The Green Sea of Death has rough waves, and the waves carry pebbles weighing dozens of kilograms and hit the jagged rocky beach, making bursts of thunder.
The sea water is a strange green color, and huge marine monsters can be seen on the sea from time to time.
A sea dragon with a head five to six meters long stared at Zhang Hao. The sharp horns on its head shone with cold light; its head and neck popped out of the sea like a pillar supporting the sky.
Suddenly the sea surface turned red, and a small school of fish appeared. They surrounded the sea dragon. The sea dragon was so frightened that it slithered away and disappeared.
The red fish were chasing after them, and a mouth more than twenty meters tall suddenly appeared on the sea surface. It swallowed most of the small red fish in one bite. The remaining small red fish fled in all directions.
Big Mouth was about to run away, and seaweeds emerged from the sea surface like sharp spears, and the water turned red instantly; the seaweeds shrank quickly, and the sea rolled, quickly leaving no trace; only the red blood dispersed little by little.
Zhang Hao watched silently. He had been watching here for a long time. The roaring sea breeze brought a faint salty smell.
"The Qian family must be uprooted; but more importantly, it is to gain a foothold in this world! Once the foothold is stable, the Qian family is not a problem. If the foothold is not stable, revenge is just a joke."
"Little mouse!" A friendly and loud voice interrupted Zhang Hao's thoughts. A man with a similar appearance to Zhang Shengde came flying in the breeze.
The breeze floats, and the robes are fluttering; the unruly long hair is flying in the wind, like a carefree immortal in the turbulent world.
"This is my second uncle Zhang Shengye."
Zhang Shengye is at the pinnacle of foundation building. Compared to Zhang Shengde, who is slightly more mature, Zhang Shengye looks like he is only in his twenties, handsome, handsome and extraordinary.
Zhang Shengye floated up to Zhang Hao in an elegant manner, grabbed Zhang Hao's shoulders with two strong hands, looked left and right, and laughed loudly: "Not bad, not bad, how do you feel now!"
"I worried my second uncle and everyone. He has fully recovered!
Now, I can’t wait to contribute my abilities and wisdom to the development of the family.”
"Oh, you are so sweet. Let's go, my second uncle will take you to see the smelting process of black iron."
…………
"Thousands of hammers carved out the deep mountains, and the fire burned them as if it were nothing."
The mining and smelting process of black iron is spectacular. And the entire mining and smelting base is covered by a formation barrier.
Everywhere you look you can see busy figures, about a thousand people. Although the Zhang family is not big, it is still a cultivating family.
The craftsmen were busy using sledgehammers, chisels, pries, pickaxes and other tools. The tools shone with the light of magic weapons, and the hard ore peeled off like biscuits.
The ore is crushed in a huge 'millstone', and then sent to the smelting furnace together with charcoal and low-quality crushed spiritual stones; the fire is blazing, and the molten iron is poured into iron ingots of three to four inches in size.
Zhang Shengye explained from the side: "To smelt black iron, in addition to charcoal, you also need spiritual stones.
The iron that has just come out of the furnace is crude iron, and the black iron content is less than 10%, so it needs to be forged and purified; this is also the most difficult and critical part of the black iron smelting process."
On the other side, on the forging platforms built with thick iron, there are the busy figures of blacksmiths.
They work in groups of three, one holding a fire tong in his left hand and a small hammer in his right hand, one holding a sledgehammer with both hands, and one taking care of the fire and sprinkling water on the red-hot iron with pine branches.
"This is our family's secret." Zhang Shengye's eyes flashed with pride, but then he sighed, "Now the Qian family has it too."
"The main impurity of black iron is iron. Only through repeated forging can the iron and various impurities be knocked away bit by bit.
But there is a limit. When the black iron content exceeds half, a very stubborn 'grass iron' will be formed. To continue forging and purifying, a certain method is needed.
Our method is: water forging. Water is the spiritual spring soaked with spiritual energy."
Zhang Hao watched carefully. One person sprinkled water with a pine branch, and the water droplets evenly sprinkled on the red iron block. Balls of water vapor rose up, and the sound of stabbing continued. The other two people forged, and every time the hammer fell, there were sparks flying.
, that is impurity.
The three of them took turns forging and resting. After an hour, the fist-sized piece of iron had turned into a piece of iron, and there were no more sparks flying.
