In a remote basement, Gu Chao began to build ultrasonic emitters.

In fact, Chapter 404 is regulated by a variable resistor. And then propagating through the ultrasonic transducer, which is really a relatively simple circuit diagram. It's easy to draw a circuit diagram, but it's a bit more troublesome to do.

The battery is easy to do, the wire is even better, just find some copper wires.

The trouble is the oscillator, as well as the ultrasonic transducer.

In order to design these kinds, Gu Chao also spent a lot of brains. If it was the previous Gu Chao, he was afraid of spending more brains, but fortunately, after passing through the harmless and non-invasive tree at this time, it can be regarded as a great improvement in the brain, and all aspects such as computing power have improved, so these can be done.

And Kong Xing'er and Xu Xuan, they stood on the side very strongly at the beginning, they really didn't believe in Gu Chao's things, they didn't understand it at all.

In the past, whether it was Gu Chao's poetry. ╔╗ It's still Gu Chao's arithmetic, they all know a little.

These two girls have a lot of self-esteem.

However, this time, they collectively felt frustrated, they didn't understand, they didn't understand it at all.

Whether it is the picture Gu Chao draws, or what Gu Chao is doing, they don't understand it at all. This makes them very skeptical of their IQ now.

Kong Xing'er shook her head: "I don't understand, what about you? You have recently taken the Yin Inner Pill to increase your wisdom." ”

"I can't see it either. Xu Xuan shook his head helplessly: "I look at Confucianism, vertical and horizontal, which have increased comprehension. But I still don't understand Gu Chao at all, it seems that it is not the knowledge of our world at all, and I don't know where Gu Chao learned it. ”

In the end, the two girls gave up collectively. They'll want to throw up if they stay here any longer.

Gu Chao is still in the process of making, and the production process is not short, mainly because of the serious lack of materials, and everything has to be made by himself. In the end, it took more than 20 days to finally make the first ultrasonic emitter. Make the first one, then make the second, the third, more and more.

The rest of the process is basically an assembly line.

A month later, Gu Chao shrugged his shoulders, as if he wanted to shrug off all his exhaustion.

Princess Xingyue asked, "Done?" Although she is much more powerful now than in the past, she also can't understand here.

"It's done. Gu Chao nodded. Now a lot of ultrasonic transmitters have been made, and they are all high-power, so it's no wonder that Tian Dan is not yin.

"Then can we start the second step now?" Princess Xingyue asked, she was now extremely interested in Gu Chao's plans, Gu Chao's plans were so wonderful.

"Nope. Still have to wait. Gu Chao said.

"What are you waiting for?" Princess Xingyue asked.

"Wait for a message, and if that news comes, we can launch it. ╔╗" Gu Chao said.

"What news are you waiting for?" Princess Xingyue asked.

"News about Prince Haowu and the Sixth Regiment. Gu Chao said.

Next, of course, I continued to wait for the news, because the ultrasonic emitter was finished, and the poison to deal with the demon beast was almost ready. Poisons are made of nine gaseous poisons, some of which can be emitted with black light in the dark, and some can be emitted with mist. Dongyao Zhenren's own medicine technology is unique in the Great Qi Empire, and he doesn't dare to call it unique in poison technology, but he is also in the top few, Gu Chao has the inheritance of Dongyao Zhenren, although the research in this area is not too deep, but in the way of using poison, it can completely explode the poison Langjun and others, and these poisons can make the Royal Beast Gate startled.

Well, these things are done, and Gu Chao is idle.

And during this time, for some reason, there was thunder in the fall, which was really weird weather.

Gu Chao also simply came to practice the fast electric knife method, after all, his fourth-order knife method fast electric knife method has not yet been completed. ╔╗

Gu Chao flew above the clouds with light skills, watching the thunder in the sky.

Thunder and lightning slammed down from the sky and slashed towards the earth.

Gu Chao is now a brain with a brain domain mutation, and his memory is much better than in the past, and he almost immediately called up the information about lightning. Ordinary lightning that zigzags and forks are called dendritic lightning. A strip of lightning is called a strip of lightning when the wind blows to both sides of the channel so that there appear to be several parallel lightning bolts. Two branches of lightning if they appear to reach the ground at the same time are called forked lightning. When lightning flashes between the yin and yang charges in the clouds, and the sky of the whole region is brightened, it is called flake lightning. Lightning that does not reach the ground, that is, lightning in the same cloud layer or between two clouds, is called intercloud lightning.

Gu Chao sat on top of the clouds, watching these lightning bolts keep coming down.

