The word "Ding" in Mi Qiao's hand disappeared synchronously as the animation "Ding Ling" in the Ruyi flame screen in Jiaoyue's hand disappeared and exited.

Immediately afterwards, there was another one that looked a little similar to the "Ding", but the whole shape was round, especially the three fat pointed taper feet with the appearance of the pier, the cone itself was empty, not like the three-legged solid of the "Ding", and the whole instrument was round and bulging like the buttocks——— which was not very elegant——— to correct it, just like the peach, and inlaid with a thin briefs shaped pants——— which seems to be a not very elegant metaphor, but it is indeed a very accurate and similar shape, so describe it for the time being!

"This is the 'Mustache Spirit', which has the same sound as 'Li', with two ears and three legs, sleek feet and empty objects, and the waist line is decorated and carved finely, and it is suitable for roasting and cooking. In this mustache, all walls are heated evenly, not only at the bottom. ”

If "Ding Ling" is like an iron Han, clumsy and cute; This 'mustache spirit' is like a woman who wears a "one-step skirt" to tighten her waist and fat buttocks, squirming proudly, making people want to laugh.

Shu Kang took the word "鬲" and took a closer look, that is, "separation" is one less ear! Remember! One less ear, it "stands", so that the glyph and pronunciation are synchronously burned into the brain successfully!

The most interesting thing is that this "Mustache Spirit" seems to be a little perfunctory about this appearance, and after twisting it twice, he made an expression of wanting to catch up with the "Ding Spirit", and hurriedly disappeared and went down.

If it weren't for the appearance of the one behind, I don't understand, why did the "Mustache Spirit" run so fast, it turned out that what appeared immediately after her figure was an ancient big "steamer" called "Ling", that is, there was a "Ring", big and small, at first glance, it was still a guy with broad shoulders and developed chest muscles, in fact, he was so poor that he didn't have the bottom of his pants to wear, so he could only sit on top of her, and there was a layer of "grate" with holes in the middle.

"The Ling, which has the same sound as the 'eye', is divided into two parts: the upper is the retort that penetrates the bottom, the lower is the water-receiving grate, and the middle grate has a hole through it, which can make the heat rise." Just when Mi Qiao showed the word "Ning" and carefully annotated it, Shu Kang remembered an ancient book she had read, "Hanshu • Baiguan Table", which read: "Kun Ningyan, good at ascending." Yan Shigu also said: "Those who are good at ascending." It is said that the mountain is shaped like a retort. ”

"Hehe, Yamagata, okay! The combination of the two is a bit of a 'mountain'. Shu Kang took this combination as a whole, appreciated it again, and secretly commented on it.

As a combination, "Lingling" behaved very upright from beginning to end——— in fact, they were competing up and down, "Lingling" was afraid that "Lingling" would be unhappy, and as soon as his feet slipped, he would throw him off her head, so he exerted his strength, desperately using his triangular waist to close and the bottom to thinner the waist to support the head circumference of the Ling.

The "Lingling" maintained the "peace and tranquility" on the surface, and retreated lightly.

Further down, a group of strangely shaped bronzes came on the stage one by one, and Shu Kang gradually became a little "aesthetic fatigue", thinking to himself, these two disciples are really not easy, and these "pots and pans" who are somewhat careful for more than ten years, can still remember such a complex name.

"Are they all pots? Is there anything else? "Shu Kang thinks that he has been in the kitchen for too long, and he should look at it in a different genre.

"Back to the master's words, so the realm is a 'place of open fire', and all the spirits where they are stationed are spirits that can withstand the burning of open flames. Jiaoyue replied, while retracting Ruyi's eyes, staring at the clouds again, and chanting: "The spirits of the clan are no!" ”

Mi Qiao also retracted her gesture and returned to a respectful standby state.

Seeing the two disciples and giving a serious demonstration, Shu Kang said that he was very eye-opening and exclaimed: "It seems that you are indeed serious about cultivating!" ”

"But, I've seen it all, how the hell is this door opened?" Next, I was still curious about what it looked like.

