Chen Xuan learned that his brother had offended Xuantian Sect, and before he was sure that the danger was completely over, he would say that he would stay in the grass house.

Xingyu may be killed at any time, and the fat man can't wait for more helpers, so he won't refuse.

Wang Hao took Old Man Su away from the small building, the purpose was very clear, he didn't want to go back to Chengdu in the future, and he didn't want to see the people of Shushan again. After going down the mountain, he wandered around, and at first he didn't think there was anything, but sending people under the fence was not a long-term solution, especially after receiving Xingyu, he found that a small nest was indispensable.

The grass house is the place where the fat man grows up, and when he wants to decorate the nest, he chooses the grass house almost without thinking.

If you have a small nest, you have to be popular, Wang Hao doesn't have many friends, although he refuses to admit that he has a master-apprentice relationship with Old Man Su, but the fact is a fact after all, he built a foundation for Old Man Su with his own hands, and he is at least half an apprentice, so he brought Old Man Su to the grass house.

Old man Su is an understanding person, there is no better master than the fat man in the world, at least he can't find it, he can move to the grass house to practice, that is what he dreamed of, from now on, the grass house is his master, thinking of this, he smiled, this old man didn't take his granddaughter's situation seriously.

Cultivators do not have high requirements for materials, and a comfortable environment is best inaccessible, and the lack of spiritual energy can be made up for with formations, and nothing else.

Wang Hao's original plan was to use the old method to use the formation to release the energy of the spar, but the scale was not much larger than before, and the formation should cover the peak where the grass house was located.

Chen Xuan objected on the spot, because the consumption of spars was too large, and he made a rough estimate to maintain the operation of the formation. At least hundreds of spars must be ignited at the same time, and the spars must be replaced every three months, and the more people cultivating in the formation, the faster the energy will be consumed. The faster the wear and tear of the spar, this kind of play, even if the big money also goes bankrupt, is not a long-term solution.

In the long run, Wang Hao wants to create a blessed land, and the aura does not need to be too dense, it is equivalent to an ordinary spiritual vein, in fact, when the aura is dense to a certain extent, the effect is almost the same. What the fat man did before was a complete waste.

"Oh, is there a better way to do that? It can reduce the consumption of spars. Wang Hao took out a spar and threw it around in his hand, if there was no suitable method. The previous method can also be considered, anyway, there are endless squandering hedrons on Gongga Mountain.

Chen Xuan smiled bitterly. "Brother, if I had a better way, I would have told you a long time ago. Although it is simple and easy to release the energy of the hedron with the formation, the cost is too high. Unless the heart rushes into the infancy, it is not suitable for long-term or large-scale use. With my knowledge of formation, I really can't think of a way to do it once and for all. However, the brother is a generation of alchemy masters, or he may be able to find another way. ”

"You said to use alchemy to solve it? Alchemy is to adopt the spiritual energy of heaven and earth treasures, but now it is to release the energy of the spar, which is completely contrary, can it be done? Wang Hao scratched his head vigorously.

"Okay, I'm going to ask you, you're an alchemy master, I'm not, anyway. The formation can't solve this problem, if even you can't do anything, then you can't find anyone who can do it. Chen Xuan's words are not arrogant, the two of them are the pinnacle of Dan Dao and the formation respectively, this is self-confidence, a kind of momentum that gives up on others, there has never been a time when others rely on Chen Xuan, and there is no time when Chen Xuan relies on others.

Since ancient times, cultivators have been spiritual veins that hurt their brains, and the Xuanmen sect has been blessed for a cave. Even at the expense of a big fight. Although Chen Xuan used a compromise method, it was just a temporary solution. Artificially creating a spiritual vein, and it can exist for a long time, this is a new attempt, a peak challenge, even Chen Xuan is a little excited.

Wang Hao fell into contemplation in an instant, the remaining three people were inconvenient to disturb, and waited silently on the side, Xingyu also discussed the solution with Chen Xuan, although the formation could not directly make the spiritual vein, but it could play an auxiliary role, both of them were experts in the formation, and they overcame difficulties together, and immediately indulged in it after cutting into the topic.

Old man Su was in a fog when he heard it on the side, so he simply found a remote place to cultivate.

As the saying goes, if you don't break out in silence, you break out in silence, and in the early morning of the next day, Wang Hao broke out after all. With his roar, Chen Xuan and the others were immediately shocked and surrounded him.

"Tell me about it." Three pairs of expectant eyes stared at the fat man.

Wang Hao coughed dryly at first, and then explained slowly: "This, we all know that aura flows around like water, but it is different from water, water flows from high to low, but aura is just the opposite, it flows from thin places to dense places. ”

Chen Xuan interjected: "That's true, the spiritual energy always flows to dense places, the more blessed the heavens and the blessed land, the more it can absorb the spiritual energy of the surrounding land to strengthen itself, therefore, the sect that occupies the spiritual veins of the Xuanmen has enjoyed all the benefits." The aura of some sects is not abundant, coupled with the consumption of disciples when they cultivate, they can't make ends meet for a period of time, and the aura dissipates at an astonishing speed, and it will soon be exhausted, these sects lose their spiritual veins and quickly decline, alas, the topic is a little farther away, what do you mean? ”

Wang Hao was not sure in his heart, and said tentatively: "I mean, if I create a place full of spiritual energy, will I be able to absorb the spiritual energy around me?" We don't need to use spars to provide energy for a long time, as long as a virtuous circle is formed, a spiritual vein can be formed naturally, and over time, the spiritual vein will gradually grow, which is called once and for all. ”

"There is nothing wrong with the idea, but the feasibility is not high, to form a virtuous circle effect, first of all, the aura must be dense to a certain extent, and it will last for a long time." Chen Xuan had considered this plan before, the spar required was an astronomical amount, and there was still a bottleneck in using the formation, which could be described as difficult, so he automatically gave up.

