In the evening of the next day, Zhang Hao and Zhang Shengde arrived at the family with more than a dozen carriages.

"12 sets of array flags?" Dugu Junjie, who rushed to help after hearing the news, his eyes were about to pop out, what kind of madness did the young master and the old man have, such a top-notch array flag, one set is enough. So much, what is this for?

Zhang Hao instructed Dugu Junjie: "Send them all to the smelting base." ”

After speaking, Zhang Hao went straight to the smelting base, he now has a lot of ideas to deal with, and he needs Huang Mingshan and others to help.

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

"Young Master. Huang Mingshan greeted respectfully.

"Call Bai Xiaodong and them all over. ”

After a while, a total of 32 people, including Huang Mingshan and Bai Xiaodong, all stood in front of Zhang Hao. Zhang Hao looked over one by one and nodded affirmatively: "Yes, they are all energetic and energetic, and their cultivation has made significant progress." However, it is not enough! ”

"Yes!" everyone said in unison.

Zhang Hao stood still and looked at everyone again: "Starting tonight, there is an important study. Research like this is crucial, and regardless of the results of the research, those who excel in the process will be rewarded.

Bai Xiaodong, Zhao Baishi, Wang Xuhe, Li Mingfeng, He Zhengjie, the five of you, and the team you led have worked hard these days, I have seen it in my eyes. If you perform well this time, you will join the team of Huang Mingshan and others. ”

Everyone's eyes lit up.

"Huang Mingshan, Chen Feng, Shi Donglai, Hou Shangzhuo, Liu Ming, Wang Xuefeng, Yu Yueyun, make persistent efforts. I'm sure you've seen the future!"

Huang Mingshan and others had bright eyes. Yes, they see the future, a whole new future.

"Put down your work for a moment and follow me. ”

12 formations, even with the smallest arrangement, can not be placed inside the production base. So, it's all laid out outside. In order to arrange the formation, Zhang Hao also dragged Feng Zhiling over.

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

The sky gradually brightened, and Zhang Hao stood on a small hill, looking at the rolling waves in the distance, and also at the busy crowd on the other side.

In Zhang Hao's hand, there was a small, palm-sized flying sword, circling flexibly.

After a few days of hard work, the flying sword was finally preliminarily refined. Zhang Hao silently felt the power of the flying sword.

In this small flying sword, there is an unimaginable force compressed, and the reason why the flying sword can fly is because of that majestic power.

Zhang Hao waved his hand lightly, and the flying sword staggered out and came to a boulder; the flying sword kept going, penetrating the boulder with a thickness of more than two meters like wearing tofu, and then flew back to Zhang Hao's hand in a leisurely manner.

Manipulating the flying sword made Zhang Hao's weak spiritual sense a little tired, but the power of the flying sword made Zhang Hao excited and heavy:

Recently, Zhang Hao secretly found some sulfur, saltpeter, charcoal, and some ordinary gunpowder. As a result, the gunpowder exploded in the palm of the hand, but it felt only a slight pain, a slight heat, a little blackened, and then, there was nothing.

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

Zhang Hao was still thinking about it, and Dugu Junjie flew over: "Young master, all the formations have been debugged." ”

Zhang Hao saw that the 12 formations had been arranged in a 3×4 manner, and an enchantment for shielding on the periphery was being built and was about to end.

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

By the time Zhang Hao came to the side of the formation, the blocking enchantment had already been arranged.

Dugu Junjie stopped outside the barrier. The only people who can enter the Zhang family's secret research base are the people of the Zhang family and the licensed researchers.

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

"Senior brother, the next thing is the secret of the Zhang family. ”

"I'll just see, I won't say. ”

“......”

Zhang Hao had been embarrassed to look at him, and Feng Zhiling laughed and walked out of the enchantment.

Zhang Hao turned his head to look at Huang Mingshan, Bai Xiaodong and the others, and his face gradually became serious. "What I am saying next, you must hear it clearly. If you don't understand, you can ask.

This test may be life-threatening, so everyone must understand. ”

Zhang Hao's explanation is not very clear, because Zhang Hao is just some conjectures. The current research and experimentation can be said to be unprecedented, and it requires everyone to work together.

The experiment first started with the familiar 'Trapped Dragon Array'. In addition, there are two trapped dragon formations, which can be tested and observed at the same time.

Everyone put on the strongest armor, put more than twenty black iron sticks of different purities into the formation, and then used the high-grade spirit stones and flame formations to generate flames, and millions of spirit stones were scorched on the flames.

When you finish it, quickly close the formation and wait quietly.

Within the two formations, one placed a full five million lower-grade spirit stones, and the other placed ten million lower-grade spirit stones. Coupled with the spirit stones that drive the formation, a single experiment consumes nearly 20 million lower grade spirit stones.

Next to him, the corners of Zhang Shengye's mouth twitched and he was a little excited. Twenty million lower grade spirit stones, this is a wealth that the Zhang family did not dare to imagine in the past. But now, it's just a waste......

Zhang Shengde was very calm. Anyway, now the family ...... The current family is tossed by Zhang Hao, so Zhang Shengde let Zhang Hao toss.

The temperature of the flames generated by the top-grade spirit stones was extremely high, and even through the formation enchantment, they could feel the blazing flames. The golden and purple flames licked the mountains of spirit stones above, and the spirit stones burst one after another, releasing a strong spiritual aura.

After a while, the aura inside the barrier was like a thick fog, and it was completely impossible to see the situation inside the barrier. I could only hear the sound of the spirit stone bursting, like popping beans.

Time passed, and the sun gradually climbed high into the sky. The aura within the barrier was already roaring wildly like a torrent, and it was gradually turning dark red.

Fortunately, the enchantment is really good, and it doesn't move at all. But Zhang Hao could feel the blazing heat and feel the trembling of the earth. It was as if a grumpy sun was trapped in the barrier.

Zhang Hao sighed in his heart: The world of cultivation is really magical, a formation has such an ability, and there is no need to produce any complicated equipment.

Time quietly passed for more than half an hour, and there was a sudden change in the enchantment where ten million lower grade spirit stones were placed. The aura turned from dark red to bright red, emitting a blinding light, and then the aura quickly faded as if it had collapsed.

In the surprised eyes of everyone, after only a few breaths, the aura gradually dissipated, and a whirlpool could be vaguely seen slowly disappearing, and the center of the whirlpool was the dark iron.

But at this time, the dark iron had long since melted into an irregular pool of molten iron.

Seeing this, Huang Mingshan shouted with some excitement: "Young Master, there is no pressure in the enchantment, while the molten iron has not cooled down, hurry up and cast it!"
