In the forest of the Country of Waves….

Shang looks at the two graves in front of him and one of the graves has a massive sword which has been thrust into it.

Shang’s thoughts: Momochi Zabuza and Haku.

These two are the first strongest opponents that Team 7 faced. They are also key persons whose deaths that help Naruto to find his Nindou (Ninja Way/Path).

Shang’s glance moves from the graves to the massive sword.

Shang’s thoughts: What a pity….

Shang originally thought of saving them but the message from Orochimaru seems to be more beneficial. Orochimaru wanted to test out the results of Edo Tensei against Akatsuki and the Artist Team has been deployed.

The Artist Team consists of Sasori of the Red Sand and Deidara. The former believes that art stays forever while the latter believes that art does not. In spite of their differences in belief, their skills can make them an anti-army team.

However, during the start of the Fourth Shinobi World War, Sasori and Deidara were part of the first group to be sealed after being resurrected. In other words, Shang has four choices if he wants their skills

The first choice is to help Orochimaru when he purposely leaks out his location for ninjutsu experiments

The second choice is to join the Konoha squads who are sent to save kidnapped Gaara.

The third choice would be to fight them during the Fourth Shinobi World War

The last choice which Shang is unable to make would be either hunting down or joining Akatsuki. Shang has no problems going one on one with the Akatsuki members. The only hassle he finds is Nagato’s Six Paths of Pain.

Shang’s thoughts: Well, I will leave it till I face him… More importantly, Kekkei Genkai (Bloodline Limit) and skills of Zabuza and Haku…

During the Fourth Shinobi World War when Zabuza was resurrected and sent to attack Konoha as part of the group, he mentioned that he does not have it but Shang does not think so as so far he has not seen any ninja in Narutoverse whose released chakra would take shape as a demon face. Even the released chakra of a Jinchuuriki ninja like Naruto take shape of a burning flame. One can say Zabuza does not know he is a user of a Kekkei Genkai, and he does not know the correct way of releasing it. Shang even suspected Zabuza might be an orphan from Land of Demons and then take on the surname of someone who takes care of him. No proof of this has yet surfaced.

Shang walks to the side of Zabuza’s grave and places his hand in the center of it.

Shang’s thoughts: Pfftt… I did not expect them to bury you that deep… Probably Kakashi’s Earth Release did the job.

Shang takes out a shovel from mid-air and starts digging.

A few hours later, Shang finally could see the hands and feet of the bodies.

Shang’s thoughts: Here we go…. Hmm…?

Shang obtains something unexpected when he touches the bodies.

Shang’s thoughts: Techniques of White Zetsu...

White Zetsu are the first victims of Otsutsuki Kaguya’s Infinite Tsukuyomi and their real owner is Black Zetsu who is the physical manifestation of Kaguya Otsutsuki's will. Both of them have the ability to merge into one and function as a spy for the group Akatsuki.

Shang’s thoughts: At least it solves the mystery on how Kabuto obtained the DNA of Zabuza and Haku. The Black Zetsu has spore trackers on every generation of the Seven Ninja Swordsmen of the Mist all along. Hmm? But wait, if I can collect White Zetsu’s techniques, which means…

Shang quickly picks the shovel and returns the soil back to half-dug grave.

After Shang left the location for a few minutes, two white heads pop out from the grave.

White Zetsu #1: That presence, it’s him alright.

White Zetsu #2: Who is he?

White Zetsu #1: The one who single-handly defeated the Seven Ninja Swordsmen of the Mist.

White Zetsu #2: Huh? When was this information shared?

White Zetsu #1: You must be newly created. Here you go…

White Zetsu #2: Thanks, so do we report him to Zetsu?

White Zetsu #1: We should. Zetsu is looking for information on him.

White Zetsu #2: Then Senpai, please do the honors.

White Zetsu #1: Huh, why should I? Shouldn’t this job be for juniors?

White Zetsu #2: No, Senpai. You are the one should….

The two White Zetsu continue to squabble for a few months before Black Zetsu obtains the information.
