In the next few days, Li Feng had been thinking about this matter, no matter what, he must have doubts about Song Sangang, this person always left him with a feeling of hiding a lot of things, no matter how he thought about it, he couldn't count on him.

"Alas...... I haven't figured out some of the details, but now I can't afford to wait any longer, and there are only about three days left until the seal is lifted. Li Feng walked on the lower floor of the Ice Cold Palace, thinking about it.

Although this layer is still a little cold for him now, there is no problem at all if he cultivates as usual here, and it can just be used to provide Li Feng with a place for no one to disturb.

"This trip is more auspicious...... It seems that I can only delay until the day when the seal is about to be broken, and this is the most certain. Li Feng couldn't help but clench his fists, and his nervousness was self-evident.

......

"Three days later?" After Song Sangang heard Li Feng's words, he lowered his head and thought for a while, and after a few seconds, he raised his head and said, "Okay, let's go to Mentor Zhang's door at that moment when the sun rises in three days." ”

"Okay!" Li Feng also nodded, not forgetting to take another look at Song Sangang's expression, hoping to find a trace of dissatisfaction, but until the two were about to completely separate, he still found nothing.

"I can't guess what he's thinking......"

In the past three days, Li Feng has been grinding himself like crazy, and after three days, it is not only the day of assassination, but also the day he is going to leave Linghan Academy, so before that, he must make good use of the resources in it.

The lower layer of the Ice Cold Palace has almost become his permanent place, and he has been able to fully withstand this severe cold, almost regard this place as his second residence, and he is cultivating all the time, and his physical strength has completely entered the body of the Void Cave, and that layer of frost armor can also be controlled and switched freely.

In addition, the place where Li Feng is going is of course the Linghan Tower next door.

Since he only had three days left, and the Spirit Cold Tower couldn't go every day, there was a three-hour time limit, so he only had the last three hours to go inside to comprehend.

"I must understand all the third layer of this Linghan Tower!" This is the promise and goal that Li Feng made before entering the next day.

The strong man guarding the door next to him accidentally heard it, and sneered:

"Little brother, although you are really strong now, I have also seen the entry and exit in and out of the past month, but if you want to give the third layer all to the understanding, it is a bit of a joke, with your current cultivation to be able to go to the third layer, it is already very strong, and it is better to talk less about this kind of thing, it will attract the disdain of others. ”

Li Feng smiled at the big man guarding the door, and didn't say anything, he was a middle-level mage in their eyes, according to normal rules, indeed, it was already an exaggeration to be able to enter the third layer.

However, Li Feng is not a middle-level mage, and his perception at the high level is not comparable to that of his peers, after nearly two months of entering and exiting, a total of about seventeen or eighteen entries, the third layer has almost been thoroughly explored by him!

There are probably more than a few hundred murals on the third floor, if you only look at the wind and thunder elements, you have to remove two-thirds of the number, plus some general murals, there are probably more than a hundred that Li Feng needs.

And the three hours he entered each time were not as laborious as the students who were taking exams in ordinary schools, and they were so hard to deduct one paper after another.

With an inherently excellent foundation and an extremely outstanding talent for perception, Li Feng's speed at cracking these murals was quite fast! Inadvertently, Li Feng might have completed this extremely profound mural in front of him.

Therefore, at his speed, it took nearly two months to fully understand the third layer, but it was not just talk.

This last chance, there are only ten murals left for him......

Don't look at this small number, each one can only be barely cracked by a mage who has reached the peak of a high-level cultivation normally, and it still takes a lot of time to accumulate.

Therefore, Li Feng's challenge today is definitely not low, if he doesn't crack it all within three hours, he will definitely have regrets.

"So...... Let's start!" Li Feng twisted his neck, rubbed his shoulders, and after making all the preparations, he devoted himself to the process of cracking the mural.

An hour had passed, and he was in excellent condition to complete four paintings that others would have taken a day to see.

Two hours passed, and according to the increasing difficulty, Li Feng also finished the next three well, and in the end, the extremely difficult three also required him to complete in an hour, which was simply impossible for earthlings to do!

However, Li Feng ...... It's impossible to say if he's an earthling.

"Huh~~~" took a deep breath, Li Feng emptied all his brains at this moment, leaving only the knowledge and experience of the Elemental Perception year.

