Who was the earliest carpenter in human history? Certainly not Lu Ban, but ordinary carpenters regard Lu Ban as their ancestor.

Liu Changan is not a professional carpenter, nor does he recognize Lu Ban as an ancestor, but he still appreciates a capable person like Lu Ban, and has nothing to do with the so-called craftsman spirit, but lies in the spirit of creation and innovation, although many of his inventions have now had more advanced alternatives, but Liu Changan remembers that just twenty or thirty years ago, the majority of carpenters who used Lu Ban's inventions such as curved rulers, ink fountains, and planers are still very active.

The carpenter profession is not thriving at present, and it is rare to be able to hype up the spirit of craftsmen, mixing than pots, making kitchen knives is not as good as some, and so on in the future 3D printing is more popular, carpenters for many years of hard work to be able to master the various carving processes, naturally will be forgotten by the popularization of science and technology.

In fact, many exquisite woodworking carvings are no longer done by craftsmen.

Similarly, there are paper-cutting, many complicated paper-cutting crafts to the extreme, and there may be only ten or eight people in the country who can have such a top level, but for the machine, three minutes to learn to operate, input drawing data, and no matter how complex the finished product is ten times, it can be made by a primary school student.

The primary school students here do not include Zhou Dongdong, after all, she is only a quasi-primary school student, and she is extremely stupid, what others can learn in three minutes, she may spend ......

In general, all the transcendence achievements of technological innovation are overtaking in corners, so to surpass a country that has mastered the authority and standards of old technology, it is necessary to make great progress in the field that can erect new standards to be able to surpass, otherwise it will always be just a chaser.

For example, the Indians are very smart: if others build aircraft carriers, we can develop Star Destroyers first.

Liu Changan still uses a hand saw and planer, working slowly and meticulously, doing repair work unhurriedly, in fact, you can buy a new table for a few dozen yuan, but in that case, it doesn't seem to be interesting, Zhou Dongdong's purpose is not to have a new table, but a repaired old table...... Therefore, it can be seen from this small incident that modern human beings are not made with a logical basis as the core, or that the assembly line that makes human beings adds a reaction system beyond Liu Changan's understanding.

"Zhou Dongdong, are you a robot?" Liu Changan looked at the child who wanted to intervene to help, but in fact only made trouble.

"I am! I am who I am!"

"Then I'm going to turn your power off. ”

"No!"

"Smack, it's off. ”

"I'm turning myself on again!"

"How can there be a robot like you?"

"That's what I am. ”

Such a robot is really annoying, Liu Changan was ready to paint, lifted the robot to sit under the plane tree, and told her that if she is obedient, she will have delicious food, and this robot who does not listen to orders is finally honest.

Liu Changan painted the paint and did not hang the table on the tree, but put it on the top of the carriage for ventilation.

Zhou Dongdong still sat next to the puddle and fed the loaches tofu slag, and asked Liu Changan: "Brother Chang'an, will there be thunder today?"

"No, it won't. Liu Changan looked at the weather and shook his head.

Zhou Dongdong looked at the loaches in the puddle very happily and pursed his lips again.

Liu Changan also looked at the loaches by the way, Zhou Dongdong fed the loaches very dedicated, these loaches have grown fat and round, since he came out of the college entrance examination results, he has not sent a little hen to Shangguan Tangtang, and now more than a month has passed, Shangguan Tangtang has not shown any discomfort.

Could it be that after she sobers up, absorbing vitality and blood is already dispensable for her?

Change Ming'er and throw a little hen into the experiment, Liu Changan thought so, and then turned his head to see the sunset wrapped in a similar face, Xin Qiji's poem came to mind in an instant, his sleep was calm most of the time, and he never looked for her in his dreams.

A few stones under Liu Chang'an's feet fell into the puddle, stirring up a flutter of loaches, thinking that it was the bean dregs dropped by Zhou Dongdong, Liu Changan looked down, there was no strong reflection on the water surface under the shade of the tree, not that he was dazzled.

But she has passed away, her bones were found after the founding of the People's Republic of China and reburied, no one can be resurrected, after all, traveling through time and space is only the privilege of future human beings, the beautiful woman a hundred years ago, and the countless thin lives in history are no different, a flash in the pan, the waves dotted in the long river of time, and then the long river continues to move forward, the waves are only in memory, remember or do not remember.

"Jin...... ...... children"

Liu Changan's lips opened slightly, making a almost inaudible sound from his throat, his eyelids slowly raised, and he reached out and picked up a splash of water and slapped it on his face.

"What are you doing?"

The familiar voice is cold, with a completely different delicacy when you are with someone close to you, and there is a bit of smugness and banter, as if you can't help laughing.

Liu Changan came back to his senses, showed a smile, didn't look back, just looked at the plane tree in front of him, raised his sleeve and wiped his cheeks.

It's Qin Yanan, not Ye Sijin.

Zhou Dongdong picked up a splash of water and slapped it on his face, it was not fun at all, and then wondered, what was Brother Chang'an doing just now?

"Zhou Dongdong, what are you learning from him for?" Qin Yanan quickened his pace a little, this big and small squatting next to the muddy puddle and splashing his face with water was really strange.

Liu Changan's reaction just now must have misunderstood that she was Ye Sijin, which made some doubts in Qin Yanan's heart even worse, but this was the effect she wanted, Qin Yanan was sure that even if Liu Changan saw An Nuan wearing a cheongsam, he would not lose his mind like just now.

"I thought it was fun!" Zhou Dongdong said disappointedly.

Qin Yanan couldn't understand Zhou Dongdong's brain circuit, this water is not clean, one big and one small brain are not very normal.

"I'm back. Liu Changan turned his head and looked at Qin Yanan who was wearing the customized cheongsam that was "explaining" with his usual gentle and ordinary smile.

Qin Yanan is one of the few beautiful women Liu Changan knows who does not have bangs, and the other is Liu Yuewang, like An Nuan, a girl of Zhu Juntang's age, naturally likes the feeling of bangs, and the third wife also has a hairstyle with bangs when she sees her several times.

Bangs are very important for girls, and many girls especially hate others to play with her bangs, because it will make her look completely different, and even make her panic, afraid that she will show a different and ugly appearance in front of others and become not herself.

It's not that girls with bangs and look good must not look good when they put their bangs away, it's just that many girls feel that if their heads are not covered, they will look out of tune with their little faces.
