Lu Yun came directly to Jin Canhua, and the small lake immediately began to roll, and a one-meter-long crocodile rushed out of the water, and its tail swept directly towards Lu Yun.

Lu Yun dodged away and found that this crocodile had turned into a demon beast and had its own spiritual intelligence, but the crocodile's strength was not strong, it was only the seventh level of the Dragon and Tiger Realm.

This is probably the reason why there is only this crocodile nearby, after all, it is one point stronger than other demon beasts.

He was no longer polite, and with a movement in his heart, the Xuanyuan Sword flew out and turned into a broad sword.

Lu Yun injected true qi, and the Xuanyuan Sword was like a resurrection, exuding terrifying killing intent.

The crocodile was about to open its mouth to bite it, but its body suddenly stiffened, shocked by this killing intent.

Xuanyuan's sword slashed down and slashed past the crocodile's back, directly cutting the crocodile in half.

The crocodile was in pain, and its two bodies began to roll wildly, directly into the small lake.

In an instant, the water of the small lake was dyed red, and after a while, there was no movement in the water.

Lu Yun leaned out of his spirit and found that this demon beast crocodile had been killed by him, and at the same time, he was also amazed at how powerful the Xuanyuan Sword was activated, it was very sharp, and it also had a deterrent effect.

He came to Jin Canhua, unceremoniously pulled it all out, and found a place to start taking it.

These nine golden canflowers are all strengthened spirits, and the nine plants are under the belly, and Lu Yun's spirit is strengthened again, and it is not far from the eightfold realm of the imperial realm.

Next, he found a dry place and simply built a straw hut for the next period of living.

Sitting cross-legged in the grass hut, Lu Yun began to cultivate.

As soon as he ran the exercises, Lu Yun was pleasantly surprised, the cultivation effect here was excellent, far beyond his imagination.

The cultivation speed here is dozens of times that of Chang'an City, which can allow him to quickly improve his cultivation, and then, Lu Yun fell into a crazy cultivation.

Of course, it's not safe here, so he keeps it every time, and doesn't make himself tired like at home.

Even so, the results of his cultivation were very amazing, and the breathing method was really against the sky, constantly turning the aura into true qi and spirit, so that his strength continued to improve.

Half a month passed in the blink of an eye, and Lu Yun's strength realm finally broke through again, the Immortal Dao reached the eightfold of the Imperial Realm, and the Martial Dao took the lead in reaching the ninth level of the Dragon and Tiger Realm.

This made him full of confidence, and as long as he practiced penance for another month, he believed that the Immortal Dao would also be able to reach the Ninth Fold.

Just when he was full of confidence, a new problem arose, and the aura of this place began to thin out.

Lu Yun was stunned, could it be that the aura in this place was sucked dry by him?

At the same time, he also wondered, where does the aura come from, and why is it stronger than the aura of Chang'an?

He had discussed this issue with Zhuo Buyan, but unfortunately Zhuo Buyan didn't know it, because not everyone could feel the aura, so there was no relevant record.

There are too many theories about the source of the aura, some say that the aura comes from under the earth, but after breaking through the earth for tens of meters, the answer has not been found.

Some people also say that Reiki is the natural birth of heaven and earth, but it cannot be verified.

Of course, some people say that aura is a special thing produced by the spirit of mountains and rivers, so the famous mountains and rivers are full of aura, but this statement is also unreliable, and there are some places where the aura is strong.

Lu Yun carefully felt the aura around the small lake and found that the place where the aura was strongest was located in the small lake.

Lu Yun jumped directly into the small lake, slowly dived to the bottom of the lake, and followed the feeling to find it.

The small lake is not deep, only a few meters, and there are some other fish and aquatic plants in the water.

Like a fish, he slowly searched the bottom of the lake, and finally found the place where the aura was most intense.

There is a deep cave that connects with the underground river, so a small lake is formed here.

Next to the deep cave, there was a small piece of crystal liquid, exuding a rich aura, which made Lu Yun happy.

He approached the liquid, reached for a small lump, and immediately knew what it was.

Lu Yun once asked Zhuo Buyan about the spirit stone, and in addition to explaining the spirit stone, Zhuo Buyan also explained another thing, called spiritual liquid.

This mass of liquid is the spiritual fluid, which is something formed by the spiritual energy that is rich enough to a certain extent.

The aura can be volatilized into aura, and the aura between heaven and earth is basically emitted from the aura.

Of course, if the amount of spiritual liquid is extremely large, it accumulates to a certain extent, and then undergoes the baptism of time, it can be turned into a spirit stone, so the spirit stone is even more precious.

These spiritual fluids obviously came from underground, gushing out through this deep hole, and it is precisely because of these spiritual fluids that the spiritual energy here is richer than other places.

Several other places where the aura is rich should also have such spiritual liquid.

By observing the traces of the spiritual liquid, Lu Yun knew that there was originally a large mass of spiritual liquid here, but it was all emitted into spiritual energy, leaving only this little bit behind.

Just such a little bit is much more precious than aura, Lu Yun carefully put away all the spiritual liquid.

He didn't take these spiritual liquids, because spiritual liquids, like spiritual stones, have a more important role, and it would be a waste to use them directly for cultivation, and besides, Qinling was not short of spiritual energy.

The source of the aura is a mystery, and Lu Yun is destined to find no answer now.

He originally hoped to reach the realm of Double Ninefold with the rich aura here, but now he could only smile bitterly.

The top priority is to find another place with a strong spiritual aura, seize the time to cultivate, and let the immortal path reach the ninth level of the imperial realm.

Fortunately, there was no shortage of places with strong spiritual energy here, and Lu Yun soon found another mountain peak, which was occupied by a demon tiger.

Lu Yun came to this mountain peak, and as soon as he pulled out the Xuanyuan Sword, the tiger ran away, and there was an anthropomorphic expression of fear in his eyes, which made Lu Yun stunned for a while.

These demon beasts really have spiritual intelligence, which is not comparable to ordinary beasts.

Lu Yun practiced cross-legged here, and in the blink of an eye, a month passed, and the aura here thinned down again, but his immortal path had finally reached the ninth level of the imperial realm.

In addition to the Immortal Dao, his martial arts have also gone further, his true qi has become more vigorous, and his body has been strengthened again.

Lu Yun searched carefully here, trying to find the spiritual liquid, but found that the spiritual liquid should be located in the mountain, which made him have to give up.

Seeing that there was still time, Lu Yun changed places again and continued to cultivate, wanting to reach his peak realm.

In another place where the aura was strong, after Lu Yun had cultivated for three days, his eyes showed surprise.

He found that his spirit could still grow, but his true qi could no longer increase at all, and it seemed that it had reached the extreme, and it could no longer be increased.

Of course, the physical reinforcement has also completely stagnated, and the strength has not been enhanced.

Lu Yun pondered, could this be that he had reached the extreme, and he was now at the peak of the Dragon and Tiger Realm.

He thought of what Li Qingfeng had said about the peak of the Dragon and Tiger Realm and the Mountain and River Realm, and finally understood why the strength of the Mountain and River Realm was the same as the peak of the Dragon and Tiger Realm, because it was impossible to increase it.

Of course, it's not that it can't be enhanced, but it's impossible to strengthen it with this method, and I'm afraid that a special cultivation method will be needed next.

It's a pity that he doesn't know how to practice and how to step into the realm of mountains and rivers.

Because the path of inheritance was broken, he lacked the ways and means to continue his practice.

Lu Yun shook his head, this was not something he could solve.

But fortunately, his spirit can still be enhanced, and he can continue to cultivate the Immortal Dao, so that his spirit can also reach the peak of the Imperial Realm.
