But all the wooden spikes stopped one or two centimeters from Yu's body, then fell to the ground one by one.
The armor made of Chakra Metal powder had no flaws whatsoever. Every part of it was fortified to the utmost. Its defenses would weaken only when Yu ran out of Chakra.
Obito's power was formidable to anyone else, but it wasn't very useful against Yu. As long as Yu focused entirely on defense, no one could easily attack his real body.
And with the Eightfold Seal in place, Obito's strongest means of escape was also blocked. Yu could slowly wear him down in this space. It was the easiest and simplest method.
Until the eight Yu clones ran out of Chakra, Obito could only remain trapped here. Of course, if Obito could muster more power than the eight Yu clones had combined, he would be able to break out.
The Eightfold Seal was extremely difficult to use, but its power was just as great. If Obito activated Susanoo, he might be able to break through it.
