Time flies, more than a month.

Lu Chuan sat on the edge of the cliff, polishing a black wooden stick that was the thickness of a child's arm and a little bit long, and he didn't seem to notice that someone was approaching behind him.

"Little junior brother is going to exchange for ironwood, are you going to do some kind of delicate mechanism?"

"Ha, just a stick, what kind of mechanism can it be?"

Lu Chuan snorted and said, "Second Senior Brother has had a lot of free time recently, can you instruct Junior Brother on the technique of machine casting, I heard that your Tianluo umbrella can resist the bow and crossbow, how about helping me make one?"

"The talent of the little junior brother is far above that of the brother, and after a few years, he can make a better one!"

Liu Fulin's fat face stiffened, and he tightened the brass umbrella behind his back.

Lu Chuan's face was lonely, a little depressed, and said, "How can I have any talent? It would be good to live a few more years!"

"Senior brother, don't be like this, I heard that you got the codex of your predecessors, this is a great opportunity, now in just over a month, you can make so many contributions, even the master and other families have realized and retreated, who will I give up the Wumeng Instrument Hall in the future?"

Liu Fulin praised.

Lu Chuan waved his hand in a panic and said: "The second senior brother tortured me, the codex that the younger brother got was tattered, and he didn't learn much, and there are three senior brothers and senior sisters, how dare the younger brother steal a high position when he first arrives?"

"There is a way, ambition is not in old age, junior brother is still young, and the future is immeasurable, and I will rely on you to support my brother in the future!"

Liu Fulin had a straight face, patted Lu Chuan's shoulder cordially, and said meaningfully, "When I was building a mechanism for my brother recently, I couldn't figure out a few questions, can the little junior brother ...... the codex?"

"Second Senior Brother, Little Senior Brother, you are all here!"

At this moment, an indifferent voice came, but I saw that the second senior brother Zhou Bing didn't know when, standing under the ancient tree on the edge of the cliff.

"Why is the second junior brother here, I'm discussing the secret technique of the mechanism with the junior brother!"

Liu Fulin said with a smile.

Zhou Bing said lightly: "Master is out of the customs, I estimate that there will be something to find the junior brother, and the fourth senior sister is busy with official business in the back mountain, so I came to inform him, I didn't expect the second senior brother to be there, let's go back together!"

Liu Fulin was overjoyed, and rushed down the mountain regardless of it: "Master is out of the customs, okay, so you don't have to trouble the little junior brother, I'll go to his old man for advice!"

"Looks like the old madman has succeeded!"

Lu Chuan did not hide his bad feeling for the public transmission, but his eyes fell on Liu Fulin, who was in a hurry.

In other words, if anyone has broken hamstrings, if they have no emotions at all, it is a strange thing.

"It's really successful, and I'm about to ask You Lao to help test the power of the new mechanism!"

Zhou Bing tugged at the corners of his mouth, looked sideways at the cliff, and said meaningfully, "Senior brother has been here for more than a month, so he must have known his situation, right?"

"Huh?"

Lu Chuan frowned slightly.

Zhou Bing turned around and walked to the side: "You are not allowed to be in the imperial court, and you are seriously ill, the sect will not admit you, and you are arrogant, you will never be a slave to the wealthy family, if you leave the Wumeng, you will not be able to move an inch!"

Lu Chuan hurriedly followed: "Third Senior Brother won't think that if I borrow a few wooden sticks, I can go down to this cliff, right?"

"The little junior brother is very human, so he can naturally do what ordinary people can't!"

Zhou Bingtou didn't reply, and said with a smile, "I can remind you, there are bears in this mountain, but they are much more fierce than you!"

"Huh!"

Lu Chuan pursed his lips, and his gaze swept over his left foot gloomily.

"Hey!"

Zhou Bing seemed to sigh.

The mountain wind is howling, even with Lu Chuan's keen perception, it is a little uncertain.

......

"Hahaha, Lao You, how powerful is it?"

When Lu Chuan returned to the cave with Zhou Bing, he heard Gong Yitong laughing smirkedly.

Although You Cang was embarrassed, he was not annoyed, but praised him: "Yes, I didn't expect this thing to be slightly transformed, and it can threaten the three-rank martial artist, it seems that the art of the public brother has gone to the next level, and he is worthy of being a master of the organ!"

"Humph!"

Gong Yitong happened to catch a glimpse of Lu Chuan, his smile suddenly stiffened, and he said a little unnaturally, "This kid has made a lot of efforts, and the old man will not monopolize it, this is a contribution card!"

"I've seen You Lao!"

Lu Chuan took the sign casually and respectfully saluted You Cang, making the old face of Gong Tongtong even more ugly.

"Haha, I heard that you have made a lot of contributions in the past few days, which is rare!"

You Cang smiled heartily.

Lu Chuan said: "If it weren't for the seniors who did not hesitate to spend internal qi to save each other, the younger generations would have turned into dry bones!"

You Cang stroked his beard and shook his head: "This is your chance, it's a pity!"

"Hmph, it's a pity, a tuberculosis ghost who hasn't lived for a few years should study the tricks of the machine, save some miscellaneous things, and waste energy!"

Gong Yitong patted the crossbow machine beside him, and said coldly, "Although this thing is good, it is too bulky, if you can solve this problem, the old man can call the shots and grant you a condition." ”

Lu Chuan was not stunned by the surprise, and said neither humbly nor arrogantly: "What the seniors can't do, how can the juniors be?"

"Something that doesn't make a living!"

The public loses the displeasure and flicks the sleeves.

"Brother Gongloshe!"

You Cang smiled and said, "This thing came out at the right time, and the headquarters can come in handy."