The iron piece is as bright as new, with a faint precious light flowing around it, and the forged grooves are like concave mirrors, reflecting the surrounding light and shadow.
"Xuan Tie does not rust!" Such thoughts flashed through Zhang Hao's mind.
Zhang Shengye stepped forward and picked up the iron piece, and pointed his slightly shiny index finger on the iron piece. After a moment, he smiled: "The purity of black iron is 82%.
Very good! Each person will be rewarded with a low-grade spiritual stone!"
"Thank you, sir!" the three of them were overjoyed.
Zhang Hao was surprised: "Second uncle, you must be using the identification technique."
"Want to learn?"
"think!"
"Let's wait until the foundation building period. Haha..."
Zhang Hao:...Second uncle, you are naughty.
After Zhang Shengye finished laughing, Zhang Hao asked again: "Second uncle, I don't know the purity of black iron...what's the point?"
"Purity? If the purity of dark iron is above 60%, it is considered qualified and can be used to refine low-level magic weapons.
70% of them can be used to refine intermediate magic weapons.
80% can refine high-level magic weapons.
When the purity of black iron reaches over 90%, low-level magic weapons can be refined.
It is said that when the purity of black iron is close to 100%, it can be used to refine spiritual weapons."
"Now our best black iron has a purity of only 85%.
Hey...now the Qian family has also obtained the method of water forging. In the future..."
Zhang Shengye's tone was suddenly full of anger and helplessness, "From now on, we can only try our best to produce high-purity black iron to ensure the family's income!"
Zhang Hao considered it carefully and said: "Second uncle, I have an idea, maybe we can quickly obtain a large amount of high-purity black iron."
Zhang Shengye looked at Zhang Hao and asked casually: "What method?"
"Is this...the method is very simple and doesn't cost much. I wonder if my second uncle dares to try it?"
Zhang Shengye smiled: "Little mouse, you are itching to play with your second uncle by playing aggressive generals. I will ask your father."
Zhang Hao:...I thought you were going to agree~~~
Zhang Shengde came and said directly: "You can try it; but if you dare to do anything wrong, hum!"
After receiving permission, Zhang Hao shouted: Continue to heat the flowing molten iron to keep it in a molten state, 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 cloud of grey-brown, unpleasant smelling smoke rose from the surface of the molten iron.
Zhang Shengde waved his hand and released a spell, and a tornado went straight outside the barrier, taking away all the smoke.
Zhang Hao shouted: "Continue, continue, increase the air volume until no gray-brown smoke is produced. The molten iron must be stirred and pay attention to slag removal."
The craftsmen are busy.
But Zhang Hao's gaze had already shifted: a craftsman was controlling 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 was about the height of a person, and its appearance... was very "duty"!
The craftsman with a smoky face said carefully: "Master, this thing is very dangerous, please be careful."
"Why is it dangerous?"
"Explodes often."
"Explosion? Hmm...have you found the cause?"
"It's nothing, it's just that the array pattern is easy to burn, causing the spiritual energy to riot. Just... 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, spreading like water ripples, and many craftsmen around him were overturned.
It's not very powerful, but it does a somersault and lies on the ground full of gravel, powder and rust, which has a very comedic effect.
Zhang Hao stood up: "Thank you. What's your name?"
"Little man...little man Huang Mingshan." Huang Mingshan was a little excited, and the young master thanked him.
"Okay Huang Mingshan, you go about your business first and we'll talk later."
"Yes, yes!" Huang Mingshan was very excited. He quickly disassembled the fan, replaced it with a new one, and continued working.
After about an hour, there were only traces of brown smoke on the surface of the molten iron, the flame completely disappeared, and the volume of the molten iron shrank by nearly 90%.
At this time, the molten iron feels crystal clear, and there is a faint satin-like light flowing on the surface of the molten iron.
Zhang Shengde and Zhang Shengye looked excited, shocked, and dumbfounded. They looked at each other, then at Zhang Hao, and then at each other...
Zhang Hao looked at the molten iron and nodded: "Okay, cast the iron ingot and start forging."
Before the first iron ingot had completely cooled down, 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 coquettishly distributed the iron blocks to the many blacksmiths: "Continue to forge until there are no sparks flying."
"Yes!" The craftsmen rushed to grab the iron ingots, and the continuous sound of forging sounded again.
