The Brain Demon was originally a creature with an outstanding talent in mental attack, so Li Yin and Yu Canglong's private communication was discovered by the Brain Demon at the first time.

The Brain Demon's attack was extremely strong, and the tentacles slammed out, slamming into the bodies of the three-headed Wyvern and the heavily armed Earth Walking Dragon.

Completely different from before, the brain demon only has two tentacles, but at this moment, it has eight more tentacles, a pair of black meat wings, and a tail.

The Brain Demon, whose image had changed drastically, severely injured the three-headed Wyvern and the Heavy Earth Walking Dragon with a single blow.

The vertebrae of the head in the middle of the three-headed wyvern were immediately snapped, and with a scream, he flicked his wings and barely flew out.

The three-headed wyvern escaped, but the reloaded Earth Dragons didn't have such good luck, and the tentacles of the brain demon slammed into its body, and the all-metal armor was directly dented.

The tentacles of the Brain Demon rolled the Earth Walking Dragon, and a slender mouthpiece stretched out from the pile of soft flesh of the Brain Demon and stabbed into the Earth Walking Dragon's head, and the Earth Walking Dragon trembled, his expression full of horror.

In the blink of an eye, the marrow of the Earth Walking Dragon was sucked dry, and the brain demon smashed it towards Yu Canglong and Li Yin like garbage.

Although the Velociraptor of the Royal Canglong was killed by Li Yin, where was the strength of the Royal Canglong itself, activated a C-level wind system auxiliary card, and dragged Li Yin out.

"Stupid human! I wanted to open the door of the laboratory with your hand, but I didn't expect you, a brainless human, to be easily deceived! Humans are really unreliable creatures!"

The brain demon directly presented its thoughts in the minds of everyone with the voice of spiritual power, giving people an extremely evil and cold feeling. During this period, the spiritual power of the brain demon was also swept over Li Yin's body, and Li Yin could feel the powerful and evil spiritual fluctuations of the brain demon, if he really had an energy card on his body, he might have been discovered by the brain demon and launched an attack on him. It's just that the spiritual power of the brain demon was only swept away on his body, and as the brain demon's thinking fluctuations were broken, a pair of huge meat wings spread, dragging a huge body into the sky, and eight thick tentacles were fiercely pumped towards the laboratory, and the zenith of the laboratory was immediately pulled out of a big hole.

"Who do you think I didn't find out that you saved your strength?

When Yu Canglong saw that the brain demon had undergone such a big change, his face suddenly changed, obviously he didn't expect such a big change in the brain demon, but Yu Canglong didn't want to lose face, and the dead duck said stiffly.

And he also conveniently blocked Li Yin behind him, and the four more exquisite, gold-painted war beast cards were shot out by the dragon like a dart.

The four war beast cards scattered around the sky above the brain demon like living creatures, and the four cards lit up in an instant.

"Roar!"

A deafening roar rang out, and four drake beasts, also wearing metal armor, were released.

Li Yin secretly glanced at Yu Canglong, and after seeing that he didn't seem to be abnormal, he secretly breathed a sigh of relief.

The Brain Demon obviously saw that the energy card he handed over to Yu Canglong was a waste card that had run out of energy, so he said what he said before, but Yu Canglong misunderstood, thinking that the Brain Demon was talking about bringing it here, which made Li Yin not exposed.

At the moment when the four-headed war dragon beast appeared, the card analysis function of the "Card Dian" also fed back the information of the four war beast cards of the Royal Canglong, which immediately made Li Yin gasp.

A two-meter-tall, crimson humanoid dragon beast with a set of metal armor and claws that ignited raging flames, slamming the base of the brain demon's flesh wings with the momentum of falling from the sky.

"C-level war beast card, Red Flame Tyrannosaurus, primary armament, comprehensive strength C+. ”

A wingspan of three meters, like a birdman before, a pterodactyl with a bluish purple electric light, with a rapid speed, attacked the base of the other fleshy wing of the brain demon.

"C-level war beast card, winged hand electric dragon, primary armament, comprehensive strength B-. ”

Both the Red Flame Tyrannosaurus and the Pterodactyl were equipped with sophisticated metal weapons or armor, and their goals were clear, attacking the Brain Demon's flesh wings and cutting off its superiority in the sky.

But the brain demon is not a dead thing, when the two dragon beasts attacked, they immediately waved their tentacles and pumped towards the two dragon beasts.

Suddenly, countless streams of water appeared, and they became entangled with the tentacles of the Brain Demon, firmly imprisoning the tentacles of the Brain Demon, making it unable to attack the Red Flame Tyrannosaurus and the Wing Hand Light.

A battle dragon beast that was only more than a meter long, and from a distance, it looked like a blue water snake, appeared in time, and used the water flow to delay the attack of the brain demon.

"C-level war beast card, water soul dragon, primary armament, comprehensive strength B-. ”

Dragged by the flow of water, the brain demon suddenly lost its best chance to defend, and was hit by the Red Flame Tyrannosaurus and the Pterodactyl at the same time, and let out a roar, falling from the sky and slamming into the courtyard of the laboratory.

The cooperation of the three-headed dragon beast made the brain demon suffer a big loss almost instantly, based on this alone, Li Yin had already seen that the true strength of the dragon was definitely not something he could match, and the reason why he was able to win narrowly was that the dragon didn't care.

