Ying'er saw Qiu Xin's eyes glowing, and hurriedly stepped forward to ask, "But what did you find?"

"Nope. Qiu Xin said.

Ying'er didn't believe it: "Then why are you so happy?"

"The joy of discovering an unknown substance!" Qiu Xin smiled.

Ying'er muttered, "I'm happy to find the spirit stone!"

Just as she was about to leave, Qiu Xin asked her, "Where is the laboratory?"

"Laboratory?" Ying'er didn't understand.

"It's the laboratory that the refiner needs, isn't it a fantasy if there is no laboratory?"

Ying'er was dumbfounded, and hurriedly went to ask Qianxue for advice. Qianxue consulted with Qiu Xin, and finally decided to add a layer to the Lingquan Pavilion for the study of refining weapons.

To this end, she also spent nearly thirty top-grade spirit stones to purchase equipment and main refining materials for the laboratory, hoping that Qiu Xin could make some great discoveries.

Qiu Xin soon discovered that there was a lack of earth fire here, and some experiments that required extremely high temperatures could not be done for a long time, so he could only occasionally use his own mana to barely maintain it for a while.

In this way, only a large test can be done in more than ten days, and the progress of research is greatly delayed.

Even so, Qiu Xin came up with a conjecture.

The gray mist could be seen but could not perceive its structure, and the magic spirit could not damage it or drive it away. But strangely speaking, it is a creature like a soul eater, which turns into mist when they die, which means that they should be made of mist, at least the core.

Soul Eaters spawned by mist can no longer resist spells, in other words, the structure of Soul Eaters spawned by mist is not stable enough, and they will disintegrate and re-transform into mist when attacked by powerful spells.

In addition, when the space is expanded, the new space seems to be randomly generated, which can be verified from the Lingquan.

What is the reason?Qiu Xin firmly believes that there must be a set of rules behind the seemingly disorder, but she has not yet discovered it.

In the past six months, she has learned about the existence of yin and yang qi from Qianxue, and knows that the Bodhi tree first emits yin and yang qi, and then transforms into the five elements aura.

With this in mind, she put forward a conjecture that every time a linden tree grows a leaf, it emits fluctuations to the outside world, and when these fluctuations come into contact with the mist, they will change violently and give birth to new land.

The fluctuations emit to the edges, touching the mist, and at first the area is very strong enough to generate matter, and then it will slowly weaken, and when it reaches five feet away, it will disappear completely.

No matter has been generated within one to five zhang, but it has caused the structure of the mist to change, forming an invisible spirit devouring beast.

Such a soul devouring beast is not a creature in nature, but just a certain structure, once it smells strong aura fluctuations, it is estimated that it will wake up and break into the space.

Ying'er was only dumbfounded when she heard it, and said: "Girl, you always say that I am open-mouthed, look at Qiu Xin, she is really whimsical!"

Qiu Xin smiled: "What, don't you believe it?"

Ying'er said: "Such an unwarranted assumption, I can just talk nonsense, how can I take it seriously! For example, I can also guess that there is a god living in the Bodhi tree, and after he has eaten and drunk enough, he will let the Bodhi tree grow a leaf to make us happy, and make the space expand a little. When he was upset, he waved his hand and pinched a few spirit devouring beasts to attack us. ”

"Look, isn't my assumption reasonable?" said Ying'er with a smile.

Qiu Xin was stunned and said, "Ying'er, you can really think about it! Why haven't I thought about this layer?"

said with low eyebrows and pondering, as if he was really considering whether what Ying'er said made sense.

Qianxue glared at Ying'er and said, "Qiu Xin, don't listen to her nonsense, she's bragging, don't pay attention to her." ”

"Blow, brag?" Qiu Xin looked demented.

Ying'er smiled: "Girl, I'm just talking about it casually, then I think Qiu Xin will believe it!"

"But, but ......" Qiu Xin still had doubts, since it was speculation, it could be true, not to mention that there was no problem with the logic of the speculation itself.

Qianxue said: "Qiu Xin, what Ying'er said is pure speculation and nonsense. I don't think that's the case with your guess, have you thought of a way to prove it?"

She believed that Qiu Xin would not rashly put forward a conjecture.

Qiu Xin nodded and said, "Well, but it needs a lot of spiritual power support, and I can't verify it with my own mana." ”

"How do I verify?"

"If my conjecture comes true, then the edge of the space will be filled with structures of Spirit Devouring Beasts within five zhang, and as long as there are powerful aura fluctuations, they can be awakened. ”

It must be comparable to the spiritual power fluctuations as strong as that spiritual spring.

The aura fluctuations of the spiritual spring are extremely powerful, and they have not weakened significantly for many years of cultivation, and it is indeed difficult to emit such strong aura fluctuations with the cultivation of the middle stage of the autumn heart foundation alone.

Ying'er took the initiative to ask: "Girl, let me try." ”

The fluctuation of spiritual power exerted by the monks in the Yudan period is not purely determined by the depth of mana, but more by the comprehension of strength.

The three of them came to the edge of the mist, and Qianxue said, "Qiu Xin, you are a little back, if there is really a spirit devouring beast coming out, it is not a joke." ”

Qiu Xin retreated a few feet as she said, and Ying'er took out her two ribbons, with her cultivation in the Dan period, the ribbons soon exerted several times more powerful power than before, and powerful spiritual power fluctuations continued to seep into the mist.

After a while, a wolf howl was suddenly heard, and a wolf's head stretched out of the mist, sniffed around, and went straight to Ying'er.

The strange thing is that this spirit devouring beast only has a wolf head, and the wolf body and wolf feet are all gone, and even the wolf head is vague, and the facial features are extremely unclear.

With a wave of her hand, Ying'er wiped out the vague wolf head and said, "It seems that Qiu Xin's guess is true, but why did only half a wolf head appear?"

Qian Xue said: "It's not that you usually only care about bragging, and you even forget about the business of cultivation?"

When she saw that Ying'er was still using the spiritual weapon used during the foundation building period, she couldn't help frowning, she still had to find a better spiritual weapon for her in the future.

Ying'er said: "Girl, Ying'er's ability to brag has increased a lot, and even Qiu Xin is not suspicious. ”

"You're pretty proud, aren't you?"

Ying'er hurriedly said: "What's the matter, I'm reflecting." ”

Qianxue couldn't hear the reflection in her words at all, so she ignored her, condensed her divine breath in her palm, and turned it into a mass of five elements aura, which fluctuated several times more powerful than Ying'er.

Ying'er was surprised: "The girl's skills are really getting better and better." ”

Qianxue has not stopped cultivating all these years, she carries the mist in the morning, and uses her belongings to cultivate at night.

As the peak master, her monthly offerings are much higher than others, so she has consumed a lot of spirit stones these days to finally save half of the divine breath in the dantian.

According to her previous cultivation experience, she needed to fill the dantian with divine breath and then disperse the veins, and so on countless times before she could practice the third layer of the word-forgetting technique to perfection.

Divine breath is so rare, and it requires a huge amount, but it can make her sad
