A quarter of an hour later.

Zhan Wuzha has already comprehended the mystery on the murals in the second stone room, originally there was only a warm thin thread in the body that was running in the Yang Gallbladder Sutra, and now there was also a warm filament in the large intestine meridian of the hand Yangming, all of which were absorbing the essence and spirit very slowly, transforming and condensing the essence and spirit into internal breath.

Suddenly, Zhan Wuzha also noticed the two contradictory feelings of "strong" and "weak" in his body, but fortunately, he was only a little tired, not as serious as last time.

"It's okay, I didn't faint this time!"

Zhan Wuzha groaned, suddenly felt hungry in his belly, and decisively swept away the food, and then found the servants of the Xia Ke Island, found the disciples of the island master, and begged for some medicinal food to nourish the body or something.

After a toss, more than an hour passed.

Zhan Wuzha finally felt that his sense of weakness was gradually subsiding, and at the same time, he also noticed that the internal breath in the Yangming large intestine meridian of his left and right hands was running.

"Why is the speed at which I cultivate this Taixuan Sutra so fast, the twenty-four stone rooms in the original book add up to nearly four months of practice, and each one has practiced for an average of four or five days......

Zhan Wuzha began to feel very strange at this time, and after pondering, he was a little sudden, and he became more and more sure of his thoughts.

However, it turned out that when Zhan Wuzha cultivated the Taixuan Sutra, the internal breath condensed by the transformation of his own essence and spirit was like a small puddle, and in the process of internal breath operation, he only guided the internal breath to carry the internal breath according to the route and direction of the meridians and acupoints contained in the mural pictures and texts, which was naturally easy and easy.

Later, before the adult Shi Zhongjian came to Xia Ke Island, he had already practiced Yan Yan Gong, and after the harmony of yin and yang, the internal force was as deep as the ocean, and he turned to the same source and more advanced Arhat Demon Suppression Divine Skill, and the internal force was even more extreme.

During this period, Shi Potian also drank Xuanbing Bihuo wine, Zhang San and Li Si's medicinal wine, and Laba porridge on Xia Ke Island, which was just to enhance the power of internal breath, and the route of its internal breath was still the Arhat Demon Divine Skill.

After that, Shi Potian once again transferred to the Taixuan Sutra, that is, to change his originally fixed route, which was no less difficult than diverting the surging rivers.

However, Zhanwuzha carried the internal breath according to the route of the meridian acupoints shown in the Taixuan Sutra, as if drawing a few deep lines on the soil next to the small puddle to guide the water out of the small puddle.

Although in the end, all rivers return to the sea, but the difficulty of the two can not be said to be the same.

Zhan Wuzha cracked the mystery of the second stone room, so that he had time to observe the things on the surface of the mural, and he had never learned any martial arts moves, so he simply learned the similar static single-frame action pose of the person in the picture according to the cat and the tiger.

"Wow!"

Zhan Wuzha was shocked, maintained the posture and movement of the person in the picture, and found that the filamentous internal breath that he had just learned was running in the large intestine meridian of the hand Yang Ming in his body, which was much more active than before, but he didn't know how much it was active.

So he was silent in his heart for dozens of times, and noticed that the speed of absorbing essence and energy and condensing into internal breath had increased several times, and the filament-like internal breath of the Yangming large intestine meridian of the left and right hands became hot, no longer warm, and the two feelings of "strong" and "very weak" came from his body at the same time.

At this discovery, Zhan Wuzha decisively retracted his posture, and then the filament in the large intestine meridian of Yangming in his hand really changed from hot to warm, which made him breathe a sigh of relief.

And in the dark, he had a feeling in his heart that if the state just now lasted for another ten seconds, either the body instinctively activated the self-protection mechanism and fainted instantly, or he would go mad and cause greater danger.

"Well, maybe the person on the mural in the first stone chamber can also speed up the efficiency of the internal breath according to the posture of holding a fan with his left hand and flying palm with his right hand."

Zhan Wuzha thought like this, took a big stride, came to the first stone room, and did a little experiment, and sure enough, it was verified that the person in the picture on the stone wall helps the internal breath to operate.

"But this consumption is too great, and it makes the body extremely weak at every turn, and it is really not groundless to be poor and rich." Zhan Wuzha secretly pondered, and found that the essence consumed when the internal breath was running was really huge, and he shook his head, planning to find some medicinal wine to enhance the internal breath.

Subsequently.

Zhan Wuzha knew that there were many prescriptions to assist in internal strength on Xia Ke Island, and asked the yellow-clothed servants on Xia Ke Island to learn that this prescription to assist in the cultivation of internal strength could indeed be watched, but it had to be approved by the two island master disciples of Long Mu, so he asked the servant to lead the way to find the island master disciples who were good at talking.

Not much.

Zhanwuzha was taken to a stone chamber that smelled of medicine, and the servant entered the stone chamber and told Zhanwuzha the islander's disciple about Zhanwuzha's request.

When the servant came out of the stone chamber, he said, "Please come in!" ”

Then, Zhan Wuzha thanked him and walked straight into the stone room.

"Mr. Zhan's erudition, I occasionally heard the master mention it, and after understanding, I was even more shocked, you tell me why this hand-cranked generator generates electricity?" A middle-aged man in a black robe with messy hair walked out with a hand-cranked generator, with two dark circles under his eyes, and shouted happily.

