The backyard is a large garden, dotted with a variety of rare and gorgeous flowers, and there is a sense of a hundred flowers.

Because of the geothermal soul guide system laid in the underground, the temperature here is always maintained within a constant range, and it is not affected by the cold climate here in Dragon City, it is warm and comfortable. You can even see many iconic plants and flowers that only grow in the southern part of the continent.

Yu Nanyuan looked around, the gentle smile on his face had long since subsided, and there was no trace of emotional fluctuations in his indifferent eyes.

Yebo stood quietly behind Yu Nanyuan, a look of nostalgia appeared on his face, and he said softly: "Miss used to like this place very much. ”

"Yebo, where is that ancestral land?" After pondering for a long time, Yu Nanyuan turned his back to Yebo and said expressionlessly.

Although Yu Nanyuan's tone was very calm, Yebo still noticed Yu Nanyuan's strong emotional fluctuations that were suppressed in the depths of his heart. He sighed softly, wordlessly went to a well in the middle of the backyard, and reached out and pressed a small hidden bump on the edge of the well.

"Buzz—" The ground began to tremble slightly, and the surface of the water inside the well was rapidly falling. The well water is cold and the temperature is at least below freezing. And after the well water fell, the chill became more and more intense.

"Nan Yuan, your grandfather told me about you before. However, the situation of the ancestral land of Dilongmen is relatively special, so I'll take you down to see it first. ”

Between the words, Yebo released his martial spirit. A layer of fine black scales was quietly dense, and his whole body was covered with a pitch-black halo, and the light in the surrounding space seemed to be swallowed and dimmed.

Two yellow, three purple, and five soul rings also rose from Yebo's feet.

His martial soul is called the Night Dragon, which is a dark attribute earth dragon martial spirit. Although it is not as powerful as Wang Jinxi's Bone Dragon King, it can also be regarded as a relatively high-level martial spirit. It should be said that any martial soul related to the dragon clan will not be too weak.

Yebo grabbed one of Yu Nanyuan's wrists, and then his figure fluttered towards the well with Yu Nanyuan. The depth of the well was about 30 meters, and soon the two of them came to the bottom of the well.

The stone wall at the bottom of the well is cold and slippery, and one side of the stone wall has a clear diamond-shaped indentation.

Yebo Zhengse said: "This is the entrance." ”

"Hmm." Yu Nanyuan responded, and without saying anything, he directly embedded the 10,000-year-old rouge dragon crystal on his chest. The pink light flickered, and then the light marks spread out in all directions around this 10,000-year-old rouge dragon crystal, forming a complex pattern.

"Zazazaza—"

Immediately afterward, the entire stone wall trembled to open to the sides, revealing a portal that could only be penetrated by one person.

Strangely, when this portal was opened, a large number of cold snaps poured out of it. This terrifying low-temperature environment made Yu Nanyuan even feel like he was using his soul technique in the face of Wu Changkong.

Yu Nanyuan subconsciously mobilized his soul power to resist this chill. At this moment, he was suddenly surprised to find that the speed of the soul power in his body had almost doubled in the process. Moreover, the soul power is still being tempered by this special chill, becoming more condensed.

When Yu Nanyuan and Yebo entered this cave one after another, a soft soul guide light lit up by itself. The situation in the entire cave was suddenly clearly presented in Yu Nanyuan's eyes.

The cave itself is not very large, but the surface is covered with a layer of dark blue crystals. Under the illumination of the soul guide light, thousands of halos are scattered, and there is a kind of beauty that is almost like a fantasy.

Yu Nanyuan stretched out his right hand and touched the layer of dark blue crystals, and a piercing chill immediately invaded his palm. However, with the barrier of his own soul power, these chills could not cause damage to his body for the time being.

Through the memories of his previous life, Yu Nanyuan knew that the Ice Pole Divine Crystal contained in this cave had been taken away by Huo Yuhao ten thousand years ago. These dark blue crystals in front of him shouldn't be Ice Polar Divine Crystals.

And it didn't take long for him to make a judgment.

This seems to be a special existence between rare metals and ice crystals, and already has some rare metal properties. It's a pity that these dark blue crystals have not been formed for a long time, and they can't be used as real rare metals to make soul guides, mechas, or fighting armor.

"According to the secret records left by the ancestors of the Earth Dragon Gate, these crystals were formed after tomorrow. Perhaps, after a long period of evolution, they will have some supernatural abilities. Ye Bo explained at the right time: "Those chills are overflowing from these crystals, which can have the effect of refining soul power and speeding up the cultivation speed of soul masters. After all these years of accumulation, it should be enough to support Nan Yuanling to break through the bottleneck of level 30. ”

Speaking of this, his expression couldn't help but feel a little emotional. Back then, Yu Nanyuan's mother, Nan Xi, had been cultivating here for a period of time, and he was also here at that time. I never thought that so many years had passed in a flash.

Yu Nanyuan's brows furrowed slightly, there was a certain discrepancy between Yebo's words and the information he had learned from his memories in his previous life.

Didn't Huo Yuhao say that this ice cave had entered a period of decay? How is it that after 10,000 years, instead of dissolving, those special dark blue crystals have been derived here?

If those Ten Thousand Years of Ice Essence hadn't been taken away, it would be very likely that these dark blue crystals had evolved into Ice Polar Divine Crystals.

However, Yu Nanyuan didn't dwell too much on these issues, his main purpose of coming here this time was just to break through the bottleneck of level 30. Taking a deep breath and pushing the thoughts out of his mind, he turned to look at Yebo.

"Uncle Ye, I'm going to stay here for retreat and cultivation from today onwards, and I'll trouble you with other things."

Facing Yu Nanyuan's firm gaze, Yebo smiled and nodded slowly.

"Okay, leave it to me. On your grandfather's side, I'll talk to him too. ”

……

On that day, Yu Nanyuan personally experienced the true effect of cultivating in this ice cave. It was just a cycle of the Great Zhou Tian, and the soul power in his body had been significantly improved. While the soul power is compressed and refined, the toughness of the body's meridians and bones has also been improved to a certain extent.

The soul power was running one after another in the body, and Yu Nanyuan had completely forgotten the passage of time in the outside world.

The cold air in the ice cave was squeezing his own potential. This time he was lucky enough to enter a state of deep meditation.

Without any changes, Yu Nanyuan successfully broke through the bottleneck of level 30 after his meditation cultivation was over.
