According to Zhang Quan, this kind of dungeon teleportation black card is a rather rare thing, because in addition to the fierce beasts and monsters in the dungeon must drop black cards, there must also be a boss in the dungeon, and the boss must also drop some items with a price, such as equipment, such as skill books.

In this plane, except for some specific beasts, other beasts only drop one item, that is, a black card, ordinary people want equipment or skill books, the only sources are shops and roulette, in which the shop can exchange equipment, and the turntable has a chance to go to the skill book.

The equipment is good to say, as long as the points are enough, it can be exchanged at any time, but the roulette wheel of the skill book is quite egg/pain, this kind of roulette is similar to the form of gambling / betting, after investing a certain number of points, the corresponding items will appear in the roulette, generally ten, and the probability of the appearance of the skill book is only one tenth.

"Senior, do you know what the probability of one in ten is?" Zhang Quan said bitterly: "In the entire Black Iron City, from its establishment to the present, it has been almost fifty years, and it is said that there are less than a hundred people who can obtain skill books, and a considerable part of these skills are non-combat skills. ”

Another named Zhao Lei also sighed: "If ordinary people have great luck and get a combat skill in the roulette, then they can reach the sky in one step, but unfortunately, until now, there is no one in Black Iron City, and there are only a dozen ordinary people in the world who have obtained combat skills, and all other combat skills have been obtained by people from the previous big forces." ”

"Then you all don't have skills?" Lin Feng asked.

Zhang Quan shook his head: "No, I don't have any skills, I usually rely on my own combat experience..."

"Such an apocalypse..."Lin Feng was a little speechless, no wonder human beings were beaten by fierce beasts and retreated, it turned out that many people had no skills, and this apocalypse was not the end of the system flow, although there was a system shop and a system roulette.

"Then you want to go in, right?" Lin Feng raised the black card in his hand.

"Go in, senior, let's go in. Zhang Quan and the four of them nodded hurriedly, their eyes lit up, as low-level personnel, they can usually only kill fierce beasts that are not too powerful, things like the copy of the black card are just famous, this is the first time they have seen it, and at the same time, this is also the closest they have ever been to the skill, if the boss in the copy really drops the skill book.

Lin Feng didn't feel anything, under the command of Zhang Quan, Lin Feng crushed the black cards, and the crushed black cards first turned into rotten, and then gathered again, slowly forming a portal with a whirlpool of one person.

"Senior, this kind of copy is limited in the number of people, the lowest is one person, and the highest doesn't know how much, when the number is full, you can't go in again, senior, you go in first?"

Lin Feng stepped in, and between the light and shadow, he found that he had come to a dimly lit cave, the smell of dirt was very smelly, this should be a cave located underground.

Hmm, two more people came in, one was Zhang Quan and the other was Zhao Lei, and they waited for a few seconds, but the remaining two didn't come in.

"It turned out to be a three-person copy. Zhang Quan hurriedly said: "This kind of copy is okay." ”

The more people who can enter the dungeon, the more powerful the beast in the dungeon, and the greater the difficulty, but the greater the difficulty and the greater the gain, of course, the premise is that it can be beaten, if it can't be beaten, then everything is in vain.

Lin Feng nodded, and the Yuan Shen unfolded, but found that he didn't know what was going on here, and Lin Feng couldn't detect any movement at all.

"How come there are no monsters?"

"Uh, senior, after entering the dungeon, there is generally a corresponding waiting time, the waiting time for this dungeon is three minutes, and now there are still two minutes before the dungeon is opened. ”

"How do you know?"

"There is a timer in front of us, but there is no time in front of us?"

Lin Feng shook his head, estimating that he did not belong to the original people of this plane, so there was no preferential treatment.

Two minutes passed quickly, and at the end of Zhang Quan's countdown, he saw two huge earthworms appear out of thin air in front of the cave entrance, these two earthworms were half a circle larger than the earthworms outside, and they looked much fiercer, and they pounced on Lin Feng left and right.

"This is a dungeon gatekeeper monster..."Zhang Quan hurriedly said, although he has not been to the dungeon, he is an aborigine, there are sources, many masters will send out the information in the dungeon after clearing the dungeon, and it is normal for Zhang Quan to know.

Before Zhang Quan could speak, he saw Lin Feng wave his hand, and the two big earthworms were cut in two, and Zhang Quan didn't even see how Lin Feng made a move.

The two earthworms dropped two black cards, and there were five stars on the black cards, one more star than the one outside, which was indeed stronger, but for Lin Feng, it was still scum, and it was more or less a vegetable.

With Zhang Quan and Zhao Lei, Lin Feng went all the way forward, and this copy was also quite simple, that is, fighting in a cave, during which he also encountered two forks in the road, and there was a big earthworm at the end of the fork, and the six-star black card that fell after killing it.

At the end of the cave, there was a guy who was obviously the earthworm leader, with two big earthworms, of course, they would not bring any obstacles to Lin Feng, and they were killed with the same blow, and the earthworm leader dropped a piece of equipment in addition to dropping a seven-star black card.

This piece of equipment is a piece of clothing, called the Acid Worm Armor, and the equipment introduction is that when it is attacked by melee, there is a certain chance that the enemy's weapon will be deflected, and the hit rate will be reduced, so Lin Feng casually gave the clothes to Zhang Quan.

"It turns out that this is not an earthworm, this is an acid worm..."Lin Feng then realized that the fierce beast he had always thought was an earthworm turned out to be an acid worm.

The boss is dead, and the copy can be regarded as cleared, and the harvest of the entire copy is nearly twenty black cards and one piece of equipment, which is quite shabby in Lin Feng's opinion, but Zhang Quan and Zhao Lei are beautiful, and they thank Lin Feng again and again.

Coming out through the portal again, the sky was already bright, and Lin Feng didn't want to play black cards anymore, he was eager to go to Black Iron City to have a look.

Zhang Quan and the four of them had no objection, got back into the car, opened the accelerator full throttle, and took the forest gate towards the Black Iron City.

Three hours later, the five of them came to the Black Iron City, Zhang Quan stepped forward to negotiate with the people guarding the door, and learned that Lin Feng was actually from the Qingfeng Cave, the soldiers guarding the door were all afraid, and they didn't dare to ask at all, at the same time, Lin Feng found that a few sneaked away, and it was estimated that they went back to report to the high-level of the Black Iron City, and Lin Feng didn't care, he didn't stop it.

"Take me to the store and the carousel. Lin Feng said to Zhang Quan.

Zhang Quan didn't dare to slack off, and walked towards the center of the Black Iron City with Lin Feng, because the shops and turntables were in the center of the Black Iron City.

In the center of the Black Iron City, where there was a huge square, far away, Lin Feng saw the two light screens on the square, at this time, the two light screens were lit, and there were two rows of people queuing in front of the light screen.

"Senior, the light screen on the left is the store, where black cards can be exchanged for points, and the one on the right is the roulette, and the roulette wheel needs a certain number of points to open. ”
