Intruder In Rakshasa Street Arc
Jack is introduced sat down on throne telling Kelly, Norah and Gavin it's been a long time and asks how were there days being Requiem General. When Norah asks why does he wishs to meet just three of them, he stands up and relpies if he summonded everyone at once, they may attract unwanted attention and seeing how three of them showed up together, isn't that imposing enough. Claiming the King and Queen won't be making an appearance, so the duty of relaying the message to them will be carried out by him. He informs everyone the Special Action Unit will be abolished because Hale Camp has brought forth a great inconvenience, because his arrogance and conceitedness ruined there plans. With there orginal plan to be lunched a day later, due to his greed, Hale Camp rushed forward by himself the day before. Asking his younger brother Kelly if he has anything to say, Kelly tells him he'll leave it to the organization to deal with him. When Jack says they don't need to penalize him anymore, he asks did he know his brother died in battle in Rakshasa Street, presumably the act of Cao Yan Bing. Informing everyone even though Hale Camp's opperation failed, he managed to force the Divine Pearl of Xihe out of the Spirit Pagoda Tree and with it materialized, there objective has more or less been fulfilled by half. They already have the sacred weapon Kronos in there hands, and the only thing left to obtain is the Divine Pearl of Xihe and with that, they'll be able to form a legion of the strongest spirits. With the loss of the Divine Pearl of Xihe, the Spirit World will fuse with Requiem Street as one again. Invading and occupying the Spirit World that controls life and death of human beings will soon become a possibilty. They'll be able rule to both the human and spirits worlds, with everyone's wishes will be fulfilled. When Norah asks if that's so he'll go down to Rakshasa Street and wipe out Cao Yan Bing. Jack tells him to take it easy, and when the time for invashion comes, they will make enemys out of every Reqiuem General. Besides the headquarters of the Spirit Defenders, there are also a few strong Reqiuem Generals, with there main obstacle being the ones with a body of a Martial God. After Gavin mentions the birthrate of people with body of a Martial God, Jack says it's true, however there are three in the current era, and mentions the names of the three. Jack then mentions the names of those with the strongest Human Martial Spirits as they will be a problem for them, along with other people they don't know of. However
