At night, Tsunade's home.
Mu Yue and Tsunade conducted a final review of all the development materials for the Yang Seal in the study.
With the assistance of Tsunade, the greatest Medical Ninja in the ninja world, along with his diligent study and practice of Sealing Jutsu, Mu Yue was finally close to completing his Power Bank Plan.
At that moment, Mu Yue was only one final step away from the Yang Seal he had envisioned: modifying and refining the Yang Seal already within his body. The theoretical groundwork was already highly refined.
"I'm exhausted. It's finally over." Tsunade slumped gracelessly into her chair.
"But it was worth it, wasn't it? Not only was my Yang Seal perfected, but you also completed the development of Creation Rebirth." Mu Yue said with a smile, taking a sip of tea.
While Tsunade helped Mu Yue perfect the Yang Seal, Mu Yue had also been helping Tsunade complete the development of the Ninjutsu paired with the Yin Seal.
Without Creation Rebirth, the Yin Seal was practically useless.
Tsunade rolled her eyes and said irritably, "You make it sound like we developed it together for mutual benefit. It's not like I was that desperate to perfect the Yin Seal."
Tsunade had only researched the Yin Seal and Creation Rebirth because she was bored and needed something to pass the time, not because she wanted to increase her combat strength like Mu Yue did.
Tsunade had no intention of returning to the battlefield, nor did she want to fight and kill as a ninja like she had in the past. She had no need to grow stronger at all.
If Creation Rebirth had not possessed a few other useful applications, Tsunade would not even have bothered researching it.
"This midnight meal had better be lavish.