Zhan Wuzha looked at it, the other party's appearance was somewhat similar to the professor who studied black technology in his impression, and the black robe originally seemed to be a green robe, and he said straight to the point: "I can talk about the principle, but I came this time to ask for something." ”

"Prescriptions to assist in internal cultivation are not a problem, even if it is medicinal food and medicinal wine to assist in internal cultivation, I can find them for you." The middle-aged man in the black robe with dark circles under his eyes replied indifferently, and then said earnestly: "Mr. Zhan, please here!" ”

Zhan Wuzha was actually quite happy with the title of "Mr. Zhan" at first, but after hearing it a lot, he was a little ashamed, and he had mentioned it to the owner of Longmu Island before, but they said that looking at the world, the name of Mr. was well deserved, and then he was as relieved as he is now.

The two sat on either side of the table, where there was a hand-cranked generator with the wooden casing removed, and an electric fan with the wooden casing removed.

"Wait a minute, I'll sort out the language first!"

Zhan Wuzha pondered in his heart, a little difficult, and simply replied directly: "Its essence is to use appropriate magnetic and conductive materials to form magnetic circuits and circuits that carry out electromagnetic induction with each other, so as to generate electromagnetic power, that is, to generate current. ”

"Well, if there is something you don't understand, you can ask questions now, and I can answer them one by one."

Zhan Wuzha has a headache, after all, most of this knowledge is buried in the depths of his mind after the college entrance examination, and for various reasons, it is very difficult to do, even more difficult than that young man Shi Zhongjian.

"Ugh!"

The black-robed middle-aged man was stunned for a moment, and after a while, he arched his hand and asked, "The word conductive seems to guide electricity?" Magnetic conductivity is not a guiding magnetic force? Electromagnetic induction, I really don't understand it, please Mr. Puzzle! ”

"It can be known that the magnet, that is, the magnet, the invisible force field around the magnetite can be called the magnetic field, and it can be roughly considered that this magnetic field is composed of countless invisible thin lines, and these invisible thin lines can be regarded as magnetic inductance lines......"

Zhan Wuzha racked his brains to explain how the movement of a closed conductor to cut magnetic lines in a magnetic field produces an electric current, and the middle-aged man in the black robe also raised his doubts from time to time.

With such a question and answer, time flies, and it takes more than three hours in a blink of an eye.

During this period, because there were a lot of magnets and gold, silver, copper and iron in the stone room, Zhan Wuzha supplemented it with physical inspection, and soon the middle-aged man in the black robe roughly understood the principle, and he could also make a generator according to the principle.

And Zhan Wuzha also saw the strong strength of this middle-aged man in the black robe, the gold, silver, copper and iron in his hands, easily and casually pulled into a silk thread, and the gold, silver, copper and iron wire drawn into a coil formed by the wire, each silk thread does not touch each other, absolutely distinct.

In the end, the generator made by the middle-aged black robe chose a gold wire coil, which was not only better than the generator that Zhan Wuzha had guided and manufactured, but also made extremely fast.

We chatted for a while.

Zhan Wuzha also felt that there was nothing to say, so he brought up the matter of assisting internal strength, and the middle-aged man in black robe also kept his promise and personally went to his senior brother to ask for prescriptions, medicinal wine and pills to assist internal strength.

"Mr. Zhan, go slowly!" The black-robed middle-aged man said with a smile, and it was not difficult to hear the implication in his tone that he couldn't wait to go back to study the generator.

"Thank you! Leave! ”

Zhan Wuzha thanked him, took the prescription, and five jade bottles and two bottles of medicinal wine, as well as two wax pills, these two wax pills contained the Flame Pill and the Ninety-Nine Pill respectively, and naturally knew that this was refined by "Zhang San and Li Si".

"Use the mild one first, and then drink the medicinal wine when the internal strength is deep! Finally, the Agni Pill and the Ninety-Nine Pill! ”

Zhan Wuzha knew the use of pills and medicinal wine from the black-robed middle-aged man, his footsteps were stunned, and he thought in his heart: "I don't seem to have asked the black-robed middle-aged man what his name is!" ”

"Forget it! Just go back next time. ”

Zhan Wuzha walked to the first stone room, looked at the murals carefully to deepen his memory, and came to the second stone room, he also deepened his memory of the murals, and said in his heart: "These murals, on the surface, have a set of martial arts, but unfortunately I can't understand it, I can't understand it, I can only understand its essence, think about the route and direction of the meridians and acupoints, and practice internal force." ”

He sighed, a little bit trying to practice the superficial martial arts moves, feeling a little ashamed of his thoughts.

Come to the third stone chamber.

As soon as I stepped into it, I saw people in twos and threes chasing with light skills, each of them was extremely fast and fast, and their skills were extremely high and similar, leaving some afterimages behind them, and they formed a circle.

The distance between them has always changed slightly, the sleeves and plackets are whistling with the wind, rapid and strong, each other's breathing is very steady and powerful, talking, reasoning, telling their own understandings, and they all believe that they are right.

"The silver saddle shines on the white horse."

Zhan Wuzha saw these five words on the stone wall at a glance, and read them silently, only to see that the figure depicted on the stone wall was a horse running with its head high, and the clouds under the hooves were full of air, like a whimsical and vigorous.

"You need to watch the trend of the lines depicted on the stone wall, and then you can practice it step by step!"

Zhan Wuzha took out the jade bottle from his arms, the bottle body carved the three characters Pei Yuan Dan, and then poured out a white Pei Yuan Dan, it is said that the medicinal effect is stronger than the small pill, slightly weaker than the big pill, the medicinal power is mild, and it is most suitable for assisting rookies to cultivate internal strength.
