At noon, the rain was less, but the fog became stronger, especially in the valley, where the milky white fog was rolling happily like huge marshmallows.

Tang Yizhou, who had changed into dry clothes, sat on the trolley and studied the two drawings of mechanical creation with a ray of light.

First of all, his drawings for strengthening magnetic blade grenades. The manufacturing principle is the same, but it is even more powerful. It has 300 blades, which can rotate at a speed of 300 kilometers per hour in a region of five meters high and twenty-seven square meters under the action of an electromagnetic force field.

It is estimated that they can severely damage the leader-level mechanical monster.

But the price is also very cruel. A golden energy ball can only be magnetized twice.

So after studying for a while, Tang Yizhou finally decided to postpone the production.

The golden energy ball in his hand is not as generous as possible to consume like this. Isn’t it nice to use it to make a mechanical crow for reconnaissance?

And he now just met the conditions for making a mechanical crow, namely, a golden energy ball, five blue industrial balls, and at least three red detection balls.

"The enhanced version of the magnetic blade grenade is temporarily suspended. Four ordinary magnetic blade grenades can be made first, and the mechanical crow can also be put on the production schedule. In addition, the No. 4 crossbow, energy-accumulating wings, energy-absorbing light steel, and this mini crossbow arrow launcher, all of which need to be built in the near future."

"In short, it is not possible to develop without ten days and half a month. If the influence of abnormal weather is removed, the time will be longer. Therefore, you have to calm down and patiently. Those who do not develop will not live."

Tang Yizhou sighed in his heart, and then he drove away distracting thoughts and continued to study the drawings of the micro crossbow arrow launcher.

The structure of this mechanical creation is a bit complicated.

Of course, this is for him.

In fact, it should be very simple. These mechanical creatures have a big feature, that is, they use golden energy balls to solve the most core technical difficulties and solve the core of power.

For example, Tang Yizhou's magnetic blade grenade, he cut 100 standard blades, and the rest were magnetized directly with a golden energy ball.

The same is true for this micro crossbow launcher now. Its core device is a permanent reversible variable magnetization device, which can directly connect with the golden energy ball, create magnetization in a small range, and form a reverse electromagnetic force field.

Well, the electromagnetic force field formed by the magnetic blade grenade is compressed inward, which is to explode outward, and then push the crossbow arrow to launch.

That's the principle.

This reversible magnetization device, from the drawings, is like a cylinder, and requires a spring device to clamp all crossbows on it. When the electromagnetic force field is turned on, it will convert the electromagnetic force field and quickly eject the crossbows.

So the finished product will not be square, but rather like a mortar...

I imagined the scene of Zhang Xin carrying a mortar in the future. Not to mention the power, it was really funny.

It took Tang Yizhou half an afternoon to study the drawing thoroughly, draw various three views, calculate the size data, and cut the mold samples with wood.

If he hadn't been worried that the rain would last for several days, he could have started to build it now.

As for the drawing of the mechanical crow, he even drew three views a few days ago. In a word, what he lacked is time, electricity, and golden energy balls.

Now, he still needs to activate a wave of skills in the industrial sector and detect the skills in the sector.

Open the mechanical properties bar and the information on it will be clear at a glance.

Current holder: Tang Yizhou

Current permissions: The third layer, when you open the next layer of permission, you need to obtain a total of 10/10 gold energy balls, 150/150 blue industrial balls, 50/50 red detection balls, and 1/1 white technology balls.

Golden energy balls: 2 (4 remaining magnetization times), and 3 are accumulated.

Blue industrial balls: 33, 40 were obtained in total.

Red detection balls: 12, a total of 12 were obtained.

Remaining power: 50/615 grids

Passive skills: Level 2 energy storage, skill description, standing in the sun, can continuously recharge the charge, 2 grids/hour.

Active skill (left hand): Level 5 main skill tree (welding).

Active skill (right hand): Level 2 main skill tree (cut).

Branch Skill 1: Ordinary Welding (500/500) Note: This is the basic skill that comes with your left hand.

Branch Skill 2: Normal Smelting (500/500)

Branch Skill 3: Normal Cutting (500/500) Note: This is the basic skill that comes with your right hand

Branch Skill 4: Strengthen Cutting (500/500)

Branch Skill 5: Special Welding (120/1000)

Branch Skill 6: Special Smelting (90/1000)

Branch Skill 7: Ordinary Hunting Memory (no proficiency required, hunting Memory can be loaded infinitely, current memory × 3)

Binding equipment: Mechanical tower shield (standby)

——

After checking this attribute column for a moment, Tang Yizhou thought about it and assigned two blue industrial balls to the right-hand cutting trunk skill tree, instantly upgraded it to the third level trunk, and obtained a new branch skill.

Ordinary polishing (right hand): It can polish the surface of the object with higher precision (0/500).

"It's not easy, I finally have a polishing skill."

Tang Yizhou grinned. With this skill, in the future, whether it is to make magnetic blade grenades, or make leader-level heavy arrows, light arrows, even number four crossbows, armor, or miniature crossbow arrow launchers, they can all speed up and increase quality.

It can be said that the skills are inconspicuous, but they are of great effect.

Next he allocated four blue industrial balls to his right hand, upgraded his level to a level four main skill tree, and obtained a new branch skill.

Ordinary drilling (right hand): The object can be drilled with a minimum diameter of one centimeter, a maximum diameter of five centimeters, and a maximum depth of 10 centimeters. (0/500)

It is still an ordinary skill, but it is also irreplaceable. Tang Yizhou can even make a flintlock rifle through this skill, although he actually doesn't know how to do it, although it's useless...

However, if he obtains higher-level mechanical drawings in the future, he will definitely be able to use them. Even this drilling skill can be used on the micro crossbow launcher, which can reduce the complexity of the process by half and the power consumption will naturally be greatly reduced.

"Sure enough, if a mechanic warrior doesn't have mechanical skills, it's better to hang a southeast branch by himself."

At this time, Tang Yizhou still had 27 blue industrial balls in his hand. After deducting the five mechanical crows, the five that need to be kept for daily strengthening, there are still 17 left.

At this time, he hesitated for a moment, and then gave up the sixth branch skill to light up the left hand. This skill requires 16 blue industrial balls, which must be very powerful and sharp, but now he also saw that the skills of the industrial sector are not about how powerful it is, but how comprehensive it is.

Welding with left hand and cutting with right hand, none of them can be missed.

At this moment, Tang Yizhou decisively allocated eight blue industrial balls, illuminating the fifth branch skill of the left hand.
Chapter completed!
