Spirit-Concealing Haori.
One of the Divine Artifacts the Shihoin Family had used to trade for Yushiro.
After confirming that no more guests would be coming, Su Feng took out the Divine Artifacts Shihoin Genji had sent and examined them closely.
As a textbook example of a cunning old fox, the man had thoughtfully included an instruction manual.
The Spirit-Concealing Haori was simple to use. One only needed to wear it and pour in a sufficient amount of spiritual pressure to conceal their own spiritual pressure. When paired with Bakudo #26: Curved Light, it could even achieve invisibility.
After giving it some thought, Su Feng spotted the problem.
Wasn't this the high-tech cloak Kisuke Urahara had developed?
After Urahara had been exiled to the Human World, Aizen had taken over some of his research findings.
The black cloak was one of them.
But now it seemed that Kisuke Urahara's inspiration for the invention had also come from a Shihoin Family Divine Artifact—
The Spirit-Concealing Haori.
After trying it a few times, Su Feng set it aside.
It was useful, but not particularly so.
It might fool an ordinary captain, but someone like Aizen was excessively cautious and possessed countless means of surveying his surroundings.
For the Spirit-Concealing Haori to deceive him right under his nose was rather unrealistic.
There was also the Spirit-Severing Rope, which Mayuri Kurotsuchi had once replicated.
The Shihoin Family seemed to possess quite a lot of this Divine Artifact. By rough estimate, this one was no less than ten meters long.
Su Feng tested it himself and found that it had excellent toughness and strength, more than enough to handle captain-class Soul Reapers.
In a sense, it could completely replace a Zanpakuto.
The Spirit-Severing Rope did not suit Su Feng's fighting style, and its strength was limited.
