Under the detection of Ye Feng's spiritual power, the monsters hidden underneath the ground were removed, and the total number of monsters that appeared in front of him at this time was 42, of which the number of giant rats was nearly 27.

It's just that whether it's giant rats or mutated pythons, sandworms and other monsters, they are all helpless to take the dragons flying in the air, so then, they are also surging straight towards the summoned beasts stationed at the entrance level.

At this moment, a ball of golden-red flames suddenly shot towards the monsters, which was his Dragon Flame Breath Ability!

In the violent explosion, I saw that the body of one of the giant rats was suddenly engulfed by flames, but what was surprising was that the scorching flames did not burn the hairs on its body together, and under the burning of the flames, the hairs on its body actually exuded a luster as hard as metal!

With such a level of defense, it really deserves to be a variant of the G virus!

At this time, I saw an ice spear exuding bursts of frost aura suddenly shooting out of the air, and there was a soft sound of "ding"!

This hard ice spear was actually ejected by the hard hairs on the giant mouse's body, and the hairs on its body were simply comparable to the hardness of iron armor.

However, what really shocked Yefeng was that when the giant rats rushed to a few dozen meters in front of the defense line formed by the alien army, they suddenly stopped, and then their fur stood on end.

Then, with a bang, dozens of black shadows shot over as quickly as arrows from the string.

The sound of "fluttering" rang out endlessly, and I saw that these dozens of black shadows easily pierced the bodies of the alien soldiers, and some of them shot into the earthen wall behind the defense line, and then actually went directly through the wall, leaving only a hole as thick as a cup!

If you look closely, it is the hair on these giant rats that is responsible for all this, and they shoot out their hair like crossbow arrows, and its power is definitely not inferior to that of bed crossbows and the like.

Fortunately, this kind of hair piercing power is so amazing, but because of this, the damage area it causes is limited, so for summoned beasts, as long as the head and heart and other vital parts are not pierced, then at most it is only injured and not killed.

And the range of only a few dozen meters at most may be their only weak point, and the range will be reduced even more if they shoot from the top, which is probably why they don't shoot at the night blade flying in the air.

It is worth mentioning that although the shooting ability of giant rats is limited because it relies on the hair on its body as ammunition, the amount of ammunition is also limited, but what you need to know is, how much hair is on a mouse?

Visually estimated, there are at least hundreds!

Of course, for giant rats, this hair is as hard as iron, so it certainly doesn't grow as fast as normal hair, which basically grows in a month's time.

Therefore, unless they encounter a life and death crisis, they will not use all the hair on their bodies here, after all, once there is no such hard as iron hair attack and defense, then these rats will lose their dependence on survival in this underground world.

But despite this, these giant rats are also the most threatening monsters for summoned beasts at the moment.

Because they are monsters with ranged attack capabilities!

Under the shot of hairs like crossbow arrows, the army of summoned beasts under the command of Ye Feng also suffered casualties in an instant, 4 alien soldiers died, and nearly ten alien soldiers had different numbers of penetrating wounds.

However, it is worth mentioning the dozen or so skeleton warriors, because their bodies have long been devoid of flesh and blood, only a pair of white bones remain, and in the middle of the white bones, it is completely hollowed.

Therefore, most of the hairy crossbow arrows that were shot into the skeleton warrior's body actually penetrated directly through the gaps between the bones, and a small number of crossbow arrows that hit the bones only caused a bone to shatter at most.

But there are hundreds of bones on a skeleton!

In desperation, Night Blade could only swoop in the direction of those giant rats from the air, preparing to engage in hand-to-hand combat with these monsters.

Because the dragon's long-range attack method is only Dragon Flame Breath, but with this ability alone, it is impossible to quickly annihilate so many G virus mutants.

And in this time, the casualties of the summoned beasts under his command don't know how heavy they will be.

At the same time, just as Nightfront was about to fly above the giant rats, he saw that the giant rats also immediately shot hairy crossbow arrows in the direction where he was.

Before, they had no way because of the range and angle, but now that he was diving down, he was impressively within their firing range.

"Jingle Bell!"

With the sound of gold and iron, I saw that these hairy crossbow arrows shot on the dragon's dragon scales, and they also splashed in an instant, but in the end, the dragon scales' defense was superior, and the sharp haired crossbow arrows did not penetrate the hard dragon scales, but only left a white mark on the surface of the dragon scales.

It's just that although the damage caused to him by this hairy crossbow arrow is not high, the pain caused by it is a lot of welling up in his heart.

Under the extreme pain, the vertical pupils of the dragon, who had turned into a giant dragon at this time, also suddenly flashed a trace of ruthlessness and resoluteness, and then saw that his entire body had no intention of slowing down, as if Mars hit the earth, and fell towards the ground without hesitation.

"Bang" with a loud bang!

I saw that the ground seemed to have a strong earthquake, and countless sand and gravel debris rose into the sky, like a sandstorm on the flat ground.

At the same time, I saw that on the originally flat ground, a huge earth pit suddenly appeared, and I saw that this soil pit was about 100 meters in size, and its deepest point reached an astonishing depth of ten meters.

Even if he was as strong as a dragon, he had suffered a lot of damage in the face of such an impact, and in the feeling of Night Blade, it was as if his head had been hit hard, and he felt dizzy.

And even his own health was directly lost thousands of points in the face of this impact!

But it was all worth it, and when Yefeng shook his head and got up from the huge dirt pit, he saw that in the dirt pit, there were suddenly more than a dozen more bloody and fleshy meat sauces.

This is exactly the giant rat that didn't have time to escape, and was directly crushed into meat sauce by his weight plus the force of impact.

