……

"Now I have a total of twenty skill books, which are...... One passive type, five industrial types, and nineteen research types, the most of which are research type skill books, I really don't know what this research type is......"

Looking at the page listed by Alice, Mu Feng secretly calculated the skills he needed in his heart, since there is only one passive type, it must be very good! With the urine nature of the previous system, the things that can be drawn the most in the lottery are not good things.

In other words, these nineteen skill books are useless, at least they are useless to Mu Feng, the only thing that makes him more satisfied is the five industrial types and the passive type of skill books, in terms of quantity, the passive type should be the strongest.

As for the nineteen research books, Mu Feng didn't want to move at all, because he just wanted to improve his strength, and he didn't want to do any research and development, these nineteen skill books could be left for others to use, anyway, Mu Feng didn't plan to use them himself.

Skill book for industrial type...... It should be researching vehicles and the like, which is still very useful for Mu Feng, because he can find some accessories that can be added to the mecha from this, and he can also change the mecha according to the characteristics of the vehicle.

Mu Feng; "Then I'd better open the industrial type of skill book first, as for the passive one, just wait and read it again, it's not bad to surprise yourself, and the last nineteen skill books will be left alone, and then given to others when they have the opportunity."

Just do it, Mu Feng directly took out five industrial-type skill books, these skill books look very similar to ancient Chinese classics, they are all blue on the outside and yellow on the inside, and they are all wire-bound versions, which are almost exactly the same as the martial arts cheats on TV.

"Smack!"

Mu Feng casually picked up a book and gently knocked on the door of his head, and suddenly a blue light emitted from the skill book, and the blue light suddenly drilled into Mu Feng's mind, and then the skill book disappeared, as if it had never appeared.

The production method of the N92 aircraft (low-level); An unknown vehicle from a mysterious planet, similar to a backpack, with wings extending from both sides of the backpack and jets underneath the backpack for short flights.

For this skill, Mu Feng's heart was only speechless, he didn't want this thing, because Mu Feng has the ability to levitate, and he doesn't have to worry about not being able to fly in the future, this thing is similar to chicken ribs for him, and it is just useful to others.

"I'm unlucky now, if this one skill is a skill, I'll just draw the drawings of the aircraft directly, then I'll delete this skill!" Mu Feng smiled helplessly.

"Smack!"

Immediately after, Mu Feng opened the second skill book.

It's still the same as just now, when this skill book touched Mu Feng's forehead, it suddenly emitted a blue light, and then it quickly disappeared, and a lot of information suddenly poured into Mu Feng's mind, the kind that couldn't be stopped.

A5 Fifth Fighter Fabrication Method (Low Rank); Fighter jets have always been the best in war, and they can be used for air raid bombing, especially this fighter is more powerful, even more powerful than fighters of the same level, please be careful when using it!

This skill...... It's more reliable than the one just now!

Because the vehicle made by this skill has one more attack ability than the previous aircraft, and it is no longer a "meat wrapped in iron", and it may be shot down by someone when using a flying machine, but it is much safer if you use a fighter.

Mu Feng suddenly opened his eyebrows and smiled, and said; "This skill is good, stay and learn it first!"

After memorizing the production method on this one skill book, Mu Feng looked at the other skill books again, and now he had opened two books, and there were still four books waiting for him to open, so he was not in a hurry, and took his time one by one.

"Smack!"

After opening the third skill book, Mu Feng closed his eyes with expectant eyes and felt the information in his mind, this information was not as much as before, but it would take a certain amount of time to digest it.

Filson-9 amphibious RV production method (low-level); As the saying goes, people don't have a house and even a poor can't compare, people don't have a car and the mother-in-law won't look at you, but this means of transportation can be used as a house and a car, the mother-in-law will surrender to your feet when she sees it, it is not only loaded with luxury villas, but also luxury swimming pools!

Mu Feng; “……”

Is the description of this skill looking down on yourself?

