Over the next eight hours, the speed of black crystal's collection produced an astonishing, yet unexpected, increase.

The black crystal worth 34,000 black flame coins was directly collected by 17 worker bees, and the average contribution of one within eight hours was 2,000 points, which is equivalent to 20 black crystal grasses or 5 black crystal flowers.

This is also the result of the fact that the black crystal trees could not be harvested.

However, at the same time, these worker bees have finally begun to show losses.

After all, under every black crystal vine, there is a poisonous snake or other magical beast guarding it, and if the worker bees want to seize the source of energy they rely on for survival, they will naturally encounter the heaviest counterattack.

Although Midi and the others launched a clean-up campaign as soon as they started, trying to clean up all the demonic beasts attached to the Black Crystal Vine, after all, there were only four of them.

Not every monster will be killed with a single blow, at least many will escape.

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

Once the fleeing beast returns, the retaliatory attack will become more and more ferocious.

And if the worker bees directly find a black crystal vine that Midi and the others didn't find at all, they will undoubtedly be directly attacked by the shocked demonic beasts.

After eight hours, the loss of 17 worker bees reached nearly 50%, and a full 8 worker bees were destroyed, and one of them was stopped on the way back with a large number of black crystal plants.

If all of them are intact, perhaps, the output of black crystal can directly exceed 40,000 points.

"We have already explored within a radius of more than 100 kilometers, and if we explore further, I'm afraid that too much time will be wasted for the four of us. These worker bees can no longer be collected in such a fragile way. Besides, it's almost time to make a move on this Sombra tree. Midi made a decision.

Carrying 34,000 Black Flame Coins, Midi came to the Dragon Temple again, but compared to the previous two times, this time he seemed much more confident.

"It's a good job to be able to accumulate more than 30,000 Black Flame Coins in a short period of time. The dragon head glanced at Midi and showed a slightly surprised expression, "This time, what do you want to exchange?"

Since the entire list of low-level huàn is open, although Midi only used the two devices of "worker bee" and "honeypot" at the beginning, in fact, in the past two days, he has actually been thinking about what kind of development route is the most suitable for him next.

Now that he was here, of course, Midi had repeatedly considered and calculated in his heart, and as soon as the light curtain in front of him unfolded, he immediately chose a few new devices without hesitation.

First of all, there is the high-grade Black Crystal Collector "Harvester" worth 10,000 Black Flame Coins.

This is a collector capable of harvesting black crystal trees.

Despite the fact that the price was a full twenty times more expensive than the worker bee, Midi gritted her teeth and did not hesitate to take it down.

Because he knows very well that if he is to occupy a leading position in the resource war, worker bees alone are not enough.

That kind of lowest-level alchemy puppet may make people feel cheap and cost-effective in the early stage, but with the increasing number and increasing damage rate, coupled with low efficiency, difficult management, etc., all aspects of the problem are enough to make the price advantage completely meaningless.

Worker bees can only be used in this early stage, and one day in the future, when it reaches a certain stage, Midi will definitely abandon all worker bees.

That's why he gave a "Harvester" in order to prepare for future development.

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

However, while he produced a large number of worker bees with huàn, he also exchanged another kind of alchemy puppet with huàn.

A guard puppet "Soldier Bee" worth 1,500 Black Flame Coins.

The worker bees and the soldier bees make up for each other, which can undoubtedly greatly reduce the loss rate, otherwise, after the initial rollout, the loss of the worker bees themselves alone is enough for Midi to drink a pot.

The last device used by Midi to Huàn is another alchemy puppet "Flying Eye" worth 3,000 Black Flame Coins.

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

It can be said that this is a multifunctional alchemy puppet.

The "flying eyes" are designed to allow them to take their place and explore a radius of 100 kilometers.

Don't look at the area where the three black crystal trees are located at this stage, Midi can't eat it, but Midi can predict that after the other teams also enter this black crystal forest and start a competition for resources, this war will definitely not start in such a small area.

If the Black Crystal Forest is only such a small size, let alone the True Dragon Forging Body Method worth 1 million yuan, it is a mid-level list of Huàn, I am afraid it will not be able to open.

Since the setting value of the high-level list is 1 million, with this number alone, Midi can imagine that the area of this Black Crystal Forest is definitely not smaller than the Gran Forest next to the Belmar Kingdom.

