It was already getting dark, and the occasional birdsong swept through the air.

The light circle in the backyard had lit up, and the entire courtyard was filled with this gentle light.

Since the teacher asked him to forge hundreds of pieces of black-veined steel two months ago, Ye Bai has continued to come here in this state every afternoon to forge until night.

He no longer knew how many pieces of refined iron he had tempered, except for eating, the rest had been learning to build.

He is addicted to this feeling of constantly improving himself, and likes that he is stronger step by step, and he is pleasantly surprised that although the aura is constantly consumed in the process of forging, after each recovery, the aura is not only purer but also a little more.

"Okay, little four, come over and eat. You haven't eaten for dozens of days, you must know that the combination of work and rest, starving you to death, your calf keeper is going to fight with me. ”

The teacher's joking voice sounded in his ears, and Ye Bai slowly slowed down, stopped the tools in his hand and went to the table.

Ye Bai feasted on the delicious spiritual food in front of him, replenishing his spiritual energy while soothing his spirit a lot.

"With your current level, you can already easily refine some low-level materials. Wait a minute, and start working with a few of your senior brothers to help me forge the embryo of the iron core wood. ”

Zhao Cheng nodded frequently after looking at the black-veined steel he had refined.

"Okay, teacher. I also want to help my brothers as soon as possible. Ye Bai replied.

"That's good, I still need to rush to work, but now that I have a junior and younger brother joining, it should be almost the same." Feng Ying said with a smile on the side.

Ye Bai is talented and can endure hardships, the most outrageous can study and have a flexible mind, it really doesn't give us ordinary people a way to live. Wan Ming said helplessly.

"Are you poorly talented? Whoever told you kid not to study hard all day, you know to play, and now you are under pressure. ”

Zhao Cheng patted Wan Ming's head and urged him to hurry up and deal with the roast pig.

Wan Ming also picked up the knife and cut it on the body of the hedgehog, which had already been roasted crispy and delicious, the sharp blade slashed over the body of the hedgehog, the sound of squeaking continued to sound, and the skillful knife method cut out pieces of fragrant meat pieces smoothly.

Zhao Cheng also picked up the wine that had already been prepared from the ring, and several people also ate and drank happily.

"The master didn't make any money in this job, not to mention, it's still very troublesome, why do you still take this job?" Wan Ming wondered.

"Feng Xinglie is a friend of the teacher." Zhao Cheng replied with a simple sentence, and this sentence is indeed enough.

"I haven't heard you talk about it." Wan Ming muttered.

"I have to tell you what I'm wearing, kid." Zhao Cheng looked at Wan Ming with a scolding and scolding, forcing him to quickly beg for mercy.

"Teacher, I also saw the forging of the senior brothers when I was resting during this time, and I found that every time I forged and refined to the end, there were often mistakes, resulting in the material being wasted, what is the reason for this?"

Ye Bai also asked about the questions found during this time, and Zhao Cheng replied unhurriedly: "This is because of the reason why materials such as iron core wood are required to forge this set of spirit weapon armor. ”

The heart of the tree that grows in the 100-year-old ironcore tree is the ironcore wood.

Thinking of this, Ye Bai doubted: "Is it because of the fact that it is difficult to grasp and control the heat?" ”

"Not exactly, but pretty much it." Wankong sighed.

"Iron core wood, this material is the best among low-level materials, no worse than some middle-level materials, but because it is not easy to forge and refine, few people use him to refine weapons." Zhao Cheng also explained to Ye Bai.

There is an introduction to the armor made of ironcore wood that not only has good protection, but also is very lightweight.

You must know that the weight will also affect the battle, and there are a lot of armor that weighs tens of thousands of catties. Some monks who practice the body don't have much impact, and those who don't practice can only rely on spiritual power to support it.

Thinking of this, Ye Bai thought for a moment and asked, "Isn't it true that even the teacher has an absolute grasp of refining iron heart wood?" ”

"Yes, with my years of experience, the success rate is only 6 percent, let alone your senior brothers." Zhao Cheng shook his head and said.

"Is there a substitute for something like ironwood?"

"Yes, there must be, you must know that the entire immortal cultivation realm is vast, no matter how good the iron heart wood is, it is only a low-level material, but the cost of the ice and fire essence iron that can replace him is not something we can pay."

Before Zhao Cheng could answer, Wan Ming informed him of the answer in advance.

Ye Bai nodded thoughtfully, and several people also eliminated the food in the small talk.

A few people came to his refining furnace, Zhao Cheng also threw him some iron-hearted wood, and began to teach him step by step to control the fire, if the control is not good, the material will be damaged under the conflict of attributes.

"You must know that this material is not only a conflict of properties, but also because it is extremely hard, which leads to brittleness when forged, and you must know that it is easy to break when it is rigid, which is also a reason for easy damage."

