In the smelting room, after Yi Yunfei completed the third stage of the trial, one of the rewards he got was the same as entering the trial space, as long as his heart moved, he could enter it.

Different from Yi Yunfei's imagination, this smelting room is not the kind of blacksmith house he imagined, but it is very clean and tidy, the room is not big, the walls are snow-white, there is a futon in the middle, and there are several rows of cabinets erected against the wall around it, and there are many square-shaped metals on the cabinets, and some long-shaped jade, other than that, there is nothing else.

Picking up those metal blocks, Yi Yunfei didn't know anything either, and he couldn't tell what kind of metal these things were, some were pitch black, some were snow-white, some were golden, and the long strips of jade placed in the corner of the bookshelf were only about ten centimeters long, and he couldn't tell what the function was.

"Isn't this smelting room where you can learn alchemy?Why aren't there any words left?" Yi Yunfei looked around in surprise, and the room was clear at a glance, making sure that there were really no other items other than these things, and couldn't help but fall into deep thought.

"Could it be Jade Jane?" Although Yi Yunfei didn't know much about this world, he was also a person who had played countless online games and read countless online novels, and he was rubbing a piece of jade in his hand.

According to the plot seen in the novel, Yi Yunfei tried to put the jade on his forehead, and his mind gently touched the jade, as if the computer transmitted the general feeling, and countless information was quickly instilled into his mind.

"Sure enough!" Yi Yunfei excitedly picked up the remaining jade slips and sensed them one by one, but he didn't expect that the amount of information in these jade slips was too large, which only made him dizzy, and he ran the Xuanling Sutra cross-legged on his futon, and it took a long time to recover.

"Darkiron, Darkgold, Mithril ......" At this moment, he was already able to identify what the metal placed on the bookshelf was, although he didn't know what the specific value of these things was for the time being, but he also knew that the things given in this trial space must be extraordinary.

"Fire control seals, shaping seals, inscription seals, as well as the atlas of various materials, the atlas of various weapons, it seems that this is really just a place to learn refining weapons, to refine the weapons on the map in the last jade slip, first of all, at least with the help of earth fire, I am now a half-bucket of water cultivation, it is estimated that I can only be familiar with it for a period of time, otherwise what kind of earth fire, before I get close to estimate that I will be burned!" Yi Yunfei muttered to himself, and went out of the smelting room a little unwillingly, now he can only learn some refining techniques, and he can't smelt weapons at all, so he can only continue to carry his Guan Gong big knife and use it for a while.

This time, after ten hours in the trial space, and a lot of time spent in the smelting room, it was already noon the next day when he came out, looking at the children on the hillside behind the courtyard were divided into six groups of three talent formations to practice each other, it seemed that Li Fu wanted these children to continue to improve in actual combat.

"Although this kind of battle is much stronger than boring practice, it is still a lot worse than the real actual combat, it seems that after they improve a little, they still have to take them to the trial space, but the more people know the secrets of this trial space, the more difficult it is to keep secrets, what a headache!" Yi Yunfei sighed with a dilemma.

"Everything given by the trial space is extraordinary, let's see what wonderful effect this [Natal Life Extension Refining Body Sutra] has!" Yi Yunfei thought about another exercise obtained in the trial space, and began to test with great interest.

This [Natal Life Enhancement Body Sutra] is not like the exercises taught by Li Fu to sit cross-legged and operate the heaven and earth spirit weapon through breathing, but is divided into three postures, one posture is similar to the push-ups that Yi Yunfei has seen before, but he can only support his body with his fingers and toes, and he can't move after standing up, and he can't breathe in this state of tension of the whole body.

The second pose is a horse stride pose, but it is also required to point to the ground on tiptoe and straighten the body before exhaling.

In the last position, the whole person is completely upside down, with an index finger in each hand to support the body, so that the body cannot be straightened by any object, and then breathe in. This is one of the hardest poses.

Yi Yunfei was a little disappointed, mainly because in his impression, any magic trick should have a lot of exquisite moves, one move can defeat the strong with the weak, invincible in the world, but he didn't expect that this exercise has no moves, just three simple cultivation postures.

"Dead horses are treated as live horse doctors, let's see what the effect is first!" Yi Yunfei was not interested, and started to practice this Natal Life Refining Body Sutra from the simplest first potential.

The body is completely straight, the fingers of both hands and the toes of both feet support the body, and then adjust the breathing according to the description of the exercise, agitating the muscles in the body, if it was him before, it is estimated that he will lie on the ground in less than a minute, but now he has more than 10,000 catties of strength, this consumption is nothing to him at all.

The bones in the body made a sound like bursting beans, and a feeling of soreness and numbness appeared on every inch of muscle, as if there were tens of millions of ants crawling in the body.

Persevering until the limit of his body, when he really couldn't support it, Yi Yunfei got up and suddenly found that in just a short period of cultivation, his cultivation at the second layer of the Tongmai had actually improved a lot, and the meridians extending towards his hands and arms had actually opened up half of them in this short period of time.

