The Strongest Qi Refiner

Soon, Fang Yu came to the dark red mountain wall.

When he grabbed two protruding rocks with both hands, he immediately felt a burning sensation and stinging pain.

Even with his current physique, he can still feel the burning. One can imagine... how terrifying the temperature on the surface of this section of the mountain wall is.

Fang Yu climbed up quickly, staying on each rock for no more than two seconds.

However, the higher you climb, the stronger the gravity becomes, forcibly suppressing your speed.

And the degree of heat felt by his hands and feet is getting higher and higher.

"So the test point is right here." Fang Yu thought to himself.

He still maintained a very fast speed and climbed up quickly.

Although he endured a huge amount of gravity and his hands and feet were severely burned, it didn't take him long to climb up more than 500 meters.

In this area, the color of the mountain walls and rocks changes again.

From dark red to pitch black.

As soon as Fang Yu touched the dark rock, he immediately felt a freezing coldness, seeping directly from his hands and feet and impacting his body.

The cold breath penetrated directly into the bones from the outside to the inside.

Just after leaving the hot environment, I immediately entered this extremely cold environment, which can be said to be a world of ice and fire.

The average body cannot bear this kind of temperature alternation and will collapse immediately!

But Fang Yu only took a deep breath and adapted to the cold after a short rest.

He speeded up again and climbed quickly.

"Whoosh whoosh!"

Fang Yu's speed was extremely fast, faster than in the scorching area before!

Because if he doesn't move faster, his hands and feet may become stiff.

And this kind of stiffness progresses continuously. If you are not careful, you may be frozen.

It's interesting to say.

After Fang Yu tempered his body for more than a hundred times, he could rarely feel cold, heat, or even pain in the outside world.

But in the Qiankun Tower, he could feel all of this, and it was the ultimate feeling.

"Ta-ta-ta..."

Fang Yu quickly climbed up, and after spending some time, he finally left the dark area.

In the area further up, the mountain wall appears green.

"What is this? Could poisonous gas be released?" Fang Yu thought for a moment, but didn't think too much.

He had to pass through this area anyway, so no matter what he had to bear, he couldn't avoid it, and there was no point in thinking about it.

"Whoosh!"

Fang Yu kicked off his feet and jumped up more than ten meters, completely entering this area.

At this moment, he was more than 1,500 meters above the ground.

It didn't take long to climb to this height.

"It seems that the test on the fourth level is relatively simple." Fang Yu thought to himself.

When he was thinking this, he grabbed the two protruding green rocks in front of him with both hands, and stepped into the recessed position below with his feet.

"call out!"

But at this moment, he did not encounter the poisonous gas or poison as he imagined, but felt... extreme slippery!

His hands didn't grasp the two rocks, and his feet couldn't step on the sunken spots, so they slipped!

Fang Yu fell backwards, his hands and feet were in the air, and he could no longer grasp any rock!

"Whoosh!"

And the terrifying pressure around him quickly pushed him down.

"Boohoo!"

Fang Yu fell rapidly from the sky.

"Boom!"

Finally, it hit the ground with a loud bang.

A dent was made in the grass by Fang Yu who fell from high altitude.

Lying on the grass, you can see the mountain that is too high to reach the top.

"Master, you have to start all over again." Extreme Cold Tears walked to the side and said with his hands behind his back.

Fang Yu was speechless for a moment and sat up.

He never thought that the difficulty in the green area of ​​the mountain wall was actually the slippery rocks!

I can't catch it at all, and I can't step on it firmly!

Compared with the previous alternating hot and cold, this kind of skating is obviously more difficult!

Because Fang Yu couldn't use his true energy during the climb, he could only climb with his hands and feet.

If the rocks in that area were so slippery, how could he get 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 before, he still didn't see the top of the mountain!

How high is this mountain? !

How long will it take him to climb to the top?

You know, if he accidentally falls down while climbing, he has to start all over again!

"I was wrong, the fourth level is not easy either." Fang Yu stood up and said.

"The tests in the Qiankun Tower will not be easy, Master." Extreme Cold Tears said from behind.

Fang Yu nodded and said, "Now I know."

"Forget it, we just broke through the third level, there's no need to be in such a hurry, let's go out first."

As he spoke, Fang Yu closed his eyes, and his consciousness left the Qiankun Tower.

Opening his eyes again, he returned to reality.

"Boom!"

As soon as Fang Yu opened his eyes, a terrifying amount of magical energy erupted from his body, directly causing the secret rooms in the entire area to explode!
