"Go! Go! Go!"

Kuro waved his hand dismissively, "Do you want me to give you this reputation?!"

"Brother Kuro, I will earn my reputation through my own strength!"

Sentomaru didn't understand Kuro's sarcastic remark; instead, he took it as encouragement and clenched his fist, making a loud thud.

"Clatter, clatter, clatter..."

Kuro rolled his eyes and said as he walked back, "Speaking of which, now that you've officially joined the Navy, what about the Science Unit?"

"I'm the most discreet man in the world. I would never say that the punk bastards' 'SSG' is almost finished. Even for Brother Kuro, this secret cannot be revealed," Sentomaru said confidently.

Kuro smirked. "You've already said it."

"Forehead..."

Sentomaru paused for a moment, then realized what he meant and said, "This is what I wanted to say. No one can force me to say it if I don't want to. I'm known for my outspokenness..."

"Yes, yes, yes, the tightest man. Alright, stop nagging. You've officially joined the Navy. What's your rank now?" Kuro asked.

“Colonel,” Sentomaru said, “I am now a colonel.”

"Colonel, really..."

Kuro, with a cigar in his mouth, glanced at Sentomaru and said, "Fine, you're strong enough. Do a good job. The old man will teach you to me, and I'll give you special training regularly. In this world, you can't achieve your goals if you're not strong enough."

Especially after his battle with Charlotte Linlin, he is now eager to improve his strength.

As expected, my cultivation is still not enough.

We need to develop more techniques and a stronger physique.

Otherwise, they would always suffer losses when facing monsters of the Four Emperors level.
