Ou Yangming opened the jade box slowly, then a peculiar luster was instantly emitted from the inside.

His vision became blurry because his consciousness had entered another wonderful world due to the luster.

It was a world that could not be described with words. In the world, his physical quality achievements such as Power, Agility, and Physique turned to nothing because the only power that could exist was mental power.

Nobody explained to Ou Yangming, but he somehow had the knowledge when he entered the world.

This was the real Land of Inheritance, whereas the small ravine outside that was filled with strange air was simply a disguise.

Nonetheless, while the real land was wonderful, in terms of actual effect, it could not be compared with the small ravine outside.

This was because cultivating in the ravine was highly beneficial toward one's martial arts. Whether it was an inexperienced person who was new to martial arts or a Supreme Great Ancestor like Ni Xuetian, one could greatly benefit from the cultivation.

On the other hand, mental power was required for one to enter the wonderful world. How many people in the Ni family, or even the whole prefecture, possessed mental power and could release it?

After inspecting the world for a while more, Ou Yangming realized something ridiculous.

He found out that the Ni family's ancestor had actually set up a restriction in the world where even if one had mental power, as long as one did not carry the Ni family's bloodline, one could not enter.

As for how Ou Yangming managed to enter it… The only probable explanation was his mental power points.

Once his mental power was at a certain level, the restriction was non-existent for him.

It was just like how a baby could not climb a slightly higher step even if the baby had the strength of nine bulls and two tigers, but what if an adult had climbed it? An adult could easily climb the step by lifting his or her leg.

Needless to say, there was not such a huge disparity between Ou Yangming and the restriction.

After absorbing energy from the Black Magic Crawler king's flesh and blood where his mental power improved to a new height, his mental power happened to have surpassed the restriction limit, which was why he could enter the mysterious world.

Ou Yangming did not know whether to laugh or to cry when he understood everything.

'I'm truly very lucky.'

In the Land of Inheritance inside the spiritual world, colorful lights were emitted.

Each light represented one inheritance, and there were probably more than 10,000 of them in total.

After seeing the large-scaled Inheritance Lights, Ou Yangming's face changed. He instantly understood that the Ni family was not as simple as it seemed on the surface, and the wonderful spiritual inheritance was probably not something that could be achieved by a Supreme Great Ancestor.

Ou Yangming decided on a small thought after hesitating for a while.

Since he had gone so deep into the ravine, he could not leave empty-handed.

Nevertheless, Ou Yangming did not want to offend the Ni family completely, hence he purposely avoided those related to martial arts when he searched the lights.

A clan's grasp in martial arts was unquestionably the most obvious thing. If Ou Yangming accidentally saw a mysterious technique and unexpectedly learned it, he would not be able to explain himself no matter what.

On the other hand, no matter how cautious one clan was, strange skills were more likely to be leaked due to various reasons.

Smithing, medicine production, formation map, high-level appraisal art…

Plenty of information flashed in Ou Yangming's mind, which was too much for his eyes to take in.

Of course, Ou Yangming knew that he could not stay in the environment forever, and he had not come for the inheritance. Therefore, after briefly browsing the options, he decided on smithing and magic art.

Smithing was a straightforward choice because it was his survival skill, and he was not going to miss the opportunity of learning something more advanced.

As for magic art, Ou Yangming had decided on it because he noticed two words.

Mental power.

Yes, the magic art was a skill developed using mental power as the foundation.

After witnessing through the thoroughly meticulous state the big yellow dog's breathing, Ou Yangming was extremely interested in its gifted skill. He knew that if he used mental power correctly, he might also be able to release the same might.

Hence, after seeing the words 'mental power', his conception was attracted to it like a magnet, and he could not let go of it.

Time kept ticking away as Ou Yangming fathomed knowledge from the spiritual world in detail. After an unknown period of time, he suddenly experienced a splitting headache.

Next, he was distracted and had left the odd spiritual world.

"Ouch!" Ou Yangming squatted and put down the box. He grimaced in pain while holding his head, and was close to rolling on the ground.

He immediately understood that it was because he had over-consumed his mental power.

Mental power was constantly consumed when he stayed in the spiritual world.

If Ou Yangming was part of the Ni family, he would naturally be taken care of where he would be alerted in advance. However, since Ou Yangming had forcefully entered the world, he was not treated that way.

