In the next eight hours, the acquisition speed of black crystals produced an amazing but expected increase.

The black crystal worth 3460 points of black flame coins was collected directly by 17 worker bees. The average contribution of one to one within eight hours was 26 points, which is equivalent to 2 black crystal grass or 6 black crystal flowers.

This is still the result when the black crystal trees cannot be cut down.

However, at the same time, these worker bees finally began to suffer losses.

After all, under each black crystal vine, there is a poisonous snake or other monsters guarding it. If the worker bees want to seize the energy source on which they rely for survival, they will naturally be subject to the heaviest counterattack.

Although Midi and others started a clearance and tried to clean up all the monsters attached to the black crystal vine, after all, they only had four.

Not every monster will be killed with one blow, and at least many will escape.

In addition, not every black crystal vine will be found by Midi and others and cleaned up the surrounding environment.

Once the escaped monster returns, the revenge attacks will become more and more fierce.

If the worker bee directly finds a black crystal vine that Midi and others have not discovered at all, it will undoubtedly be directly attacked by the alarmed monster.

After eight hours, the losses of 17 worker bees actually reached nearly 50%. B of the worker bees were destroyed, and one of them was stopped on the way back with a large number of black crystal plants.

If all are intact, perhaps the output of black crystals can directly exceed 4060 points.

"The exploration has been almost done within a radius of hundreds of kilometers. If we explore further, it will probably waste too much time for the four of us. These worker bees can no longer collect them in such a fragile way. In addition, it is almost time to take action against this black crystal tree." Midi made the decision.

Carrying 3460 black flame coins, Midi came to the Dragon Temple again, but compared to the previous two times, he seemed much more confident this time.

"It is a good job to accumulate black flame coins of more than 10,000 in a short period of time." Dragon Shou glanced at Midi and showed a slightly surprised expression, "What do you want to exchange for this time?"

Since the entire low-level redemption list is open, although Midi only redeemed two devices: "worker bee" and "honey pot" at the beginning, in fact, in the past two days, he has been thinking about what kind of development route to take next.

Since he came here, Midi certainly had repeated considerations and calculations in his mind. As soon as the light curtain in front of him unfolded, he immediately selected a few new equipment without hesitation.

First of all, it is the "grabber" of the advanced black crystal collector worth 1060 black flame coins.

This is a collector that can cut down black crystal trees.

Although the price was twenty times more expensive than the worker bee, Midi gritted his teeth and took it down without hesitation.

Because he knew very well that it would not be enough to have worker bees alone if he wanted to occupy a leading position in the resource war.

The lowest-level alchemy puppet may make people feel that it is cheap and very cost-effective in the early stages, but as the number increases, the damage rate continues to increase, coupled with low efficiency, difficult management, etc., various problems are enough to completely lose their value in price.

Worker bees can only be used in this early stage. One day in the future, when they develop to a certain level, Midie will definitely abandon all worker bees.

That's why he exchanged for a "cutter" to prepare for future development.

Of course, at this stage, since Midi mainly collects three extremely scattered plants, such as black crystal grass, black crystal flowers, and black crystal vines, worker bees are still indispensable.

However, while redeeming a large number of worker bees, he also exchanged for another type of alchemy puppet.

The guard puppet "Soldier Bee" worth 156 black flame coins.

The worker bee and the soldier bee complement each other can undoubtedly greatly reduce the loss rate. Otherwise, after the initial spread, the loss of the worker bee itself alone will be enough for Midie to drink a pot.

The last device that Midi exchanges is another alchemy puppet "Flying Eye" worth 36 Black Flame Coins.

This flying eye has the lowest level of "compound eye" black crystal sensing ability, the collection ability of "worker bee" and the combat ability of "soldier bee". In addition, it also has terrain mapping ability and continuous flight ability of a certain altitude.

It can be said that this is a multi-functional alchemy puppet.

Midi exchanges for "Flying Eyes" to allow them to replace themselves and explore a range beyond a radius of 100 kilometers.

Although Midi can't eat the area where the three black crystal trees are located at this stage, Midi can predict that after other teams also enter the black crystal forest and start a battle for resources, this war will definitely not start within such a small range.

If the Black Crystal Forest is only this small size, let alone the real dragon body-forging method worth 1 million, even the intermediate exchange list will probably not be able to be opened.

Since the setting value of the high-level list is 1 million, Midi can imagine that the area of ​​this black crystal forest will probably not be smaller than that of the Gran Forest next to the Kingdom of Belmar.

