Looking at the jagged stalactites above his head, Lin Tian remembered the use of stalactites.

There is a precious medicinal material in the Shiquan Dabu Decoction that the doctor got for Qian Qiaohe, which is stalactites.

Here in the Underground Nether City, the name of the stalactites is Huangshi Sand.

Lin Tian remembered clearly that when he was at the rest stop, he saw Ling Feicheng posting on the trading platform to buy Huangshisha medicinal materials.

Lin Tian clearly remembers the medicinal functions of stalactites.

It is sweet and warm in nature, enters the lung and kidney meridian, has the effect of warming lung qi, strengthening yang, and releasing milk. It is often used to treat fatigue and asthma and cough, cold cough, impotence, cold numbness of waist and feet, and lactation obstruction.

However, the really useful part should be transparent and thin, something like a tube works best.

Lin Tian raised his head and began to pay attention to the stalactites above his head. He looked for a better one and collected it.

Just doing it casually, there is a lot of space to store the ring.

He suddenly felt mischievous.

"When you get to the rest stop, trade the yellow stone sand to Ling Feicheng and blackmail him for a sum of money."

Just thinking about that scene makes Lin Tian feel happy.

Who told him to think of himself as being taken advantage of? It was time for him to let Ling Feicheng experience the feeling of being a fish in water.

After Lin Tian searched for it, he tapped it with the hilt of his sword and found a pile of yellow sand, no less than a hundred of them.

"It's almost time to do other things."

Lin Tian took a look at the surrounding environment and found that he had gone deep into the cave without knowing it.

However, we haven't seen large areas of water yet.

It is probably too dry, and there is only a little water underground at such a deep place.

According to the characteristics of Shuixing Tree, it is impossible for it to find this place without a large area of ​​water source.

Lin Tian continued to walk down patiently. When he reached almost 500 meters, he heard the sound of running water.

"It's not a rushing river, it's an underground pool."

Lin Tian felt that he was about to see hope and quickened his pace. After a while, a new world appeared in front of him.

As he thought, this mountainous world without any vegetation was not completely dead. Its real vitality lay underground.

Lin Tian felt that he was about to see hope and quickened his pace. After a while, a new world appeared in front of him.

As he thought, this mountainous world without any vegetation was not completely dead. Its real vitality lay underground.

A clear underground river blocked the way ahead. How big it was, Lin Tian could not see clearly, as it was blocked by some lime and stalactites in the river.

It can be seen that this underground river is very rich in water resources.

Lin Tian looked at the sparkling river surface under the light and the crystal clear water quality, which made him interested.

When he thought of something, he shook his head again.

"The water in this kind of cave is hard water and cannot be drunk. It may be fine for taking a shower.

Why not see if there are any fish in the river?"

He looked at the bottom of the river and looked inside carefully, and was pleasantly surprised.

There are things swimming in the river, but their bodies are transparent.

"These creatures living in caves are accustomed to such a light-free environment. They do not need eyes, their skin is very thin, their respiratory organs are degraded, and their metabolism is relatively slow.

In a sense, ‘you will die when you leave the cave’.

Check to see if there are any fish, I wonder what the cave fish that live in the cave taste like."

Lin Tian planned to catch a few fish to have a try.

He took out two nets from the storage ring and fished them out.

After weaving the fishing nets last time, he left two nets for himself, and they were put to use now.

He fished with a net in each hand and opened his eyes to see more accurately.

"What a fish! It has a long body, a pointed head, and its scales are almost gone."

It looks delicious.

Lin Tian locked his eyes on the fish, lay down on the shore, and quickly caught it in a net.

That fish probably rarely encountered a predator like Lin Tian. It moved very slowly and fell into Lin Tian's net before it could react.

"One!"

Lin Tian took out a relatively deep basin, scooped some water, and threw the fish into the basin.

"Keep going, we have fresh fish to eat today."

"Two!"

When Lin Tian caught the third fish, there was a fist-sized stone under the fish that caught his attention.

There was something wrong with that stone. When he took a closer look, he felt that it was emitting an aura of spiritual energy.

"Pick it up and see what it is."

Lin Tian picked it up and when he touched the stone, he was shocked.

It is rich in spiritual energy, a lot of spiritual energy!

Lin Tian remembered the treasure atlas he had collected, which contained such spiritual stones.

"It's a natural spiritual stone!

Natural spiritual stones have the purest and most abundant spiritual energy underwater, which is much better than the spiritual stones on the market.

The spiritual stones on the market are spiritual stones mined from the surface. They have been polished to uniform specifications, and are far inferior to the quality of natural spiritual stones from the bottom of the water.

Natural spiritual stones are used for cultivation, and the speed is faster than ordinary spiritual stones."

Lin Tian held the smooth natural spiritual stone and raised the corners of his mouth.

"No wonder the fish in this river grow so well. Maybe they are nourished by the spiritual energy escaping from these spiritual stones."

This is a good harvest. Lin Tian has picked up another treasure.

He narrowed his eyes and looked towards the vast river.

"There should be more than one spiritual stone at the bottom of this water."

In the world of cultivators, especially in this world, spiritual stones represent assets.

You must know that when Lintian sells bright stones, one can sell up to three large spiritual stones, but this natural spiritual stone can be picked up for free.

If there are more, then the forests and fields will be developed, and there will be no need to worry about not having spiritual stones.

"Look again!"

Lin Tian, ​​who was originally keen on finding fish, entered another channel. He wanted to find natural spiritual stones!

Not long after, he found three or four more natural spiritual stones.

"The combined value of these natural spiritual stones is even more valuable than the eleven large spiritual stones we got from selling the light stones last time."

Lin Tian's heart is burning. I'm afraid there is a natural vein of spiritual stone at the bottom of the river, right?

"I'm going to change my strategy. I originally wanted to camp here, find food and fresh water, and spend these seven days safely."

But now, collecting natural spiritual stones has become another important goal for him.

"If you want Karina to regain her strength quickly, you need to provide a steady stream of spiritual stones.
