As the wind whistled past their ears, the two of them continued to fly forward.

There were many savage beasts in the Returning Ruins. However, this was only in comparison to its vast size. The real situation was to find a long distance in order to find one.

Roughly four hours had passed as they sped along the way.

Cang Yun and Cang Qing stopped in their tracks. Another savage Spiritual Beast appeared in their line of sight.

This was the fifth savage Spiritual Beast that Cang Yun and Zhou Chen had encountered in the past four hours.

However, because it was only the outer perimeter of the sea of fire, the savage Spiritual Beasts they encountered were all of low cultivation. They were all within the range of Rank 5 or Rank 6.

For Cang Yun, whose strength had greatly increased, this had no effect on him.

Thus, Cang Yun handed these spirit beasts over to Cang Yue to handle. Firstly, it was to enrich Cang Yue's battle experience. Secondly, Cang Yun could observe the approximate strength of these Savage Spirit Beasts from their battle.

This time, the one he met was a Rank 6 Savage Spirit Beast, Black Pine Tiger.

A Rank 6 Desolate Spirit Beast was equivalent to the sixth layer of cultivation that humans had. It was neither high nor low, and was most suitable for Cang Yue to practice with now.

Seeing this, Cang Yue did not hesitate at all.

Taking a step forward, she stroked her zither with her bare hands.

Clang!

In an instant, the sound of the zither rang out. A sound wave that contained Origin Energy transformed into a sound arc and cut towards the black pine tiger at lightning speed.

After going through the first few battles, Cang Yue's attacks now contained a trace of sharpness and decisiveness.

Bang!

"Roar!"

This attack ruthlessly struck onto the head of the Black Pine Tiger. With Cang Yue's current eighth layer cultivation, it was simply too late for the Black Pine Tiger to react due to the disparity in cultivation.

With a "peng" sound, the Black Pine Tiger's enormous body flew backwards.

Fresh blood splattered everywhere, and a bloody wound that was deep enough to see bone appeared on the Black Pine Tiger's head.

Ever since she awakened Clear Sound's Exquisite Body, Cang Yue's strength received a qualitative leap, and was completely comparable to those top geniuses. Adding on to that her cultivation had crushed them, so in a single strike, she dealt a heavy blow to Black Pine Tiger.

However, when he saw this, Cang Yun frowned slightly, "Your attack was still off by three points. It is not decisive and accurate enough."

Every time Cang Yun made a comment, he would point out the shortcomings for Cang Yue, hoping that the latter would be able to grow up the fastest.

For battle techniques, Cang Yue's comprehension ability was not weak, but she still lacked the determination to kill. For example, when she killed this Black Pine Tiger, Cang Yue clearly could have killed it with one strike, but in the end, she forcibly deviated several centimeters away from her weakness.

This was related to Cang Yue's personality, but Cang Yun still wanted to help his change. In a battle, there was no benevolence in saying that. Giving the opponent a chance, would only increase the danger for himself.

Cang Yue nodded, and her gaze gradually became sharp.

Clang!

The zither music rose up again, and another arc was slashed out, understanding the Black Pine Tiger's life.

As the two of them continued forward, they encountered all sorts of savage spirit beasts along the way.

"If your strength is insufficient, then the Conflagration Ape must focus on defense. Once you attack, you must increase your strength!"

"Its speed is too slow. The red snake is known for its speed. I have to keep up with its speed in order to hit its weakness!"

"…"

Cang Yue was still on her journey, and Cang Yun was on the other side commenting and giving pointers.

Gradually, the two of them went deeper and deeper into the sea of flames.

And after no less than twenty battles, the current Cang Yue had undergone a tremendous change. From her body, one could clearly sense a sharp aura that caused one's heart to palpitate.
