Suddenly, there was a low roar on the ground, followed by the sound of rolling at any moment.

Xuanyu, who was guarding the city wall, immediately fought, looking at the distance and stunned.

Under the alien beast that was shot to death, a deep pit five or six meters wide had already appeared, and only a black shadow flashed.

The strange beast that was nailed to the ground by a crossbow arrow more than two meters long also disappeared in an instant, leaving only a large pit in the ground.

Even Xuanyu hadn't discovered how that black shadow had brought the corpse of the alien beast into the cave.

However, the fear of this pit filled Xuanyu's heart in an instant.

In order to defend against the alien beast race, Qingqing had ordered to build another city wall in a place where there was no lapis lazuli slab.

But I don't know why, there are potholes on the ground, and everyone who falls into it has not come out again, and even the elite team sent in to investigate is exactly the same, and no news has come out.

Later, Qingqing had no choice, but only ordered them to retreat into the line of defense covered by lapis lazuli, so that no potholes appeared again.

However, today, that terrible pit has reappeared.

This kind of scene, how could it not shock Xuanyu, but what happened after that finally made him know what those pits were.

As the first potholes appeared, it was as if there was a chain reaction, and countless potholes appeared on the plains outside the defensive line.

Perhaps because the defense line was covered with lapis lazuli slabs, there were no potholes.

But even though it was still three or four thousand meters from the plain, it was enough to see the countless craters that were dense enough to make people with dense phobias faint.

Xuanyu still felt a chill in his heart, and the eight or nine hundred thousand foreign beasts above the pit felt different.

Since the alien beasts were only ordered to guard the city gates, they occasionally harassed the soldiers of the central defense line.

So discipline is lax, of course. Even if it is strictly forbidden, the alien beasts still have to do what they should do, and it is they who are unorganized and undisciplined.

It is precisely because of this that eight or nine hundred thousand strange beasts did not gather in one place, but were distributed over a land of hundreds of kilometers.

It was also because of this that when countless pits appeared, not many strange beasts fell into the pits, but it also alerted the Beast Emperor, after all, when the pit appeared at the beginning, there was still a black shadow.

Dragged the carcass of the beast directly into the pit. Therefore, not only the alien beasts, but also the humans were staring closely at the pits, trying to see what the black shadow that had just appeared was.

However, before their eyes could turn, even many strange beasts were still stunned for a moment, and countless black shadows appeared from the pits, each of them. Except for those that fell in, black shadows appeared.

Directly rolled up the strange beast at the edge of the pit and brought it into the pit.

However, perhaps it is because hunger does not choose food. A black shadow actually rushed directly towards a beast emperor standing at the edge of the pit, maybe for an ordinary beast.

These dark shadows were too fast to be seen, but they were still too slow for the Beast Emperor.

The claws are lightly raised. He pressed a dark shadow under his claws.

It was only then that people saw what those dark shadows were, which was a thick tree root. However, there are many transparent barbs on the roots of the tree, which can be clearly seen that the barbs are actually hollow.

Roots?

Xuanyu was stunned, it turned out that it was the root whiskers that had been attacking them, so it could also be explained why it came out of the ground.

The defense line is covered with lapis lazuli slabs, and there are all kinds of powerful magic circles carved on it, so these tree roots cannot break through the ground and enter the defense line.

If there were no such lapis lazuli floors in the defense line, Xuanyu was just stunned and threw out the terrible thought in his mind.

At this time, some of the roots of the trees had been pressed to the ground by the powerful beasts in it, but their skin was not as hard as that of the Beast Emperor.

In just an instant, the strange beasts that pressed the roots of the tree to the ground instantly jumped up with a wail, and waved their claws vigorously, trying to throw out the roots on their claws.

But the roots of the trees seemed to have heels on their claws, and no matter how hard the beasts tried, they were firmly attached to their claws.

Xuanyu could even see that the barbs on the root of the tree had been pierced into the claws of the alien beast, and through the transparent exterior, the hollow pipe inside was constantly pumping blood into it.

Those barbs turned out to be for bloodsucking!

Xuanyu felt a chill all over his body for a moment, and couldn't help but be glad that he didn't go when he was building the city wall, otherwise he would be pierced into his body by those roots full of blood-sucking barbs.

Xuanyu didn't think about the rest of the matter, just thought about it for a while, and felt a cool breeze blowing through his body.

The alien beast that was entangled in the roots of the tree soon turned into a dried corpse, not only the blood, but also the flesh and blood essence were the same, and they were directly sucked away.

Ken Kuai, one by one, seven or eight meters tall, turned into a pile of dust, blown by the wind, scattered all over the ground.

However, more alien beasts were dragged directly into the pit, and only by listening to the wails coming from the pit knew what was going on inside.

After being stunned for a moment, Xuanyu had to come up with a guess that made him feel frightened, the entire underground of the central defense line had been entangled by these unknown tree roots.

However, because the ground in the central defense line is made of lapis lazuli, and countless magic circles are depicted, these roots are also helpless.

And the alien beasts around the defense line have also reached the point of great mold, so why there are fewer and fewer alien beast corpses in the outer defense line has an answer.

It must have been these tree roots that drained all the flesh and blood essence from the alien beast's body and turned it into a pile of useless powder, so the corpses naturally decreased.

Thinking of this, Xuanyu immediately became clever and said to a soldier next to him: "I have something to report, you keep this well." ”

In fact, Xuanyu was purely worried, not to mention that these strange beasts were being attacked by the roots of the tree now, even in normal times, the time required for them to break through this city wall was enough for the city defense army to run back and forth three times.

The soldier nodded, and then Xuanyu directly turned into an afterimage and ran towards the command post, the central defense line was more than three hundred kilometers long and fifty miles wide.

Therefore, the command post is a little far away from here, with twenty skills, but for Xuanyu, it is only a matter of two minutes.

With the blood-sucking barbs, all the nutrients in the body of the alien beast were extracted, and along the roots of the tree, it was continuously transported like a strange, magnificent underground space. (To be continued......)
