Chapter 1821: No grass grows

Looking at the rock giants on the ground that were completely unkillable, the bone dragon also felt a headache, not knowing these "ghosts".
But after thinking about it, they gave up, because continuing to attack the rock giant would waste a lot of time, not worth it.
So in the next moment, they collectively flew to the second line of defense of the elves, preparing to continue advancing.
Other living undead creatures followed the bone dragon, and the undead lich used the corpses of the elven warriors to summon skeletons to prepare for the next wave of battle.
The road army who was still in the tree saw that the elf warrior had retreated, and was still close to annihilation of the entire army. He sighed deeply and climbed down from the eight-meter-high tree.
"They retreated. Only the rock giant survived, and there are more than two hundred bone dragons approaching us, prepare to fight." Lu Jun frowned and said to the people below.
"What? Defeated? But they only defended for less than an hour!" Hongyue, who was still consolidating the defense, was obviously surprised, as were the other black-robed men.
Although the elves beside them could not understand Lu Jun's words, they could feel the death of their companions, and they were all stunned.
The same applies to the elves managed by them on the left and right defense lines that are not part of the road army, but they are ready for battle and plan to meet the still running rock giants.
Although they know that they can't defend the bone dragon, fighting is their duty. As long as there is no retreat order, it is considered dead and they will stick to the line of defense.
"Well, those elves could have won, but the bone dragon suddenly appeared. The attack power was too terrifying. The elves were defeated in an instant." Lu Jun still had that expression.
"Then what should we do?! Ten thousand elves can't keep guarding for half an hour, so what are we guarding?!" There was a black-robed man on the left who was obviously excited.
Not because he was afraid, but because he couldn't see the hope of victory, so he felt a little broken.
The other black-robed people also knew the horror of the bone dragon, not to mention that more than two hundred came together, which made them equally desperate.
Only Hongyue and Lin Yilaan were watching Lu Jun quietly. They wanted to know if Lu Jun had a way to deal with it.
"Don't worry, I just noticed that these bone dragons are very densely located. As long as we can launch a wide range of attacks instantly, we can severely damage them. If the bone dragon is gone, the undead creatures on the ground have nothing to fear. "Lu Jun said while touching his scum.
Seeing Lu Jun's method, Hongyue's eyes suddenly brightened, because her lunar eclipse is a large-scale attack ability, plus Moonblade, as long as the timing is good enough, maybe it can really damage the bone dragon.
And because she took the Fountain of Life, her mental power has now been fully restored, and she can use a whole set of abilities to attack.
But before Hongyue had time to speak, Lu Jun shook his head directly: "You can't do it alone. There are more than two hundred bone dragons. Your ability can attack at most dozens. The remaining bone dragons can still be used. Kill us in an instant."
Listening to this, Hongyue's head slowly lowered. Indeed, her attack range is limited by herself...
"No, there are us, we can use combo abilities, endless thunder!" A man in black robes suddenly reminded Hongyue next to him.
After speaking, the other black-robed people also nodded at the same time. They did have a combination ability, and they had only used it to deal with Naga last time.
Although their current numbers are not enough, and the combined power of the combined abilities may not be enough, it is estimated that it will be no problem to deal with those bone dragons.
"What? Endless Sky Thunder? Combination ability?" Lu Jun's expression was a bit dazed, because he hadn't heard these terms.
And the final result is also obvious, these elven warriors failed to block the frost of the bone dragon, they were frozen one after another, and then shattered like glass slag, turning into pieces of corpses.
Even the undead creatures around the elven warriors were also affected, and they were also frozen together, because these frosts do not distinguish between enemy and us.
This is the attacking power of Tier S Bone Dragon. It is ruthless and devastating, and there is no room for people to struggle...
Only the thick-skinned rock giants and the elven warriors who were not within the range of frost escaped.
However, the bone dragon's attack did not end because of this. The next moment they collectively condensed a stream of frost and continued to attack the ground.
The coverage of this frost attack was larger than before, and nearly a third of the elf warriors died on the battlefield.
Faced with this level of casualties, the elf commander at the first line of defense was heartbroken, and immediately ordered the antler eagle and the druid of raptor who fled the battlefield to counterattack.
The antler eagle and the druid of the bird of prey naturally did the same, and went around to the back of the bone dragon from the left, intending to attack the bone dragon.
But the bone dragons seemed to have been alert for a long time, and the moment the staghorn eagle and the druid of the bird moved, they also moved.
The bone dragons immediately gave up attacking the ground, and turned back and spewed frost, covering the position of the antler eagle and the druid of raptor.
The antler eagle and the druid of the bird of prey obviously did not expect that the bone dragon would react so quickly, and they had no time to escape the frost and were frozen.
Although there are a lot of them, five times the number of bone dragons, in front of a sheet of frost, even if they are ten times more, they are useless, and they are all killed in a flash.
Seeing that their flying troops couldn't even get close to the bone dragon, the elf commander in charge of the first line of defense was shocked, no longer hesitating, and immediately let the elf at the first line of defense retreat.
After all, now they don't even have the only means of counterattack.
Hearing the retreat horn, the spirit of the surviving elves at the first line of defense was as gray as death, and his face dimmed in an instant.
Because they are very clear, the first line of defense on the south side is gone, and they have suffered heavy losses. This defensive battle is estimated to be extremely difficult.
But they didn't have time to think too much, and they didn't care about the corpses of their companions, and ran directly to the second line of defense, wanting to continue to intercept the undead creatures at the second line of defense.
However, how could a creature running on legs be faster than a flying bone dragon? The elf warriors who were fleeing, including the elf commander, were all killed.
In the end, only the rock giants can successfully escape, because they have resistant skin and can be immune to a lot of frost damage, but bone dragons can't help them.
As for them, as Tier S creatures, why don't they fight the bone dragon, because they don't have the slightest long-range attack ability and can only look at it from a distance.
This feeling of having a body of power but not being able to hit the enemy makes them very uncomfortable, but they have no alternative but to escape in despair.
