It can be said that the source of the entire secret realm and cave heaven and the support of the power rules all come from the source core.

The reason why the resources and spiritual materials in the secret realm cave heaven are so rich is largely related to the original spiritual energy emitted by the source core. They have been born one after another after 100,000 years, rather than deliberately left by Xu Xuan in his previous life.

Moreover, the power of the forbidden law in the cave heaven can be killed even if it is connected to the third level of the sky. The root of that power is also the source core.

From these things, it can be estimated that the source core contains such taboo power and original laws.

However, once the source core is removed, it will cause the collapse of the secret realm and cave heaven here.

Xu Xuanxian asked Chan Fuer and the white-robed clan leader to withdraw from the cave.

Soon, Xu Xuan was the only one left in the empty secret cave.

He took a deep breath, and the golden mark between his eyebrows moved a hint of terrifying and sudden electric patterns. He raised his hand and pointed to the depths of the lake that originally carried the Tianxuan Spiritual Liquid.

"Boom--"

In the extreme north of the universe's original realm, a shocking explosion suddenly came, and the void interface collapsed, and a catastrophic space taboo force erupted.

That power even shook the wastelands near the Origin Realm, turbulent and storms, and continuous surges.

The moment the source core was taken away, the secret realm of the previous life lost the support of the source of power and collapsed and disbanded.

Xu Xuan, who lived in it, was instantly submerged in the taboo power of the collapse of the space.

Although the space size of the secret realm and cave left in the previous life cannot be measured with the interface space, the backlash power generated during the collapse is comparable to the interface collapse.

If it were an ordinary emperor, he would not be able to escape death.

However, Xu Xuan, who was promoted to the fourth level of the Immortal Golden Body, stood in the deadly storm where the space collapsed, and was still calm.

Now, his golden body realm has surpassed the fourth level and is close to the peak of the fourth level.

With the power of the golden body alone, he can defeat the Emperor of the Origin Realm.

Swish!

When the storm was slightly stable, Xu Xuan disappeared from the Dead Domain Storm. Return to the Northern Ice Domain and meet with the Holy Clan leader and Chan Fuer.

Seeing Xu Xuan appearing unscathed, a trace of shock flashed in the white-robed clan leader's eyes.

The taboo backlash that erupted during the collapse of the cave sky in the secret realm. Even a peerless powerhouse like him in the late stage of Shenxu would be difficult to escape unstoppable.

After Xu Xuan appeared, he found that in the vicinity of the Northern Ice Domain, in addition to the white-robed clan leader, there were also some senior leaders of the Universe Holy Clan, including some powerful people such as the Universe Emperor.

"Word to the Emperor of God!"

The Emperor of the Universe and others stood on both sides and saluted Xu Xuan.

This situation shocked some of the peak powerhouses in the universe.

The universe has always been a transcendent force in the ten directions of the world, and the holy clan is its true dominant existence.

Back then, even with the ability of a "magic master", he could not conquer the universe.

But now, the arrogant and transcendent holy clan of the universe actually surrendered to Xu Xuan's men.

On that day, Xu Xuan went to the Holy Clan Mountain to accept the surrender of the Holy Clan in the Universe.

The senior master of the Holy Clan soon learned that Xu Xuan was the descendant of the "noble man" of the Holy Clan during the founding period.

With Xu Xuan's current strength level, at least comparable to the three great masters, he is indeed qualified to become the uncrowned king of the universe.

Before leaving the universe, Xu Xuan gave the patriarch the universe a jade slip.

This jade slip records the peerless magical powers that the ancestor of the universe once practiced. Back then, the ancestor of the Holy Clan even broke through the third level of Tongtian. After entering the ancient world, it was difficult to reverse and return to the outer world.

With this jade slip, the leader of the Universe broke through the third level of Tongtian, and had a great chance to start retreating with all his might.

"The original power and the origin law contained in the 'source core' can be unobstructed and allow him to break through the third level of Tongtian. Even the source core fragments near the source core can greatly increase the chance. However, now is not the time..."

Xu Xuan murmured in his heart, he had some plans.

Before being promoted to the fifth level of the Golden Body, Xu Xuan was worried that the leader of the Universe would break through the third level of Tongtian so quickly.

Of course, with the help of that jade slip, the patriarch of the Universe is expected to advance within two hundred years, but at least not so quickly.

Leaving the origin of the universe, Xu Xuan returns to the small fish world.

Next, he began to practice using the power of "source core".

The power of the source core comes from its original law power.

Among them, the original power is difficult to absorb and even more difficult to bear.

