Lin Yuan's audio-visual radar has an accurate coverage range of only fifty meters, so once it exceeds this distance, the stereo projection will become a little blurred, and even a little delay in the return time.

Lin Yuan tried it and found that the exploration limit of audio-visual radar should be between 300 and 400 meters, so he really couldn't determine whether this was the earth through the sun in the sky?

In fact, within this distance, Lin Yuan could only find those particularly eye-catching objects. It is fine to use them to see the road, but it is impossible to be alerted. If an enemy attacks fifty meters away, he can only stare at him.

After understanding this, Lin Yuan immediately let his body hide behind large pieces of rubble. After all, this is not a game, and there is no chance to go back on his word. Perhaps a small mistake will lead to death.

But then Lin Yuan found that he encountered another great difficulty, that is, in this kind of rubble-covered ruins, his two wheels had no use at all. If he really needed to move forward, he could only rely on the assistance of two robotic arms.

"No! So unlucky! A precious transformation point wasted! What should I do now? If I don't upgrade, there will be no transformation point at all, but if it is like this, let alone a turtle, even a snail can't escape!" Lin Yuan was really anxious now. If he didn't seize the time to collect energy from the ruins, something might happen at any time.

"Oh! If you have the function of the floating bicycle to walk in the desert, you won't have to make such a difficult situation! Huh? Walk in the desert!" Lin Yuan suddenly remembered that useless skill, level 0 maintenance. If he could assemble two mechanical legs on his body and cooperate with the robotic arms, he might be able to adapt to this terrain!

Without any hesitation, Lin Yuan ran back to the underground warehouse. Now most of the parts on his body have been used, so if he wants to assemble mechanical legs, he can only disassemble other bicycles. Fortunately, the one he lacks the least here is bicycles.

But it is simple to say, but it is very rare to do. Lin Yuan's current strength and two movable wrenches are enough to dismantle a bicycle, but assembling them really requires testing his level 0 maintenance skills.

After a scramble of noises, the two bicycles were dismembered wildly. Lin Yuan looked at the broken parts on the ground, but 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 limitations, there is neither electrical welding nor more refined tools, these two mechanical legs can only sacrifice their flexibility and divide them into two sections, barely completing a simple bending and stretching action.

Secondly, the joints of the mechanical legs must be overcome, which is the key to whether their strength can be accurately executed. However, due to limited conditions, it can only be replaced by the simplest moving screws. Although this efficiency will decrease a lot, it will at least work.

Moreover, Lin Yuan planned that these two mechanical legs only need to meet the support function, and the real power output is two mechanical arms.

After confirming the assembly plan, Lin Yuan immediately assembled it. After more than an hour, two extremely simple mechanical legs appeared in front of him. According to his estimates, they could basically do two flexion and extension movements, but the delay time of each mechanical legs was at least 5 seconds, and it was 10 seconds together.

And if you want to do a whole set of actions, it will probably take more time.

"No! Even if these two mechanical legs are installed, the speed is probably a little faster than that of a snail!" Lin Yuan thought depressedly.

"Rework! I don't believe that I can't make two suitable mechanical legs!"

Lin Yuan, who had no choice, continued to waving his two mechanical arms and dismantled the bicycle, and the entire underground warehouse once again made a "cracking" sound.

More than twenty hours later, the entire underground warehouse was in a mess. Except for the floating bicycle, the rest of the bicycle was dismantled into pieces by Lin Yuan.

However, his efforts were not in vain. After dozens of failures, he finally made two relatively standard mechanical legs with the bracket of a folding bicycle. Of course, the main reason for his success is that the frame of the folding bicycle itself is very qualified, otherwise Lin Yuan would not have been so smooth.

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

"The basic maintenance skills are full, and the first-level transformation skills task is triggered. Are you accepting it?"

"Renovation skills? What is it? Could it be that it is a skill with the same nature as the transformation point?" Lin Yuan immediately remembered the transformation point. Now he knew that it was definitely a super good thing! Unfortunately, it was only available when upgrading. Unexpectedly, he actually triggered such a rare task now?

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

"Ding! Level 1 transformation skill task requires the following conditions."

