All the troops that entered the Dragon Country this time, under the command of the Dragon Traveling World, swept down the slope from above the deep valley like an avalanche.

"Roar!!"

Countless dragon creatures that had not entered a state of slumber because of their low rank were alarmed by the sudden invasion of the Xia Kingdom and surrounded them from all directions.

In fact, if it weren't for the fact that there was only one dragon sleeping incense, and it lasted only six hours, Long Xing Tianxia would not be willing to make such a big move, but would find a way to lure away these dragon creatures who were not sleeping.

But Long Mianxiang only has six hours of mission time, once there is no Dragon Mianxiang and a large number of high-level creatures into a state of sleep, this Dragon Country mission is impossible to complete at this time period, but it will take an unknown amount of time to complete.

In other words, the task of this Dragon Country, if the task is completed within the six hours of the dragon sleeping incense burning, the difficulty is epic, or the kind of epic task that is also the easiest epic task among epic tasks, but once it exceeds six hours, the difficulty will immediately soar to the difficulty of the legendary task.

Xu Yun led Bai Xiaosheng and the five of them, and together with the players of his giant power, they rushed forward behind the dragon world, and the dragon creatures in front of them who were rushing towards them did not need their help, and their only task was to kill 10 seventh-order ancient dragons in six hours.

"Leader, there's a first-order water system ancient dragon over there! , coordinates are ***.***", the reverse scale who went out to reconnoiter appeared next to Long Xingtianxia, and I don't know how he managed to come and go freely in such a place densely populated with dragon creatures without being discovered.

"The whole army is moving towards ***.***, according to the plan!" , Hearing the appearance of the first prey, I immediately commanded the troops to rush towards the target, and since the dragon sleeping incense was in effect, he also used the amplification scroll to command the team, so that it would not have to be conveyed to others layer by layer. It can improve the efficiency of the command a lot.

If you look over the deep valley, you will find that the wave formed by dense black dots suddenly rushed towards a lake in front of the side, and the siege of a large number of dragon creatures along the way could not pose any obstacle in the face of this high-level army that needs to be calculated in tens of thousands.

Ten minutes later, on the edge of a circular lake with a radius of several hundred meters.

Looking at the calm and clear water in front of him, Xu Yun faintly saw what creatures were sleeping at the bottom of the lake, and he didn't know how the assassin named Reverse Scale found the other party.

"Can the smell of dragon sleep incense even be conveyed under the water?" , Looking at the ancient dragon at the bottom of the lake that was about the same size as the seventh-order black dragon, even if he was surrounded by them, he didn't react, Xu Yun couldn't help but be secretly surprised, he didn't expect that even the ancient dragon sleeping at the bottom of the lake had entered a deep sleep state because of the influence of the dragon sleeping incense.

At this time, other top and large forces were laying defensive lines on the periphery of the lake, struggling to resist the siege of those dragon creatures who had not entered the deep sleep, but the dragon world had no intention of letting Xu Yun and them attack immediately.

"Shackles of War!!" Just when some players couldn't hold back and wanted to ask why Long Xingtian didn't do it yet, a cold female voice came into the ears of all players, and a transparent light mask expanded rapidly.

Turning his head to look, Xu Yun found that in the Dragon Mercenary Group, the woman who had previously used the third-order battle magic Ice Demon Ring to deliver an extremely terrifying blow took out a silver-white shackle-like item, and the transparent light curtain was emitted from that shackle.

"Before the Qingyin magic power is consumed, no one and creature can escape from this layer of light curtain, so we don't have to worry that this sixth-order ancient dragon will escape, but we have to move quickly, as soon as there is no magic enchantment created by the shackles of war, the ancient dragon will definitely flee immediately, and with the magic power of Qingyin, it should only last about ten minutes, do it!"

Long Xingtianxia explained to everyone the function of this light curtain, and at the same time ordered to do it.

"Brush!!"

Those nearly 100 carriages that were protected by the Dragon Mercenary Group in the center of the team, covered with black cloth, were torn off by the players of the Dragon Mercenary Group at this time.

"This!!" , something that surprised Xu Yun appeared in front of him, because these things not only did he know, but also had a 'profound' image.

Nearly a hundred five-meter-long giant crossbows appeared on the carriage in the center of the Dragon Mercenary Regiment, and the crossbow arrows that shimmered with cold light on them spoke of the brutality of these weapons.

Xu Yun looked at these bed crossbows, that time when he was in the green wind plane, the memory of being almost killed by the elves in that city with bed crossbows came to his heart, if he remembered correctly, the range of these bed crossbows should be 300 meters, but I don't know if there is that kind of enchanted special crossbow arrows in the dragon world.

When the players of the Dragon Mercenary Group adjusted the direction of the crossbow arrows, a seventh-order Titan giant more than ten meters tall condensed a thunderbolt spear in his hand, and then threw it fiercely at the seventh-order water system ancient dragon at the bottom of the lake.

"Boom!"

A violent explosion sounded, and the thunderbolt spear ignored the obstacles of the lake and hit the target sleeping at the bottom of the lake, exploding a column of water dozens of meters high.

The water of the lake fluctuates violently.

"Roar!!"

With a loud roar, a large blue figure rushed out from the bottom of the lake.

"Ranged troop attack!" , Long Xingtian gave a loud order, now is the time for the long-range troops to fire!

The first to fire were the hundreds of bed crossbows.

"Bang!!"

"Bang!!"

"Bang!!"

Hundreds of one-meter-long crossbow arrows, with the momentum that can penetrate even air, one-third of them hit the seventh-order water system ancient dragon that was flying into the distance, and in the face of such a high-speed flying class, the attack of the long-range troops was not 100% hit.

"Poof!"

"Poof!"

"Poof!"

……

Dozens of one-meter-long crossbow arrows pierced the blue ancient dragon's body deeply, and a large amount of blood spilled from mid-air.

"Roar!!"

A tragic roar came from Gu Long's mouth, and even if Xu Yun and the others couldn't see the specific damage number of the bed crossbows, they knew just by listening to this scream that the damage caused by these bed crossbows was definitely not small.

Although the ancient dragon that was hit by dozens of huge crossbow arrows let out a roar, it did not mean to turn back, but still flew in the direction away from them.

At this time, the other high-level units and the ranged units of the three legions also opened fire at the same time.

Corpse witches, monks, cyclops...... The archers and wood elves of the three legions also fired at the same time, and the ranged pros of the dragon mercenary group also attacked, as if the rain of arrows and various attacks that could obscure the sky drowned out the ancient dragons of the water system.

As all the ranged attacks were about to hit, a curtain of blue water enveloped the ancient dragon's massive body.

A few seconds later, looking at the blue figure still flapping its wide wings away, everyone had mixed feelings, because this wave of attacks, which combined all the long-range firepower, seemed to be less damaging than those bed crossbows.

"Prepare for battle, all seventh-order flying classes pay attention to cooperate and cover!" , Long Xingtianxia spoke out at the right time to pull everyone's energy back.

Five hundred meters of the sky in the distance.

"Bump!"

A loud bang came out, and I saw that the hideous head of the seventh-order water system ancient dragon seemed to hit the invisible wall.

Flapping its wings behind it and hovering in mid-air and shaking its head, the vertical pupils in the ancient dragon's eyes seemed to be dyed with a layer of blue light, and it saw the enchantment created by this shackle of war.
