Gu Yige stared at the old madman's red eyes and said, "You can't use the power of muscles to forge a vein, that's because you can't perceive the internal structure of metal, and you can't use the power of muscles to change the internal structure of metal. ”

The old madman had been immersed in his own world, and when he heard Gu Yige's words, his cloudy eyes changed in vain and began to regain his clarity.

Seeing the performance of the old madman, Gu Yige was even more sure of the problems encountered by the other party, and continued: "The alchemists in the outside world have true qi, and they can use true qi to probe the internal structure of metal. There is also fire attribute true qi in the true qi, which can be melted from the inside to change the metal structure and forge the veins. ”

"Your physical strength is neither able to detect metal structures, nor does you have the muscular power of the fire attribute, so of course you can't forge a vein. ”

The old madman listened to Gu Yige's words, his red eyes, and completely regained his clarity.

Although Gu Yige was lifted in the air by the old madman, he was calm: "In the dark metal prison, the value of soldiers is mainly reflected in the precious materials used and the exquisite design. ”

"For example, the strength-based soldier mainly uses heavy metal, and the addition on the outside of the soldier is like putting on armor to increase the weight and strength. Agile soldiers are designed to change the shape and structure of the soldiers, and use external forces such as wind pressure to increase speed. ”

"As for the more advanced attribute soldiers, it's simpler, but it uses the power of the core to urge the attribute metal. ”

"Therefore, the Dark Metal Prison, although the soldiers are divided into nine grades, has no military veins, and lacks internal veins, just like a big tree that has been hollowed out of its heart, with no outer shell, but no longer has life, and a lifeless soldier is no longer a soldier. ”

Gu Yige talked eloquently, when it came to refining, he grew up in the mine since he was a child, and the most contact was metal and refining.

Moreover, the casting technique that Su Zhu taught him at the beginning was to use the power of muscles to cast soldiers without using true qi.

It's just that the original Gu Yige could only use muscle power to cast soldiers because he couldn't practice, and the problem encountered by the old madman was that the dark metal prison had no heaven and earth aura, no true qi, and had to use muscle power to cast.

Although the reasons are different, the result is the same, and the problem of the old madman may not be solvable to others at all, but in his case, it is not a problem at all.

He knew everything about the problems of the old madman, even in his heart. Because the old madman's thoughts are what he felt in his heart.

Therefore, every time Gu Yige said a word, the old madman's eyes lit up, and in the end, after Gu Yige finished speaking, the old madman's eyes lit up with a strong brilliance. At this time, he is no longer a crazy old man, but a purgatory prison master full of powerful coercion.

"The tone is not small, these children you said know it, but how to solve it, fire attribute muscle power, don't you know that muscle power is impossible to have attributes? ”

Although the old madman's mouth was tough, the palm that grabbed Gu Yige's neck was much looser.

A playful smile appeared at the corner of Gu Yige's mouth, he knew a lot about people like the old madman who was obsessed with military training.

Because he is the same person as the old madman, and he is equally obsessed with military training.

For a person who is obsessed with military training, when he finds a difficult problem that he has been thinking about for a long time, and suddenly has the hope of unraveling, the desire in his heart is indescribable.

He should make good use of this opportunity, maybe he can resolve the current crisis, and even have greater gains.

Gu Yige is simple-hearted, and nine out of ten of his thoughts are good, and only a little bit bad. In the past, he unconsciously thought that he was using good intentions, but every time he seemed to use bad intentions.

But this time, for the sake of Tongtong and Han Yue, in order to find a way out, he took the initiative to use that little bit of bad intentions for the first time.

He's going to dig a big pit for the old madman, a pit for the First Prison, and even a big pit for the Dark Metal Prison. When he saw Metal City in the First Prison, and thought of the sight he saw in the air when he came out of the Metal Prison, he already had this idea, and now he could use the old madman to realize this idea.

Looking at the old madman, there was a seductive look in his eyes, shining brightly.

"If you haven't seen it, it doesn't mean that you don't have it, you can only say that you are lonely and weak. As he spoke, he stretched out his hands and took the arm of the old madman around his neck.

The old madman didn't care when he saw Gu Yige grabbing his arm, Gu Yige was just a fourfold martial artist with a physical body, let alone grabbing his arm, even if he stood in place and let him fight casually, he would not be hurt in the slightest.

But when Gu Yige's palm landed on his arm, the old madman's gaze froze in vain, and then he showed a surprised expression.

