After thinking for a while, Liu Han took a deep breath, dived slowly, dived down, every time he dived a distance, he stopped, felt it, it was estimated that he had dived for more than a zhang, and began to feel the aura, but the aura was thin, and he continued to dive, and the aura slowly thickened.

Liu Han didn't expect it to be so deep here, the further down, the stronger the aura, if it is said that on the surface of the water, there is no aura at all, when it reaches more than one zhang, you can feel the aura, and then when it goes down to about two zhang, the concentration of aura has reached the level of the cave in the mysterious courtyard of the imperial capital, and it dives down I don't know how deep, Liu Han's feet fell into the mud and sand.

He looked around, and there were dense aquatic plants all around, these aquatic plants were not tall, only about a foot high, and the short ones were only about half a foot, but there were no animals in the grass.

After seeing his surroundings clearly, he began to move slowly along the mountain wall, the silt at the bottom of the water was very thick, and as he moved, the silt stirred, and the water became slightly muddy, he immediately noticed it and became more careful.

A clump of aquatic plants appeared in front of him, he moved cautiously, and when he reached the edge of the aquatic weeds, he felt that the aura here was more abundant than other places, and he walked around the aquatic weeds, which were relatively large, and it took a lot of time to walk this circle, and he felt a little difficult with the strength of his inner breath.

Closed breath, turned to the inner breath, this is still a kung fu that Yao Lao taught him in private, he relied on this kung fu to hide in the deep pool, escaped the pursuit of the tiger guard, before knowing Shennong Valley, he didn't know much, but now, he felt that this was a hidden immortal sect exercises, Yao Lao probably also wanted to recruit him to Shennong Valley.

After a short rest, he surfaced, leaned against the stone wall, and let the Five Elements True Yuan run for three weeks before diving under the water again, he suddenly remembered what Qing Ling had been, in places where the spiritual energy was luxuriant, most of them were accompanied by spirit grass or spirit objects, and the longer the spirit grass was often accompanied by fierce spirit beasts.

I didn't see any spirit beasts here, but the aura was very dense, maybe there were spirit grasses, and those water plants were not spirit grasses?

Thinking of this, after Liu Han dived to the bottom of the water, he first observed the spirit grass, and recalled in his mind the "Record of Strange Things in the World" that he had seen in the Qingxu Sect, this "Record of Strange Things in the World" recorded all the animals and plants in the world, and these animals and plants were all extremely rare spirit grass spirit animals.

This book of strange things was asked by Qingling to show him, he is the world of the Qingxu Sect, to find all kinds of spirit grass and spirit beasts for the Qingxu Sect, the spirit grass can be dispensed, and the inner pill of the spirit beast can also be dispensed, due to the lack of aura, the current immortal cultivators are very dependent on medicine, and drugs are needed to break through the realm, and drugs are also needed to improve cultivation, so any spirit grass spirit animal will cause the competition of immortal cultivators.

Liu Han carefully observed the aquatic plants, the light at the bottom of the water was insufficient, it was difficult to see the appearance of the water grass, he wanted to pick a bush, but after thinking about it, he continued to walk around the aquatic plants, and it was easy to find a bright spot, and he could see the appearance of the water plants.

This aquatic plant is a bit similar to the orchid that his mother had planted in his previous life, the leaves are a little flat and slender, but strangely, this leaf has a convex section every half finger, like a bamboo knot.

Seeing this feature, his eyes lit up, and his mind suddenly flashed to the record in the Strange Things Record:

Stick grass, aquatic grass, grows one section every 100 years and matures in 300 years.

He stroked the stick grass and felt that there were seven or eight bamboo joints, which did not mean that it was seven or eight hundred years old, which made him extremely excited.

Coming out of the Qingxu Sect, Qingling gave him a catalog, which contained all kinds of spirit grass spirit beasts needed by the mountain gate, including this stick grass, which was marked as the best for more than three hundred years, but he searched all the pharmacies in the imperial capital, but he didn't find this stick grass, but he didn't expect to meet it here.

After being excited, he was a little embarrassed, if this stick grass was to be dug down, it must be sent to the Void Sect immediately, otherwise the spiritual energy would be lost, and the medicinal value would drop immediately, and it would not be in vain.

After thinking about it for a while, Liu Han didn't touch these stick grasses, and at a glance, although there are a lot of stick grasses here, I am afraid that these few bushes are precious, and there is less aura on the periphery, and I am afraid that the preciousness is much less.

Swimming between these bushes of bamboo grass, Liu Han was still looking around, his spirit was highly vigilant, for fear that a monster that he had never seen before would emerge from the bottom of this black rumbling water, but the fact was that the surroundings were quiet, and he felt the thickness of the aura while swimming, and whenever he found that the aura began to thin, he changed directions.

After changing directions, he came to a bamboo grass, where the bamboo grass was very high, the highest had more than a dozen knots, according to the records in the book, these bamboo grasses should be thousands of years old.

Although he was highly educated in his previous life, but in this era, he has seen everything impossible, and these thousands of years of stick grass can no longer surprise him, this stick grass has a large range, with a radius of more than ten zhang.

