Upgrade to LV15 to unlock the subclass "Scavenger Kid", and the system rewards the stone with a blueprint of ordinary quality, "Fart Pump Truck", so theoretically, as long as he prepares enough materials, he can follow the map and build a car according to the map.

However, theories are always just theories.

Don't look at the eyes of ordinary orcs, the "fart pump pump truck" that will fall apart at any time is a broken toy of the five scum of the war, and it is useless to fight a war, but when the stone has to be made by itself in order to upgrade, it is not so simple at all.

No matter how dilapidated the car is, it is still a car, and even if there are drawings, it really can't be done without a little level.

At that time, the stone that was still in the "steel rock" was specially selected from the engineering brigade with short manpower, and a group of fart technicians were carefully selected from the engineering brigade with short manpower, and they worked together for almost a month before they crookedly built the first finished car after four failures.

In the process, Stone also discovered the reason why the efficiency is so outrageous, and that is these little farts spirits.

While they can do most of the work in their territory, it is still too difficult for them to build a war machine from start to finish, with a success rate of only twenty percent, and it takes so long.

In addition, the skill of the stone "The Power of My Search" does not play a role, this skill is now only level 1, and it can only increase the success rate by an additional 10%, which is equivalent to rising from 20% to 22%, which can be said to be very small.

Found the crux of the problem, how to solve it?

You must know that these fart mechanics have risen step by step from fart slaves, fart slaves, and fart sappers, and they can be said to be the strongest hands-on ability in the territory at present, and if they can't do it, there will really be no one left.

Fortunately, at this time, the system solved the urgent need, and just when the second fart pump truck was being difficult to manufacture, the stone received the news that a new fourth-level building in the "Iron Furnace Fort" was completed, and the problem was solved.

This building is where they are now.

【Goblin Workshop】

[Description: Industrial Building, +300 Development]

[Output: X10 goblin mechanics can be trained every week, which can increase the manufacturing success rate by an additional 20%]

[Goblin technology, shocking! ] 】

………

That's right, the goblin kid running around the room now is the latest tech talent in the territory, the goblin mechanic.

Although there is only a word difference, they are far higher than the original fart spirits in terms of theoretical knowledge and practical ability, and if the latter are manual laborers who move bricks on the construction site, then they are basically equivalent to junior workers who have just graduated from technical schools.

This analogy is also inaccurate, because even in terms of physical fitness, goblins can blow up fart spirits, and any goblin mechanic here can top the original five little farts spirits.

After the first goblin mechanics were put into use, the manufacturing speed and success rate of pump trucks began to increase.

On the one hand, with the bonus of the "Goblin Workshop", the success rate has reached a quarter, and the success rate is slowly increasing as more and more finished products are manufactured.

On the other hand, the speed increases faster. Now the number of goblin technicians in the territory has reached 60, and they can be divided into two groups to start work at the same time, and an average of two days can be used to build a pump truck, even if the current success rate is still average, two can be done in a week.

Of course, the stone will only make so many fart pump trucks when it is full, and these little junks have no meaning at all except for giving the little farts a good time, if they are really going to count on them to fight one day, it means that the "Broken Claw Tribe" has reached the time of life and death.

Although he already had another vague plan in mind, ten pump trucks were enough now, so he stopped the project as soon as possible.

There are no new drawings, and the pump truck is not built, and the goblin mechanics in the workshop have been disrupted and arranged to other strongholds in the territory in the past two months, and continue to shine.

Some went to Thunder Bluff to oversee the construction of the city walls, others to study new brewing techniques and recipes at Garkison, and most of the rest stayed in the industrial park of Ironforge to improve the manufacturing process of green bricks and cement.

Don't look at the fact that there are only sixty of them, but on the whole, it still greatly improves the technical strength of the territory, well, and at the same time, it also greatly increases the danger level of the territory.

Since being assigned to other places, the unsupervised goblin mechanic is like a bird, and he begins to fly freely in the sky of knowledge, at the cost of creating some movement from time to time, but fortunately, the destructive power is average, and it is still within the tolerance range of the stone, and he really has no time to care about this.

Ten pump trucks have been built, and the Black Orc has also become a scavenger boy in LV2, and the effect of "My Wisdom Power" has been doubled, which can increase the success rate by an additional 20%, but if you want to continue to upgrade, you have to find a way to come up with a new drawing.

If Ayigunu is here, it will be easy, with her ability, maybe she can draw ten or eight of them at hand, but the problem is that the devil knows when she will come back, and maybe the system must be a greenskin-style drawing?

I couldn't help it, and after thinking about it, the stone finally decided to paint it himself.

Then in the past two months, he fought with the big guys of the pro-guard team during the day, and at night he lay in the house and painted, and basically did nothing else.

But no matter in his previous life or in this life, he didn't understand drawing at all, so he had to follow the "fart pump pump" drawing rewarded by the system to teach himself, and try to draw it himself while imitating it.

As you can imagine, all the things drawn were judged to be unqualified.

It wasn't until that day that he and Old Rotten Tooth ran out of the city to meet the returning Greenskin and the Nezumi, and when he passed by the city gate, he saw several "Dive Destruction Catapults" mounted on them, and finally had inspiration.

There's something ready here, so don't you just get it by drawing it!!

So this time, Stone specially brought a catapult back to the "Iron Furnace Fort", and gathered all the goblin mechanics who stayed here to give the task.

As soon as they heard that they could dismantle the catapult and study it, they all lit up and acted immediately, and the stone also taught the old rotten tooth how to deal with the daily affairs of the stronghold, and rushed into the house, and drew drawings with the goblins.

The hard work paid off, with the foundation laid before, plus the finished product in front of him, and the help of the goblin mechanic, finally before Urzago entered the door just now, the stone successfully drew a drawing that was recognized by the system, and it was still a rare quality of green!

The "Dive Destruction Catapult" created from this drawing can increase the range by an additional 10%!

At the same time, the system prompts that you only need to build ten units, and the sub-class of the stone can be upgraded to another level!

In addition, due to his rare green drawings, he was given a new follower slot.
