(Each chapter needs to be re-read more than twice and carefully to correct typos, sick sentences, and the relationship between the top and bottom.) Very tired. Everyone's forgiveness. It's a slow effort. ）

Unloaded the Xuantie, settled on the spot, and Zhang Hao left with people. Zhou Xueyao stayed here, to be precise, she was left behind by Zhou Jue.

Zhang Hao didn't go home immediately, but went to the City Lord's Mansion. If you want to open up the road to the sea, you must unite all the forces that can be united. The strength of the country cannot be ignored, and in terms of formations, it is also ready towards.

Zhang Hao got straight to the point, directly told Liu Jingming about the plan, and finally said: "City Lord Liu, that's it." The Zhang family and the Refining Guild are ready to work together to make the Dutian Fire Array.

But to ask for living space from the sea, it is inevitable to collide with the sea monsters, so I want to borrow some formation masters from the city lord. ”

Liu Jingming's face was a little weird: "We only met yesterday, right?"

"Yes. ”

Liu Jingming seemed to smile: "Why didn't you mention it yesterday?"

"Yesterday I didn't have a mature idea, and I didn't know how to speak. ”

"Okay, how sure are you?"

"Is the city lord asking about refining weapons? or boiling the sea?"

"Both. ”

"That's 100% sure!" Zhang Hao said categorically. In other words, there is no way back, there is no other choice but to succeed.

Liu Jingming looked at Zhang Hao for a while before he said slowly: "This thing is ...... I can't call the shots, I need to report to Your Majesty!oh...... By the way, Your Majesty was also informed of the master's matter yesterday, so you can go back and wait. ”

Zhang Hao nodded, he just came to inform him, and he couldn't control what the country would arrange. The state has a form of state operation, which is different from the family and sect.

In fact, this matter, of course, wants to find a hand from the country, but it is also a statement by Zhang Hao - we have not forgotten the country, and we do not eat alone. Zhang Hao looked for Liu Jingming twice, but he was actually 'repeatedly expressing his position'. This is called having the right attitude.

Obviously, Zhang Hao's repeated statements made Liu Jingming very happy - this young man can do things.

No, Zhang Hao got up to say goodbye, and Liu Jingming personally sent Zhang Hao to the gate of the City Lord's Mansion.

When Zhang Hao left, Liu Jingming personally wrote a letter, asking people to send it to the imperial capital as soon as possible and hand it over to the emperor in person.

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

Back home, Zhang Hao went straight to the smelting base and watched everyone busy.

If you want to forge a 100,000 jin formation base, you must use the power of machinery.

In three days, Huang Mingshan and others designed a new production device. They renovated the truss of the smelting furnace, and used thick iron cast columns to support a height of more than ten meters, with thick iron cables and heavy pulley blocks above, which can lift 100,000 catties of weight.

In order to strengthen the iron cable, the lower end of the iron cable and the hook place are also reinforced with formations and seals. Since seeing Zhou Xueyao's seal usage, Zhang Hao has also learned a trick. Seals can also provide protection.

A small seal is enough to raise the high temperature resistance of the iron cable to a higher level.

The smelting furnace next to it did not stop, and the molten iron that had just been baked was directly injected into the steelmaking formation without waiting for it to cool. A furnace of molten iron is tumbling, and the smelting base is as high as a wave, even if Zhang Hao has reached the peak of the middle stage of foundation building, he is still sweating.

The fan outside the smelting base kept blowing air, which could only bring a faint coolness.

In order to increase the smelting speed, the Zhang family had to use spirit stones to strengthen the earth fire. This makes the smelting base even hotter.

The hot and blazing molten iron continued to accumulate, and the molten iron remained molten all the time within the formation barrier of steelmaking, and the molten iron was filled with a dark iron trough reinforced with formations and seals.

More than 50 tons of molten iron, quite like the ocean raging, slowly flowing in the furnace with a diameter of three meters, the slightly tumbling molten iron, reflecting the power of industry, the red-hot light, blooming the light of hope.

