"I see, master."

Qiuqiu's eyes flashed and he replied.

After Chen Bing set a series of permissions for Qiuqiu, he left the Clear Sky Design Office and walked towards the trading center of the future city.

Before going to the ruins on the ground, Chen Bing needs to clean up the items he has picked up, and at the same time, he wants to see if he can buy obsidian alloy and upgrade the obsidian exoskeleton armor.

In the future city, there is a special trading place, that is, the future city trading center.

In this sci-fi city, the trading system is more convenient and simple than the average game.

In the trading center, players can rent booths and set prices for items and props that need to be sold, so they don't need to pay much attention.

If the player does not want to pay the rent, or the number of items and props that need to be sold is not large, they can also directly consign the goods to the trading center, but in this case, the player who needs to buy the item needs to search for the corresponding item and prop to see the corresponding product.

At the same time, if a player wants to buy a certain item, they can also place an order in the trading center and set the purchase price and quantity.

In general, the trading center can greatly facilitate the trading of players.

Chen Bing was a little familiar with the operation of the trading center, because the things on his body were basically from Meng Fei and they dropped, and Meng Fei also said the value of these things, Chen Bing quickly checked it, and saw that someone had placed an order to buy things, and the price was about the same, so they all sold it directly.

For the time being, no one has bought a few pieces, and Chen Bing directly hung up the system for consignment.

"Obsidian, no players sell, it seems to be too rare. However, I'm now on a D-Class pass, and according to the library materials, I can buy some rare materials from the system, but the quantity is limited and extremely expensive. ”

Chen Bing searched among the items consigned by the system, but found no shadow of obsidian.

Seeing this, Chen Bing turned in his direction and walked towards a mechanical NPC in the corner of the trading center.

"Hello, adventurer, what services do you need?"

The mechanical NPC asked politely.

"I'd like to see a list of D-class items."

Chen Bing spoke up.

"Clearance satisfied, D-Class Pass detected."

The mechanical NPC's eyes flashed, and a virtual list of items appeared in front of Chen Bing's eyes.

"'Tiger Mecha', 'FN Particle Power Furnace', 'D-Class Mecha Intelligent Assistance System'...... There is, "Obsidian", the price is ...... I'll go, 2 million mechanical coins, the purchase limit is 1 piece! ”

There were a lot of things on the list of D-class items, all of them were rare things, but after Chen Bing glanced at them, he found that things were really not ordinary expensive.

The obsidian alloy he wants costs 2 million mechanical coins for a piece, and the price of the "Tiger Mecha" on the top is as high as 20 million mechanical coins, and this so-called Tiger Mecha is just a D-class mecha.

Chen Bing frantically brushed the level of mechanical designer, plus sold the materials and parts in the backpack, and his full net worth was only 170,000 mechanical coins.

Compared with ordinary players, Chen Bing is already a little rich, but if he wants to buy things on the D-level list, the money is far from enough.

"It looks like we can only count on the ball side."

Chen Bing sighed.

As the pass level continues to increase, the price of items in the shop will drop significantly, and the number of items available for purchase will increase.

At present, Chen Bing can't make up 2 million, and when he gets 2 million, Qiuqiu is estimated to have brushed the pass level to C.

So Chen Bing gave up the idea of pooling money, he looked at the other items on the list of D-class items, and finally bought a 'Super Alloy Dagger'.

The Superalloy Dagger is made from a variety of common metals and is synthesized using the technology of the mechanical family.

The material is not rare, but it has a high hardness, and because it is a cold weapon dagger, the price is much lower, only 100,000 mechanical coins.

For players who venture to explore the ruins on the ground, there are not many opportunities for melee combat, most of the time it is long-range combat, and long-range thermal weapons are much more popular than cold weapons.

The obsidian exoskeleton armor still has almost no defense, and long-range attack weapons are particularly important, but Chen Bing doesn't have a good choice at the moment, although the trading center is very large, almost all the things sold are accessories and materials, equipment like weapons, on the first day of the game, almost no one will sell it.

At this stage, the only players who can get excellent weapons are those who explore the ruins area, for those players, the income that a good weapon can create is far greater than selling it directly, and if you want to buy a good weapon from the trading center, it can only be eliminated by others in a few days.

……

When Chen Bing landed on the ground again, the sky was already starting to darken.

Players who have explored in the wild have chosen to return to the city of the future.

Without a good mecha, it's dangerous to be in the wild at night.

The slightly more advanced mechanical monsters all have scanning abilities, and if the player doesn't have them, they can only be beaten unilaterally in the dark, and they have no power to fight back.

A bright moon had risen from the horizon, but it was not bright at all, but a dark red.

This is due to the influence of the special magnetic field on the ground, and the future city is built at high altitude in order to get rid of the adverse effects of the ground magnetic field.

Chen Bing was equipped with obsidian exoskeleton armor and went deep to the west.

He didn't intend to go anywhere, but he came with a purpose.

In the library, Chen Bing found a sketchy map of the area where the future city was located.

As shown on the map, there used to be a metal smelting factory in the west, which was destroyed after the catastrophe, and according to the general idea of the game, some rare metals and materials must still be found in the metal factory.

However, the distance between the metal smelting plant is not close, otherwise Chen Bing would not need to rush over, if it is too close, it will already be swept by other players.

After night, the number of mechanical monsters in the ruins area increased significantly, and Chen Bing almost killed them all the way.

With the addition of a superalloy dagger, the combat power of the obsidian exoskeleton armor soared.

Using the scanning system to sweep out the enemy's weak points, Chen Bing can use the superalloy dagger to kill with one hit.

Killing all the way, Chen Bing's mercenary level also soared.

Five hours later, the dark red moon had risen in mid-air, and Chen Bing's mercenary level had risen from level 15 to level 22.

"It's finally here."

Chen Bing glanced at the map, and under the dim moonlight, the shadows of the smelting towers appeared.

Chen Bing wanted to approach quietly, but at this moment, a light suddenly appeared in the field of vision of the obsidian exoskeleton.

With a pang in his heart, Chen Bing turned to the side violently.

Bang!

A muffled sound came, and a few meters after Chen Bing's position just now, a bullet hit a big hole!

Player, or monster?

Chen Bing hurriedly found a bunker to hide, and at the same time guessed in his heart. (https:)
