If she can help her brother, Lu regrets that it is naturally incumbent on her, and she ran to Lu Donglai's side excitedly and said, "Brother, what do you need me to do?"

Lu Donglai pointed to the bamboo in front of him, and then said, "It's a pity, aren't you building a foundation?" Then can you help me cut these bamboos, the same length, different widths are a little bit." ”

Lu Donglai needed carbon filament, but he didn't have any idea of the size of the carbon filament produced after the bamboo was burned.

In physics, anything uncertain must be tested repeatedly to get the correct answer, and Edison didn't know how many experiments he did before he completed the invention of the electric light.

Failure is the mother of success, in comparison, Lu Donglai borrowed the foundation of his predecessors, which can be said to have taken a lot of detours.

Although Lu regretted that she didn't know why, she never knew how to refuse her brother's request, since her brother said that she would divide the bamboo into countless parts, she naturally did it.

A layer of mist bloomed, instantly enveloping the entire bamboo, and then Lu regretted closing his eyes, this kind of cutting ability is much more complicated than killing, but for Lu regret, it is naturally not a problem.

This bamboo is wood, but it doesn't have to be able to turn it into water.

All the water mist wraps the bamboo, and all the structures in the bamboo are like a 3D net analyzed in Lu Xi's mind.

Woohoo~!

In an instant, countless bamboo sticks of different lengths, sizes and widths appeared in front of Lu Donglai.

"Humanoid toothpick machine!"

Lu Donglai let out a sigh of emotion.

"Brother Donglai, what are you talking about?" Lu looked at Lu Donglai with an innocent look.

Lu Donglai smiled slightly, rubbed Lu's regretful little head and said, "It's nothing." ”

After saying this, Lu Donglai took all the bamboo sticks in front of him in his hand, and then returned to the house, followed by Lu regretfully.

Lu Donglai sat on a chair and began to burn it with the thinnest bamboo.

After the bamboo was burned, there was hardly any left, not even a residue.

Lu regretted sitting opposite Lu Donglai, holding his chin with both hands, and looked at Brother Donglai with curiosity, not knowing what Brother Donglai was doing, but it seemed to be very powerful, could it be that he was studying some powerful magic circle, or that he was studying those terrible things...... It's so powerful, it's so powerful!

In the world where Lu regrets children, his brother is omnipotent, and his brother is powerful.

Lu Donglai didn't know that he borrowed the achievements of others and had such an idea in Lu Regret's mind, if he knew, he would probably feel extremely embarrassed, after all, the person he was most unwilling to deceive was Lu Regret.

This is the first time he has felt affection in this world, and Lu regrets that he and his sister in the previous life are almost carved out of a mold, except for the appearance is not very different, other aspects make Lu Donglai feel the shadow of his sister.

One carbon filament burned out, two carbon filaments burned out, and three carbon filaments burned out...... After trying more than 20 times in a row, when there was finally a size similar to the prototype of the carbon filament in the previous life, Lu Donglai found a thicker bamboo skewer and burned it, and it took him more than an hour to finally find the most suitable burning volume.

"It's a pity that according to this size ratio, I will get about ten bamboo sticks for my brother. Lu Donglai took out a brush and scratched it on the paper, Lu regretted that he understood, and immediately nodded, "Don't worry, brother." ”

If the carbon filament is too thin, it is easy to oxidize with the oxygen in the air, which greatly reduces the use time, and if it is too thick, it will affect the luminosity.

When Lu regretted remaking bamboo sticks, Fang Qinghal also rushed to Qilin Mountain.

She is now a frequent visitor to Qilin Mountain, and the four masters are also familiar with her, as for the crow Taoist who guards the door, he caught a glimpse of Fang Qinghal, and ignored her, the boss's woman, she can't move, and she can't go up to talk, if this woman complains in front of the boss......, what can she do? The boss seems to hate absent employees the most.

Obviously, the Raven Dao people are quite self-aware.

Fang Qingzhen jumped all the way into Lu Donglai's room, and when he rushed in, Lu Donglai was stunned for a while.

His eyes looked at the door, and then at Fang Qinghal, but he couldn't laugh or cry.

Fang Qingzhen noticed Lu Donglai's gaze, his face turned red, and then he said with a big grin, "Senior Brother Lu, because you were a little anxious in the communication beads, I thought you were desperate to want those things, so you didn't knock on the door and came in, and I hope Senior Brother Lu will forgive me." ”

Where will Lu Dong come to give birth to Fang Qinghal's anger, the other party is tired of running around for herself, and she is an outstanding representative of modern young women, and she has a fine sweat on her face, and the original thin shirt is a little transparent because of the sweat soaking, and the weak waist looms in it, as well as the skin that clings to the clothes, it seems that the other party is indeed going to work immediately after her communication, and she is not slacking off at all.

Lu Donglai didn't make ripples, but he was moved, "Senior Halal, let's drink a glass of water first." ”

Fang Qinghal saw the two glasses of water on the table, and without thinking about it, he directly took one and dried it.

Lu Donglai's expression was a little embarrassed, the glass of water seemed to be his own......

Fang Qingzhen also seemed to realize something, and her face suddenly became extremely ruddy, but she quickly changed the topic and took out a few things from her body and put them on the ground, "Senior Brother Lu, are these things what you want?"

Since Fang Qingzhen didn't want to mention this matter again, Lu Donglai naturally wouldn't take the initiative to mention it.

When his eyes fell on the things on the ground, he picked up a bottle, the bottle in front of him was slightly larger than a normal light bulb, but because of Lu Donglai's drawings as a reference, this glass bottle was barely qualified, as for whether it was breathable, Lu Donglai believed that Fang Qinghal would not be sloppy at this point.

Nodding slightly, Lu Donglai said, "That's right, this is the glass bottle I need." ”

It can be seen that when Lu Donglai affirmed the glass bottle, Fang Qingzhen's nose moved, obviously relieved, and at the same time with a faint smile on his face, being able to get Senior Brother Lu's affirmation was the greatest encouragement to her.

At this time, Fang Qingzhen pointed to a pile of stones on the ground and said, "Senior Brother Lu, I bought these useless residues according to your request, but these things don't cost a few dollars, what does Senior Brother Lu do with them?"

Lu Donglai raised his head slightly, "Electric light." (To be continued.) )
