It was precisely because of the magnet of Luban No. 7 that he and the black mother sat on the shoulders of the shield mountain and walked to the hinterland of the valve, and the black mother almost poisoned the poisonous spider of the king of Cangluo into a nervous disease.

But for this reason, the black mother lost the magnet, and Luban No. 7 is intestines are all regretted, regretting that he shouldn't have handed over the magnet to the black mother in the first place, and it is not too late to take it out when the search has eyebrows, but he trusts the black mother so much......

After such a big incident, the black mother didn't blame herself or feel sad, but she laughed inexplicably, and said a lot of nonsense, Dunshan and Luban No. 7 looked at each other, thinking about the same question in their hearts: Should the poison of the cobwebs actually poison the black mother, but it is only now, right?

It's a pity that the two of them are expressionless, and the black mother can only judge from their eyes whether they believe their words or not, and the answer is no, so she has to patiently explain: "Dunshan's analysis is not wrong at all, with my little strength, I am under attack, and I am in a state of panic, and I can't throw the magnet too far." But don't forget the chip, although that thing is small, it is not an ordinary flake, if you encounter something that repels it, the repulsion is amazing! ”

Only then did Dunshan understand what Hei Mu meant, and couldn't wait to ask: "So according to what you said, it was actually the chip that pushed the magnet out?" ”

Luban No. 7 also came to his senses and shouted cheerily: "The chip was designed by your hands, so tell me quickly, what is its maximum thrust range?" Is it ten zhang or one hundred zhang? ”

"Huh? This ......" is really a master of creation, and when asked about the topic of this industry, it is a professional than Dunshan, but the black mother can't answer. He knows the chip material he uses, and he has never done suction or repulsion tests! That thing wasn't meant to be used as a magnet in the first place......

Seeing that the black mother was speechless, Luban No. 7 did not force him, but dug in his cross-body waist bag for a long time and took out a tube.

"Hey, what's that baby?" Seeing this, the black mother asked curiously.

Dunshan actually recognized it, and asked puzzledly: "Seventh brother, what are you doing with the fish scale dividing line?" ”

Luban No. 7 replied seriously: "If Brother Hei's speculation is correct, even if we are a blessing in disguise and take a big step forward, as long as we find the magnet, it is equivalent to setting the position of the chip, and we will be able to find it soon." When I was using magnets for mechanism tests, I applied a gel with fish scale dividing lines on them, so I could analyze the distance from the magnet by how luminous the gel was. ”

"Ahh It's amazing! Dunshan is full of praise for these small inventions of Luban No. 7.

The Black Mother glanced at the Ark III spaceship he had built, and sighed secretly: "Hey, even a piece of iron here was built by me myself, why doesn't Dunshan never praise me?" ”

Thinking about it, he didn't notice that Lu Ban No. 7 had applied the gel to the tips of his two straw sandals.

"Hey, Xiao Qi, your baby, why don't you wipe it yourself, you want to wipe it on my shoes?" The two of them were completely unaware of the black mother's jealousy, but they could feel that his vicious voice was quite unfriendly.

Luban No. 7 rolled his eyes and said angrily: "Aren't we looking for your chip?" What's the use of coating my feet? You can't ask me to tell you when I find out, right? ”

"You ......" Hei Mu is also on fire, these two are not very good-tempered, they are not easy to provoke, and now they have become needle-to-wheat, and they are about to quarrel......

"Oh, okay, okay, when is this going on, why are you still infighting? If you are afraid of suffering, will you smear my feet? "Dunshan came out to be a peacemaker, but he was also very angry, and he felt that these two were too disregarded about the overall situation.

The mecha man came forward, the black mother and Luban No. 7 didn't dare to squeak, and the black mother honestly let Luban No. 7 finish the work, then shook her legs with a black face and strode forward.

This time, Luban No. 7 walked side by side with him, and his eyes never left the two gels. Dunshan followed them closely behind as bodyguards to prevent any foreign objects from raiding.

The gel always has an orange-yellow sheen and looks shiny.

Hei Mu pointed to her toes and said, "Xiao Qi, your snot is so bright, it will have to be darkened when it gets stained with gray, right?" ”

"Snot?!"

Luban No. 7 almost jumped up and said angrily: "Brother Hei, if I compare your laboratory to a coffin, are you willing to listen to it?" ”

"Ah~ Okay, it's my fault, I apologize, but it's slippery and greasy, it really looks a bit like it~" The black mother annoyed others, and she was quite aggrieved.

Lu Ban No. 7 said viciously: "Dust naturally can't make it dark, but magnets can!" Now what you see is not called light, it is called light, because it leaves the distance that can be sensed by the magnet, so it emits a warning light, but when it enters the sensing range and is close to the magnet, the light will become weaker and weaker until it becomes gray-black. ”

"Oh oh~ It's been a long time, it turns out to be such a principle! It seems that Xiao Qi's invention is indeed two times, I am jealous that he gave him a look, it is my fault......" Hei Mu finally blamed herself, and her tense face eased.

Luban No. 7 didn't hold grudges at all, and when he saw that Hei Mu spoke kindly, he didn't bother with him anymore, and the two concentrated on studying the fish scale dividing line.

It was only after walking out for nearly 200 zhang that the fish scale dividing line reacted, and the bright orange began to dim a little.

"Ah~ Great! The magnet must be around here! "Luban No. 7 was very happy.

Dunshan didn't have the strength of him, and muttered: "Three hundred zhang range, is it small?" Even if I could be sure, it would be big enough! ”

"Huh? And three hundred zhang? The black mother was shocked, and she didn't know why she wanted to get such a big repulsive silica to assemble the chip......

Luban No. 7 was extremely relaxed, turned his head to Dunshan and said: "Brother Tie Silly, don't worry, the distance of three hundred zhang was set by me for you last time, and this value is not fixed." Originally, the magnet was very close to my experimental object, and the spacing needed to be very precise, so my setting value was very small, only five or six inches long! ”

"Ahhh~ only five or six inches? Doesn't that mean that the magnet is already at our fingertips?! ”

Without waiting for Dunshan to answer, the Black Mother jumped three feet high excitedly.

Luban No. 7 said happily: "Yes, it can be understood in theory. However, the demarcation line of fish scales has just begun to fade, and we still have to continue to observe how far we have to go to completely fade to gray-black! ”

Hei Mu's confidence doubled, and she waved her hand again and again: "It's okay to do it, let me go faster, so that I can save a lot of time!" ”

After that, his two little short legs struggled to run forward, and the dividing line of fish scales really became darker and darker, and the lost magnet was found!