Then, he also immediately raised his dragon claws and rushed towards the remaining mutants, although the strength of these monsters was very strong, but under the attack of his ninth-order dragon, his defense was easily torn apart.

But unfortunately, in addition to the effective output he can inflict on these monsters, the attack effect of the rest of the summoned beasts is not very ideal.

Even the strong alien soldiers, a few together can barely deal with a giant mouse or a sandworm, as for the dozens of meters long mutant python, its strength is so strong, no more than five alien soldiers can not resist at all.

Even the high-level Ice Elemental Stasis Aquilis, whose ice spear was as powerful as an automatic rifle, couldn't shoot through the huge hard scales of the mutated python.

This kind of defense is several times stronger than the giant python mutated because of the blood orchid that Ye Feng encountered in the novice mission, you know, although his pistol bullet did not penetrate the giant python's scale armor at that time, it only left a shallow white mark on the surface.

However, it is important to know that he was not using a military pistol, but a police pistol.

Even if the pistols of the military and police have the same signal, their power is not the same at all, the army focuses on lethality, while the police focus on deterrence, and their main purpose is only to paralyze the enemy.

Therefore, the kinetic energy of the pistol used by the police is obviously not as good as that of the military pistol, and the pistol bought by Yefeng at that time was also a second-hand product, and the rifling and the like were also deliberately shallowed, which further reduced the lethality of the pistol.

It was precisely because of this that he was unable to shoot through the scale armor of the giant python with a pistol at that time, but I believe that if he had used an automatic rifle at that time, the effect must have been very different.

However, the ice spear cast by the Stasis Aquilis summoned by Nightfeng is definitely not inferior to the power of the automatic rifle, but now it can't break the scale armor defense of the giant python.

The strength of this mutant python's defense couldn't help but surprise him.

In the end, in order to solve the remaining dozen or so mutated creatures, with the addition of the ninth-order dragon of Ye Feng, the summoned beasts under his command actually lost a full dozen alien soldiers, 3 skeleton swordsmen, earth and rock golems and other melee elemental elves.

However, it is worth mentioning that in this fierce battle, there was actually a mutated creature that triggered the chance of enslavement and directly became a member of the summoned beasts under his command.

And this enslaved mutant creature is a giant mouse, and then he directly arranged it behind the defense line to use it as a long-range output, after all, its piercing power of hair shot is very good.

And in the following time, from time to time, a few or a dozen mutant monsters attacked, but fortunately, they were not only few in number, but also did not come together to attack.

Therefore, the pressure on them was not very great, except for the loss of a few melee summoned beasts such as alien soldiers, there were no other big losses.

However, all this changed later, and I saw that this time the mutant monsters that emerged from the depths of the underground space were densely packed with nearly two hundred heads!

In addition to the monsters that have already been seen, such as mutant pythons, giant rats, and mutant spiders, there are also monsters such as giant mutant giant wolves like elephants, giant centipedes more than ten meters long, and mutant giant scorpions the size of cars.

Looking at the mighty army of monsters rushing over, for a while, Ye Feng's heart actually had the feeling of monsters attacking the city in the game.

At the same time, he also subconsciously swallowed saliva because of nervousness in his heart, because the number of monsters this time was too much, a terrifying mutated monster of more than 200.

This kind of strength is difficult to stop with the summoned beasts under his command alone, even if he joins with the incarnation of a ninth-order dragon, because no matter how powerful the dragon's attack output is, how many monsters can be killed with ordinary attacks alone?

After all, the strength of these G virus mutants is very strong, even if he is a dragon, it is impossible to kill a mutant with a single blow with ordinary attacks.

Looks like it's time to use those killer features!

However, if you want to cast those killer features, you need plenty of time!

Thinking of this, Ye Feng's eyes also suddenly flashed a decisive look, and then, he immediately lay on the ground and chanted an unknown spell, accompanied by violent magic fluctuations, only to see that a series of materialized magic runes also appeared beside him.

At the same time, I saw that the remaining half of the alien soldiers, all the skeleton warriors, and the half-crippled stoneblade Lazer and other summoned beasts were directly sent to the front by him, and collided heavily with the army of mutants who rushed over.

Because if he didn't do this, if he didn't sacrifice these summoned beasts, then with the speed of those mutants, he would definitely rush into the defense line before he successfully cast the forbidden spell.

Therefore, in such a situation, Yefeng also has to break the wrist of the strong man and sacrifice a part of the summoned beast to win precious time for his forbidden spell casting!

Although the death of these dozens of alien soldiers and all the skeleton warriors only slowed down the mutant army for a few minutes, for him, these few minutes were enough!

With the disappearance of the last magic rune, the air on the field also fell into extreme tranquility in an instant, as if it was quiet before a storm.

At this time, the keen mutants also subconsciously stopped, only to see them looking around in a panic, because in their perception, it was as if there was a huge crisis about to swallow them.

Wild beasts are very sensitive to the premonition of danger, as if before every major earthquake, the beasts are always the first to notice, and some can even migrate more than ten hours in advance.

Then, after a few seconds in extreme silence, I saw that the feet of the mutant army suddenly began to slowly bulge, and finally gradually formed a hill dozens of meters high!

But what is terrifying is that on this hill, there is a red flame magma!

This is the Infernal Volcano, one of the three forbidden spells of the Fire Dragon!

At this time, those mutants were also frantically fleeing towards the surrounding areas of the volcano.

But unfortunately, it was too late for them to flee now, and then, I saw the volcano suddenly explode, and a fireball that spread nearly a hundred meters in a radius rose into the sky, and in this instant, the entire underground world seemed to have an extra sun out of thin air.

The dazzling light illuminated the entire underground world as if it were daylight, and under such a dazzling light, all living beings subconsciously closed their eyes.
