The laboratory and the refining factory each have two protective formations, all of which have been opened. Guards have also been added outside the factory.

Only those who prepared materials for Chen Xin were allowed to enter the interior. As for the laboratory, no one can enter, and the items can be placed outside the laboratory.

Chen Xin's father left a piece of paper with instructions for using the equipment in the laboratory.

Chen Xin looked at the instructions and familiarized himself with the laboratory, but he didn't expect to give him a lot of surprises, such as the calculator of the repair version, the machine that can make molds by entering data such as size and size, and so on.

There is also a fire used for refining weapons, which is actually a starwood divine fire, a spiritual fire of up to six grades. Although it is only a wisp of branches, it also proves that its original fire should be in the mastery of the family.

Looking at the existing materials, most of the raw materials for refining the primary refining furnace are available, but only two are not purchased because the grade is too low and there is no research value. If Duobao Dao people are in the world, they should sigh that this world is rich in products!

After Chen Xin explained the types of materials to be prepared. Just sit down quietly, he has to review the refining method in his mind first, the first refining tool is really a little nervous! It didn't take long for the preparation of the materials to come back. Chen Xin instructed him not to disturb him unless he summoned him. Then he started his first refining.

The refining method of the primary refining furnace is not too complicated, first of all, the furnace body, and the furnace body must first be hard and resistant to high temperatures. Then there are eight components made of different materials and engraved with different formations, which are installed inside the furnace body. Then the introduction of spiritual fire will do.

The furnace body and parts should be cast, and the mold has become relatively simple due to the machine, so this step should have been completed by the caster in the refining furnace with divine thoughts. At the same time, the inlay formation can ensure the accuracy and fit of the refiner. Who made Chen Xin not even have a refining furnace now, and the family's existing refining furnace is not suitable. There is no choice but to cast it first and then engrave it into the formation.

This step is to draw a formation on the part with a special liquid that has been prepared, and then burn it at a specific high temperature. Infiltrate the formation into the part. The most difficult thing in this step is to draw the formation, which can not be wrong at all, and there can be no deviation, otherwise the burned parts cannot be used, and can only be returned to the furnace from casting. When Chen Xin's realm is improving a little, after having the refining furnace, this step will be much easier. Now Chen Xin has to draw slowly little by little, thanks to Chen Xin later thought of the geometry he had learned, and made simple compasses, triangles, etc., the efficiency has improved, or I don't know how long it will take?

A month later, Chen Xin finally succeeded in refining all the parts. Once combined, you can introduce the Spiritual Fire. In this step of the Heavenly Refining True Method, there are detailed records of the splitting and elimination of various spiritual fires. Chen Xin successfully introduced the Starwood Divine Fire into the refining furnace according to the method in the True Law. He also added a large number of combustion-supporting materials to the two spiritual fires, looking at the spiritual fire that was already strong in the refining furnace, Chen Xin's mood was surging, now it is almost time to actually operate, put the prepared high-grade red iron into the refining furnace, cover the lid and put the spirit stone at the bottom to activate the formation, and wait for the result after a day.

Finally able to relax, Chen Xin took a good bath and ate again. After eating Bigu Dan for a month, the taste was almost faint, and I slept beautifully.

The next day, I came to the laboratory refreshed, with a nervous mood, first closed the refining furnace formation, carefully opened the lid, when I saw a piece of red ore like amber, I finally put my mind at ease, and succeeded! This refining furnace is Chen Xin's experimental refining one, which can be said to be a miniature version, and can only refine three catties of materials at a time. After this is successful, the full version can be officially refined. After Chen Xin put the materials in the miniature refining furnace. Another round of refining began.

Two months later, the complete refining furnace was successful, and the micro refining furnace also refined about three catties of hematite. Chen Xin put the three catties of hematite essence into the miniature refining furnace, he wanted to do an experiment, the Heavenly Refining True Law recorded that the primary refining furnace could refine up to fourth-level materials. And hematite essence is a fourth-level material, Chen Xin wants to see what materials will be produced after refining the hematite refinement. But this time, the refining time is relatively long, it takes ten days. After putting thousands of catties of hematite in the complete refining furnace. Chen Xin ended this retreat.

