After a while, Xu Qing also cried out in surprise, and the injuries on his body were completely recovered.

At this moment, everyone no longer had the slightest doubt about the role of fairy bean chocolate, and they took one from Du Mu's hand, and in a blink of an eye, the flint team returned to the state of its heyday.

"Du Mu, this thing is very expensive, isn't it?" Han Ying was amazed for a while, and then as if he remembered something, he looked at Du Mu with a little embarrassment.

Something that can be compared to a healing potion is not ordinary no matter how you think about it, and the flint team and Du Mu have only known each other for two days, but they have obtained such a precious thing from the latter.

Du Mu shook his head: "Don't care, this thing is actually not very useful, it is not precious." ”

The healing effect of fairy bean chocolate will gradually weaken with the growth of the user's strength, and when Du Mu just got the fairy bean chocolate, this thing is quite practical for him, but now it is better than nothing, and it is good to occasionally use it to replenish his physical strength.

Cui Yaoqi and the others are not seriously injured, most of them are traumatic, and fairy bean chocolate can exert obvious effects, and if they are replaced with moderate or severe injuries, I am afraid there is nothing they can do.

The injuries were healed, and the physical strength was restored to the peak state, and everyone in the flint team naturally no longer hesitated, lined up in formation, and plunged into the dark cave.

Han Ying and Du Mu each held a fluorite for lighting, and the milky white light sprinkled five meters away, presenting the scene in the cave in front of them.

As far as the eye can see, there is a passage wide enough for four people to walk in parallel, and the stone walls on both sides and above are made of square stone bricks, with obvious traces of artificiality.

The floor of the passage was very clean, free of the filthy, foul-smelling, and white filth characteristic of the caves inhabited by wild beasts that had been seen before.

The sound of gentle footsteps broke the silence in the passage, and everyone in the flint team watched the surrounding scene vigilantly, until Du Mu pulled their attention away.

"There's light ahead!"

Everyone squinted their eyes and looked ahead, and sure enough, there was a faint glimmer at the end, but it was not very obvious.

This discovery lifted their spirits and accelerated their pace slightly.

After a while, Du Mu saw the end of the passage, and everyone couldn't wait to pass through the passage.

The light dimmed slightly, and then brightened, and Du Mu looked up and saw an extremely empty underground space.

The thick and simple aura that rushed to his face made him lose his mind for a moment, as if he was in a certain layer of the Holy White Tower in the dream realm, but in an instant he came back to his senses and realized that he was still in reality.

Du Mu looked sideways, Cui Yaoqi and the others widened their eyes and looked at everything around them in distraction.

No wonder they are so out of shape, it's really that the underground space in front of them is too strange, not to mention the vast area that can hardly be seen, just the towering giant pillars that stand straight all around, and the surface is engraved with mysterious cloud textures, giving people a sense of insignificance in the face of giants.

The entire underground space reveals a quaint and distant atmosphere that has been precipitated over the years.

A hazy light filled the entire underground space, but it was impossible to see where it came from.

Looking at the dome where only a vague shadow could be seen overhead, Du Mu couldn't help but wonder if the underground space in front of him was built by hollowing out the interior of the entire mountain.

After a long time, Han Ying and the others recovered from the shock, and walked forward in amazement.

"This is the ruins, right?" Cui Yaoqi muttered to herself.

The sound was very clear in the silent underground space, and everyone nodded in unison, there is such a majestic underground space in the mountain, there is no other explanation except for the ruins.

After watching curiously for a while, Han Ying gathered everyone together and continued to walk forward.

Looking ahead, the distance is dark like an abyss, and there is no edge in sight, and after moving away from the entrance of the passage, only majestic stone pillars are left in all directions, giving people the illusion of stepping into some ancient fantasy space.

The entire space was immersed in an endless, silent dead silence, and the flint team advanced for a while before they gradually got used to it.

"We seem to have walked a kilometer or two, right? Why haven't we seen the end yet?" Xu Qing suddenly spoke, although the voice was not loud, but it was particularly abrupt in the dead underground space, startling the others, and everyone turned their heads and glared at him.

Xu Qing shrunk his neck.

Han Ying was silent for a few seconds, and was about to say something, when his expression suddenly moved, and he looked ahead vigilantly.

Du Mu was the first to react than Han Ying, raised his foot and kicked up suddenly, and the white slashing wave suddenly formed, whistling through the darkness in front of him, and submerged into it.

Almost at the same time, there was a muffled cry in the darkness ahead, accompanied by a crisp click like a stone shattering.

This sound was like a cannon salute that kicked off the battle, and in the next second, countless canine-toothed monsters burst out from the darkness in front of them, roaring and rushing towards everyone.

A sharp whistling sound sounded in an instant, and the canine monster that rushed to the front slammed down, its body fell backwards, and it fell to the ground motionless, and there was a sharp arrow in the center of its forehead, and the tail rod still trembled slightly.

In the center of the team, Zhou Yang calmly and quickly pulled out the second arrow and put it on the string.

Han Ying and Song Dongbo were already shouting towards the herd, while Cui Yaoqi and Xu Qing were guarding in front of Zhou Yang, responsible for blocking the attacking enemy for the latter.

Looking at Du Mu again, he had already disappeared in place, one step ahead of everyone else to kill the beasts head-on, and the sword light in the sky swayed out, setting off a rain of blood in an instant.

There were far more canine-toothed monsters than the Flint Squad had ever encountered before, and there were no less than fifty of them in all directions, full of black jade bodies and sharp white fangs.

The shouts and roars instantly tore apart the dead silence of the underground space.

If it weren't for the flintstone team who had taken fairy bean chocolate before coming in earlier and recovered their injuries and strength, I am afraid that the moment the attack appeared, they would have been killed and injured.

Even so, it took a long time for everyone to fight to the death before they wiped out all the canine-toothed monsters.

"This amount...... It's too foul!"

After the battle, Xu Qing panted and said, there was an additional wound on his abdomen that was nearly two centimeters deep, which was scratched by the claws of the canine-toothed monster, and the blood that flowed out soaked the nearby clothes red.

The rest of the people did not answer, but looked around intently, as if they were listening.

In the boundless darkness, faint shouts of killing came from all directions.

Han Ying and Du Mu glanced at each other and immediately understood each other's eyes.

Someone else in this underground space has come in!
