Early morning of September 19, Hindukr Basin, Eagle Rock City.

Eagle Rock is located on a hilltop flat ground in the mountains northwest of the basin, the city is only a few square kilometers in size and surrounded by cliffs.

The city has no walls, and there are not many buildings, but there is a towering stone tower in the center of the mountain, and there is a circle of small round four-story buildings around the stone tower, and some stone houses are scattered outside.

Although there are few buildings on the flat ground, there are indeed a large number of wooden houses and stone houses stacked on top of each other on the cliff leading to the top of the mountain, and these houses are not so much complete buildings as a door to the cave.

As soon as the day dawned, Rand was brought to this Eagle Rock City by the legendary panda man Shu Yun, originally Rand hoped to come back in two days, but Shu Yun smiled and said that he really couldn't wait.

The legendary pandaman took Rand to the tower in the center of the city, and took him to the mountains and rivers around the city, only to see that about 10 kilometers of the city, there was an alpine lake, and the emerald green water of the lake was embedded in the mountains like emeralds.

"The lake you see is the largest source of fresh water in the area: Cloud Lake, and the water source of the lake mainly comes from the melting snow in the mountains," Shu Yun said, "We will go to the ground of that lake and install the magic furnace in a moment!" ”

Rand stood at the top of the stone tower and said with some concern, "Your Excellency, this building we are in should be a dragon station, right?" Isn't it supposed to be only for dragons? If we stay up there like this, won't we be remembered by the dragons who pass by? ”

"Hahaha, you know a lot about the buildings here," Shu Yun said with a smile, "This was indeed a dragon station, and this city was once the territory of the feathered dragon god Ou Zhutai.

His family consisted of the Harpies and the Six-Limbed Aiwen, but he hadn't returned for thousands of years since he ascended to the throne, and the tower had become a flying platform for the Harpy leader. ”

As soon as the panda man finished speaking, a black shadow fell in front of the two of them, it was a huge and friendless harpy, more than 7 meters from head to toe, and the wings of the two colorful feathers were fully extended and even more than ten meters.

"Lord Shuyun, this is the Rand Galloping Horse Mage, right?" The harpy's face is beautiful and dignified, except for a slightly pointed beak, the appearance of a bird is not visible at all.

The pandaman nodded, "Yes, Leader Zhuoya, Lord Rand is very busy right now, let's hurry up!" ”

Without waiting for Rand to say anything, the harpy named Zoya grabbed Rand with her claws, and with a flap of her wings she flew him down the valley to the bottom of the mountain where the lake was.

What Rand didn't expect was that in addition to a 1-kilometer-diameter and 100-meter-deep lake at the top, the lower part of the mountain was completely blue ice, and there was only a small ice cave at the bottom of a few hundred meters of ice.

Rand in the cave, he kept looking at his head, looking at the light falling through the ice from the top, and was silent for a long time before exclaiming, "This is the power of that god?" ”

"Yes, the god of the feathered dragon, Oritai, once dominated the glacier, and before he left Eagle Rock, he used his power to bring this water to the local air life." Shu Yun confirmed.

"However, this cloud lake is in great trouble now," said the harpy Zoya, "there is a passage inside this iceberg that can connect the cloud lake on the mountain to the tributaries of the Benma River underground, so that the two water sources can complement each other, and Your Majesty's power maintains the water pressure between the channels. ”

"However, this year, the water level of the Benma River has dropped, and it takes more magic to pump deeper water sources, and once the water level of the Cloud Lake is too low and the two yangs shoot directly into the ice, it will melt the magic circle at the bottom of the lake, causing a permanent drop in the height of the bottom of the lake." The Harpy said worriedly.

"Doesn't our lake rely entirely on glacier snow melt to replenish water?" Rand wondered, "Then why do you want to intersect with the Galloping Horse?" ”

"The water source of the Benma River is originally the melting snow of the high mountains, and this mountain is like a magic tower of ice and water systems, which continuously absorbs water vapor from the air in winter and spring and fills the underground of the Benma River, and in summer and autumn, it needs to draw water from the Benma River to ensure the water level of the lake."

Shu Yun, the legendary panda man, explained with a smile, "Once the water level is too low in autumn, the magic patterns on the ice at the bottom of the lake will be burned by the two yangs, and then the height of the bottom of the lake will irretrievably decrease.

