Chapter 19]

The strength of the first fountain was very sufficient, and it was sprayed to a height of 100 meters at night with wind and snow, and after he flew out of the fountain to the side, he also looked at it a little, and found that the location of the fountain was in the ruins of the Dugu Palace.

So he hurriedly removed the broken bricks and tiles in the ruins, and then blocked some gaps in the walls of the original Dugu Palace, and finally as time passed, the pressure under the ground gradually stabilized, and the hot spring did not spray ferociously to a hundred meters high, only a fountain ten meters high.

Nearly an hour later, the entire Dugu Palace was completely covered with a gentle hot spring, and at this time, the fountain no longer spewed, but some spring water slowly flowed out from the gap, reaching a balance with the evapotranspiration overflow of the entire hot spring pool.

In this way, the original Dugu Palace has completely become a large hot spring hot pool with a temperature of 45 degrees Celsius.

The city wall of the Dugu Palace is more than 20 meters high, but the depth of the hot spring pool is only 15 meters, so it will not continue to increase the hot springs.

With this puzzle, Fenghua Snow Night Pole flew to the location of Fengyue Lake, and saw that Fengyue Lake was only half the original size, and the original cold pool also became a hot pool, and the original hot pool was submerged by black rocks and disappeared.

Silently comparing the altitude of the water level of the hot pool in his heart, Feng Hua Xueye finally understood why the hot pool formed there in the Dugu Palace was only fifteen meters high, and it turned out that the two pools and the massive hot springs deep underground together formed a huge connector, so that the two hot pools gushing out of the ground reached the same altitude.

As for the reason why the cold spring, which was originally extremely cold, became a hot spring because of the lack of Xuanming cold qi, it is even simpler: at a depth of more than 10,000 meters underground, there is a lot of geothermal energy, and there is a magma layer next door, although the heat of the magma layer is really absorbed by the refining furnace, but it still makes the cold spring without the cold air of Xuanming become a hot spring.

After absorbing the Xuanming cold qi in the cold spring, after finishing his cultivation, when he felt that the surrounding spring water had turned into a warm hot spring, he guessed that the refining furnace might not have absorbed all the heat of the magma layer.

So at this time, he came back to the windy and snowy night above Fengyue Lake, and once again carried out earth escape, entering the area of the half of Fengyue Lake that turned into black rocks, and after escaping for nearly 10,000 meters, he found Shui Linglong, who was still cultivating on his knees.

At this moment, Shui Linglong is still cultivating, but the process of refining the black devil cold ice and fire has also reached the end stage, as long as there is another day or two, it can be completely over.

Fenghua Xueye used his spiritual power to investigate Shui Linglong's cultivation, and now there was no danger, so he continued to retreat to the earth, and walked more than 90,000 meters before he found the refining furnace.

In the course of this retreat, the wind and snowy night gradually appeared, and the originally fiery red and hot magma gradually turned dark red, then black and red, and finally turned into black solid rock, and the heat was completely lost.

The magma around the Refining Furnace had already turned into black rock, and only the magma layer farthest away from the Refining Furnace had not yet completely cooled down and turned into rock.

When Fenghua Xuexue fled here, he directly took back the refining furnace, and the remaining magma layers that had not been completely cooled accounted for only a few percent of the original, just leaving these to heat the hot springs thousands of kilometers away next door.

In this way, within a few years, the newly formed hot pools in Fengyue Lake and the Lonely Palace will never become ordinary pools, and will always remain above forty degrees.

After retracting the refining furnace, Fenghua Xueye returned to Shui Linglong's location again, realized the Dao again, and continued to temper his Dao foundation.

Three days later, Shui Linglong suddenly woke up, ending the process of refining the black devil's cold ice and fire that had lasted for several months and nearly half a year.

As soon as she woke up, the black fire enchantment that automatically came out of Shui Linglong's body surface was restrained and retracted, and she also fell directly for more than ten centimeters, falling on the black rock.

Shui Linglong tried her best to look around, but now it was pitch black, her true dragon eyes had a certain night vision, but in the depths of the underground without the slightest light, she could only see a rough idea.

She stood up in some panic, took two steps forward, and hit the rock on her forehead, and finally she groped around, and finally determined that the place she was in was a small spherical place about two meters in diameter, surrounded by cold black rocks.

Only then did Shui Linglong remember to release the blue thunder talisman qi, and with the help of the blue thunder light, she could finally see the place she was in clearly.

"Feng Lang, are you there?" Shui Linglong shouted after calming down completely.

But the voice echoed back and forth around, but there was no response from the wind and snowy night, and after half an hour, the echo in the spherical cave completely disappeared, which shows that the ability of this black rock to transmit sound waves is very poor, most of the sound waves bounce back, and then bounce around in the entire spherical cave, and it bounces back for half an hour before it completely dissipates.

Feeling this, Shui Linglong didn't dare to shout a second time, she thought that this sound would not be transmitted far at all, and if she shouted, it would be in vain, and she was planning to use her own ability to break through the black rock with all her might.

At this moment, because Shui Linglong has completely refined the black devil cold ice and fire, her strength realm has also been completely improved to the realm of the fourth-grade Fighting Demon Emperor, as long as she goes out to experience a thunder tribulation, then her dragon ball can also completely turn into a dragon baby and complete the final promotion process.

After Shui Linglong felt her own strength, she released her thunder fighting energy, and used the dragon clan's thunder fighting technique Thunder Dragon Penetration, attacking the black rock above her head with all her strength, but the black rock didn't move at all, and not even a single debris was broken.

Seeing such a result, Shui Linglong was a little dumbfounded, and wondered in her heart: "Is this rock so hard?" My strength is now also improving by leaps and bounds, even my strongest thunder fighting skill can't break a little rock, you must know that thunder is earth, but why is it useless now." “

"I don't believe in this evil anymore, I must break you to pieces and leave this hellish place. “

Shui Linglong was wondering, but also swore ruthlessly.

"Water Dragon Roaring Sky!"

Linglong shouted softly again, showing the dragon fighting skills of the water system, and the water dragon roared to the sky.

When the water system fighting energy dissipated, the rock was still intact, and this time Shui Linglong directly carried the water system fighting energy with his fist, and hit the rock hard, and suddenly there was a concentrated pain.

"Grandma, why is this hellish rock so hard, it hurts me to death. “

Shui Linglong held her right hand and cried out in the tone that occasionally burst out of the wind and snowy night.
