The old man refused very simply, and Simon had no choice but to continue talking about the dark abyss secret technique.

"Are there any special restrictions on this dark abyss secret technique?" Simon asked.

"It has no special restrictions." The old man said.

"Old ghost, tell the truth, don't try to trick him. He is my **** of wealth. If you trick him, he won't look for me again in the future. And this kid is a real rich man. If you lied to him now, it's the same. You will cut off your fortune." Lao Yiqi said with a sullen face.

The old man frowned.

"Don't think I don't know what's in it, if you don't say it, then I'll say it." Old Iggy hummed.

The old man's face sank, "This dark abyss secret technique has no restrictions, but it has high requirements on the caster."

"any request."

"The most important thing is that the magical energy content of the shadow system is at least the level of the knight commander, otherwise it will not be able to support the casting of the dark abyss secret technique."

"That is to say, the basis for the dark abyss secret technique is the shadow magic energy content of the knight commander level. This does not include maintaining the dark abyss and casting other shadow magic." Simon was stunned and asked.

The old man nodded expressionlessly: "The maintenance of the dark abyss consumes a lot of mana, the mana content of the middle knight commander can last for three minutes, the high knight commander can last for ten minutes, and the top knight commander can last for half an hour to half an hour. within an hour."

Simon frowned even more, and he immediately realized the problem with the old man's words.

"You are talking about the maintenance time. If someone destroys it internally or externally, will this time be greatly shortened." Simon asked.

The old man's face turned even darker, and nodded expressionlessly: "If the dark abyss is damaged by impact, the maintenance time will be greatly reduced, and the interior of the dark abyss is very hard, and it is difficult to destroy the same level, but the outside is easily broken. "

When he said this, the value of the dark abyss secret technique in Simon's heart was greatly reduced.

"This dark abyss secret technique is very demanding, but it is also a means of fighting the enemy. If you sell it, what do you need." Simon said.

Although the dark abyss secret technique is extremely demanding, it cannot be said that it is not strong. It can only be said that he is the means of a high-end knight. Although Simon may not be able to fully perform the dark abyss secret technique at this stage, it does not mean that he cannot use it in the future.

"I have the extraordinary resources that I need. If you have them, the price can be cheap. If you don't have them, then change to other extraordinary resources, but they must be high-level resources." The old man said.

"Can."

The old man reported the extraordinary resources he wanted, and Simon only had a part in his hands. Simon thought for a while and said, "I only have a small part of the extraordinary resources I said."

"I want this small part, and now discuss the types and quantities of the remaining high-level extraordinary resources."

"The crystal of origin, do you want it?"

"The crystal of origin? Do you have the crystal of origin?" The old man was surprised.

"Yes, I have both the Origin Crystal and the Origin Magic Ore. If you want, I want to pick up the Origin Crystal and trade it."

"Of course no problem." The old man agreed immediately.

"Okay, the size of my crystal of origin is based on the road sign pass, and then you make a price." Simon said.

The old man was lost in thought, the crystal of origin was not easy to estimate, and he was thinking about the price.

Three minutes later, the old man quoted a price: "Six crystals of origin."

"Six crystals of origin? You are crazy, old ghost. The dark abyss is so restricted, you still dare to ask for six crystals of origin? I think two are good." Old Iki said immediately.

"You know what, it's a domain secret technique, and it can play a huge role in the battle of the great knight commander. I can kill the great knight commander with this secret technique at the knight commander level. Can't I prove it? Is it worth it?"

"Don't think I don't know, the reason why you can kill the Great Knight Commander is because of the Dark Worm contract, you summoned the Dark Worm's stomach to kill the other party.

You can bind the Grand Knight for a while at most and cannot kill the opponent. "Old Iggy mercilessly exposed the old man's lies.

The old man's face was very ugly, and he just muttered: "If it's just two crystals of origin, then I won't sell it."

"It's fine if you don't sell it, I'll go find someone elsewhere." Old Yiji said stubbornly.

The old man stared at the boss, wishing he could kill him with his eyes.

Not to be outdone, old Iggy stared back.

Simon glanced at Old Iggy, knowing that he took a rake, that is to say, the higher the selling price, the more he rake. It's not bad that he didn't raise the price, and he even helped haggle the price. At this moment, Simon felt that he was quite reliable.

In fact, old Iggy also has his own ideas, but he intends to cooperate with Simon for a long time, so he must show his ability.

"Then go find someone else." The old man was stubborn enough to disagree.

"Hey, I really thought my secret technique was unique. Come on, hurry up and leave." Old Iggy waved his hand impatiently.

"In business, it's normal to bargain. Old man, your dark abyss secret technique is indeed more than six crystals of origin. If you insist, our business will be yellow," Simon said.

"But this old thing is too cruel. The value of my dark abyss secret technique is definitely more than two crystals of origin." The old man said.

"I'm not talking nonsense. If you are willing to sell the three crystals of origin, I will accept them. If you don't want to, I will not force you." Simon also offered his own low price.

The old man thought for a minute, then nodded: "Then the three crystals of origin, do you want to trade now?"

"I'm in the wilderness now, and the crystals of origin are all at home. It can't be traded now, but we can sign the oath formation and pick up the crystals of origin to trade with you as soon as I get home," Simon said.

"Okay." The old man didn't say anything.

"Do you want other shadow system secret arts and extraordinary resources?"

"Of course, as long as I see it, I want it." Simon said richly.

The old man was a little excited. He took out all his shadow system secret techniques. There were thirteen kinds of them, strong and weak. Most of Simon didn't have them and wanted them all.

"I want all of these nine shadow secret techniques. What's the price?"

"Is there still a crystal of origin settlement?"

"right."

"Two crystals of origin~lightnovelpub.net~ are a bit expensive, but one is about the same."

"That's one piece."

"I still have the extraordinary resources of the shadow system, you absolutely need it." The old man said.

Simon became curious.

He took out a black box, which contained a crystal bottle, which contained a small bottle of pitch-black liquid, and he took it out very solemnly.

"This is the shadow real body potion."

"Shadow real body? Is it really the shadow real body potion?" Simon was quite surprised. He had heard of the shadow real body potion. This is the magic potion that shadow superhumans dream of.

The shadow body potion can allow practitioners to obtain the body of shadow. Simply put, it can make the body shadow, and it has extremely powerful effects whether it is stealth or combat.

He had been looking for a magic potion for the real body of the shadow, but there was no news, and there was no such potion in the mason guild, but he did not expect to encounter it today.
