I, with a long knife in my hand, can only do one move

The chest is warm and comfortable.

When you are loved by your mother, when she says "I love you", the feeling of being surrounded by happiness, even in the cold sea, can make the heart beat faster.

Are these "hearts"?

"Is this...is love?"

Ai Xueer muttered to herself thoughtfully, as if she had found some answer, "Ai Xueer seems to understand...what is love."

"Have you understood so quickly?"

"Hmm...probably, but...Ai Xueer can't explain it."

"There's no need to force yourself to explain. You can't even speak well."

"....Well."

The girl nodded and said nothing more.

Cheng Rang then quickly climbed up the rock wall. He was going to confirm the location of the two fractures of the water source first. At least the information on the fault structure would be meaningful for this trip.

With the help of purple light ball

Under the lighting, Cheng Rang soon saw the white waves pouring out of the break not far away. The sound of the waterfall that could be heard before came from this.

And Ai Xueer followed Cheng Rang in the water, watching his behavior curiously.

Pulling out the knife and inserting it into the steep rock wall, turning over and standing up, Cheng Rang freed up a hand to catch the cup of water.

Tasted it, there is a little sweetness in the cold, it is drinkable fresh water.

After confirming that this is the outlet of the underground water source leading to the settlement, Cheng Rang's next goal is to find another water outlet that was cut off, which is the water vein leading to the settlement.

But in such a large cave area, it is too difficult to find a small opening that should have been quiet, not to mention that the surrounding areas that are not illuminated by the light source are still invisible.

"Cheng...do you need...help?"

At this time, Ai Xueer's voice came from the water below the rock wall.

"Eh? Can you see it?" Cheng Rang waved the light ball in his hand a few times, and the purple light illuminated the water surface under him a little, but due to the distance, he couldn't find it in the dim shadows. Ai Xueer's figure.

"Yes... In the dark, as long as there is a faint light, Axel can see clearly."

For sea-dwelling species, with such a light source, it is almost like daytime, and the vision will not be affected in the slightest.

Cheng Rang's eyes lit up immediately, then this was really a help!

Pulling out the long knife stuck on the rock wall, Cheng Rang returned to the water surface with a few vertical leaps.

"Is there another hole like this in the rock wall here?"

"Yes..."

"where is it?"

......

Under the leadership of Ai Xueer, Cheng Rang found three holes. After comparing the direction of the water veins on the map, he determined that the hole closest to the underground water outlet was the water vein that was cut off to the settlement.

But the straight-line distance between the two is probably more than 200 meters... It is enough to prove how huge this void formed by unknown reasons is.

If you look at it from a bird's-eye view and compare the void to a circle, the break of these two water veins is probably only on the dividing line at the upper quarter of the circle.

"200 meters..." Cheng Rang pondered his jaw and began to think.

In fact, Cheng Rang's original plan was to cut a hilltop and fill the bottom of the cavity so that the water could fill the bottom faster and then circulate.

However, according to the conditions of the water below, the bottom of this cavity seems to be in communication with the sea water. If you want to rely on filling, it should not be enough.

What's more, I also met a sea dwelling species...

Ai Xueer tilted her head to meet Cheng Rang's gaze.

"Ashelle."

"Yes?"

"If it is a sea dwelling species, can it control the water flow?"

Seemingly overwhelmed by this question, Ai Xueer frowned lightly, and after a while slowly said: "No, I don't know..."

Cheng Rang was not surprised by such an answer, he waved his hands and said, "Hey, yes... After all, you can't even speak the language of your own race, let alone other things, so pretend I didn't say it. "

"Cheng... what do you want to do?"

"I want to connect these two water outlets, can you think of any way?" For this naive and blank sea-dwelling girl in front of her, asking this kind of question is just pure curiosity, and there is no distraction If it is different from the inherent thinking, maybe she can give herself some different suggestions, so Cheng Rang asked a question.

It doesn't matter if it's a whimsical answer, at least Cheng Rang can't think of a way to connect the two nozzles in the air, and it must be stable and efficient.

Ai Xueer nodded her chin, glanced back and forth between the two nozzles, and said slowly: "If you want to connect the broken here... with that... Wouldn't it be nice to dig another hole between them?"

"Dig another hole?"

Ai Xueer blinked her eyes, tilted her head and said, "Isn't it right?"

Cheng Rang turned his gaze back to the mouth of the waterfall that was constantly surging out, and a flash of inspiration flashed in his mind.

correct!Digging!

Just like before when the exclusion zone was attacked in Hershalymzlot, only in reverse.

When there was a traffic jam on the originally smooth road, Cheng Rang used the fastest method, with the shortest straight-line distance between the two points—that is, he pierced through a whole block of buildings in front of him and rushed to Isabella's place. side, chopped the stone giant into pieces.

The current situation is that the road in the middle is too wide to pass through, so it is only necessary to block the gaps on both sides, and then go around the mountain wall next to it, dig a new path inside, and block the two gaps. If the fracture is reconnected, won't the problem be solved? !

