Leo nodded: "Of course there are black stones, how many do you want?"

Chen Kai hurriedly said, "I want ten."

"Okay."

Leo said as he turned his gaze to his right, then his right hand slicing through the air.

Chen Kai looked very puzzled and asked, "Mr. Leo, what are you doing?"

"I'm looking for the price of the black stone, I haven't sorted it out for too long, it's a mess in the panel, you wait a while, I'll sort it out."

Chen Kai was stunned after hearing this: "Panel? Do you have panels too? ”

Leo blinked, looked at Chen Kai suspiciously, and said, "Of course, every intelligent creature will have the ability to use various panels after being guided by the God of Contract."

"Is it really just a game?"

Chen Kai thought for a while, if this was really just a game, how could NPCs use the panel, and judging from Leo's performance, his intelligence was almost on par with humans, but such intelligent technology was unheard of before the appearance of "Natural Disaster".

At this time, Leo paused as he swiped the panel, and then said, "I found it, the price of the black stone is two hundred gold coins each, and ten pieces are two thousand gold coins."

"Huh......"

Chen Kai came back to his senses, and then he was stunned again - he suddenly remembered that he had no money at all, so how could he buy Blackstone?

Leo looked at Chen Kai stunned and didn't react, and suddenly frowned: "You won't be without money, right?"

Chen Kai touched his head in embarrassment, and then asked, "Do you accept things here?"

Leo sighed and said, "Yes, but the purchase price is sixty percent of the sale price, which you can accept, right?"

"No problem."

Chen Kai's voice came from the soul speaker: "After all, from acquisition to sale, renovation requires cost, inventory requires cost, and sales also require cost, plus there is a risk of not being able to sell out and losing money, and there is a risk of capital reduction and turnover difficulties, it is normal for the purchase price to be low."

Leo looked at Chen Kai in surprise: "I didn't expect you to know a lot."

Chen Kai smiled slightly in his heart, after all, he was the heir of the Chen Group, and of course he had no problem with this level of cognition.

And. In order for Leo to understand, there are many technical terms such as inventory turnover that he doesn't use, but just uses some simple, easy-to-understand words to explain.

(Of course, the main reason is that a certain scumbag author doesn't understand those professional terms very well, so ...... ）

"Actually, I don't really understand what you said, but if you can accept the purchase price of sixty percent."

Leo said and stretched out his hand towards Chen Kai: "Bring it, let me see what good things you have."

The first thing Chen Kai took out was the white equipment attack claw that had exploded before and was useless.

"What kind of garbage stuff is also sold to me......"

Leo said in disgust, "30 gold."

Chen Kai's eyes widened: "So little!?"

Leo said angrily: "This kind of white equipment that is exploded by monsters below level 10 is sold for 50 gold in the shops of various towns, if it weren't for your sake, I wouldn't be too lazy to collect this kind of garbage equipment."

"30 is 30, no matter how little is money."

Leo nodded, took the attack claw from Chen Kai's hand with his left hand wearing a mechanical arm, and then spread his palm upwards and shouted, "Lian!"

I saw the claw of attack float up from Leo's palm, and then blue flames appeared on his left hand, and the claw of attack quickly began to melt.

Chen Kai looked at this scene in surprise: "What are you doing!?"

"Smelting."

Leo looked at Chen Kai with a smile: "I'm not a forger, so I can't play synthetic equipment, but I can smelt equipment into materials and use it."

"Who is the forger?"

"A blacksmith is also a subclass, just like an engineer."

Leo glanced at Chen Kai, and then explained to Chen Kai about the sub-profession.

There are four subclasses: Blacksmith, Enchanter, Apothecary, and Engineer.

The ability of the forging master is to forge equipment, this sub-class can forge raw materials with different attributes into equipment with corresponding attributes, there is a certain chance that three pieces of equipment of the same level can be combined into more advanced equipment, and the attributes of equipment can be controlled to a certain extent.

The five dark gold rings on Leo's right hand that increase the spirit of 3 and 50 are from the hands of the forger.

Chen Kai was naturally very curious when he heard this, because Leo, like him, could only equip a maximum of six pieces of equipment, why didn't Leo wear equipment like weapons and robes, but chose five rings?

Listening to Chen Kai's question, Leo said with a smile: "My skills are all engineering skills, all the damage is fixed damage, the attack power is meaningless to me, I only need spiritual attributes, and the spiritual attributes are most likely to appear, which is in the position of jewelry."

Subsequently, Leo continued to explain other sub-professions to Chen Kai.

The Enchanter's abilities are naturally enchanted, and they can attach a variety of attributes and abilities to equipment, and most importantly, the Enchanter's abilities are arrows that can be applied to archers, as Enchanters are highly sought after by archers.

