This tower, if it is to be exercised by high-level monks, it will be done in one go, but whether it is Zhu He or Ye Fei, they do not have that ability, and it does not require much skill to train the iron bars together, but it just consumes spiritual power and time.

Leaving Jian Ruochen behind, in fact, Zhu He also considered Jian Ruochen, after all, with Jian Ruochen's cultivation, he couldn't get in touch with the refining weapon early, and he couldn't do it.

Anyway, there is such an opportunity, and I am really not afraid of Jian Ruochen's refining of something - coarse and refined pig iron is the connection between the two ends, and there is no technical content at all.

Jian Ruochen got the refined iron for the first time, he was very excited, this iron bar was more than twice as heavy as ordinary ironware, shining with a dark luster, listening to Zhu He's introduction, this is still rough pig iron, not to mention fine iron, the real fine iron is only a hundred catties of pig iron to exercise the size of a catty.

Strange proportions, a pound of fine iron is not about weight, its size is the same as a pound of pig iron, although the weight is heavy, but it is not a hundred pounds, the complete statement should be "a hundred pounds of pig iron is exercised into a pound of fine iron".

Iron essence is said to be exercised only by monks above the Yuan Infant Period, and only the divine consciousness and spiritual power of the monks above the Yuan Infant Stage can exercise the pig iron into iron essence, and then refine it into high-quality magic weapons.

Sacrifice the spiritual fire, heat one end of the iron bar to soften, and then exercise the two iron bars that are also softened together, combine them into one, and put them in water or cool them with water spiritual power.

It's not difficult, as long as the spiritual power is enough.

Zhu He calculated, Jian Ruochen's spiritual power is enough to calcine two iron bars at the same time, and the rest of the exercise can be completed by manpower - isn't Jian Ruochen's strength very strong, the hammer head will be smashed together after two blows, and then thrown into the water to quench.

He really gave Jian Ruochen a chance, so he threw down a bunch of iron bars and went on his own, but he also devoted some of his energy to look at Jian Ruochen, and he was surprised when he saw it.

Jian Ruochen sacrificed the spiritual fire as he taught, and quickly burned the two iron bars to soften, but at this time, her spiritual power was obviously not exhausted, and the spiritual fire turned into spiritual power and pressed the two iron bars together.

Ye Fei was obviously also paying attention to Jian Ruochen, and Zhu He was generally surprised, Jian Ruochen didn't seem to have exhausted his spiritual power, put the iron bar in the cold water, and looked at the cold water to make a "snort" sound, and looked at it as if there was still strength left.

Sure enough, without waiting for the iron bars to cool down completely, as if impatient, he picked up two more iron bars and repeated the previous process, Zhu He couldn't help but look at Ye Fei, and saw that Ye Fei was also looking at him, each other's eyes were full of doubts and tacit understanding, no one made a sound, and there was not even any extra movement.

Jian Ruochen thought it was very interesting, after the previous success, she calculated her spiritual power, and felt that she could repeat it at least twice, and felt that the previous spiritual flame was too strong, and it was not necessary to have such a high temperature, nor such a big flame.

Jian Ruochen's occupational disease is to think about everything she encounters, when she used to code, she would always define several formulas by herself, but now that she sees the iron bar softening, she habitually wants to calculate how to increase the contact between the outer flame and the iron tool, so as to save spiritual power and time.

She had always believed that sharpening the knife was not wrong with chopping wood, and soon discovered that she could control the size of the flame to adjust the area of the outer flame, but the larger the outer flame, the more spiritual power it consumed, which was not suitable.

When she threw the calcined iron bars into the cold water, her movements paused, and on the surface she was looking at the iron bars that were gradually cooling in the cold water, but in fact she remembered what she had overlooked, the normal Qi cultivation layer did not have so much spiritual power, as far as Zhu He had given her the hammer for mortal calcined iron.

She didn't look up at Ye Fei and Zhu He, and she knew that her actions couldn't hide from him, so she thought about it, and felt that there was no need to hide, and it was a little too late to hide now.

Since it is displayed, it will be shown in the end, Jian Ruochen fished out the two iron bars that were refined together for the first time from the water, and indifferently considered the previous problem of the outer flame and the inner flame, this time the flame is smaller, and the unit time of spiritual power consumption is smaller, but it takes a long time overall, and it is even more inappropriate.

The remaining fire spiritual power is not enough to calcine again, Jian Ruochen raised his eyelids, and sure enough, when he saw Ye Fei and Zhu He's shocked and aggressive gaze, Jian Ruochen glanced at it, closed his eyes and sat upright, recovering his spiritual power.

The reason why the outer flame has a high temperature is that the contact surface between the combustible gas and oxygen is large, and the combustion is sufficient-only thinking of this, Jian Ruochen understood that there was a misunderstanding in his thinking, the spiritual fire does not need oxygen to maintain, naturally, the highest temperature should not be the outer flame.

Thinking about the flame of the spiritual fire again, it is clearly the brightest color of the flame center part, because the internal spiritual power of the flame is the most concentrated.

Ye Fei and Zhu He glanced at each other again, and once again saw the same doubts in each other's eyes as themselves, Jian Ruochen's five spiritual roots could not be fake, the cultivation displayed on his body was indeed the first level of Qi training, and the spiritual power consumed by the refining weapon just now was indeed far more than the first level of Qi training, and it looked almost the same as the second layer of Qi training, or even more.

Ye Fei's face sank, and he glanced at Zhu He as if he was warning, Zhu He hadn't come back to his senses yet, what he thought of was Jian Ruochen's method of cutting down the silver pine, the use of power, and the expression he unconsciously revealed, which was more confident than Ye Fei, and this simple-looking cableway.

Jian Ruochen must have a different identity before entering the Heavenly Dao Sect, Zhu He looked at Ye Fei, and then looked at Jian Ruochen, and felt that they were very similar, at some point.

But not like that, most of the time.

The two of them were like ghosts, but the movements of their hands did not stop, and an iron frame soon appeared at Zhu He's feet, and a small piece of refined iron also appeared in Ye Fei's hand, and Jian Ruochen also happened to open his eyes.

In an hour, Zhu He just used up all his spiritual power, Ye Fei only consumed half of it, and Jian Ruochen also replenished and recovered his spiritual power.

There is not much spiritual power possessed by the first layer of Qi training, but Jian Ruochen has shown a lot, and even if it is a simple layer of Qi training, it will recover in an hour without taking the elixir?

Isn't her spiritual power exhausted?

Ye Fei has never been willing to exhaust all his spiritual power, except in an absolutely safe place, such as the quiet room of the Vermilion Bird Hall, or in an absolutely dangerous situation, such as fighting with other monks or demon beasts, it is just a small layer of Jian Ruochen's qi practice, and he wants to retain a part of his spiritual power?

If she retains some of her spiritual power, will she still practice Qi at the next level?

Jian Ruochen opened his eyes, and what he saw was two pairs of staring eyes, if his psychological quality was poor, he would probably be in a cold sweat.