The brain demon who was hit hard by just one shot felt that he was very faceless, and let out a roar, and the eight tentacles broke free from the shackles of the water, and fiercely pulled towards the three-headed dragon beast that was still on his body and ready to attack.

"Whew!"

As soon as the Brain Demon attacked, a terrifying roar rang out from the mouth of the fourth dragon beast.

This dragon beast is completely different from the previous dragon beast, with a pure dragon body, a pair of broken meat wings, dragging half a tail, it looks extremely vicious, but its body is only ten meters long, it is pitch black, and its body is covered with hideous wounds, as if it has experienced some cruel blow.

"B-level war beast card, dark demon dragon, high-level armament, comprehensive strength A+. ”

As soon as this dark demon dragon appeared, it showed its relatively intact claws, and with a black mist, it grabbed the soft flesh of the brain demon, and the huge mouth full of cold light was also wide open, and it bit down fiercely.

The brain demon suddenly shook when the Dark Demon Dragon appeared, as if it had seen something terrifying, but when it saw the appearance of the Dark Demon Dragon in front of it, its eyes were shining.

Directly gave up the other three-headed dragon beasts bouncing on him, and attacked all the tentacles towards the Dark Demon Dragon.

Just when Li Yin was puzzled about how this dark demon dragon could have such a high comprehensive strength when it looked like it would hang at any time, the voice of the soul suddenly sounded.

"Beep beep! Identity verification! The 913th team of the Demon Dragon Patrol, ten people are dark souls, and the current strength is 29% of the heyday."

Li Yin raised his eyebrows, he was a survivor of that era of souls!

Squinting his eyes and glancing at the Dark Demon Dragon, Li Yin began to guess that the reason why the Imperial Dragon was able to control so many dragon beasts with dragon bloodline might have an inseparable relationship with the Dark Demon Dragon.

"Oh, isn't this a patrol bug! There are still some who haven't died! These worms are so tenacious!"

Just when the Dark Demon Dragon and the Brain Demon were completely twisted together, the elusive Golden Toad suddenly appeared on Li Yin's shoulder, staring at the Dark Demon Dragon with surprise in his tone

Li Yin was shocked, Jin Toad's voice was so loud, for fear that Yu Canglong wouldn't hear it!

But fortunately, as if he hadn't heard it, Yu Canglong stared at the battle group intently, without the slightest intention of turning back.

"Don't worry, I don't want others to hear the voice, others will never hear it. ”

Jin Toad could see what Li Yin was thinking at a glance, and the toad grinned, and immediately said proudly.

"This thing has a big mouth, and in the first place, Cadian added such an extra function to it in order to prevent it from leaking confidential information."

As soon as Jin Toad's voice fell, the voice of the soul also rang out, telling the truth of the matter without giving Jin Toad any face.

Li Yin was dumbfounded, feelings are such a thing, but think about it, with Jin Toad's long-winded personality, it is very likely to leak information, and Kadian is careful to think about it.

The pierced Jin Toad was suddenly like a deflated ball, lying on Li Yin's shoulder softly, and honestly closed his mouth.

In the brief exchange between Jin Toad and Li Yin, the occupation of the Brain Demon and the Dark Demon Dragon has changed, after all, the Dark Demon Dragon's strength has seriously decreased, and the wound has not healed, after the Brain Demon's tentacles frequently draw the wounds on the Dark Demon Dragon's body, the Dark Demon Dragon's attack strength is even weaker.

Gradually, the brain demon took over the upper hand, and the most terrifying thing was that the brain demon's slender mouth that sucked people's brain marrow always stabbed out from time to time, wanting to pierce the head of the dark demon dragon and suck its brain marrow.

The Dark Demon Dragon obviously knows the habits of the Brain Demon very well, and is always on the lookout for the Brain Demon's surprise attack, and every time it flashes dangerously.

Even so, the Dark Demon Dragon's physical condition was getting worse and worse, and eight retractable tentacles were wrapped around its body, preventing it from having a chance to escape.

The other three-headed dragon beasts did not relax in the slightest, and were always attacking the body of the brain demon, but no matter what kind of damage was caused, the soft flesh of the brain demon would immediately return to its original state after a burst of wriggling, and its self-healing ability was amazing.

"This mind demon has already used part of the forbidden spell on its own body, its tentacles are tentacle demons, its wings are those of the flesh feather clan, and even the scales on the surface of the body are those of the dragon clan, which is a bit too fast to heal itself, it must be because it integrates the core cells of the worm clan into its body. ”

"Now this brain demon has not used the most terrifying spirit attack to fight so durably, once it moves its true character, the dark soul alone will definitely not be its opponent. ”

After carefully examining the body of the brain demon, the soul reported the characteristics of its body one by one, Li Yin immediately felt very tricky, everything else is easy to say, but the self-healing ability, Li Yin has no way, even if his Vulcan cannon attacks with all his might, he can't kill the entire body of the brain demon in an instant.

"Soul Move!"

Seeing that the battle situation was getting more and more unfavorable, Yu Canglong was also anxious, gritted his teeth and directly took out a piece of pitch-black scales, bit his fingers, dripped blood on the scales, held it in his mouth, and shouted.

In the next moment, countless black textures spread out from the corners of the dragon's mouth on both sides to the whole body.
