In the early morning, the golden sunlight awakens the sleeping earth. Inside the Zhang family, it didn't stop overnight.

Zhang Hao stood next to him, looking at the sonorous and busy crowd, and felt an unprecedented shock.

In front of the 8.6-meter-high steel column, people are so small. However, in one night, the small man changed the appearance of the steel column.

On Lu Yang's side, more than half of the steel pillars have been carved into the seal, and the upper part of the steel pillar is still black, but the lower part has been cleaned and polished, and the blue light and the golden sunlight reflect each other.

And Zhang Xinhan's side is a different face. The seal carving method they adopted was from the point to the surface - first draw it down to make sure that there was no problem, and then engrave some important nodes, and then carve the main formation patterns between these nodes.

In one night, Zhang Xinhan just carved the main formation patterns, but the steel column has not been polished and cleaned, and the steel column as a whole is still black.

In the golden sunlight, this steel pillar shimmered with bright lines. These lines, like the sunlight in the dark clouds, are particularly eye-catching. The whole steel column is calm and heavy, showing a mysterious brilliance.

But Lu Yang, Zhang Xinhan and others don't have the mood and time to appreciate their works, they are working overtime.

Judging from the current situation, Zhang Xinhan's progress is obviously lagging behind Lu Yang's.

Many people have begun to cheer for Lu Yang. But Zhang Hao's eyes were focused on Zhang Xinhan's side.

Zhang Hao appreciates Zhang Xinhan's way of doing things more, and only in this way is a truly reasonable way of doing things, and it is also a way of doing things with the spirit of scientific research.

Unconsciously it was sunset again, and Lu Yang finally completed the portrayal of the main body of the steel column. He looked at the 0.6-meter-high barb above, and thought about it, and also carved the formation on it. But what he carved is obviously not the 'Trapped Immortal Array'.

"It's the Demon Refining Array!" Zhou Xueyao spoke, she stood next to Zhou Jue and Zhang Hao, and explained softly, "The Demon Refining Array, in fact, can be regarded as a special alchemy array, this is a formation handed down from ancient times, but the formation is mostly incomplete, and the current Demon Refining Array is after we repaired it."

At present, the Demon Refining Array can directly refine the essence in the demon beast's body and store it in the acupuncture points in the demon beast's body.

But it can't be done as in the legend, directly refining the demon beast into an elixir.

We also need to take out the essence of the demon beast and use the alchemy furnace to refine the pill. ”

Zhang Hao nodded silently, but he understood in his heart that this so-called demon refining array could also refine people.

However, Zhang Hao keenly noticed that when Zhou Xueyao said 'refining demons', her expression was very flat, as if she was saying: Let's eat chicken or pork for dinner.

For cultivators, demon beasts have always been the target of hunting. It's just that the sea monsters are relatively powerful, and the deep sea is not easy to use, so it is safe for the time being.

In fact, the reason why the 'inland sea' between several continents, such as the Emerald Sea, is safe is that almost all of the monsters in it have been hunted by humans.

Zhang Hao looked at it for a while, and then left, there are still a lot of things waiting for Zhang Hao to deal with. For example, Hou Shangzhuo and Wang Dake finally took all the craftsmen to make the first model, a ship model made of 'rough iron', and it has been successful.

Zhang Hao received the message and left. In the smelting base, a new 'research team' is busy.

When Zhang Hao arrived, Hou Shangzhuo and Wang Dake were standing excitedly by the pool, and in a pool of about ten meters next to it, a one-meter-sized model of a ship made entirely of ordinary rough iron was slowly advancing.

The ship was not large, and the structure was rudimentary, with only one hull. However, it is this small model, but it is a qualitative leap.

First of all, there is the material, this is a ship made of iron, and it floats on the water, without any formation assistance. This may be common to Zhang Hao, but for people in this world, this is a new beginning.

The moment the ship made of rough iron could float, a whole new world slowly opened up in front of them.

Everyone's eyes were still flashing with surprise.

The second is the power system, which uses a small impeller directly driven by spirit stones, and the impeller drives the propeller. Not a lot of power, but it's really mechanical.

This means that the ship will completely get rid of the traditional methods such as sails and oars, and compared to the ship driven by spirit stones, formations, spells, etc., it will have more power, longer durability, and lower energy consumption.

There is also the shape of the ship, Zhang Hao was surprised.