The first thing Chen Xin did when he left the customs was to ask someone if his parents had returned. The answer was that the two came back half a month ago, stayed only two days and left.

Chen calculated that it was the day before his birthday, and his parents wanted to celebrate his birthday, and he was still in retreat at that time.

Since his parents were not there, he had to do another thing, and after worrying about it for half a month, Chen Xin went straight to the sacrifice heaven, and in his free time, there were only two guards in the sacrifice heaven.

Chen Xin stepped forward and said to the guards that he wanted to go in and try to see if he could sacrifice to the sky once and get some exercises and treasures or something.

The guard smiled and said, "There have been countless people who have tried, all of them have failed, and after sacrificing the heavens once, the stele can no longer be made to react." ”

Chen Xin said softly and stiffly: "Just let me go in and try it! ”

Chen Xin, who has a warm personality, is still very popular in the family, and besides, this is not a big deal, the guard hesitated for a moment and agreed to let him in, Chen Xin said to the guard before going in that it might take a little long for him, try not to disturb.

The guard smiled and agreed, "Don't worry! No one has sacrificed to the sky these days, and no one usually comes here, and there are not many curious people like you!"

Chen Xin, who entered the Sacrifice Heaven, quickly laid down several anti-eavesdropping and alarm formations at the door, which were all specially learned for today, although they were not profound, but they should be able to start their effects. Then Chen Xinpan sat in the middle of the house, and after meditating for a while, he began to recite the mantra of the Divine Fighting Technique, and waited until the exit of the sentence "Please have a teacher! The black vortex appeared again, and then the Duobao Dao people descended!

Chen Xin saw that Duobao Daoist appeared, and just wanted to shout out that he had been thinking about it for a long time, so as to move the master.

Who knew that the Duobao Daoist who had just appeared, flicked his fingers.

Chen Xin felt as if he had been knocked on the door of his head by a hammer, and sat on the ground. I couldn't help but exclaim: "Oh, I haven't seen the master for a year, why did you beat me as soon as we met?"

"You don't even want your life anymore, what are you going to do!" said Duobao Daoren angrily.

Chen Xin's face was confused, "Master, what are you talking about?"

Duobao Daoist snorted: "If you hadn't summoned that merciful and generous person, changing to the other one might not have cost the origin to protect your soul. ”

"At that time, I was so panicked that my mind was blank, so many immortals, I couldn't think of a single one. Only the one I adore the most has not been forgotten in my heart! Chen Xin said in a low voice.

Duobao Dao said earnestly: "Don't be so reckless next time, usually practice more ways to deal with emergencies, lucky will not patronize you every time." ”

"It's the master, my adaptability is really not good, and I have already started to practice against it. ”

Duobao Daoist nodded: "Well, I can see your current realm, according to the standards of this world, your current realm is already in the middle of the Qi cultivation period, and you have made a lot of progress! What surprised me was that person passed on your exercises, and you actually practiced the first turn, presumably you still don't know the name of this exercise, right?"

"Yes, master. ”

"This exercise is called the 'Nine Tribulations Immortal Golden Body', don't look at it, just practice the first turn, and it will be of infinite use to you! One day you will know how lucky you are to get this exercise. The tone of Duobao Dao people actually had a little envious tone. "Tell me how you succeeded in cultivating the first turn of the Nine Tribulations Immortal Golden Body, which is known as the most difficult exercise in the Immortal Cultivation Realm?"

Chen Xin briefly talked about his experience this year.

During the period, Duobao Dao people asked a few details in detail. After listening to this, Duobao Daoist smiled a little mysteriously and said: "Your experience this year is really rich enough! I don't even know what to say about you, the Li Yuanba exercise you gave to a friend is the real basic exercise of the 'Heavenly Thunder Righteous Method', which has the effect of increasing the power of almost all exercises after being used to build the foundation." Another cultivation is Ye Gucheng's exercises, Ye Gucheng is one of the few people who quickly became a master after flying to the original realm in the illusion realm, and what he is fighting is the exercise of flying immortals outside the sky, which has a strong auxiliary and enhancing effect on the exercises of flying swords. And the exercises you choose yourself are indeed gorgeous and powerful during the foundation building period, but they are useless at all during the qi cultivation period. Luckily, you've learned the 'Nine Tribulations Immortal Golden Body', and your martial arts will be of great use!"

