"A hundred years of skill."

"This is the limit of the mundane, at least human beings have been trapped at this stage for decades."

"I guess that the key to breaking the limits of heaven and man is very likely to be here."

"Break through 100 years."

"Energy over 50."

"Maybe you can become an immortal and reach the 'Heavenly and Human Realm,'" he said.

On this day, Cao Xin was telling Chongyang Zhenren his views on the direction of his future practice.

Internal force.

This is a breakthrough.

Cao Xin and Chongyang Zhenren are more inclined to this speculation-

The key to realm breakthrough lies in internal force.

Only by breaking through the internal force can the realm jump.

But the difficulty is that this breakthrough is too difficult to break through!

Chongyang Zhenren's internal strength has not been able to go further for decades.

Cao Xin's practice of the 'Moon Technique', can occupy the internal force of others as his own, and he also cannot step over.

The pathways are different.

The exercises are different.

However, both ceilings were stuck at this step.

The difficulty of breaking through can be imagined.

"But with the help of external forces—" Cao Xin beckoned, and a long table appeared in front of him. The palm of the hand brushed over the long table, and there were bits and pieces falling and arranging.

There is a Dan furnace.

There are scales.

There is an hourglass.

There is a gauge.

Hundreds of instruments of all kinds.

It can be rudimentary, or sophisticated.

It reveals mystery and fairy spirit.

In addition—

And gold and silver.

There are also herbs.

There are also various other minerals, including coal.

Instrument.

Raw material.

Various.

Strange.

Chongyang Zhenren said, "This is, alchemy?"

"It's not."

"At least."

In the new world, this profession is called 'Divine Mechanic', and those who learn and master this profession are called 'Divine Mechanics'.

In the six years that Cao Xin has observed the five observation points of the New World night after the five stars of the black hole New World have been placed, from the 'fifth observation point in the center, the 'laboratory', including the 'alchemy room' from the 'fourth observation point in the north', there is a mention of the status of 'divine pilot'.

High.

But the difficulty is also high and intricate.

It's a 'comprehensive discipline,'

Alchemy, refining, drawing, and array, these skills are all the precursors of 'divine machine refining, and if you want to become a 'divine mechanic', you have to dabble in these skills, and even have to be proficient.

Cao Xin has a total of five constant observation points in New World.

After the five stars are constant.

There is no need to reduce the internal force, only the internal force is consumed normally, and the observation can be carried out.

The force is about one minute in a year.

At present, Cao Xin can observe for more than an hour in one breath.

These five places—

The first place, in the east, is a small courtyard for a boy who plays with insects.

The second, in the south, is the cave of the alien beast's six-eared mouse.

The third, to the west, is an island where a strong man is lurking and healing.

The fourth, in the north, is the 'Alchemy Room' in a tall tower.

The fifth, in the middle, is a laboratory in an institution.

Six years.

Cao Xin kept observing.

Even though I have been observing for more than an hour a day, it is not difficult to listen and see and learn the language of the new world.

Listening, speaking, reading, writing. ….

Cao Xin learned one after another.

In particular, the 'North,' 'Middle,' the two places—

They are clearly geographically far apart, but the language and script are the same.

include

The two masters I met on the western island also spoke the same language.

From this it can be seen that, at least among practitioners, there is a 'lingua franca' in the new world.

It's to the east.

The words spoken by the boy who played with insects and the words used were quite different from the 'lingua franca'.

At the same time, there is only one teenager in this observation point, and Cao Xin can not observe much, so he does not have enough knowledge of this language.

But the focus of his observation is not in the youth, but in the 'north,' and 'middle,' and two places.

For example, 'Divine Skill, he peeked and secretly learned from the academic laboratory at the fifth observation point of the center.

……

"When I first encountered Xianshan, I was fortunate to see an immortal leading a fairy child, using various immortal instruments to refine all kinds of immortal treasures."

"I have limited stay, limited view, and this is the only thing I can reproduce."

"But I have some notes on the process of refining treasures by immortals."

"Perhaps."

"We can open a breakthrough from here."

Cao Xin half-truthfully talked about the plan.

At the central observation point, in that laboratory, Cao Xin observed the most, not only reproducing all kinds of experimental equipment in it in equal proportions in reality, including the preparation process, key points, and the selection and proportion of raw materials, etc., all of which were recorded.

