A level 40 bone dragon, that is the existence of the peak of the fourth order, although it may be for various reasons, it is nothing at all in Du You's eyes, and its strength is very weak. But anyway, this is also a powerful class that can be created by itself.

Sacrifice 100,000 Demon Flame Bones, which seems to be a lot, but the requirements for making Demon Flame Bones yourself are not very large, as long as you have a certain size, such as the size of a canine.

Besides, the 100,000 sacrifices did not say that they had to be of a high level, and they could only use low-level skeletons to sacrifice.

"The biggest benefit is not this, but the permanent existence, these bone dragons will not disappear because the owner leaves the world, but will always exist. ”

"But we have a fifth-order class, which of those soldiers is stronger than this bone dragon, it seems that this skill evolution is useless. Lin Yushi said with some disappointment.

"It's not useless, on the one hand, it's because the master's skills are already very strong, and they are high-star skills, and it's very difficult to improve. Lin Yucha analyzed and said, because Du You did not disclose his skill star rating, so the two sisters could not see the star column, and the two of them always thought that Du You was 9 stars like them.

"Most importantly, you guys haven't figured out the real use of this skill. This skill can be used in any world, and our soldiers can basically only enter and exit the world where the earth and the original territory are located. In other worlds, it's useless. Another thing is that these bone dragons are highly intelligent and can help us control skeletons in battle. ”

Du You remembered the time when he attacked the Quicksand Kingdom before, at that time, he directly released a large group of demon flame bones, allowing them to move freely according to their orders, if there was a bone dragon, the effect would definitely be better.

"I'll see, in this detailed introduction, there should be a hint to control the Demon Flame Skeleton. Wait, I found it, hey, I didn't expect it to have this effect. ”

Du You quickly said the details of what he saw: "The bone dragon can indeed help me control the Demon Flame Skeleton, at most one bone dragon can control a million skeletons. The most important thing is that under the control of the bone dragons, even if I leave this world, these bone dragons can ensure that these skeletons will not dissipate due to the loss of power. ”

Du You understands that this is completely the core of the army, and with this article, this change will not be a loss.

As Lin Yucha said, in those worlds that do not have their own territory, their own bone dragons can completely lead a large group of skeletons, and creating a large area is no different from their own large territory.

If there are more bone dragons, there are more skeletons, and even when you leave, it is not impossible for these skeletons to help you build a territory. Of course, Du You has not tried it, and he doesn't know.

"It's a pity, this is the world of giant beasts, and the opponent is too strong, even if you keep this thing, it is useless, but it is easy to attract attacks from natives or other professionals. ”

Although the bone dragon does not have a scourge cloud, who knows what trouble this skeleton will cause.

After the discussion, the three of them continued to stare at the battle outside. More and more demon insects and more and more dark beetles are still fighting, and the air seems to be entangled with each other, and there is never a time to stop.

This battle took longer than Du You imagined, from the beginning to the end, it lasted for five days.

Because of the suppression of the demon insects, although there are more and more beetles, they have never been able to grow like a snowball. Until the fourth day, because of the large number of demon insects died, more and more open space was left. At this time, his own dark beetles were finally able to snowball, and on the last day, the number of beetles increased.

In the end, the number of beetles in his own was almost a thousand times that of the remaining demon insects, and the number was constantly increasing. Because there are still many bugs around, they can provide a large amount of food for the dark beetles, so that the dark beetles will become more and more.

With the numbers, the dark beetle finally took the initiative to surround the sixth-order demon insect group, and then attacked.

Using the method of accumulation of numbers, in the end, those sixth-order beetle teams were eliminated one by one. Although some rebellions were launched during this period, it was useless, and Du You, the initiator, was never found.

Of course, the demon beetle is not a vegetarian, and in the process, the mother worm of the dark beetle has been killed I don't know how many times. But what the demon insects don't understand is why this female insect just can't be killed.

The demon worm doesn't know that every time he kills the opponent's mother worm, the opponent will change places and reconstruct a mother worm to come out. When the demon worm found out, I don't know how much the other party's beetles have increased.

When the fourth sixth-order group was wiped out, the second piece of Worm King Jade was finally created. When Du You fused with the Insect King Jade, the battle between the beetle and the demon insect had already come to an end.

The fifth and last sixth-order team was quickly wiped out, but at this time, Du You was not given the third insect king powder. His own explosion rate is so low, obviously it is not very likely that others want to get the Worm King Jade at all. Maybe the previous team came just to try their luck and killed themselves.

The battle ended very quickly, and after there was no Sixth Order and most of the Fifth Order groups were wiped out, the remaining demon insects couldn't last long at all. The destruction of the demon insect is faster than the dissipation of the calamity cloud in the sky.

At the last moment, Du You summoned the Scourge Giant Dog, let the Disaster Giant Dog run over, absorb some of the Scourge Clouds that have not yet dispersed, and improve his own heritage, which is better than nothing.

In order to prevent the demon worm from reappearing, Du You let his dark beetle clean up the entire land. Within the scope of the entire Demon Insect Disaster, in the end, not a single insect was left, and even dug three feet into the ground to destroy all the eggs.

After doing all this, Du You looked at Lin Yushi, who had already improved his skills with Worm King Jade at this time.

Needless to say, it must be the skill of Demon Slayer. Because Lin Yushi's skills are 9 stars, and the power effect is not as strong as his own, the change should be greater than his own, but he doesn't know how much benefit he has to himself.

Skill mutations, especially this kind of mutations that have no way to determine the direction, who knows what the final result will be, this kind of thing can only rely on luck. But looking at Lin Yushi's gradually revealing smile, Du You understood that the effect this time might not be bad.
