Next, Yun Yi ran again, but this time it was different from running with his head covered, and he also observed the surrounding environment by the way when he ran. He found that as he ran, countless extremely small transparent balls of light surrounded him, and a very small part of them attached to him and merged with him. "What is this?" Yun Yi stopped, reaching out to touch it, but the ball of light suddenly disappeared. Yun Yi frowned, recalling the details of his previous running: although he used to run with his head bored, he had never seen such a thing when he occasionally raised his head to look at the road.

"I don't know, forget it, keep running" Yun Yi thought to himself.

Yun Yi ran again. He continued to observe the changes around his body as he ran. Sure enough, the tiny ball of light that had just disappeared came out of thin air from under Yun Yi's feet again, and as Yun Yi's footsteps accelerated, the number of light balls gathered more and more, but after that, no matter how Yun Yi changed his pace, these balls of light were always just around him, only occasionally one or two attached to his body and then disappeared, Yun Yi shook his whole body vigorously, trying to "scare away" these balls of light, but the ball of light seemed to follow him, that is, they surrounded him and did not leave.

After running like this for about an hour, Yun Yi stopped again, because he found a fact: these balls of light had become a little larger, and their color had changed from transparent to a faint yellow.

"These things ......" Yun Yi looked at these pale yellow balls of light and frowned.

At this time, a cloud of mist behind him slowly transformed into a human form, and this person was none other than the Qi Sect!

"How's it going? Why don't you run away?" asked the Airbender with a smile.

"Grandmaster, I saw something strange. Yun Yi came over and said.

"Something. "The Qi Sect is interested.

"Some little yellow balls of light, it appeared as soon as I ran. Yun Yi said truthfully.

"Oh?" Qi Zong's face moved slightly, but he quickly returned to normal. Then he calmly said, "Is there anything else?"

Yun Yi has been staring at him, and these changes in his expression are also seen by Yun Yi.

"No," Yun Yi replied, "Do you know anything?"

"It's nothing," Qi Sect said lightly, "These balls of light are actually the natural energy here, but they are invisible to ordinary people, and can only be seen by those who have opened the 'Qi Gathering' stage." ”

"So, I've reached the 'gathering of energy' stage. Yun Yi said ecstatically.

"You're still far away, reaching the 'Qi Gathering Period' normally requires at least 3 months of uninterrupted cultivation. Because the spiritual energy of this mountain is very sufficient, a month and a half of cultivation is enough. You've just got the hang of it, and you're still far from the real 'gathering of energy' period. Qi Zong poured a basin of cold water on him.

"What is the real gathering period?" Yun Yi asked.

"The real 'Qi Gathering' period will not only greatly improve the functions of your body and enlighten your spiritual intelligence, but also allow you to see the hidden natural energy around you, the light ball you are talking about has become larger, in fact, you can see the hidden deeper natural energy, if it is a person in the 'Qi Extinguishing' period, he can even see the natural energy 3 kilometers away. Qi Zong said.

"Then what's the use of these natural energies?" Yun Yi thought of another question.

"Of course it works, these natural energies can not only strengthen your body, increase your strength, but also extend your lifespan, and even allow your body to be reborn, for example: a person in the late stage of 'explosion', even if his arm is broken, he can grow back. Qi Zong said lightly.

"So powerful" After listening to Qi Zong's description, Yun Yi couldn't help but smack his tongue secretly.

"Not only that, some strong people who have reached the late stage of 'Qi Extinguishment' can also freely manipulate the huge natural energy in the natural world for their own use, such as thunder and lightning, and flames, and some can also be invisible, and it is common for them to take people's heads silently. The Qi Sect once again said something that shocked Yun Yi

"This is also too domineering, isn't there no opponent for the powerhouse in the 'Qi Extinguishing' period?" Yun Yi frowned.

"Hahahaha, how can there be no opponent, one thing descends one thing, everything has a nemesis, you think that the invincible existence may be a sheep with slaughter in other eyes. Qi Zong laughed.

"That's too" Yun Yi quietly raised his head and glanced at the laughing Qi Sect, thinking: A pervert like you, it is estimated that a strong person above the 'Qi Extinguishing' period will not take it seriously.

"Okay, if you don't have any other problems, you can continue to cultivate, I don't think you're far from 'gathering qi'. Qi Sect waved his hand at him and said.

"No, I have to go back. Yun Yi said, "I've been here for too long, and if I keep sleeping, the people in my dormitory will be suspicious." ”

"Well, it's okay, you can go back first, and come back tomorrow night to practice. Qi Zong thought about it and said to him with a serious face.

"Alright, then I'll go, Grandmaster. Yun Yi said goodbye to the Qi Sect and was about to leave, but found one thing - he didn't know how to get out of here.

"Well, Grandmaster, how do you get out of here?" Yun Yi said with an embarrassed expression.

Airbender didn't speak, but drew a golden circle in the void in front of him with his hand, and the scene in the dormitory appeared in the circle. Qi Zong motioned to Yun Yi with his eyes to let him in.

"You go in, remember, if you want to enter this Sumeru space in the future, you should silently recite "qi" in your heart, and then put your hands together, if you want to leave from this space, just recite the word "go back" in your heart, and there will be a period later. After saying that, the Qi Sect waved his hand and disappeared.

"There will be a period later. Yun Yi knew that this harvest in the Sumeru space would change his fate.
