"What does the Fist King mean by this? Why attack my King?"
Erica, holding her sword, stood guard in front of Yusei, watching Luo Hao warily.
A faint smile played on Luo Hao's face. She didn't speak, just looked calmly at Yusei.
"Do you know what is most important in our country?"
"'Of all virtues, filial piety is the foremost,' right?" Yusei shrugged. He already had a rough idea what Luo Hao was going to say.
Sure enough, her next move was to throw a punch, but Yusei easily dodged it.
"Calling me a hundred-year-old elderly woman? You have quite the nerve. Since you know that saying, how come you don't know to respect your elders? Let me properly teach you how to respect your seniors."
"I don't think what I said was wrong. So how do you plan to teach me? Fighting here would alert the enemy, wouldn't it?" Yusei pointed at the ground beneath them.
"How about we don't use Authorities?"
"Whatever. Anyway, you can't win against me regardless. Let's use this contest to decide who takes the initiative in our cooperation." A confident smile spread across Yusei's face.
Hearing this, Erica was delighted. If there was no fight with the Sword King, then a fight with the Fist King would have an even better effect.
After all, the Fist King was an ancient Campione on the same level as Marquis Voban. Fighting her would make her King even more famous.
But at the same time, she was somewhat worried. Yusei's opponent was the Fist King, Luo Hao.
Luo Hao was an ancient martial artist, her martial skills peerless in the world. Even the Sword King, who was proficient in swordsmanship, could only match her in swordplay and couldn't even defeat her.
It was easy to imagine how badly Yusei would lose if he didn't use Authorities.
From Erica's perspective, Luo Hao was indeed somewhat 'underhanded', using her own advantage to attack Yusei's weakness.
But she didn't know that choosing to fight Yusei without using Authorities was the most foolish choice Luo Hao could make.
Erica respectfully led Luo Hao and Yusei to the underground training ground.
The Copper-Black Cross, to prevent attacks from rival organizations, had built a base underground for retreat purposes and for the magicians stationed here to train.
A battle between Kings could be observed, but Yusei specifically requested no spectators, so everyone complied.
The battle between the two lasted over thirty minutes.
Roughly thirty minutes later, the two emerged from the basement.
Unlike her initial calm demeanor, Luo Hao now looked fatigued. Even her Hanfu had several cuts from sword strikes.
However, Yusei had draped his coat over her, so the cuts on her clothes underneath weren't exposed.
Yusei was in much better shape, just slightly disheveled.
What surprised everyone was that in the battle without using Authorities, it seemed Luo Hao had come off worse.
This not only left her disciple, Lu Yinghua, dumbfounded but also shocked Erica immensely.
She was well aware of Luo Hao's strength, reputed as the world's number one martial artist. How could she lose in martial arts? Although Luo Hao currently didn't have as much dust on her as Yusei, her breathing and complexion clearly indicated she had been at a disadvantage.
However, this was a battle between Kings, and they didn't have the right to ask for details.
Yusei didn't deliberately boast about it either. Luo Hao naturally had nothing to say.
After being led upstairs by Erica to change clothes, she finally remembered to shoot Yusei a fierce glare.
"Although I'm happy to see my little brother can hold his own, as your elder sister, I'm still somewhat unhappy."
Hearing this, Yusei spread his hands helplessly, "I surrender. Let me off the hook. You'll have plenty of chances to fight in the next couple of days. Why must you fixate on me?"
The people around them were stunned by their addressing each other as sister and brother. Erica even subconsciously thought of a clichéd plot about long-lost siblings but quickly ruled out that possibility due to the age difference.
Neither Yusei nor Luo Hao intended to explain to them, so as subordinates and disciples, they couldn't very well ask.
But both Erica and Lu Yinghua could roughly tell that the relationship between Yusei and Luo Hao seemed to have improved quite a bit.
Speaking of which, one must mention Luo Hao's admiration for Yusei's martial skill.
Luo Hao wasn't sure about Yusei's other martial arts, but in terms of swordsmanship, she was completely led by the nose.
Yusei had the superhuman perception and dynamic vision of the Sharingan, combined with his mastery of the Hiten Mitsurugi-ryu. The Sharingan's enhancement to close combat alone made it impossible for Luo Hao's attacks to land on him.
Therefore, Yusei's martial skill earned Luo Hao's recognition.
Luo Hao thought highly of Yusei, so during the battle, she proposed the idea of becoming his elder sister.
Yusei didn't mind and casually agreed during the fight.
Subsequently, the elder sister, Luo Hao, was instantly defeated by Yusei's Kuzuryusen using the back of his blade.
Fortunately, a Campione's body was extremely tough, so there wasn't much actual damage, mostly just a few cuts on her clothes.
But since it was done with the back of the blade, Luo Hao considered it a disgrace. However, the other party was now her little brother, which made her very displeased.
She felt she was inferior to her little brother, which is why she was unhappy even after emerging, despite having gained a brother.
After agreeing on a time with Luo Hao, Luo Hao left for her temporary residence in Japan.
When Yusei was ready to act, he could directly contact Lu Yinghua.
After Luo Hao left, the residence seemed to quiet down significantly.
Yusei had also expended quite a bit in the earlier battle and felt somewhat tired. He planned to return to his room. Athena followed him.
Seeing this made Erica secretly grit her teeth in anger, but she was helpless. That Heretic God was stuck to her Yusei-sama like glue, giving her no opportunity to tempt him.
Her originally planned 'night assault' couldn't be carried out.
Yusei returned to his room. No sooner had he lain down on the bed to rest than he heard the door open. The cute, petite Athena walked in.
Seeing this, Yusei sat up and pulled Athena to sit beside him.
"What's wrong? You look like you have something on your mind."
