"Grandpa Xue, then let's start quickly!" Yan Fei was already a little impatient, the most urgent thing for him at the moment was to raise his strength to an upper-level battle master, although it sounded a little far away, but at this time, Yan Fei's heart was also full of fighting spirit.

Xue Feng looked around, it was the end of spring at this time, and there were scattered green grass growing on the originally barren plain.

"Fei'er, I asked you to carefully sense the spiritual power of the surrounding heaven and earth in the Mist Forest before, do you remember this incident?" Xue Feng looked at Yan Fei suspiciously and asked.

"Remember!" Yan Fei nodded affirmatively, although Yan Fei did not witness the endless spiritual power coming towards him at that time, but it left indelible traces in his mind, colorful air currents, like clouds floating in the sky, converged in his mind, and later, Yan Fei only felt an incomparably powerful wind current, blowing away those air currents.

"Just remember, then let's start now!Fei'er, now I'll let you go back to the original state, can you do it?" Xue Feng looked up at the sky, then looked at Yan Fei on the side and asked.

"I'll try!" Yan Fei didn't hesitate, and after thinking about it slightly, he closed his eyes.

It is also strange to say, the originally sunny weather at this time, it is said to change, the dark clouds do not know when, it actually rushed from the sky, and above Yan Fei's head was an incomparably bright sky, surrounded by dense dark clouds colliding with each other, there were lightning bolts, and then the deafening thunder also came from far and near in the sky.

Xue Feng smiled slightly, as if he was very satisfied with the arrangement of the heavens, while Yan Fei, who had his eyes closed, stood straight in place, not moving, and there was a tendency of Mount Tai collapsing in front of him without moving.

In just a short time, raindrops the size of beans fell from the sky. In an instant, the majestic rain swept the entire desert, such weather should not have appeared in the endless desert, but there is such a coincidence in the world, it, it did happen.

The rain became heavier and heavier, and the rain lines that were pulled up from the sky to the ground became denser and denser, like a large pearl that had fallen from the sky.

The lightning in the sky became brighter and brighter, the thunder became louder and louder, and the wind began to sweep up, and for a while, the sound of wind, rain, thunder, and lightning began to drink in unison, waving together in the black and oppressive sky.

Xue Feng and Yan Fei's clothes had been soaked by the rain, and there was a hazy mist around them, adding an unknown sense of depression to the atmosphere at this time.

Yan Fei still stood still, but in his heart, he was trying to bring himself back to the original scene.

Suddenly, Yan Fei was overjoyed, and in his mind, several colored air currents appeared again, how dare Yan Fei hesitate and continue to maintain this state. Although the desert at this time was already full of wind, rain, thunder and lightning, Yan Fei didn't feel it at all, and still tried his best to sense the aura of heaven and earth around him.

Xue Feng looked up again, and at this glance, even Xue Feng, a powerful person, was surprised. The wind in the sky stopped, but instead turned into gray ribbons, and began to run towards Yan Fei. The sound of thunder and lightning also stopped, turning into a blue and white air mass, and rushed towards Yan Fei with great momentum. The original pouring rain had dissipated, and the endless pearl particles began to rise from the ground, slowly merging together, and from a distance, it looked like a pool of water floating in the air, and this pool actually flew towards Yan Fei.

"It's incredible! It's the most powerful aura combination I've ever seen in my life. I really don't know what is so special about this kid Yan Fei, he has such a perverted spiritual power affinity!" Xue Feng admired vigorously on the side, although his strength was already very strong, but he had never seen such a momentum, wind, rain, thunder and lightning rushed from all directions, just like Chaohe.

Immediately after, the wind arrived first, and I saw that the crystal screen instantly submerged Yan Fei. Xue Feng dodged, then jumped to the side, quietly staring at the qiē in front of him.

At this time, Yan Fei only felt as if he was wrapped in an invisible force, and the strange force seemed to be still binding him, getting tighter and tighter, and Yan Fei was almost out of breath.

Then, Yan Fei only felt that two more air currents surrounded him, and Yan Fei's whole body trembled the moment he was impacted by these two air currents.

This is Yan Fei's only feeling now, Yan Fei only feels as if he suddenly has some more strength in his body, and all kinds of pain attack Yan Fei one after another, Yan Fei only feels that he is so alive and dead at this moment.

Suddenly, an invisible force descended on Yan Fei's body again, and Yan Fei's already painful body couldn't help but endure even more pain.

"Ahh

Yan Fei's eyes were still tightly closed, and despite the endless pain, he still persevered, and his eyes never opened.

Xue Feng on the side was also a little unbearable, but he didn't want to wake Yan Fei up from such a state.

"Fei'er, hold on, as long as you can pass this level, you will at least be a four-star fighter. Xue Feng said softly, he didn't expect that just now, Yan Fei would be able to attract so much spiritual power, as long as Yan Fei could convert those spiritual powers into battle qi, then Yan Fei would be able to step into a four-star fighter.

In Xue Feng's memory, none of the people who had just stepped on the path of cultivation could attract so much spiritual power at one time.

Then, Xue Feng's legs bent slightly, and the whole person sat on the ground, slowly closing his eyes, Xue Feng didn't want to see Yan Fei's painful appearance, the only thing he could do was to ignore it like this and leave it alone.

Time passed quietly, and in the blink of an eye, it was two months, and the weather above the desert became normal, but there were still four different spiritual powers around Yan Fei, but at this time, those spiritual powers had become a lot rarer.

Another month had passed, and at this time, there was still the last wisp of spiritual power floating in front of Yan Fei.

"Is it going to be over?" Xue Feng opened his eyes and said to himself as Yan Fei, who was still standing.

After a while, the last wisp of spiritual power disappeared in an instant, but Yan Fei's cheeks trembled slightly, and then, Yan Fei opened his shining eyes.

"Fei'er! Congratulations!" Xue Feng stood up and walked up to Yan Fei and said excitedly.

Yan Fei seems to have changed a lot during this time, and there seems to be a trace of lightning in his eyes. Yan Fei's mind sank, and he found that in his body, there were actually four bright star clusters suspended.
