In a blink of an eye, Zhao Wude's team has been in the farm for four days.

Except for the first day, the remaining three days were quiet and no mechanical monster appeared.

During these three days, a wall built with trees and mud was successfully built, but it only surrounded the small building camp. The barn fifty meters away was lined out. After all, the construction period was short, the staff was small, and the materials were insufficient. Moreover, Zhao Wude had the words first. This was a temporary camp, just to take precautions.

It was also during these three days that Professor Hans had processed and produced 18 leader-level heavy arrows and improved three powerful crossbows, which were as powerful as the No. 3 crossbow in Tang Yizhou.

As for the eighteen heavy crossbow arrows, they were assigned to Zhao Sanxing, Lin Na, Lao Klee, Jack, Rudy, Abiao, and Zhang Yu.

The so-called knowledgeable people are heroes. Zhao Wude didn't know what method to use, so he incorporated Zhang Yu, who had a good archery skills, into the heavy crossbow team.

That's right, it can also be said to be the team's heavy firepower squad, or it can be called the first combat squad, which has the power to fight first.

Leaded by Zhao Sanxing.

This move is very beautiful. As long as this heavy crossbow team is in hand, the core of this team is there and there will be no problems with the team.

Even Tang Yizhou, a seemingly powerful crossing dragon, would not cause any storm.

So early on the fifth morning, the heavy crossbow team, led by Zhao Sanxing, went to the mountains east of the farm to search for the old nests of mechanical apes, while Zhao Wude stayed behind the camp himself, so he was safe and desirable.

With him here, Tang Yizhou is honest, let alone big guys, Roland and others.

However, Tang Yizhou has been very busy these days. After three days of skill, he finally filled up the skill of ordinary smelting. That is, today, he can try to make energy-accumulating wings.

So how could he have time to manage Zhao Wude's power management?

The barn has become his studio and base camp.

After the wall was built yesterday, due to inconvenient access, Tang Yizhou used a casual rhetoric that night and stayed in the barn.

For this reason, he also rebuilt the collapsed brick wall on the south side of the barn and moved some stones and trees to block the outside to shelter the wind and rain, which is very good.

Of course, he did not forget to bring all the spoils over. After all, his personal property is sacred and inviolable...

"Ordinary steel cannot be used to make energy-accumulating wings."

"The steel melted from ordinary mechanical wild dogs cannot be made of energy-accumulating wings."

"Even the leader-grade steel cannot be made."

"The reason is that there is a lack of a special smelting link. Through special smelting, the internal microstructure of steel is changed, well, that's about it."

At this moment, Tang Yizhou was squatting in the barn, activateing the special smelting skills with great anticipation. For this time, he saved up 150 grids of power.

He first put a piece of steel weighing about four kilograms into the prepared steel plate mold, and then activated the special smelting skill. This time, a red circle appeared at the right position of his left hand.

Lift your left hand upwards, and the red circle will shrink and press downwards, and the red circle will become larger, which is a bit of a wild pleasure of roasting ants with a magnifying glass...

Tang Yizhou tried it and found that his left hand was able to lift it upwards to fifteen centimeters. If it was higher, the skill would automatically turn off.

If you press downwards for a false pressure, it is also the limit at a position three centimeters away from the steel block. If you continue to move downwards, the skill will not be closed, but the red circle will not change, which means that as long as the left hand touches the steel block, the skill will be officially activated.

"It seems that there is no change!"

Tang Yizhou thought about it and pressed down to activate the skill, but at this moment, two options appeared in his eyes.

First, the ordinary smelting mode.

Second, the special smelting mode.

At this time, he naturally chose the second option, which is a thought. Then, changes appeared, and two more patterns appeared in his eyes.

One is the leader-level black bird, and the other is the leader-level mechanical wild dog.

This is a sign of the meaning. The former is energy-accumulating wings, while the latter is energy-absorbing steel plate.

Tang Yizhou chose the leader-level black bird without saying a word and finally confirmed.

At this point, he was surprised to find that the electricity stored in his body was withdrawn from 70 squares in this instant.

The next second, the steel block he held with his left hand melted silently and boiled, but it was no longer the red color of the past, but a silver-white color.

Tang Yizhou looked at him in amazement. It was not until the silver-white steel cooled that he hurriedly broke the mold and took it out, put it on a simple balance to measure it. It was four kilograms before, but now it has become one kilogram, and a full three kilograms are missing.

But this doesn't matter. He just wants to know how to weld it so that this thing can be turned into energy-accumulating wings?

Putting it flat on a simple workbench, Tang Yizhou tentatively activated the special welding skills. This time, in addition to the 24 red lines, a similar prompt appeared. He chose all the way, but this time, there was no one-click fool mode.

The 24 red lines of the special welding skills are combined together and become a beautiful, very spiritual arc.

Then, it was gone, there was no prompt at all.

In the end, Tang Yizhou had no choice but to take a pair of mechanical wings and weld them down like the wings. As a result, the beautiful arc fell on the silver-white steel plate, and there was no idea what chemical reaction was going on. There were silver threads jumping up, which looked very good, but also very chaotic, like carving fireworks on it...

Tang Yizhou tried four times before he could barely make the jumping silver threads tilt in one direction, so a layer of feather-like shape came out.

At this moment, he jumped up with excitement.

I see!

Next, he quickly learned his lesson, started from one end of the silver-white steel plate, and controlled the arc to weld out silver wires one by one, forming feather-like shapes that looked like feathers, but were actually ugly.

Fortunately, special smelting consumes electricity, but special welding saves a lot. Only by welding a feather can one piece of electricity be consumed.

Finally, except for the four places on this steel plate, the other areas were successfully welded. Including the front and back sides, there are 36 feathers in total.

"I don't know what the effect looks like, but this item is not included in the equipment list in the attribute bar, which means it is quite bad."

Tang Yizhou thought to himself, but he was not discouraged. As for his experience, he only accumulated a little bit.

However, when he put the silver feather steel plate in the sun, he was shocked to find that the thing had changed color, no, it was burning, and a layer of golden flame jumped on it...

No, it's not the flame, it's the silver transparent silk threads flying up, absorbing a lot of sunlight in a short time, so it looks like flames.

In addition, it can be seen from here that in some places the thread is not good enough, the sunlight absorbs less, and even does not respond at all, and in some places there are many.

The whole process lasted for about one minute, and the silver transparent silk threads fell down, solidified and turned black. When I looked at it, it was already 80% similar to ordinary mechanical wings.