Xu Xuan, an ancient physical cultivation, has a strong body and can slowly absorb some original power. The cultivation of earth and gold is progressing rapidly.

At the same time, the original law in the source core was also absorbed by the mysterious vortex light ball deep in Xu Xuan's eyebrows, and grew stronger day by day under the spiritual will of the previous life.

In this case, Xu Xuan's body, cultivation, soul realm and even understanding will be improved in all aspects.

The source core contains the power of the simple origin of the universe, and its affinity with ancient physical cultivation is higher than that of later generations.

A blink of an eye.

Two years have passed.

On this day, Xu Xuan suddenly opened his eyes, put down the source core in his hand, and murmured: "Although the power of the source core is so close to the original source, as an ancient physical cultivation, everything is based on his own flesh and blood and people-oriented. If he is completely assimilated by this force, he will deviate from his true original path..."

At this time, the conversion rate of Xu Xuan's earth produced gold was close to the peak of the seventh level. After absorbing the source nuclear power, the immortal gold body gradually reached the peak of the fourth level.

In short, there are still four years left for the hundred-year agreement with Zong Rumo.

"The power of the source core can upgrade the small fish world to the original world, benefiting hundreds of millions of creatures and the water and soil, including yourself. Some source core fragments in your hands can even create a third-level cultivator of the Tongtian level. However, the power of the source core can increase your strength in the short term, but it is not suitable for you to be used in the long run."

The remnant soul of the previous life explained.

"I think so too. All the realms of ancient physical cultivation are dependent on myself."

Xu Xuan nodded.

Soon, he left Tianji Ancient City, found Chu Dong, Xu Huilan, and Zhang Feng, and discussed the final improvement plan for the Xiaoyu Realm.

This matter is limited to four people, becoming the highest secret of the Xingfeng Dynasty.

Half a month later, the four of them finally customized an unprecedentedly huge plan. In addition to Chu Dong's immortal performance, Xu Huilan's master-level formation skills, and secret guidance from the remnants of his previous life.

After the plan was successful, Xu Xuan first kept the source nuclear debris and distributed some source nuclear debris to the most important relatives and friends around him.

In addition, the nine treasures left behind will be integrated into each piece, with a source core fragment, and its potential level will reach at least a semi-immortal weapon...

After following these instructions, Xu Xuan began to practice in seclusion again and began to release the power of the "Immortal Demon Dragon Pill" for the second time.

The second release. The medicine is stronger, almost lifting Xu Xuan's immortal golden body to the limit of the fourth level.

At that moment, Xu Xuan could even faintly touch the more powerful fifth layer of the golden body.

It took half a year to absorb the medicinal power.

In the second half of the year, Xu Xuan and several women practiced the dual medical practice, and their overall cultivation level further increased.

"It seems that in the next two or three years, I will be promoted to the middle stage of Shenxu. The golden body will break through the fifth level and be sure of it."

Xu Xuan thought to himself.

Judging from his current strength, he can easily defeat the peerless power in the late stage of Shenxu.

If we look at the strength of Zong Rumo five or six years ago, Xu Xuan has at least 600% chance of winning.

But Xu Xuan could not predict how much progress Zong Rumo would make over the years.

In the next three years, Xu Xuan prepared to continue his retreat.

On one day, a news came to Xiaoyu Realm.

This news comes from the distant glorious world.

The person who came to report the news was Xuan Hun, the eldest disciple of the Shenhuan Heavenly Master.

"You mean... Yuyan has come out of seclusion?"

Xu Xuan was surprised and mixed with surprise.

"That's right. Junior Sister Yuyan spent 10 or 20 years in a mysterious dream and experienced incredible encounters. As soon as she came out of seclusion, her cultivation level was approaching Emperor Shenxu."

Xuan Rong said with a smile.

Upon hearing this news, Xu Xuan immediately rushed to the Origin Realm of Huangtian.

In about one or two months, Xu Xuan arrived at the Origin Realm.

Just as he reached this realm, a trace of darkness was generated in Xu Xuan's memory starry sea.

That kind of sensation comes from an unfinished emotional relationship in the previous life.

"How is this...Junior Sister Li's breath..."

The golden marks between Xu Xuan's eyebrows are beating frequently.

With a complex and incomprehensible mood, Xu Xuan came to Kongshan Liu Yu and met Liu Yuyan.

Liu Yuyan wore a white dress, without any makeup, and was as elegant as a fairy, lingering in the swaying mist like birds singing in the empty mountains, making her extraordinary.

Those beautiful and empty eyes, with three points of attachment, three points of resentment, three points of joy...