About 2,000 years ago, the depth of the entire cloud lake was more than ten meters, after a long-term drought in the basin, the depth increased by half a meter, and since then it has gradually deepened every year, the deeper the lake, the more water needs to be replenished in autumn, so it enters a vicious circle. ”

"So, you need the magic furnace pump to replenish the river water?" Rand nodded, probably understanding what Shu Yun meant when he said that it was too late.

"Yes, the weather was cold this year, so I wasn't in such a hurry, but recently the water of the Benma River has dropped sharply, and Eagle Rock City is located in the water source, and the dark river has pumped too much water to cause the groundwater level to drop, once it is unable to maintain the replenishment of Yunhu Lake, it will immediately cause the water level of Yunhu Lake to drop and feed back the groundwater."

"In other words, between the Cloud Lake and the Dark River, there will always be a connection, and the two can be regarded as one body of water, only because of His Majesty's great power that they are at different heights." The power of the gods shocked Rand far more than when he saw the ice lake just now.

However, when Rand looked at Shu Yun, he found that the panda man smiled at him with a different meaning.

Recently, the Dark River has continued to decline, because the construction of the Mogebao Ruins led by Rand has begun, and a huge amount of water has been pumped from the underground river to pour into part of the space of the ruins, or Rand himself has directly led to the current predicament of Cloud Lake.

Seeing that Rand probably understood, the panda man said, "So you still need to install the magic furnace as soon as possible." ”

There are no mineral deposits or leylines at the bottom of the Cloud Lake, but the mountain range where it is located is not far from Moge Fort, so Shu Yun directly suggested that the new magic furnace be connected to a magic circle and connected to the magic furnace in Moge Fort.

"Are you really sure you can do it?" Listening to the panda man's suggestion, Rand was a little puzzled, "The magic circle you said can't be done without demigods or gods?" ”

"The magic circle is ready-made, a few days ago, the god of the feather dragon issued an oracle, telling me that there is a magic circle in this underground itself, tens of thousands of years ago, this was his home, that is, he negotiated with a goblin magician, and used several magic furnaces in a surrounding town to supply the magic here."

There is no doubt that the town mentioned by Shu Yun is Mogerburg, and in his opinion, letting Rand come over today to install the magic furnace can be regarded as a continuation of the inheritance for thousands of years.

The installation process of the magic furnace is not complicated, the cooperation between Shu Yun and Rand is very tacit, after the installation is successful, Rand perceives the underground magic passage from the magic furnace, and after connecting it, he can even feel the situation of the Mogerburg magic furnace along the passage.

The leylines in the Mogerburg Mine continued to flow under the cloud lake with the magic channel, but this magic power did not enter the underground river, but rose with the glacier.

Inside the ice cave, Shu Yun, the panda man, and Zhuoya, the leader of the harpy, sensed the gaze from the gods, while Rant, who was still controlling the magic furnace, felt a pair of wise eyes appear above his head, and a pair of huge red and white wings surrounded the magic furnace.

"Your Excellency! It's Your Majesty who has come! Zoya exclaimed excitedly.

Before they could react, they heard the ice above them make a "click... click", but under the feet is the sound of "la-la-la" running water.

"What's going on?" Shu Yun felt that something was wrong, opened the portal, and pulled the harpy to the sky above the cloud lake.

Looking down from the sky, the water level of the cloud lake has not changed at all, but the color of the lake is slowly becoming lighter.

"Could it be...... The water at the bottom of the lake is frozen again? Zoya watched it for about 10 minutes and finally understood.

"Yes, and after freezing, the ice has grown in size, and the water level has not changed, so the lake continues to replenish the dark river." Shu Yun nodded.

"Oh! That is, the water of rivers and lakes...... None of them are missing? "The Harpy didn't understand the physical cause, but she understood the final result.

When the water depth of the cloud lake returned to 15 meters, the freezing of the bottom of the lake completely stopped, not only did the lake/river replenishment relationship return to the state it was thousands of years ago, but also because the bottom of the lake was linked to the magic furnace, even if the bottom circle was damaged, it could be repaired in time in the future.

Done, Rand rubbed Shuyun's portal into the air, overlooking the entire cloud lake, and listened to the legendary pandaman tell the ingenious design of the feathered dragon god Ou Zhutai.

"No wonder His Majesty Ozhutai was once the god of knowledge, and the magical design of this mountain is indeed very ingenious." Rand couldn't help but nod his head.

Just as Rand, Shuyun, and Zhuoya were loudly admiring the gods, large bubbles of about 1 meter appeared on the surface of the lake underground, and then with a "bang", a black square object came out of the water and floated above the water.