Although there is still a lack of instruments such as 'copper bells,' 'magic rulers,' 'Dharma seals,' 'hand furnaces,' 'gossip mirrors,' 'five fire red atmosphere arrays,' and so on, which contain 'transcendent elements'.

But most of these can be refined by ordinary instruments.

"With gold as the main material, adding 24 kinds of auxiliary materials such as rootless water and blue seal grass, 'pure gold,' can be prepared."

"With silver as the main material, add 22 kinds of auxiliary materials such as yellow horn and deep-sea coral, and you can prepare 'Mithril,'

"Then with 'Adamantite,' 'Mithril,' as the main material, supplemented by other ordinary materials, you can refine other instruments and equipment by yourself."

"When the equipment is complete, we can start refining the 'ritual circle, and we can hope to break through."

Cao Xin took out a scroll of notes, which contained two large boxes, recording all kinds of 'magical skills, knowledge, especially experiments) that he had learned from the New World.

[I have known an old book friend for ten years to recommend to me to chase books, @

Outside of him—

Even the grandmaster can't meet the minimum requirements of 'Divine Skill.

Not to mention anything else, the heavy threshold of internal force alone will keep all the grandmasters out of the door!

……

Rumble!

On Wanshou Island, there was a roar.

Wei Feifei looked at the mountains and was accustomed to it.

In the past year, Cao Xin and Chongyang Zhenren have opened up caves, conducted experiments again and again, and experienced explosions again and again.

It has become the norm.

She was too lazy to count.

As for Cao Xin's safety-

Every time there is an explosion, I have seen Chongyang's real person embarrassed, but I have never seen Cao Xin hurt a star.

In time.

Wei Feifei had no waves, and after a glance, he continued to practice his sword against the waves.

on the island.

In a cave at the top of the mountain.

Bang!

Chongyang Zhenren lifted the earth and stones, his clothes and shoes were torn, and the skin on his face was charred black.

After him, Cao Xin came out.

is still a beautiful woman in the turbid world, except for a little dust, there is no change.

"Only one person at a time to blow up Lao Dao!"

Chongyang Zhenren has a good temper, and seeing that Cao Xin is almost spotless, he smiled bitterly.

"I need to protect the equipment."

"Otherwise, with such a bombing method, the imperial treasury will not be able to hold it."

Cao Xin shook his head.

A whistle summons the wither.

Coo~

I don't know what to do in this withered mouth, and I can see that there is a black face all over my face, but because of Cao Xin***, I still obediently went to the side to dig a cave.

Eagle talons like iron, digging.

The wings are like steel, tamped.

Snort!

Peng Peng Peng!

Not a little while.

A brand new cave was excavated.

Then the "Nanming Xuangong" was shaken, and it rolled on the spot in the cave, and the moisture in the cave was eliminated.

"Hard work."

Cao Xin and Chongyang Zhenren were reviewing the experimental process just now, and when they saw that the cave had been dug and drove away the withering spirits, they entered the cave with Chongyang Zhenren, took out the long table, equipment, materials, etc. that had just been put away in a panic, and laid them out one by one.

Seeing Cao Xin's hand.

Chongyang Zhenren smiled: "If it weren't for your 'sleeve master's immortal art, I really can't afford to delay."

Gold and silver are good to say.

But all kinds of materials and all kinds of instruments are not so easy to get back out.

Fortunately, every time it exploded, Cao Xin took it away.

But—

"It won't work like this all the time."

"This 'Thunder Sound Flame Array, it's not easy to arrange, and it's also difficult to refine each part, so it's a pity that it's a waste of time if it's always invalidated after three or five times."

Chongyang Zhenren frowned and thought as he rearranged the instrument.

Thunder Flame Circle!

This is Cao Xin's method of solving the temperature of the flame, which he learned from the fourth observation point - the alchemy room of the Northern Tower, using common metals such as gold, silver, copper, and iron, through special proportions of mixing, to build the corresponding formation patterns, refining into corresponding modules, piecing together, and instilling internal force, which can greatly increase and flexibly regulate the flame temperature. ….

It's a beggar's version of the 'Five Flames Red Atmosphere Array'.

Win in the material is common.

But the circle is rough and unstable, and refining is not easy.

It took Cao Xin nearly a year to master the refining method.

However, in terms of stability, it is really unimpressive.

But.