He wanted very badly to encounter a bunch of dead Black Magic Crawlers at that moment because he could compensate for the consumption by slaughtering them.

"Woof!"

The big yellow dog's bark was heard at the door all of a sudden.

Ou Yangming was stunned. He quickly covered the box as it contained a clear jade bead, which was the source of the mysterious light. Once he closed the box, everything became normal as though nothing ever happened.

If he had not experienced the immense pain that gave him the urge to crash into a wall and had not gained extra knowledge in his head, he might actually think that everything was just a dream.

Ou Yangming flashed to leave the cottage.

The big yellow dog had gotten up from the stretcher, but it seemed different from how it was before.

Although its outer appearance remained the same, its temperament underwent drastic changes. Ou Yangming felt an enormous pressure when the big yellow dog simply stood in front of him.

He blurted when a thought crossed his mind, "Supreme Great Ancestor?"

The big yellow dog exerted force through its legs to jump, and it transformed into a yellow light to arrive next to Ou Yangming.

If Ou Yangming's mental power was still as powerful as before, he could naturally sense everything clearly by entering the thoroughly meticulous state. He only felt something chilly beside him at that moment, then the big yellow dog appeared and licked his hand in a friendly manner several times.

Ou Yangming smiled bitterly. He wanted to rub its head, but he stopped halfway.

'I'm actually going to caress a Supreme Great Ancestor's head, am I out of my mind…'

That said, the big yellow dog quickly noticed his move, and it actually moved its head to his palm to rub against it.

Ou Yangming could not help but laugh. He went with it and placed his hand on the dog's head.

"Ah, I can't believe that you've become a Supreme Great Ancestor even though we came in together." Ou Yangming lamented. "I've only advanced one class, which is far from what you've achieved."

The big yellow dog tilted its head and cast a disdainful look at him to expose his lie.

Indeed, in terms of mere cultivation base, Ou Yangming and the big yellow dog were Heaven and Earth apart as the former was in Yin Grade Class Two while the latter was in Extreme Grade. Nonetheless, even the dog scorned at Ou Yangming when he said that he had only advanced one class.

It was worth noting that mental power upgrade was much more difficult than essential Qi improvement, and Ou Yangming's mental power had actually highly benefited.

Obviously, what the big yellow dog truly envied was the fact that Ou Yangming's potential burst out when he was on the verge of death, and he progressed from the integration of Heaven and man to the thoroughly meticulous state.

The apprehension of Heaven and Earth's path was tougher than mental power cultivation.

Many Supreme Great Ancestors had put in their utmost effort to arrive at Extreme Grade, but could not fathom the mysteries between Heaven and Earth, so they could not achieve the integration of Heaven and man, let alone the thoroughly meticulous state.

In comparison, the big yellow dog's mere power and its breakthrough in Blood Meridian were not worth mentioning.

Ou Yangming grinned and ignored the big yellow dog's look. He said, "Big Yellow, we've found the Land of Inheritance and the inheritance that they need. What about the Life-prolonging Golden Pill? Where's that thing?"

The big yellow dog blinked. It instantly understood what Ou Yangming meant.

Even though it was part of the Ni family, it had traveled together with and fought alongside Ou Yangming. It was true that they trusted each other with their life.

The big yellow dog hung its head and no longer showed the aura of a Supreme Great Ancestor.

Ou Yangming sighed. "Big Yellow, I'll never beg you for anything else, but I must save Old Craftsman. No matter what it costs, even if I have to risk universal condemnation, I… I don't care!"

He did not speak in a high tone, and the words were said so calmly that they did not sound threatening at all.

Despite that, just like he said, he did not care.

The attitude that he displayed frightened the big yellow dog, which had become a Supreme Great Ancestor.

It suddenly looked up deeply at Ou Yangming, then turned to enter the cottage.

Ou Yangming's eyelids twitched. He immediately figured that there had to be something else in there, but he was so immersed in the spiritual world earlier that he did not notice it.

Nevertheless, it would be inappropriate for him to enter the cottage again.

The big yellow dog came out after a brief moment, and it held a jade bottle in its mouth.

Ou Yangming was so excited that he began breathing quickly. There was no need for him to ask because the feeling transmitted through their spiritual connection was clearly telling him what was inside the bottle.