"One, upgrade to F3 level mechanic warrior; two, upgrade to level 10; three, self-strength reaches 15."

"Note: This task is an active selection task. If you choose to give up, there will be no punishment, but the subsequent triggered task will not appear again!"

"This - the conditions are too high and difficult!" Lin Yuan was speechless after reading it. These three conditions were no longer harsh for him at this moment. He doesn't know how to upgrade now, how can he become a F3-level mechanic warrior?

You should know that although he is now a F1 mechanic warrior, he knows very well that a real F1 mechanic warrior will definitely not be so weak.

The reason why he was so eager to look forward to this transformation skill was that he wanted to get a strong body to save his life? Otherwise, how could he be upgraded to F3 level under his current situation? It would probably not take long to die.

As for the second condition, it sounds very simple, because Lin Yuan is already at level 7 now, and there is only a level 3 gap between them. But the problem is that he does not believe that his soul has this potential, just like not believing that a guy with an IQ of 30 can be trained to become a Nobel Prize winner in a short period of time!

In comparison, the third condition is the easiest, because with that mechanical wreckage, as long as he can advance to a F2-level mechanical warrior, he can use the transformation point to strengthen his body.

Although he cursed this perverted mission tens of thousands of times in his heart, Lin Yuan decided to complete this mission as much as possible. This is not only because he urgently needs the transformation skill, but also because there are subsequent missions in this mission!

In addition, Lin Yuan has another consideration, that is, to figure out whether the skills of the mechanic warrior are given up with the upgrade like a transformation point, or are there other triggering conditions?

Also, if I had not placed the two movable wrenches on the robotic arm at the beginning, but replaced them with two weapons, I wonder what kind of skills would appear?

After finishing two mechanical legs, Lin Yuan planned to go out of the underground warehouse to explore the surrounding environment. As for the skill transformation task, he does not have the ability to complete it now, so the most urgent task is to search for enough energy to deal with emergencies.

"Hey! Look at how effective these two mechanical legs can play?" Lin Yuan first put down the mechanical legs, and then put the two wheels in the air with the cooperation of the mechanical arms. He looked like a four-legged spider, very strange!

"Haha! Go forward!" Lin Yuan shouted proudly in his heart. This was the mechanical leg he had made successfully, and its meaning was very valuable.

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

"This is not possible! These two mechanical legs seem to be somewhat repelled from their own body! After the order was issued, there was a delay of one second, and what was even more serious was that the flexion and extension of the two joints was not ideal."

Faced with this bad result, Lin Yuan was really depressed. This was the limit of his transformation, but this speed was at most a little faster than a turtle, let alone chasing a rabbit!

"Huh? Rabbit?" A sudden light of inspiration flashed in Lin Yuan's mind. Since he had not been able to learn from the human body, why not learn from animals in nature? For example, the way the hare runs!

Lin Yuan recalled in his mind that the two front legs of the rabbit are very short and do not seem to be very flexible, but it has a pair of flexible and powerful hind legs, so it only needs to use the hind legs to bounce, and the front legs mainly play a supporting role.

And I don’t need two mechanical legs to be very flexible, so the task of bounce is given to two mechanical arms. After such a long time of training, the flexibility of the two mechanical arms is no longer the same as before. More importantly, there is no delay in commanding my soul, so that the entire bounce process can be completed better.

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

As soon as he thought of this, Lin Yuan quickly changed his method, shifted his body's center of gravity to the two mechanical arms, and then accumulated power and bounced up!

"Bang!" There was no suspense at all. Lin Yuan fell directly to the spot, not even a centimeter away.

"Strange? What's going on? The two robot arms have no delays, and the power they use is exactly the same. There is no reason why they can't jump up?" Lin Yuan thought with some distress, "Is it because of the different angles? Yes! It must be the reason!"

After climbing up from the ground, Lin Yuan did not jump immediately, but thought about the moment just now, and kept adjusting in his heart.

A few minutes later, Lin Yuan conducted a bounce test again. This time it went smoothly, but unfortunately the height and distance of the jump were still not ideal.
Chapter completed!
