Chapter 61: Open the base!

　　 Lu Qing felt that he had been out of the body for a long time this time, and was about to reach his limit.
　　 Originally, it would take a whole day and night to go back and forth to this water ghost lake. Lu Qing calculated the time and arrived on the eve of the battle. After watching the battle, he waited until Lu Chaoxi took the yin marrow water jade. It was time to go back, but found that this underground Lingxi couldn't hold back, and went down to explore...
　　 If you don't rely on karma to replenish it, you can't go back.
　　 But fortunately, today’s battle did not use the expensive exchange item [Enlightenment Force]. Lu Qing still had more than 300 karma in his hand, which was enough to spend.
　　 So, after thinking for a while, he flew to the upper reaches of Lingxi.
　　 He wants to find, where is the source of Lingxi.
　　 The magic is that the more you fly, the lower you go.
　　 This Lingxi is actually flowing from low to high!
　　 Lu Qing was a little surprised, but that was it. There are many places in this world that cannot be estimated by the common sense of the earth in the previous life. Under spiritual power, spiritual energy, and immortality, all magical things can happen.
　　He kept flying along the Lingxi River. For a whole day, after the karma replenishment, he couldn't find where the source was. The more downward, the aura becomes more and more dense. After flying for a day, the water aura escaping from the Lingxi almost all reached the level of the fourth-order spiritual vein. When Lu Qing was alive, the Yuyan Mountain he cultivated himself was only a fourth-order spiritual vein.
　　 But despite this, this is still not the source, and there is no new sign happening at all. The aura's intensity has been slowly increasing, and I don't know how far this deep underground Lingxi has flowed.
　　 After thinking for a moment, Lu Qing had to stop.
　　 He has to go back.
　　As a Golden Core monk before his death, he certainly didn't worry that he would get lost and find his way back. But after all, he is only a spiritual body now, and he cannot leave Yuyan Mountain for too long. If he is too far away, he will spend too much spiritual power for no reason.
　　 He can only regret leaving.
　　 He estimated the time and distance. It has been almost two days since he came out of the mountain. It is estimated that it will take at least two days to go back. It adds up to four days outside, and the karma at 14 o’clock is so gone...
　　 But not too bad.
　　 Not to mention the secrets in the depths of Lingxi, just the current discovery is already a great fortune.
　　 There must be some secrets hidden in the depths of Lingxi. Judging from Lu Qing's eyes, it is very likely to be an undeveloped and unknowing cave.
　　 If you can go on exploring, it will definitely be able to obtain huge benefits, even far more than a piece of yin marrow water jade. Moreover, Lu Qing believes that this piece of yin marrow water jade might have been gradually leached out by Lingxi over thousands of years.
　　He is very interested in this, if he is still alive, he will definitely continue to explore.
　　 But obviously, the current Lu family obviously didn't have the capital to explore this secret land. Even if they explored it, they couldn't hold back such a large interest.
　　 Not to mention the deeper part of Lingxi, even this underground Lingxi itself has a fourth-order spiritual vein in the middle.
　　 Even if it's only the fourth-order spiritual vein, the current Lu Family is afraid that it can't hold it.
　　 It's better to let it be buried deep underground. In the future, the Lu family will become more prosperous and qualified to develop this secret, so you can think about it further.
　　 However, even at the moment, there are ways to use this underground Lingxi.
　　 Lu Qing had already figured it out on the way back to Yuyan Mountain.
　　 He has already ascertained the location of Lingxi in the ground. In the future, he can drill a well on the shore of the lake to connect to the underground river, and think of ways to draw water from it.
　　According to his estimation, when the time comes, next to the Lingjing, he will use the water he pumped up to practice. Even if the loss of water after leaving the Lingxi is included, it is at least equivalent to the effect of the second-order spiritual vein training.
　　Furthermore, the follow-up family has a deeper control over this Lingxi River. From its branch to the ground and infiltrating the lakeshore area, the time will be longer, and the family can have a real spiritual vein at a small price.
　　 Lingmai is an extremely important resource for monks.
　　 Cultivation of a monk requires spiritual energy. And the conventional way to obtain spiritual energy is either to refine it between heaven and earth, or to refine it from spiritual stones.
　　 For a Qi training monk, at least one spiritual stone is required for one month of training. If you reach the seventh level or above, you will have two. This consumption standard is necessary to ensure that the progress of one's own cultivation is normal. If it is less than this number, let alone improvement, it is possible for the cultivation to regress.
　　 Without using spiritual stones to practice, you can only refine the spiritual energy of heaven and earth.
　　 Heaven and earth aura is right everywhere, but not every place is strong. In ordinary places, the refining speed is too slow to satisfy the cultivator.
　　 Only spiritual veins can support cultivation.
　　 The so-called spiritual channel is the place where the natural spiritual energy converges.
　　 First-order spiritual veins are the most common, maybe there is one in a barren mountain. Many small families and casual cultivators have no choice but to find a place to be built as a cave and cultivate in it.
This kind of lowest level spiritual veins can only support the cultivation of monks in the Qi refining period. If you want to build a foundation for monks, you still need to use spiritual stones to fill in, at least ten in a month. More than a hundred spirit stones, the time stretched a little longer, and couldn't hold it at all.
　　 So, the foundation-building monk had to find the second-order spiritual vein.
　　 The general second-order spiritual veins can actually only support the cultivation of a few foundation-building cultivators. The specific ones depend on the quality of the spiritual veins themselves.
　　 If it exceeds, the foundation-building cultivators will compete with each other for spiritual energy, and they will not cultivate well. After reaching the upper limit of the spiritual veins ~EbookFREE.me~, at best, bring some other Qi training monks, and you can practice with some exhaust gas.
　　 When it's the Enlightenment Period, then the third-order Spirit Vessel is needed.
　　 But it’s easy to destroy the spiritual veins, find the veins, and it’s over if it blows up.
Yuyan Mountain used to be a Tier 4 spirit vein. In the battle that Zhao family came to the door, the core of the spirit vein was continuously bombarded by spells during the battle, causing considerable damage. It was reduced to Tier 2, but at Tier 2 The middle class is still top grade, so it can barely support the four foundation-building monks.
　　 But nurturing is too difficult.
　　 Yuyan Mountain wants to take a step up and reach the third level, at least to invest more than 50,000 spiritual stones as the cost of cultivation.
　　 The cost of this spirit stone is forgotten, the key is to slowly raise it for at least a hundred years before it can be raised.
　　 is expensive and time-consuming.
　　 But often high-level monks must need spiritual veins, otherwise, in the Enlightenment period, the cost of spiritual stones for one year of cultivation will cost one to two thousand. It’s not a long time to practice on the Great Dao Road, and it’s not unusual for a Qiming monk to retreat for ten years and not come out for twenty years. If there is no spiritual vein, one or two thousand spiritual stones will be spent in a long retreat practice to break through the realm. With the worth of Qiming monk, he couldn't stand up to such a cost.
　　 Lingmai is almost a must for monks, let alone family and sect.
　　 Now, the Lu family is actually about to face this problem.
It was fine before Xue Ting built the foundation, but now, the family has four foundation-building monks and fifty Qi training monks, which have exceeded the limit of Yuyan Mountain's spiritual veins. The cultivation of family monks will definitely be affected. .
　　 Before, Lu Qing was still having a headache, but now, he found that the underground Lingxi came at the right time and relieved his urgent need.
　　 "Ready to open a base!"