In this way, he is almost free of any distractions, pure and flawless, and has no distractions, and it is appropriate to say that he is a pure child!

The soul seemed to have entered another world, and his eyes were extremely focused on the content on the mural, and his spirit was highly concentrated, causing his eyes, his pupils, to seep out a dazzling golden yellow!

"That's ...... Again...... There you go!"

Twenty minutes have passed, Li Feng has completed the penultimate mural, this speed is actually terrifyingly fast, but the difficulty behind it will be higher and greater, he goes on like this, the penultimate one still has a chance, but the last one ...... There is little hope.

At this time, a state called absolute concentration gradually emerged in Li Feng, and he began to forget where he was, forgot the students around him who were also contemplating, and forgot who his surname was, only remembering ...... I'm going to figure out all the remaining two murals!

"Alright...... There is only one last step left. Muttering, Li Feng had also lost track of time, and the only thing he had to do was to figure out the last one, a wonderful mural created by the joint efforts of several super-level mages.

At this time, there are only twelve minutes left.

At this moment, the voice had no meaning to him, and a fire had already ignited in Li Feng's heart, it was the flame of fighting spirit, the flame of spirit burning!

That's right, his mental power is undergoing some qualitative changes, the emotions of perseverance, the emotions of stubbornness to complete, and a large number of emotions expressing anxiety, constantly fermenting in his mind.

The person closest to Li Feng was still studying the mural he was looking at, but somehow, he suddenly felt uneasy, as if he couldn't calm down.

The most important thing is that he inexplicably feels that he is in a hurry, obviously he has just come in, and there should be nothing to worry about, but he just can't sink down.

"It's ...... What's going on? I'm so irritable!"

Another power in Li Feng's body seemed to be being indexed, and it incited the emotions of the people around him and strengthened Li Feng's spiritual power.

If someone looks at Li Feng's eyes with a straight face, they will find that his left eye is already covered with golden light, and his right eye is also gradually shining, and around his body, there is an invisible aura, that invisible power, like sublimation.

Time passed little by little, and Li Feng was getting stronger little by little, and this so-called getting stronger refers to his spiritual power, even ...... His spiritual realm!

That's right, the spiritual realm is divided into seven layers, and Li Feng has seen the highest number of layers in the spiritual realm at present, Du Hao, who was unexpectedly transformed into the third layer of the spiritual realm because of the stimulation of a ranking competition of the same level.

It can be said that at this level, it is difficult to find a guy on the earth who will be taller than you in this regard, and in the face of ordinary people, martial artists without any spiritual power can even interfere with their actions, and the negative impact on themselves will be greatly reduced.

Time was running out, and Li Feng was still studying, his vision had even begun to blur, but the process of analysis still hadn't stopped in his mind.

Maybe it is the blessing of the pure heart, or the power of emotions that is influencing something, Li Feng's mind was originally a space that could no longer fit the analysis steps, but now this space has suddenly become larger, leaving a very useful territory, which allows Li Feng to have the brain power to continue to comprehend this mural.

After adapting to this new intensity of spiritual power, Li Feng's consciousness gradually sobered up, his vision slowly became clearer, and his mind gradually had a careful process of arrangement, and this originally difficult mural seemed to be no longer a problem.

"Jingle ~~"

"Jingle ~~"

The alarm in the storage bag had already sounded, urging Li Feng to leave the Spirit Cold Tower, but Li Feng had no intention of leaving.

This alarm sound was specially set by the super-level mage of the academy's middle music department, and it had little impact on the people around him, but it was extremely disturbing to his own thinking.

This is also to prevent someone from plugging in earplugs and continuing to stay in a shameless manner, with this alarm bell, you can't feel at ease what you want to do inside.

But Li Feng was in a state of absolute concentration, and under the maintenance of this state, he was not affected by any external influence, and he couldn't even hear the obvious alarm bell!

Thereupon...... Without anyone knowing, Li Feng did something that no one had done before, and he left for more than ten minutes with a delay......

When the alarm bell rang for more than ten minutes, Li Feng finally heard it, but he didn't leave immediately, but slowly stood up, his expression was full of excitement, and he couldn't help clapping his hands and said:

"It's wonderful...... Under admiration admiration...... I see, I see!"

"After being promoted to the third level of the spiritual realm, I finally realized it!"
