"black!"

When Chen Kai felt depressed when he thought that the blue light crystal fragment was sold for 100 gold coins, he could only use his wry face to shoot the third and fourth level shadow wolf in the Wolf Valley.

Since Chen Kai cleared the Black Stone Mine in Wolf Valley, the Black Stone Mine has never been seen again. In Leo's words, it is necessary to wait until some mysterious magic power underground seeps out before it can condense into a Black Stone Mine on the surface.

As for the large black stone floor deep in the Wolf Valley, Leo said that he could not even pry it up, let alone refining it. The black stone floor was probably created by the power of God.

"Why did God create a black stone floor? O must be bragging here, it must be because he is too lazy to do it."

Chen Kai angrily commanded No. 1 and 2 to kill shadow wolf after shadow wolf. After Chen Kai was promoted to the elite level and his basic health increased to 1,800, No. 1 and No. 2 were no longer afraid of being killed by the shadow wolf that suddenly appeared in seconds. Therefore, No. 1 and No. 2 can directly use pure power points, with an attack power of up to 250. The time required to kill a level 3 shadow wolf is reduced to 4 seconds.

Therefore, after eight hours of fighting and the sky turned dark, Chen Kai returned to the wild shop and poured out a pile of equipment in front of Leo.

"Be good, those god-blessed people have just arrived. There are so many of them. The black wolf that has been killed for a day, it feels like it is just like you."

Leo counted and said, "35 pieces of white, 4 pieces of green, 30 gold in white, 120 gold in green, 1530 gold in total."

Chen Kai nodded and said, "I want 10 blue light crystal fragments."

"Okay."

Leo smiled and handed Chen two bags: "Here are 10 blue light crystal fragments and 530 gold coins."

"What do I need to do if I want to upgrade the Blue Light Eye?"

Leo smiled and said, "It's very simple. Melt the blue light crystal fragments separately. Note that they are melted into 10 small blue light beads, and then remove the blue light eye at your left eye. There are outer hexagons and inner diamonds in total. There are 10 nodes in it. You can complete the upgrade by just inlaying 10 small blue light beads."

"oh?"

Chen Kai listened to the fun, then came to the table and sat down. Then he took out an empty bag and spread it on the table, and then took out a piece from the bag containing the blue light crystal fragments.

"Smelting!"

With Chen Kai's current blue amount of up to 2850, the small blue light beads can be melted out in one second. In a short while, 10 small blue light beads were placed on the empty bag.

Chen Kai stroked the robot hand on the Blue Light Eye, and heard a sound of scratching, and the Blue Light Eye was taken down by Chen Kai.

Then Chen Kaixin thought about it, and something like tweezers stretched out from his mechanical hand. There seemed to be something similar to a suction cup on the surface of the tweezers. The smooth small blue light beads were steadily clamped up by Chen Kai, and then embedded into the node of the Blue Light Eye.

Soon, 10 small blue light beads were also inlaid. Chen Kai immediately picked up the blue light eye and put it back on his left eye.

Skill Name: Blue Light Eye

Continuous blue-consuming manufacturing of blue-ray satellites, strengthening map panels, and a radius of 20 meters in detection range;

All the target information that does not exceed your level 2 can be obtained;

It can crack the stealth effect of ordinary stealth skills with skill levels not exceeding the Blue Light Eye level;

Upgrade requires: Level 2 of engineering manufacturing and three blue light crystals.

Chen Kai's expression froze, then he looked at Leo: "What is the blue light crystal?"

Leo said with a smile: "It's a complete blue light crystal, which can be melted from 10 pieces of blue light crystal fragments. After melting into blue light crystals, and then further melting, you can get blue light beads, four blue light beads, and the 10 small blue light beads on your current Blue Light Eye can also be melted into one blue light bead, exactly four."

"When you upgrade your engineering manufacturing to level 2, you can inlaid four blue light beads into the four diamond-shaped nodes in the inner layer of the Blue Light Eye, and you can upgrade the Blue Light Eye to level 3."

Chen Kai's dull voice came from the soul speaker: "I guess, does it take six blue light crystals to upgrade to level 3 and level 4?"

Leo nodded with a smile: "Yes, you really have an engineering mind."

Chen Kai smiled and said, "I guess again, can ten blue light crystals synthesize something?"

Leo laughed: "It's very good, you can learn from it. Yes, ten blue light crystals can synthesize an intermediate blue light crystal, ten intermediate blue light crystals can synthesize an advanced blue light crystal, and ten advanced blue light crystals can synthesize an upper..."

Leo couldn't continue, because Chen Kai's deafening roar came from the soul speaker: "I'll beat you ***..."

...

After asking that the Blu-ray crystal is not unique to Leo and is easy to buy in the outside world, Chen Kai finally gave up the idea of ​​pursuing Leo, a profitable businessman.

"My God, it will cost ten million yuan to reach the level 10 of the Blue Light Eye. Is engineering something that people can play with??"

