The birth of an orange skill book required the consumption of 27 white skill books, and Chen Mo spent another eighteen skeletons to summon two groups of undead corpses.

After the preparation, Chen Mo immediately threw the three blue skill books into the material column, but this time, the content in the translucent floating window in front of him had some changes!

…… You have placed [Undead Blue]*3!

【Formula ...... being tested】

[Detected to be three pieces of the same material, your talent has played an effect, this synthesis does not need to master the recipe!] 】

[Start this synthesis quality inspection ......]

[The quality of this synthesis is medium quality, and you need to add an additional special material - Dark Crystal: Rare]

……

"The orange skill book belongs to the middle and third grade, and it's really not so simple to synthesize, but it's a rare-grade dark crystal, this material seems to be able to be dropped by most elite monsters, and it should be available in the shopping street."

Thinking of this, Chen Mo went out again and ran to the commercial street.

After a little wandering, he found a stall selling some synthetic materials.

"Young man, what materials do you want, come and see."

Seeing that Chen Mo was searching, the uncle who set up the stall asked enthusiastically.

"I want a rare grade dark crystal, I wonder if you sell it here?"

"In terms of rare-grade materials, I still have a relatively complete range here, you see that they are all rare-grade over there, and that black stone should be a dark spar." With the uncle's finger, Chen Mo saw the dark spar from the dazzling pile of materials.

At the same time, Chen Mo subconsciously looked at a piece of material area next to him, and he saw a black and purer gem, "There are also rare dark source stones, great!" ”

"Synthesizing a fourth-grade orange skill book requires consuming a fourth-grade rare dark crystal, and synthesizing a fifth-grade yellow skill book should consume a fifth-grade rare dark source stone, since it comes out, it's better to get it all at once."

Chen Mo calculated the amount, and his remaining skeleton summoning should be enough to synthesize a fifth-rank yellow skill, so he needed to prepare three rare-grade dark crystals to synthesize three fourth-rank orange skills, and then prepare an additional fifth-rank rare dark source stone.

"The amount of synthesis skills is so much, I still have a dark staff to synthesize, they are all of the same origin, and it is estimated that the material request is the same, it should be enough to buy twice the amount back......"

"Uncle, I want two Dark Source Stones and six Dark Crystals, how much do you think it costs in total?"

"The market price of rare materials is 5,000, and the market price of rare materials is 1,000, a total of 16,000."

"It's too expensive, eight thousand."

"Good guy, young man, you cut my major artery directly with this knife, how can you cut half of it directly?"

"Then I'll add a few more, nine thousand."

"To tell you the truth, there is no thirteen thousand that can't come."

"Ten thousand!"

"Ten thousand twelve!"

"In case, if it doesn't work, I'll leave, and that's all I have in my bank card." After Chen Mo finished speaking, he was about to turn around and leave.

"Little brother, I really convinced you, okay, this time I will sell it to you at a loss, if you have any good things in the future, remember to come to me."

"That's nature."

Having said that, Chen Mo was still a little speechless, who would really sell things at a loss, listening to what he said miserably, but Chen Mo knew that the price of this kind of material item fluctuated greatly.

Materials are not like equipment, the output varies greatly, once the output is higher than the demand price, it will drop a little, and the output will increase a little below the demand price.

Don't look at the high quality of these two materials that Chen Mo bought, in fact, these two things have a lot of output, and the price is not high.

Moreover, there are fewer people who use dark materials, and the output is more and the demand is less, so the price of things is naturally lower.

And although the quality of some materials is low, they are in high demand, and they need special monsters to be able to produce, which is really expensive.

Chen Mo saw that his uncle agreed happily, and always felt that he had at least a thousand yuan thanks this time.

He picked up the three excellent dark stones next to him and said, "Uncle, can you give me three of this low-level material, just wait for the gift, I really don't have any money." ”

"I'm really convinced of you, and it doesn't hurt to send you three words."

"Thank you."

Chen Mo smiled and handed over the bank card in his hand.

It cost a total of 57,000 to buy skill books and equipment, and 30,000 to buy a backpack, and the money left in the card at this time is just about 11,000.

If this is drawn out again, the bank card that originally had a balance of nearly 100,000 yuan will instantly become a deposit balance of less than three digits before the decimal point.

As Chen Mo clicked to confirm the payment, he also received a notification text message at the same time, and sure enough, the balance in the bank card was already one hundred yuan at this time.

Although today is the most powerful day to spend money in his life, compared to the benefits, Chen Mo is still a lot comforted.

That is, the synthetic thing is bound, otherwise he wouldn't feel distressed for this money if he resold it casually.

Packing the materials into the expansion backpack, Chen Mo returned home again.

Liu Yiyi was still asleep at this time, Chen Mo didn't disturb her, and ran back to the room softly and quickly with small steps.

The materials were already in place, and Chen Mo immediately began to synthesize!

He first tried his hand at synthesizing materials.

If the material can be synthesized from low grade to high grade, it can save a lot of money in the future.

With him put in three Dark Stones of Excellence.

Immediately the synthesis results were derived.

[Congratulations, the synthesis is successful!] 】

"What's this?"

[Better Superior Dark Stone]: It has a better effect than the Superior Dark Stone, and can replace the Superior Dark Stone when used, one is stronger than three.

"What's the matter, the material is not upgraded at all, and it is stronger than three and not stronger than four, is there a difference between it and not synthesizing?"

Chen Mo glanced at the talent effect, and indeed the talent effect did not say that it would definitely be upgraded after synthesis, only that it would get better materials, and the upgrade was better, this kind of thing was better, and there was really nothing wrong with it!

Chen Mo threw it back into his backpack speechlessly, and he had lost hope of making a fortune by synthesizing materials.

He began to continue synthesizing skills.

As the prompt to add special materials appeared, Chen Mo immediately put the dark spar on it.

【Start Success Rate Detection ......】

[The success rate of this synthesis is 100%!] 】

"Whew, the success rate hasn't changed, that's great."

Chen Mo also thought that with the improvement of the grade of synthetic products, the success rate of synthesis would also decrease, but fortunately, there was no at the moment.

[Congratulations, the synthesis is successful!] 】

[Please choose one of the three composition options below as the final composition result!] 】

[1]: Poisonous Corps Orange (Bind)

[2]: Sacred Corpse Orange (Bind)

[3]: Bloodthirsty Corps Orange (Bind)

"This corpse poison effect is really persevering, you have one of the three choices every time!"

Chen Mo was a little embarrassed not to choose it.

Just as a matter of routine, he still took a look at the effects of the latter two options first.

Dark creatures such as skeletons and zombies are protected by heaven when dealing with divine damage.

For example, the Divine Skill Healing Technique, which was originally used to restore health, but if this skill is released on a dark monster like a skeleton monster, it will be directly converted into the same amount of damage.

And the coefficient of healing skills is often higher than that of damage skills, so it is easy for the divine class to easily deal high damage against dark monsters.

The special effect of the second option is that all the dark monsters summoned by Chen Mo can be converted into divine attributes, so that they will no longer be restrained by the divine system.

Although it seems that there is no additional improvement, it only transforms the elemental attributes of the summon, but this turn is a huge improvement.

Chen Mo was actually a little interested in this option, but at this stage, he was not in a hurry to get this attribute, so he turned to the third option.