In the Tarzan School's dexterous knife technique, the first three orders are to imitate the wind, but at the beginning of the fourth order knife technique, they begin to imitate electricity, because electricity is much faster than the wind. The fourth-order knife technique is actually a turning point, a turning point from wind to electricity. At the beginning, it was wind, but if it can be completed, it is an electric attribute, and the general fourth-order sword method will not be like this, which is the special feature of the fourth-order sword method of the Taishan faction. ╔╗It's a pity that the fifth-order knife method of the Taishan faction has been lost, otherwise, it will be more powerful. In the Taishan Sect, many people who are dexterous and have roots and bones want to practice the fourth-order sword technique to the fullest, but it is quite difficult, and it is difficult to turn electricity from the wind.

But now, Gu Chao has got this opportunity.

Seeing this kind of lightning constantly splitting in the sky, Gu Chao also began to simulate the attacks of these lightnings, and at this time he found that many of the moves in the fast electric knife method will actually turn into various shapes when slightly combined, some of these states are like branch lightning, some are like ribbon lightning, some are like fork lightning, some are like sheet lightning, and some are like cloud lightning.

Gu Chao kept making strokes, and his comprehension of the fourth-order sword technique deepened by another layer.

Gu Chao's knife technique also changes from time to time, and finally found that there are only five major moves in the fast electric knife method, which are branch lightning moves, ribbon lightning moves, fork lightning moves, flake lightning moves and cloud lightning moves, of course, these five moves can be derived from a variety of different subtle moves.

After Gu Chao comprehended these five major moves, he began to meditate cross-legged, no longer wielding a knife, but quietly watching the lightning.

And just like that, time kept passing.

After a full month like this, it was already winter, and the lightning gradually dissipated, and Gu Chao's eyes returned to their peaceful appearance and woke up from the retreat. Gu Chao's retreat this time has two benefits, first, he has truly practiced the fourth-order knife method to the fullest, so that the fast electric knife method is more powerful.

Second, the liberation degree of the Thunder Emperor Sword has been increased to sixty percent, and now only the last forty percent can be liberated for the second time.

At this time, the thunder and lightning have ended, and the time has entered winter, and the cold has deepened, and the cold in the sky is getting deeper. Gu Chao flew down the clouds and fell into the princess's mansion.

"The cultivation is over?" Xu Xuan sat on a tree, as if she was doing something, and she saw Gu Chao ask.

"Yes, it's over, what's the news lately?" asked Gu Chao.

"It's Sister Xing'er who is in charge of the news, you look for her. Xu Xuan said.

"Good. Gu Chao suddenly walked into Kong Xing'er's study, Kong Xing'er was criticizing what copywriting with her eyebrows, a large pile of copywriting in front of her, seeing Gu Chao's return, Kong Xing'er habitually asked Gu Chao after the retreat, Gu Chao also responded casually, and then said: "What important news is there recently?"

"Yes. Kong Xing'er quickly pulled out a copy, Gu Chao took it and swept it, skipping his eyes one by one.

Ye Xiyu, the eldest disciple of the Yue Nu Sword Sect who ranked tenth on the Hidden Dragon List, the only woman in the top ten of the Hidden Dragon List, recently defeated a powerful elder of a silver-level sect, and the status of that elder was only slightly worse than Ding Jian. Therefore, for a while, the reputation was irritated, and you must know that this is a symbol that the younger generation can already challenge the older generation, and this message is written down, although it is useless.

The Demon Cult has become more and more active recently, and for some reason, many righteous people have died under the attack of the Demon Cult, and this news can also be remembered.

Gu Chao scanned the news all the way, and finally swept the news he was waiting for.

Prince Haowu, Prince Haowen, Ye Dongliu among the four new kings, and Mao Sui among the four new kings, these people all went to the six regiments together to feel the atmosphere of the six regiments in advance. It is true that the Sixth Regiment is a superior organization, but it is also from the Six Nations, and it is more or less necessary to give face to the Six Sides, and the top teenagers from the Six Nations countries go to the Six Regiments to have a look and open their eyes before the Six Nations are elected, this is basically a convention, a person's vision is different, the pattern is naturally different, it is said that there will be a small training within the Six Regiments for a period of time, and the group of people who return from the training of the Six Regiments will be more powerful. For a long time, many people have envied the top young people who can go to the sixth group in advance to open their eyes.

And Gu Chao's first reaction after seeing the news was that the corners of his lips raised slightly.

"The opportunity has come to implement the second step plan. Gu Chao said suddenly.

Kong Xing'er is not a stupid person, she is the military advisor of the princess's mansion, she took the information in Gu Chao's hand, and after looking at it, she also showed a clear appearance: "I see, this time, we will definitely be able to settle the country in one fell swoop and kill Princess Chengxing completely." (Your support is my biggest motivation.) )
