The cave is winding and bottomless, and the further you go inside, the lower the temperature and the richer the aura.

Shisu was not surprised by this, because he had already felt the breath of ice spiritual power.

This undoubtedly shows that the attribute of this underground spiritual vein is ice.

Yu Feng and Long Xiangxiang both have good cultivation, although they are only wearing summer clothes, they can easily resist the lower and lower temperature in the cave.

However, as we went deeper, the temperature dropped sharply, reaching more than minus 30 degrees.

Yu Feng has the power of fire source, and he doesn't need to use his luck to resist this severe cold.

But Long Xiangxiang already felt a little cold, and had to quietly exercise to resist the cold.

Zi Su had taken the blood of the fire dragon, and he had not only cultivated the true qi of the dragon's blood and the spiritual power of the dragon's blood, but also possessed the power of the source of fire, and the temperature of minus thirty degrees was no problem for him.

In his heart, he felt very interesting that the purple giant snake was not afraid of the cold.

From a scientific point of view, snakes are very afraid of the cold, otherwise they would not have hibernate in winter.

But there are exceptions.

Shiso could feel that what this purple giant snake cultivated was ice spiritual power, which should be the reason why it was not afraid of cold, and it was the most important factor why it chose to entrench in this cave.

As she continued to move forward, Long Xiangxiang felt a chill on her body. At this time, Zi Su quickly took out her coat and put it on her, and grabbed her hand, and transmitted a fiery dragon blood true qi to her, which made her feel a lot more comfortable, especially Zi Su's gentleness and care, which made her very useful and sweet.

This made Yu Feng very envious, and couldn't help but say in a coquettish voice: "Su, you are so eccentric, why do you only care about Xiangxiang and don't care about me, people are also cold!"

This made Long Xiangxiang secretly amused, this Sister Fengfeng doesn't look old, but she looks like a little girl.

"Okay, okay, I care about you too. Zi Su naturally knew that Yu Feng just wanted to get the same treatment as Long Xiangxiang, so he immediately put a thick coat on her and took her hand, which made her smile.

The purple giant snake circled in front of them, and the three of them walked hand in hand, all of them had a kind of warmth in their hearts.

Led by the purple giant snake, after a quarter of an hour of advancement, the three of them finally arrived at its lair.

It's a huge underground cavern with a temperature of at least minus 50 degrees Celsius, and thick ice everywhere.

And the concentration of aura here has also reached its peak.

At this time, the Martial Dragon Ring in Shisu's body was running wildly, automatically absorbing this cold ice spiritual power, which made his spiritual power grow rapidly, and the spiritual power in the middle dantian became more and more intense.

Zi Su knew that only by making his spiritual power rich enough to liquefy could his spiritual cultivation break through to the realm of a spirit master.

The purple serpent soon came to the center of the cave, where there was a dragon-shaped spirit vein, constantly exuding an absolutely cold aura, which was why it was so cold here.

Shiso looked at it, the dragon-shaped spirit vein was not very large, showing the color of Xuan Bing, about 20 meters long and about half a meter wide, but the ice aura contained in the ground, including this, was very huge, if he could absorb it all, it would definitely be able to bring earth-shaking changes to his cultivation.

Yu Feng and Long Xiangxiang had never seen a spirit vein, and they couldn't help but be very curious when they saw it at this time.

Long Xiangxiang even wanted to step forward and touch it, but fortunately Zi Su reminded her in time, otherwise even if she was a miracle martial god, she might be frostbitten by the extremely low temperature.

Only a martial artist like him and Yu Feng who possessed fire attribute techniques, or a spirit who cultivated ice spiritual power like a purple giant snake, could resist this extremely cold intent of at least minus 100 degrees.

Suddenly, the purple giant snake coiled around the spiritual veins, as if reluctant to give up.

Shisu smiled, "Are you reluctant to leave here with me?" These words were said and transformed into a voice that the purple giant snake could understand.

The purple giant snake's lantern-like eyes shone on Shiso, and he nodded slightly: "I have been here for hundreds of spring and autumn seasons, and this is my home, and I am a little reluctant to leave all of a sudden." ”

The feelings of this snake are really as rich as a human, and Zi Su Waner smiled: "Then are you reluctant to give up this family, or are you reluctant to give up this dragon-shaped spirit vein?"

The purple giant snake said: "The main thing is that I am not willing to give up this spiritual vein, what can the master do to transfer it away?"

Zi Su groaned slightly, and said with a smile: "I don't have this ability to transfer now, after all, this spiritual vein may be rooted deep underground, but I can take some of these ice spiritual qi away for your cultivation in the future." ”

The purple serpent was very happy to hear this, "Really, that's just wonderful. ”

Since that was the case, Shisu naturally wanted to help it do it, so he immediately cast the dragon blood vortex to absorb this extremely cold ice aura.

When absorbing, Zi Su warned Yu Feng and Long Xiangxiang that no matter what they saw, they were not allowed to touch his body.

Automatic absorption and active absorption, the speed is completely different.

The rotation speed of the Martial Dragon Ring was ten times faster, and it was simply unbelievable.

Fortunately, thanks to the transformation function of the Martial Dragon Ring, otherwise, even if Shisu had taken the blood of the fire dragon and cultivated the fire source power and ice source power, I am afraid it would be difficult to resist so much ice aura entering the dantian at once.

Yu Feng and Long Xiangxiang both looked at Shisu a little nervously, only to see that the top of his head was quickly filled with an extremely cold Xuan Ice Qi, and a thick Xuan Ice began to form around him.

As the absorption continued, the ice around Shisu's body became thicker and thicker, and soon enveloped his entire body.

At this time, Zisu had already seemed to have become an iceman, and fortunately he had already reminded him, otherwise Yu Feng and Long Xiangxiang would really be so worried that they wanted to rescue him.

The purple serpent also stared intently at Shiso's slow transformation into an iceman, but it was not worried, and the color of respect appeared in its huge lantern-like eyes.

Whether the master is strong or not determines the growth height of the brute.

Seeing that Shiso could absorb the ice aura so quickly, the purple giant snake's heart became even more determined to follow.

If before it was only close to Shiso, now it has gradually made up its mind to follow him forever.

Don't look at Shisu's body wrapped in thick ice, but in fact, this is because he expels the cold qi from his body, and his body is not cold at all.

As more and more ice aura was transformed into dragon blood spiritual power and Zixia spiritual power, the two different properties of the middle dantian of the shiso, and the spiritual power of different colors gradually reached the critical point of liquefaction, which was a symbol of the imminent breakthrough.

The liquefaction of spiritual power is the sign of a spirit master, which is the same as the samurai to the martial artist realm, and it is also a process that requires the liquefaction of true qi.

With the crazy rotation of the Martial Dragon Ring, the spiritual power in the dantian in the shiso became more and more intense, and the pressure became more and more intense.

When the pressure reaches a certain level, it can liquefy spiritual power from a gaseous state into a substance like water.

As if with a bang, Shisu felt suddenly enlightened, the original pressure suddenly decreased, and the two spiritual powers in the middle dantian were all liquefied into liquid.