Chen Xin asked, "How do you use it, master?" and teach me this kind of good thing! Master!"

"I can't teach this! You have to figure it out on your own, and then you don't have to be called as a teacher in the future!"

"Why?" asked Chen Xin, puzzled.

Duobao Daoist said cautiously: "I thought that summoning me in this way would not cause harm to you, but this time I found that my divine soul still had an impact on your soul, and I didn't notice it when I wasn't injured last time, but this time because of me, the scars of your soul have a tendency to expand." Seeing that Chen Xin's mood was a little low, Duobao Daoist said again: "It will be much better when your skills are higher." Now that you can refine the refining furnace, it means that you are still very talented in refining weapons, and the basics that I can teach you are included in the 'Heavenly Refining True Method', and you yourself are learning and practicing at the same time, absorbing the refining methods of this world, plus the rich products of this world, I believe that you will definitely surpass as a teacher! Okay! I'm gone, and if I get along for a while, it will hurt you a little more. ”

Chen Xin hurriedly said: "Master is staying for a while! I am not afraid of this injury, my relatives and friends are very good to me in this world." But I always feel a little estranged, and I am always cautious in what I say and do, for fear of revealing something strange and being found out that I am not from this world. Only with the master can you let down your guard and relax. Chen Xin didn't know what to say.

Duobao Daoist said in a deep voice: "The path of cultivation is like climbing a cliff, step by step, let's cultivate hard! I believe we will really want to see you one day." "Without waiting for Chen Xin to speak, Duobao Dao people disappeared into the void.

Chen Xin was babbling and babbling in his heart, muttering in his heart how to say that he would just leave! I wanted to say more touching words, hoping to teach me some stunts! Hey! I really can't see the master again until the soul is repaired, what does the master's last sentence of 'really meet' mean? Can the master really travel here? Or can I go back when I have cultivated to a high level? I don't want to! I will go back and tell my parents that I am out of the customs, and then ask them when they will be back, and then go for a big meal, and finally be able to relax after a good night's sleep.

The next day, Chen Xin, who was refreshed, walked towards the laboratory, thinking that it would take about ten days for his parents to come back, well, the hematite essence in the small refining furnace at that time should have also been refined, and I don't know what the effect will be! When he walked to the door of the refining factory, the leader of the guards came over and said hello, and after Chen Xin returned the salute, he listened to the guards say, "Early this morning, the patriarch sent an order that since you have been out of the customs, we can relocate, our family has been upgraded to a third-level sect, and we have bought a large piece of land near the Shendu Continent, and most of our factories and workshops will be moved there." This place should have been moved half a month ago. The patriarch said that you must wait until you get out of the customs and don't disturb. So it dragged on until today. ”

Chen Xin replied: "I see, then you can start moving! But you can't enter the laboratory, you have to wait until my father comes back!"

"Okay! The patriarch has also instructed those who are not allowed to enter the laboratory. Then we'll start moving!" "The relocation of the Xiuzhen Realm is efficient, some are dismantled, some are packed into storage bags, and it doesn't take long for one of the factories in Nuoda to be emptied.

Chen Xin suddenly remembered something and almost forgot something, and hurriedly called the head of the guard who was leaving: "Captain Yang will leave some of the third-level materials for me to use for experiments." The leader of the guards handed over a storage bag to Chen Xin, and then hurried away.

Chen Xin looked at the empty factory, and thought to himself, 'This is all gone, I don't need guards as soon as I get out of the customs?' It seems that he doesn't expect much from my refining results!'

