"By the way, teacher, what are the materials for making the ink core?" asked Liu Chu.

"Inkstone. Tong Zhenghai said and took out a stone as black as ink from his pocket, about the size of a palm, and the shape was as round as jade.

"Moshi, what kind of stone is this, is it an ore?" Liu Chu stepped forward curiously and touched it, it was cold and cold, and it felt a bit like a black pebble.

"Ink stone is the embodiment of a condensed entity of mineral energy, the energy in it is very pure and powerful, but it cannot be used directly, only through our hammer method to transform its internal structure, so that it becomes an ink core, and after becoming an ink core, it can be used by various Karakuri machines. Tong Zhenghai explained.

"Where did you collect this ink stone?" asked Liu Chu, it was the first time he had heard of such a magical thing.

"Moshan, inside my Karakuri City. Tong Zhenghai said.

Liu Chu nodded, but he didn't notice the look of worry in Tong Zhenghai's eyes.

The ink stone in Moshan has been mined by Karakuri City for thousands of years, and now the ink stone reserves in Moshan have long been insufficient, maybe in a few decades, or even a few years, there may not be even a single ink stone in Moshan.

This is also why, how much does Tong Zhenghai attach importance to Liu Chu, Liu Chu can use a gear box to provide huge power, so that such a huge flying machine can be lifted into the air for an hour, it is simply a miracle, if this gear box can be used well, maybe in the future, Karakuri City will no longer have to rely on ink cores, and it can also achieve the status of Karakuri overlord!

The gear box, Tong Zhenghai asked for the structural drawings from Liu Chu to study, this is indeed a very delicate gear box, more exquisite than many gear structures in their Karakuri City.

Someday, maybe this gear box will be the new way out of Karakuri!

Thinking of this, Tong Zhenghai looked at Liu Chu, who was listening carefully, and was suddenly stunned, could it be that this is the nobleman of Karakumi City?

"Teacher, what's wrong with you?" Liu Chu looked at Tong Zhenghai suspiciously.

"It's okay, it's okay, it's just something that comes to mind. Okay, then the teacher will teach you the hammer method, first teach you the first ten hammers, which should be enough for you to practice for several months. Tong Zhenghai hurriedly retracted his thoughts.

Tong Zhenghai took Liu Chu to a cliff in Hulu Mountain, where there was a stone platform and a hammer, which had obviously been prepared a long time ago.

"Look, I'll do it for you. Tong Zhenghai walked to the stone platform, picked up the hammer, the figure became ereccable, and it didn't take long to leave ten afterimages in the same place, and finally the ten afterimages returned to one, turning into a figure, and the hammer fell fiercely against the stone platform.

The stone platform was instantly torn apart, splashing in all directions at any time, and Liu Chu raised his hand to block some oncoming stones.

"Well, if you don't have the strength right, you can go down and carry a stone up by yourself in a while. Tong Zhenghai looked embarrassed, he hadn't used this hammer method for more than ten years.

Liu Chu had already seen it and didn't hear Tong Zhenghai's words. The ten-in-one hammer just now was really wonderful, Liu Chu suddenly had a bold idea, if the knife technique of "One Knife" was combined with this hammer, would it burst out with more powerful power?

Liu Chu's eyes lit up, first learn this hammer method! Then try to combine this hammer method with the knife method!

"Thank you, teacher. Liu Chu bowed.

"Well, work hard, you can live on Hulu Mountain, and as for the course sign-in, the teacher will help you get it. Tong Zhenghai gave Liu Chu a cheering gesture.

Since this day, Liu Chu has not gone down on the top of Hulu Mountain, no matter the wind and rain or the scorching sun, there will be a young figure on the top of the mountain, holding a hammer and falling one by one.

One night, the sky suddenly thundered, and Liu Chu, who was holding a hammer, looked up at the sky, thinking that there was going to be a downpour, but this did not stop him from practicing the hammer technique.

Just as he raised his hammer and was about to fall, he suddenly heard an auditory hallucination, and then a thunderbolt struck his hammer, and the whole hammer suddenly shone brightly, which was the result of thunder.

In an instant, countless thunderbolts struck at the lightning, and Liu Chu was embarrassed.

"Your uncle!