You must know that with the strength of his physical body as a ninefold top powerhouse, and he is one of the four major prison masters of the first prison, what kind of things have not been seen, what kind of people have not seen, and what kind of things can make him show a surprised expression, it is almost impossible.

But now he not only showed a surprised expression, but also became extremely excited after being surprised: "This, this is ......"

Gu Yige smiled and said to the old madman: "What's the matter, I said that you are lonely and weak, and you still don't believe it!"

The old madman's eyes narrowed slightly, and he had just felt a scorching power from Gu Yige's hand. Although this kind of power could not cause the slightest damage to his body, it was the scorching heat emitted by the power of his physical body.

He has practiced for most of his life, and he has seen a lot of things, and he has never heard of the muscular power of the physical body realm, which can actually carry the attributes of the five elements, which is simply impossible.

Even with these nine-fold flesh powerhouses, they could only cultivate their strength to the extreme, and it was impossible for them to make intangible attributes appear in their muscles.

What's more, the muscles of the ancient grid carry the power of the fire attribute, doesn't this mean that what I just said about using muscle power to cast military veins can come true.

So even his status and knowledge couldn't help but tremble slightly, because Gu Yige brought him too much surprise.

As the prison master of the Purgatory Prison, the old madman has been obsessed with refining soldiers all his life, he has always wanted to cast soldiers with military veins, he has an ambition, he wants to refine a kind of fleshly controlled soldiers, and he wants to use this kind of soldiers to compete with the soldiers refined by the outside world with true qi.

After the surprise, the old madman regained his composure, Gu Yige only showed this power, but there are still many unknowns whether he can forge his soldiers.

The old madman let go of his hand and threw Gu Yige to the ground: "Hmph, even if this kind of strength of yours can have some effect." But how do you perceive the mechanism inside the metal, can you hear the structure of the metal, can you see the inside of the metal?"

Gu Yige sat on the ground and looked at the old madman, since he wanted to do it, then he should do it thoroughly.

"Can you bring that bag, I'll tell you how to perceive the inner structure of the metal. Gu Yige pointed to the bag on Yu Chiming's body.

The bag on Wei Chiming's body contained his and Han Yue's soldiers, and he was now going to use the old madman's hand to get it back.

"Hmph, if you dare to trick me, I'll screw your head off. "The old madman doesn't care what the purpose of Gu Yige is, and he doesn't care whether he uses it or not, as long as he can solve the matter of casting a military vein, let alone take a bag of Wei Chiming, it doesn't matter if he unscrews Wei Chiming's head.

Gu Yige took out the metal shield from the bag, hooked it with his finger at the old madman, and flicked his five fingers in succession, landing on five different positions on the metal shield, making five metal sounds.

These five metallic sounds, some long and some short, have golden drums in unison, and have a faint sound.

Gu Yige continued to flick his fingers, landing on the metal shield continuously, the sound was high and low, and finally the sound of a dragon and tiger popped out. The long wind vibrates the forest, and the drizzle moistens things, presenting a magnificent picture of wind and rain.

The rain gradually formed a small river, which flowed slowly, trapped between the valleys and unable to run into the sea.

At this time, Gu Yige's five fingers were clenched together into fists, and he hammered on the shield with a fierce blow, and the valley around the small river actually loosened, and it seemed that as long as he came again, the valley could be chiseled into a channel, and the small river could flow freely between heaven and earth, forming a river vein.

The old madman's eyes widened, he had never known that the inside of metal could make such a sound.

Could it be that the valley forest is the internal structure of metal, and the stream is the inherent vein of metal, and as long as the obstructive rocks are chiseled, the veins can be forged.

At this moment, the old madman was so excited that he almost wanted to shout, pulling Gu Yige and leaving: "Go, follow me, let's study and study well." ”

Gu Yige smiled slightly, but broke free from the old madman's hand, the technique of vibrating and listening to the pulse was the foundation of his casting technique, in fact, he only needed to tap the metal to hear the internal structure.

But in order to shock the old madman, in order to achieve the effect, he continued to bounce, showing the internal structure of the metal one by one, and exaggeratedly presented it to the ears of the old madman, and sure enough, the old madman was shocked in one fell swoop.

But he couldn't just go with the old madman, he stretched out his hand and pointed at Han Yue and Tongtong, and said, "I can't walk alone, and I want the two of them to go together." ”

The old madman frowned, stared at Han Yue and the two and said, "Why are they your mother-in-law and dolls!"