Chen Kai thought in his heart, crying and without tears, how much money would it take to sell for ten million yuan...

Leo said with a smile: "Young skeletons don't underestimate themselves. There are many opportunities in the outside world, and you still have a chance for ten million."

"I believe you, you old man is so bad..."

"Don't say that to me."

Leo smiled mysteriously and said, "Last time you asked me if there is any skill to increase the number of summoned skeletons. I happened to remember something today, or what you want."

Chen Kai shouted in surprise: "Really? What's the matter?"

"Do you know the Dark Ranger?"

Chen Kai tilted his head and asked in confusion: "Dark Ranger?"

"Dark Ranger is a legend."

Leo said respectfully: "She was once one of the supreme leaders of the Elf Clan. She was killed after a war with the Scourge, and was later resurrected by the Death Knight to become a necromancer. She was arrogant and unwilling to be a slave to the Scourge, so she brought a group of banshees to rebel from the Scourge and joined the Dark Council."

"Uh, I'm a little confused. What are the Scourge and Death Knights you mentioned?"

"Did you never read a book before your lifetime?"

After Leo finished speaking, he slapped his head: "Yes, I forgot that you are not from this world. Okay, let me tell you about the composition of this world."

"More than two hundred years ago, the holy war had not begun at that time. There were six gods in this world, namely the Goddess of Light, the Goddess of Nature, the Goddess of Beasts, the Goddess of War, the Lord of Darkness and the Lord of Death. Among them, the Lord of Death is the most powerful, while the Lord of Darkness is the weakest, and he is a dog-legged dependent on the Lord of Death. The other four gods, the Goddess of Light and the Goddess of War are a pair, and the Goddess of Nature is closer to the Goddess of Beasts."

"Geographically, the Lord of Death has been staying in the vast wild area in the west. The Lord of Darkness established a dark empire next to the wild area. The Goddess of Light and the God of War established a light empire in the east, while the Goddess of Nature and the God of Beasts established a Feiling Empire in the north."

"The six gods were in peace, but they didn't know what the Death Lord had gone crazy. Suddenly, they sent out a large number of undead creatures, known as natural disasters of death, and began to attack the Feiling Empire and the Light Empire, setting off a holy war."

"In this battle, six gods fought the sky and the earth, the god of war was killed in battle, the beast god was seriously injured and disappeared, the master of death was scattered, and only three of the six gods were left at once."

"As soon as the Goddess of Light who lost her husband got angry, she drove the Lord of Darkness to the wilderness. The Dark Empire and the Empire of Light were re-divided by her and changed to the Dragon Empire and the Izumo Empire."

"However, after the holy war, the remaining three gods seemed to be injured and disappeared for a hundred years. After the Scourge was severely injured, they did not know where to go. The dark ranger who turned the Scourge knew that it would not be accepted by the people of the three empires, so he joined the Dark Council and lived in the wilderness."

Chen Kai nodded. After hearing Leo's talk about this whole lot, he finally had a relatively clear understanding of the world.

"In the hands of the Dark Ranger, are there any skills that can increase the number of skeletons I summon? "

Leo nodded: "Over the past century, because the influence of the faith of Light has become increasingly powerful, the tasks of hunting the faith of Darkness are increasing. In addition, the proud guys of the Elf Clan believe that the existence of the Dark Ranger has defiled the Elf Clan, so the area where the Dark Ranger is located has been targeted."

"The occasional attack of Dark Ranger also lets everyone know about her terrifying ability - she seems to be able to summon the creatures she killed directly into skeletons, and there is no limit on the number of limits."

“No quantity limit!?”

Leo nodded solemnly: "Her most classic move, a huge black light arrow penetrated through the middle of the army, and hundreds of people on a line fell down, and the next second hundreds of skeletons stood up, and they were 30-level leader-level skeletons!"

Chen Kai clenched his fists excitedly, and then he let go the next second, saying deflatedly: "Will Dark Ranger teach me such a powerful skill?"

"How can you know if you don't try it?"

Leo raised his eyebrows and said, "You are a necromancer, and you are in a similar situation to her. Compared to other creatures, you are more likely to get this skill, aren't you?"

Chen Kai nodded: "You are right! I will try my best."

"Also, I have a special idea about what you said to strengthen the output ability of the skeleton. I wonder if you are interested."

Chen Kai was stunned: "What's your thought?"

Leo smiled slightly and began to talk about his crazy idea...

...

"I'll go, I'm going crazy, no, you're going crazy!"

Chen Kai covered his head: "Are you sure this is really OK? You can create this skill!?"

"It's feasible in theory, but to achieve it, I have to do some experiments."

Leo then looked at Chen Kai with fun: "But this is your business. I can't let me bear the cost of this experiment, right?"

Chen Kai gritted his teeth fiercely, and his fierce voice came from the soul speaker: "How much do you want?"

"I don't want money this time"

Leo smiled slightly: "I need Mithril..."
