For the next period of time, Jiang Cheng lived in Dongzhu Island.

After the divine body was transformed into a turbid body by turbid qi, he hadn't practiced the Qing Qi system for a long time.

But now that it was rare to calm down, he also clicked on the long-lost system skill panel.

After so many years, the number of his profound crystals has also continued to increase.

Especially during the time of Tianfengshi, the origin of the world can be borrowed directly, and there is nothing you want.

Now the number of his profound crystals has exceeded 100 billion, reaching more than 130 billion.

"Although it is very inconvenient for the turbid body to use the immortal power and the profound pattern, but if you improve it, you will be able to use it sooner or later."

When he upgraded his skills last time, he raised the 1200 profound patterns to 18 levels.

Looking at it now, the remaining 1,800 profound patterns have also automatically broken through to the seventeenth level with the passage of time, and the progress bar has even passed halfway.

The reason why it can be so fast, apart from the automatic accumulation of time, the biggest reason is to play the way of heaven on the road of flowing gold.

That experience is not in vain, in fact, it is extremely precious and important.

Controlling a plane with the identity of Heavenly Dao, and constantly solving endless problems, his understanding of Dao and rules naturally improved by leaps and bounds.

He produced Daoyuan and was promoted to the Old Sage at that time.

Xuan Wen also made great progress during that period.

What's more, at that time, every time he passed a level, he could get a "level clearance reward", and his inner world was constantly evolving.

So this virtually saved him a lot of profound crystals.

"Should I raise a part of the profound pattern to the nineteenth level, or level it up to the eighteenth level as a whole?"

So far, the only person in Jiang Cheng who has seen the nineteenth-fold rule, and that is Yi.

In that Battle of the Immortal Mountain, he didn't need to use any source technique at all, and directly killed a group of descendants.

But after thinking about it again and again, he still decided to level the three thousand profound patterns to eighteen levels as a whole.

Because the three thousand heavy source technique seems to have a special effect.

It didn't cost too much profound crystals to upgrade the 1800 gates of the seventeenth level of black patterns, which had already been raised by more than half, to the eighteenth level. About 1.5 billion was enough.

This time, his Dao heart did not appear unstable.

Because he is already an ancient sage, with a source of Dao heart, he can completely maintain a balance with this level of Xuanwen.

The profound patterns of the three thousand gates and eighteen levels also strengthened his inner world again, making it even more powerful.

But in order to perform the three thousand heavy source technique, the system's "rule of rules" must also be raised to three thousand levels.

This thing only needs a few mysterious crystals in the early stage, and then it will be upgraded step by step. After reaching the thousandth floor, it will start to be a bit scary, and it is a big item that consumes mysterious crystals.

Jiang Cheng originally thought that three or four billion profound crystals would be more than enough, but in the end, he used five billion, which was two hundred floors short of full.

"Isn't this too pitiful?"

You know, Xuan Jing is very valuable.

He killed so many ancient sages and righteous gods before, and collected so many spoils of war. It can be said that he used the power of the top powerhouses in the Yuanxian world, but in the end he only collected less than 10 billion.

If it weren't for the experience of Tianfengshi, maybe there would never be a chance to make up the number in this life.

Having already chosen this path, he can only bite the bullet and continue.

The last two hundred floors cost him a total of 60 billion profound crystals, and the way of rules finally reached three thousand floors.

At the moment when the third thousandth floor was full, the system prompt sounded.

"Ding! The host's skill of the way of rules has successfully reached perfection, and he will be rewarded—the source of rules."

When he heard the last word, Jiang Cheng's jaw almost couldn't close.

"What the hell?"

"The source of the rules?"

"Isn't this reward too luxurious?"

"The system, you are so generous all of a sudden, it makes me feel uncomfortable!"

It's not my fault that he reacted so strongly, but this matter was too outrageous.

The Dao heart of the human race can become the source, the heavenly soul of the soul race can become the source, the spiritual will of the heavenly race can also become the source, and the monster race can even become the source of blood.

As long as it is related to cultivation, there are ways to enter the ancient sages.

Naturally, some of them are directly sourced from rules.

To be honest, the cultivation system of the disciples of the Feixian Sect is a direct path to the source of rules, but no matter Ji Linghan, Lin Ning, or Cang Ling Miao Yu, they are all just a source of rules.

After becoming an Old Sage, Ji Linghan's Rules of Ice can actually be regarded as a weakened version of the Origin of Ice.

This is not surprising.

It's just that Jiang Cheng has a lot of rules, a total of 3,000 rules.

His rule of becoming a source means that all three thousand profound patterns will become a source, which is not a normal thing.

"Having two sources can stabilize ordinary Old Sages."

"I suddenly have 3,000 more sources, wouldn't that be a second?"

The system acted swiftly and resolutely, and the next moment, three thousand beams of starlight lit up in his internal body.

The three thousand profound patterns seem to have been sublimated suddenly, and they all become dazzling, like stars, revealing the brilliance of divinity.

It is obviously still the eighteenth layer of Xuanwen, but it is already fundamentally different from before.

Each one seems to be endowed with a special vitality.

Jiang Cheng even had an intuition that even if he really died completely, they could still continue to exist.

Three thousand profound patterns formed at the same time, which also brought huge changes to his inner world.

If the internal body world is regarded as a plane, then its scope has not expanded much.

But the level of the plane does not know how many levels have been raised.

It's also fortunate that Jiang Cheng already had a source of Dao heart before, otherwise he would not be able to carry such a vast and huge source of power.

When all the dust settled, Jiang Cheng felt that the world inside his body was about to lose control, and he couldn't grasp it.

The original comprehension of the rules has become the 3,000 sources, as if there are 3,000 more individuals, he needs a long period of adaptation and coordination.

But the benefits are also obvious, his strength has been greatly improved.

In the future, even if it is an ordinary rule collision, he can easily crush others with the same level of rules.

But on the other hand, he did not ascend to the ancient sage three thousand times as imagined.

This is also a matter of course.

First of all, the Primordial Immortal Realm cannot accommodate creatures of that level.

And the three thousand profound patterns all belong to the system of rules, all of them come from one source, and they are essentially one source.

It's just that all the three thousand rules have become the source, which also means that his source is much more complete, solid and broader than Ji Linghan, Cang Ling and others.

After Xuanwen clicked, he looked at the soul panel again.

Still at the soul level, 100% progress, failed to cross to the next level.

That time in the Tianfeng Stone, after the Enlightenment Immortal Tree entered the origin of the world, his soul and spirituality had the opportunity to transform, and now they are also evolving a little bit.

"When the soul and spirit will also become the source in the future, how strong it will be!"

For the first time, this brother felt invincible without relying on the system.
