Honestly, this was rather unbelievable. He could believe that Devil Fruits might grant the ability to control Genjutsu, but according to the Devil Fruit Encyclopedia, there was no Devil Fruit capable of making people enter illusions.
Devil Fruits could only grant indirect Genjutsu abilities. For example, Gecko Moria's Firefly-Shadow Fruit caused people to briefly enter an illusion when shadows were extracted or implanted.
Then there was Big Mom's Soul-Soul Fruit, which likewise caused people to briefly enter an illusionary state when souls were extracted.
Of course, there were other examples as well, but they all only caused people to enter illusions indirectly. None of them could make someone enter an illusion with a single glare like Mu Chen could.
Thinking of this, Zephyr grew very curious. "Mu Chen, use your Genjutsu on me. Let me experience it."
Mu Chen did not think much of Zefa's request. "But Teacher Zefa, you can't be on guard. With an admiral's strength, my current ability won't be able to affect you otherwise."
"Got it."
Zephyr then relaxed, and Mu Chen directly activated his Sharingan. This was the first time Zephyr had seen Mu Chen's Sharingan up close. He had to admit, those eyes were captivating.
The next second, while Zefa had his guard down, his gaze began to turn dull. Mu Chen knew that his Genjutsu had worked.
Mu Chen's Sharingan had already reached the Three-Tomoe Form. He wondered how long it could affect an admiral. Just as Garp had said, if someone at the admiral level wanted to break free from Genjutsu, it would probably take only 0.5 seconds.
Mu Chen simply waited for Zephyr to regain consciousness. At that moment, inside Zephyr's mind, he stood before the door of his own home.
Zephyr was stunned at first, then the door suddenly opened.
"Father, you're back!"
The one opening the door for Zefa was a young boy, whose appearance was seventy percent similar to Zefa's. The instant Zefa saw him, he became excited. "Dear, hurry and come in. I've already prepared the food!"
At the same time, a beautiful woman appeared at the door. Zefa could no longer hold himself together. Tears streamed uncontrollably down his face, and in reality, tears flowed from the corners of his eyes as well.
"Teacher Zephyr..." Mu Chen had no idea what had happened. Why was Zephyr crying? The next second, Zephyr woke up. The moment he saw Mu Chen, an indescribable feeling rose in his heart, but there was nothing he could do.
Zefa took a deep breath. "Mu Chen, thank you."
Mu Chen was even more confused this time. Why was Zefa suddenly thanking him?
"Mu Chen, you let me see my deceased wife and child. They were so real."
Though it had only lasted a few seconds, Mu Chen finally understood. Still, he felt deeply sorry for Zefa's experience. But the next second, Zefa wiped away the tears at the corners of his eyes.
"Your ability is very powerful. Although I wanted to remain in that illusion, my strength is what it is, and my instincts made me struggle free. So it took me less than three seconds to break out. If I had fought it with all my strength, I estimate it would take about one second."
"And your Genjutsu lets people see either the scene they find most unbearable or the one they most want to see. It's a very good ability."
Mu Chen had actually done that deliberately. There were many kinds of Genjutsu, and the most effective ones showed people the scene they least wanted to see or most wished to see. There was also Illusion Cage, but it was not very effective against someone this strong. After all, he had already tested it on Garp. Another method was for Mu Chen's consciousness to enter another person's illusion, but his current ability was still lacking.
"The strength of my Sharingan is still tied to my own strength. The stronger I become, the stronger the Sharingan becomes."
Mu Chen had tested this as well. Not only would upgrading the Sharingan make it stronger, but increasing his own strength would strengthen his Sharingan too.
"So you know that, yet you still want to slack off every day? Now that you've become my student, I won't let you slack off anymore."
Zephyr abruptly changed the subject. Good grief, he changed his attitude fast. Wasn't everything fine just now?
But that put Mu Chen in a difficult position. "Teacher Zehua, slacking off is my life creed. Otherwise, I might as well die."
"Hey!"
Zefa was utterly infuriated by Mu Chen's words. How had he never seen a student like this? A Marine like this?
"Teacher Zephyr, everyone has their own creed in life. But don't worry, even if I slack off, I'll still become very strong."
"You brat, you dare say that? You've got quite the nerve!"
"If I ask you to learn Armament Haki within one month, I'll agree to let you slack off. Otherwise, you'll train properly."
Hearing this, Mu Chen felt that Zephyr's calculations were truly shrewd. Even freaks like Borsalino and Sakazuki had taken nearly three months to learn Armament Haki, yet now Zephyr wanted him to learn it in one month. Wasn't that simply bullying an honest man like him?
But after thinking it over carefully, if he redeemed it through the system, it would cost 10,000 Slacking Points. With his current double slacking identity, slacking off for three hours a day would earn him more than 1,000 points. Wouldn't that mean he could get it done in ten days?
That actually seemed workable. "But Teacher Zephyr, you can't stop me from slacking off this month. And you still have to agree to our previous deal." Mu Chen directly made Zefa honor their previous agreement, which angered Zefa greatly. He had seen that Mu Chen was truly a genius and possessed the Sharingan. He had wanted to nurture him properly, but why did he love slacking off so much?
"Teacher Zephyr, that's my only request. If you don't agree, you might as well send me back to East Blue to be a major."
"Mu Chen?"
"Mu Chen, you're going to be the death of me. You... Fine, fine. I agree."
Zephyr was truly enraged by Mu Chen. Good grief, I've never seen a Marine like this. Was he really that lacking in ambition?
Seeing Zefa agree, Mu Chen smiled faintly.
