"What?" asked the dragon.

"If you want to get rid of the violent anger of the black water, you have to get rid of the impurities inside!" said Zhi Butong.

"To remove impurities, you need to use a special way. I have tried drying in the sun and drying in the wind, but no matter how long the operation takes, it cannot remove the impurities in the black water. ”

"Oh, have you used the sedimentation method?" Cuicui thought of a solution.

"Put sand in the black water, let the sand fully absorb the violent qi in the black water!"

"How is this possible!" Zhi Butong shook his head, "If that's the case, how can the black water in the deep mountain ravine be decades or even hundreds of years old, and still be violent?"

"That's right!"

"Why don't you use the fire roasting method?"

"Fire roasting?" Zhi Butong frowned, "I tried before, and it either burned or exploded!"

"No open flames!" said the dragon, shaking his head.

"What kind of fire can you use without an open flame?"

"True fire, yin and yang real fire!"

"Yin and Yang True Fire, but the person who manipulates this true fire must be a person of great virtue, at least a powerful person in the Great God Realm, and the people in the Great God Realm were extinct a hundred years ago, where can we find other capable people in the Great God Realm in today's world?"

"In addition, even if they can find it, they may not be able to leave the mountain because of this little thing." What's more, the great god we are looking for must be a fire-attribute person......"

Zhitong muttered to himself while going back and forth.

As everyone knows, the imperial dragon and Cuicui beside him laughed.

The emperor dragon stretched out his hand, the palm was facing upward, and the internal strength was running, and with a "whew", a cluster of fire burned in the palm of the emperor dragon's hand.

"This ...... What kind of fire is this? It's on fire!!" Frightened, he hurriedly hid behind Cuicui.

"Haha!"

Huanglong and Cui'er laughed happily when they saw the funny appearance of the incomprehensible.

"No, don't be afraid! What Yao Gongzi is using is true fire, and it is a rare fire attribute thunder in the world!"

"Fire attribute thunder qi? I didn't expect that Gongzi would be able to master the world's extraordinary martial arts at a young age, which is simply admirable and admirable!"

The emperor was busy returning the salute.

"Great! With Yao Gongzi here, everything is ready and only the east wind is owed! In this case, why don't Yao Gongzi try it?"

"That's right, big brother, try it! Idle is idle?" Zhang Tieniu also made a noise.

"Good!"

As soon as the imperial dragon threw out Mount Tai Fuding, it was cheered by everyone and applauded this strange young man.

Cui'er on the side cast an envious gaze at the imperial dragon. There was adoration in his eyes.

The imperial dragon exerted its internal strength to give birth to the fire of internal strength and heat up Fuding.

At this time, Zhi Butong held a stone bowl, the stone bowl was full of black water, and the water surface was blooming with colorful patterns.

The imperial dragon used its internal strength to raise the stone bowl and slowly floated into the Fuding.

As soon as the stone bowl reached the top of Fuding, it exploded.

"Bang!"

The air mass directly extinguished the real fire.

The imperial dragon looked at this scene and frowned.

"Come again!"

Repeat.

I tried a few more times and it still worked.

The dragon gasped for breath, beads of sweat oozing from his forehead.

At this time, Fuding has been covered with black water and turned into a black Taishan ink jade tripod.

"What's wrong?" the dragon pondered.

At this time, Zhi Butong sighed, "Hey, it's a pity! I thought that I could remove impurities through real fire, but I didn't expect it to be impossible, it seems that this black water is useless!"

"Sir, why do you insist on removing impurities from the black water?" asked Cui'er, puzzled. This sentence also spoke in the eyes of Huang Long's heart, and he was also about to ask this sentence.

"Since ancient times, we human beings have used wood to make fire, and wood or pine oil as candles, these lights are weak, and produce a lot of smoke, and a little carelessness is easy to cause fires, resulting in the death of people and property. If black water can be used by us, it has many advantages, first of all, the brightness is there, it shines like day, it has no smoke, and its heat is particularly strong, the heat of a drop of black water is exactly the heat of a ton of firewood, and it is very easy to forge bronze smelting furnace water. ”

Huang Long's eyes lit up when he heard the words of Zhi Butong.

He thought to himself: "Isn't this just the relief of the pain in my heart? I have been troubled for a long time by the true fire that cannot reach the fire of the realm, and I can't imagine that God will live up to his heart, and I am still troubled by being trapped here and unable to get out, but I didn't expect that Grandma Taishan actually pointed out a strange path for me, so that I could find a way to solve the lack of heat." ”

"According to Big Brother Zhibutong, I only need to remove the impurities in the black water, and I can increase the heat of refining the pill by carrying the black water in the future, so that the incineration and tempering of the mandala flower will become very easy!"

Thinking of this, Huanglong snickered with joy.

"But, big brother who can't understand it, I've tried it repeatedly, and the manic energy in the black water is too strong to remove the impurities in it! How can we tame the black water and make it our use?" asked the emperor dragon wiping his sweat.

"In this way, one more item has been eliminated!" Zhi Butong said, and took out a thick notebook from his bosom, opened it, and drew on it.

"What is this?" asked Cui'er, leaning closer.

"Of the various ways I've experimented with removing impurities, there are only two left, and the real fire doesn't work either. There is only one method left, and if this method doesn't work, it will be completely hopeless!" Zhi Butong looked at the black water in front of him and sighed.

At this time, the deep pit that Zhifu was sinking into was already full of black water, and it had turned into a huge black water pool.

"So, what's the rest of the way?" asked Cui'er curiously.

"Gu Poison Water!"

"Gu poison water?" several people exclaimed in unison.

"Make no mistake! That's what the big devil specializes in harming people! So many young and strong laborers in our village were captured by that witch, and it was only by pouring this poisonous water that they became zombies of the walking dead! If it weren't for this thing, I'm afraid those people in our village wouldn't have ended up so miserable!"

Zhang Tieniu clenched his fists and gritted his teeth.

"Brother Tie Niu, I know this is a cruel fact, but have you ever thought that a water-like thing that turns people into zombies after being forced to take it, must have drained people's blood and even flesh?"

"If you inject it into this black water, it will definitely drain the water in it and remove the impurities of the black water. Because it was originally cruelly used on people by the wicked, I put it on the last item of hundreds of methods. ”

"However, I think this formula must have been developed by a master, and it was simply used to remove impurities in the liquid of herbs, but it was taken by the gangsters and used on people. ”

"I'm afraid Brother Tong is right! Alchemists have developed too many mysterious formulas and achieved many myths, some of which have been used in crops, some in vegetables, and some in medicine. "Huanglong firmly believes that if there are no alchemists in the world, the world will definitely be stagnant, at least in many fields, there are many new inventions missing.

"I think so!" Zhang Tieniu patted his big belly and said with a big grin, "When I planted vegetables, I sprinkled a potion on them, and all the insects died, so the vegetables I Tieniu planted were big and bright, and the price was higher than theirs." Later, I heard that the potion was asked for by an alchemist. Butler, do you say?"
