Lin Qing thought for a while, then suddenly asked with a worried look.

"It's okay, if it can't be filled, we'll just pour some water in from the outside."

Gu Nanxun comforted him.

"That's one way. Let's find some river stones to pave it in when we have time! Otherwise, it's too muddy."

"I have tomorrow off, I'll go with you to look for stones!"

Gu Nanxun looked at the riverbed in front of him and said with a smile.

Lin Qing nodded heavily, then thought for a moment and asked worriedly, "Do you think it will overflow after we fill it with water?"

She didn't really understand these things, but she had often heard about floods in certain places, so she asked Gu Nanxun about it with concern.

"No, we'll just dig up a few more and let them form a cycle."

Gu Nanxun explained with a smile.

Lin Qing nodded upon hearing this. She didn't know how to make the water circulate, but since her brother Nanxun had said so, he must know how, so she didn't ask any further questions.

In fact, Gu Nanxun didn't understand either, but he knew the system did, so he could just use points to have the system do it.

After discussing the matter, the two were exhausted. Their mental energy had been greatly depleted. They hadn't felt it before, but now the fatigue immediately surfaced. After returning home, they took a shower and went to bed.

...

The next day, Lin Qing and Gu Nanxun got up early. After eating breakfast and coaxing the children, they were full of energy and prepared to go find the river stone.

They drove to the riverbank in the suburbs. The stones along the riverbank were of various shapes and sizes.

"Brother Nanxun, what do you think of this place?" Lin Qing asked Gu Nanxun excitedly, pointing to the stones by the river.

Gu Nanxun looked at it, nodded and said, "Not bad, it's quite suitable, but it probably won't be enough. We may need to find a few more places."

Lin Qing nodded. "Then let's begin!"

After saying that, he first put his hand into the river and then spread his mental energy. Soon, the stones of different sizes in the river disappeared, and the river water visibly sank to the bottom.

"That's enough, taking any more will be too obvious!"

Gu Nanxun looked at the sinking river water and said with a smile.

Upon hearing this, Lin Qing stopped.

The two then found a place to store the car in their spatial storage, and then took out the hovercar that had been covered with an invisibility talisman.

The two boarded the hovercar and drove off to other rivers.

In this way, the two of them traveled through more than a dozen rivers in a single day, and finally filled the riverbed they had dug out with stones of different sizes.

"It looks much better this way."

The two returned to their space, and Lin Qing looked at the riverbed covered with stones and said with satisfaction, "Now we just have to wait to find the spring and let the water flow in."

Gu Nanxun wiped the sweat from his forehead and said with a smile.

"Let's get started!"

Lin Qing stared intently at Gu Nanxun with her big, watery eyes, her eyes full of excitement.

"System, mark the location of the spring and provide a design diagram for the water to circulate."

Gu Nanxun asked the system directly.

"Ding... The location of the spring has been marked, and the design blueprint has been provided. This design blueprint requires 10,000 points. Do you want to deduct them directly?"

"Deduct directly!"

Gu Nanxun answered directly, "10,000 points, not too expensive."

"This is amazing! The system can do this too."

Lin Qing looked at the map in front of her, her eyes shining. How could she not have thought of that! Her brother Nanxun was so clever.

"Alright, let's dig in these spots!"

Gu Nanxun patted Lin Qing's head and said with a smile.

So the two of them each found a spring and started digging with their mental power.

Soon, clear spring water gushed out.

Lin Qing looked at the gushing spring water and happily continued digging. Soon they had dug out all 10 locations marked by the system.

"Great! We finally succeeded!" Lin Qing clapped her hands excitedly as she looked at the 10 springs that were constantly gushing water.

Gu Nanxun was also standing beside her, gazing at Lin Qing with a tender expression.

As the spring water continued to flow in, a thin layer of water gradually formed at the bottom of the riverbed.

Looking at the riverbed in front of him, Lin Qing smiled and said, "It seems that it will take some time to fill the riverbed."

Gu Nanxun nodded: "Okay, now we just need to wait."

"Then let's plant some willow trees along the river! That would be even more beautiful," Lin Qing suddenly suggested.

Gu Nanxun smiled and nodded: "I'll listen to you."

Next, the two dug up some willow trees from outside and planted them in the space. To help the willow trees survive better, they watered them with some spiritual spring water.

Perhaps due to the effects of the spiritual spring water, the originally withered willow tree visibly sprouted some tender green buds, and in a short period of time, green leaves covered the entire willow tree.

In the blink of an eye, a row of tender green willows appeared on both sides of the riverbed. A gentle breeze blew, and the willow branches swayed, adding a unique vitality and beauty to the space.

"Nan Xun, Lin Qing, what are you doing!"

Zhao Jinxiang had worked overtime all night and hadn't slept. He had just returned home and saw the scene before him as soon as he entered the space, so he asked curiously.

"Uncle, we dug a river and planted willow trees!"

Lin Qing excitedly introduced it to Zhao Jinxiang.

Zhao Jinxiang stared wide-eyed at the seemingly endless riverbed before him and exclaimed in astonishment, "This...this...when did you dig this?"

Seeing her uncle's surprised expression, Lin Qing chuckled and said, "What do you think of the ones we dug up last night? Pretty, right?"

Zhao Jinxiang was even more surprised when he heard this, "You dug it all in one night, how did you manage to do it?"

"Uncle, don't be surprised. We dug it with our mental power. This is a power given to us by the space, so it can only be used inside the space. It definitely won't work outside."

Gu Nanxun knew what his uncle was surprised about, so he explained with a smile.

Zhao Jinxiang breathed a sigh of relief upon hearing this: "Alright, I thought you two had become immortals! You dug such a large riverbed in one night."

After Zhao Jinxiang finished speaking, he paused for a moment, and then continued, "You two young couple really know how to make a fuss, but it does look absolutely beautiful."

"Haha, Uncle, it will be even more beautiful when the river is full. I'll raise some fish in the river then, and we'll buy a small boat. It'll be a great place to go for a trip!"

Lin Qing said with a smile.

"You two really know how to enjoy yourselves. It would be great if the children could come in too."
