However, after the test of many players, even if it is only the weakest protective shield, it can withstand the full onslaught of the second-order transcendent beast for about ten hours, which is completely enough for players to deploy troops to defend.

In addition to this safe zone, there are teleportation arrays in the player's town, which can be used to teleport from one town to another for a certain amount of in-game currency.

This is definitely good news for Guo Dafu, after all, now as his territory is getting bigger and bigger, the pressure on this defense is naturally greater, in order to ensure the safety of the territory, he can only continue to fight soldiers before, but fortunately, with the expansion of his territory, the places where he can be used for grazing and breeding and farming have expanded a lot, otherwise he really can't afford to raise so many soldiers.

And now with the appearance of this teleportation array, the pressure in this regard has been greatly reduced, and it is much easier to attack other beast kingdoms in the future, and you can use these teleportation arrays to quickly gather troops.

As for the game currency needed for this teleportation array, Guo Dafu also obtained a lot from the civilians under his command.

Before the rules of this game world were restored, all the divine power on it dissipated, and it became like scrap iron, and it was impossible to use at all, and even all kinds of transactions were carried out in Guo Dafu's territory, all in the form of barter, and no one used this kind of game currency.

But now that some of the rules have been restored and those teleportation arrays have appeared, this thing has finally come in handy.

So after Guo Dafu learned that the people under his command had these game coins in their hands, he used various materials and even elixirs to assist in cultivation to exchange them.

Then in just one day, Guo Dafu obtained the game currency worth more than 8 million gold coins.

There are three types of currencies on this ancient continent, which are copper, silver, and gold. Among them, gold coins are the most valuable, one gold coin is worth a hundred silver coins, and one silver coin is worth a hundred copper coins.

And what is very amazing is that these three currencies can be split and synthesized freely, so there is no need to worry about not being able to find change.

Guo Dafu tested it according to the instructions of those natives of the Xuangu Continent, and found that it was really as those people said, extremely magical.

When he used the split function on a gold coin, the gold coin immediately became a hundred silver coins, and then continued to split it into ten thousand copper coins, and finally he clicked twice to synthesize and turned back into a gold coin again.

Such a magical currency was not minted by a certain country, according to an old man like Qing Zhou, it was all given by the supreme creator god of the Xuangu Continent.

To obtain these coins, NPCs and players only need to sacrifice some valuable items to the creator god, and then they will be able to get the equivalent of these items.

Perhaps because of the peculiarity of these coins, these magical coins can be carried almost infinitely by players compared to other items, as they do not occupy the player's inventory at all, but only show a value.

Therefore, it is also very convenient to store these game coins, you don't need to put them in any bank, just find a few of your trusted subordinates to store them in batches.

For the time being, these game coins that have resumed their functions, Guo Dafu generally does not use them, and the points that are usually used are the points made by the Oranxing coalition government, after all, this thing can be exchanged for real coins at any time!

And those game coins can't be exchanged for real money for the time being, but due to the existence of those teleportation arrays, these game coins also need to be accumulated in your hand for emergency use.

In short, this revival of aura is a good thing for most people, except for that Dr. Zhang.

Because with the revival of the aura this time, more abyssal power was cleared from this world, causing some of the rules of this game world to be restored.

These changes in the rules have affected many of Dr. Zhang's experiments, and according to him, he was already on the verge of developing a recipe for gunpowder from the Xuangu Continent that was as powerful as black powder.

But because of this big change in the rules, most of his previous experiments were done in vain, and everything had to start all over again.

Guo Dafu didn't care too much about this, after all, he didn't expect that Dr. Zhang would be able to solve the problem that so many experts in the world had not solved.

What he wanted the other party to do the most was the mass production of the fierce beast black gold, and after asking, Dr. Zhang said that he had already solved this little problem.

In addition, in the process of dissecting and studying the corpses of the new breeds of fierce beasts that Guo Dafu got back before, he also found that these fierce beasts seemed to have their own attributes, and the bloodlines and organs of the same fierce beasts seemed to be transplanted.

Just like the Blood-billed Finch and the Evil Fire Crow, although they seem to be two completely different beasts, they seem to be both fire-attribute fierce beasts, so Dr. Zhang tried to transplant the transcendent organ in the body of those Evil Fire Crows that could make them breathe fire into the Blood-billed Sparrow.

The experiment was half successful, as the blood-billed finch that had been transplanted with the Evil Fire Raven's transcendent organ spewed out a mouthful of flames, and its body began to spontaneously combust, and then it was burned into a pile of charcoal in just a few minutes.

This result made Dr. Zhang realize that without the corresponding accessories, even if the extraordinary organs of other powerful beasts were transplanted to those weak beasts, those weak beasts would not be able to use them.

It's like forcing a cannonball inside a pistol, and pulling the trigger will not only not kill the enemy, but will blow yourself up.