Liu Chu scolded, he heard a voice just now, there was a person who called himself Thor, who was cruising for nine days, and saw Liu Chu using a hammer, he expressed his dissatisfaction, because the hammer was his exclusive weapon, so he punished Liu Chu a little.

On the second day, Liu Chu woke up from the top of the mountain and found that he had not been struck by thunder and lightning, which made him very puzzled.

Liu Chu shook his head, got up and continued to pick up his big hammer, and began to contact the hammer method.

Spring to summer, unconsciously, Liu Chu has been on the top of Hulu Mountain for two months, on this day, Liu Chu hammer method Xiaocheng, has been able to cast a ten-in-one hammer, a hammer down, there is a thousand powers.

"Haha! It's done! Hurry up and tell the teacher, so that you can practice the next set of hammer techniques!" Liu Chu was ecstatic and ran down the mountain happily.

"Good boy, why did you go down the mountain?" Tong Zhenghai, who was enjoying the cool under the shade of the tree, raised his eyelids and glanced at Liu Chu.

"Master, I've finished practicing!Teach me the next set of hammer techniques!" Liu Chu said excitedly.

"Oh, it's done, it's been practiced, it's practiced in the first hammer method of the 10-in-1, the speed is a little slow, but it's okay. Tong Zhenghai nodded slightly, not understanding what Liu Chu meant by practice.

"No, I'm already a one-star inker!Teach me the next set of hammer techniques!I'm going to become a two-star inker!" Liu Chu explained.

"One...... A star ink master, apprentice, are you making fun of the teacher?" Tong Zhenghai was so frightened that the pu fan in his hand fell to the ground, and he got up from the chair in a hurry.

"Yes, if you don't believe Master, you see!"

Saying that, Liu Chu beat out the ten-in-one hammer method, and ten afterimages appeared in a row, and finally all the afterimages were classified as a single figure, and that figure was Liu Chu, and a hammer fell, as if it had the power of a thousand jun.

"Hiss......"

Tong Zhenghai gasped, looking at Liu Chu like a monster, he became a one-star ink maker in a month, why is this so open?

"Teacher, can you teach me the next set of hammer techniques?"

Liu Chu's eyes were hot, he found that this hammer method could also increase his strength, and he felt that he was about to break through to the seventh rank of martial arts.

Not only that, but his knife skills are also a little successful, and the fall of a hammer is similar to the fall of a knife and a knife, so for the perception of knife skills, Liu Chu can be regarded as a touch of the bypass to figure out a little.

The benefits of this hammer method are too great! When he becomes a six-star ink master, he must find a chance to obtain the follow-up hammer method!

"You little monster. ”

Tong Zhenghai glanced at Liu Chu, then took the hammer from his hand and began to perform the second set of hammer techniques, which was still ten in one, but this time the posture of each afterimage was different from before, but in the end, it was also classified as a figure, and then a hammer fell.

Although there was nothing under the hammer, Liu Chu felt the air around him vibrate! This is really terrifying!

"Teacher, I'm going to practice!" Liu Chu took the hammer back from Tong Zhenghai's hand, and then ran to the top of the mountain again.

"This kid, I don't know how long it will take to become a two-star ink maker, I'm afraid it will take at least three months this time, right?" Tong Zhenghai looked at the direction of Liu Chu's departure, if he wants to become a two-star ink person, a person with high talent, I'm afraid it will take five months, according to Liu Chu's situation, judging that he succeeded in three months, it should be about the same.

The sultry heat of summer makes people feel irritable, on the top of Hulu Mountain, a young man is shirtless and hammers against a stone, each hammer has several changes, if you are an expert, you should be able to see a lot of exquisite doorways.

Liu Chu wiped his forehead, the entire palm was instantly soaked, and there were water dripping down on it, the weather was too hot, especially on the top of the mountain, close to the sun, and the temperature was higher.

Liu Chu's eyes lit up, first learn this hammer method! Then try to combine this hammer method with the knife method!

"Thank you, teacher. Liu Chu bowed.

"Well, work hard, you can live on Hulu Mountain, and as for the course sign-in, the teacher will help you get it. Tong Zhenghai gave Liu Chu a cheering gesture.
