"Oh......"

Fang Rin pondered with heavy eyebrows.

To be honest, Zhang Feng's condition is not too tempting for him.

Because the effect of the corpse crystal and the evolution liquid is the same for him, and even if the evolution liquid only counts the cost, the cost is higher than the corpse crystal, because the corpse crystal itself is one of the materials of the evolution liquid and is the energy source of the evolution liquid.

But when I think about the problem, I don't think so.

Devouring corpse crystals, this is a secret that belongs to him alone, and if he doesn't want to expose it, he needs to cover it up.

And a channel where he could buy the Evolution Liquid at a low price really helped him hide his secrets.

But then again, a channel to cover up his secrets allowed him to break into the beast cave and protect Zhang Dawei, and he was not too satisfied.

Because he didn't get any real benefits.

On the side, Zhang Feng saw Fang Rin frowning and thinking, as if he was not too satisfied with this condition, and he couldn't help but be dissatisfied in his heart.

This condition is already his bottom line.

He never likes to beat around the bush when he does things, so when he talks about conditions, he is sincere, and he always directly says what he thinks.

"Fang Rin, you should know! The evolution liquid outside, one for three corpse crystals, and one for two corpse crystals for the military in Towering City, because they are the military, and the purchase volume is huge, so they have this discount, and for you, I will give you the price of one and a half corpse crystals and a bottle of evolution liquid, which is definitely the real cost price, and even I have saved you the labor cost and other expenses, only the material cost is calculated. As long as you don't buy in large quantities to resell, I can give it to you, an evolutionary needs at least more than fifty copies of evolution liquid to evolve to the peak of the red level one star, and I believe that the evolution liquid required for more than two stars will soar by geometric multiples, this price can definitely save you unimaginable huge wealth, corpse crystals are resources, these resources saved, you can go further and faster on the road of evolution. ”

Zhang Feng said sincerely.

Fang Rin also nodded.

He recognized Zhang Feng's words very much, from the very beginning, he knew that on the road of evolution, the further back he went, the more energy he needed, and Zhang Feng's condition was impeccable in anyone's opinion.

But...... He is not among them.

"So be it!"

Fang Rin opened his mouth and said: "I don't need you to sell the evolution liquid to me at cost price, just give it to me at the same price as the military of Majestic City, and add one more condition, we will cooperate for a long time, every time you open the Thousand Heavy Building, I want you to do your best to buy the Spirit Yun Crystal in the name of the military, and then transfer it to me, and even you need to use the relationship between the military of Majestic City and Li Jiang, you can cooperate with the three parties, you can collect as much as you can, and I will reimburse you for how much money you use to buy it." ”

"Spirit Crystal?"

Zhang Feng was stunned for a moment, he couldn't imagine that Fang Rin didn't want the cost-price evolution liquid, but instead asked for the Spirit Essence Crystal of the Thousand Ice Skeleton Building.

As far as he knew, the output of this Spirit Essence Crystal was extremely small, two on each floor of the Thousand Heavy Building, and the effect was similar to that of the Evolution Liquid.

Fang Rin actually gave up the huge benefit of the evolution liquid for the sake of this little Spirit Crystal, which seemed a bit incredible.

Could it be ...... This spirit crystal may have other effects, and it is worth a lot of money?

Zhang Feng suddenly had such an idea in his heart.

"Fang Rin, I know you should have a Spirit Yun Crystal on you, can you let me see what this thing looks like? It must be extraordinary to be able to make you value it so much! ”

Zhang Feng had only heard of his name, but had never seen the real thing.

In other words, at present, within the scope of the Ice Skeleton Building, only Fang Rin and Wang Hui have seen the real thing.

"Yes!"

Without the slightest hesitation, Fang Rin took out a spirit essence crystal and placed it on the table.

Suddenly, Hua Mao, Zhang Feng, A Ning and Ah Huo all looked at this blue spar.

Zhang Feng took it in his hand and looked at it carefully, but he couldn't see anything, while Fang Rin explained: "The energy contained in this Spirit Essence Crystal is equivalent to the corpse crystal of a one-star peak red-eyed zombie, about three to five ordinary corpse crystals, and the equivalent evolution liquid should also be three to five parts." ”

"What is so special about this Spirit Crystal that makes you so interested in it? Even at the expense of the great benefits I promised you. ”

Zhang Feng asked.

This Spirit Essence Crystal was just one for three to five parts of the Evolution Liquid, this little bit of small profit, he didn't believe that Fang Rin couldn't even make such a simple calculation.

Fang Rin smiled lightly.

"To be honest, I don't know what is special about this spirit crystal in addition to absorbing energy, but I feel that the spirit crystal is easier to use, because it is produced by Qianzhonglou, to put it mildly, the evolution liquid is a human product, and the Lingyun crystal is produced by Qianzhonglou, compared with the two, I believe in Qianzhonglou more, who calls it so mysterious? So, I want to collect a lot. ”

"I see!"

Zhang Feng looked suddenly enlightened and did not continue to ask.

And Fang Rin didn't say anything more.

Fang Rin knew very well that his explanation was like a fart to others, and if Zhang Feng believed it, he would be a fool.

However, this is indeed his truth.

When he was in the Thousand Towers, he had just obtained the Spirit Crystal, and he really just regarded it as an ordinary thing similar to the Evolution Liquid.

But when I think about it carefully, I feel that it is wrong.

Just imagine, every level of the Qianzhong Building is very precious, why, just this spirit crystal, the value is extremely low?

If he now enters the second floor of the Thousand Ice Skeleton Building with the strength of a red-level two-star and desperately brushes the corpse crystals for ten days, he can definitely brush tens of thousands of corpse crystals, and what about the rewards for clearing the customs? There are only two spirit crystals.

Converted, it's only six to ten ordinary corpse crystals.

Is this normal?

It was precisely because it was abnormal, so Fang Rin felt that this thing must have other uses, but they didn't know it yet.

There are a thousand floors in a thousand buildings, and what about them? It's just the fifth floor.

How many unknown secrets there are in it, no one knows at all.

He also took a fancy to Zhang Feng's ability and courage, as well as ambition, and felt that he was a character, so he proposed this cooperation, originally he wanted to find Qin Xue, but when he thought that there was a Lin clone on top of Qin Xue, it was obvious that Qin Xue couldn't be the master in many aspects, so he gave up.

Zhang Feng is obviously a good partner to work with.

"Since you want to change this condition, of course I am willing, rest assured, every time I open the Thousand Ice Skeleton Building in the future, I will do my best to collect Spirit Yun Crystals for you, then our cooperation will be considered a deal."

Zhang Feng promised.

"Deal!"

Fang Rin also replied with a smile.