Even so—

"There's no need to spend too much energy on the 'Thunder Sound Fire Circle'."

"By the time we refine this magic circle more exquisitely, we will have already prepared 'Mithril and 'Pure Gold,' and at that time, the 'Five Flames Red Atmosphere Array,' the 'Bagua Furnace,' and the 'Hand Furnace' can all be refined, and we won't need to use the thunder sound anymore

Circle of Fire,"

Cao Xin shook his head.

It is not easy to push the craftsmanship and skills of the 'Thunder Sound Fire Array' up again.

Craftsmanship aside.

This is what he stole from the New World, those people are more familiar, and none of them have been able to improve, let alone the two fake tricks of him and Chongyang Zhenren.

As for the craftsmanship.

It's also hard.

Anyway, Cao Xin has mastered it so far, and he has not made much progress. And he looks at the new world, and he is not much smarter than him, obviously this formation is like this, there is no potential, it is not worth wasting time.

While promoting the preparation of 'Pure Gold and 'Mithril', by the way, I will ponder the process and technique of refining the 'Thunder Sound Flame Array'.

It doesn't have to be dedicated.

"Then let's make do with it."

Chongyang real people were helpless for a while.

He tossed with Cao Xin for half a year, trying while groping, but the progress was faster than when Cao Xin was pondering alone, and he made a lot of progress.

However, it has not yet succeeded in preparing 'Mithril,'

It's inevitable to be anxious.

"Driven by internal forces."

"Three breaths and nine turns."

Chongyang Zhenren turned his head and talked about the technical details again, his brows furrowed: "The eleventh process of preparing Mithril should be hidden here, or there is some secret method, otherwise, it is too difficult to convert the internal force nine times in just three breaths and promote the fusion of eighteen different materials and different attributes."

"It shouldn't be that high."

Chongyang real people are immersed in it.

He said that it was difficult, and he often frowned over the years, but he had the strength to face the difficulties.

Originally.

He has been in retreat on Wanshou Island for six years, and he has reached his limit, and he has not advanced but retreated.

Despair.

Twilight breeds.

But now, although it is still difficult to study the 'magic machine's refinement, but the technical difficulties are at least so that he can see progress and progress.

The light lies ahead.

As long as you overcome one level after another, you will see the light sooner or later.

This is much better than the martial arts that can't see the way ahead.

……

After the daily review.

Chongyang Zhenren withdrew from his thoughts and looked up at Cao Xin, "When are you going to leave?"

"Just these two days."

"It's not easy to make three turns and nine turns, I can't even choke on three turns now, and staying here won't help much."

Preparation of 'Mithril, the key point of the eleventh process, if there is really a secret method, Cao Xin has to carefully observe it in the new world.

He observes for more than an hour a day at most.

Can you see the secret method?

Can you learn it after seeing it?

It's both two things. ….

It depends on luck.

If it doesn't work over there, this side must continue to study and push forward with brute force.

However, with the current progress of him and Chongyang Zhenren-

One three interest and three turns.

One three breaths and five turns.

If you want to break through this technical difficulty, it will take three or five years to work hard.

There's no need to spend it here.

"Okay."

"There are three withered communication, and communication is also convenient."

Chongyang Zhenren knew that the newlyweds had not been on Wanshou Island for a long time, but they just had a headache: "You are not here, the old way will refine 'Mithril in the future, and if it explodes again, it will be miserable."

Again.

Cao Xin's 'old and new', let Ah Xia's three sons - 'Shaolin,' 'Wudang,' Kunlun, alternately travel back and forth between Middle-earth and Wanshou Island, as a bridge between him and Chongyang Zhenren.

But they are no worse than their own Lao Tzu, speed and endurance.

Back and forth.

At least half a year.

Three small wheels fly, counting the rest, can do a letter once every three months.

But this delay is not small.

In a word.

As soon as Cao Xin left, there was a lot of trouble.

But Chongyang Zhenren did not keep it, nor did he propose to go back together, and studied these words nearby.

People grow old and become fine.

I know everything.

He only hoped that Cao Xin would return to Middle-earth, and not be unprofessional.

After all.

Cao Xin is indeed young.

But he was old.

"The old way is running out of time."

"Please pay attention."

Chongyang real people rushed to Cao Xin.

"Definitely!"

Cao Xin nodded.

Day 2.

took the bored Wei Feifei and turned back to Middle-earth.

…….
