Lin Yuan's audio-visual radar has an accurate coverage range of only fifty meters, so once this distance is exceeded, the stereo projection will become a little blurry, and even the return time will be a little delayed.

Lin Yuan tried it and found that the exploration limit of the audio-visual radar should be between three hundred and four hundred meters, so he really couldn't determine whether this was the earth by the sun in the sky?

In fact, at this distance, Lin Yuan could only find those particularly eye-catching objects, which were usually used to see the road, but it was impossible to be vigilant, and if an enemy attacked from fifty meters away, he could only stare dryly.

After understanding this, Lin Yuan immediately let his body hide behind a large piece of rubble, after all, this is not a game, there is no chance to regret it again, maybe a small mistake will lead to death.

But then Lin Yuan found himself encountering a great difficulty, that is, in this kind of rubble and ruins, his two wheels were useless at all, and if he really needed to move forward, he could only rely on the assistance of two mechanical arms.

"No, it won't! So unlucky! A valuable transformation point was wasted! Now what? If you don't upgrade, there is no transformation point at all, but if it looks like this, let alone a turtle, even a snail can't run! Lin Yuan was really in a hurry now, if he didn't hurry up and collect energy from the ruins, maybe something would happen at some point.

"Alas! If only that hoverbike had the ability to walk in the desert, it wouldn't have to be so difficult! Hey? Desert walking! Lin Yuan suddenly remembered that chicken rib skill, level 0 maintenance, if he could assemble two mechanical legs on his body, and then cooperate with the mechanical arm, maybe he could adapt to this terrain!

Without any hesitation, Lin Yuan ran directly back to the underground warehouse, and now most of the parts on his body have been utilized, so if you want to assemble the mechanical legs, you can only disassemble other bicycles, but fortunately, the most important thing here is the bicycle.

However, it is easy to say, but it is very rare to do, with Lin Yuan's current strength and two movable wrenches, it is enough to disassemble a bicycle to pieces, but reassembling them is really a test of his level 0 maintenance skills.

After a "crackling" sound, the two bicycles were savagely dismembered, Lin Yuan looked at the broken parts on the ground, but he was a little dazed, now he really missed the cute transformation point very much.

After thinking hard for a long time, Lin Yuan finally came up with an assembly plan, first of all, due to technical constraints, there is neither electrical welding nor more refined tools, so these two mechanical legs can only sacrifice their flexible surnames, divided into two sections, and can barely complete a simple flexion and extension action.

Secondly, it is necessary to overcome the joints of the mechanical legs, which is the key to whether his strength can be accurately executed, but limited to the conditions, can only be replaced by the most rudimentary movable screws, although this will reduce the efficiency a lot, but at least it can work.

Moreover, Lin Yuan planned that these two mechanical legs only needed to meet the role of support, and the real power output was two mechanical arms.

After determining the assembly plan, Lin Yuan immediately started to assemble, and more than an hour later, two simple mechanical legs appeared in front of him, according to his estimates, they can basically bend and stretch two movements, but the delay time of each mechanical leg is at least 5 seconds, and the total is 10 seconds.

And if you want to make a whole set of movements, I'm afraid it will take more time.

"No, it won't! Even if these two mechanical legs are installed, the estimated speed is only a little faster than that of a snail! Lin Yuan thought depressedly.

"Redo! Lao Tzu doesn't believe that he can't make two suitable mechanical legs! ”

Lin Yuan, who had no choice, continued to wave his two mechanical arms and dismantled the bicycle, and the entire underground warehouse sounded a "click" sound again.

Twenty hours later, the entire underground warehouse was already in a mess, except for the hovering bicycle that was still intact, the rest of the bicycles were dismantled into pieces by Lin Yuan.

However, his efforts were not in vain, after dozens of failures, he finally used the bracket of a folding bicycle to make two more standardized mechanical legs, of course, the main reason for the success is that the frame of the folding bicycle itself is very qualified, otherwise Lin Yuan would not be so smooth.

When these two mechanical legs were installed in the center of the wheel, with a soft sound, a piece of information appeared in Lin Yuan's mind.

"The basic maintenance skill proficiency is full, and the first-level transformation skill task is triggered, do you accept it?"

"Retrofit skills? What is it? Is it the same skill as the transformation of the caste? Lin Yuan immediately remembered the transformation point, and now he already knew that it was definitely a super good thing! It's a pity that it's only available when you level up, but I didn't expect to trigger such a rare task now?

"Yes! I accept! Lin Yuan agreed without any hesitation.