Only as large as a small country can one fight a resource war.

After returning to the base, Midi immediately released all the worker bees, soldiers bees, and several expensive flying eyes that were exchanged, and continued to restrain resources without stopping.

At the same time, the "logger" worth 1,060 black flame coins, which was more than five meters high, was also released at the same time.

The shape of the logger is like a huge beetle. It swung its tentacles and immediately discovered the black crystal tree in the center of the base, so it rushed over without hesitation.

The next moment, the Beetle's body opened automatically, and its hard shell stretched out like a petal, revealing the extremely complex structure inside.

At the same time, various alchemy arms stretched out from the Beetle's body, like vines, wrapped around the black crystal tree.

After the whole process was over, the beetle-like "cutter" not only did not cut down the black crystal tree, but instead merged it with it, forming a huge building nearly ten meters high and like a lighthouse.

At the same time, in the Black Dragon Remnant Order in Midi's body, the number of harvesters also became 0.

Instead, it is a new device.

Black crystal steam spring, quantity

As the name suggests, this is a spring that will spew black crystal steam.

The black crystal tree is not a real tree, but a substance condensed by these steam. Now, while the harvester transforms the black crystal tree into a black crystal, he goes up to seal the spring directly.

This means that next, every bit of steam ejected from this spring will be collected by Midi and converted into black flame coins.

If the collection mode of "worker bees" is hunting, then there is no doubt that the Black Crystal Steam Spring is a model similar to planting.

There is no need to send out a collector or a guard. Of course, there will be no consumption generated during the collection process, and there will be no unknown or dangers that may be encountered in the wild.

Even if you don't have to do anything, just stay in this base and beside this black crystal steam spring, you will have a lot of black flame coins every moment, every minute and every second.

There is no need to mention rulers like Midi. Even Zaknavan and others who have never been in production, immediately understood the great benefits after seeing the effect of this steam spring.

If you can obtain enough steam springs or large enough steam springs, it will be an invincible place.

Even Midi didn't expect that there was such a secret hidden under the black crystal tree.

If he had known it, he wouldn't have waited for eight hours. Once he reached 1060 points in Black Flame Coins, he would go to the Dragon Temple to exchange it directly.

Looking back now, I am afraid that it is precisely because of the existence of this steam spring that the entire area, within a radius of dozens of kilometers, produces extremely dense black crystal plants.

However, it is not too late to discover this secret now, and you can definitely plunder it.

"Immediately, I'll get rid of the metal tiger and purple gold scorpion, and then wait until the new income reaches 1060, and then exchange it for the new 'cutter," Midi made the decision without hesitation.

Although neither of the two monsters are easy to mess with, and continuous combat will bring certain risks, at this moment, after seeing the benefits brought by this steam spring, no one objected to Midi.

While Midi and others were ready to be more important, the other three teams in the underground dragon tower were still moving forward.

The morale of the two-headed Wolf Warrior was very poor. They swept the entire fourth floor, but starting from the fifth floor and then to the sixth floor, they got nothing.

Along the way, there were all the damaged institutions and the remains of looting.

However, since the fourth floor is already relatively high, these are still expected by the two-headed wolf warriors.

The only thing they hope for at present is to preserve their physical strength as much as possible and reach below the tenth floor as soon as possible.

As for the red blood bat, the morale was relatively high. After all, there were no competitors on the fifth and sixth floors, and most of the spoils on these two floors fell into their pockets.

Saimen even made optimistic predictions, and it is very likely that their team is the deepest team, so there are only treasures and no enemies on the way forward.

But unfortunately, starting from the seventh floor, they were trapped in the same situation as the two-headed wolf warriors, and nothing else was seen except the ruins and exhausts.

As the saying goes, the higher the expectations, the greater the disappointment. Nowadays, the morale of the red-blooded bat is even lower than that of the two-headed wolf warrior.

Moreover, since it was inferred that the team ahead started exploring directly from the seventh level, the Red Blood Bats people could almost conclude that it must be the team of "King of Dou" Thor.

Following a level 6 strong man, no one will be able to relax.

Therefore, while being depressed and depressed, most of the people in the Red Blood Bat team increased their tension and anxiety.

However, if anyone is the most depressed, it is neither the two-headed warrior who has been mentally prepared, nor the red-blooded bat who is too optimistic and too pessimistic, but the scorpion of death

"The tenth floor...has it actually been explored?"
