Only the upper body of the Nine Nether Demonic Jiao was exposed, and part of the scales on its skin could be clearly seen, with dark red traces burned by incendiary bombs.
Water monsters are most afraid of flames and all kinds of hot things.
When the incendiary bomb sank to the bottom of the river just now, the Nine Nether Demonic Dragon swam over curiously because he didn't know what it was.
Unexpectedly, under unexpected circumstances, the incendiary bomb suddenly exploded into a billowing wave of fire.
Although he only suffered a little superficial burn, the sudden shock from the incendiary bomb undoubtedly completely angered the Nine Nether Demonic Jiao.
After all, it has some dragon bloodline inheritance in its body.
That kind of unruliness and dignity cannot be provoked!
"Chichi!"
The Nine Nether Demonic Dragon's huge mouth roared ferociously, and as it roared fiercely, it spewed out streams of black mist.
The black mist is filled with extremely strong toxicity, and as soon as the soil touches it, it instantly turns into a black sticky substance.
As for any human martial artist who is contaminated, if the protective energy shield cannot support it, his flesh and blood body will instantly turn into a pool of blood and mud, and even his bones will be corroded.
Suddenly, under the erosion of the black poisonous mist, there were screams one after another!
However, everyone did not sit still and wait for death. After a brief period of shock, they quickly launched a counterattack.
During the surge of Yuanli, fierce martial arts offensives were launched one after another, blooming with brilliant light.
"Bang bang bang...!!"
As the battle started, fierce bombardments suddenly sounded one after another.
At this time, Ye Yang, who was the instigator, did not escape, and together with many martial arts cultivators, they attacked the Nine Nether Demonic Jiao with all their strength.
What he wanted was this kind of result. Instead of using it as a bait to let the people of Wu Meng Sect benefit, it would be better for everyone to suffer together.
In this way, the power of resistance can be greatly enhanced.
Due to the large number of human martial arts members and the suppression of many half-step Holy Spirit Realm experts, the Nine Nether Demonic Dragon's attacks were fierce and it was difficult to gain the upper hand for a while.
However, the scales on the body of the Nine Nether Demonic Dragon Beast are extremely hard, so it is difficult to cause serious damage to it with such an intensive attack.
Only those martial spirits with fire attributes can have some effect.
"This beast is afraid of fire, so use fire attacks!"
Youdan's eyes flashed, and upon realizing this, he immediately adjusted his offensive strategy.
As soon as he finished speaking, he took out a red jade slip.
This is the formation jade slip that the master gave to the sect before he left. It contains fire-based formations, which has a restraining effect on the Nine Nether Demonic Jiao.
It was originally intended to be used at the end of the secret realm experience and on the return trip in case of emergency.
But because of Ye Yang's interference, this beast came up, so now it can only be put to use in advance.
Buzz!
Following the activation, the jade slip trembled slightly, the runes on it radiated light, and powerful energy fluctuations suddenly filled the air.
Immediately afterwards, rays of fiery red light shot out and quickly connected with each other, quickly forming an extremely huge mysterious formation.
The formation vibrated, faintly exuding a scorching fire energy, which directly enveloped the Nine Nether Demonic Dragon.
Taking advantage of this opportunity of suppression, they had enough time to rush into the undercurrent vortex at the end of the underground river and successfully enter the core area of the secret realm.
But at this time, Youdan did not choose to take advantage of the opportunity.
Because there is only one fire-type jade slip, if we don't take advantage of the situation to completely maim this Nine Nether Demonic Dragon, then we will definitely suffer its revenge on the way back, resulting in even greater casualties.
So now, this guy must be killed in advance or severely injured!
"Everyone, this beast has a cruel temperament. Although it is suppressed by the formation for the time being, it will definitely pass through this place again after the exploration of the secret realm is over in a few days!"
Seeing that many martial arts cultivators were ready to take action, Youdan looked solemn and shouted coldly: "By then, even if you get the treasure, you will probably fall into the mouth of this monster!"
"So, if you want to solve the future troubles, please follow me and pour your own energy into the formation and kill it together!"
"Otherwise, no one can get any benefits!"
Hearing these words, the surrounding warriors hesitated slightly and looked at the undercurrent vortex not far away.
"Roar!"
Just when everyone was hesitating, the Nine Nether Demonic Dragon roared, opened its ferocious mouth, thrust out its sharp claws, and struck heavily on the light screen of the formation.
The terrifying impact of power caused the formation's light curtain to ripple violently, directly diluting it.
Seeing this, the expressions of many warriors changed drastically. Without any hesitation, they all stretched out their hands, bursting out beams of vitality light and pouring them into the formation.
Regardless of the outcome, this Nine Nether Demonic Dragon is indeed a major obstacle to the return journey, even if they are lucky enough to enter the core area of the secret realm.
However, when we return, we will have to come back to this underground river again, and I'm afraid it won't be so easy to escape.
Taking advantage of the situation to solve it at this moment is undoubtedly the best strategy!
In this regard, Ye Yang naturally did not do anything thief, but also contributed his own strength.
"Buzz! Buzz! Buzz...!!"
With the infusion of countless Daoyuan force light beams, the fire array that was about to be broken suddenly became solid again, filled with more intense flame energy.
Moreover, the sturdiness of the formation light curtain is several times stronger than before!
The attack power of the Nine Nether Demonic Dragon is indeed very powerful. When fighting alone, even a true Holy Spirit Realm powerhouse may not be able to do anything to it.
However, with the full strength of so many martial arts practitioners and the suppression of the formation, he was suppressed and unable to escape at this moment.
"The Burning Sky Formation, the Fiery Sword Power!"
With the cooperation of everyone, Youdan's confidence skyrocketed, he controlled the fire array, and began to launch array attacks.
Under the condensation of the energy of the formation, a red giant sword was quickly formed, its whole body filled with blazing flames.
Then the fire sword suddenly slashed down, slashing hard at the huge beast body of the Nine Nether Demonic Dragon.
"boom!"
Facing such a powerful fire attack, the Nine Nether Demonic Dragon's scale armor defense could not withstand it no matter how strong it was.
As the firelight splashed, he opened his mouth and let out a shrill roar. The scales on the beast's body were instantly covered in flames and then exploded.
Dark red blood gurgled along the wound, splashing white smoke on the river.
However, such severe damage still did not completely kill the Nine Nether Demonic Dragon. Instead, it aroused this guy's rage.
In severe pain, it seemed to have fallen into madness, roaring and roaring continuously, and streams of thick black mist spewed out, quickly filling the entire formation area.
Under the cover of the black mist, its figure was actually submerged.
Just when everyone was shocked, they heard a "bang" sound, and a hole was opened underneath the formation's light curtain.
The Nine Nether Demonic Dragon also quickly emerged from the hole and fled deep into the river bottom.
Seeing this, You Dan, Teng Chi and many other sect masters were secretly speechless.
Unexpectedly, even with the joint efforts of so many martial arts practitioners present, they still could not defeat this monster, and even allowed it to break through the formation and escape!
