Liu Hai found that it was really different with mining techniques. Basically, one ore was put into the bag in about five minutes. After another 4 hours, when the 50th ore was dug by him, he decisively devoted all his experience value to the proficiency of mining techniques.

Only a flash of light was flashing, and mining techniques changed.

【Skill: Mining Technique】

Level: Proficiency

Proficiency: 0/1000 (Available experience value increases)

Effect: There is a certain chance of mining ore.

"Yes, the small chance becomes a certain chance, and great progress is made!"

Bangs continue to work hard, pick up the mine hoe and dig.

"Ding, congratulations on getting Level 1 Iron Ore*1"

"Ding, congratulations on getting the [Mining Technique] proficiency of 0.5 points"

"Congratulations on getting 1 experience point"

Within one minute, a piece of iron ore was dug out. Although the proficiency was reduced by half, the experience value was still strong. In this way, only more than 600 ores could be upgraded.

"Damn, it's so good?"

The bangs shone with their eyes, full of motivation, and they dug up the ore selflessly, entering a state of indescribableness.

I don’t know when someone patted his shoulder: “Brother, brother.”

After being photographed several times in a row, Bang Hai only came to her senses. She raised her head blankly, looked at the familiar big green bull player in front of her, and asked in confusion: "What's wrong?"

"Um cough." Da Qingniu coughed, "Brother, I think you have been digging for a long time. You must have dug a lot of ore, right?"

Liu Hai subconsciously glanced at his backpack and nodded, "I've dug some."

Daqingniu's eyes lit up and he laughed, "How about it, brother, how about selling your ore to me?"

Liu Hai shook his head and said, "No, no, no, I want to hand in the mission. I am a life player. This is my capital to make a fortune. I am not the kind of short-sighted person!"

Daqingniu observed the bangs and smiled and said, "Price is not a problem."

Liu Hai said: "I am not a short-sighted person...how much does it cost?"

Daqingniu opened his mouth and said, "1 ore and 1 credit point, and I will give 150 credit points for 100!"

He added: "150 credit points, you've made a lot of money!"

"If you don't sell it, you'll be the first step ahead of others. If you buy it, you'll be one day faster than others."

Da Qingniu glared at him, hesitated for three seconds, and said, "Yes! I bought it!"

Bang Hai gave a thumbs up: "Brother, you have a good vision! This is a perfect investment, and I sold it only after I can't get it out. Oh, I'm a little hesitant!"

"Trade!" Da Qingniu urged.

The bangs have no choice but to put 100 ores into the trading box.

In less than a second, 1,000 credit points were transferred to his account.

Liu Hai smiled with satisfaction and said, "Happy transaction!"

When Daqingniu received the ore, he immediately ran towards the village without stopping.

Bang Hai shrugged, then his eyes turned and ran towards the village.

Follow Da Qingniu all the way back to the blacksmith shop.

Daqingniu handed over one hundred iron ore to the blacksmith.

The strong blacksmith glanced at him, waved his hand, and a light fell on the big green bull.

Da Qingniu shouted in surprise: "I have learned mining! Haha!"

A player next to him looked over and asked, "How did you learn it?"

Da Qingniu covered his mouth and said, "Of course I'm going to hand in ore to learn skills!"

"Where did you get the ore?"

"Hehe, of course it was dug out!"

The big green bull ran towards the mine cave no longer explained.

Liu Hai shrugged and said speechlessly: "So it's really just learning mining? But I've learned it!"

He glanced at the more than 500 pieces of iron ore left in his backpack.

Liu Hai curled his lips and came to the blacksmith shop. He found the strong blacksmith uncle and said, "Master, I'm here to hand in the mission!"

The blacksmith shop master who was pounding the iron ore expressionlessly suddenly stopped, looked at him strangely, took the ore with his bangs, and began to say, "You have already understood the mining technique, I can no longer teach you!"

Liu Hai's face turned pale: Return my ore quickly...

The blacksmith paused and said, "But you can buy more advanced ore hoes with ore or gold coins!"

Liu Hai's face returned to her joyful look, and she rubbed her hands and said, "What kind of mine hoe is there?"

The blacksmith waved his hand and a screen appeared in front of his bangs, with a display of a mine hoe on it:

【Ordinary Tool: Red Copper Mine Hoe】

Level: First-level lower-grade

Price: 5 silver coins or 500 iron ore

Effect: Mining speed 1

【Ordinary utensil: Gilded ore hoe】

Effect: greatly improve mining speed (300%), with a certain probability to increase shipment quantity and quality

Liu Hai pondered for a second and walked out of the blacksmith shop.

When they arrived at the street stall area where players gathered, they immediately sat down, stood up the stall, and shouted: "I've sold ore, I've sold ore!"

Liu Hai took out 200 pieces of ore he dug and put them on the stall, and priced them for 10 copper coins per piece of ore.

"Sell ore! Sell ore!"

Bangs shouted.

The players immediately surrounded him.

"Damn it! You're so dark!"

"You sold 10 copper coins for one ore, you're losing your mind!"

"Smart Battle!"

"Someone buys it, I'll eat x on the live broadcast"

The bangs are unmoved.

A player asked, "Brother, can you sell the credit points?"

"No! I'm not a short-sighted person, I only exchange game coins!" Liu Hai said calmly, and the expression on his face was not loose at all.

The player saw that there was no chance and then he ended.

Some players don’t believe that someone will buy it. They are idle and just stand by and watch.

I didn't care about my bangs and sat there for ten minutes.

Finally, a player wearing armor came over with a few people.

"Wow, look at the equipment on this person! There are 3 first-level mortal weapons, which is too luxurious!"
