuries, and then continued to walk.

Halfway through, the canine-toothed monsters were like a tide, attacking wave after wave, almost every three or four hundred meters forward, they would collide with a wave of canine-toothed monsters, as if endless, fearlessly blocking their steps.

By the end, even the Blackwinged Monster appeared.

The subterranean space was home to the black-winged monster, swooping silently from the air, its obsidian-like body melting into the darkness around it, barely noticeable to anyone present for the moment before the attack.

And when the flint team noticed the black-winged monster, the latter's razor-sharp claws were already within twenty centimeters of Cui Yaoqi's back heart.

This scene made Han Ying and the others change color, and Cui Yaoqi finally felt the fierce wind behind her, but at this time, it was too late to dodge, and the shadow of death instantly hung over her heart.

At the last moment, Du Mu suddenly threw out the long sword in his hand, driven by the huge force, the long sword turned into a cold light that tore through the void, and swept seven or eight meters away like thunder, and at the moment when the claws of the black-winged monster could touch Cui Yaoqi's back, it blatantly pierced into its neck.

In the piercing scream, the black-winged monster seemed to have been hit by a cannonball, and its entire body suddenly fell out, grazing the ground and rolling out of seventeen or eighteen meters before it stopped, and the neck was already full of cracks, and there was no sound at all.

Seeing this, Han Ying and the others breathed a sigh of relief, Cui Yaoqi recovered from her fright, wiped the cold sweat from her forehead, and turned her head to Du Mu and smiled gratefully.

"Good job!" Xu Qing split a canine-toothed monster with a sword, gave Du Mu a thumbs up, and threw a spare long sword to him by the way.

Taking the long sword, Du Mu drew his sword and slashed away the canine-toothed monsters that were attacking around him, and then raised his head to look into the air, and a black shadow flashed away.

And a black-winged monster!

Du Mu stared intently at the deep darkness in the sky, the black-winged monster was like a fish in water in this environment, and its speed was as fast as a ghost, even if he had Lan Foot and Moon Step, it would not be easy to kill the other party.

It's a pity that it's not appropriate to use the Darkchaser right now, otherwise it would be easy to deal with the Blackwinged Monster.

After thinking for a few seconds, Du Mu gestured to Zhou Yang and pointed upward, the latter understood, nodded slightly, then looked up at the sky, stared for a moment, and shot an arrow.

The arrow targeted a shadow next to the pillar, and before it could reach, a black-winged monster burst out of the shadow and swept towards the other pillar.

Zhou Yang had already prepared, and shot the second arrow almost without pause, targeting the air about two meters in front of the black-winged monster, sealing its forward direction.

Seeing this, the black-winged monster's body suddenly stopped, avoiding the arrow, and taking advantage of this gap, Du Mu had already raised his foot and kicked upwards with lightning, and the white slashing wave roared out, accurately hitting the black-winged monster in mid-air, cutting it in two.

Without the black-winged monsters watching, everyone was finally able to concentrate on dealing with the canine-toothed monsters, and after a while, the beasts were finally wiped out.

"Captain, you can't go on like this!"

After the battle, Song Dongbo took a few breaths, looked at Han Ying and frowned, "Forget about the canine monsters, those black-winged monsters are much more troublesome, a beast group of this size just now, we are estimated to lose our combat effectiveness in two more waves!"

Han Ying's gaze swept over everyone, except for Du Mu, the rest of the people were injured, and even Zhou Yang, who had been under the protection of Xu Qing and Cui Yaoqi, was caught on the shoulder by the canine-toothed monster, not to mention that everyone had experienced a lot of battles along the way, and their physical strength had already dropped to the cordon, and it was barely enough to deal with a wave of beasts in this state, let alone two waves.

After thinking for a while, Han Ying said in a deep voice: "Go a little further, if we still don't find it, let's leave here and go outside to repair and come back!"

Everyone bowed their heads and came here, and no one was willing to give up easily unless they had to.

Fortunately, the luck of the flint team seemed to be better, and on the next road, everyone did not encounter the beast herd again, and after advancing another seven or eight hundred meters, a ray of light finally appeared in the distance.

Everyone was in high spirits, and rushed over at a faster pace, getting closer, only to find that the light was actually a halo of blue, purple and blue, and the hazy light was like a rippling water wave, constantly circulating on the surface of the halo, which was beautiful.

"What is this?" Xu Qing's eyes widened, and he looked closer to the halo and looked at it carefully, with a look of eagerness on his face.

Everyone in the flint team stepped forward to take a closer look, and no one noticed the strange look on Du Mu's face that fell behind.

How can there be a halo here?

Du Mu couldn't suppress the consternation in his heart.

The halo is a symbol of the dream zone!

The halos he had encountered so far had invariably been passageways connecting two dream areas, which had either been conquered by the Nightmare invasion and completely transformed, like the church area or the school area, or were in the process of transformation, such as the mountain grassland.

And since there will be a halo in this underground space, doesn't it mean that this is a dream area?

"Wait, if that happens, could it be that those black-winged monsters and canine-toothed monsters are nightmare creatures, but why didn't I get a hint?"

Du Mu was puzzled.

At this time, the rest of the Flint Team had finished discussing it, and the halo in front of them was likely to be a door, and the other side led to a certain place, and they decided to go inside and take a look.

Since it was not yet known what kind of danger was hidden on the other side of the halo, the flint team naturally did not take the risk of letting everyone go in with them, but prepared to let one person go in to explore the way first.

Han Ying took on this task on the grounds that he was the strongest, and if he encountered danger, he would be more sure to deal with it than others.
