The yellow sand was flying all over the sky, Mu Fei's body was constantly ravaged by the yellow sand, if it weren't for his own recovery ability, Mu Fei would have been destroyed.

In the area full of yellow sand, as Mu Fei insisted, the strength of his body increased at a terrifying speed.

As Mu Fei entered the deep cultivation, it didn't take long for Mu Fei's physical strength to break through to the level of the highest grade Dao weapon, with the breakthrough of Mu Fei's body, the pain of the yellow sand attack on his body suddenly decreased sharply, if it was comparable to a rain of bullets before, then at most at this moment it was just a slightly larger hail!

When Mu Fei's physical strength broke through to the level of the highest grade Dao device, until the peak of the top grade Dao device, Mu Fei slowly opened his eyes, feeling the yellow sand like spring rain hitting his body, the corners of Mu Fei's mouth rose, this is the feeling, it is so cool!

Facing the yellow sand in the sky, Mu Fei was not afraid, and his feet rushed towards the center of the yellow sand area.

As Mu Fei got closer and closer to the center of the Yellow Sand region, the terrifying gravity pressure was getting stronger and stronger, and the terrifying Yellow Sand attack power was getting stronger and stronger, but fortunately, Mu Fei could still hold on, but even so, Mu Fei's figure was quite embarrassed.

"It's here!" Mu Fei was overjoyed, and he didn't know how long it had been, Mu Fei's figure slowly appeared in the center of the Yellow Sand region.

The center of the Yellow Sand Area is no different from other places, except that gravity and Yellow Sand are a little more terrifying, and the only difference is that the huge stone that stands more than two meters high is erected.

As soon as the boulder appeared in front of Mu Fei, it attracted all Mu Fei's attention, Mu Fei could hardly imagine how hard this boulder was, Mu Fei passed all the way, there was a flat earth everywhere, not to mention stones, in this terrifying yellow sand area, I am afraid that if I throw a mountain in, it can be blown flat!

However, what was in front of Mu Fei's eyes, the appearance of the boulder completely attracted all of Mu Fei's attention.

Seeing the boulder Mu Fei moving forward with difficulty, at this time, Mu Fei's every step was almost using all his strength to act, and I didn't know what was going on in this weird place, the violent yellow sand storm blew the sand and gravel but ignored him, otherwise with Mu Fei's little defense, I was afraid that he would be blown into the sky as soon as he entered the yellow sand area!

One step, two steps......

Mu Fei moved with difficulty, and the distance from the boulder was no more than ten meters at most, but Mu Fei couldn't reach it in nearly half a day!

There is only a distance of one meter, that is, a distance of one meter, but it also stumped Mu Fei, no matter how hard Mu Fei tried, under the terrifying gravity, Mu Fei bowed down and lay on the ground, but he couldn't move, even if Mu Fei moved his fingers at this time, it was extremely difficult.

After trying for a long time, Mu Fei gave up decisively, the pressure around him was enough, I was afraid that I was persevering, my will was not enough, I was afraid that my body would not be able to bear it, feeling the pain of the yellow sand, Mu Fei closed his eyes, and once again urged the power of Dao luck with all his heart, and began to temper his body!

Mu Fei didn't want to give up, so he had to break through again, with Mu Fei's tempering, the shackles of physical strength were quickly broken by Mu Fei, and in the blink of an eye, Mu Fei's physical strength broke through to the ranks of the best Dao weapons.

As Mu Fei's body broke through to the level of the best Dao weapon, there was even a faint trace of purple rush around his body, and the yellow light of the boulder in front of him appeared, directly turning into a streamer and merging into Mu Fei's body, and disappeared behind him in the blink of an eye, all of which Mu Fei was in the joy of breaking through, unaware!

"Where's the stone?" Mu Fei looked towards the stone the moment he opened his eyes, but where was there any stone in front of him, let alone the stone, the gravity disappeared, and the yellow sand in the sky also disappeared, as if everything was a dream!