Open the formation to enter the laboratory, open the refining furnace and take out the hematite essence. Another tertiary material was added to start a new material refining experiment. Then he replaced the energy tank of the miniature refining furnace with a new spirit stone. He said to himself: "A medium-grade spirit stone a day." I don't know what can be refined! There is no record in the Heavenly Refining True Fa. ”

Chen Xinna knew that in the Duobao Dao space, there was a shortage of refining materials, and it was really difficult to obtain a large number of materials for refining. If you have a lot of effort to collect low-level materials, it is better to go to the heavenly treasure! After doing this, Chen Xin walked out of the laboratory and returned to his residence to resume his normal life. And so it passed for ten days. Tomorrow Chen Xin's parents will come back, and Chen Xin will come to the laboratory again, and this refining furnace will put hematite stone again. The miniature refining furnace had already been refined, and Chen Xin had not opened it. He wanted to open it together when his parents returned.

The next day, Chen Xin's parents returned as scheduled, and before they could get home, they were dragged to the laboratory by Chen Xin. Chen Xin's father smiled and said to Chen Xin's mother as he walked: "Okay, let's go and see our precious son first, what great things have been refined." ”

The three of them came to the laboratory, the environment in the laboratory Chen Xin's father was very familiar, as soon as he came in, the first thing he found was the refining furnace in the middle, and he said in his heart, My son really practiced a thing! Then he was jumped by the hematite essence scattered in the corner of the laboratory, and the first batch of hematite essence bought by the family was transported to the headquarters for experimental production, and it was impossible to appear here! He glanced at Chen Xin's mother, who was also shocked, and then asked Chen Xindao: "Where did these hematite essences come from?"

Chen Xin smiled proudly, walked to the refining furnace without speaking, and then slapped a set of mystical handprints on different parts of the refining furnace, activating the lid of the furnace and slowly sliding to the side, stopping when it was almost halfway. Chen Xin beckoned to his parents, motioning for the two to come over and take a look at the refining furnace, the refining furnace is about five feet high, Chen Xin's parents approached the furnace and could just see the bottom of the furnace, and saw the hematite essence at the bottom of the furnace, Chen Xin's father asked Chen Xin in a tone of disbelief: "Is the hematite essence the 、、、、 of this furnace?"

Chen Xin nodded: "You're right! Dad." This furnace is called a refining furnace, which can remove impurities from low-grade materials and refine and purify them. Some materials can be upgraded. The hematite essence in the laboratory now is refined from hematite. ”

Chen Xin's father was stunned for a moment and said first: "You're not joking with your father, are you?" Then he shook his head and said: "No! It's just a joke, and you can't get so many hematite essences! That is, what kind of refining furnace can really refine hematite stone into hematite essence." This is a great miracle, our family revitalization is hopeful!" Chen Xin's father was very excited as he touched the refining furnace, and suddenly asked Chen Xin as if he remembered something: "You just put such a magical treasure in the laboratory, and you don't even have a guard!"

Chen Xin showed an aggrieved expression, "You can't blame me for removing all the guards, okay? Besides, if you don't let you see it with your own eyes, I told you that I can turn the hematite stone into a hematite essence, do you believe it?"

Chen Xin's father was a little embarrassed and said: "I still don't believe what I have seen with my own eyes! Don't say I have heard about it! I don't blame you for this! As the old saying goes, the most dangerous place is the safest, and no one would have thought that in such a place, there would be such a heavy treasure." You said it wasn't Xiaofen. ”

Chen Xin's mother almost laughed out loud when she saw Chen Xin's father's embarrassed appearance, and hurriedly replied: "Yes, yes"

Chen Xin's father hurriedly diverted the topic: "Let's quickly put away the furnace ding! Xiaofen, you go and collect those hematite essences." Putting away the refining furnace, Chen Xin's father breathed a sigh of relief: "Chen Xin!

Chen Xin muttered in his heart, when did I say that I was going to dedicate it to the family! I didn't see that my father was quite thick-skinned. But he said, "Don't worry! It's okay, my master just wants me not to leak the refining method! But he didn't restrict the use of the tools I have refined." You can use it with confidence!"

Chen Xin's father looked at Chen Xin with emotion: "Child, since you officially cultivated, you have given your father too many surprises, Tianwutang graduated first in the double list, and brought back a large number of points so that the family has been upgraded to a third-level sect. Two body changing pills, your mother and I have passed the best period of taking, but it has also greatly improved our physical fitness! A few days ago, we have all entered the late stage of Hedan! Today's refining furnace has made me see the hope of family revitalization, you are really the lucky star of our family! Dad is really grateful to you!"

