The green sea of death was turbulent, and the waves rolled dozens of catties of pebbles and smashed on the jagged rocky beach, sending out bursts of thunder.

The sea is a strange dark green color, and huge sea monsters can be seen from time to time on the sea.

A sea Jiao with a head of five or six meters big stared at Zhang Hao, the sharp corners above his head shining with cold light, and the head and neck that popped out of the sea were like a pillar of optimus.

Suddenly, the sea turned red, and a small school of fish appeared, and they surrounded the sea Jiao. The sea Jiao was so frightened that it disappeared after a moment's notice.

The red fish pursued, and a mouth of more than 20 meters suddenly appeared on the sea, swallowing most of the small red fish in one bite. The remaining little red fish scattered and fled.

The big mouth was about to run away, and the seaweed burst out of the sea like sharp spears, and the sea water turned red in an instant; the seaweed shrank rapidly, and the sea rolled over, and soon there was no trace; only the red blood scattered little by little.

Zhang Hao watched silently, he had been watching here for a long time. The howling sea breeze brings a faint salty smell.

"The Qian family must be pulled out, but what is more important is to gain a foothold in this world! Once the foothold is firm, the Qian family is not a problem. The foothold is unstable, and revenge is just a joke. ”

"Little mouse!" A kind and loud voice interrupted Zhang Hao's thoughts, and a person with a similar appearance to Zhang Shengde flew in the breeze.

The breeze floats, the clothes flutter, and the unruly long hair flutters in the wind, like a carefree immortal in the turbid world.

"It's the second uncle Zhang Shengye. ”

Zhang Shengye, the cultivation of the pinnacle of the foundation. Compared with Zhang Shengde, who is slightly old, Zhang Shengye looks only in his twenties, handsome and extraordinary.

Zhang Shengye floated in front of Zhang Hao in a dashing manner, grabbed Zhang Hao's shoulders with two strong hands, looked left and right, and laughed loudly: "Not bad, how do you feel now!"

"Let the second uncle and everyone worry. It's been fully recovered!

Now, I can't wait to contribute my ability and wisdom to the development of the family. ”

"Yo, my mouth is sweet. Let's go, the second uncle will take you to see the smelting process of Xuantie. ”

............

"Thousands of hammers are carved out of the mountains, and the fire burns as if it were idle. ”

The mining and smelting process of dark iron is spectacular. And the entire mining and smelting base is covered by the formation enchantment.

As far as the eye can see, there are busy figures, about 1,000 people. Although the Zhang family is not big, it is also a family of cultivators.

Craftsmen are busy with tools such as sledgehammers, chisels, pries, and pickaxes, which shimmer with the light of magic tools and peel off the hard ore like biscuits.

The ore is crushed in huge 'millstones', and then sent to the smelting furnace along with charcoal and inferior crushed spirit stones, and the molten iron is poured into pieces of iron ingots of three or four inches in size.

Zhang Shengye explained beside him: "To smelt dark iron, in addition to charcoal, you also need spirit stones.

Crude iron is just baked, and the content of dark iron is less than 10%, which needs to be forged and purified, which is also the most difficult and critical in the process of black iron smelting. ”

On the other side, on the forging platforms made of rough iron, there are busy figures of blacksmiths.

In groups of three, one holds a tongs in his left hand, a hammer in his right hand, and a sledgehammer in both hands, and one takes care of the fire and sprinkles water on the red-hot iron with pine branches.

"That's our family secret. Zhang Shengye's eyes flashed with pride, but then he sighed, "Now the Qian family has also gotten it." ”

"The main impurity of the dark iron is iron, and only through repeated forging will the iron and various impurities be knocked out little by little.

But there is a limit to this, and when the amount of dark iron exceeds half, a very stubborn 'grass iron' is formed. To continue forging and purifying, a certain method is required.

Our method is just that: water forging. Water is a spiritual spring that infiltrates the aura. ”

Zhang Hao watched carefully, and a person sprinkled water with pine branches, and the water droplets were evenly sprinkled on the red iron, and a cloud of water vapor rose, and the sound of stabbing was endless. The other two forged, and every time the hammer fell, there was a spark splash, which was impurity.

The three of them took turns forging and resting, and after an hour, the fist-sized piece of iron had turned into a piece of iron, and there was no longer any spark splashing.

The iron sheet is as bright as new, faintly flowing with treasure light, and the forged grooves are like concave mirrors, reflecting the light and shadow around them.

"Xuantie, it's not rusty!" Zhang Hao's thought flashed in his heart.

Zhang Shengye stepped forward to pick up the iron sheet, and pointed his slightly shiny index finger on the iron sheet. After a moment, he smiled: "The purity of the dark iron is 82%.

