I, holding a long sword in my hand, only know one move

My chest feels warm and comfortable.

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

Are these "hearts"?

"Is this... love?"

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

"Do you understand so quickly?"

"Well...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 no more words.

Cheng Rang then quickly climbed up the rock wall. He planned to confirm the location of the two fractures of the water source first. This trip would be meaningful if he could at least obtain information on the fault structure.

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.

Ai Xueer, on the other hand, swam with Cheng Rang in the water, watching his behavior with curiosity.

Pulling out the knife and inserting it into the steep rock wall, Cheng Rang stood up and freed up one hand to receive the water.

After tasting it, it was cold and slightly sweet. It was drinkable fresh water.

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

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

"Cheng...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. The purple light illuminated the water below him a little, but due to the distance, he could not find it in the dim shadow. Ai Xueer's figure.

"Yes... In the dark, as long as there is weak light, Ai Xueer can see clearly."

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

Cheng Rang's eyes suddenly lit up, this was really a big help!

Pulling out the long knife inserted into the rock wall, Cheng made a few leaps and returned to the water.

"Are there any holes like this on the rock wall here?"

"Yes..."

"Where?"

...

Under the leadership of Ai Xueer, Cheng Rang found three cave entrances. After comparing the directions of the water veins on the map, he determined that the cave entrance 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 two hundred meters... enough to prove how huge this hole formed by unknown reasons is.

If viewed from a bird's eye view, comparing the hollow to a circle, the fractures of the two water veins are probably only on the dividing line at the upper quarter of the circle.

"Two hundred meters..." Cheng Rang thought while stroking his chin.

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.

But according to the conditions of the water surface below, the bottom of this cavity seems to be connected with sea water. If you try to fill it up, it probably won't be able to be filled.

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

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

"Asheer."

"yes?"

"If it's a sea-dwelling species, can it control the water flow?"

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

Cheng Rang was not surprised by such an answer, he waved his hand and said: "Hey, that's right...after all, you can't even speak the language of your own race, let alone others, just pretend I didn't say it. "

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

"I want to connect these two water inlets. Can you think of any way?" For this innocent sea-dwelling girl in front of me, she was just out of curiosity and had no other thoughts. If she thinks differently, maybe she can give herself some different suggestions, so Cheng Rang asked the question.

It doesn't matter if it's a whimsical answer, at least Cheng Rang can't think of any way to connect the two water outlets through the air while ensuring stability and efficiency.

Ai Xueer nodded her chin, glanced back and forth between the two water outlets several times, and said slowly: "If you want to connect the broken here...and there... Wouldn’t it be nice to dig a new hole between them?”

"Dig a new hole?"

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

Cheng Rang turned his attention back to the mouth of the waterfall that was constantly gushing out, and an idea flashed in his mind.

yes! Dig a hole!

Just like when the quarantine zone was attacked in Hersharemzlot, 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 - he cut through a whole block of buildings blocking him and rushed to Isabella's place. On the other hand, chop the stone giant into pieces with one strike.

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

Cheng Rang, who was limited in his thinking at first, really didn't think of such a simple method. Because he had seen so many messy things like supernatural powers, spells, and magic, he always thought about how he could use those fancy gadgets to defeat these two people. connected, but did not consider the simplest, simplest, most feasible and reliable method.

Dig a hole....

"Why didn't I think of that? It's a big help, Ai Xue'er!"

Procedure

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 Xue'er, whose cheeks were slightly red, covered her mouth and said softly.

For some reason, when she saw Cheng Rang feeling happy because of her help, she felt equally happy, and the corners of her mouth turned up unconsciously.

Chapter 34 Promise and Parting

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

It's said to be digging, but actually it's more like "drilling"...

"drink!"

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

The first hole is "drilled" out, go to the end of the cave, adjust the direction, and repeat.

"drink!"

Boom!

Repeat again——

Rumble....

In a mountain composed entirely of hard rock, the gravel torn into powder by the sword, light and sword energy fell out of the sloping hole in waves, making Ai Xueer who was watching on the side look disgraced.

"Woo~"

After diving into the water to avoid the subsequent debris and gravel, and cleaning herself up again, Ai Xueer moved some distance away and carefully poked her head out again.

But except for the rock wall where movement came from time to time, Cheng Rang's shadow had long been invisible.

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

It's almost the last time.

"drink!"

boom--

The sword energy penetrated the rock formations, shattering everything in front of it, and then the raging water was diverted by a sudden fork in the road and poured into the cave.

Got through!

After being washed out of the cave by the current, Cheng Rang chipped two large rocks from another rock wall, used them as plugs, and kicked them hard into the blocked entrance of the cave.

With two loud noises, the sound of the waterfall's water flow was completely cut off, and it rushed along the newly dug passage in the mountain.

"It's done, perfect!"

In this way, new pathways are connected, and the underground water source cut off by the cavity returns to the veins that are about to dry up, and flows continuously to the settlements in the distance.

The task was solved perfectly, and Ai Xueer also had a lot of credit. If it weren't for the method she proposed and her help in finding the break, Cheng Rang himself wouldn't have known 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 hands on his hips and looked at the sea-dwelling girl who poked her head out of the water not far away and looked at him, he couldn't help but feel a little troubled.

——What will she do if she leaves?

"Ai Xue'er." Cheng Rang squatted down and waved gently to the girl in the water.

"....?"

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

"Mission accomplished? Did Ai Xueer help?"

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

The girl's eyes flashed with excitement and she smiled.

"Very happy!"

"But just because I have completed my mission, it's 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.

"Back to...where?" The tone was full of doubts.

Back to where I came from, Cheng Rang wanted to answer her this way.

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

He couldn't speak.

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

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

"Cheng...can't you stay here with Aixue'er...forever?"

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

The girl tugged at Cheng Rang's clothes and clenched her hands tighter, "Then, Ai Xue'er... I want to go with Cheng!"

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

"There must be a way!" Ai Xueer suddenly yelled, her voice gradually choked up, and big tears overflowed from her eyes.

She gave way to Cheng in a tone that was almost pleading: "Cheng, don't leave Ai Xue'er...Ai Xue'er, there is nothing left...It's so dark here...Without Cheng here, Ai Xue'er I can’t see anything...Don’t leave Ai Xueer behind again!”

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

If Cheng Rang had not come here, the two would not have met here. She was destined to starve to death in the dark waters within a few days.

At that time, she knew nothing and could not think about anything. No one could answer her question of why her mother was not around, so she was alone...

"There must be a way...Aixue'er, she is very smart...so, come up with a way quickly..."

She could have tolerated such darkness and died in ignorance.

But someone happened to bring light to her.

"There must be a way..."
