Mikako and Rikako, at the foot of Yanshi Mountain, looked up, looking nervous and worried.

Under the moonlight, on the top of Yanshi Mountain, a large black mist suddenly rose, and immediately after, countless arrows rose from all directions, shooting towards the 'hill' shrouded in black mist.

On closer inspection, these arrows are grayish-white, and the surface is as smooth as jade, and even gives people the feeling of jade arrows.

In the rain of arrows in the sky, there are a batch of arrows that fly a little faster, more dazzling, not only the material is more similar to the white jade, but also at the front end of the arrows, there is also a little white light, which is obviously the effect of the 'sniper' skill.

Of course, in the eyes of Mikako and Rikako, they can only see black mist and arrows as thin as the tip of a needle, and they can't see a clearer picture.

Chu Chen took Lin Manyue and hid on the mountainside of Yanshi Mountain, hiding behind a boulder, commanding the bone dragons and skeletons to fight against the Hydra clone.

This time, the battle target was too strong, and the disparity between the strength of the enemy and the enemy was too great, so Chu Chen did not dare to directly participate in the battle, resulting in skills such as 'damage amplification' and 'speed enchantment', which could not be used.

Suddenly attacked, several giant snake heads exposed outside the crater quickly shrank and hid back inside the volcano, leaving only the snake head who was proficient in water and ice, as if afraid of the high temperature inside the volcano, still remained outside the crater.

Chu Chen was overjoyed when he saw this, and hurriedly commanded the bone dragon and skeleton archers, and quickly launched an attack on them, making the snake head, who was already weak, even more wailing and miserable.

"Hiss~!"

The cries of snakes are generally not too loud, but this sound made Chu Chen on the mountainside feel a little roaring.

With this roar, a huge snake head rushed out of the crater and shot straight towards the bone dragon in mid-air, and the naked snake body actually reached nearly a hundred meters.

The bone dragon can fly hundreds of meters in the air, and even if Chu Chen deliberately commands it, it is not impossible to reach an altitude of more than a thousand meters.

But at this time, it was necessary to attack the hydra clone, and the bone dragon naturally couldn't fly very high, so it was only for a moment that it was bitten by the huge snake head.

The hydra clone bit the bone dragon and threw it violently, bending the snake's neck into an inverted 'U' shape, and at the same time, throwing the bone dragon near the crater.

"Bang~!"

The sound of the bone dragon falling into the crater was like a signal to several other hydra clones, and in an instant, the other six hydra clones rushed out of the volcano, either directly using their huge snake mouths, or standing up snake bodies, and constantly throwing all kinds of magic at the bone dragon.

In just over two minutes, the bone dragon that was firmly trapped was scattered by these hydras.

Seeing this scene, Chu Chen's face turned pale, and the surprise, fear, hesitation, and firmness in his eyes flashed alternately.

As if noticing the firmness on Chu Chen's face and the last show, Lin Manyue on the side quietly hid her figure.

In his heart, he commanded the remaining bone dragon, flying quickly around the eight hydra clones in the sky above Yanshi Mountain, and sometimes throwing a few 'curse' skills at those hydra clones.

Chu Chen's purpose in letting the bone dragon do this was to attract the attention of the eight hydra clones, so that the skeleton archers could continue to attack the hydra clones who had fallen into a weakened state.

The hydra clone, due to its unfavorable development and staying in the crater for a long time, fell into a weakened state, and its health was only in its early 1,000s.

It has been attacked by the skeleton archers for a while, and it has been in the range of 'covering the sky', so there must not be much health left, and it is likely to be shot by the skeleton archers!

And these hydra clones, although they all have their own thoughts, they don't have much ability to think and reason.

For them, the damage dealt by these skeletons was very limited compared to the Bone Dragon, so they kept trying to attack the Bone Dragon, ignoring the Skeleton Archers for the time being.

