The veins of Tianbo Mountain had indeed stopped running, and Ye Xin, Ni Sheng and the others stood in the magic circle under the main hall, looking around speechlessly.

This magic circle is surprisingly huge, like an endless field, in the middle of the circle is a full of more than 100 meters wide Hua Dan Ding, the role of Hua Dan Ding is to smelt a strange flower and grass that should contain spiritual power into the purest vitality, the vitality will naturally spread outward along the magic circle, and between each Tiangang stone slab that makes up the magic circle, there are very precise grooves, and the Yuan Force will slowly condense into Yuan liquid here.

The circle is circular, and there is a groove around the periphery of the circle, which encircles along the entire circle, which is the lifeline of the main hall of Tianbo, and the yuan liquid will slowly penetrate here, condensing into a stream, flowing around the magic circle, and usually, after three or five years, the yuan essence will appear in the river of the yuan liquid.

For the monks of the Immortal Realm, the Primal Marrow is a kind of root, and it can also be an equivalent exchange.

Whether a sect is strong or not depends largely on the amount of Yuan Marrow produced.

Essence is also produced in nature, but the harvest is very erratic and dangerous, compared to which the output of the veins can be achieved as expected, and the total amount can gradually increase over time.

When Ye Xin came here, he finally understood why Ni Sheng was so angry, and the four star officials of Lu Zongzheng watched the ore veins wither, and he could also reach an understanding from a logical level.

When the previous hall master Wu Tianshou left, he would definitely take all the Yuan Liquid and Yuan Marrow with him, and if Lu Zongzheng wanted to maintain the operation of the Tianbo Mountain vein, he would definitely consume a huge amount of resources.

Now, they need to put pills, strange flowers and herbs into the Hua Danding, so that the refined Yuan Qi can re-nourish this huge magic circle, but if they want the condensed Yuan Liquid to cover all the grooves of the magic circle, they don't know how much it will cost, and when the Yuan Liquid recondenses into a river, that is what he doesn't dare to think about at all.

Ni Sheng and Hua Haoyue walked outside the magic circle to inspect the lifeline, Xiao Demon Finger and the others also spread out, Ye Xin stood in front of Hua Danding, silent.

The things they brought are far from enough, even if the small heavenly realm remains in its original state, and then fill in all the four gods of the millennium, I am afraid that it will not be able to restore the magic circle, because this magic circle is too huge, even if the outer lifeline is excluded, it is just to let the groove of the magic circle condense into the yuan liquid, and the total amount of the yuan liquid can be calculated in 'tons', how many medicinal materials does this need?!

Ghost Thirteen and Zhenzhen stood on Ye Xin's left and right, and they were all thinking about things.

After a moment, Ghost Thirteen suddenly said, "Brother Xin, let me go out." ”

"What do you want to do?" Ye Xin was stunned.

"I want to worship in the Heavenly Phoenix Temple. Ghost Thirteen said with a grin.

"Being an undercover agent?" Ye Xin immediately understood.

"Hmm. Ghost Thirteen nodded and said, "Anyway, it's useless for me to stay here, maybe if I worship in the Tianfeng Temple, I can have another creation!" Brother Xin, do you remember our plan when we were in the Kingdom of David? If I wasn't an undercover agent, it wouldn't be so easy for you to knock out the Iron Heart Saint." ”

"You haven't forgotten him?" Ye Xin sighed softly: "But do you know why you can't forget him all the time?"

"Why?" Ghost Thirteen paused, "Does this have anything to do with what we said?"

"There is a relationship. Ye Xin said, "I won't let you go to the Tianfeng Temple." ”

"You don't agree?" Ghost Thirteen was stunned: "Give me a reason." ”

At this time, the treasure hunting mink swept towards this side like lightning, and there was a butterfly in the corner of its mouth, and Xiao Yue, who was angry, kept spreading her wings and chasing the treasure hunting mink.

Ye Xin frowned and shouted, "What's the trouble?!"

The treasure mink was so frightened that she was shocked, Xiao Yue jumped down from the air, grabbed the neck of the treasure mink, and then picked up the treasure mink, and then she glanced at Ye Xin and said timidly: "Master, don't blame me, the little mink entered here, like crazy, and ran out without seeing it." ”

"What is it in its mouth?butterfly?, where did you catch it?" asked Zhenzhen.

"It's a butterfly, and I don't know where I caught it. Satsuki grabbed the butterfly's wings with her fingers, and the treasure hunter obediently released her mouth and asked Satsuki to remove the butterfly.

"Show me. Zhenzhen said.

Satsuki handed the butterfly to Zhenzhen, who held the butterfly and observed, the butterfly was not dead, its wings were stretched out almost the size of a palm, the color was gorgeous, and there seemed to be a streamer flickering in the butterfly's wings.

"This circle has been unattended for too long. Zhenzhen shook his head: "A place with a strong vitality will always have a strong attraction, and I'm afraid this place has become a paradise for small animals." ”

As if to verify the truth, on the side of Nisheng and Hua Haoyue, a group of butterflies suddenly swept up from the trench and flew into the air one after another.

