The word onlookers is used very accurately, Xu Xingkong guessed that if there was no traffic control from the military here, and there was no cooperation from all parties to block the news, maybe this place would have become a sea of people.

Even so, the surrounding mountains are still crowded with people, Xu Xingkong can't understand who are the people who are leading the children to spread out the picnic cloth and watch, and what are the ideas for coming here, don't they understand that this place seems to be peaceful, but in fact there is still danger?

Without waiting for Xu Xingkong and his party to climb to the top of the mountain, two people hurriedly came down from the mountain, one was wearing a police uniform, and the other was an officer.

The police officer directly ignored Zhang Chaodong and bowed to Xu Xingkong and Lin Xiaofeng, but his appearance in a police uniform and Taoist etiquette was very funny.

The officer saluted Zhang Chaodong, signed up and waited for instructions in a loud voice, and his serious appearance made Zhang Chaodong, the chief, a little embarrassed.

Zhang Chaodong looked at Xu Xingkong, Xu Xingkong smiled and didn't make a sound, Zhang Chaodong asked knowingly, and the officer concisely reported the situation here, in fact, he didn't know what the situation was here, but a huge lake appeared at the end of this barren mountain and wild ridge for no reason, as well as the strange geographical features around the lake, and the strange people who appeared here, all these strange phenomena made him understand that things here are not simple.

However, he is not a scholar and knows discipline, so he just keeps his curiosity in his heart and will never show it, but he can't avoid the eyes of Xu Xingkong and others who are cultivators.

Zhang Chaodong casually encouraged a few words, and then sent the curious officer away, and the officer breathed a sigh of relief and smiled:

"This major is very serious, some things are not easy to say, the disciple is a disciple of the inner sect of Zhongnan Wuji Palace, the elder has specially explained, let me entertain you."

After saying it briefly, he respectfully saluted Zhang Chaodong and Murong Xian, and this action naturally fell in the eyes of the others, and those local or cultivators and demon clans who came from the surrounding area couldn't help but look at this side a few more times.

Of course, even locals who know this police officer do not dare to rush forward, and anyone with a little experience knows that such an unobtrusive approach will not only not bring you benefits, but may also bring disaster at any time.

After the etiquette was completed, the police officer took everyone in a different direction and walked to a nearby mountain, where the mountain peak was higher in elevation, but all the people present were cultivators, and no one cared if the mountain was going to be higher.

Xu Xingkong only then knew that there were so many sects and families in Chang'an, the ancient capital is the ancient capital, and the things that have been precipitated over the years are really not comparable to the emerging cities of Pengcheng, however, from another point of view, Pengcheng is light, full of vitality and innovative spirit, and the advantages in this regard are not comparable to Chang'an.

After a while, everyone came to the top of the mountain, which had been chartered by Zhongnan Wuji Palace, but now in addition to Xu Xingkong and his party, there was only a group of very young disciples, standing a little below the mountain peak under the leadership of the division commander, looking at the lake not far away and pointing.

That's right, it's a lake.

Xuanyi Taoist is not wrong, yesterday when Xu Xingkong left it was still a smooth big round pit, overnight, this is already an irregular edge of the lake, due to the surface elevation is inconsistent, so the groundwater flooded up after the original clear pre-round pit boundary, turned into an irregular lake.

Lin Xiaotong blinked, turned back to Xu Xingkong with a smile:

"You're just taking us to see the lake?"

Xu Xingkong pinched his chin, it seemed that this lake was really nothing to look at

Lu Wuxiang smiled secretly and said:

"Sister, pay attention to the mountain part by the lake, not those landslides, but those rocky faces."

Lin Xiaotong had actually noticed it a long time ago, she just deliberately said this to embarrass Xu Xingkong, seeing Lu Wuxiang speak, she glanced at Xu Xingkong with a smile, held Lu Wuxiang's shoulder, and observed the mountain rock face in the distance that could almost be used as a mirror.

Xu Xingkong coughed dryly, raised his hand and drew a circle:

"Yesterday it was a huge round pit, and as you can imagine from the rock mirrors, it was very regular and round, as if something had dug a piece directly out of this space, and all the material in this round pit disappeared out of thin air."

Lu Wuxiang broke away from Lin Xiaotong's arm, turned his head to look at Xu Xingkong and asked:

"Brother Xu, where did all those substances go? Doesn't it say that energy is conserved? ”

Xu Xingkong nodded:

"Energy must be conserved, and these substances are just compressed, that is, the atomic structure is destroyed, so that a large piece of matter becomes a very small piece."

