Chapter 458
Thinking of this, Xiao Yu no longer hesitated.
The 100-meter-long black dragon began to rush towards the black mountain of meat ahead.
The Underground King had no defense, and at this moment Xiao Yu directly released his ultimate move.
——World-Destroying Burning Flame!
I saw the 100-meter-long black dragon opening its mouth, and a reddish light surged from the dragon's head.
After a short period of energy accumulation, a burst of crimson flames burst out in the next second, which felt like an explosion.
The ultra-high-temperature flames, carrying terrifying energy that seemed to be capable of destroying the world, blasted directly toward the black mountain of flesh in front of them.
"Boom-boom-!!"
"Boom!"
…
The energy ray formed by the terrifying flames directly penetrated the underground king's huge body, leaving a hideous and huge wound on it.
Xiao Yu maintained the spraying state for several seconds, and finally closed his mouth to end the attack.
As the crimson flame energy dissipated in the sky, a large number of energy spilled particles fell to the ground.
The energy particles spilled from these world-destroying burning flames formed huge char pits instantly when they fell on the ground.
It was enough to prove the terrifying power of Xiao Yu's attack.
"Ho-ho!"
The Underground King also let out a somewhat slow wail of pain.
Looking carefully, the black matter on its body has begun to heal.
Xiao Yu noticed.
Compared with the speed at which the Underground King healed itself before, this time the opponent was obviously slower.
If the huge hole blasted out by the World-Destroying Burning Flame relies on this kind of self-healing speed, it will not be completely healed even if it takes a day.
Of course Xiao Yu also understands.
With just that blow, it was still not possible to completely kill the Underground King.
This can only cause moderate damage to the opponent at best.
In addition, the underground king's self-healing ability is affected, and it can be considered a serious injury.
Chapter 420: Heavy damage to the Underground King
Xiao Yu looked at the Underground King in front of him.
Su Bai's control time is limited, and he must cause as much damage to the Underground King as possible before the effect of the Aurora White Dragon Domain ends.
It's best to beat it to near death or even kill it directly!
Boom boom!
The brilliant crimson flame light column appeared again.
Xiao Yu launched the World-Destroying Burning Flame for the second time.
The terrifying energy light directly penetrated the wound of the Underground King that had not healed before.
"Buzz!"
The Underground King was under the control of the Aurora White Dragon Domain.
This blow was still undefendable.
A shrill, shrill sound came from its body, as if it was wailing in pain.
"Ho ho, ho ho..."
…
In the sky.
At this time, Su Bai was watching the battle below.
Seeing the terrifying flames in Xiao Yu's mouth, Su Bai couldn't help but feel a hint of horror in his heart.
"Is this the true strength of the "World-Destroying Black Dragon"? "
Xiao Yu, as the boss of the Black Dragon Group, was dubbed the "World-Destroying Black Dragon" by the genetic modification company.
Its strength is definitely in the top three among the genetic modification experimental projects carried out by genetic modification companies for decades!
Although Su Bai has now broken through to the king level.
But looking at the world-destroying burning flames below, he didn't have any confidence that he could proceed.
Only the Underground King opposite Xiao Yu, with his king-level powerful body, could withstand such a terrifying attack.
However, after taking two big-level attacks from Xiao Yu in succession, even the underground king of the same level was in a very bad state at the moment.
…
on the ground.
The Underground King, who looked like a small mountain, had two terrifying holes blasted out of his huge body by Xiao Yu's flames.
The disgusting-looking black substance on it was constantly squirming, but within Su Bai's Aurora White Dragon domain, the effect of the Underground King's body's self-healing ability was greatly slowed down.
Facing the two horrific wounds on his body, the self-healing speed of the black substance seemed meaningless.
…
"Ho ho, ho ho..."
The underground king's slow speed suddenly changed, and the huge black mountain of flesh began to move quickly.
At the same time, Su Bai's expression changed slightly in the sky, and he quickly transmitted a message to Xiao Yu below.
"Brother Xiao Yu, my domain ability can't support it. The monster is out of control!"
Then Su Bai directly removed the Aurora White Dragon Domain from this space.
Suddenly, all the pale energy in the surrounding space quickly moved toward the aurora white dragon wings behind Su Bai.
The surroundings are back to normal again.
…
"Yes, I understand, Brother Su Bai!"
On the ground, Xiao Yu's dark red dragon pupils were filled with concentration.
He stared at the Underground King in front of him seriously.
Su Bai's field effect allowed him to fire two shots of 100% world-destroying burning flames against the Underground King.
With this level of skill, even if the Underground King is also at the King level, he still can't handle it.
At this time, although the confinement effect of the Aurora White Dragon Domain was lifted.
But the injuries on the Underground King's body could not be healed in a short time.
Xiao Yu's World-Destroying Burning Flame doesn't just have damage power.
Among them, the World-Destroying Burning Flame comes with terrifying burning, continuous damage and death effects.
If it had been before, he might have given up hunting the Underground King with a high probability.
But the Underground King took two shots of the World-Destroying Burning Flame.
Xiao Yu's confidence in defeating the opponent has now greatly increased.
He did not hesitate. Now that the Underground King's body had been severely damaged, it was a good time for him to pursue victory.
Xiao Yu ran quickly, and the 100-meter-long black dragon sprinted forward.
…
In the sky, Su Bai had already put away his attack state.
He waved his white dragon wings and flew high in the sky, preparing to watch the battle between Xiao Yu and the Underground King.
In fact, when Su Bai used the Aurora White Dragon Domain just now, he did not reach the limit.
If he uses the Aurora White Dragon Domain with all his strength, Su Bai estimates that there is a high probability that Xiao Yu can use the World-Destroying Burning Flame three times.
But Su Bai didn't intend to do this.
After two rounds of World-Destroying Burning Flames, the Underground King was almost half disabled, and Xiao Yu could basically deal with it.
Secondly, Su Bai didn't want to expose all his strength in front of Xiao Yu, especially in a powerful space domain like the Aurora White Dragon Domain.
Su Bai looked down, looking at the 100-meter-long black dragon and the 300-400-meter black mountain of meat.
At this time, the two started the most primitive hand-to-hand melee combat.
Xiao Yu had previously released two rounds of world-destroying burning flames, and the energy consumption in his body was also very serious.
However, compared to the Underground King, Xiao Yu's advantage is undoubtedly greater.
…
The battle between the two was originally evenly matched before, but after Su Bai's intervention, the battle situation has now become one-sided.
"Boom! Boom!..."
Xiao Yu's modified gene is worthy of being a black dragon.
The sharp and ferocious black dragon claws struck the Underground King one blow after another.
The Underground King, who was already in serious trouble, felt like he was being hit hard at this time.
Ten minutes later.
The Underground King was retreating steadily, and the two huge wounds on the black flesh mountain were now replaced by dozens of large and small ones.
Even though it was huge, its body couldn't withstand Xiao Yu's bombardment.
…
