"I didn't expect that the heir of my dignified Chen Group would come to work as a miner and coolie......"

Chen Kai sighed, and then looked at the quiet small valley in front of him.

According to Leo, this peaceful place in front of him is the legendary Wolf Valley, the Wolf Valley is full of dangers, Leo asked Chen Kai not to go too deep, just collect a little ore near the mouth of the valley.

"It's easy to say, the area around this valley mouth is so clean, how can there be any ore that can be mined?"

Chen Kai sighed, and then ordered No. 1 to walk into the valley - although this valley didn't seem to be dangerous at all, since Leo said that it was dangerous, it was better to be careful.

Of course, No. 1 can't be sacrificed casually, the body of the archer is not easy to find, if No. 1 hangs up and the bones can't be retrieved, Chen Kai has to go back to kill the player to get another skeleton archer.

Therefore, Chen Kai cautiously made No. 1 into an all-quality point, even if he really encountered any attacks, with No. 1 71's physical defense and close to 4000 HP, he would definitely be able to run out alive.

Seeing that No. 1 was slowly moving forward, and there was no danger after going deep into the location where there was ore, Chen Kai immediately put down the big stone in his heart, and while directing No. 1 to continue exploring inside, he began to walk to the location where there was ore and began to collect.

Compared with ordinary people who need to carry things like a pickaxe for mining, engineer mining is much simpler, Chen Kai only needs to press the manipulator on the surface of the ore, and the ore can be loosened through high-frequency vibration, and then the ore will be collected into the item space - the powerful force of space transfer will directly separate the ore.

"What's the use of this black ore?"

Chen Kai looked at the black ore in the item space, and used it to check it in a ghostly way, and then saw a message that shocked him.

"Blackstone Mine, which can refine Blackstone."

This is the ore that can be used to refine blackstone!?

Chen Kai was stunned for a moment, and then took the ore out of the item space in ecstasy.

"I don't know if it's going to work......

Chen Kai said and pressed the mechanical arm of his left hand on the ore, and then said silently: "Smelt."

A blue flame came out of the mechanical arm, enveloping the ore, and then Chen Kai saw a smelting progress bar come out, and then 1%, 2%, 3%, ...... The numbers are constantly increasing.

"You really can!"

Chen Kai watched in surprise as the progress bar gradually moved forward, and suddenly stopped when the progress bar reached 10%, and just when Chen Kai was puzzled, the progress bar suddenly disappeared, and then showed that the smelting failed.

"How can this be ......"

Chen Kai looked at the mechanical arm in confusion, and then saw that the blue flame disappeared weakly.

"Huh?"

Chen Kai seemed to think of something, and then opened his attribute panel - sure enough, the mana value was empty.

"The mana cost of smelting is as high as 10 points per second......"

Chen Kai smiled bitterly and asked No. 1 to come back - as soon as the summon is attacked, the summoner will also be pulled into a combat state, losing the ability to regain blood and return to blue.

When the mana was restored to two points, Chen Kai used attribute conversion, adding all 71 attributes to the spirit, and the mana recovery speed instantly increased to 5 points per second.

Of course, Chen Kai's upper limit of mana has also become 1520, and it will take five minutes to recover to the full value, but compared to the base recovery speed of 0.1% per second, it is already much faster.

"If I had Leo's attribute, it would only take 25 seconds to go from empty blue to full blue......"

Chen Kai sighed in his heart: "It seems that cultivating engineering requires a fee, and there is also the problem of attribute selection, fortunately I have the skill of attribute conversion, otherwise I may really have to give up engineering......

Five minutes later, Chen Kai pressed the mechanical arm on the ore again and began smelting.

1%，2%，3%……

Chen Kai was surprised to find that the smelting progress was moving forward at a speed of more than ten times, and then Chen Kai glanced at his attributes and found that his mana was being consumed at a rate of 150 points per second.

"It turns out that it's not a consumption rate of 10 points per second, but a consumption rate of 10% per second!"

Thankfully, in just seven seconds, the progress bar jumped from 0% to 100%, completing the melting.

"No wonder Leo can melt the claws of the attack in an instant, he consumes the blue in one second, that's twenty times that of mine, how fierce is that firepower......"

Chen Kai said in his heart as he picked up a pitch-black stone on the ground and used it to check it.

"Blackstone, special building materials."

"You really can!"

Chen Kai clenched his fists and looked into the depths of the valley, where there were more blackstone mines.

After returning to Manlan again, Chen Kai commanded No. 1 to continue walking, while he and No. 2 followed twenty meters behind No. 1.

Once the ore is discovered, Chen Kai will let No. 1 expand the range of activities, and then switch attributes to start mining and smelting.

In this way, Chen Kai harvested five black stones, and the position of No. 1 also penetrated deep into the middle of Wolf Valley, so it also attracted some dangerous eyes in Wolf Valley.

"Whew~"

Just as Chen Kai was smelting the sixth piece of ore, a gray wolf-like monster with a black glow pounced and bit on No. 1's body, and No. 1 instantly lost 387 points of blood.

"There it is!"

Chen Kai commanded the second attack while using it towards the monster that seemed to be a new breed.

Name: Shadow Wolf

Race: Orcs

Tier: Elite Monsters

Level: 3

Strength: 50

Intelligence: 0

Constitution: 3

Spirit: 0

Dexterity: 12

Health: 1950/1950

Mana: 450/450

Physical Attack: 100

Magic Attack: 0

Physical Defense: 3

Magical Defense: 0

Attack Speed: 1.06 times/second

Movement speed: 5.18 m/s

"The attack is higher than that of a level 3 black wolf, and the skill is also 200 damage, which should be a level 4 skill, and the attack method is similar, all of them are bitten with their mouths."

"However, this physique, blood volume and defense are a little lower than that of the black wolf, and if the first and second kites together, they can be killed in 10 seconds."

The Shadow Wolf's hatred pattern seems to be similar to that of the Black Wolf, and after being shot twice by Two, he drops One and runs towards Two.

Chen Kai commanded No. 2 to shoot arrows while retreating in the safe direction they came, and then he ran away, preparing to wait for the attribute conversion to cool down, and brush No. 1 into the same 20 physique and 51 strength attribute as No. 2.

Just when Chen Kai finished brushing the attributes of No. 1 and then chased in the direction of No. 2, Chen Kai was surprised to find that the ghost wolf's body suddenly became blurry during the run, and then disappeared.

"What's the situation?"

Just when Chen Kai was puzzled and No. 2 also stopped because he had lost the target of the attack, the phantom wolf suddenly appeared next to No. 2, and then bit on No. 2, and a damage number of 540 floated up from No. 2.

"It's ...... Stealth!? ”