Chen Xin hurriedly said: "Dad, don't say that, there is no me without you, let alone any good fortune!"

Chen Xin's mother said on the side: "The things are finished. Let's go back and talk!"

Chen Xin's father replied: "Okay! Let's go back and talk in the secret room. "After that, I have to go out.

Chen Xin hurriedly said: "Don't be busy! There is one more thing!" As he spoke, he walked to the small refining furnace, "Mom, Dad, come and see!"

Chen Xin's parents came over, and Chen Xin's father asked, "What else is going on?"

Chen Xin replied, "There is a little surprise for you!"

Chen Xin's father put his hand on his chest and said: "There are still surprises! Your father, if I are an ordinary person, sooner or later I will be scared out of your heart attack, say! What else?"

Chen Xin smiled and said, "Dad doesn't need to be excited too early, I'm not sure if it's successful or not, I'll know later." After that, he used the Fa to open the small refining furnace, poked his head over first, and said in his heart: The time to witness the miracle has arrived. When you see the objects inside the furnace, you can relax and know that you have succeeded.

Reaching out to pick up the objects in the furnace, Chen Xin's parents looked curiously at a translucent, jelly-like object in Chen Xin's hand, emitting a faint red light, and asked at the same time, "What is it at this time?"

Chen Xin had already identified the type when he picked up the object, this thing is called Flowing Flame Gold in the Heavenly Refining True Method, and this world is called Water and Fire Jade is the material of up to the sixth grade, the treasure of refining fire attribute magic weapons, "It is Water and Fire Jade!"

Chen Xin's father snatched it up when he heard it! He carefully identified it for a long time! He muttered in his mouth: "It's really water and fire jade, it's really water and fire jade!" Could it be that Chen Xin is also refined by the refining furnace?"

Chen Xin replied: "Yes! My master told me that the refining furnace can be refined in one day, and in ten days, it can be refined in a thousand times, and a thousand refining can become treasures! I did an experiment with hematite essence, and it was really successful!"

After listening to Chen Xin's words, Chen Xin's father frowned and was silent for a long time. Chen Xin's mother couldn't help but ask anxiously: "Yongzhu, what's the matter, the child has refined such a treasure, why do you still seem to be a little unhappy!"

Chen Xin's father replied solemnly: "How could I be unhappy! What I'm worried about is that to say that the refining furnace can extract fourth-level materials is the hope of the family's rise. Once it is known to the outside world, it will cause a lot of vibration, and there will definitely be watchers, and we may be able to deal with it, but it is a big deal to give up certain interests. But once outsiders know that the refining furnace can refine the five-grade materials, then for our family, there will be a disaster of annihilation!"

Chen Xin was surprised: "Is it so serious?"

"Why not, the material into the sixth grade is not mass-produced, it is no longer a mineral, it can be called a treasure! The top sect is also not able to use the six-grade material at will, if they know that our family can mass-produce the six-grade material, waiting for us will be arrested, like a torture like a soul, after the refining furnace is fully mastered, it will be like a lack of grass. You say it's not serious!"

Chen Xin shuddered when he heard his father's words: "It's so terrifying, don't hand over the refining furnace to the family, destroy the big one, and use the small one secretly!"

"That's not necessary, I've already thought about the refining furnace, I'll bring it back to the family secret land, it's not absolutely credible and untouchable. It can refine the functions of the five-grade material, as long as the three of us know it, it must not be used until the family is not strong enough to a certain extent!By the way, do you have any secret methods for this refining furnace?" Chen Xin's father asked.

Chen Xin replied: "Of course there is! The handprint key to activating and opening the refining furnace is the best way to keep it secret! If someone who doesn't understand the trick forcibly opens it, the refining furnace refining furnace will turn into a pile of scrap iron. The secret is very complicated, and when I go back to the secret room, I will explain it to my dad slowly!"

"Alright then, this little refining furnace and water, fire and jade. Chen Xin, hurry up and put it away, I'm scared!"