Liu Han looked at the swarthy grass, and confirmed that this was the place with the most abundant aura, and there would be no other place, he looked around, and the surroundings were still quiet, and he suddenly felt that there was a bit of a strange place here, there were no fish or other animals.

Even if there is a treacherous whirlpool outside, it should not be without fish, and it is too peaceful here.

After thinking about it for a while, Liu Han picked up a stone and threw it into the grass hard, but there was no movement in the grass, he still didn't give up, and threw it in seven or eight pieces in a row, but the grass still didn't move.

Now he was relieved, slowly swam to the edge of the grass, tentatively reached in, no accident happened, just about to go in, he suddenly changed his mind, around the grass, until the edge of the grass stone wall, he stuck to the stone wall, slowly swam, try not to make any movement.

He grabbed the stone wall and swam forward, and then moved laterally, and soon reached the upper end of the grass, leaned down and looked down, the grass was dark, and he could not see any movement, he was slightly condensed, and his inner breath moved into his eyes, and his eyes soared, but he still did not see anything.

After thinking about it, he still didn't go down, but half climbed up and half floated, and soon his head emerged on the surface of the water, and the water flow near the mountain wall was very calm, looking like a puddle of still water, and there was no connection with the Yangtze River rushing outside.

Look at the sky, the sky is already cloudy and bright, and after a pillar of incense, the sky should be bright, at this time, he suddenly felt that there seemed to be something underwater, and there was a sudden movement underwater.

Taking a deep breath, he pulled out the long knife, thought about it, put the long knife into the sheath again, pulled out the short dagger, habitually took a deep breath, and slowly slid down the wall.

Towards the bottom, he saw that the whole grass was like a school of frightened fish, and he kept shaking, and when he looked closely, the stick grass was dancing in one direction, but it seemed to resist that direction.

Liu Han stared in that direction, he couldn't see anything, but he could clearly feel the water surging in that direction, he slowly moved a few steps to that side, and then felt a huge suction force dragging him towards that direction.

He was taken aback, and quickly managed to stabilize his body, and when he looked again, the water was rapidly surging inside, forming a huge whirlpool in the middle of the aquatic plants.

No wonder it's so quiet here, it turns out that there is still this strange phenomenon here.

Liu Han took a deep breath, sank his arms, and slowly moved downward, the direction of this suction was to the left of the direction he went up.

Slowly moving up the stone wall, he finally found a hole, this hole was dark, hidden deep in the grass, the light under the water was already very dark, and the hole hidden in the grass was even darker, if it were not for this water, he would not have been able to see this hole at all.

Liu Han had been hanging on the stone wall, his inner breath flowing slowly, resisting the growing attraction, and after about two pillars of incense, the water flow suddenly calmed down, as if nothing had happened.

He stared at the hole, there must be something strange in there, there must be something in it, what was it doing?

"Even if there is a monster with three heads, so what, even the immortals have seen it, what else!" He suddenly smiled, and laughed at himself in his heart, the world has given him too many surprises, even if there are more surprises, what is the big deal.

Thinking that he slowly moved to the top of the cave, and then slowly descended, this distance was very short, but it took half a column of incense.

Standing next to the entrance of the cave, he looked into the cave, it was dark and swarthy, and he couldn't see anything clearly, but he felt that the aura in the cave was very abundant, much more abundant than the small courtyard in the imperial capital, and it was only a little bit compared to the Qingxu Sect.

He didn't go in directly, his consciousness let go, and at first, it was empty, there was nothing, and he was not only a little puzzled, how did this strong suction come from?

After thinking for a while, he planned to go in to see what was strange in it, but suddenly, the water flow became fierce again, and it rushed into it frantically, he couldn't help but be shocked, and hurriedly grabbed the stone wall to stabilize his body.

Suddenly, a glimmer of light came out, and he couldn't help but be surprised, there was actually a bright light here, and his divine sense hurriedly released it.

The divine consciousness flowed into the water, and there was still nothing in it, but he made a new discovery, the water flow was divided into two streams, the upper half went in, and the lower half was actually out, and he suddenly understood what was going on with the whirlpool here, that is, this water flow in and out, intertwined at the bottom of the water, so that the water surface formed a huge whirlpool.

The cave is not deep, and what makes Liu Han wonder is that there is actually a spring in the cave, and it is still bubbling outward.

And near the spring, the aura is the most abundant.

What is this? Liu Han thought about it, and suddenly remembered a booklet he saw in the Qingxu Sect, this booklet was about the Lingshan Spiritual Land, written by an unknown predecessor of the Qingxu Sect, maybe he was nostalgic for the previous era when the spiritual energy was abundant, maybe he wanted to leave some records for the younger generations, he described various forms of spiritual energy in the booklet.

Here is an introduction to a kind of aura called Lingquan, which is, as the name suggests, that the aura spouts out from the ground like a spring.

There's actually a spiritual spring hidden here!

Liu Han couldn't help but be surprised, and in addition to being excited, as soon as he let go of his hand and was about to enter, a huge suction force came, and he hurriedly grabbed the stone wall again and stabilized his figure.

The light was brighter, the stick grass danced more intensely, and the whirlpool outside was more violent.