Lu Wuxiang blinked her eyes and asked curiously:

"What about this one? Did it sink into the ground because it was too heavy? Could such a thing be caused by gravity to destroy the surrounding atomic structure, causing a chain reaction? ”

Xu Xingkong shook his head with a smile:

"How can there be a ripple effect? If that's the case, who would dare to stand here and watch the excitement. ”

At this time, Lin Xiaofeng also spoke:

"Wuxiang, you are also a child of a cultivation family, how could you not know that the quality of the materials used in some spiritual weapons is also very huge, but the finished product is very small, and you can't feel any special weight when you use it, what is the reason for this?"

Lu Wuxiang suddenly:

"Ah, I forgot, it's the Yuan Spirit and the Circle! However, how could such a large piece of ordinary substance, and it was still a mess, be refined into a spiritual weapon? What's more, there is no one to refine at all! ”

This question also aroused Lin Xiaotong's interest, and of course He Yan also wanted to know the answer to this question, but there was no part for her to speak here, she was very conscious of being her background board, but her ears were stretched out.

Lin Xiaofeng smiled but didn't answer, but turned his head to look at the group of young disciples of Wuji Palace not far away, and a middle-aged man who was leading them.

"It just so happens that they're asking the same question, so let's hear what others have to say."

After Lin Xiaofeng finished speaking, he turned his head to look at Xu Xingkong, Xu Xingkong raised his hand knowingly and released a spell, and a clear voice suddenly came from everyone's ears.

“... Yang Hui's question is very good, such a large piece of mixed matter must not be directly refined, but we have just discussed that the inward collapse caused by the rampage of the magic circle has destroyed the atomic structure of matter, that is to say, these substances are no longer hydrogen, oxygen, carbon, calcium, etc., but piles of neutron protons and electrons, that is, the essence is actually a unified element. ”

Lu Wuxiang suddenly, the first problem was solved, but if no one refined it, how could this mass of matter become a spiritual weapon?

At this time, Xu Xingkong cut off the spell just now, glanced at Lin Xiaotong, Lu Wuxiang, and He Yan with a smile and asked:

"So, you might as well think about it, how did this mass of matter become a spiritual weapon? Speaking of which, such a compressed mass of matter is actually a good matrix. ”

Lu Wuxiang frowned, biting her lip and thinking, Lin Xiaotong rolled her eyes, obviously, she didn't think that she could get the answer by relying on her own thinking, but she couldn't see the answer from Xu Xingkong or her sister's face, and she wanted to run to eavesdrop on the explanation of the Wuji Palace teacher, but she was afraid that Xu Xingkong would blame, so she had to pout and stare at Xu Xingkong dissatisfied.

Xu Xingkong shrugged his shoulders, looked at He Yan again and asked:

"He Yan, what do you think?"

He Yan was a little flattered when she heard this, but she really didn't know this question, she just started learning, but Xu Xingkong asked, she had to answer again, He Yan's eyes rolled, and she understood that Xu Xingkong certainly didn't want to embarrass her, so it must be reasonable for him to ask.

"Well... Could it be natural? I remember you once told me that all spells and magic circle theories are actually learned from nature, so under certain conditions, will the power of nature spontaneously form spiritual weapons... This? ”

The more He Yan spoke, the more empty her heart became, because the eyes of everyone looking at her became more and more strange, and the last word He Yan's voice was so small that she could hardly hear it.

Before Xu Xingkong could speak, Lu Wuxiang was the first to exclaim:

"That's right! Sister He Yan, you are so smart, that's right, that's it, it's a naturally formed spirit weapon, this is an innate spirit treasure, right, Brother Xu? ”

Xu Xingkong looked at He Yan appreciatively, and glanced at Lin Xiaotong helplessly, Lin Xiaotong pursed his lips and avoided Xu Xingkong's gaze.

"Wuxiang is right, although He Yan has not studied systematically, but her imagination is very good, you remember, although you are a halfway monk, but halfway to become a monk has the advantage of being a halfway monk, that is, there are no rules and regulations in your head, and you must give full play to this advantage."

Lin Xiaotong pursed her lips and muttered in a sour whisper, but she was not discouraged, and after a while, she raised her head and listened carefully to Xu Xingkong's explanation.

"In fact, if we use the concept of spiritual weapons, we will find such a surprising truth, the natural world itself is the largest spiritual treasure, therefore, within the scope of this spiritual treasure, all the energy and the operation of the primordial spirit should follow the rules of this spiritual treasure in this natural world."

"Therefore, when the collapse caused by the artificial black hole occurs, this rule may be broken, therefore, the rule will automatically come out to maintain and correct, plus the formation of the collapse itself is caused by the magic circle, the foundation of the magic circle is order, that is, the rules, the two are added, the dangerous collapse is sealed, forming a natural spiritual treasure."

Xu Xingkong patiently explained, and everyone nodded suddenly, even Murong Xian couldn't help but nod lightly, showing a knowing and joyful smile.

The same smiles and exclamations also came from the children not far away, and it seemed that the master of the Wuji Palace was still very capable.