Zhao Cheng explained while teaching that more than a dozen pieces of material had been damaged by Ye Bai's injury during this time, but fortunately, this thing was cheap.

"I'll leave the method and steps to you, and the rest depends on how you control the strength and heat."

Dropping this sentence, Zhao Cheng also went to busy his own business, he was not in a hurry to forge, but recalled every detail given to him by the teacher over and over again in his mind, and carefully experienced it.

"You stupid boy is usually quite clever, why are you confused when you encounter this."

He was still thinking about the teacher's operation, and the words of the second master did sound in his mind.

"Huh? Second master, what do you say about this? Do you have a good idea? Ye Bai asked.

"According to your teacher, when the earth fire burns the iron core wood, its two properties of gold and wood conflict, and if the earth fire is not controlled well, the material will be damaged, right?"

Ye Bai nodded, and the second master said disdainfully: "You kid is really confused, you are the body of the five elements, who can be sensitive to the spiritual power of the five elements?" ”

"Except for a very few people who jump out of the Three Realms, all things in heaven and earth are not in the Five Elements, and the rest are basically within the Five Elements."

"Iron core wood is also a thing of the five elements, and the conflict of its attributes is just a matter of forging and perceiving its changes while you are forging it, and then controlling the size and strength of the earth fire with its changes."

"Alas! It has to be you, second master, why didn't I think it was so simple? ”

Ye Bai suddenly patted his head and praised the second master.

The second master mocked: "If you don't say that I am the master, you are a sun thief." ”

“……… Okay, grandson, grandson, just solve the problem. Ye Bai shrugged helplessly.

Ye Bai threw the iron core wood into the refining furnace, sank into his heart to feel the flow of spiritual power of the four five lines, and always paid attention to the changes of the iron core wood in the earth fire.

Click~

With a crisp sound, the ironcore wood unexpectedly broke apart.

He observes the broken material, thinks for a moment, and then tries again. Although the theoretical aspect is basically clear, it is still not easy in practice.

…………

When Ye Bai had just taken out the iron core wood that had been calcined and was already red, he knew that he had almost mastered the fire, and just picked up the hammer and injected spiritual power to start forging, and after a while, a familiar crisp sound sounded, and his heart instantly cooled.

"It seems that the strength still needs to be practiced." Ye Bai muttered in a low voice.

As time went on, the night outside had become dark, with the occasional chirping of a few insects. And the back hall of the Ten Thousand Refining Workshop still resounded with the sound of banging.

Bang bang~

As the last hammer fell, Ye Bai controlled the ground fire to calcinate, and with the final quenching, a piece of jet-black refined iron core wood was formed.

Ye Bai has been beating for so long, and it is rare to show a smile.

His mind just wanted to relax, he suddenly felt that the little spiritual power left in his body was absorbed, and his body longed for the nourishment of spiritual power, and he knew that he was about to break through this sense of need.

Put down the formed iron core wood, immediately took out the thousand-year-old earth milk and drank it, sat cross-legged and ran the Five Elements Wheel Method, the surrounding Five Elements spiritual power was beating and surging towards Ye Bai, Zhao Cheng and they were also aware of it, and immediately put down the work in their hands and didn't want to disturb Ye Bai.

After the spiritual power was fully supplied, he also broke through to the sixth layer of qi refining naturally.

Call~

Exhaling a breath of turbidity, Ye Bai opened his eyes and got up to find that the teacher and several senior brothers were discussing something around him.

"Congratulations, the breakthrough was successful."

"Congratulations."

Seeing that Ye Bai had broken through, everyone stepped forward to congratulate him, and he also thanked them one by one.

"The fourth didn't expect that you hadn't studied for long before you had already created a piece of refined iron core wood."

Zhao Cheng observed the iron core wood that had been refined in front of him, and was surprised by Ye Bai's talent.

Several senior brothers next to him were also amazed, they had worked hard to study for so long, and the success rate was less than thirty percent, and Ye Bai had succeeded in a piece not long after he was contacted, which was really outrageous.

"Don't boast, I'm also lucky to have the physique of the Five Elements Body, and I can better perceive the changes in the properties of the material, and I can almost achieve it with the correct control of the heat."

With Ye Bai's explanation, a few people suddenly realized, after all, it was really too demonic to be able to refine the iron heart wood not long after learning.

"Even with the help of physique, whether it is the control of the heat or the strength of tempering, if you don't grasp it right, your previous efforts will be wasted, junior brother, your talent and hard work are worthy of recognition." Senior brother Wankong is also sincerely admired.

"Yes, if you have talent and don't use it, you won't grow after all."

Zhao Cheng also admired this newly recruited little apprentice, talent aside, the refiner instead valued perseverance and toughness, which was fully reflected in the fourth child.
