On the evening of the next day, Zhang Hao and Zhang Shengde together escorted more than ten carriages to the family.

"12 sets of flags?" Du Gujunjie, who heard the news and came to help, had to stare out his eyes. What madness did the young master and the old man have, so one set of top flags was enough. So much, what is this for?

Zhang Hao told Du Gu Junjie: "All sent to the smelting base."

After that, Zhang Hao went straight to the smelting base. He now has many ideas to deal with, and he needs Huang Mingshan and other help.

Huang Mingshan and others are making new improvements and designs on steam turbines, machine tools, gears, etc., and enriching the scientific system.

"Young Master." Huang Mingshan greeted respectfully.

"Call Bai Xiaodong all of them."

Soon, 32 people including Huang Mingshan and Bai Xiaodong stood in front of Zhang Hao. Zhang Hao looked at them one by one and nodded affirmatively: "Yes, they are very energetic and motivated, and they have made significant progress in cultivation. However, it is not enough! Continue to work hard."

"Yes!" The people spoke in unison.

Zhang Hao stood still and watched everyone again: "Starting tonight, there is an important study. This kind of research is very important. Regardless of the results of the research, as long as you perform well in this process, you will be rewarded.

Bai Xiaodong, Zhao Baishi, Wang Xuhe, Li Mingfeng, He Zhengjie, the five of you, as well as the team you are leading, these days I see in the eyes. If you perform well this time, you will join the team of Huang Mingshan and others. "

Everyone's eyes brightened.

"Huang Mingshan, Chen Feng, Shi Donglai, Hou Shangzhuo, Liu Ming, Wang Xuefeng, Yu Yueyun, make persistent efforts. I believe that you have seen the future!"

Huang Mingshan and others have bright eyes. Yes, they see the future, a brand new future.

"Temporarily put down my work and follow me."

Twelve arrays, even with the smallest layout, cannot be placed inside the production base. Therefore, they are all arranged outside. In order to arrange the formation, Zhang Hao also dragged Feng Zhiling over.

Huang Mingshan and others personally participated in the layout and learning; after the formation was completed, Huang Mingshan and others already had a preliminary understanding and could simply apply it; and this was enough.

As the sky gradually brightened, Zhang Hao stood on a small hill, watching the waves rolling in the distance, and the busy crowd on the other side.

In Zhang Hao's hand, a small, slap-sized flying sword hovered flexibly.

After several days of hard work, Feijian was finally refined. Zhang Hao felt the power of Feijian in silence.

In this little flying sword, the unimaginable power was compressed; the reason why the flying sword can fly is because of the majestic power.

Zhang Hao gently waved his hand, and Feijian flew out in front of a boulder; Feijian kept passing through the boulder with a thickness of more than two meters as if he were wearing tofu; then he flew around Back to Zhang Hao.

Manipulating the Flying Sword makes Zhang Hao's weak spiritual knowledge a little tired, but the powerful Flying Sword makes Zhang Hao feel heavy and excited:

Recently, Zhang Hao secretly found some sulfur, saltpetre, charcoal, and got ordinary gunpowder. As a result, the gunpowder exploded in the palm of the hand, but it only felt a little pain, a little hot, blackened a little, and then, nothing.

In other words, Zhang Hao's plan to develop gunpowder died early. The power of gunpowder is too weak for this world.

Zhang Hao was still thinking, and Du Gu Junjie flew: "Master, all the formation has been debugged."

Zhang Hao saw that the 12 formations had been arranged in a 3×4 way, and the outer enclave for shielding was under construction and was about to end soon.

Zhang Hao's heart began to heat up, "Go!"

When Zhang Hao came to the side of the formation, the shielding enchantment had been arranged.

Du Gu Junjie stopped. The only people who can enter the Zhangjia secret research base are the Zhangjia people and chartered researchers.

Zhang Hao smiled and stepped into the enchantment, and saw Feng Zhiling looking around like a curious baby.

"Brother, the Zhang family's secret is next."

"I'll just look, I won't say."

"..."

I was embarrassed by Zhang Hao, Feng Zhiling laughed and walked out of the barrier.

Zhang Hao turned his head to look at Huang Mingshan, Bai Xiaodong and others, and his face gradually became more serious. "Then what I said, you must listen clearly. If you don't understand, you can ask.

This test may be life-threatening; therefore, everyone must understand. "

Zhang Hao's explanation is not very clear, because Zhang Hao is just some conjecture. The current research and experiments can be said to be unprecedented, and everyone needs to work together.

The experiment begins with the "Sleepy Dragon Formation" that everyone is familiar with. In addition, there are two sleepy dragon arrays, which can be tested and observed at the same time.

People put on the strongest armor, put more than twenty black iron sticks of different purity into the formation, and then use the top-grade spirit stone and the flame formation method to spawn the flame, and millions of spirit stones are burnt on the flame. grilled.

When you are done, close the formation quickly and wait quietly.

Within the two formations, one placed five million inferior spirit stones; the other placed ten million inferior spirit stones. Coupled with the spirit stone that drives the formation, one experiment consumes the wealth of nearly 20 million inferior spirit stones.

Beside, Zhang Shengye's mouth twitched and excited. Twenty million lower grade spirit stones, this is the wealth that Zhang family could not imagine in the past. But now, just like that...

Zhang Shengde was calm. Anyway, now the family...can afford it! The current family is Zhang Hao toss out, so Zhang Shengde let Zhang Hao toss.

The temperature of the flame ignited by the top grade spirit stone is extremely high, even if it is bounded by the formation method, you can feel the blaze. The mixed flames of golden yellow and purple licked the mountain-shaped spirit stones above, and the spirit stones burst, releasing a strong aura.

After a while, the enchantment in the enchantment rolled like a thick fog, and the situation inside the enchantment could not be seen at all. Only the sound of the exploding spirit stone can be heard, just like bursting beans.

As time passed, the sun gradually climbed up. The aura within the enchantment has roared like a torrent, and it gradually appears dark red.

Fortunately, the enchantment was really good, and the lines didn't move. But Zhang Hao could feel the blazing high temperature and the shaking of the earth. As if inside the enchantment, a fiery sun was trapped.

Zhang Hao sighed with emotion: The world of practice is really magical; a formation has such a capability; there is no need to produce any complicated equipment.

More than half an hour passed quietly, and then the enchantment where ten million inferior spirit stones were placed suddenly changed. The aura changed from dark red to bright red, emitting a dazzling light; then, the aura quickly subsided, like a collapse.

In everyone's surprised eyes, after just a few breaths, the aura gradually dissipated, and a faint vortex could slowly be seen disappearing; the center of the vortex was the black iron.

But the black iron at this time has long melted into an irregular pool of molten iron.

Upon seeing this, Huang Mingshan shouted excitedly: "Master, there is no pressure in the enchantment. Before the molten iron has cooled down, hurry and cast it!"