So in order to solve this problem, he took the time to study it again during this time, and finally came up with a method that could completely transplant the Evil Fire Crow's transcendent bloodline into the body of the Blood-billed Sparrow.

And the blood-billed finch that he had successfully implanted with the extraordinary bloodline of the Evil Fire Crow was indeed as he expected, and its size began to grow rapidly, and its muscles, bones, and internal organs also began to be fully strengthened.

However, Dr. Zhang originally thought that the blood-billed finch would turn into an evil fire crow in the end, but in the end, it did not, but in this second-degree development process, some kind of mutation occurred.

Guo Dafu was also led by Dr. Zhang to see this blood-billed finch in his laboratory, which seemed to be still developing.

The original blood-billed finch only has the same strength as the steel-toothed rat in adulthood, and the wingspan is only about 60 centimeters at most.

The blood-billed finch in front of him, numbered ninety-seven, now has a wingspan of more than three meters, the feathers on his body have changed from the original gray-black to red like blood, and a pair of beaks are also made of fine red jade, reflecting a dazzling red luster. In addition, its tail feathers have become extraordinarily long, and at about three meters long, these tail feathers account for more than half.

The No. 97 test subject, which was transplanted with the blood of the Evil Fire Crow, has obviously improved a lot, and a pair of ruby-like translucent pupils are shining with wisdom, according to Dr. Zhang, this experiment is now able to complete a lot of more complex instructions, and the IQ is almost equivalent to that of a child of seven or eight years old.

As for the convenience of combat power that Guo Dafu is most concerned about, Dr. Zhang said that the combat power of the No. 97 test subject is roughly equivalent to that of a five-fold martial artist the day after tomorrow, but it can spit fireballs from its mouth.

Different from the pillar of fire spewed by the Evil Fire Crow, this Ninety-Seven test subject spits out fireballs the size of a fist, with a range of about two hundred meters, once it hits the target, it will produce a violent explosion, the power is equivalent to a high-explosive grenade, in Dr. Zhang's opinion, those martial artists below the innate realm, once hit by this fireball, will be seriously injured or even killed.

Guo Dafu is also very optimistic about Dr. Zhang's research, and decided to increase the investment of resources in the future, so that Dr. Zhang can research a transcendent bloodline transplant with a relatively high success rate, so that he can transform those blood-billed finches under his command and greatly improve the combat effectiveness of these blood-billed sparrows.

At the same time, he also asked Dr. Zhang to teach Zhao Jie the method of mass-producing ferocious beast alloy that he had researched, so that he could upgrade the steel plate armor of those ordinary soldiers into this armor made of ferocious beast alloy as soon as possible.

And while Guo Dafu and Dr. Zhang were discussing the focus of the next stage of research, the counterattack of the fierce beast kings who had taken refuge in the abyss on the Xuangu Continent had finally arrived.

If someone can come to a space millions of kilometers away from the Xuangu Continent, they can see that there is a huge fleet hovering above this continent.

The fleet consisted of thousands of warships, the smallest of which was tens of thousands of meters long, and on the periphery were a large number of frigates and cruisers armed to the teeth.

In the center, there are a large number of supply ships, most of these supply ships are filled with training pods, which contain clone warriors, some of which have been cultivated and are waiting for players to activate, and some are still in cultivation overload.

In addition, there are a large number of scientific researchers in some supply ships, studying and dissecting the corpses of fierce beasts.

The largest corpse, or skeleton, was a super giant beast skeleton that was more than 5,000 meters long.

In order to be able to place the skeleton of the giant beast, these researchers even specially modified a supply ship.

And in order to be able to participate in the study of the bones of this giant beast, many researchers can be said to have broken their heads.

Zhu Yuan was one of the lucky ones, and he was transferred to this research team three days ago to participate in the study of the bones of this giant beast.

After most of the day's work, Zhu Yuan also felt a little tired, so he asked the assistant robot to make him a cup of coffee, and then came to the porthole of the supply ship to watch the strange continent below.

This Xuangu Continent is not spherical, it is actually such a flat continent spread out, if you don't see it with your own eyes, no one will believe that there is such a strange continent in this world.

Although their expeditionary fleet has encountered many strange alien planets in the past, at least they are all circular planets like Oran! It is not a flat continent that violates science like the Xuangu Continent.

And just when Zhu Yuan had just drunk a cup of coffee, other colleagues behind him suddenly let out bursts of exclamations.

Zhu Yuan turned his head to look and found that it was actually the bones of the giant beast that had undergone a mutation.

I saw that on the surface of the giant beast's bones, I don't know when mysterious and complex purple-red lines appeared, and invisible fluctuations also spread out around this skeleton, one of the researchers retreated a little slower, and after being caught up by this fluctuation, his body actually floated under the gaze of everyone, as if he had come to the outside of the battleship, to the space where there was no gravity.