"Back to the master's words, that's because we didn't choose any spirits, since all the spirits in this line have no karma, naturally there is no need to open the door." Jiaoyue replied seriously.

"Then how can we get in?" Shu Kang then asked, feeling that these spirits of the clan are managed very much "if there is something to do, nothing to disperse", it seems that it is not a dead "shift", but a very "spiritualized" project system!

"Naturally, I asked the master to give a 'deed' first, and I can start the 'opportunity' and open the door." Mi Qiao hurriedly replied, and she couldn't let the master just feel that she could only think of asking the senior sister for everything, and ignore her existence.

"Well, what do I have to work with? I'll have to think about it. Shu Kang touched his body around, looking for something he could find, so that these "spirits of the planing clan" would have a chance to show their skills.

Unzip it open, and there are only five things inside: a mobile phone, a charging cable, and three hair accessories that you get along the way: hairpins, rules, and rules.

"Actually, what I need most now is a mobile phone charger, but I think this job is too difficult for these clan spirits to do. They don't know what 'electricity' is, let alone make high-tech products like 'chargers'. I can't count on them in this matter. "I don't know what else to arrange for these little guys, and I know that they can do the "processing project".

However, Shu Kang remembered that in the "Apple Society", there was a phase of experimentation, which was to use plant fruits to generate electricity.

According to the object of the experiment at that time, the fairy Gong Xiaotao provided several kinds of fruits, including potatoes, lemons, and apples, and then operated by Yin Chongquan, who found copper bars, zinc bars and wires at that time, and remembered that he also explained the principle to everyone at that time: "The composition of potatoes or lemons and apples to generate electricity can be realized." For example, use green and high-efficiency batteries such as potatoes, which are made from zinc, copper electrodes and boiled potato chips. Potatoes are responsible for supplying the acid needed for chemical reactions so that electrons can move from copper to zinc, and act as the two poles of the battery: copper and zinc on one side. Each potato can produce about 0.5 volts, which is about 0.2 milliamps. Why did we mention "cooked" just now, because only after the potato is cooked, will a coating be produced on the surface, this coating is the key to the potato battery, and improving the potato block coating can enhance the salt bridge capacity, so the power generated by the potato coated battery can reach ten times that of the non-potato coated battery. In other words, the power generation capacity of the potatoes after cooking is about 10 times higher than before cooking, thus extending the power supply time. ”

As a physical genius with a tendency to perfectionism, Yin Chongquan further explained the working principle in detail: "The working principle of the potato battery mainly requires two metals with opposite electrical properties, one is the anode, which is an electrode with low potential, such as zinc; The other is the cathode, which is a positively charged electrode, such as metallic copper. The acidic substances inside the potato react chemically with zinc and copper, and when electrons flow from one end to the other, the electrical energy is released. Because the metal zinc is chemically more reactive than copper, when the two metals are in acid at the same time, the zinc loses electrons, and these lost electrons are transferred along the wire to the copper sheet, forming an electric current. ”

Speaking of this, it is not satisfactory, he wrote the ion equation for everyone on the paper: "Zn loses electrons and becomes Zn 2+, and the reaction that occurs on the zinc sheet is: Zn - 2e -— Zn 2+ (oxidation reaction) H+ in the solution gets electrons on the copper sheet and becomes H 2, and the reaction that occurs on the copper sheet is: 2H + + 2e -- H2 (reduction reaction). ”

In fact, these are not the point, the focus is on the last sentence he summarized at the time: "Of course, mobile phone charging is not a problem, it depends on the amount of fruit." Scientists experimented and found that 2,380 'fruit' batteries produce enough electricity to power an iPhone. ”

"Great! There is no shortage of fruit, no shortage of metal, I have a wire, and I have utensils to 'cook', it is perfect! "The brain circuit of the book has finally come full circle, back to the matter of charging the phone, and it is completely feasible in theory!