The ability of the pharmacist is naturally to refine medicine, in addition to the general blood recovery medicine, the pharmacist can also make a variety of attribute potions and ability potions, which also greatly improves the combat effectiveness.

As for the engineer, Leo is gushing and blowing, oh no, it was more than an hour of talking, and Chen Kai summed it up - the project is invincible, but it is a little time-consuming, a little laborious, and a little expensive.

Chen Kai sighed depressedly in his heart, he naturally knew that there was a lot of water in Leo's words, if he could turn into a pharmacist or a forger, he could quickly improve his combat effectiveness, but he had become an engineer and could not change it.

Leo didn't notice Chen Kai's expression (of course the skeleton didn't have an expression...... At this time, he was in a good mood, and said to Chen Kai with a smile: "Okay, if there is anything else to sell, take it out."

Chen Kai immediately took out the fatal blow skill book.

"Huh?"

Leo glanced at Chen Kai in surprise: "It seems that you are lucky, you even have a skill book."

"Skill books are rare?"

Leo nodded: "Of course, the skill book will only drop when monsters above the boss level die, and the chance is one in a thousand, do you say it's rare?"

"One in a thousand?"

Chen Kai was stunned for a moment, and then smiled slightly in his heart - he didn't expect that the first time he killed a leader-level monster, he would explode to something with a 1 in 1,000 chance, it seems that the goddess of fate is still quite attached to herself.

"The value of the Critical Strike skill book is relatively high, the market price is one thousand gold coins, if you want to sell it, it is six hundred gold coins."

Although he accepted the purchase price, he suddenly lost four hundred gold coins, and Chen Kai was also distressed for a while - if he could sell it at the market price, he would have the money for the 10 black stones.

"Do you really want to sell this skill book? You're only two levels now, you're only three skills, and you don't have any attack skills, so if you learn to hit a critical blow, the output will still be considerable if you adjust more power with attribute conversion. ”

Chen Kai's eyes widened: "How do you know my skills?"

Leo smiled slightly, then pointed to his left eye: "I can see this if I have this."

Chen Kai looked at Leo's left eye suspiciously, and then saw that Leo's left eyeball suddenly lit up with some complex blue lines, these lines were complex and mysterious, and there were faint traces of engineering.

"This is one of my skills, called Blue Light Eye, which can be used to view more in-depth information about the target, such as equipment attributes, skill descriptions, and so on."

"In addition to this, the Blue Light Eye can also form vision abilities similar to mechanical satellites, and can even see most invisible units in the field of vision."

Chen Kai was stunned: "Most of the stealth units?"

Leo nodded: "Yes, the general stealth skill is achieved by using functions such as light refraction, and a skill like this cannot hide the detection of heat energy and air flow by the blue light eye."

"But the blue light eye is not omnipotent, there are many skills that will have a strong hidden effect, which is similar to the effect of parallel space, and the body is completely isolated from the real space, so it will not be detected by the blue light eye."

Chen Kai was surprised: "Isn't the enemy with a strong concealment effect still able to approach and attack you casually?"

Leo smiled: "It's not that simple, first of all, skills with strong hidden effects generally have a short duration, most of them are less than three seconds. The detection range of the blue eye is fifty meters in radius, and it is still difficult for the enemy to get close to me directly within three seconds. ”

"Secondly, skills with strong concealment effects are not uncontrollable, like some special props such as Shadow Dust, Sentry Guards, and some special skills, you can crack the parallel space stealth effect of strong concealment skills."

Chen Kai nodded slowly, as if he didn't understand.

"Okay, don't talk so much, do you still sell this skill book?"

Chen Kai hesitated for a moment, and then said firmly: "Sell!"

"Don't think about it too much?"

Chen Kai shook his head and said: "I have thought about it very clearly, for me, in addition to the advancement, the most important thing is safety, plus what I want to advance is the direction of the necromancer, and I will not cultivate physical attacks, so the critical blow has no effect on me, it is more practical to sell it."

Leo nodded: "Okay, the fatal strike skill book is counted as six hundred, and if there is anything else, take it out, I'll count it for you."

"Uh......"

Chen Kai touched his head in embarrassment: "I don't have anything."

"Huh?"

Leo was stunned for a moment, and then said with a wry smile: "You only have 630 gold coins, and you can't buy ten black stones."

"I'll go farm the black wolf again and get enough loot."

"Don't!"

Leo hurriedly waved his hand: "I don't want to see these garbage in vain again."

"Uh, what should I do then?"

Leo sighed: "That's it, I'll give you a mission, it's much more reliable than you killing monsters and making white clothes."

"Mission?"

Chen Kai was stunned for a moment, and then the task panel popped up in front of him, and a task was displayed on it - to go to Wolf Valley to collect ore instead of Leo, which was also purchased at sixty percent of the market price.

"It's going to ...... Mining? ”