Previously, Zhang Hao only mentioned one point, saying that the sea waves were too big and the draft should be increased to ensure the stability of the ship, but Hou Shangzhuo, Wang Dake and others directly studied the sunken cabin shape.

To put it simply, the principle of a sea boat and an ordinary river boat is completely different.

Ordinary boats, that is, flat-bottomed boats, float on the water, and the 'center of gravity' of the boat is also on the water. In this way, it will naturally lead to instability and turbulence of the ship.

But sea ships are not, and the center of gravity of sea ships is below the surface of the water. Somewhat similar to the principle of a tumbler.

No, Hou Shangzhuo excitedly showed Zhang Hao the 'principle'. One is rolled into a cone of impermeable, oil-soaked paper, and an iron block is placed underneath the cone.

Then gently place the cone in the water.

The cone sinks about a third of the way to the surface of the water, and two-thirds floats above the water; No matter how Hou Shangzhuo stirred the water, the cone floated steadily on the water, and the bumps were not big.

Hou Shangzhuo and the others shouted excitedly, otherwise it was not enough to vent the surprise, surprise, and shock in their hearts.

Zhang Hao smiled faintly. Of course, Zhang Hao understood this truth, but seeing that Hou Shangzhuo and others began to study this truth from nothing, Zhang Hao was very satisfied.

They have already begun to delve into physics deeply. Scientific ideas and ways of thinking have taken root in their hearts.

Zhang Hao clapped his hands, and immediately guards came in, these guards were holding plates in their hands, and on the plate were bottles of Pei Yuan Dan.

"Everyone, Hou Shangzhuo and Wang Dake will reward Pei Yuan Dan with 10 and 5 high-grade spirit stones......"

Zhang Hao personally watched all the rewards be distributed, and there were more than 300 people on the scene, and none of them were left behind. Of course, some of them do not contribute, so they will only reward an ordinary low-grade spirit stone, in fact, one is a subtle warning: Be careful, there are no idlers here!

Rewards, the most motivating. Before leaving, Zhang Hao said that the next step was to build a ten-meter-sized model. As a result, Hou Shangzhuo and Wang Dake patted their chests and promised that even if they didn't rest, they would definitely do it within ten days!

Ten days? Zhang Hao smiled, he wanted to say a month.

Ten days was actually very tense, but considering that everyone had cultivation in their bodies, and they knew more or less a little magic, Zhang Hao nodded. Let's take a look in ten days, but Zhang Hao feels that in ten days, Hou Shangzhuo and they may not even be able to finish the keel.

The time inadvertently came to the morning of the third day. When Zhang Hao came to the courtyard again, Lu Yang had already completed the seal carving and was baking the fine gold with the 'flame', and the pure gold was gradually integrated into the formation.

Its flame was a gorgeous purple color, and Zhang Hao could faintly feel the temperature of the flame from a distance of more than ten meters.

Under the calcination of this flame, the pure gold turned into golden flowing water to the formation pattern, and gradually seeped into it.

Because of the flowing properties of melted pure gold, Lu Yang was "gilded" from top to bottom. At this time, most of it was completed, and a faint golden light appeared in the gilded array, echoing the faint blue light of the dark iron itself, exuding a beautiful and mysterious brilliance.

Then he turned his head to look at Zhang Xinhan next to him, he had just finished carving the seal of the formation and was inspecting. Compared with Lu Yang's formation, Zhang Xinhan's formation presents a 'sense of regularity and layering'. The main pattern is thicker, while the secondary pattern is thinner and well-layered.

In particular, the upper part of the barb was carved into the shape of a dragon's head. Although it is slightly abstract, the unique charm of the dragon has seven points.

Zhang Xinhan checked very carefully, and made sure that there was no problem, so he asked people to prepare the pure gold, and he sat cross-legged in the void, and a flame as red as coral gradually appeared on his hands, and the flame faintly showed the phantom of a lotus flower.

The pure gold rolled into red as soon as it rolled through this flame, and then it rolled into golden flowing gold, and he likewise 'gilded' from top to bottom.

Pure gold begins with the dragon's head, and the gold-plated dragon's head is more majestic, and the nobility of the dragon leaps into being. The dragon head under the light of the morning sun seems to be alive!

"Okay!" Seeing this, Zhang Hao couldn't help but admire.

Then Zhang Hao asked Zhou Jue who came over next to him: "Brother Zhou, the flame in the hands of Lu Yang and Zhang Xinhan is a different fire?"