Very good! Each person will be rewarded with a spirit stone!"

"Thank you, Chief!" the three of them were overjoyed.

Zhang Hao was surprised: "Second uncle, what you use is identification." ”

"Want to learn?"

"Yes!"

"Let's wait until the foundation building period. Haha......"

Zhang Hao: ...... Second uncle, you are naughty.

When Zhang Shengye finished laughing, Zhang Hao asked again: "Second uncle, I don't know the purity of Xuantie...... What's the point?"

"Purity, the purity of Xuantie is above 60%, even if it is qualified, it can be used to refine low-grade magic weapons.

70% of them can refine intermediate magic weapons.

80% of them can refine high-level magic weapons.

When the purity of the dark iron reaches more than 90%, you can refine the low-grade magic weapon.

It is said that when the purity of the black iron is close to 100%, it can be used to refine spiritual weapons. ”

"Right now, our best black iron is only 85% pure.

Ay...... Now the Qian family has also obtained the method of water forging. ...... later"

Zhang Shengye's tone was suddenly full of anger and helplessness, "In the future, we can only try to produce high-purity dark iron to ensure the family's income!"

Zhang Hao pondered and said, "Second uncle, I have an idea, maybe I can quickly get a large amount of high-purity dark iron. ”

Zhang Shengye looked at Zhang Hao and asked casually, "What method?"

"Is this ...... The method is very simple, and the cost is not large, I don't know if the second uncle dares to try it?"

Zhang Shengye smiled: "Little mouse, playing with the second uncle is itchy." I'm going to ask your father. ”

Zhang Hao: ...... I thought you were going to say yes~~~

Zhang Shengde came and said directly: "You can try, but if you dare to come, hum!"

With permission, Zhang Hao shouted: the molten iron that flowed out continued to heat and keep it melting, add an appropriate amount of crushed spirit stones, and then inject a large amount of air.

A dark red flame burned on the surface of the molten iron, and a puff of gray-brown, choking and dry foul-smelling smoke rose from the surface of the molten iron.

Zhang Shengde waved his hand and released a spell, and a tornado went straight to the outside of the barrier, taking all the smoke with it.

Zhang Hao shouted: "Go on, go on, increase the amount of air until there is no gray-brown smoke." The molten iron should be stirred, and attention should be paid to slag discharge. ”

The craftsmen are busy.

But Zhang Hao's gaze has shifted: a craftsman is operating a clumsy fan to blow air into the molten iron.

Zhang Hao turned around, and finally squatted next to the fan to observe. The fan is about the height of one person, and the appearance is ...... Very "duty"!

The craftsman with a face full of fireworks said cautiously: "Young master, this thing is very dangerous, you be careful." ”

"How dangerous?"

"Frequent explosions. ”

"Explosion? huh...... Did you find the reason?"

"It's nothing, it's just that the formation pattern is easy to burn, causing the aura to riot. As long as...... Be careful!"

The craftsman suddenly hugged Zhang Hao and squatted down, the fan next to him made a muffled sound, and a wave of spiritual energy rushed out and spread like water ripples, and many craftsmen around were overturned.

It's not very powerful, but it's a comedic flip and lying on a ground full of gravel, powder, and rust.

Zhang Hao got up: "Thank you." What's your name?"

"Villain...... Villain Huang Mingshan. Huang Mingshan was a little excited, and the young master thanked himself.

"Okay Huang Mingshan, you get busy first, and we'll talk about it later. ”

"Yes, yes!" Huang Mingshan excited. Mali dismantled the fan, replaced it with a new pattern, and continued to work.

After about an hour, there were only wisps of brown smoke on the surface of the molten iron, the flames disappeared completely, and the volume of the molten iron was reduced by nearly ninety percent.

At this time, the molten iron has a sense of crystalline, and there is a faint satin-like treasure light flowing on the surface of the molten iron.

Zhang Shengde and Zhang Shengye looked excited, shocked, and stunned, and the two looked at each other, then at Zhang Hao, and then at each other......

Zhang Hao looked at the molten iron and nodded: "It's okay, cast the iron ingots and start forging." ”

Before the first iron ingot had completely cooled, Zhang Shengde grabbed it, threw out the identification technique, and was dumbfounded: "Pure ...... Purity...... 93%......”

"Hiss......" Zhang Shengye and many craftsmen around him gasped.

Young Master Zhang Hao was very calm, and distributed the iron to many blacksmiths: "Continue to forge until there is no spark splashing." ”

"Yes!" the craftsmen scrambled to grab the ingots, and the sound of continuous forging sounded again.
