As soon as Qin Feng finished speaking, Lu Ning's twisted arm returned to normal.

Lu Ning clenched his fist, then looked at Qin Feng and said, "It seems my injuries can also heal."

Wang Qiwen and Qin Feng immediately stopped whispering to each other.

Qin Feng coughed and said, "So it seems that as long as you are injured, healing yourself can also improve your abilities."

At this point, Qin Feng said with some envy, "Since your mental pollution won't worsen, you don't need to worry about the harm of the disease, and your ability development and strengthening speed should be relatively fast."

Lu Ning nodded slightly and said nothing more.

Qin Feng continued his instruction: "The ability enhancement I mentioned before was in-depth development. Next, I'm going to talk about the enhancement of mental strength. This is related to the strength of the awakened one, so let's talk about that first."

"After you awakened your abilities, you should be able to feel your own spiritual power, right?"

Lu Ning and the other three nodded.

For the past few days, Lu Ning has been able to see a ball of white gas circulating in his mind whenever he closes his eyes.

He asked Lin Xiao, who told him that this was his spiritual power after he awakened.

"Scientists began studying the mental radiation emitted by the mist in the early days of the Mist Era, discovering that Awakened Ones also awaken by absorbing mental radiation, and that they can consciously absorb it. After years of research, our Federation has created a mental tempering method suitable for Awakened Ones. This tempering method tempers one's own mental power by absorbing the power of mental radiation."

"Then we divided the awakened ones into nine levels according to the strength of their spiritual power. Levels one to four are low level, levels five to seven are mid level, and levels eight and nine are high level. In addition, there are saints and demigods above level nine."

At this point, Qin Feng paused, a hint of fear appearing in his eyes: "According to the deductions of the experts and the research team, there should be an even higher level above demigods, which is the level of the evil gods worshipped by some cults."

Upon hearing this, Wang Qiwen asked with some curiosity, "Does the Federation currently have this level of authority?"

Qin Feng glanced at Wang Qiwen and shook his head: "No."

Wang Qiwen pursed his lips and remained silent.

Qiu Yuelin then asked, "So, as long as we learn this mental tempering method, we can increase our strength?"

"That's right. However, each level has its own bottleneck. Once you reach the bottleneck, your mental strength can no longer improve. Only by breaking through this obstacle can you continue to improve."

"Then how should we break it?" Wei Xuan asked curiously.

"Everyone's situation is different. Some people break through bottlenecks due to huge mental fluctuations, some break through bottlenecks by persistently using the tempering method, and some break through bottlenecks naturally after relaxing their minds... However, what is certain is that the lower the level of mental pollution, the easier it is to break through the bottleneck."

Upon hearing Qin Feng's words, Wei Xuan and the other two simultaneously looked at Lu Ning.

Wang Qiwen muttered, "Damn... how come he gets all the benefits?"

Qiu Yuelin said with some envy, "Brother Lu Ning is so lucky. He'll probably break through his bottleneck very easily."

Wei Xuan nodded as well.

Qin Feng sighed and said, "You don't need to envy Lu Ning. I've said before that he's special. In fact, Lu Ning is the only human in the entire Federation with a 0% level of mental pollution... Note that I'm talking about all humans from the Mist Era to the present!"

Seeing that Wang Qiwen and the other two were still somewhat dissatisfied, Qin Feng continued, "Alright, next I will teach you the mental tempering method. It's actually very simple. Use your own mental power to sense the mental radiation from the outside world. After sensing it, use your own mental power to absorb the mental radiation from the outside world into your body. Now pay attention!"

At this point, Qin Feng gave the four of them a serious look: "External mental radiation carries mental pollution, so absorbing mental radiation will cause the mental pollution to deepen, the mind will feel pressure, and may even experience hallucinations and inexplicable whispers..."

Wei Xuan and the other two's expressions immediately changed.

Qin Feng seemed not to notice and continued, "Don't panic at this time, because this deepening of mental pollution is temporary. When you feel mental pressure, stop absorbing external mental radiation and start refining the mental radiation you have already absorbed. When this mental radiation is completely refined, the mental pollution will gradually decrease. Only when it decreases to a sufficient level can you continue to absorb it. This process requires slow grinding. Don't rush it, and don't think about taking shortcuts!"

Wang Qiwen asked, "What if I absorb too much mental radiation?"

Qin Feng glanced at him and revealed a lewd smile: "The disease will develop, and before you can cause any damage, we'll kill you and collect your corpse."

Qiu Yuelin's face grew even paler, and Wei Xuan also frowned.

Seeing the atmosphere become somewhat quiet, Qin Feng comforted them, "Don't think too much about it. As long as you're careful, there shouldn't be any danger. Anyway, over the years, I remember no more than five people have become awakened due to mental illness from tempering."

Hearing this, the three of them looked a little better.

As for Lu Ning, his mood remained completely unaffected.

Because it won't affect him.

After teaching the four the methods and key points of tempering mental radiation, Qin Feng said with a lewd smile, "Let's start the first mental tempering here. I'll watch from the side to prevent you from causing any accidents. The rest of today will be used for you to perceive the mental radiation from the outside world."

Wang Qiwen was somewhat dissatisfied: "It's only four o'clock now, why would it take two hours?"