Wang Hao explained: "Of course you can't use the formation, it's not difficult to let the aura form that scale for a while, the key is to be long-lasting." You have to keep releasing the energy of the hedron, but before the effect is formed, the aura will not only not automatically gather, but will continue to disperse, you

You want to maintain the scale of your energy. You have to continue to burn the crystal, which is the headache. If you use the formation to stop the aura from leaking out, then the aura from the outside will not flow in, and the benign effect will never be formed. ”

"Can it be solved with alchemy?" Chen Xuan asked in disbelief. A few words all spoke to his heart.

"Of course I can, I just need to consider how many spars are used to form this scale, and I can control the process of alchemy as I like, if it is long, if it is short, until the benign effect is formed." Seeing that they still didn't understand, the fat man had no choice but to continue to explain: "First of all, I will melt the spars, completely release the energy, and maintain the alchemy at this stage, as long as I don't condense the pills. The energy has always been in this state, and he can last as long as he wants. ”

The problem that has plagued Chen Xuan for thousands of years is so easy to solve. Chen Xuan smiled bitterly and shook his head. "Where's the hedron? Although I can help you buy it, I can't find much for a while, and it's definitely not enough. ”

"There is no need to worry about the spar problem, the spar in my hand is barely enough." In fact, maintenance is the most important thing, and the scale of energy is a little insufficient. It's just to prolong the time for the effect to form, not to mention that the fat man said that it was barely enough, that is modest, and it should be more than enough. What he was really worried about was another issue.

All spiritual veins have roots, spiritual energy grows on the roots, artificially made spiritual veins have no roots, so they are unstable, but there is nothing now, and when the spiritual veins form a scale in the future, it will be difficult to stop it, God knows where it drifts, maybe it will drift to Shushan. This possibility is very large, you know, Shu Mountain is a blessed land in the world, naturally can attract the surrounding aura, if the spiritual veins created have roots, at most a Shu Mountain to compete for aura, but without roots, it is likely to be attracted to the past, although the process is quite slow, but have to be guarded against.

This is not an alchemy problem that can solve the problem, Wang Hao directly threw the problem to Chen Xuan.

"What's so hard about this, wrap it up on me." Chen Xuan slapped his chest hard, making a thumping sound. For masters who are good at formations, finding a root for the spiritual vein is a piece of cake, and Xingyu can easily handle it.

The Longmen Mountain Range was originally a dragon vein, I don't know why it lost its aura, it is spiritual, as long as you find the location of the dragon's head and apply enough energy, you can restore the dragon vein.

The formation can also fix the aura, but after all, it is not stable enough, doing so is equivalent to finding a dragon vein, there is no trace of the formation at all, but it is natural, no formation wins the formation, this is the highest state of the formation.

That night, a Dan furnace was erected on the cliff north of Caolu, next to the Dan furnace, the fat man added spars unhurriedly, forming spiritual veins is a long process, no matter the day, it is very important to maintain physical strength. Even so, the speed at which the spar was refined was not slow.

The dazzling purple mangs wrapped around the Dan furnace, and the spars put into it quickly melted, and at the same time released golden energy, spreading outward in circles like ripples, covering a radius of 100 meters, wrapped in ripples, as if soaking in warm spring water.

Chen Xuan and Xingyu were both amazed, and Old Man Su lost no time in crossing his legs, closing his eyes and cultivating, and the cultivator encountered abundant aura, just like a hungry child seeing **.

Although there is a good start, the fat man does not dare to take it lightly, this is a huge project, at first it is very simple, just one by one refining spars, but as the number of spars invested, the energy becomes more and more unstable, difficult to control, and to maintain more than 100 spars in a gasification state, this is not a simple matter in itself.

Spiritual energy is the foundation that supports all things, the green beasts, flowers and plants, lucky to be born in a spiritual vein, all have the opportunity to cultivate into refinement, but now the spiritual energy near the grass house is dense to the extent of suffocation, the grass and trees grow wildly at a speed visible to the naked eye, and in the blink of an eye, a lush scene has been formed, with the ears of cultivators, they can even hear the sound of their growth.

However, Wang Hao couldn't laugh at the moment, because he suddenly realized that he had made a very low-level, very fatal mistake, and he had miscalculated the amount of spars consumed.

In the initial stage, the energy released by a spar can cover an area of two or three meters, but with the continuous expansion of energy, covering a radius of hundreds of meters, the situation is completely different, and it is difficult to extend the circle by another meter with more than a dozen spars smashed into it, with the expansion of the coverage area, the number of spars that need to be consumed should not be calculated by simple accumulation, but increased by geometric multiples, and the fat man has not even been in elementary school for a few days, and it is understandable to make this kind of mistake.

"Brother, can you hold on?" Chen Xuan saw that he threw the spar into the Dan furnace vigorously, but the energy wave did not change much, and he also found that the situation was a little inappropriate, but even if the fat man couldn't hold on, he couldn't help much.

"If you can't hold it, you have to hold it!" Wang Hao replied with a sad face, in order not to worry them, he continued: "Don't worry, what I have is a spar that can be smashed, and the fourth-level fire resistance technique is useless. ”

"Are you really okay?" Chen Xuan couldn't see the high spirits on his brother's face, only a trace of melancholy.

"Of course there is something, if I add too many spars and use the fourth-level fire resistance technique, the Dan furnace may not be able to withstand it, hehe." The fat man laughed dryly.