Only an area as large as a small country can afford to fight a war for resources.

After returning to the base, Midi immediately released all the worker bees, soldier bees, and several expensive flying eyes that came to Huàn, and continued to gather resources non-stop.

At the same time, the "Harvester", which was worth 10,000 Black Flame Coins and was more than five meters high, was also released at the same time.

The harvester, shaped like a giant beetle, swung its tentacles and immediately spotted the black crystal tree in the center of the base, and rushed over without hesitation.

The next moment, the beetle's body unexpectedly opened automatically, and the hard shell stretched out like petals, revealing an extremely complex structure inside.

At the same time, all kinds of alchemy arms stretched out from the body of the beetle, like vines, entangled in the black crystal tree.

When the whole process was over, instead of cutting down the black crystal tree, the beetle-like "feller" merged with it to form a huge structure nearly ten meters high, like a lighthouse!

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

In its place, a new device was created.

Black Crystal Steam Spring, Qty 1.

As the name suggests, this is a type of spring that spews out black crystal steam.

The Sombra Tree is not really a tree, but a substance condensed by the steam, and now, the loggers are turning the Sombra tree into Sombra while they themselves go up and seal the springs.

This means that next, every breath of steam that ejects from this fountain will be collected by Midi and converted into Black Flame Coins.

If the gathering mode of the "worker bees" is hunting, then there is no doubt that the black crystal steam spring is a pattern similar to planting.

There is no need to send collectors, no guardians, and of course, there will be no consumption during the collection process, let alone all the unknowns or dangers that may be encountered in the wild.

You don't even have to do anything, as long as you stay in this base and stay next to this black crystal steam spring, you will have a lot of Black Flame Coins coming in every moment and every second!

Needless to say, rulers like Midi, even Zaknavan and others, who had never been in production, were immediately able to understand the great benefits of this steam fountain after seeing its effects.

If you can get enough steam springs, or steam springs large enough, you are invincible!

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

If he had known earlier, he wouldn't have waited for even eight hours, and once he reached 10,000 Black Flame Coins, he would have gone directly to the Dragon Temple to redeem huàn.

Looking back now, I am afraid that it is precisely because of the storage of this steam spring that the entire area, within a radius of tens of kilometers, will produce the phenomenon of extremely dense black crystal plants.

However, it's not too late to discover this secret, and it can definitely be plundered.

"Go and kill the metal tiger and the purple golden scorpion immediately, and then wait until the new income reaches 10,000, and then immediately go to the new 'Harvester'!" Midi made a decision without hesitation.

Although those two demonic beasts were not easy opponents to mess with, and continuous combat would bring certain risks, but at this moment, after seeing the benefits brought by this steam spring, no one objected to Midi at all.

And while Midi and the others were gearing up to do a big job, in the underground dragon tower, the other three teams were still advancing.

The morale of the two-headed wolf was very poor, they swept the entire fourth layer, but from the fifth layer and then to the sixth, they got nothing.

Along the way, the path is full of destroyed mechanisms and looted ruins.

However, since the fourth layer was originally relatively high, these benefits were still expected by the two-headed wolf fighters.

The only thing they want at the moment is to preserve the body as much as possible, and reach the bottom of the tenth floor as much as possible.

As for the red-blooded bats, their morale was originally relatively high, after all, there were no competitors in the fifth and sixth layers, and most of the loot in these two layers also fell into their pockets.

Simon even made an optimistic prediction that most likely, their team is the deepest team, so there are only treasures and no enemies on the road ahead.

But it's a pity that from the seventh layer onwards, they are stuck in the same situation as the two-headed wolf warrior, and they can't see anything but ruins and exhaust gas.

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

Moreover, since they deduced that the team in front of them was exploring directly from the seventh layer, the people of the Red Blood Bat could almost conclude that it must be the team of the "Fighting King" Thor.

Following a level 67 powerhouse, no matter who it is, it will not be easy.

So, in addition to being depressed and depressed, most of the people in the Red Blood Bat team added tension and uneasiness.

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

"The tenth floor...... It's already been explored?"

So far, Thor, the "Fighting King" who has been calm and breezy, finally frowned, and a cold color flashed in his eyes.
