Cheng Fei can't see the difference between this ore and the fragmentary ore nearby, but he has to get it by all means in Huitian tower. There must be a reason.

Seeing that Xu Lai didn't sell, Cheng Fei asked again, "I said, old Xu, it's not that I don't want to release the mission, but I have to go back immediately. The ore should be tight. Otherwise, you can sell me some, and I'll give you double spirit stone. What do you think?"

Old Xu stopped his work and looked at Cheng Fei. Old Xu is afraid that no one can catch up with him when he is staying in the army. However, he can see that he is a new man at a glance, and Cheng Fei's accomplishments are only the Ninth level of the golden elixir. He had never seen a friar of the ninth rank of the golden elixir dare to come here in these years.

Old Xu pointed to the pile of ore and said, "look at these ores, but you can say that the price is twice the market price."

"The price is easy to say, but I won't take the fragmentary ones. I'll just take the biggest one here." Cheng Fei pointed to the biggest piece in the ore heap and said.

Old Xu glanced at the ore, frowned and said, "how do you want this one? I have many good ores here. This ore is of no use. I remember a friar gave it to me to pay for the restoration of the magic weapon. You can think about it clearly. It's a waste of spirit stone to buy this ore back. "

Cheng Fei saw that old Xu didn't seem to know the origin of the ore in front of him, so he said with a smile: "it's OK. I just want this ore. Mr. Xu, you can just ask for the price. Other things don't need to be considered."

Seeing Cheng Fei's insistence on the ore, Xu said, "this ore is just big, and it's useless as obsidian. I can't use it normally. That's better. Since you want it, the price is still the market price. Anyway, I don't think it's in the way here."

Hearing this, Cheng Fei immediately asked, "how bad this is. I just told you to calculate it at twice the market price. I'm on my word. You can see how much spirit stone this stone gets according to the market price."

"Well, I won't tell you more. Since you insist on buying this ore at twice the market price, I'll give you a real price, and 2000 spirit stones can be taken away." Old Xu did not go to weigh the weight of the ore, directly quoted a price to Cheng Fei.

Hearing this, Cheng Fei immediately took out the spirit stone from Huitian tower and handed it to Mr. Xu, saying, "here are about 3000 spirit stones. Please keep them and I will take them away."

Seeing that Cheng Fei was so generous, Xu immediately put the spirit stone in his hands and said with a smile to Cheng Fei, "look at you, you have given a thousand more spirit stones. I don't want the money for your friend to repair the sword. I'll make a friend with you. If there's a magic weapon to repair it, I'll give you a 20% discount."

Cheng Fei just nodded and put the huge ore in the Huitian tower. Zhuo Yufan, who was just beside him, took the spirit stone from old Xu and said to Cheng Fei in silence: "Cheng Fei, this ore looks useless. How can you still spend such a large price to buy it? It's not a waste of spirit stone."

Cheng Fei said with a smile: "you don't know how greedy my pet monster is. If I don't buy him more, he will be angry. OK, if Lingshi goes, there will be return. Let's go back to the inn."

Zhuo Yufan wanted to give Cheng Fei the 300 spirit stones, but Cheng Fei insisted on not wanting them. He was very rich, and Zhuo Yufan had been treating him well.

On the way back, Cheng Fei also asked Huitian tower, but he didn't answer him, which made him feel strange.

When waiting for the Inn room, Huitian tower suddenly said: "it seems that I really like this time, boy. Do you want to repair your inner armor?"

Cheng Fei immediately said: "you don't speak for half a day. I thought I made a mistake and made you angry. How did that piece of ore come from?"

"It's no wonder that old man Xu has been here all his life to help others repair magic weapons. He can't even distinguish the ore. He thought it was just a piece of obsidian that was too common to be in common, but it was more than that. "

"How can I look at it? It's obsidian. Is there something in it?" Cheng Fei asked with some doubts.

"Of course, there is nothing in the world that I can't see. The old man Xu only saw that the surface of the ore was covered with obsidian, so he thought it was just obsidian. In fact, the stone star in this ore is a rare black gold nephrite which is rare for thousands of years. Because of its characteristics, its weight is similar to that of ordinary obsidian. "

"Black gold nephrite? You mean, the ore is wrapped in black gold nephrite? My God, this is a rare treasure. Black gold nephrite is one of the best materials for inner armor. The 3000 spirit stones are really worth spending. "

"That's right. Otherwise, how could I tell you that you have to get it anyway. Your ningsha robe is also made of this black gold nephrite. However, due to the serious damage, the black gold nephrite in this ore can not be completely restored, but it is enough for you. After repairing, it should be in the middle of three yuan

Cheng Fei immediately laughs. He can't imagine that he is also a person with medium-sized Lingbao. Although it's only three yuan, the inner armor can protect his life. Even if the weak hole is strong, he may not be able to destroy it.Looking back at Cheng Fei, who is happy to bloom, he said, "it may take some time to repair the Ning Sha robe. I have to use part of your spiritual power to help you repair the magic weapon these days, so you'd better not fight with others."

Cheng Fei nodded. He had planned to go back to the imperial Seminary, and he must have taken the road back. Basically, there would be no danger.

Just back to the sky tower said to him: "the demon Dan made last time has been refined for you. I think it's time for you to break through to Yuanying. I'd better wait for you to repair the ningsha robe after you break through to Yuanying. Then the progress will be faster."

Hearing this, Cheng Fei nodded and said, "that's great. It's more than two months since I left the imperial Seminary. The three-month period given to me by the dean is about to come. If he sees me break through to Yuanying, I'm afraid it will reach the peak just from the speed of cultivation."

Cheng Fei originally wanted to let the courtyard know that he had made the best use of poison, but later he thought that it would make the Dean suspect that he was the remnant of the poison sect. After all, the identity of the yard is not easy to believe that Cheng Fei is relying on the broken soul grass to let him have the means of using poison.

Their special identity can not be exposed, it is best not to expose, and when their own strength comes up, even if others know it is already late.
