The dragon did not expect such an attack, so Alice's attack struck him in the head.
His vast and powerful body swayed backward as he was destabilized, and just then, Matt injected all his power into his fist and struck him in the stomach at the same time as Isla.
The impact sent the dragon's massive body back a bunch of steps until it stabilized and swung its tail to hit them.
Matt wouldn't use his sword this time, as it didn't do him much good. The stronger he got, the more he felt the sword was deficient. He couldn't show his full power due to the tool not being the right one.
That's why he stomped hard on the ground when he saw the dragon's tail coming towards him and threw a strong punch towards it, creating a powerful shock impact that sent him flying backward while the dragon was pushed to hit the cave walls.
'Holy shit, this bastard has over 5 thousand power.' Matt thought with difficulty as he got up from the rubble he had fallen into, launching himself back into the fray.
"Isla, come with me!" he shouted towards Isla as he appeared behind her.
One of the dragon's claws tried to strike her, while the dragon entertained Alice with fireballs continuously shooting out of its mouth.
Seeing this, Isla jumped on top of Matt, and they both disappeared. The huge dragon claw slammed into the ground, kicking up dust.
This confused the dragon, but before he could know what was happening, he felt a powerful presence heading towards him at full speed from above.
"Now, Alice!" shouted Matt as he increased his body weight to fall on top of the dragon with a mighty thud.
*BOOOOOOOOM!*
The impact sent the dragon forcefully downward, but before it could touch the ground, Alice's full power was revealed, and she appeared from underneath the dragon, attacking it forcefully with a horizontal upward swing from that position.
The dragon could not even defend itself from this sudden attack that had come upon it and was pushed forcefully upwards, which Matt and Isla took advantage of to give it a powerful attack, sending it slamming hard into the cave walls.
The impact of something so large caused the entire cave to shake, and light chunks of rock began to fall as if this place was breaking loose.
"How tough is this guy." Matt said as he fell to Alice's side next to Isla.
"Yeah, I thought I could have taken a big chunk out of his neck, but I barely and barely hurt him. What a tough guy." Alice replied as she frowned.
Although they thought so, they also realized that the dragon was undoubtedly injured.
While his power level wasn't as high as Alice's on a numbers level, being a dragon, he could have killed them if he was at his best.
Still, they didn't need to slit his throat to win because they knew that was nearly impossible.
They just needed to find that weak spot.
Alice looked at Matt, "Were you able to figure out his weak spot?" she asked, and Matt smiled.
"Almost got it." He replied, and just then, the dragon's roar made them alert.
This roar was so mighty that it echoed firmly in their ears and made them hurt; still, they held on as they were fighting stance, and just then, the dragon shot out of the dust that had risen, ready to attack them.
Matt activated all the power in his body and rushed at it first.
"Let me fight just for a moment; prepare to attack!" shouted Matt as he slammed into the dragon at high speed.
The dragon swung its claw to strike Matt and knock him out of the way, as its target was that woman who had hit him with the sword.
Still, Matt smiled as he watched it do this, and his fist filled with vampiric power, making it look slightly ghoulish.
The vampiric energy in his arm caused his muscles to grow, and Matt launched a punch in midair towards the dragon's head that had not yet reached him.
This left the three who saw it in shock.
'What the hell is this guy doing?' Was the thought the dragon had at that moment, thinking that he was already more than dead the person in front of him.
But without him noticing, a powerful energy in the form of a fist came out of Matt's punch, slamming hard into the dragon's massive head.
The attack was tremendous and from a distance, which confused him.
Even so, the impact stopped his attack and sent him several meters backward while his head bled.
The girls behind Matt were stunned to see this, "What the hell!?" they shouted in shock, but Matt didn't stop.
He activated his dimensional movement ability and appeared above the dragon, who was face up, falling to the ground with a confused mind, then attacked him hard in the stomach.
"BUAGH!" The tremendous impact caused a gush of blood to spurt out of the dragon's mouth, causing Matt to smile.
"The main wound is in its wings, and its weakest point is in the lowest part of its stomach!" shouted Matt.
Although the girls didn't understand how Matt had made that attack, they immediately jumped when they heard this, aiming at the spot Matt had said.
Meanwhile, Matt jumped back, spreading his arms wide.
His spiritual energy shot out in various directions like little invisible strips, and they clung tightly to the stakes he had placed earlier.
Then, Matt pulled them with force and precision toward the dragon that was still a little dazed by the attack.
Just at those moments, an attack from Isla landed on one of the dragon's wings, while a powerful attack from Alice landed on the stomach, exactly where Matt had told her.
"BUAAGHHHHHHHH!" A cry of pain erupted from the dragon's mouth at that moment, but soon, a large number of iron-reinforced stakes strengthened by Matt's vampiric power fell on its weak spot again and again.
The one who fell first was pushed by the next one, and then the next one pushed them both. It was a succession of coordinated attacks, one after the other, which caused the stakes to pierce the dragon's scales soon, and a great spurt of blood came out of his stomach.
When Matt saw this, he jumped into the air again, "At once!" he shouted, and three powerful attacks shot out shortly after from their respective places, impacting hard on the hole in the dragon's stomach.
These powers went into his body and destroyed a portion of the dragon's organs, bringing him to his death.
