The sound of water droplets ticking and ticking from the dimly lit cave added a bit of horror to the already silent and hairy cave.

The footsteps of the two were echoed by the sound of the rain ticking, bringing a bit of a lively atmosphere and making the place seem not very quiet.

Zhang Rui walked in front of the road, Xiao Yu was behind the hall, and the two were silent all the way, just cautiously paying attention to the surrounding environment.

After walking dozens of steps, Zhang Rui could clearly feel that the road in the cave was going down, not straight ahead.

Also, the entrance to this cave is on the top of the mountain, and if it is a straight road all the time, then it will take a few steps to get through the mountain.

The stone walls in the cave are covered with scratches, layered and dense, Zhang Rui looked at the scratches on the wall, estimating how many wolves it would take to dig out this passage.

The wolf's claws are used for hunting, not for digging holes, looking at the wide passage in front of him, Zhang Rui shook his head.

It's really not necessary.

But he can't control too much, and the wolves have also hurt Xiaoyu, so they dig holes!

Zhang Rui no longer thinks about these meaningless things, the passage has been dug out, and it is too late to think about it so much, and it is not of much use.

They walked down for tens or hundreds of paces, and found that the walls of the cave around them were slowly narrowing, and after walking another hundred steps, the inner walls of the cave began to widen again.

Xiao Yu felt the change in the surrounding environment, and pulled Zhang Rui with her hand, signaling him to be careful.

Zhang Rui received Xiaoyu's information, and the speed of travel became slowed down, and now everything is stable, and they don't know anything about what lies ahead.

Zhang Rui seems to have returned to the night when he went to face the unknown wolf howl, but now that Xiaoyu is by his side, he is no longer single.

Now that most of them have succeeded, if one accidentally turns over the water before success comes, it will be the real damn.

As the two of them slowly moved, they could clearly feel that the light around them was changing, and the cave was slowly getting brighter.

Xiao Yu pulled Zhang Rui's arm, motioned for Zhang Rui to stop, and whispered in his ear.

"We're almost at the exit, be careful."

Zhang Rui nodded, looking around intently, beware of accidents, although if the accident happened, the person who solved the problem was still Xiaoyu, but he also did his part.

The light in front of them became brighter and brighter, and gradually, a wide hole appeared in front of Xiaoyu and Zhang Rui.

The sunlight sprinkled from the outside to the inside, leaving a spot of light, and between the mottled light and shadow, Xiaoyu and Zhang Rui walked out of this not long passage.

Zhang Rui walked in front, and as soon as he came out of the passage in the cave, he was fascinated and froze in place.

What appeared in front of Zhang Rui's eyes was an empty cave inside the mountain, just like a hall.

At the foot above the hall, two openings were opened, and sunlight poured in from between them, illuminating the hall brightly, without the dim feeling of walking in the dark in the passage before.

In the center of the hall, a pool attracted Zhang Rui's attention, and the stalactite pillars above the pool were dripping down one by one.

When each drop stays in the air, it emits a brilliant colorful light, drop after drop, like a dazzling gem.

After the small droplets fall on the pool, they fade into the colorful light, become pure white, and merge into the large collective of the pool, splashing the slightest ripple, spreading to the pool wall one by one.

After seeing enough of the stone pillars, Zhang Rui shifted his gaze to the surrounding stone walls, which were all crystal clear purple, like amethysts, shining in the sunlight.

Zhang Rui was completely intoxicated by the scene in front of him, indulged in it, and couldn't extricate himself.

Xiao Yu didn't pay attention to the back, and directly hit Zhang Rui's body, Zhang Rui only felt that two soft things suddenly stuck to it on his back, and he immediately woke up from the state of fugue.

Jumping to the side with a red face, he made room for Xiao Yu to come out, and let Xiao Yu come in and take a look.

Xiao Yu saw everything in front of her, her face was full of surprise, the layman looked at the liveliness, the insider looked at the doorway, she was not confused by the beautiful scenery in front of her, she was fascinated by the materials in it.

Both eyes are starry, looking at everything around him like a money fan.

I couldn't help but let out an exclamation!

Zhang Rui stood aside and touched his head, and sighed silently in his heart, the beautiful scenery in front of him could even fascinate the well-informed Xiaoyu.

Xiao Yu looked at everything around her, as if she was living in a dream, and let out an unbelievable cheer.

"The resources here alone are power stones that can be supplied to the soldiers of a legion in the clan for daily consumption, and it is a terrible thing to throw here!

There is no heavenly principle, and there is no royal law!

It's out! Brother Zhang Rui, we sent it! ”

Xiaoyu let out bursts of cheers, and Zhang Rui was inexplicable.

"Xiaoyu, where did you get the power stones, these purple stones?"

Xiao Yu nodded, "This is the power stone, and it is a very pure power stone, this energy stone is a hard currency circulating in the universe,

Our ordinary life and cultivation are inseparable from the power stone, and the energy rich in the power stone can be easily applied to all aspects.

This kind of energy extracted from power stones has many advantages, and even the energy of the mecha is made from the energy in the refined power stones. ”

Xiaoyu simply gave Zhang Rui a brief overview of the knowledge points about the power stone, so that he could have a general impression.

Zhang Rui nodded after hearing this, the role of the power stone in the cosmic civilization is like the role of electricity on the earth, and without water, everyone can barely survive a few days.

But once the power goes out, it's like the world is destroyed, you can't do anything, and it's boring.

"Hey, what's that?" Xiao Yu saw the pool that was very special at first glance.

Pulling Zhang Rui to the side of the pool, Xiaoyu looked at the pool in front of him, bowed his head and groaned.

Zhang Rui saw the pool in front of him more clearly at close range, there was not much liquid in the pool, only a thin layer, which accounted for about one-third of the height of the pool wall next to it.

Just standing next to him, Zhang Rui took a few breaths of the air around him, and he felt that his whole body was comfortable, as if he had been stimulant, but there was no obvious negative effect.

Just when Zhang Rui was puzzled, Xiaoyu suddenly bent down, dipped his index finger in the pool, and then put his index finger into his mouth.

Zhang Rui didn't come to stop Xiaoyu in a hurry, all this has happened, after Xiaoyu closed her eyes and felt it carefully.

She opened her eyes, revealing a look of ecstasy, Zhang Rui had never seen Xiao Yu so happy, Xiao Yu had just found so many energy stones and was not so happy.

"Brother Zhang Rui, this is an energy pool that has evolved to the extreme, and it contains gentle and easily absorbed energy, which is enough for you to absorb Brother Zhang Rui.

This side of the energy pool is our goal! Xiao Yu pointed to the pool in front of him and said with an oath.
