His gaze swept over the earth, and after the urging of Jiang Li and Mu Yu, this land polluted by evil qi was almost purified at this time, and even the occasional trace of evil qi in the land would also be purified by the vitality of countless vegetation.

Looking at the surrounding scene, Ling Yun secretly thought, "Hmm...... Although the two of them have joined forces to urge it, the plants here are still a little sparse, and it seems that they need to multiply for a while before they can become dense!"

Looking away from the surrounding landscape, Ling Yun continued to look further into the land. On the surface of the distant land, there is also a layer of green cover. It's just that compared to the two people of Jiang Li and Mu Yu here, the greenery covered on the surface farther away is much thinner than here.

"I don't know when this land will be able to regain its former vitality? Now that life is so scarce, there is more vitality to purify it because of the evil qi pollution in this vicinity, but the place in the distance that has been cleaned up by the soil can only rely on nature to slowly multiply. ”

Thinking of this, Ling Yun took out the Gathering Jar. Carefully looked at the collection of evil gas, this set of evil qi in the collection of evil qi is all he collected, countless evil qi, condensed into a liquid by the collection of evil bottles, turned into a cloud of black gas straight out of the liquid.

"This evil qi ......" Looking at the churning evil qi in the mouth of the bottle, Ling Yun couldn't help but ponder the use of the evil qi: "This evil qi is harmful to life, but it can be used to refine some gadgets. Still, it's best to find a way to convert it. If you can figure out how to transform the evil qi and dead qi, you can also add some spiritual energy to the universe. ”

"And......" Ling Yun looked up at the distant sky, the chaotic mist that enveloped the world had disappeared, although the world was still dark, but there was barely some heavenly light, and it did not keep the world in darkness.

"The chaotic qi that fills the world, although it has been dispelled by Hou Tu Niangniang, these chaotic qi have existed in the world for a long time, and they have long been contaminated with the power of the world, and it is impossible to expel them from the universe again. It must have been shot by Houtu and placed somewhere. If I can figure out how to transform it and help the universe to digest the Chaos Qi, I will definitely be able to gain a lot of merit!"

Retracting his gaze from the distant sky, Ling Yun shook the Gathering Evil Bottle in his hand: "Right now, you can study how to transform evil qi, as long as you succeed, you can carry out the next step of research." ”

When gods and immortals study things, they are different from ordinary people. Immortals have highly efficient magical spells, and their observation of things can go deep to the point of being extremely subtle. Things such as 'a speck of dust hides the world, and half a liter of bell boils mountains and rivers', it is said that the perspective of gods and immortals is different from that of mortals.

With the help of these basic abilities, any immortal god who has reached a certain level can know the nature of an unrecognizable thing by carefully looking at it.

Ling Yun carefully observed the nature of the evil qi, not only the manifestation of the evil qi, but even the fundamental nature of the evil qi was also among his observations.

Through careful research, Ling Yun found that evil qi was a semi-negative vitality compared to positive beings. The reason why it is not an all-negative vitality is because evil energy is also a kind of vitality in the cosmic cycle. If it's all negative energy, then it's going to be in the demonic energy of the opposite side of the universe.

Because of its close to negative nature, the pollution of normal life by evil qi is self-evident, ranging from deformed mutation to debilitation, and at worst, it will wear down vitality and lead to direct death of life.

If it is an immortal god or the like encountering evil qi, if it is blocked from the body, it will be fine, but if it is incorporated into the body, it will pollute the pure essence of the immortal god, which will cause the immortal god to be damaged at least and make the immortal god fall at the worst.

Moreover, because the nature of the evil qi is close to negative, after many cycles of the world, the impurities will accumulate more and more, and this process will gradually accumulate until finally it completely transforms into negative energy.

What Ling Yun wanted to do was to study how to completely reverse the nature of the evil qi and transform it into a positive vitality or aura.

The transformation of the vitality involved in this, the subtlety of creation, is by no means something that can be studied in a short period of time, Ling Yun thought for a while, and had to let go of this idea first.

He put away the bottle with his backhand, and as soon as he raised his eyes, he saw Hongjun looking at him thoughtfully. Before he could speak, Hongjun asked, "Daoyou, do you want to transform evil qi into aura?"

Hearing Hongjun's words, Ling Yun looked stunned for a moment, and then smiled: "I didn't expect Brother Dao to be so keen, I was just thinking about how to transform evil qi into positive aura." Although I have studied the method of transforming the vitality in the past, it is limited to the positive vitality, such as the semi-negative evil qi and the death, but I have not studied it. I don't have a clue how to transform this evil spirit?"

Speaking of this, Ling Yun sighed helplessly.

Lian Lingyun's helplessness fell in Hongjun's eyes, but he couldn't help laughing: "Why didn't Daoyou come to ask me?"

Ling Yun couldn't help but ask in surprise, "Do you know how to transform?"

Hongjun looked at Ling Yun and smiled slightly: "When I was the Emperor's Clan, I was in charge of the Universe Yuan Qi Fortune, and I naturally understood the key to such a transformation. ”

Hearing Hongjun say this, Ling Yun was overjoyed, and couldn't help but say to him: "Please also ask Brother Dao to teach me!"

"This is how it should be!" Hongjun bowed slightly, and carefully pointed out the transformation process of all qi with him.

After his guidance, Ling Yun immediately understood the mystery of the transformation of vitality and vitality. But to understand and understand how to apply it, in order to truly realize the wonderful use. Just like treating sewage, we all know that we need to filter the dirt, but what and how to filter is the real core.

The transformation of vitality pointed out by Hongjun is equivalent to a universal 'formula', which can be applied to many processes of vitality transformation. With this key core, Ling Yun also has some clues about what he wants to study next. It's just that there's still a long way to go before this formula can be translated into practical applications.

But even so, Ling Yun also thanked Hongjun for his generous guidance: "Thank you Brother Dao for your advice!"

"It's okay!" Hongjun waved his hand and said nonchalantly: "After you have cultivated to a certain level, you can actually comprehend the mystery of Yuan Qi transformation, I just told you in advance!"

Ling Yun shook his head and said, "Even if Brother Dao says this, I still have to thank Brother Dao, otherwise if I figure it out on my own, I don't know how long it will take." ”

"Forget it!" Hongjun didn't plan to dwell on this, and planned to change the topic directly: "By the way, it's ...... to talk about" Before his words fell, a bright light suddenly crossed the sky. A deafening whistling sound interrupted Hongjun's words.