Looking at the top of the mountain, the magic of various systems was constantly released by the hydra clone, Chu Chen was very happy, if he was also on the top of the mountain, even if they didn't notice him, I am afraid that they would be affected by some large-scale magic.

After four or five minutes of stalemate, the effect of 'obscuring the sky' disappeared as there was no bone dragon to maintain.

The hydra clone trapped in the black fog screamed a few times as soon as it showed its shape, attracting the attention of its companions.

The head and neck of this hydra were densely covered with bone arrows, and dark red blood flowed everywhere, and it seemed to have a corrosive effect, dripping on the ground, melting out not too small holes.

You must know that these eight hydra clones are not one for the time being, and once this doppelganger dies, they are one step backwards from becoming a real hydra.

"Hiss~!"

The Hydra clone who had comprehended the forbidden spell roared, and then the eight Hydras began to perform different tasks.

The hydra clone who is proficient in the fire system, with a hydra clone who is proficient in the wind system and a hydra clone who is proficient in the dark system, continues to attack the bone dragon.

The other Hydra clone, who is proficient in the wind system and the dark system, turns the snake's head and begins to deal with the skeleton archers around it.

There are still three hydra clones left who are proficient in water, ice, earth, and wood.

Among them, the wood-based hydra clone began to release healing spells, preparing to heal the severely injured hydra clone of the water and ice systems.

And the hydra clone who was proficient in the earth system actually began to release defensive magic, and built a circle of earth walls around the eight hydra clones to block most of the bone arrows.

"Bang!"

Seeing this scene, Chu Chen frowned and slammed his fist on the boulder in front of him.

Originally, in Chu Chen's plan, he was going to take advantage of the seriously injured hydra clone to enter a near-death state, and the skeleton archer led to release a 'sniper' and kill it in one fell swoop!

But now, it seems unlikely.

Chu Chen's mind was spinning rapidly, and he quickly formulated plans one by one according to the situation in front of him, but he was vetoed one by one.

In the end, Chu Chen gritted his teeth and directly ordered the bone dragon to turn around, fly away from the battlefield, hide a few hundred meters away, and start chanting.

Without the containment of the bone dragon, the hydra clones began to crawl out, and while crawling towards the bone dragon, they also crushed a lot of skeletons along the way.

Dozens of seconds later, the bone dragon's chanting stopped, and around the badly injured hydra, a large amount of black mist appeared again, and then, the bone dragon began to chant again.

Let the bone dragon release the 'black curtain covering the sky', not that Chu Chen wants to rely on this skill to kill the hydra clone, but he needs to rely on this skill to lower the blood line of the hydra clone, if it is allowed to restore its health, then the bone dragon and skeleton that Chu Chen sacrificed before will all be wasted.

Next, what Chu Chen let the bone dragon release was the skill of 'summoning hellhounds', the purpose of which was to deal with those earth-based defensive magic, so that the skeleton archers could continue to attack the seriously injured hydra clone.

This 'summoning hellhound' skill, Chu Chen rarely let the bone dragon release.

Although this skill is not too weak, firstly, Chu Chen himself has a lot of skeletons, and secondly, the hellhounds summoned by this skill, Chu Chen cannot directly command, so he can only give some simple orders to the bone dragon, and then the bone dragon will order the hellhound.

For an undead creature like a bone dragon, it is not easy for him to have excellent fighting instincts, and it is difficult for some strong dragons to let it command the hellhound to fight.

However, at the moment, the differentiated bone dragon has been scattered, and after the bone dragon is summoned, except for the moment when it can be differentiated, after that, it will not be able to carry out the differentiation operation.

The remaining bone dragon has no way to complete the tasks of containing the Hydra clone and destroying the 'earth wall' and other defensive magic tasks at the same time.

In desperation, Chu Chen could only take a risk, let the bone dragon contain the hydra clone, and at the same time, ask it to command the hellhound and destroy the 'earth wall' and other defensive magic.