What if he doesn't have a car or a house, anyway, it's enough for him to have Xia Qing......

"Although that being said, this vehicle is also real, judging from its design drawings, this amphibious type of RV should only be used in open areas, if I make it and put it in the person's backpack, then I will have a house to live in at any time?"

I have to say that Mu Feng's brain hole is indeed very strange, he has already guessed that this type of RV can only be used in open areas, that is to say, it can't be used in ordinary times, so as long as he puts the RV in the character backpack, it is equivalent to having a house that can be moved, and sometimes it can be used as a car!

If you think about it this way, this skill is also very good, this industrial type of skill not only includes the design drawing of the vehicle, but also the method of use, modification, maintenance, etc., Mu Feng can draw the design drawing with other skills, but he can't have the knowledge of maintenance.

It's like the design drawings he handed over to the army before, the design drawings only have the production method on them, but they don't say how to maintain and repair them, about this problem, Mu Feng also told the army, so before the army tests the repair and maintenance, even if the mecha comes out, it's useless.

"Smack!"

Soon, Mu Feng used the fourth skill book.

When the blue light disappeared, Mu Feng had a lot of memories in his mind, and accepting too many memories at one time made Mu Feng have a little headache, he gently rubbed his temples with his index finger, and then began to digest this skill.

How to make mecha transformation truck accessories (low-level); Using this skill, you can have the knowledge to modify the mecha, the mecha can also be modified, among the countless accessories, the transformation accessories are the most expensive, after manufacturing, the mecha can be like the transformer, not only can be worn on the body, but also can be turned into a vehicle.

PS； The accessory production method included in this skill can only be modified for the giant mecha, so that the mecha can obtain the same ability as the vehicle, and the small mecha cannot be used, so please look forward to the follow-up development......

"Holy! I'm worried that I can't find the accessories for the medium-sized giant mecha, but I didn't expect this skill to send me a production method, I just wanted to find this thing, I don't know why I don't have it in my mind, maybe it's because I haven't seen it! Mu Feng suddenly became ecstatic.

How awesome is this skill? Needless to say!

Anyone who has watched the movie Transformers knows that if the mecha and the Transformers work together, the effect is definitely better! In his previous life, Mu Feng had seen the giant mecha that could basically be transformed, so there were so many series.

And if the mecha also has the characteristics of a vehicle, then their human strength can also be greatly increased, and there is no need to worry that the medium-sized mecha cannot fly into the sky, as long as there is a design drawing of the accessories of the aircraft, but Mu Feng is a deformed part of the truck.

"If the next skill book ...... It's the production method of aircraft deformation accessories, and that's the real perfection! This way, I can make a mecha that can transform, whether it is running on land or flying in the sky! ”

With a feeling of apprehension, Mu Feng began to beat his heart faster, looking forward to the next skill book.

"Smack!"

Finally, the last industrial-type skill book was also opened by Mu Feng.

It's just that because Mu Feng had received the information of the previous skills, this time he suddenly had a headache, which made Mu Feng can't help but clench his hands, his face was bruised, and cold sweat broke out on his forehead, which made Mu Feng almost die of pain.

After a long while, Mu Feng's pain eased a lot, and he lay on the bed weakly, silently digesting the information in his mind.

Land vehicle production method (low level); This is a vehicle similar to an off-road vehicle, which can go over mountains and mountains, and can be driven over basically not very difficult ground, and the speed will become faster on flat ground, but the amount of fuel consumed will also be faster.

This last industrial-type skill book is even more rubbish than the previous ones, and even the flying machine can't be compared, which makes Mu Feng a little angry, he has suffered so much, he didn't expect to get this kind of skill, he is really unwilling.

"Forget it, in the five skills, three of the skills that surprised me are already very good, I should also be content, it's a big deal to buy the deformation accessories in the system store at that time, anyway, I still have 500 wealth left!" Mu Feng could only comfort himself.
