Soon, Fang Yu arrived at the location of that dark red mountain wall.
When he grabbed two protruding rocks with both hands, there was a burning sensation and a stinging pain.
Even with his current physique, he could still feel the burning. You can imagine how terrifying the temperature on the surface of this mountain wall is.
Fang Yu quickly climbed up and stayed on each rock for no more than two seconds.
However, the more you climbed up, the more you became, the more you became stronger and the speed was suppressed.
And the heat felt by hands and feet is getting higher and higher.
"So the test point is here." Fang Yu thought to himself.
He still maintained a very rapid speed and climbed up quickly.
Although he had suffered a great amount of gravity and was still burned with both hands and feet, it still didn't take him too long to climb up more than 500 meters.
In this area, the color of the mountain walls and rocks changed again.
From dark red to pitch-black.
As soon as Fang Yu touched the dark mountain rock, he immediately felt a cold chill, and directly penetrated into his hands and feet, impacting his body.
The cold breath penetrates directly into the bones from the outside to the inside.
As soon as you left the hot environment and immediately entered this extremely cold environment, it can be said to be a world of ice and fire.
This kind of temperature alternation can't stand the ordinary body at all and will collapse directly!
But Fang Yu only took a deep breath after a short rest and adapted to the coldness.
He speeds up again and climbs up quickly.
"Swoosh swish swish!"
Fang Yu's speed is extremely fast, faster than before in the scorching area!
Because if he is not quicker, his hands and feet may be stiff.
This kind of stiffness continues to progress, and if you are not careful, you may be frozen.
It's also interesting to say.
After Fang Yu's body quenching for more than a hundred times, he rarely felt it in the outside world, whether it was cold or hot, or even pain.
But in the Qiankun Tower, he could feel all this, and it was the ultimate feeling.
"Dadada..."
Fang Yu quickly climbed up, and after a while, he finally left the dark area.
And further up, the mountain walls appear in turquoise green.
"What is this? Could there be poisonous gas released?" Fang Yu thought for a while, but didn't think too much.
Anyway, he had to pass through this area, so he couldn't avoid it no matter what he had to bear, and it was useless to think about it.
"Swoosh!"
Fang Yu kicked his feet and jumped up more than ten meters, completely entering this area.
At this moment, he was more than 1,500 meters away from the ground.
It doesn't take too long to climb to this height.
"It seems that the test of the fourth level is relatively simple." Fang Yu thought to himself.
When he thought about this, he grabbed the two green rocks protruding in front with his hands, and stepped into the concave position below.
"call out!"
But at this moment, he did not encounter the poisonous gas or poison he imagined, but felt... the ultimate slippery!
His hands didn't grab the two rocks, and his feet couldn't stand the sunken position, and he slipped directly!
Fang Yu fell backwards, his hands and feet were already in the air, and he could no longer catch any rock!
"Swoosh!"
The terrifying pressure around him quickly pushed him down.
"Swish swish swish!"
Fang Yu fell rapidly from the sky.
"Bang Long!"
Finally, it hit the ground and made a loud bang.
The grass was smashed into a pit by Fang Yu who fell from a high altitude.
Lying on the grass, I saw the mountain that was so high that it was not visible to the top.
"Master, you have to start over again." Ji Han Zhilei walked aside, said with his hands behind his back.
Fang Yu was speechless for a moment and sat up.
He never expected that the difficulty of the green area of the mountain wall was actually the slippery rock!
I can't catch it at all, and I can't step on it!
Compared to the previous alternation of hot and cold, this slip is obviously more difficult!
Because Fang Yu cannot use true energy during the climbing process, he can only climb with both hands and feet.
If the rocks in that area were so slippery, how would he pass through that area?
That area is at least five hundred meters high!
Another key point is that even though Fang Yu had climbed to a height of 1,500 meters, he still didn't see the top of the mountain!
How high is this mountain?!
How long does it take for him to climb to the top?
You know, if he doesn't pay attention to falling while climbing up, he has to start over again!
"I was wrong, the fourth floor is not simple either." Fang Yu stood up and said.
"The tests in the Qiankun Tower will not be simple, Master." Ji Han Zhixiong said behind him.
Fang Yu nodded and said, "Now I understand."
"Forget it, I just broke through the third level, there is no need to be so anxious, let's go out first."
While speaking, Fang Yu closed his eyes and his consciousness was separated from the Qiankun Tower.
Opening his eyes again, he returned to reality.
"Boom!"
As soon as Fang Yu opened his eyes, a terrifying magic energy burst out from his body, which directly shocked the secret room in the entire area!
