For the great changes in Black Tooth City, Zhang Liang saw it in his heart.

He didn't interfere with anything, on the contrary, he also helped the Black Fang tribe a lot in this regard.

The Innate Realm Exercises in Black Tooth City were the exercises he had obtained from the Ji Clan's Western Mansion.

However, he modified the exercises of the innate realm obtained in the Ji Clan's Western Mansion to a certain extent.

Although the cultivation techniques that circulated among the Ji clan can be practiced to the innate realm, they basically have no potential for development in the later stage, and they have no ability to break through to the next realm at all.

Zhang Liang used the Wanyan Holy Technique to deduce and successfully improve the cultivation method, although he did not create the cultivation method of the Purple Mansion realm, but at least the potential of this exercise was greatly increased.

If it's used to build a foundation, it's pretty good.

It won't bring any mistakes or omissions to his cultivation career, and it is not too difficult to break through to the Purple Mansion realm with this exercise.

Even if you want to change to practice in the later stage, it won't have much impact on yourself.

But Zhang Liang can only do that, he has to complete his own business next.

In this land where gods and demons loom, the only thing that can give you the power to protect yourself is strength.

The only one who can rely on himself is nothing, and everything else is vain.

............

It is about a thousand miles south of Wanjian City, the city of Great Xia controlled by the Ji family, in an ordinary mountain forest.

Zhang Liang's figure suddenly appeared in it, dressed in a white robe, constantly fluttering under the strong wind, and he volleyed into the air, constantly observing the land.

Although this mountain forest did not show any peculiarities, judging from Zhang Liang's Yuantianshu attainments, he could feel the majestic earth qi under this land.

Judging from his exploration, this is a blessed land.

Under this land, a huge amount of Heaven and Earth Yuan Qi has gathered, and the Heaven and Earth Yuan Qi has been solidified, almost like the source in the Heaven Covering World.

According to the name of this world, this kind of thing similar to the source should be called Yuanshi.

And after Zhang Liang carefully explored the land, he determined that this was the place he was looking for.

Hidden beneath this land is a large town, so that the surrounding neighbors can't help but gather in this way.

But this large array is well hidden, and it will not make the people around him feel abnormal, even if they are standing on this earth, they will not be able to detect the huge heaven and earth aura here.

If it weren't for Zhang Liang's grasp of Yuan Tianshu to an extremely profound point, he wouldn't dare to make up his mind.

Naturally, there has never been a Book of Origin Heaven in this world, and there is no involvement in such top feng shui secret techniques as the direction of the earth's dragon veins, searching for the dragon's nest, and exploring the phoenix's nest.

Although the formation has almost reached its peak, there are still many loopholes for Yuan Tianshu to drill.

Zhang Liang kept wandering in this mountain forest, and kept sending out strange edges as he walked.

He used the strange cave exploration technique in the Book of Origin Heaven to find out how big this great array enveloped the entire earth really was.

The more he inquired, the more surprised Zhang Liang became, this strange array enveloped a range of more than four thousand miles.

And the depth has reached more than 300 miles, which is incredible in Zhang Liang's opinion.

Because judging from his induction alone, this large array is not very powerful, at most it plays the role of gathering the Heaven and Earth Yuan Qi and hiding the fluctuations of the aura.

It would not be too difficult for Zhang Liang to break this large array, he could directly use the earth dragon qi to make the entire earth fluctuate like a giant dragon turning over, and directly destroy this huge large array through the transformation of the terrain.

However, he did not act rashly, but cautiously probed.

He used the Origin Heaven Technique, his eyes were like two golden lamps, and he could easily see through the ground.

He could see that at a depth of a hundred miles above the ground, there was a stone chamber, in which a Taoist dressed in a fiery red robe and carrying three giant swords on his back was meditating on a stone bed.

With the breath of the Taoist, the endless aura of heaven and earth continued to pour into the stone room.

And that strange stone chamber had a unique formation on it, which could allow the Heaven and Earth Yuan Qi to gather in it and maintain an extremely high concentration.

Zhang Liang could see that the heaven and earth aura next to the Taoist had been liquefied and turned into a water-like existence, and the heaven and earth aura contained in it made Zhang Liang couldn't help but be stunned.

Such a liquefied ordinary aura is almost comparable to the source of the Heaven Covering World, and what is even more rare and valuable is that such a Heaven and Earth Yuan Qi, with the help of its formation, is almost endless.

This land is simply a holy place for cultivation.

And the Daoist in the stone chamber had obviously cultivated to a critical point, and the endless liquefied aura was constantly absorbed and refined by him.

The aura on the Daoist body is also constantly increasing, and according to the standards of this world, this Daoist has cultivated to the realm of the Yuan Shen.

Moreover, it is also the peak of the primordial god realm, and it is about to break through to the point of returning to the void.

It seems that the action should be to break through to the realm of returning to the void on this land.

According to Zhang Liang's speculation, it will take about ten years for this Taoist to break through to the realm of returning to the void.

After about ten years, this Daoist can truly break through to the realm of returning to the void, which is the so-called earth immortal in this world.

At that time, the heaven and earth aura gathered in this blessed land will not be of much use to that earth immortal, and it is estimated that he will leave here directly, and the strange heaven and earth array that envelops this place is estimated to be taken away.

Zhang Liang didn't want to wait for this Taoist to leave, he was occupying this blessed land.

That's taking too long.

Moreover, this Taoist did not make good use of this blessed land at all, and with the cognition of this world, they were completely unaware of such a blessed land.

In Zhang Liang's exploration with the Source Heavenly Book, there is a huge dragon vein in this land, and such a dragon vein has an incomparably huge effect on cultivation.

This Taoist was far from exerting the function of this blessed land, but only used it to gather the spiritual energy of heaven and earth.

In Zhang Liang's opinion, it is a pity, judging from Zhang Liang's Origin Heaven Technique detection, there is a majestic earth dragon qi under this land.

The dragon marrow has even been bred under the earth, and this kind of concentrated water bred by the dragon veins of the earth is extremely important for Zhang Liang's cultivation.

There is not much exploration of the secret art of feng shui in this world, so Zhang Liang, who has the Book of Yuantian, is almost a grandmaster-level figure in this world.

Zhang Liang didn't want to wait here, nor did he want to directly attack and kill that Taoist.

Although he is now considered a murderer, for some unrelated characters, Zhang Liang does not want them to be infected with blood.

The more he practiced, the more he paid attention to this.

Wanton and indiscriminate killing of innocents, that is the behavior of the demon king, Zhang Liang disdains it.
