Tang Zheng was shocked by the scream of the king of Tibet. Turning around, he was surprised and pleased: "there is a way?"

Li Xiaotian also looked at him with burning eyes.

The king nodded: "yes, there is another way. But there is a key condition for this approach, which can't be achieved at all, so I didn't think of it in the first place. "

The king of Tibetans showed his regret.

Tang Zheng's heart sank. Just when there was a glimmer of hope, he immediately pushed people into the deep valley, rising and falling, like a roller coaster.

"What is that? If you put your ideas together, maybe it can be solved. " Tang Zheng could not hide his low mood.

Li Xiaotian can't help but grip Tang Zheng's hand and desperately want to know the answer.

"All right." "There is another thing in the ghost kingdom that can hold down my dark side," said the Tibetan king. "However, this thing has long been lost, and I don't know where it is. That's why I said there was no way. "

Tang Zheng is intrigued. Is there anything else in the ghost world that can suppress the dark side of the Tibetan king?

He has seen the magic of the bitter sea. Is there anything like it in the ghost world besides the bitter sea?

"What?" Tang Zheng asked.

"Nine dark iron." The king of Tibet could not hide his disappointment.

"What?" Tang Zheng was shocked. He thought he had heard it wrong. "Are you talking about nine hell dark iron?"

The king of Tibet looked at him in surprise. He didn't know why he responded so much. He asked, "what's the problem?"

"You say that the dark side of you can be suppressed by the dark side of Jiuyou iron?" Tang Zheng asked incredulously.

The king of Tibet nodded, "yes, don't you believe me?"

"No." Tang Zheng's mouth began to smile. He just wanted to shout, "God helps me."

Five claw Golden Dragon is trapped under the imperial city. Five claws are locked by nine hell black iron. Even five claw Golden Dragon can't break away from nine hell black iron.

It can be seen that Jiuyou dark iron is extraordinary.

Five clawed Golden Dragon once said that Jiuyou black iron is one of the best materials for forging weapons and making magic weapons. Later, Tang Zheng also had a sudden dream to try to make Jiuyou black iron into magic weapons.

However, it is easy to say and difficult to do.

His real fire can't forge Jiuyou dark iron at all, and there's no way to make magic weapons.

Since then, Jiuyou xuantie has been lying quietly in the corner of Xumi world. If the king of Tibet doesn't mention it, he will almost forget its existence.

How clever was the king of Tibet? When he saw Tang Zheng's reaction, he felt a movement in his heart and asked, "how do you know the nine hell dark iron?"

Jiuyou dark iron is a thing in the ghost world. Even people in the ghost world seldom know its existence.

How can Tang Zheng, a big living man, know the dark iron of Jiuyou?

Besides, he looks familiar.

A huge question mark appeared in the heart of the king of Tibet.

Tang Zheng said with a smile: "if you have other conditions, maybe you really can't help it, but it's really heaven's will that you mention Jiuyou xuantie. I can't find anything else, but if you want it, you will have it. "

"What?" The king of Tibetans really moved. He was still guessing the deep meaning of Tang Zheng's words, but the words told the original story directly.

He has nine dark iron!

How is this possible?

This is the first thought of the king of Tibet.

In order to suppress his dark side, he almost searched all over the ghost world, and did not see the shadow of nine you dark iron. How could he run to Tang Zheng?

"How can you have the nine dark iron?" Asked the king of Tibet.

Tang Zheng smiled mysteriously and sighed in his heart that it was really heaven's will. He almost regarded Jiuyou black iron as a useless thing, but now it has become a key thing.

"I got it under the imperial city by accident..." Tang Zheng made a simple explanation in three words and two sentences.

At last, the king of Tibet could not help but sigh: "the original nine hell dark iron has already been in the world, no wonder I can't find it in the ghost world."

The king of Tibet looked at Tang Zheng in a complicated way. Tang Zheng was not comfortable with him. He said, "what do you think I do?"

"In the dark, this is the will of heaven." "I never thought you would bring me the nine dark iron," said the Tibetan king

Tang Zheng said with a smile, "I never thought that Jiuyou dark iron has such a great effect. I only know that it is a good material for forging weapons and making magic weapons."

The king of Tibet nodded: "you are right. Nine hell dark iron is a good material for making magic weapons. I think you have tried to forge it."

The king of Tibet paused for a moment and didn't wait for Tang Zheng to answer. Then he said, "you don't have to answer. I know the answer. You must have failed. "

Tang Zheng smiled bitterly: "I'm not strong enough. I really failed. I can't refine the nine hell black iron, let alone refine the magic weapon."

"Of course you will not succeed." It's no surprise that the king of the earth's treasures like to use real fire. I don't know how many products your real fire has reached. Even if you have reached the highest six products of real fire, you can't refine nine hell dark ironTang Zheng raised his eyebrows and asked curiously, "Oh, what's the point?"

"Jiuyou dark iron is the thing of the ghost world. There is no way to refine the external flame. Only the ghost fire of the ghost world can do it."

"Ghost fire?"

Tang Zheng's heart moved, and a picture flashed in his mind. A faint blue flame floated in the air, like a flower.

He once encountered ghost fire, but in his opinion it was too weak to have his own real fire.

"Is ghost fire so powerful?" Tang Zheng asked incredulously.

The king of Tibetans nodded and said, "I know your mind. Ghost fire is not powerful. Almost the practitioners of ghost world can make ghost fire, but have you ever heard the truth that one thing falls one thing?"

Tang Zheng nodded softly as if he had thought.

"Although ghost fire is not powerful, it has a restraining effect on Jiuyou black iron. It can refine Jiuyou black iron and make it into a magic weapon." The king of Tibetans vowed.

Li Xiaotian lost his mind a little, his heart was moving, and his palm leaped up with a flame, shining with a faint blue color. This flame did not feel hot, but gave a very cold feeling.

It doesn't seem to be a fire, it's an ice.

Li Xiaotian is also a member of the ghost world. However, she has been in the ghost world for such a short time that she can easily make ghost fire. It can be seen that ghost fire is really not a rare thing in the ghost world.

Tang Zheng stared at the ghost fire intensely, and wanted to take the nine hell black iron out for experiment.

He stiffly restrained this impulse, looked at the king of Tibet, and said: "Jiuyou dark iron has been found. How can we use it to suppress your dark side? What's more, will the dark side be like in the sea of bitterness, free from the prison, and once again be a disaster to the world? "

This problem is very direct and does not worry about the king of Tibet. The king of Tibet doesn't care, because the problem of Tang Zheng points to the key.

The Tibetan's face sank slightly, and he shook his head regretfully: "it's not difficult to suppress him with Jiuyou dark iron, but if you want to suppress him all the time, and let him not get out of the prison, I I can't do it. "