Didn't you say that you want to renovate the internal organs here? If it succeeds, it will be a great credit to the headquarters!"

"Yes!"

Gongyitong's eyes were shining, and he rushed to the stone room excitedly, "Haha, the old man wants to build the headquarters as solid as gold, even if it is the Great Jin Imperial City, it can't be compared!"

"It's all gone!"

You Cang shook his head with a wry smile and prepared to leave.

"Senpai!"

Lu Chuan gritted his teeth and followed.

"You want to ask about martial arts, right?"

You Cang seemed to know Lu Chuan's purpose, waved his hand and said, "If your master knows, you won't give up." ”

Lu Chuan looked at You Cang with a disappointed face, and turned to the Internal Affairs Hall.

"Senior Brother Zhang, my contribution this time is enough, I want to exchange for the cheats of "The Great Open Tablet" and "Thirteen Horizontal Exercises"!"

"Senior Brother Lu, this can't be done!"

Senior Brother Zhang, who was in charge, smiled bitterly and pushed the contribution card back, "Elder Gong lost before he explained, and he is not allowed to exchange the cheats for you again!"

"Ahem!"

Lu Chuan's face suddenly became gloomy, he endured the discomfort in his chest, and said in a deep voice, "Then I want this Qinghong knife!"

"This one can be!"

Senior Brother Zhang looked envious, wrote a note, stuffed it into a cylinder, shook the rattle, and sent a two-foot-long wooden box from the back hall without making a cup of tea.

"Farewell!"

Lu Chuan picked up the wooden box and left.

"It's a pity!"

Senior Brother Zhang shook his head, I don't know if it was a pity that a good knife fell into the hands of a person who had no future in martial arts, or what.

......

"You have to find a way to get out, or you'll ......"

Back in the room, Lu Chuan's face was gloomy and he could drip water, and he continued to chop ironwood with a green rainbow knife.

Under this fine gold treasure knife that has reached three lines, it was several times faster before!

Weapons are divided into ten, hundred, and thousands of refining mortal soldiers, and after a thousand refinements, after forging by special techniques, one to nine natural moire will appear.

This weapon is so sharp and sturdy that it is called a Adamantite Weapon!

Further up, there is the Famous Weapon Soldier, which has special abilities.

The entire Martial Alliance branch, even if there is a strong person like You Cang, let alone an ordinary disciple!

"Soon, just a chance!"

Lu Chuan looked at the several wooden sticks of different lengths, and a flash of urgency flashed in his eyes.

If he waited a few more months, Lu Chuan estimated that it would be difficult for him to make any further progress in his martial arts, and he would only have to survive for a while.

It's a pity that he is in the branch of the Wumeng, and he secretly doesn't know how many pairs of eyes are staring, even every time he goes to the top of the cliff, he can clearly feel the strange gaze of the staring.

"Little junior brother, quickly, the teacher is going to start rebuilding the core of the organ!"

Early in the morning of the third day, Liu Fulin knocked on Lu Chuan's door and pulled him away in a hurry.

"So fast?"

Lu Chuan was shocked.

Changing the core of the mechanism is not a trivial matter, and it requires careful calculation, after all, it is composed of countless parts of the mechanism.

Even with some of the modern mechanics knowledge he provides, this is an exaggeration.

"Haha, little junior brother, you really don't hear anything outside the window!"

Liu Fulin rolled his eyes and said excitedly, "Master, his old man is a scholar of heaven and man, and in terms of the art of the organ, he should be among the top three of the Great Jin, although it is difficult to rebuild the core of the organ, but this is created by his old man, and he is naturally familiar with it!"

"Shhh

Lu Chuan couldn't help but sigh in his heart, this public transmission is really a man of action like a science madman, and he made such a big decision in just a few days.

"...... Start"

When I arrived at the construction site, I heard the rumbling of shouts from afar.

But I saw huge wooden frames, connected with ropes, lifting pieces of boulders, arranged in a specific way.

If there are modern people here, they will be stunned, those equipment that connects ropes are impressively pulleys!

These things are from Lu Chuan's handwriting, and they are also the source of large contributions!

Through this knowledge of physics that students in previous lives will have, great manpower can be saved.

Among them, the knowledge points have a wide range of applications.

Gong Tong is also worthy of being a master of the mechanism, and he was inspired by it, and after streamlining it, he added it to the bracket parts of the crossbow machine.

Not only is the rate of fire higher, but the power has not been reduced.

In this way, there was a scene that made You Cang, a three-rank internal qi realm martial artist, embarrassed to deal with it before!

And now, I don't know what kind of understanding I have in the public transport communication, but because of Youcang's joke, I really built a lot of construction and prepared to rebuild the branch organs.

Surprisingly, several branch elders actually agreed!

As for how the bus transmission was able to make so many precise calculations in such a short period of time to ensure that the organ could operate successfully after the transformation, it was none of Lu Chuan's business.

It's a pity that he was also arrested, and he was busy spinning, his feet did not touch the ground, and he cooperated with the public transport and a few senior brothers and sisters to direct the process of organ transformation.

This movement is five days.

Crunch!

On this day, when the last few critical components were placed in the core of the mechanism, there was a sudden and overwhelming screech.

"Elder, I can't hold it anymore!"

The shouts of the person who installed the parts made everyone's hearts rise to their throats.

"Think, think of a way!"

Looking at the crumbling core of the mechanism, Gong Yitong's eyes were red, and he suddenly stared at Lu Chuan, and grabbed him, "Tell me quickly, is there any way to solve it?"

"Axles!"

Lu Chuan spit out two words with difficulty.
