"Ladder?"

Seeing the narrow ladder, Shang Shan was stunned.

Then he was surprised and asked, "childe Cheng, how did you find out?"

"Intuition."

Cheng Feng's ability to find this ladder does have intuitive factors.

But the main reason is his sharp and unparalleled God's eyes.

God's eyes can see clearly, although the floor covered on the ladder looks no problem.

But under the eyes of the God of creation, there are many loopholes, which are very conspicuous.

Then Cheng Feng picked it with a knife and immediately found the clue.

"Come on, go down and have a look."

With the eyes of the God of creation, he looked into the ladder, but because his sight was blocked, he couldn't see anything.

So Cheng Feng said hello and went down the stairs first.

The Shangshan spirit looked at Cheng Feng with a strange look, and then stepped into the ladder.

The ladder was not long. Cheng Feng took a few steps and came to the end of the ladder.

At the end of the ladder is a depression with a radius of more than ten meters.

In the center of the depression, there is a muddy spring.

The spring water exudes a fishy smell, giving people a feeling of extreme danger.

"It seems to be... Yellow spring water!"

At the moment of seeing the turbid spring water, Shang Shanling said with horror.

"Yellow spring water?" Cheng Feng doesn't know much.

"Yellow spring water is said to be a big river flowing in front of hell."

Shang Shanling said, "that river is terrible and can melt everything in the world. Even the strong ones who ascend to heaven will fall if they fall into it."

"It is estimated that Pei Xiao bought this yellow spring water from hell gate at a great cost."

"The purpose should be to refine flower poison."

"Can you purify flower poison with yellow spring water? Pei Xiao can think of it."

Cheng Feng was slightly surprised: "but I guess this Wang huangquan water should have been diluted, not pure huangquan water."

"Otherwise, it is estimated that this place will be melted and collapsed by the yellow spring water, and it is impossible to keep it intact!"

Shang Shanling nodded and agreed.

"Childe Cheng, what should we do with this yellow spring water?"

Shang Shanling asked, "this thing is very dangerous. It can't be collected or destroyed at all."

"This is a problem." Cheng Feng frowned.

"Cheng Feng, this Wang huangquan water comes just in time."

At this time, Nalan Changsheng interrupted, "didn't you always worry about the filth of the blue sky knife before? Now you can completely clean the filth in the blue sky knife with the help of this yellow spring water."

"Clean the dirt in the blue sky knife with yellow spring water?"

Cheng Feng was stunned: "Uncle Nalan, can this work? Yellow spring water doesn't sound like a good thing."

"Cheng Feng, although yellow spring water is vicious, it is also a kind of treasure."

Nalan Changsheng said, "many weapon refining aristocratic families spend a lot of money every year to purchase a large amount of yellow spring water from hell gate to quench weapons and purify weapon refining materials."

"If your blue sky knife is quenched with yellow spring water, it can not only remove the dirt in the knife, but also make the level of blue sky knife higher!"

"And this?"

Hearing the speech, Cheng Feng learned a lot.

It seemed that he was verifying Nalan's longevity. The black purple demon knife in Cheng Feng's hand suddenly trembled.

There was a desire from the blade to let Cheng Feng soak it in the yellow spring water.

Seeing this, Cheng Feng's eyes lit up and there was no doubt in his heart.

Then, Cheng Feng went to the muddy spring, picked up the black purple magic knife and put it into it without hesitation.

"Childe Cheng, what are you doing?" Shang Shanling didn't understand.

"It's rumored that yellow spring water can refine weapons and improve the quality of weapons. I'll try whether the rumor is true or false."

It's obviously a secret of the weapon refining aristocratic family about quenching weapons with yellow spring water.

Only after Nalan's long life, I don't know how many years of existence, can I hear about it.

As for Shang Shan Ling, naturally I don't know.

Hiss, hiss

The black purple demon knife was put into the turbid spring water. The spring water seemed to come alive and rushed to the black purple demon knife.

With the spread and immersion of the spring water, the black purple demon knife made a hissing sound.

At the same time, bubbles rose, like yellow spring water to melt the black and purple demon knife.

"Childe Cheng, is there no problem?" seeing this scene, Shang Shanling was shocked and his chest fluctuated violently.

"Nothing."

Cheng Feng was very calm, his eyes fixed on the black and purple magic knife in the spring, and a smile appeared at the corners of his mouth.

Because of his excellent eyesight, he clearly saw that under the immersion of yellow spring water, a layer of purple spots on the body surface of the black purple magic knife were slowly breaking and dissipating, revealing the shiny black body inside.

Like the blade of the black purple demon knife, it is not black purple, but pure black.

It was only because of something that the blade turned black and purple.

At this time, with the immersion of yellow spring water, the objects contaminated on the body surface of the black and purple magic knife are melted, thus revealing the body of the black and purple magic knife!

Gudu... Gudu

With the passage of time, about half a minute later, the black and purple on the body surface of the black and purple demon knife disappeared.

At this moment, it has become pure black.

It seems that he has revealed his own body, and the black purple demon knife has launched a terrible absorption of yellow spring water.

Wang huangquan water was originally three or four meters around and one meter deep, but under the crazy absorption of the black purple magic knife, the water volume decreased by one third in just a few breathing times.

"Cheng Feng, get the black knife out quickly."

At this time, Nalan's anxious voice sounded: "otherwise, the yellow spring water will be drunk by the black knife."

Hearing the speech, Cheng Feng reacted immediately.

Buzz! Cheng Feng sent out a dragon force, condensed into a dragon force claw, and grabbed the black purple demon knife out of the yellow spring water.

However, the black and purple demon knife didn't seem to drink enough. It was intended to break away from the claws of the dragon and continue to absorb the yellow spring water.

"You have drunk more than half of a pool of yellow spring water."

Cheng Feng grabbed the black purple demon knife, shook his head and said with a smile, "don't be too greedy. Leave some soup for others."

The water level of the yellow spring was indeed less than half at this time.

Cheng Feng's reaction is fast enough. If he slows down for more than ten seconds, it is estimated that all the yellow spring water is too urgent to the belly of the black purple demon knife.

After listening to Cheng Feng's words, the black purple demon knife finally stopped struggling and calmed down.

Seeing this, Cheng Feng looked up at the black purple demon knife.

It was found that the black purple demon knife had changed greatly. The blade was dark as if it had just been fished out of the ink pool, giving people an indescribable depth and massiness.

As for the little purple before that, it has disappeared.

Moreover, as the purple on the body surface of the black purple demon knife disappeared, the word "beheading the devil" appeared impressively in the position of the handle.