Cheng Rang, who was limited in his thinking at first, really didn't expect such a simple method, because he saw too many messy things like supernatural powers, spells, and magic, and he always thought about how to use those fancy things to kill the couple. Connecting, but did not consider the simplest, simplest, and most feasible and reliable method.

burrowing....

"Why didn't I think of it, it was a great help, Ai Xueer!"

Cheng

Just hammer the palm of your hand and do it as you say, just dig a hole. With my current ability, it can't be easier.

"No...you're welcome..." Ai Xueer's cheeks were slightly red, and she covered her mouth and said softly.

For some reason, when she saw that Cheng Rang was happy because of her help, she also felt very happy, and the corners of her mouth turned up unconsciously.

Chapter 34 Promise and parting

Starting from the truncated hole, after choosing a direction, Cheng Rang started digging.

It is said to be digging, but it is actually more like "drilling" past...

"drink!"

Taking a deep breath, he twisted his wrist and stabbed the long knife out. The spiral sword energy turned into a blade and released, smashing the rock wall in front of him like cutting tofu.

The first hole was "drilled" out, walked to the end of the cave, adjusted the direction, and repeated.

"drink!"

Rumble!

Repeat—

rumbling....

In the mountain composed entirely of hard rocks, broken stones torn into powder by the energy of swords and swords fell out of the sloping hole in waves, and Axel, who was watching from the sidelines, was ashamed.

"Wow~"

Drilling into the water to avoid the follow-up dirt and gravel, Axel, who had cleaned herself up again, pulled some distance away, and carefully poked her head out again.

But except for the rock wall where there was movement from time to time, Cheng Rang's shadow was no longer visible.

Time passed slowly, and the hundreds of meters long cave tunnel was finally excavated to the end, and Cheng Rang could even hear the sound of water hitting the other end of the rock wall.

Almost the last hit.

"drink!"

boom--

The sword energy penetrated the rock formation, smashing everything in front of him, and then the raging water flow was diverted by a sudden fork and poured into the cave.

Got through!

Being washed out of the cave along the water flow, Cheng Rang cut two large stones off another rock wall, used them as plugs, and kicked them into the cut-off hole one by one.

With two loud bangs, the sound of the waterfall's water flow was completely cut off, rushing along the newly dug passage in the mountain.

"You're done, perfect!"

In this way, the new passage was connected, and the underground water source cut off by the hollow returned to the vein that was about to dry up, and flowed continuously to the distant settlements.

The task was perfectly solved, and Ai Xueer also had a lot of credit. If it wasn't for the method she proposed and her help in finding the opening, Cheng Rang himself would not know how long he would have spent here.

It's time to bring the good news to Rick and the others...

But when Cheng Rang stood on the shore with his hips akimbo, and looked at the sea-dwelling girl who poked her head out of the water not far away to look at her, she couldn't help feeling a little distressed.

——If she left by herself, what should she do?

"Ai Xueer." Cheng Rang squatted down and gently waved to the girl in the water.

"...?"

When she swam to the shore, Cheng Rang reluctantly said, "Ai Xueer, my mission is complete."

"Mission complete? Can Ai Xueer help?"

"Well, you helped me a lot, thank you."

The girl's eyes sparkled with excitement, and she laughed.

"So happy!"

"But it is also because I have completed the task, so it is time for me to go back."

"....go back?"

As if she didn't understand Cheng Rang's words, the smile on Ai Xueer's face gradually disappeared, and her crystal lips moved several times.

"Go back...where?" The tone was full of doubts.

Back to the place where I came, Cheng Rang wanted to answer her like this.

But thinking of the girl in front of her who has lost all her relatives and knows nothing about this world, she may even be trapped here all the time, with no food source.... She can only wait for death in the dark.

He couldn't open his mouth anyway.

"I can't stay here forever..."

"Why?" Ai Xueer's tone became anxious, as if she was afraid that the person in front of her would disappear suddenly, she jumped out of the water and grabbed Cheng Rang's clothes tightly.

"Cheng...can't stay here with Ai Xueer...can you live forever?"

Cheng Rang was silent for a long time, and finally said: "Sorry, no..."

The girl tugged at Cheng Rang's hands and clenched her hands even tighter, "Then, Ai Xueer...you want to go with Cheng!"

"But you are a sea-dwelling species...you can't live without sea water."

"There must be a way!" Ai Xueer suddenly yelled, her voice gradually choked up, and Dou Da's tears overflowed her eyes.

She asked Cheng Rang in an almost begging tone: "Cheng, don't leave Ai Xueer...Ai Xueer, there is nothing left...It's so dark here...If Cheng is not here, Ai Xueer I can't see anything...don't leave Ai Xueer anymore!"

She didn't want to be alone again, facing the broken shell, huddled in the dark and surrounded by fear.

If Cheng Rang hadn't come here, the two would not have met here.She was doomed to starve to death in a dark sea in a few days.

At that time, she didn't know anything, and she couldn't think about anything. No one could answer her question of why her mother wasn't around, so she was alone...

"There must be... there is a way...Ai Xueer, she is very smart...so, come up with a way..."

She could have tolerated such darkness and died knowing nothing.

But someone had brought light to her.

"There must be a way..."