"I'll go, I really didn't cheat me!" Yi Yunfei carefully checked it several times, and after confirming it, he couldn't help but scold the trial space for being perverted, this is no longer a plug-in, this is a game modifier!

This also made his enthusiasm for cultivation high, trying three different cultivation forms one by one, and when the children finally ran to the courtyard with joy, Yi Yun flew out of the last inverted cultivation posture that was not completed, and the other two postures had been cultivating for two hours each, and in these few hours of cultivation, he had already cultivated to the peak of the second layer of the Tong Mai, and he was only one trace away from being able to enter the third layer of the Tong Mai.

"Sect Master, what are you doing here?" The children asked curiously when they saw that Yi Yunfei was cultivating according to the posture of the first potential, and the sweat dripped down his body on the ground under him, which was already soaking through the ground.

"Practice!" Yi Yunfei let out a long exhalation, turned over his body, and didn't care about the dust on the ground, so he sat on the ground and chatted with the children.

"What kind of skill is this, it looks so tiring, even a person as powerful as the sect master sweats so much!" was a little girl who spoke, her name was Erya, and she was the youngest daughter of a family close to the foot of this mountain.

"Yes, are you afraid of being tired?" Yi Yunfei was in a good mood and asked a group of children.

"Don't be afraid of being tired, we have to work hard to cultivate, and in the future, we will protect the sect like the sect master!" the children said in unison.

Yi Yunfei nodded at Li Fu with satisfaction, it seemed that his ideological and political education work had achieved initial results, a flash of inspiration flashed in his mind, looking at the enthusiastic expressions of the children, he suddenly thought that he didn't dare to take them into the trial space, but it was always okay to teach them part of this [Natal Life Refining Body Sutra].

Thinking of this, Yi Yunfei excitedly said to the children: "Do you want to practice the same exercises as me and become as powerful as me?"

"Yes!" the children shouted excitedly.

"Okay, then I'll teach you a set of exercises tomorrow that are very tiring to practice, but they will become very strong, okay!"

"Okay!" the children clapped their hands happily and jumped up, and under Li Fu's arrangement, they left the yard happily, chattering excitedly, and rushing towards their respective homes.

"Ah Hong, the exercises you taught them were taught to you by that immortal elder, right? wouldn't such an arbitrary transmission of the exercises cause the immortal elder's displeasure?" Li Fu watched the children walk away, and said to Yi Yunfei with some caution.

"It doesn't matter, this exercise is indeed much more powerful than those rotten street exercises in the sect, but for that person, it's not a big deal!" Yi Yunfei smiled secretly in his heart, and explained seriously.

"Exercises are the foundation of a sect, although the exercises of our sect are just ordinary exercises, or even exercises that are not in the product, but it was also when your grandfather and I spent a lot of effort to learn from the Mengjiao Sect. These children are not yet firm in their minds, if they encounter someone who asks them and leaks the exercises, it will have too much impact on the sect, so let them swear a blood oath!" Li Fu said cautiously again.

"Is there still a grade in the exercises?Is this kind of thing really useful?" Yi Yunfei asked two questions in a row with some surprise.

"How can there be no grades, according to the length of the cultivation path that the cultivator can support the practitioner take, as well as the speed of the cultivation method, the exercises are divided into three major grades: human, earth, and heaven, and each of these three major grades is divided into nine sub-grades. As for the human-level exercises, only the sects above the fifth level have them, and further up, I don't know what kind of forces can have them, but the heaven-level exercises, I estimate that even if they are first-level sects, it is impossible to have many!" Li Fu shook his head and explained the level of the exercises to Yi Yunfei in detail.

"As for the blood oath you said, don't underestimate him, and never make a blood oath easily, there is a providence in the underworld, if you really have to make a blood oath one day, you will naturally be able to sense the existence of heaven's will, if you break the oath, there is absolutely no reason to survive!" After a pause, Li Fu said to Yi Yunfei very seriously.

"Yes, I know! Then do what Grandpa Fu said!" Yi Yunfei's heart trembled, he had traveled from the earth to this place, and he had seen too many magics, and the set of cold and unscrupulous atheism in his heart before had long been dissipating, and at this moment, seeing that Li Fu said it so solemnly, he also believed in the existence of the blood oath, and nodded seriously.

Reaching the Tongmai realm, the absorption of heaven and earth aura is already very fast, and it doesn't matter if Li Fu and Yi Yunfei don't eat for a few days, but looking at Ruoxi's busy and expectant eyes, both of them still ate a little before they went back to their rooms to rest.

As soon as he lay down, Yi Yunfei suddenly felt the flow of countless violent breaths in the air around him, his heart jumped, and his divine sense quickly dispersed, and now his divine sense could extend to the outside of the courtyard wall, and the four corners of the courtyard stood in each of these people, holding a talisman that emitted golden light in his hand, constantly swiping in the air, and gently chanting inexplicable incantations in his mouth.

"Isn't it embarrassing for the four old things of the Backing Mountain Sect to use such unsightly methods?" Yi Yunfei shouted violently, and his voice was like rolling thunder, constantly echoing around this mountainside.
