Chapter 1531

Gu Hanyuan needed a way that could threaten the Nine Heavens Mysterious Maiden's soul fragment without destroying her directly.

Either wait for the day the system rewards him with a divine artifact that could affect the primordial spirit of immortals and gods.

Or upgrade the "Myriad Phenomena Yin-Yang Art" again.

Waiting for system rewards might not be hopeless; after all, even the Divine Stone and the Kongtong Seal had appeared.

But that was full of uncertainty.

The most reliable way was to upgrade his cultivation technique again.

And this time, it would focus on improving his spirit and soul.

Gu Hanyuan had long had this idea, and now it was just more certain.

The "Myriad Phenomena Yin-Yang Art" focused on the harmony of Yin and Yang and spiritual power, and did not involve spiritual cultivation.

Strictly speaking, Wu Xingyun being invaded by the Nine Heavens Mysterious Maiden's soul fragment when her figure became large was also the fault of the "Myriad Phenomena Yin-Yang Art."

When the figure changed, the primordial spirit was not adjusted synchronously, and the density of spiritual power naturally decreased.

In fact, Wu Xingyun's strength was reduced when she became large; only when she maintained her petite figure was she at her peak strength.

That was why she could be so sturdy when facing Gu Hanyuan and not be broken.

Merging cultivation techniques was imperative.

There were quite a few cultivation techniques that could be used as fusion materials.

The complete "Heaven and Earth Yin-Yang Great Sorrow Scripture" was one of them.

However, the main spiritual cultivation technique was a bit difficult to handle.

Gu Hanyuan either had to get the "Dao Heart Demon-Seeding Technique" or choose one from the system.

Gu Hanyuan had his eye on a cultivation technique in the system.

That cultivation technique belonged to the Xianxia world, and its effect was even stronger than the "Dao Heart Demon-Seeding Technique."

But the price was also prohibitively high.

Fortunately, there were many charming women in this world, and the villain points obtained might not be enough to exchange for that cultivation technique.

And Gu Hanyuan also learned from Wu Xingyun about the world's will targeting her when she broke through to the Earth Immortal realm.

From now on, anyone who broke through to the Earth Immortal realm would have a great possibility of becoming an enemy.

Even those veteran Earth Immortals might not necessarily not be his enemies.

The spiritual energy of this world was recovering.

Breakthroughs in realms would become easier and easier, and the means of the world's will might become stronger and stronger.

It was not impossible for it to directly bewitch all Earth Immortals to attack him.

Gu Hanyuan immediately felt the situation was severe and needed to speed up his pace.

He spat out a breath of turbid air feeling refreshed, and instructed Shuang'er, who was wiping the corners of his lips:

"I leave Yun'er to your care, Shuang'er."

Shuang'er agreed with a blushing face.

Gu Hanyuan got dressed and washed up under her service.

His figure flashed and he arrived at Wen Tailai's guest room.

He looked at Wen Tailai, who was breathing evenly but unconscious, smiled playfully, and pushed the door out.

What met his eyes was the haggard and exhausted beautiful wife, Luo Bing.

He said regretfully in her expectant gaze:

"Mistress, I have done my best." ===== CHAPTER 1533 =====
