After careful consideration, Yusei ultimately gave up.
He currently had the [Dragon Slayer] ability, which had been enhanced to have a certain probability of being lethal.
Yusei naturally didn't dare to use this. What if he actually won the lethal lottery and killed Tohru's father?
Right now, even though the father and daughter were fighting fiercely, neither was going for a killing blow. Yusei also had no deep-seated hatred for the other party, so naturally, he couldn't go for a kill either.
'So in the end, only Sunshine Girl help me?' Yusei sighed and quietly said to Tohru, "Tohru, prepare for close combat. My Susanoo will assist you."
"Okay."
Yusei manipulated Sunshine Girl ability to create a dense fog over the area, which spread rapidly. The density of the fog was also abnormal.
Seeing this, Tohru's father became interested.
"Trying to use the fog as cover to attack me? A decent plan. But..." Tohru's father flew upward, the wind from his wings directly blowing away the fog in front of him.
Yusei felt no regret. He knew such a technique couldn't stop the opponent.
However, his attacks weren't limited to this.
Sunshine Girl could utilize meteorological forces. All those weather disasters were within Yusei's ability range.
The purpose of raising the fog earlier wasn't just to block vision, but also to fill the air with moisture.
Yusei manipulated the weather. Torrential rain poured down, drenching Tohru's father.
"Heavy rain? A very natural force. It almost seems like nature itself is helping you. But, so what?"
Tohru's father wasn't in a hurry to attack, but looked at Yusei with interest.
"Of course it's not over." Yusei sneered, and with a thought, the power of frost spread.
In this bizarre climate, dense fog, heavy rain, and frost all converged to assault Tohru's father simultaneously.
As Yusei urged his power, the frost spread faster than imagined, actually forming ice directly on Tohru's father's body, and very rapidly at that.
Seeing this, Tohru's eyes lit up. She knew this was the 'opportunity' Yusei had just mentioned to her.
Use fog and rain to fill the air with moisture, then use frost to freeze, and finally deliver the final blow in close combat.
While Yusei was activating the frost, the Susanoo didn't stop either. It directly drew a long sword.
Tohru, as if standing up, gripped that energy long sword. With the Susanoo's assistance, she tightly held the sword and swung it with all her might at her father.
Boom!
With Tohru's father as the epicenter, the ground directly caved in, forming a large crater. Under the force of this sword strike, he seemed to be driven straight into the earth.
Energy scattered, and countless fissures spread out in all directions into the distance.
The ground beneath their feet shattered, and countless fissures spread. Under the power of this Susanoo-cladded Dragon.
The mountain several kilometers behind Tohru's father was also split in half.
Along the way, the bottomless fissure proved the power of this sword strike, while also demonstrating how powerful Tohru's father was to withstand it.
The Dragon Clan's training grounds were also largely shattered by the Susanoo-cladded Dragon's single strike, with rubble and fissures everywhere.
The noise here attracted the attention of the dragon soldiers on duty, who flew towards them.
Even though this was a training ground meant for combat, they had never seen such a huge commotion.
Tohru's father, having withstood this strike, was breathing slightly heavily. Seeing the soldiers approach, his voice spread throughout the area.
"Do not approach."
Hearing this, the soldiers stopped.
Tohru's father is the Dragon King, and they could recognize the Dragon King's command.
Without the slightest hesitation, they immediately turned around and returned to their duties.
Tohru's father's hand was covered in black energy, his dragon claw blocking the blue energy long sword.
He said in admiration, "A most impressive attack. Even I had to expend some effort to block it."
"Expend some effort?" Yusei's eye twitched slightly. He asked Tohru uncertainly, "Tohru, is your dad bluffing or not?"
"What he said is true. Father himself possesses the power to destroy worlds. However, as guardians of order, the Dragon Clan cannot do such things," Tohru said seriously.
Yusei said helplessly, "But when you first arrived, you said you wanted to destroy the world and eliminate humanity."
Tohru looked somewhat embarrassed, laughing it off, "That's different. Father's power is transcendent and bound by rules. I'm not really bound."
"Transcendent power? Then we won't hold back. Let's go all out."
"Huh? All out? Yusei, you haven't been using your full strength?"
Yusei smiled and said, "Of course not. But we need to separate temporarily. When I enter that state, my body will be filled with sword energy, which could cut you."
"Okay, then let's fight two against one."
The two quickly communicated.
Yusei separated from Tohru, returning to his normal state.
Seeing this, Tohru's father said indifferently, "Have you decided to admit defeat?"
"Of course not. Faced with your strength, I intend to use my full power."
"Full power? Heh, not bad, human." Tohru's father rarely offered praise.
Yusei paid no mind... His body was instantly covered in blue Sword Intent energy.
[Sword Intent Mode]
But that wasn't the end. The next moment, the essence of lightning energy between the sky and ground erupted, and Yusei directly channeled it into his own body.
Simultaneously, the blue Susanoo rose. This time, compared to before, it was not only more solid, but also took the form of a blue energy humanoid figure.
If the Complete Body Susanoo resembled a masked Tengu Warrior, then this seemingly Ultimate State Susanoo was like a warrior wearing full armor.
Yusei had noticed before that because this world's energy was vast and dense, the power he could control when manipulating weather forces was also purer.
Simply put, the power was stronger.
This was the first time Yusei used such strong energy as a 'battery' to charge the Susanoo.
Compared to this Susanoo, the previous [Ultimate Susanoo] was almost like a joke, as it was limited by the world's energy level and didn't receive much of a boost.
The current Susanoo was different. This world's energy was immense. The channeled lightning power was almost too much for the Susanoo to contain.
Activating Sword Intent Mode wasn't for amplification, but for stability. While greatly enhancing his physical qualities, Yusei's control over every part of his body also increased, allowing him to better control the massive Susanoo.
