In desperation, Nangong Yan rented a room nearby, and then asked his subordinates to investigate the collusion between Mu Wushuang and the people of the Taisheng Heavenly Palace.

However, if you want to find someone in the vast sea of people, you don't rely on strength alone.

After the people of the Northern Saint Family entered the True Martial Kingdom, they were unfamiliar with the life path here, and there were only dozens of them, so it was impossible for them to run all over the True Martial Kingdom to find Mu Wushuang.

What's more, whether Mu Wushuang is in the True Martial Kingdom now is still the same thing.

For them, it's like looking for a needle in a haystack.

Therefore, they can only pin their hopes on the purple guards.

On the other hand, Xu Tianhai returned to the Overlord Academy.

He knew that it was unknown when Nangong Yan would be able to find Mu Wushuang.

Moreover, even if she did find Mu Wushuang, she could have sent her men out and captured him back.

After returning to the Bahuang Academy, Xu Tianhai began to retreat.

After a few days of precipitation, he found that he finally sensed that there were signs of a breakthrough in the Yuan Force in his body, so he devoted himself to retreat, striving to break through as soon as possible.

At this point, his heart was at suffocation.

Three days later, the Kunpeng Ning Pill in the depths of his Yuan Sea released a golden light again, and, in that golden light, released a faint power of rules.

The power of this rule is finer than dust.

But if it is mastered, and triggered, then it can erupt with a force that is enough to destroy the world.

Xu Tianhai felt that his body was shrouded in the sun, and his whole body had a feeling of warmth.

Before, he had learned the Divine Seal of Breaking Force that Yi Qingya had taught him, allowing him to comprehend some rule powers in advance.

Although he didn't have much rule power at his disposal now, it was enough to take his comprehension to a whole new level.

As time passed, the power of various rules began to act on Xu Tianhai.

Among them, there is the power of space rules, the power of time rules, the power of reincarnation rules, and the power of life and death rules.

For a martial artist, it is very difficult to grasp the power of these fleeting rules.

Among the 10,000 warriors, there may not be a single warrior who can capture the power of one of the rules.

It's one thing to be able to capture the power of the rules, but it's another thing to be able to comprehend the power of the rules.

When a warrior captures the power of the rules, he will 'seal' it in the Ning Dan and leave it for later to slowly comprehend.

Xu Tianhai was already in the early stage of Ning Dan's cultivation, and once he captured the power of the rules, he could 'seal' it in Ning Dan.

Now Xu Tianhai has entered a state of mystery and mystery, it can be said that he has now entered a state of epiphany.

In his mind, he quickly flashed his past life and present life, and this kind of rapid flooding made him feel that his life was short, and that his past life and this life were like a dream.

He even felt as if he had seen the judges and Meng Po in the underworld, they were amiable and harmless to humans and animals.

In the underworld, there are also other ghosts such as bulls and horses.

They looked hideous, but he didn't have the slightest sense of fear.

In his opinion, he is like the master of the underworld.

In a daze, he saw the word reincarnation appear in front of him.

Those two words are engraved on a stone tablet, which is simple and vicissitudes.

His body walked towards the stone tablet step by step, and he instinctively wanted to refuse, but he found that he had no control over his body at all.

Finally, he finally touched his right hand to the stone tablet in front of him.

Almost at the same time, he felt a strong paralyzing sensation all over his body.

The next moment, he came to his senses.

"It hurts!"

He thought he was hallucinating, but when he opened his eyes, he saw that his right hand was as if he had been struck by lightning, and that small stripes of lightning appeared on his arm like lightning.

"Isn't what I just saw a hallucination?"

Xu Tianhai carefully checked his right hand, and suddenly his heart jumped.

He was tempted to figure out what had gone wrong with him, but after thinking about it for a while, there was no clue.

"I felt like I was in a dream just now, but these lightning streaks on my right arm now tell me that I wasn't dreaming!"

Seeing that his right arm had become weird, he gasped.

He hurriedly used his Yuan Force, trying to expel those lightning streaks on his right arm from his right arm.

However, as soon as he used his Yuan Force, he saw those lightning streaks on his right arm disappear in an instant.

"Is it a hallucination?"

As soon as he was puzzled, the next moment, he sensed a small force of rules entering his Ning Dan.

When his divine sense entered the Ning Dan, he found that some tiny luminous bodies had appeared inside his Ning Dan.

"It seems that I should have captured some rule power, but what rule power did I capture just now?"

His divine sense entered the Ning Dan and carefully examined the tiny luminous bodies.

However, he probed for a while, but in the end found nothing.

In desperation, he had no choice but to give up.

"It seems that I'll see what kind of rule power they are when I have time later!"

Xu Tianhai exhaled a breath of turbidity, closed his eyes, and continued to retreat and cultivate.

For some reason, he felt that his state of mind at this time was very different from before.

Before, after he entered retreat, his memories would flash back from time to time from some events in his past life.

But now, he will never flash anything from his previous life again.

He felt as if he had completely forgotten his previous life, which was so far away from him, that he even felt that his previous life was just a dream.

He felt that he should pay more attention to this life, and only this life was all he had.

"It seems that I have forgotten my past life, whether it is or not!"

Xu Tianhai sighed and said.

After entering the retreat, Xu Tianhai once again entered a state of mystery and mystery.

He didn't notice that the Ning Dan under his Yuan Sea was releasing golden light again, and those golden rays of light quickly nourished the tiny luminous bodies in the Ning Dan, making them gradually become dazzling.

In the end, all those luminous bodies escaped from his body and rushed into the Gathering Spirit Heavenly Array in front of him.

In less than ten breaths, those luminous bodies rushed into the interior of the Spirit Gathering Heavenly Array.

Everywhere it went, the aura around it would be devoured by it to the point that there was not even a scum left.

In less than a moment, they rushed into the depths of the leylines, devouring all the aura inside.

The Gathering Spirit Heavenly Array of the Overlord Academy was arranged by the powerhouses of the Dao Heaven Realm, and the spiritual energy stored in it was enough for ten thousand Ning Dan Realm martial artists to cultivate for a month at the same time.

However, those stored auras were now devoured by those luminaries in an instant.

Those luminous bodies quickly returned to the Ning Dan inside Xu Tianhai's body, and they became even more dazzling.