"Tick! For the Level 1 Transformation skill task, the following conditions need to be completed. ”

"One, upgrade to F3 level mechanical warrior; Second, the level of the brain is increased to level 10; Third, the self-enhancement reaches 15. ”

"Note: This task is an active selection task, if you choose to give up, there will be no penalty, but this subsequent trigger task will not appear again!"

"It's—it's too high, isn't it?" Lin Yuan was completely speechless after reading it, these three conditions were not harsh for him at the moment, he didn't know how to upgrade now, how could he become an F3 level mechanical warrior?

You must know that although he is now a nominally F1-level mechanical warrior, he knows very well that a real F1 mechanical warrior will definitely not be so weak.

And the reason why he is so eagerly looking forward to this transformation skill is not that he hopes to get a strong body to save his life? Otherwise, how could he be upgraded to F3 in his current situation? It is estimated that it will not be long before it dies.

As for the second condition, it sounds very simple, because Lin Yuan is now level 7, and there is only a gap of level 3 in between, but the problem is that he doesn't believe that his soul has this potential, just like he doesn't believe that a guy with an IQ of 30 can become a Nobel Prize winner after training in a short period of time!

Comparatively speaking, the third condition is the easiest, because with that mechanical wreckage, as long as he can advance to become an F2-level mechanical warrior, he can use transformation points to strengthen his body.

Although he cursed this perverted task tens of thousands of times in his heart, Lin Yuan still decided to complete this task as much as possible, not only because he urgently needed that transformation skill, but also because there was a follow-up mission to this task!

In addition, Lin Yuan had another layer of consideration, that is, to figure out whether the skills of the mechanical warriors were given away with the upgrade like the transformation point, or whether there were other trigger conditions?

Also, if I hadn't placed those two wrenches on the mechanical arm in the first place, but replaced them with two weapons, I wonder what kind of skills would have appeared?

After getting the two mechanical legs, Lin Yuan planned to go out of the underground warehouse to explore the surrounding environment, as for the transformation skill task, he didn't have the ability to complete it yet, so the top priority was to search for enough energy to deal with emergencies.

"Hey! See how useful these two mechanical legs can be? Lin Yuan put down the mechanical leg first, and then with the cooperation of the mechanical arm, the two wheels were lifted into the air, which looked like a four-legged spider, very weird!

"Haha! Advance! Lin Yuan shouted proudly in his heart, this is a mechanical leg that he has successfully made by himself, and the meaning it represents is very valuable.

"Well, the first joint is bent down forty-five degrees, the second joint is lifted up, then falls, and the first joint is lifted again......" After a tedious struggle, it took Lin Yuan a minute to move forward a distance of about five or six meters.

"This won't work! These two mechanical legs seem to be a little repulsive to their own body! After the order was given, there was a delay of one second, and what was even worse was that the flexion and extension of the two joints was not ideal. ”

Faced with this bad result, Lin Yuan was really a little depressed, this was already the limit of what he could transform, but this speed was at most a little faster than a tortoise, let alone chasing a rabbit!

"Huh? Rabbit? Lin Yuan's mind suddenly flashed a spiritual light, since borrowing from human bodies was unsuccessful, why not learn from animals in nature? For example, the way a hare runs!

Lin Yuan recalled in his mind that the hare's two front legs were very short, and it didn't seem to be very flexible, but it had a pair of flexible and powerful hind legs, so it only needed to use the hind legs to bounce, and the front legs mainly played a supporting role.

And I don't need how flexible the two mechanical legs are, the task of bouncing is handed over to the two mechanical arms, after such a long time of training, the flexibility of the two mechanical arms is no longer what it used to be, and more importantly, there is no delay in the command of one's soul, so that the entire bouncing process can be completed better.

The most important thing is that he is not human, so there is no difference between the front and back of the head, the front and back are the same for him, as long as the audio-visual radar can transmit back the image in time, everything is OK!

As soon as he thought of this, Lin Yuan hurriedly changed his way and shifted the center of gravity of his body to the two mechanical arms, and then charged up and bounced!

"Bang!" There was no suspense at all, Lin Yuan fell directly on the spot, and he didn't even jump out of a centimeter of distance.

"Strange? What's going on here? The two mechanical arms don't have any delay, and they use exactly the same force, so there's no reason why they can't bounce? Lin Yuan thought with some distress, "Could it be that the angle is different?" Right! It must be this reason! ”

Getting up from the ground, Lin Yuan didn't bounce immediately, but carefully recalled the moment just now, and at the same time kept adjusting in his heart.

A few minutes later, Lin Yuan performed the bounce test again, and this time it was really smooth, but unfortunately the height and distance of the jump were still not ideal.

Lin Yuan didn't care about this at all, and kept bouncing, observing the state of the two mechanical arms and mechanical legs at the same time, and adjusting them at any time.