When another furnace of molten iron was injected, Huang Mingshan closed the notebook and shouted: "A total of 51 tons of molten iron, which is enough; ”

The so-called Reiki steaming device is the core technology of 'boiling steel'. The lower part is used to trigger the flame formation with high-grade spirit stones, and the upper part is coke refined from petroleum.

These cokes contain a thick but mixed aura, but after being 'steamed' at high temperature and high pressure, all of them become active, high-quality aura.

At high temperatures, the carbon contained in the coke will also evaporate and penetrate into the molten iron to complete the carburizing process. Although it is dark iron, it can still be strengthened by carburizing.

After the cooking device was prepared, Huang Mingshan and others checked that it was correct, and the formation was completely closed.

'Cooking Steel' is now using the 'Binding Mountain Array' from Jade Snow Mountain Resort. Compared with other formations, this formation can withstand greater pressure and higher temperature, and Huang Mingshan and others can easily master it, it can be extended to a size of ten meters, and the cutting operation is simple.

In the continuous exploration, Huang Mingshan and others found that the higher the temperature and the greater the pressure, the less aura was used, and the better the material of steel.

However, the aura can't be too small, according to estimates, each ton of steel still needs about the equivalent of one million lower-grade spirit stones.

When the formation was closed, I saw that the coke in the formation was rapidly melted and mixed with the aura released under the scorching of the flame formation. Soon the inside of the formation was hazy.

After about half an hour, the aura in the formation began to become irritable and tumbling, and the aura began to quickly turn red and red; the next moment, the aura formed a whirlpool, quickly circling and contracting; after a few minutes, all the aura was absorbed by the dark iron.

Although he has watched such a scene several times, seeing it here still amazes Zhang Hao.

Huang Mingshan and the others skillfully opened a corner of the formation to dissipate heat first, and seeing that a black floating layer began to appear on the surface of the molten iron, Yu Yueyun personally hung iron cables on the furnace. The furnace began to tilt, the sluice gates opened, and more than fifty tons of molten iron became viscous and poured into a mold buried in the ground.

The mold shape is divided into two parts. The lower part is a one-metre-diameter, eight-metre-long body, while the upper part is only 30 centimeters in diameter and has a barbed for easy lifting.

The upper part cooled down quickly, and Yu Yueyun excitedly hung the hook of the iron cable on the barb, and then began to calculate the cooling time of the lower half.

In order to speed up the cooling, in order to grab time, the lower cooling used a formation, and when the surface temperature of the steel column was reduced to about nine hundred degrees, it was determined that the steel had solidified, and Yu Yueyun ordered it to be lifted.

The bulky winch that had just been successfully tested began to operate with a clatter, the iron cables were stretched straight, and several workers were constantly oiling the pulleys and trusses. The technology is still very rough for the time being, so we can only run like this, and explore and accumulate technology.

The trusses at a height of more than ten meters creaked, and there was a screeching sound of steel rubbing between the pulleys, iron cables, and trusses. The red-hot steel pillars are inaccessible.

The orange-colored steel columns, which weigh more than 50 tons, are lifted out of the ground little by little. The barbs above the steel pillars are slightly deformed, and it seems that they cannot bear the heavy body.

"Be careful, be careful, don't shake it too much, steady, steady!" Yu Yueyun shouted, "Slow down, slow down." Get out of the way, everybody, beware of danger. ”

Zhang Hao also stood far away, and the current industrial technology was really a bit ...... A test of courage.

Lifting an object of more than fifty tons in one go, coupled with the strength of iron cables, pulleys, winches, etc., the truss almost has to bear the weight of sixty or seventy tons.

Slowly, slowly, the steel pillar finally came to the top of the pool with difficulty, and Yu Yueyun commanded the iron pillar to fall little by little.

As soon as the steel pillar approached the water's surface, a cloud of steam appeared on the surface of the water, and when the steel pillar finally entered the water, the sound of stabbing and the gurgling of water bubbles rang out, and a hazy cloud of smoke instantly spread out, submerging the entire base.

The formation worked rapidly, continuously pumping out the water vapor, but it couldn't be exhausted.
