Lu Qing felt that he had been away from the body for a long time this time and was almost at his limit.

Originally, it would take a day and night to go back and forth in this Water Ghost Lake. Lu Qing calculated the time and came on the eve of the battle. After watching the battle, Lu Chaoxi took Yinmaru Water Jade. He should have gone back, but found that the underground Lingxi couldn't help but go down to investigate...

If you don’t rely on karma to supplement it, you will definitely not be able to go back.

Fortunately, today's battle did not use the expensive exchange item [Power of Qiming], and after fighting the Water Ghost, it was enough to spend more than 400 karma.

So he thought about it and flew towards the upstream of Lingxi.

He wanted to find out where the source of Lingxi was.

What's amazing is that the more you fly, the more you go, the more you go.

This Lingxi actually flows from low to high!

Lu Qing was a little surprised, but that was it. In many places in this world, many places cannot be guessed by common sense from the earth in the past. Under spiritual power, spiritual energy, and immortal magic, any magical thing may happen.

He kept flying along the Lingxi River. After a whole day, after replenishing his karma once, he failed to find out where the source was. The further downwards, the spiritual energy became more and more intense. After flying for a day, the water spiritual energy emitted from the Lingxi River almost reached the level of the fourth-level spiritual vein. When Lu Qing was alive, the Yuyan Mountain he personally cultivated was only the fourth-level spiritual vein.

But despite this, this place is still not the source, and there is no new sign at all. The intensity of spiritual energy has been slowly increasing. I don’t know how far this spiritual stream buried deep in the ground has flowed.

After thinking for a while, Lu Qing had to stop.

He still has to go back.

As a Jindan monk during his lifetime, of course he was not worried that he would be lost and could not find the way back. But after all, he is just a spiritual body now and cannot leave Yuyan Mountain for too long. If he is too far away, he will spend too much spiritual power for no reason when he goes back.

He could only say goodbye regretfully.

He estimated the time and distance. It had been almost two days since he came out of the mountain. He had to go back for at least two days. In total, he was floating outside for four days, and the karma was gone at 14 o'clock...

But it's not too much of a loss.

Not to mention the secret deep in Lingxi, just the current discovery is already a great fortune.

There must be some secrets hidden deep in this Lingxi River. From Lu Qing's perspective, it is likely to be a blessed land of untapped and unknown to anyone.

If we can continue to explore, we will inevitably gain huge benefits, even far larger than a piece of Yin Marrow Water Jade. Lu Qing even believes that this piece of Yin Marrow Water Jade may have been gradually soaked in Lingxi over thousands of years.

He was very interested in this. If he was still alive, he would definitely continue to explore.

But it is obvious that the Lu family now has no capital to explore this secret land. Even if they explore it, they cannot defend such great benefits.

Not to mention the depth of Lingxi, even this underground Lingxi itself has a fourth-level spiritual vein at the middle.

Even if it is just a fourth-level spiritual vein, the Lu family is afraid that it cannot be defended now.

It would be better to let it be buried deep underground. In the future, the Lu family will be more prosperous and are qualified to develop this secret. If you think about it further, you will think about it.

However, even now, there are ways to use this underground Lingxi.

Lu Qing had already thought it through on the way back to Yuyan Mountain.

He has already discovered the location of Lingxi underground. In the future, he can dig a well down the shore of the lake to connect the underground river and find some ways to pump water from it.

According to his estimate, at that time, by using the water pumped up next to the spiritual well, even if the loss after the water leaves the Lingxi River is included, it will be at least equivalent to the effect of practicing in the second-level spiritual veins.

Moreover, the family will have a deeper control over this Lingxi in the future. From the opening of a branch to the ground and soaking the lakeshore, the family will have a real spiritual vein at a very small price.

Spiritual veins are extremely important resources for monks.

Cultivators need spiritual energy when practicing. The conventional way to obtain spiritual energy is either to refine it between heaven and earth, or to extract it from spirit stones.

For qi-training cultivators, they need at least one spirit stone for one month to practice. When they reach the seventh level of Qi-training, they need two. This consumption standard is necessary to ensure that their own cultivation progress is normal. It is less than this number. Not to mention progress, it is possible to regress in cultivation.

Without spiritual stone cultivation, you can only extract the spiritual energy of heaven and earth.

It is true that there is spiritual energy everywhere in heaven and earth, but not every place is very rich. In ordinary places, the refining speed is too slow and cannot satisfy the practice of monks.

Only spiritual veins can support cultivation.

The so-called spiritual veins are the place where natural spiritual energy gathers.

The first-level spiritual vein is the most common. Maybe somewhere is a barren mountain. Many small families and casual cultivators have no choice but to find a place to open it into a cave and practice it in it.

This lowest level spiritual vein can only support the cultivation of cultivators in the Qi Refining Stage at most. If a foundation-building cultivator wants to maintain cultivation, he still needs to fill it with spirit stones. There are at least ten in a month, and in a year, he will need more than one hundred spirit stones alone. The time will take longer and he can't hold on.

Therefore, the foundation-building monks have to find the second-level spiritual vein.

But the average second-level spiritual vein can only support the cultivation of a few foundation-building monks. The specific number depends on the quality of the spiritual vein itself.

If it exceeds the price, the foundation-building monks will compete for each other's spiritual energy, and they will not practice well. After reaching the upper limit that the spiritual vein can bear, at best, bring some other Qi training monks, and you can practice it even if you smell some exhaust gas.

When the Qiming period arrives, you will need the third-level spiritual vein.

But it is easy to destroy the spiritual veins. Find the heart of the veins and explode.

Yuyan Mountain was once a fourth-level spiritual vein. In the battle when Zhao came to the door, the core of the spiritual vein was continuously bombarded by magic during the battle, and the damage was quite large. It was reduced to the second level, but it was still a top-level in the second level, so it could barely support four foundation-building cultivators.

But cultivating is too difficult.

If Yuyanshan wants to take a step up and reach the third level, he will have to invest at least 50,000 spirit stones as the cost of cultivation.

It’s fine to spend this spirit stone, but it will take at least one hundred years to raise it slowly before it can be raised.

It's both expensive and time-consuming.

But often high-level cultivators must need spiritual veins, otherwise in the Qiming period, the spiritual stones required for one or two thousand per year will be spent. A great way of practice is not a unit that is too long. It is not ordinary for a monk Qiming to stay in seclusion for ten years and not come out for twenty years. If there is no spiritual vein, he will go through the realm of retreat in one go and practice for a long time, and he will have to go out for one or two thousand spiritual stones. With the value of a monk Qiming, he cannot withstand such expenses.

For cultivators, spiritual veins are almost a must-have, let alone families and sects.

Now, the Lu family is actually going to face this problem.

It was okay before Xueting built the foundation, but now, the family has four foundation-building monks and fifty Qi training monks, which has exceeded the limit of the Yuyan Mountain Spiritual Vein. The cultivation of the family monks will definitely be affected to a certain extent.

Before, Lu Qing was still having a headache about this matter, but now he found that the underground Lingxi River was coming just right, which solved the urgent problem.