"There are seals all around the circle, even if they are mixed in, it is easy to clean up, send a hundred and ten people, and it will take less than half a day to clean up. Ghost Thirteen said, and then he looked at Ye Xin again: "Brother Xin, give me a clear word, why don't you let me go?"

"You're not mentally healthy. Ye Xin sighed again: "And I have always believed that the most serious thing in the world that will make the psychology twisted is to go undercover among the enemies." “

"What do you mean? I don't understand. Ghost Thirteen looked suspicious.

"You think, when you go to a strange environment and enter a strange collective, there will always be someone who takes care of you, someone likes you, someone trusts you, someone treats you as a brother, and even entrusts you with their lives, and what you want in your heart is to kill them all, which will cause a great psychological burden. Ye Xin said slowly: "I have seen a very interesting statistic, this situation only lasts for two or three years, it is okay, it has reached more than ten years, many of those undercover agents will become ruthless, there is no way, if you don't suppress your feelings, or you will fail, or you will drive yourself crazy." ”

"Whether it's holding a beautiful ideal, or to fight evil, you can't change this psychological distortion, you already have a problem, if you run to the Tianfeng Temple again, wait until you come back...... I'm afraid it's a complete pervert. ”

"I'm a bad person. Ghost Thirteen said lightly.

"Bad? But you still remember the Iron Heart Saint. Ye Xin smiled.

"He ...... to me is really trusting, only those few times he deliberately messed things up to help you make him angry. Ghost Thirteen let out a soft breath, "But I don't feel sorry for his death. ”

"Only people who are really drunk will say that they are not drunk, and conversely, you think that you are a bad person, which just proves that there is still a soft place in your heart, there is a candle called light, although the candle is constantly shaking by the wind, but you have been trying to protect it and not let it go out completely. Ye Xin said.

"Probably only Brother Xin, you think I'm a good person. Ghost Thirteen laughed.

Ye Xin also smiled, and then grabbed the butterfly from Zhenzhen's hand and handed it to Ghost Thirteen: "Pinch it to death." ”

"Good dear, what are you doing by pinching it to death? Prove that I'm ruthless enough? It's funny...... Brother Xin!" Ghost Thirteen couldn't help but roll his eyes.

Ye Xin took the butterfly back, and with a slight pull of the fingertips of both hands, he tore the butterfly in half, and then he repeatedly stacked the butterfly wings together, then tore them apart, and then folded them again, and finally blew them gently, and countless shiny fragments were scattered downward.

Ghost Thirteen stared blankly at the spilled fragments, he had seen countless bloody rains, and he had also seen Ye Xin's slaughtering methods, but he was used to the battlefield full of blood and fire, but the scene in front of him made him feel the impact.

First, that butterfly is beautiful, and human nature is usually unwilling to destroy the good, and secondly, that butterfly does not pose any threat to them, which is different from the enemies that are surging on the battlefield.

Ghost Thirteen can kill people without blinking, or lie in the grass and watch the squirrel jump around on him with a smile, in fact, there is also cause and effect, because if you don't kill the enemy, the enemy will kill you, so the ghost Thirteen can do it without changing his face and ruthless, but when two lives meet, there is no cause and effect, and he belongs to the powerful side, so there is really no need to hurt.

Looking at the spilled debris, Ghost Thirteen suddenly understood, he subconsciously thought that Ye Xin's request was funny, because he didn't want to hurt anything for no reason.

"Brother Xin, you're not telling me...... You're the real pervert, aren't you?" Ghost Thirteen smiled bitterly.

"I was, and then I came out because of you. Ye Xin said: "So I know best how metamorphosis is refined, listen to me, don't even think about running away secretly!"

"Good ......" Ghost Thirteen shrugged his shoulders, and after saying that, he walked towards Shane and the others.

Looking at the back of Ghost Thirteen, Zhenzhen said in a low voice: "Old Thirteen is indeed a little evil in doing things, but is it that serious?"

"It's okay now. Ye Xin said: "But if you continue to go down, it will be difficult to drag him back, in the past, because I was desperate, I didn't have time to relieve him, but now in the immortal life, I have to watch him." ”

"With me, he won't dare to sneak away. Zhenzhen said, and then she changed the subject: "Do you remember what I said before?

"Remember, what's wrong?" Ye Xin asked.

"You should try it now. Zhenzhen pointed at Hua Danding.

"Me?" Ye Xin looked surprised.

"Your strength is the strongest, of course it's you. "Although the results will not be fast, they will slowly allow you to accumulate experience." ”

"Do you want Hua Danding to refine my Yuan Force?" Ye Xin's eyes widened.

"Little by little, there will be no damage. Zhenzhen said in a low voice: "You let the old thirteen believe in you unconditionally, and now you have to believe in me unconditionally, not to mention that I have comprehended some mental methods in the Sun and Moon Box, which can be handed over to you." ”

"When?" Ye Xin asked.

"Evening, after they're gone. Zhenzhen said.
