But what is most attractive at this moment is not the blood-red and still beating heart, but the strange "卍" symbol above the heart.

The rune emitted a faint golden light and had a special Buddhist flavor, but the entire rune was reversed, revealing a strange and evil feeling.

"When you cultivate the Heavenly Demon Bloodthirsty Blade, or Shura Blade, to a high level, a rune like this will appear on your chest. I didn't quite understand it before, and didn't care about it anymore. But after being attacked by an evil spirit today, I finally understood the purpose of this rune..."

Xue Dao's face grew paler, but he didn't care.

"He's using me to cultivate a Gu. This rune has a special connection with this evil spirit... It can suppress my blood and energy, making it less afraid of me and even allowing it to easily break through my defenses. This is a vicious method used by barbarians..."

Zhang Mingtu stared at the rune and his heart moved.

That rune was exactly the same as the internal rune that was revealed before the death of the evil spirit controlled by the spy of the Kingdom of the Rising Sun whom he had killed in the underground river of Jianyi.

Judging from Zhang Mingtu's special eyesight after practicing the Acala Sutra, after the rune was imprinted in the body of the Blood Sword, it not only made the Blood Sword easily invaded by these evil spirits from the Land of the Rising Sun.

Even the rune was not only branded on Xuedao's heart, but also on his soul.

"If Blood Knife dies, there's a high probability that some strange changes will occur, and he'll become a powerful evil spirit."

"Is this the evil ritual?"

"It shouldn't just be a simple murder. If that were the case, they wouldn't have needed to send evil spirits to kill Hong Ji. There must be some special methods and means."

Zhang Mingtu had some guesses in his mind, but he didn't show them.

At the same time, he couldn't help but think of the Demonic Bloodthirsty Sword Technique and the unique Shura Sword.

"My future brother also practiced the Heavenly Demon Bloodthirsty Blade Technique, and he reached a very advanced level. At that time, he didn't seem to have the unique swastika symbol on his heart. It's very likely that the swastika was carved into the Blood Blade's body by other means.

"But that's not certain. Maybe that future brother hasn't noticed..."

Zhang Mingtu had some thoughts in his mind, but before he could figure it out completely, he felt the aura of the figure in front of him quickly weaken.

Blood Knife is dying!

It’s not because of evil spirits, the evil spirits have been suppressed by Zhang Mingtu.

It was because Xue Dao didn't feel like he had much will to live anymore, and he felt like he had lived enough.

The martial arts created after a lifetime of hard work turned out to be mostly inherited from the barbarians. Moreover, this martial arts had problems and could not be taught casually, otherwise it would fall into the barbarians' evil schemes.

This person, who had always hated not having a high-level inheritance and had always wanted to leave behind a top-level inheritance, didn't want to live anymore after knowing this.

"Are you going to let your inheritance be cut off just like that?"

Seeing that Blood Knife had completely given up resistance and the evil spirit was rapidly eroding his body, Zhang Mingtu spoke.

He didn't have much sympathy for Blood Knife. He didn't care even if Blood Knife died here. People like Blood Knife deserved to die.

His future brother had seen Blood Knife die once before, and he was more concerned about the special swastika symbol in Blood Knife's body. He wanted to study it more and have a deeper understanding of the Land of the Rising Sun.

"What else? Stay in this world full of regret and stench?"

"Even if I'm given more time, I still won't be able to perfect the Mingyue Sword Technique. Besides, I don't have much time left. In that case, I might as well just die."

"That's not necessarily true."

Xuedao didn't want to listen at all, but at this moment he suddenly sensed something, his expression suddenly changed, and he looked up and looked forward.

He saw that a scimitar appeared in the hand of the iron-masked man in front of him. The long sword was raised high. In an instant, in his mind, it seemed as if a bright moon rose from the sky. The bright moonlight involuntarily absorbed his spirit completely.

“clang!”

Suddenly, when Xuedao came to his senses, he felt a slight pain in his neck, but he ignored it. His eyes were as bright as stars, and there seemed to be a lingering trace of the bright moon in his eyes.

"What kind of swordsmanship is this?"

"Crescent Moon Scimitar."

"You perfected my family's swordsmanship? How did you do it?"

"When I was researching your information, I read it once and it came naturally to me."
