The machine purchased by Song Jian is called "Ore Processing Machine", which integrates the functions of crushing, decomposition, and extraction, and can directly purify the ore into the corresponding finished product;

For example, if you put in a unit of iron ore, you can directly decompose a piece of metal iron ingot, and if you put in a piece of gold ore, you can directly come out of a complete piece of gold;

This ore processor looks like a rectangular metal box, more than half a person high, and when used, it must be taken out of the package, and it can be retracted into the package box when not used, which is very convenient.

This item is also extremely expensive, requiring 2,000 Doomsday Coins, which the average player can't afford at all;

What is the price of the material and what is the price of the finished product, after Song Jian first contacted the Doomsday Supermarket, he had a deep understanding that a piece of "zombie meat" can only get one doomsday coin for sale, but when it is made into "fried meat" or "barbecue", it is worth twenty or thirty doomsday coins, and the price has increased by twenty or thirty times;

Obviously, if the ore is sold, it can only be regarded as a material, and the price will be extremely low, but if the finished product is decomposed, then the price will naturally increase accordingly;

With the light of the convenience store, Song Jian walked all the way towards the subway stand, continued to walk forward for a few hundred meters, and a faint light appeared in front of him.

The concrete passages on both sides of the railroad tracks have been covered by a layer of rocks, and the inside of these rocks exudes colorful light, which looks dreamlike and beautiful;

In the depths of the subway tracks, Song Jian saw a subway that had corroded and did not look good, which had broken away from the track and was lying horizontally in the passage, the surface covered with a thick layer of green embroidery;

Song Jian jumped off the track from the platform, took out a palm-sized compass, and probed left and right; This is the "prospector" he just bought from a convenience store to detect ore within three meters of the surrounding area;

The prospector looks like a radar, with a metal shell, the front is inlaid with a layer of transparent glass, the center is a pointer, and below the pointer is an LCD screen, on which a thin line is displayed, this line is like a life detector in a hospital, constantly beating slightly, and the pointer of the prospector is constantly shaking with Song Jian's constant change of position;

Song Jian walked forward along the rocks on both sides of the track, and as soon as he walked five or six meters, the prospector made a rapid "click" sound, and the pointer "clicked" to the far left, and at the same time, the LCD screen under the pointer, the constantly beating line, also began to beat violently;

Song Jian walked according to the pointer, here is a rock wall emitting red light, Song Jian kept moving up and down on this rock wall, and when he moved to a position of one meter from the ground on his left hand, the transparent glass of the entire prospector suddenly emitted a soft green light;

"This is it!" Song Jian put away the prospector and threw a fist at the rock wall;

Bang bang bang~

Cracks appeared in the hard rock wall, debris flew around, Song Jian felt a slight stinging pain from his fist, it seemed that this was more difficult than collecting rocks;

After smashing for more than ten minutes, a crimson light flew out of the rock wall and entered Song Jian's parcel bar;

System: When you collect one unit of "Blood Stone", the Quarrying experience will increase by 25 points;

"Blood Stone?" Song Jian's eyes lit up, the blood pool was upgraded from the first level to the second level, and he needed a hundred units of blood spirit stones, he originally wanted to spend money to buy them, but the blood spirit stones were too expensive, so Song Jian put this matter down, but he didn't expect that he could collect blood spirit stones here, which was really unexpected;

"Bloodstone (White): Material, can be used for enchantment, engineering, pharmaceutical; Requirements: Possess corresponding crafting skills; ”

Looking at the blood spirit stone that emitted a faint red light in the package bar, Song Jian secretly said in his heart: "This blood spirit stone is really widely used, no wonder the price is so expensive." Could it be that this is a deposit of bloodstone? If that's the case, then I'm going to get rich. ”

Taking out the prospector, Song Jian continued to explore;

The prospector is very convenient to use, and it can accurately find the specific location of the ore, but it takes a bit of time, more than half an hour, Song Jian only collected three units of blood stone;

"It's better to complete the test task first, as long as you know the collection location, the blood spirit stone can be collected sooner or later." Song Jian said secretly in his heart.

Directly abandoning the ore in this red area, Song Jian walked along the track towards the depths of the passage;

Obsidian should be an ore area that emits black light, and soon, Song Jian saw that the rock wall on the side of the train lying horizontally was emitting black light;

Jumping on the train, Song Jian took out the prospector and searched for it;

The prospector could only detect the location of the ore, but it could not detect what type of ore it was, and Song Jian could only guess by the name of the ore that the obsidian should be in this area that emitted black light;

Da Da Da ~ The prospector made another hurried sound, and following the direction indicated by the pointer, Song Jian walked towards the middle of the train;

"This is it!" Seeing the soft green light emitted by the prospector, Song Jian smiled slightly and threw a punch towards the rock wall;

At this moment, Song Jian suddenly felt a slight tremor under his feet, and a low roar came from the train carriage under his feet;

"Monster!" Song Jian had a flash of inspiration in his mind, put away the prospector, drew his dagger, and prepared to jump off the train;

Rumble~

The carriage under his feet suddenly burst into a big hole, and a withered arm stretched out from the hole and grabbed Song Jian's ankle tightly;

Immediately afterward, a strong force came, and the monster under his feet seemed to want to pull him into the carriage;

Song Jian frowned, and suddenly his body turned into a cloud of black mist, floating upward;

The monster stretched out its arms and probed around two more times, and after finding that Song Jian was lost, he immediately became furious, kept roaring and roaring, stretched out his two arms to the hole, grabbed the surrounding iron sheets, and tore them to both sides, and after a while, he directly tore open a large hole for one person to enter and exit;

Soon, a zombie with a red upper body came out of the big hole and roared towards the black mist overhead;

The surface of this zombie's body has a thick layer of scales, exuding a dark light, as if it is covered with a layer of iron armor, and even the sides of the cheeks are covered with scales the size of fingernails;

"LV10 Iron Armor Zombie (Elite), HP: 1100/1100, Trait: Super Defense, Skill: ???"

"Level 10 Elite Boss, this is a little difficult!" Song Jian stared at the boss who kept roaring and roaring below, and felt a little tricky, he didn't come here to fight monsters and kill bosses, but to mine, but if he didn't kill the boss in front of him, he couldn't continue to collect;

"If my bazooka hadn't broken, it wouldn't be very difficult to deal with this boss, but now ......" Song Jian hesitated for a moment, controlled his body, and slowly fell towards the boss;
